Hello, how are you, dear reader?
Before you begin reading “The Alpha of the end of the world”, there are some important details I’d like you to consider:

Fanfic focused on Shigadeku (BNHA – Boku no Hero Academia).
Omegaverse: Shiggy is an alpha, Izu is an omega.

Longfic: This is a long story. If you don’t have the patience for slow and gradual development, this fanfic might not be ideal for you.
It’s also my first long fanfic, so please be polite.
I tried to keep it at a good pace.
The tribal names or terms used here are not real tribes or names, although some may be based on existing ones.
Poetic style.
The cover was made by me. I do not authorize the reposting of my fanfic or the cover anywhere.

No explicit scenes (no smut): Only mentions of the act, with no graphic descriptions.
Scene or POV changes will be marked with ............
At times it may be a bit rough; I’m still learning.

Content rating: 16+
Even without explicit sexual scenes, this story includes emotional themes, complex feelings, violence, pregnancy, mention of suicide, and also implicit nudity, possessiveness, and disturbing scenes such as blood and consumption of non-edibles. These topics are better understood by readers aged 16 and above, and may cause discomfort to younger readers.
Still, it remains a healthy relationship. There is no rape in this story.

Constructive criticism is welcome! Offensive or disrespectful comments will be ignored.

The fanfic is already complete; I’m just posting it now. Edits will only be made if there’s a real need.

The story explores the contrast between the “civilized human” and the “wild human,” touching on tribal concepts and different forms of social organization. There is no intention to offend or stereotype any people, individuals, or cultures.

I did my best to maintain logical consistency throughout the story. Some flaws may have gone unnoticed. I also tried to stay as respectful and faithful as possible to the original characters. In Tomura’s case, it’s more of a “what if” — he’s not exactly a sadistic and cruel killer here, more like a big fierce kitten. And Izuku is portrayed as a curious analyst, not over-the-top, just a little cinnamon roll.

This fanfic has already been proofread.

Izuku is of legal age, avoiding any politically incorrect romance.
It has also been translated into English. It was originally written in my native language and only posted in English, so there might be some translation mistakes. If you have questions, feel free to ask.

You’ve been warned!

Made with love.
Happy reading ＼(^^)／

Chapter Text

In the year 873 (in the Musutafu Kingdom Calendar), strict social rules governed the hierarchy of Alphas, Betas, and Omegas — the latter suffering most under this system. The place of an Omega was within the home, tending to the husband's needs and raising his children — nothing more. There had been no great achievements by Omegas... until now.

Izuku Midoriya, a nineteen-year-old Omega, possessed an adventurous heart. Since childhood, he had admired All Might — the Great — a legendary warrior and explorer. He longed to be like him, to explore as he did, even if All Might was but a myth. A small, scholarly young man (even if his mother, also an Omega, deemed the habit useless), Izuku was analytical, kind-hearted, and constantly seeking something to study in the hopes of discovering or creating something important — something that would make Omegas remembered as more than mere property.

Lately, Izuku had been suffering from a kind of "persecution" by neighbors and single Alphas. A pretty, sweet, and single Omega nearing twenty was taboo. He noticed the stares, the whispers, the indecent glances filled with desire. They thought he would make a perfect housemate — belly swollen with pups and submissive. Even his mother pressured him to settle down, stop wandering, and start a family like everyone else. But Izuku would not listen.

One afternoon, Izuku was at a tavern/restaurant in Musutafu's capital. He passed by there often after visiting the library, carrying an armful of books — mostly filled with tales of All Might. He couldn’t help overhearing a conversation.

"Have you heard about a mysterious island? They say savage tribes live there," said an elderly Beta, drinking with his companions.

Izuku's ears perked up with interest.

"If I approach them and ask about this island, will they be hostile?" he thought, hesitantly. Even Betas, though less frequently, harassed Omegas sometimes.

Summoning courage, Izuku stood from his table and reluctantly walked to the neighboring one. The men, upon seeing the young Omega approach, exchanged overly expectant glances. Many rebellious Omegas had turned to prostitution, offering themselves when finding Alphas and Betas gathered in one place.

But Izuku didn’t give them the chance to speak first. He got straight to the point:

— “Could you tell me about that island?”

The men exchanged glances again before bursting into laughter at the naive young man.

— “We might tell you, but not for free.”
— “What’s an Omega like you doing asking about that? Did your Alpha leave you?” said a bearded man. Izuku looked a bit startled, but would not give up so easily.

One of the men, slightly more sympathetic, decided to answer:

— “It’s an island discovered by sailors some years ago. Anyone who tried entering the Forest of Death… never came back. They say it’s home to cannibals, savages, barbarians.”

The man paused to catch his breath and continued:

— “The Palace has bigger concerns than caring about some island in the middle of nowhere.”

Then the Alpha softened his gaze and added:

— “If you’re planning something foolish with that young, silly head of yours... forget it.”

The other men, until then amused, grew irritated at their friend for ruining the fun with the little Omega.

Knowing he wouldn’t get more information, Izuku paid his bill and left. He walked home deep in thought.

"If All Might heard of this, he’d go without fear. Maybe he already heard of something like it."

When he got home, he greeted his mother and went straight to his room, where he left his books and studied until nightfall. At bedtime, he lay in contemplation — wondering what to do with this new knowledge. This could be his chance to make a grand discovery.

Sometimes, Izuku felt so pressured that he just wanted to run away. That night, he had a bold idea before falling asleep.

…………

Izuku had already planned his “escape” — or rather, his unauthorized expedition. He took a modest sum from his father’s inheritance, leaving the rest for his mother.

That morning, he would put his plan into action. He went to Inko’s room, kissed her plump cheek, and hugged her while she slept. Then he rushed out the door, tears of guilt running between his freckles.

Was it really worth it?

Walking through the streets toward the coast, Izuku found a modest, somewhat worn boat docked away from the main harbor. Nearby were the captain and a helper.

“All the money I took will be spent here,” he thought. Not that he’d need money on an uninhabited island. He’d decided: he would pay for a clandestine boat ride to the island. “I just hope this man knows the coordinates.”

The captain, seeing the Omega approach, hurried to speak:

— “You brought the money we agreed on?”

Yes, a few days had passed since the tavern conversation until Izuku finally decided to carry out this madness.

— “Of course I did.”

Izuku stepped aboard with some trepidation. The rocking of the deck made him feel like he was floating. “Wow.” He knew his mother would go mad if she saw him there. “The sea is incredible.”

Sighing, he pulled from his large backpack a blank notebook. He opened it carefully and began taking notes, murmuring softly to himself. He left space for drawings, in case he had time during the voyage.

He hadn’t paid the captain yet — he would do so only upon arrival. Now, the boat was already drifting away from shore.

“So this is it… I’m really doing this.”

By nightfall, he was anxious. The only Omega on board — accompanied only by two Betas. He had merely provided the location in exchange for alarmed and ironic remarks.

Now, he was in one of the small cabins below deck; his was on the left. He made sure to lock the door before sleeping. How many careless Omegas had been assaulted just for being alone?

According to his calculations, the journey would take seven days. Before retiring, he had the chance to gaze at the stars. Back home, he couldn’t do that without some lecherous Alpha watching. Now, the sky was his alone.

He drew a little, too — writing about the sea and his emotions.

Before departing, Izuku had written a letter of apology to his mother. He asked that it be delivered one day after he had set sail.

…………

And so the days passed.

Upon spotting land, Izuku was overwhelmed. The island was vast, more imposing than he’d imagined. The boat touched the sand, and he paid the agreed fare — the plan was to stay for a week and explore, perhaps find something of worth.

— “If you think we’re waiting for you, you’re dead wrong, Omega,” said the captain with disdain.

Izuku froze. He needed to come back!

— “But I paid what was promised...”

— “We’re not staying here. We could die just standing on this shore, with the reputation this place has.”

Tears were already running down Izuku’s face. He had always been known as a crybaby. Omegas were sensitive, but Izuku took that to another level. His reaction came as no surprise to the two men.

It didn’t matter how much he argued. Eventually, they tired of listening and began hurriedly preparing to leave.

Izuku was stranded. Forever?

Two cowards. One Omega showed more courage than two Betas combined.

They left an Omega to die.

He turned to face the towering forest. By now, he was partially regretting his decision. He had planned to spend a week on the island, then devise a way back. He hadn’t studied all his life for nothing. He also brought books — on navigation, maps, guides to plants and animals, and smaller tools that might prove useful. After all, his backpack was enormous, making Izuku look tiny under its weight. Omegas were naturally smaller... he looked almost cute carrying all that. So much so that the Beta helper had asked, days earlier, if he was married.

Izuku took a short walk along the beach, hesitant to enter the forest. If the island were truly so dangerous, shouldn’t he be dead already? There wasn’t much special at first glance — just a normal beach. He found some pretty shells and a few scattered mollusks.

— “I better enter the woods before nightfall... I’ll come back here later,” he murmured aloud. Izuku always had a habit of talking to himself — sometimes it got in the way. But it wouldn’t be Izuku Midoriya otherwise.

He took a knife for safety, though he wasn’t skilled in combat. Still, his brain seemed to hold emergency plans ready, as if it stored answers for danger without his realizing — a curious and comforting trait.

And so he entered.

At first, sunlight filtered gently through the leaves, but the deeper he ventured, the darker the forest became. He gathered plants, focusing on those unfamiliar to his homeland. Was the island still within Musutafu territory? Or perhaps no kingdom truly claimed it. That might explain the Palace’s indifference — just another island, filled with drunken sailor tales. Izuku considered that the stories might be unfounded, since, in theory, he was still safe.

Yet deep down, the boy felt a strange sensation as he entered the denser part of the forest. He could no longer see the beach, nor any bright sunlight. He ignored it, mostly — perhaps it was just his mind playing tricks. He was, after all, testing in practice how solitude could harm one’s sanity. That uncomfortable feeling of being watched, of being judged by unseen eyes... was it his imagination? “Of course,” Izuku thought.

If not, perhaps there were no barbarians, cannibals, or even tribal murderers at all on this island.Maybe the place had pheromones that induced madness. Maybe the sailors killed themselves, had hallucinations... but if they were dead, who was telling the story? Wait — Izuku swore he felt a warm breath on the back of his neck. He looked back, desperate. There was nothing. “I think I'm going crazy,” he murmured. Would he go crazy before he died? He noticed that the sunlight was getting even weaker through the gaps in the leaves. He assumed that the afternoon was ending. He quickly retraced his steps to the beach — there was no way he was going to stay there at night! He sighed in relief when he saw the soft sand. He set up a kind of bed that he had brought from his huge backpack and watched the waves reflecting the moonlight. He cried a little before falling asleep. His mother, his home... would he never see them again? He felt again, before falling asleep completely, the warm breath on his face... and a growl. Were they wolves? Cannibals? Wild? Felines? Or imagination?

Chapter Text

Izuku woke up with a headache.
— “What happened...?” — He was inside a cave, narrow at the entrance, feeling hot breath and breathing against his neck. A guttural growl.

At first, still half-asleep, he thought it was just his imagination again… until it hit him.
“How did I end up here?”

Opening his eyes wider, his first sight upon waking was two red eyes and large teeth.

— “AAAAAAAH!” — he screamed, which startled the creature.

The “creature” made a confused sound, something like a “grrhh?” The sound echoed through the cave walls, making the red eyes narrow at the high-pitched, irritating scream.

Izuku searched frantically for his knife, until he realized he only had the clothes on his back.

— “Where are my things?” — he shouted in panic.

So far, he was fine. He was afraid to look. He didn’t know who — or what — had kidnapped him. His green eyes slowly moved, cautiously, toward his captor.

It was a man. An alpha. But different.
Izuku had never seen such a muscular and massive alpha in his life. His skin and long hair were snow-white, with intense red eyes. His body was covered in scars — on his lip, over his eye —, a mole on his chin, and wounds along his neck. Deep marks, dark circles under his eyes, cracked lips.
Moreover, the alpha was covered in dirt, as if he had just crawled out from underground.

Upon noticing that, Izuku realized something... shameful.

The alpha was naked!

Once he noticed that detail, Izuku quickly averted his eyes, his face burning.

So the stories about wild tribes were true!?

The alpha also had elongated claws and large canines. It was surreal — Izuku had never seen such primitive features in alphas before. Was this what the ancestors of the First Class were like? Monsters?

The alpha approached, making the omega uncomfortable with the man’s nudity. Izuku didn’t know what his intentions were — did he want to abuse him? Kill him?
To his surprise, the albino began to sniff him like a dog, and seemed… excited.

Discreetly, the alpha seemed quite serious. His “excitement” showed only in wide, interested eyes and a micro-smile — or what looked like one. Then, he tried to lick Izuku like a dog, or a cat, while the boy pushed against the other’s firm chest with his hands.

“Are these wild people’s customs?”
The behavior was strange, primitive. Almost animalistic.

When he tried to push him away, the alpha growled — a dominant growl — which made Izuku freeze in fear and allow himself to be sniffed. He seemed aggressive. His pheromones were strong, overwhelming, mixed with his natural body scent.
Maybe this man doesn’t even know the importance of a bath...

The larger man poked at the clothes with confusion, and the fear intensified. To the alpha, that was bizarre — a second skin? What was it for? It only got in the way of interacting with his omega.

He had known it was an omega the moment he saw him in the forest, gathering plants. His keen sense of smell didn’t lie: the omega was young and unclaimed. He couldn’t detect any other alpha’s scent on him — so, obviously, he had to be his omega.
Not that he hadn’t seen lone omegas before — he just had no interest in them, nor did he ever bother to interact. But this one... this one was different. As if they were somehow connected.
But the alpha couldn’t name or explain it.

Tomura — his name (still unknown to Izuku) — from the Shimura tribe, or simply Shigaraki, as he was commonly called, had never had a mate.
An alpha had only one partner for life, mating only with them and raising their pups together.
But Tomura… was different.

A virgin alpha.
He’d never been interested in others from his old tribe, nor in finding a mate.
Tomura was a strong alpha. Omegas valued such alphas — strong enough to protect their families.

And he had spent nearly his entire life alone.
He showed no mercy to anyone who entered his territory.

That omega was an exception.

Tomura didn’t know why.

But right now, the alpha was bothered by the rags covering the omega’s body.
With his claws, he tried to tear the fabric — it was in the way.

Izuku, however, stopped him, desperately grabbing his hands.

The alpha furrowed his brows — even though he didn’t really have eyebrows, due to the markings around his eyes — and Izuku realized he was in trouble. His strength was far greater, and he couldn’t stop the albino man.

— “N-NO!” — he screamed again, into the alpha’s sensitive ears, who seemed shaken by the sound.
It wasn’t enough to stop him, until the tears returned. By then, the clothing was already torn, but Izuku was not yet naked.

Seeing the rivers running down the omega’s cheeks, the alpha froze and, for a moment, stared into his green eyes before pulling away primitively, using his hands on the ground, crouched.

The smaller one remained on the ground after that, until he was grabbed again.
Tomura took him by the arm and dragged him deeper into the dark den while the omega struggled.
The alpha placed him into a sort of primal nest, made of straw, leaves, and animal hides.
— “It’s his bed...” — Izuku murmured, frightened.
Apparently, the alpha didn’t understand his speech, but Izuku didn’t care whether he understood or not.

And the alpha left him there, exiting the cave silently.
Izuku waited a few minutes after his departure and tried to sneak out, moving toward the light of freedom.

Upon exiting, he found himself in a dense, dark forest. The cave was on elevated ground, its entrance embedded in a tall stone wall. Above, more forest. To reach the ground below, he’d need to descend carefully.
But just when he felt a glimmer of hope… he nearly died of fright.

The alpha was there — and for the first time, fully upright.

He was enormous. He must’ve been at least 1.80 meters tall, even more terrifying when standing.
When Izuku dared to leave, the alpha let out a guttural roar of rage. A warning? A reprimand? In that moment, it was impossible to tell.

— “GRRRRRAAAAA!” — His canines bared, lips pulled back, like a lion, a panther… or even a bear in battle.

The boy screamed and ran back inside, curling into a corner of the shelter.
The alpha entered right after and, with more low growls, pushed the green-haired boy down with one of his large hands — like a lioness does with her cubs. A rough gesture, but not cruel.

It was a sort of aggressive affection: soft hits and nudges with his “paws.”

Izuku stayed still, trembling, tears threatening to fall again.

.............

It didn’t make sense.
The omega was safe with him!
But water kept coming from his eyes. Trying to recall, that meant bad things — in his tribe, it was a negative sign. If they let water fall, it meant weakness. The individual was weak. It also meant that, at any moment, they could be killed.

He couldn’t allow that. No matter how weak his omega was… he was still his!

He ran his fingers over the omega’s damp eyes, as if trying to brush away the bad things.
Then, Tomura lay down beside him, arms and legs stretched out to the side, like felines do.
He stayed there for a few minutes, silently observing, before getting up and leaving again — checking carefully with a glance to make sure he wouldn’t try to escape again.
Then, he resumed what he had set out to do before… and vanished into the trees.

.............

Izuku didn’t have the strength to try escaping again.
He needed his things.
The cave had a strong smell — a bit of urine mixed with the alpha’s musk — but, considering his situation, that was the least of his problems.
What had the wild man gone to do?
Deep down, Izuku was curious about his customs — it was a study opportunity, if only he had more courage.
But his omega instincts forced him to be submissive, which was everything he stood against.

.............

While his captor was gone, he fell asleep.
When he woke up, the smell of urine was much stronger now — until he felt a sniff on his neck and warmth at his back. It was so dark outside.
Wait!

Izuku looked behind — and the man was there, behind him, body pressed to his, an arm wrapped firmly around his waist.

He remembered, with a shiver, that the alpha was naked. Pressed against him!

— “Aaaa… no,” — he whispered, startled.

He tried to lift his upper body, but the man also startled. He grunted, muffled and possessive, preventing his omega from getting up.

Until Izuku heard a purr — a soft, continuous purrrr.

Izuku was surprised. He didn’t know alphas did that... or maybe it was something from the ancestors, those who lived before modern times.
Maybe this island really was a fantastic place — a land where ancient versions still walked outside of time. Or was it a forgotten ability, hidden by the progress of civilization?

Izuku fell quiet again, feeling the warm breath of the alpha behind him, and the long hair falling over his shoulders like a soft curtain.

He fell asleep once more.

.............

He woke early again — the sun was beginning to rise. His omega still slept, calm, serene… beautiful. So his.
Tomura could already imagine a future family — with pups, a full nest. But before that, he needed to win over his omega. The right way.

He stretched and went off to hunt.

He walked for hours, as he did every day. He found a large deer grazing in an open field.
There was one problem: his albino skin was sensitive to the sun and far too conspicuous. He needed to be quick.

Fortunately, Tomura was a master of silent steps. A born predator.

He crouched in the tall grass, controlling the weight of his body, softening his steps. The deer didn’t feel death approaching.

Usually, Tomura hunted easier prey. But now he had an omega to conquer. He was already his — but an omega needed to trust his alpha, to know he was strong enough to take care of him.

He jumped. Landed on the deer, digging his claws into the soft flesh. The animal struggled, trying to shake off the predator on its back, until Tomura slid down, clinging tightly, biting hard — a precise strike. His canines pierced the flesh, and the deer slowly began to lose its breath.

Tomura wasn’t unscathed. Some open wounds burned, deep. But he was resistant to pain. The scars on his body were like trophies — marks of the fights he had won, proof that he was strong.

He dragged the lifeless deer’s body back to his territory.

It was a long walk. Two, maybe four kilometers — Tomura didn’t know what a “kilometer” was. But you know: it was very, very far.

..........

Izuku woke up to a strong smell of raw meat and saw the man in front of him, offering a piece directly to his mouth. He was trying to feed him. He turned his face, trying to push the head away. The alpha, however, seemed proud, with a smile of pure contentment — of course, in his own way — while Izuku made a disgusted face, wrinkling his nose at the smell of blood.

“Ew…” Izuku murmured, shrinking back.

“Hhhr…” the albino grunted, seeming confused and frustrated by the refusal. Why would his omega reject such a humble gift?

Irritated, he dropped the piece of meat on the ground and moved away, going to eat the carcass alone, thoughtful.

“Maybe he has a super-strong immune system to eat meat like that…” Izuku thought, intrigued. A human needed food to be sanitized.

With some disgust, he looked away from the horrible scene: the dead animal being torn apart by the savage’s teeth. Blood gushed from the albino’s teeth and hands, along with pieces of the animal.

Maybe… he just wanted to be a kind?

Chapter Text

The omega was starving. He hadn’t eaten in two days.
Tomura had offered the dead deer countless times, but the boy kept refusing, and he couldn’t understand why.
The meat was nutritious, perfect for strengthening the body—so why was it rejected?

The alpha could hear the rumbling of the stomach from afar. The little one curled up more and more, always turning his back to the meat. Whenever he happened to see it, he had a gag reflex.

That was strange to Tomura. If he was hungry, why wouldn’t he eat?

Could it be that he had a defective omega?

Weak.

He smelled wonderfully sweet and was fertile, but he looked like a slowly dying animal. Tomura watched the omega squirm and moan, holding his stomach, curled up like a ball.

The animal skins under his partner’s body were very different from anything he had ever seen. And why cover himself with them? They only got in the way of interaction.

It was hot outside, and inside the den it was only a bit cold—Tomura could warm him with his own body, so those skins were useless. He tried to remove the pelts from the omega, but he seemed upset, hurt, but still strange. He decided not to insist for now.

............

Izuku watched the alpha leave again. He wouldn’t eat raw meat—if only he had his things… He decided to try to follow him despite his weakness, and surprisingly, he wasn’t scolded this time.

But now there was a new, small problem: the alpha was glued to him, aware of every step he took since they’d left.

Izuku needed to relieve himself and look for fruit to eat. Yes, he hadn’t done anything for two days, due to lack of food and water. He had even peed in his clothes. He really wanted to change now.

The smell of urine in the cave… Now he realized it was all over the place. But it wasn’t his pee’s smell—he was sure of that.

Izuku knew himself well enough to recognize that his own urine didn’t have a strong smell. He was puzzled by why the odor was so strong around them.

His thoughts broke when he saw bananas on a banana tree—FINALLY!—he ran over with his heart racing. The alpha naturally followed, stuck to his heels. Izuku grabbed the fruit, but…

— Grrr... — a deep growl cut through the silence.

............

That thing the green-haired boy picked up… the alpha had no idea what it was. It could be poisonous. Was he really planning on eating that? Meat was way more nutritious than that yellow thing! The Shimura didn’t eat anything like that, so in the albino’s mind, it clearly wasn’t edible.

He growled. It was his way of saying it was dangerous.

— Oh, you don’t eat bananas? They’re healthy — Izuku said, and even with the warning, he put the fruit in his mouth. And… he seemed happy? What was causing that reaction?

Izuku savored the first bite with a relieved smile. Tomura, with a clear expression of “I don’t like your attitude,” watched as the omega extended the fruit to him.

— Try it, you’ll like it.

The alpha sniffed it suspiciously, then licked it, made a face… and took a bite. He kept the thing in his mouth for a while before spitting it out. It was disgusting, and there was still the fear of poison.

— No, no! — Izuku exclaimed, scolding him with a worried look. Seeing the alpha’s negative reaction, he bit into the banana again, with gusto.

— See? It’s not dangerous at all.

If he approved, then it was safe, right? Tomura fought against his instincts screaming not to let the omega eat that… but it was that or watch him starve.

He still didn’t like that thing called banana.

............

Izuku ate more bananas and gathered several in his arms. It seemed like the alpha intended to continue the walk, but he kept turning his head to make sure the omega was following close behind. It was almost comical… if it weren’t so strange.

Then an unexpected scene unfolded before his green eyes: with each step, the man peed on everything. It was shocking. Izuku averted his eyes whenever possible.

— I think he’s marking territory… — he murmured, intrigued.

Where did that behavior come from? Did all the alphas on the island do this, judging by the pattern? The urine was loaded with pheromones, allowing other alphas to recognize the territory by scent. Another peculiar habit he noticed was rubbing against tree trunks, like big cats, leaving his scent as a declaration of ownership. It all made so much sense now…

History books mentioned similar behaviors, remnants of a past that modern society preferred to forget. But… maybe it had never disappeared. Maybe it was never really evolution—alphas had always been like this.

“If only I had my notebook.”

“I hope I find a stream to wash my clothes and drink… but I need distance from him to bathe,” he thought, hoping the alpha would leave him alone for at least a few minutes.

............

Actually, Tomura hadn’t wanted to take his partner on that patrol. It was something he did every day—except for the first day the omega was in his home. The routine was simple: sleep, patrol, hunt, and drink water around the area. He would stay isolated for days when he had enough meat. Taking Izuku along meant taking risks.

He peed all over his territory and inside the den, except for the nest where he slept. It was instinctive to mark the space, but he never defecated inside the cave—that would attract annoying insects.

He noticed that the green-haired boy didn’t seem well. That’s why he let him out: maybe he needed to relieve himself, get some fresh air, and maybe even accept meat if offered again.

Tomura had also noticed that he’d peed on those strange pelts.

They found a pond. The waters were so clear you could see the bottom easily. Izuku knew he needed to find a way to wash himself, but he didn’t know how he would manage it.

To the albino, nudity seemed completely natural—almost primal. But to him? How could he just strip naked in front of that alpha?

His face flushed just imagining it. The discomfort grew in his chest, but so did the need to get clean.

Then a crazy idea popped into his head. It might fail, of course, but… nothing ventured, nothing gained.

He tore a small piece of his pants and, with careful steps, approached the alpha. Without saying anything, he blindfolded the alpha’s eyes with the improvised fabric.

— Grrr? — Tomura growled, clearly confused, trying to remove the thing now covering his vision. How could he protect his omega without seeing? Danger could be lurking anywhere.

He tore off the blindfold in irritation, but the smaller one’s delicate hand pulled the fabric back up over his eyes, firmly yet gently.

— Keep this — Izuku said softly.

The albino froze, more confused than ever.

Izuku placed the large, strong hand on his shoulder so the alpha would know he was there, that he was safe. He guided him into the water. The cold made the larger man flinch and growl in disagreement, still trying to remove the blindfold and get back to the shore. Izuku stopped him every time, his hand still guiding the alpha’s.

In the slightly deeper part, he began undressing and, now naked, started washing himself. Tomura sensed this because the sweet scent became stronger, and he realized he could no longer feel the strange fabric’s texture under his hand.

It was no secret that Tomura wanted to start a family, maybe even form a new tribe with his partner. He wanted cubs, but he was still in the courting process.

Still embarrassed, even with the alpha unable to see, he was still there. Later, he guided the alpha back to shore, knelt, and Tomura did the same, still with his hand on the omega’s shoulder. Izuku began washing his clothes.

The alpha remained blindfolded until the clothes dried and Izuku could dress again. He felt good being clean, and the bad odor had disappeared. He also drank some water. Once fully dressed, he freed the alpha from the blindfold, who seemed happy to see him well and whole—but still uncomfortable with the strange pelts on Izuku.

That’s when he noticed the albino man was dirty too. Maybe he should teach him about hygiene.

He watched Tomura drink water and noticed his peeling skin, poorly healed wounds on his neck, dirt all over his body, chapped lips, and many other signs. Everything indicated his skin wasn’t exactly healthy, besides the habit of scratching his neck—maybe he had mange. He needed a bath!

Izuku pulled him back into the water, soaking half his pants that were already dry. Naturally, Tomura was confused—and annoyed by the cold water again. He’d been completely dry before entering, and now he found himself soaked once more.

Izuku began cupping water with his hands, splashing it on the wild, smelly man in front of him, avoiding looking directly at his private parts. Even though the albino didn’t care about nudity, Izuku wouldn’t do to others what he didn’t like done to himself.

Obviously, the wild man reacted aggressively, retreating from the water. Izuku then used light emotional blackmail, giving him a look worthy of a kicked puppy. The alpha hesitated… and returned. But he didn’t give in easily: he let out a deep growl the second time water hit him.

Realizing he wouldn’t convince him with forced baths, Izuku decided to change tactics. He approached and lifted the alpha’s lips to examine his teeth. They were yellowed from dried blood stains over time, but otherwise normal—except for the elongated canines, like a wolf’s, perfect for tearing meat.

He tried to at least clean that by pouring water over his teeth… but Tomura nearly bit him. Pure reflex—Izuku was sure of that.

They returned to the den. The smaller one was exhausted from so much walking, and it was already late afternoon. If he could gain enough of the wild man’s trust, maybe he could go to the beach to get his belongings, but for now, this would do. Izuku lay down in the nest, and Tomura behind him, as was customary for the Shimura—or Shigaraki—the alpha always lay behind the family, warming and protecting them...

And, once again, Izuku slept peacefully, without understanding why, just like the first time.

—Soru — Tomura spoke softly.

Chapter Text

After three days since his bath, Izuku felt dirty again. The alpha always brought bananas—perhaps he had realized that the fruit was good for his health—but he was starting to get sick of them, even if they satisfied his hunger. Still, it was better than raw meat.

“Maybe I could go out again to look for something…” he murmured.

The man had left again, likely to relieve himself and hunt. Izuku didn’t like being alone; he felt defenseless. More and more, he noticed how being close to the alpha made him feel safe, even though the discomfort of nudity remained.

He had noticed a pattern: his companion always brought him bananas, sometimes large prey or dead birds—like a cat bringing gifts to its owner. Sometimes, flowers, which Izuku appreciated greatly. Their sweet scent masked the bad odor of the cave and brought some cheer to its darkness. Once they wilted, he would throw them away.

The man also seemed to listen to him more, as if his voice held importance. Even without understanding his language, the man paid attention to him—and Izuku noticed another detail: he had never heard the man speak. Not a single word.

..........

He had officially started his courting process, bringing gifts, as alphas usually did. It was a behavior he had observed in his old tribe: alphas offered many gifts to win over their partners.

And his omega seemed happy with the flowers and those yellow things. Still, Tomura disagreed with the rejection of meat—he didn’t want his partner to become malnourished.

At that moment, he was patrolling. He traveled great distances every day. Alphas were naturally muscular, and the large amount of exercise—hunting, fighting at times, walking, and on rainy days, running—kept his body fit. He hated getting wet.

He could already imagine it: his pups, and his omega happy.

He had been alone for so long that even he found his behavior strange. He would never have known how to care for someone without instincts to guide him… but somehow, his subconscious seemed to know exactly what to do.

He needed to keep his territory protected if he wanted his omega to have pups safely. That included patrolling daily. He already did that before having a partner, more out of habit—it was a basic teaching all alphas followed. But deep down, Tomura didn’t really care about his own life. And it would also be bad to lose the territory.

But with his little one… everything changed.

He began caring about himself—a new feeling. He needed to return. Someone was waiting for him this time. Someone who depended on him—and if they had pups, would depend on him even more.

He stopped his reflection when he caught an unfamiliar scent. Immediately, he froze, attentive to the air currents. The smell came from the north, slightly beyond his borders. At each river he passed, he drank deeply—he constantly needed his own urine. It was a powerful weapon for any alpha. He had to discover the source of that smell. He was still too far to distinguish whether it was an alpha, omega, or beta, but he couldn’t take chances.

He advanced, going beyond his border. The scent became clearer: it was an alpha. Much older than him.

Experience against youth.

Tomura was young—twenty-five years old—though he wasn’t aware of numbers or the notion of time.

But he would take the risk. That intruder might catch the delicious scent of his omega. Losing him would be unbearable; he could not lose his new reason to live.

The enemy was dangerously close to his border. A solitary alpha, with some strands of gray hair from old age—not naturally white like Tomura’s, which were pure white.

Like him, the new enemy also had a sharp sense of smell—and had already noticed him.

“Shuk! SHUK!!” Tomura shouted.

Acting on impulse, Tomura charged toward the intruder, teeth bared, muscles tense like a bull ready to strike. The opponent responded in kind, running straight at him.

Next, their bodies clashed like stags fighting for a mate—the impact reverberated through the muscles of both.

Then came the claws, the blood, the bites, and the growls.

The older man was more experienced, but Tomura had the advantage of youth: he was stronger, more agile. The other was already worn down by time. Perhaps that’s why he was alone—maybe he had spent his youth isolated and, now in old age, tried to steal omegas from other alphas, failing every time. His many scars made it surprising he was still alive.

When everything seemed lost, the enemy delivered a precise blow, pinning Tomura down. But that move doomed him. By forcing Tomura to the ground, he left part of his neck exposed.

And even pinned down, the albino sank his teeth into the adversary’s flesh.

It was his favorite technique.

He won.

His next action was to eat a considerable piece of the dead body—a Shimura tradition. When an alpha defeated another, they had to devour part of their enemy, believing that the opponent’s strength would transfer to the victor. A cruel, but cultural, cannibalism.

After that, the weakness from blood loss hit him hard. He wanted to go home and sleep for hours and hours. But he couldn’t stop now.

He hadn’t hunted yet, nor gathered the yellow things, and parts of the territory still lacked his scent. He had to finish his duty.

..........

The alpha arrived at his den. Izuku felt immediate relief upon seeing him. Why do I feel this way? he wondered.

But the albino man was covered in blood and panting, carrying a wild boar carcass and a bunch of bananas over his shoulders. He was visibly exhausted.

“What happened?!” the omega exclaimed with those strange sounds, which Tomura didn’t understand.

Worried, the green-haired boy dropped everything onto the cave floor and rushed to the nest.

Seeing the deep wounds and his partner’s exhaustion, Izuku decided to act.

He left the den, ignoring the protests: “Grrrraa! Shuk! Shuk!” came the alpha’s growls and strange sounds, but he was too exhausted to follow him.

Walking around the area, his eyes sparkled when he spotted a medicinal leaf. He nearly screamed with joy.

He quickly returned, gently blew on the leaf, stopped the bleeding with a piece of his already-torn clothing—what remained of his garments—and then applied the leaves over the wounds.

Still irritated, the alpha watched him through half-closed eyes, slightly curious.

He had a strong omega.

Tomura fell asleep while being cared for. He definitely didn’t deserve this. And more than that—it was his job to take care of the omega, not the other way around. This would not happen again.

As he lay down, the smaller one curled into his arms. He feared the night and the sounds it brought— it seemed like wild animals roared all night long.

..........

He woke up feeling better. Perhaps his omega had worked a miracle with those leaves— a power, an ability, something… It was surreal that a plant could ease pain like that.

“Stay down!” Izuku said when he saw him trying to get up. But Tomura needed to fulfill his duties! Izuku didn’t understand that.

The omega picked up the yellow thing and offered it to Tomura, who rejected it with a slap, sending it flying. Patiently, Izuku retrieved the food and offered it again. This wasn’t healthy—it shouldn’t be happening! Tomura, irritated, finally accepted it, only because Izuku insisted.

“It’s good for you!”

“Grr! Grrr!” Tomura pointed to the boar as he growled, asking for meat. Izuku looked at the carcass and decided not to comply. It was heavy, covered in fur… He wouldn’t know how to butcher it.

“Grah!! Grah!” Tomura demanded again, impatient about his untouched kill.

“If only I had my knife…” Izuku muttered.

Tomura lost patience. He stood abruptly. His wounds reopened, some leaves fell away. He was resistant to pain, but not invincible. Still, he ignored it all. Whenever he was this badly wounded, he usually isolated himself in the cave until the wounds healed on their own, hoping his scent would last long enough for him to recover. As mentioned before, Tomura never really cared about his own life—not before finding his beloved.

He went to eat his precious food. After the sweet banana, Izuku didn’t stop him—this time, he simply gave a scolding for the impatience, even though the alpha didn’t understand.

..........

The next day, the alpha was already back to normal. He woke up before Izuku, as usual. The safety of his territory couldn’t wait.

The omega woke up alone, still worried, anxiously awaiting the alpha’s return.

And then… he returned.

And with his chest puffed out with pride. He walked as if silently saying: “See? I’m strong. I can protect you… and our pups.”

Izuku ran to him, relieved, but was surprised by something unexpected.

The alpha gently pulled him close and began licking his neck, with slow, deliberate care. Izuku froze for a moment. It wasn’t a lascivious touch—it was almost ritualistic—an ancestral custom of the Shimura.

For Tomura, this was care. Cleansing. An intimate and protective gesture. Shimura alphas never used water; water was for drinking. The body was cleaned with the tongue, with the warmth of those who belonged to the same clan. The act of Izuku bathing alone was almost offensive, a mistake in that proud alpha’s eyes.

Izuku didn’t understand… but he didn’t refuse, surprising even himself.

Chapter Text

That day marked twenty-five days—or perhaps fewer—since Izuku had arrived on the island. He had stopped counting; his new life and its demands left him distracted. Like on some previous days, he felt filthy—and sick of bananas. He was hoping his partner would let him go out again; maybe he could find that crystal-clear lagoon or even some other fruits to eat.

Having gone so long without washing—he had only bathed once on the island—he sometimes rolled on the cave floor, in patches of fine dirt. The soil worked like a gentle abrasive, but it didn’t replace a proper bath with water. He also scrubbed his clothes in the same spot when the alpha wasn’t around.

There didn’t seem to be any insects in the cave, and during the day it was partially illuminated. Tomura seemed to keep the place clean of bugs.

At the beginning, Izuku remembered he had tried to escape during the first nights—without success—because the alpha would wake up at any sudden movement. Didn’t the narrator tell you that? Well, some things stay hidden until the right moment. He once had the chance when the alpha wasn’t there, but he didn’t go. That forest was far too dark.

At times like that, Izuku missed home, where everything was easy and comfortable. But imagining going back to his previous life without that wild man in it was difficult.

Whether he liked it or not, Tomura was his companion—and there were so many fascinating behaviors Izuku wanted to record and compare with historical accounts.

But it wasn’t just that. The alpha’s constant nudity, his beautiful and attractive body... He took care of Izuku. Made him feel safe. Loved.
But Izuku would never admit that—never. He had never felt anything like it before, as if that alpha could solve all his problems.

The alpha only let him out to relieve himself and drink water, since there was no container to bring it back. Once he finished, the pale man would call him back harshly, clearly wanting him to stay safe.

Of course, Izuku respected his partner, avoiding looking at his private parts, even though it was hard not to notice. He could tell the alpha was still frustrated by his clothes, as if he couldn’t understand why Izuku wore them.

The gifts began to increase. Now, the alpha didn’t just give him fruit—he offered it directly to his mouth, like a bird feeding its chick with worms. Beyond that, Tomura started bringing pretty stones, with curious shapes and colors. It was an instinctive behavior, very similar to courtship rituals observed in some bird species.
But Izuku wasn’t sure what to do with them.

At least the flowers—even if temporary—and the stones gave some life to his new home in some way.

And now, the alpha’s intentions toward him were clear. Yet, strangely, Izuku couldn’t bring himself to feel bothered by it.
He wanted him as a partner.

Izuku could tell how different this alpha was from the civilized ones—not only in appearance or behavior but in the way he related to others.
This one seemed to care. He courted, cared for, brought him gifts.
The alphas in Musutafu, on the other hand, seemed always to seek the same thing: fun.
And even when they wanted something more serious, like marriage, the rule was always the same: have pups, take care of the home, satisfy my needs.

Not that Izuku had ever been in a relationship—he hadn’t. But he had learned by observing and listening to others.
Besides, it was obvious.

It was a miracle Izuku had learned to read and write.
Omega literacy wasn’t encouraged.
He only got that chance because of a familiar teacher: Mr. Aizawa. Despite his bad temper, it was he who taught Izuku—and he also seemed to disagree with the imposed rules.

What was the point of an omega learning to read if their destiny was already written?

His own mother couldn’t read.
Even though she had the same opportunity with that teacher, she chose to remain in ignorance.
She worked as a housemaid—besides surviving on the inheritance.
The gold coins left by his late father eventually became the family’s main source of support.

How was she now?

.........

His omega was in the nest. Tomura purred in satisfaction.
He had improved his courting gifts with stones, as he had seen other alphas do in his culture.
Later, he would move on to precious stones—much harder to find.

He would spend a few days with his omega, but just a few—one or two at most—because of the need to patrol and protect his territory. He took advantage of seasons when there was plenty of meat to isolate himself in the nest, like now.
It looked like it was going to rain, so he had brought many yellow fruits for his omega to eat. They could drink from the water that fell from the sky.

The only difficulty would be relieving himself in the rain—he hated getting wet. Still, after two days, he would return to his activities. Even if it was still raining, he would go.

But his plans were interrupted when his omega stood up, grabbed his arm, and pulled him, pointing toward the narrow entrance of the cave.

— Shuk! Shuk! GRRR — Tomura growled in refusal. Why did he want to go out there? The first drops were already falling. Tomura had been lucky to arrive just before the rain started.

Izuku insisted, pulling his arm harder. It was starting to get annoying.

Tomura huffed but eventually stood and followed his omega. Outside, the rain intensified. To his surprise, Izuku looked happy, letting the water fall over him naturally.

Tomura watched from the cave’s entrance, staying dry.

The rain washed his body and his clothes at the same time—only advantages for someone filthy.

Izuku lifted his face to the sky, opened his mouth, and drank the rainwater with ease, as if it were something natural... and beautiful to watch.

Izuku didn’t stay long under the falling water. He was afraid of getting sick. He simply enjoyed the moment and soon returned inside.

Later, he would try again to teach hygiene concepts to the alpha. But this time, Tomura didn’t seem pleased with his behavior.

He waited until he was completely dry before returning to the nest. Tomura was already there, waiting for him, watching in silence.

Izuku, meanwhile, was already planning the next day—he wanted to go out again, look for new fruits, and explore a little more.

Then Tomura opened his arms in a silent request that made the omega blush.

The alpha’s body was warm, heating the cold nights.

Izuku went to him, curling up in his arms.
— Ppprrrrrrr — Tomura purred in satisfaction, repeating the gesture from a few days ago: licking Izuku’s partially exposed shoulders and neck, trying to remove the remaining raindrops.

All Izuku could think was that this man seemed like a needy, loving cat.

.........

To Tomura’s surprise, it didn’t rain the next day.
Maybe Izuku’s beauty had scared the rain away? His omega seemed like the sun itself. A sun that warmed but didn’t burn.

But that wouldn’t stop him from staying isolated that day.

Until the omega prevented it. Couldn’t he see that Tomura wanted to spend the entire day with him?

Now they were outside again. Tomura kept a close eye on him while Izuku seemed excited, exploring, scanning the area with those beautiful eyes—he looked like he was searching for something.

Uhhh... cute.

They walked a little farther, and Tomura started feeling uneasy with how far they were from shelter. Going further still, Tomura suddenly heard Izuku’s... excited cry?

They had found some small red berries in the bushes, and his omega looked so thrilled about it.

Just like with the yellow things, Izuku tried to eat them... until Tomura stopped him, like before. It could be poison.

And, just like last time, Izuku offered them to him, and just like before, he spat them out—they tasted different, but the green one seemed to enjoy the flavor.

.........

Luck was on his side—they were blueberries, bright red ones.
His hope of finding new foods grew stronger. He even tried to make the albino taste them, but he refused again.
Izuku laughed at the funny and cute sight of him spitting them out—he looked like an adult trapped in a child’s body, so tender yet so tough at the same time.

They returned home, and Tomura added more colorful things to his collection to bring, and finally, he could stay with his omega for two whole days.

Chapter Text

He missed his things terribly. He could have done so much if he had his backpack. Inside it were his books, a mini fire torch, the knife... items that would have been extremely useful now. He could tell Tomura was getting frustrated with his refusal to eat meat. It was still frightening to see him eat it raw—the crunching sound was unsettling. If only he had that mini iron torch, he could keep the fire burning longer than with wood... and then, roast the meat.

Tomura hadn’t gone out that day. He just lay there, clinging to Izuku all the time, purring and licking him. Up to that point, nothing sexual had happened—it all seemed innocent. The first time, Izuku had found it strange, but he relaxed when he realized it didn’t escalate beyond that.

He hadn’t tried making a fire until now. Why? It’s surprising, really, since that should’ve been the first thing to cross his mind. Why didn’t it? Good question. Maybe he was just too distracted by his whole situation.

Maybe the alpha was just taking a break. Maybe this was his chance. Still, he hadn’t yet tried convincing him to go—for his new objective... the beach, to try recovering his backpack. He feared the waves might have taken everything.

He was still eating bananas, but now he missed the blueberries he had found.

He had planned to stay only seven days on the island, and now... here he was. Funny how life works.

..........

Tomura’s tongue was in his hair again. As uncomfortable as it was, it was still an act of cleaning. It was hard to do it on oneself—some places were just impossible to reach. Maybe in the future, the omega would do it for him. In the tribe, omegas also cleaned their alphas; it was common among all genders. He had already noticed his omega was... different—but that didn’t diminish his attraction or the care he felt for him.
While the omega in his arms looked at some wilted flowers Tomura had brought from his last patrol, it was about time to throw them away.

Then he moved on to Izuku’s neck, purring softly. As always, he was hugging him from behind, arms wrapped tightly around his waist.
It felt good to perform the cleaning ritual—it was the purest care an alpha could offer. There were sacrifices: as his tongue passed, the bitter taste of dirt was ever present. Even so, he carried on. It was like purifying his partner.
He didn’t go further because of those strange skins, and his omega wanted to keep them on. To deepen the cleaning, they would have to come off.

Tomura was happy. He would have another day with his omega before needing to return to his duties. Despite his strength, he felt urgency to finish everything.
Alphas who crossed his path were either killed or fled—he’d earned a bit of a reputation, even if quietly. The island was immense, and word didn’t travel fast. Survivors didn’t like him enough to give any details.
It was like a vast kingdom where one didn’t matter as much as a large group. Still, among certain tribes, there was a warning: “Don’t go near the super dark forest.” No one really knew why.
The legend of the forest—the one that naturally existed before his influence—kept most at bay. But it didn’t stop lone alphas or betas from investigating, which helped him stay safe. If a tribe ever decided to send warriors to explore, Tomura wouldn’t be able to fight that many alone.

Until his omega interrupted him. Again.

— Grrrrr... — he growled when he saw Izuku trying to get up. But he was a determined omega.

He kind of liked that—but not too much.

— Mena! — he warned him to come back, but Izuku didn’t go far. He walked to the part of the cave where there was soft earth and called him over.

— Let me show you. I want to go here. — he said, while drawing an ocean and coastline in the dirt, childishly hoping Tomura would understand.

The alpha went to his omega, intending to drag him back to the cozy nest—at least, cozy in his opinion.

But then he saw the lines. It took him a moment, but he recognized the sea and the shores. In his tribe, there was no writing, no drawings—only spoken language.

Why would his omega want to go there? It was exposed to the sun, everything he avoided. No one liked the coast: it was too open, too vulnerable, and the sea was terrifying. Occasionally, invaders would come from the ocean—rare, but it happened. He’d seen it happen twice in ten years.

That was exactly where his omega had come from. But he was different—he hadn’t attacked like the others.
From where he was, in his territory, Tomura had seen from the mountains small groups far from his forest. They posed no real threat, so he ignored them.
Sure, he sometimes hunted people when he was bored, but it was troublesome, and he wouldn’t go after those groups unless they came near the forest—they feared it like most did.

He did remember, however, a floating object that had arrived from the sea. Again, he had seen it from afar. The people who disembarked from it had tried to hurt the omegas near the shore of those groups. Luckily, the alphas there reacted and killed all the invaders, looting the floating object afterward. That was why he hated the sea. Besides the violent waves, there were human dangers—rare, but real. He had to be prepared for everything.

Now, though, he had someone to protect.

Tomura grabbed Izuku’s arm—he had decided: they were not going to the sea. He pulled him back and nestled against him again, resuming the cleaning with his tongue. Now, however, he did it with restrained irritation over his companion’s absurd idea. He continued firmly while the omega whimpered, frustrated for not having convinced him.

..........

Damn! He had almost managed to convince him. He would try again—he wouldn’t give up. The alpha had listened to him before; he could listen again. Izuku only saw advantages in the idea. Frustrated, he closed his eyes, feeling his neck get drenched with saliva. He’d need to study that language more carefully later...
His skin actually felt better after being licked. Could that wild man’s saliva have moisturizing properties? After all, human saliva was acidic, which dried the skin. But his... well, albinism, scars, and the habit of scratching constantly certainly didn’t help maintain healthy skin, even with that saliva.

Maybe alphas had always had that ability in their saliva, but studies on human saliva were done in general—never distinguishing between genders. Or maybe it was a characteristic exclusive to the islanders... There were many possibilities.

Izuku ended up falling asleep to the massage on his neck.

Chapter Text

The alpha had left earlier that day. It had already been two weeks since Izuku’s attempt to communicate his desire to retrieve his belongings—he would try again, but not now. He ate a few more bananas.

— Uhhgr — he groaned at the nauseating taste. It was all he had.

He felt lonely when the alpha wasn’t around. Tomura had spent two days by his side—the day of the drawing and one more—just pleasing him, licking him, sleeping next to him. Sometimes, he would get up to eat from the carcass or to offer bananas directly to his mouth.

His absence made everything quieter. Izuku didn’t just feel alone—he was alone. And although he resisted admitting it, deep down, he knew that Tomura made him feel safe.

After eating, he went to take care of his hygiene.

Even so, he still felt filthy. The dust was constant. He undressed, standing naked without a second thought—taking advantage of the privacy of the empty cave. He went to the back of the cave and began scrubbing his clothes against the fine earth. They were stiff, brown with dirt and wear. The dust had embedded itself to the point that the thought of wearing them again made him nauseous.

Then, he scrubbed the dirt on himself—a crude attempt at cleanliness. Even that he already found repulsive. The sweat made the dust stick even more.

He still only went outside to relieve himself and to drink water. He would have to teach Tomura about bathing—he felt disgusting. How could the alpha not mind?

The answer was simple: Tomura had already demonstrated that bathing was an unknown act to him. For him, bad smells were ordinary, normal.

When we get used to the smell of something, we simply stop noticing—and Izuku realized that about himself. The odor of the cave, which at first had been nauseating, had become imperceptible over time.

He remembered when, as a child, he used to run from bath time—it was an interruption to his play. But now, it was all he wanted most. He finally realized that he had never truly valued that simple habit.

Now, the only option left was the dirt itself, but even that seemed to be losing its abrasive effect.

He dressed slowly, his eyes half-closed, his face marked by discomfort. He walked back to the nest of pelts in the center of the cave—a bit away from the entrance. It was a large cave, deep, but with a back wall.

He woke when the sky was already darkening, and Tomura still hadn’t returned. That was strange. Maybe he was just delayed—he tried to convince himself of that.

..........

After spending a sleepless night, he felt slightly calmer—but not less worried. Tomura still hadn’t come back. He usually returned in the middle or late afternoon, and now it was already the next day.

That had undoubtedly been his worst night on the island. He had thought the first two days, marked by insecurity and being abandoned on the beach, had been the hardest. He was deeply mistaken.

He couldn’t sleep. The sounds of the forest terrified him. Even the chirping of crickets and birds gave him chills. Maybe it was just his imagination, but he could have sworn he heard feline growls—not like an alpha’s growl, but like that of a jaguar… or a tiger.

Now, in the daylight, there was no sign of any predator. If that had been real, he’d already be dead, considering the sharp sense of smell those big cats had.

And then there was the cold. He felt vulnerable, like he was constantly at risk, about to be attacked from behind at any moment.

Had the alpha abandoned him? Had he realized Izuku was just a nuisance? Or… had he been killed?

He had watched the sunrise through the gaps in the leaves with silent hope. But nothing happened. No familiar sounds. No grrrr, no shuk. Absolute silence.

Not knowing what had happened was the worst part.

It was the perfect chance to run.

But… run where? Besides, that idea didn’t even make sense anymore. He needed the alpha. He needed him with an intensity that bordered on desperation.

..........

Another day passed, and Izuku was already desperate. He cried, lying down waiting for the alpha’s return. Sometimes, he would go near the entrance of the cave, eyes swollen, hoping to see Tomura emerging from the trees at any moment.

His desire to eat was completely gone.

..........

Two more days passed, and just like the previous ones, he spent the night awake—eyes swollen, red, with deep, dark circles. He didn’t eat; his stomach growled in protest, having stopped eating by the second day. He didn’t perform hygiene anymore, slipping into fits of insecurity. He dragged the nest further to the back of the cave, trying to protect himself from the cold—a task usually taken care of by Tomura’s warm body—and to feel safer. But it didn’t work. He curled up, face buried in the pelts, squeezing his eyes shut whenever he heard even slightly louder noises. It had now been three days since Tomura left.

He was afraid to go out to relieve himself. He still did, depending on the need, cleaning himself with leaves and running back to the den. But he wouldn’t go drink water—it was a considerable distance from the den, and he had always gone with the alpha.

By late afternoon, the nightmare of the night seemed ready to repeat itself, as on the previous nights, until he heard a sound: a growl and hurried, anxious steps. His body tensed, heart racing… until he recognized it.

It was his alpha!

..........

Tomura was returning home with the red berries—the most he could carry in his palms and some in his mouth—the yellow fruits, a small catch, and some more gifts. It was hard to walk with all of that in his arms. He hated being gone so long, but it was a step every alpha had to take.

As he neared home, he growled with irritation. He had gone too far. Besides doing what he always did, he had risked going even further, leaving his omega alone and the territory unprotected—without his scent—for a short but considerable time. He had even gone to the mountainous regions to get his special gift.

When his omega saw him coming in, he ran up to him with tear-filled eyes.

— NEVER DO THAT AGAIN! — Izuku screamed, desperate, throwing himself at the alpha, hugging him so tightly that Tomura accidentally dropped some of the things he carried.

He was surprised by that reaction. His omega missed him that much? Tomura hugged him back firmly, leading him to the nest. Izuku sat down, and Tomura placed the food in a corner, hiding the gifts behind his back. Izuku hadn’t noticed yet, not even the blueberries he had missed so much—there were flowers, as always. But this time, the simple stones had been replaced by his special gift.

Then, he revealed the presents. The flowers were quickly ignored in favor of the shiny object: an emerald, bright green, matching the lively color of Izuku’s hair and eyes. It was a large, rare stone, one Tomura had taken a long time to find. The trip there and back had been even more painful—he had to stay in the shadows as much as possible, and even then, sometimes the sun reached him. His skin was red, burned.

It reminded him of Izuku as soon as he saw it.

It was like an evolution of the courtship. Offering rare things was a way to show the depth of feelings—whether for family members or to indicate intentions of bonding, especially among alphas.

Izuku saw the jewel, and his eyes filled with even more tears. How could that man have left him alone for a “simple” jewel? But at the same time… Tomura had risked himself. For him. To give him that.

The alpha had gone those days without eating, which meant nothing to him. Looking to the side, he noticed Izuku hadn’t eaten much of the yellow fruits either.

That activated his alert: his omega hadn’t eaten during his absence?

Unacceptable.
He hurried to grab the red berries, making sure they were insect-free, while Izuku admired the beautiful gift in his hands, reflecting. Tomura wanted to know what his omega thought about it, unsure if it was good or bad—but Izuku seemed happy to see him. He had feared not finding Izuku upon returning, but he had trusted the natural protection and the lingering scent—he had been relieved when he smelled it again, making the return as rushed as possible.

So, his gift was worth it!

He rushed over and offered the berries to Izuku’s mouth. It broke the omega’s thoughts, and he began to eat slowly, his stomach fragile after going without food for so long, a bit happier to see the berries. He was satisfying his omega, and his courtship was working. Tomura purred loudly, while Izuku’s tears dried, and he ate, gazing deeply into Tomura’s red eyes, still holding the gift in his hands.

..........

Even after all that time together, Izuku had never even said his own name—assuming the wild man wouldn’t understand—but that day, he finally tried.

— My name is Izuku. Midoriya. — he said, sitting in the nest, while Tomura gnawed on a rabbit’s leg. It was still hard to watch, but more bearable. Tomura didn’t seem to understand his omega’s sounds at first.

Until Izuku pointed at himself and spoke slowly: — I-ZU-KU.

He understood—that was what his omega wanted to say.

Izuku? Was that his name? Different… even beautiful.
Tomura stopped and set the rabbit leg aside. He stared at Izuku attentively, thinking, trying to remember how to say his own name. He spent a few minutes in silence. By then, Izuku had already given up, thinking it wouldn’t work.

Until he heard:
— To-mu-raaar — with a slight growl at the end, due to his hoarse, deep voice, his lips curling slightly to reveal his teeth, even though the growl wasn’t part of the name, he had spoken it... while pointing to himself as well.

Izuku’s eyes widened. He spoke! His name!
So, he could learn… maybe he lived by a different, unknown language. It meant not all of his sounds were random.

What a powerful voice...

Chapter Text

Tomura woke up with sunlight on his face, his omega in his arms, nestled in the nest. He never imagined he would have to break one of his rules today—all because of the omega.
He purred, nose buried in the other's neck, sniffing like a needy little pup. Slowly, the omega began to wake too, opening those beautiful green eyes—his, and his alone.
Tomura felt the urge to stay there all day, like a reluctant worker who doesn't want to go to work. But he couldn’t afford that luxury. He licked the omega’s skin as usual—this time, not for cleanliness, but simply for affection.

He got up and was ready to leave. Izuku seemed thoughtful.

And so, he left.

..........

He was thinking about it—maybe he should try again to communicate his desire to retrieve his belongings. Now, he could call his alpha by name. That was good. It still felt surreal that the alpha could speak.

The alpha was gone, and along with him, so was that lingering insecurity. That quiet fear that he might take too long to return. He had slept so well the night Tomura came back... He felt safe and sound.
And now he had blueberries again, besides bananas. He almost smiled as the thought made his mouth water.

He needed to plan how to communicate his desire. The alpha knew his name now, but that didn’t mean he understood other words. He would have to draw again, this time with more space. The fine dirt inside the cave wouldn’t be enough; besides, he had to save it for his dry baths.

He would have to go outside. There was a lot of soil out there, slightly damp—not like the cave’s dry earth, protected from moisture.
Near the cave’s entrance, down the steep rocky path, he could draw there. Even though drawing on wet ground was… unpleasant, especially in his current situation.

He got excited just thinking about his backpack, his belongings. It had clothes too—just imagining the possibility of changing out of those filthy garments filled him with a burst of happiness. He could almost scream. And there was the knife, the mini torch, the books… and ah, his journal! He could draw Tomura in it, write down everything he had seen.

He was still lying down, nothing much to do, waiting for the alpha’s return—still with that little seed of fear that he might take too long again. He chose to think positively, imagining everything he could do with his backpack.

And maybe he could even teach Tomura things. Tomura… such a beautiful name, but it seemed to belong to another language. If the alpha could speak, then he had a language, right? Understanding the meaning of his sounds would be hard—but not impossible. He had been taught to read and write once, he could learn again—just in a different tongue.

He didn’t know what Tomura meant. He wanted to find out. Maybe there was a cultural meaning behind it. Despite being solitary, Tomura must have come from somewhere.

His thoughts were his main source of entertainment.

He heard Tomura returning. How long had he been thinking? He felt relieved the alpha was back—and regretted worrying so much, typical anxiety.

He was ready to execute the plan.

He waited for the alpha to drop his things and, in a bold move, got up and left. Tomura followed him, irritated by the daring act. The omega descended the rocky slope and began drawing again, this time bigger, in the wet earth. He drew the sea, the coastline… and a tiny backpack on the shore, with small dots around it.

..........

Once again, that idea—but this time, Tomura immediately understood what his omega wanted.

He had been ready to chase him for hours if necessary. The omega didn’t seem to be trying to escape—his scent was calm—so it had to be something else. Izuku stopped before the earth and drew again.

Deep down, Tomura liked this boldness. It meant he was strong. A warrior. He was proud of him.

He wasn’t like those submissive omegas who obeyed alphas in everything. But this boldness—this too irritated him. It was conflicting, pride and frustration. His instincts didn’t allow him to just let his omega do whatever he pleased, to take risks. Omegas, even determined ones, were still physically weaker, more fragile.

The omega wanted to go to the beach. That much he understood. But there was something different now… a smaller figure in the drawing. A... a…

Tomura didn’t know what that tiny figure was. But it was important to the smaller one.

Tomura stared for a moment.

— Grrrrr — he growled in warning, ordering him back.

He gently pulled Izuku back inside.

“The alpha didn’t understand again…” thought the omega, unaware of how wrong he was.

Tomura was wild—but he wasn’t stupid.

..........

He had the omega in his arms at night. Izuku was already fast asleep, breathing rhythmically. But Tomura remained wide awake, immersed in thought.

If he left now, he would have the advantage of darkness. His night vision allowed him to see clearly in the sleeping forest—a human trait, yes, but his was superior. Albinism had forced him to adapt. The beach was free from the sky’s burning ball. Still, sometimes he couldn’t completely escape the sun, which was why he hunted and marked territory early in the day, under the dense canopy’s protection.

He admired Izuku’s beautiful face, even in the shadows. He ran his fingers lovingly over the soft cheeks, lashes, and lips—his everything.

It was worth it.

If this mattered to Izuku, then it had to be done.

The omega needed to see that he was the ideal alpha: protector, provider—and someone who listened to his sweet voice. His Tomura.
He was strong. He would go.

..........

He left Izuku sleeping. The omega curled up without him. Tomura urinated all over the entrance, an extra layer of scent to keep predators and intruders away. Then he left. It was a considerable distance. He would reach it before Izuku woke up—it would probably take three hours walking, two if he ran. Even if Tomura didn’t know what hours were… you know.

And then there was the little dot with the other mini-dots. He had to find that, but it was hard when you didn’t know what you were looking for. He would be delayed, and the return would take even longer—especially the search. He remembered when he had taken the omega from the beach—he had noticed the object and the improvised nest where Izuku had been lying—but had ignored them.

Maybe that was it?

He arrived. He searched in circles, still in the dark, just before dawn, until he found it. It was covered in sand, worn, torn. He knew animals roamed the beach—leopards hunting sea turtles, for instance.

So he picked up the heavy object. He hesitated about whether to take that boring little nest too.

He took it, just in case. He wasn’t coming back here again, not like he did during patrols, since part of his territory brushed against the coastal forest.

..........

Izuku woke up in the middle of the night, cold. Tomura was gone. He jolted awake, heart pounding—why wasn’t he there? Anxiety gripped him again. He tried to sleep, managed only with difficulty, and decided not to panic prematurely.

When the sun was already high in the sky, Tomura returned—with surprises.

He was dragging something heavy by its strap… and the filthy old nest.

Izuku saw it. — My backpack! — he exclaimed, surprised and relieved. He had thought everything had been lost to the sea.

At last, his hardships were coming to an end. He hugged the alpha, just like that long-awaited day of his return. Happy and content, he could hear the alpha’s purr close to his ear.

He grabbed the backpack and the nest and carried them inside, followed closely by Tomura.

Chapter Text

Now Izuku could do many things—like roast the meat Tomura had brought. However, the very first thing he did after recovering his backpack was to check if the essential items were still inside. He sat down and began his inspection while Tomura watched with curiosity, interested in what his omega was doing.

Most of the items were probably still there—after all, the backpack had been zipped up, and he remembered storing it like that—but one could never be sure.

— "Okay, step by step..." — he murmured.

— "The knife is here, the torch too, my journal, clothes..." — He took out the books he had brought, but not all had survived the rain. Some pages were soaked, the ink smudged, now unreadable. A shame.

Two books had survived. Luckily, his journal and the one about plants and animals remained intact. The one on navigation, however, was completely lost. His hope of ever returning to civilization seemed gone. But by that point, Izuku had already accepted his fate, so it didn’t affect him as much as it would someone still clinging to their past life.

At least he had company — Izuku thought — until Tomura came closer and started sniffing the objects up close. The alpha wrinkled his nose, disgusted by the foul smell of the damp, worn paper, and without ceremony, smacked one of the soaked books, making water droplets and loose pages fly out.

— "Haha, I wanted to do that too," — Izuku commented, allowing himself a tired smile.

He thought he could at least use the ruined books as firewood. It would be a worthy purpose for something that no longer served—and would help conserve the torch, which needed to last as long as possible.

..........

Tomura was visibly disgusted by the smell of those things from inside the “big sack.” It was suspicious. He didn’t know what it was, or if it was dangerous—but for now, he decided to trust Izuku’s judgment.

The omega only decided to inspect the backpack again the next day. Perhaps out of fear of finding some gross, though not necessarily dangerous, animal like a crab or mollusk tucked among the items. But with Tomura there, he could handle it. The seashells were still in there too. Tomura, however, wasn’t impressed; he had seen plenty on the beach.

Fortunately, he had already hunted. It was the perfect opportunity to finally cook the meat.

This time, the prey was a baby deer. Izuku felt a pang of pity for the small creature, but reminded himself that humans needed to eat too. Tomura, on the other hand, was indifferent—though he maintained his usual diet of raw meat. He watched Izuku with hope: would the omega eat like him this time?

Izuku took the knife and began skinning the animal while Tomura observed with narrowed eyes, silently judging. What was his omega doing? He wasn’t sure, but he was curious to see where it would lead.

After removing the skin and fur, Izuku cut a piece of the tenderest meat—where there were fewer bones, which were harder to deal with. He chose the part with more fat. He needed it. He had lost a lot of weight living mostly on bananas; even with the recent addition of blueberries, he was still often hungry. Those were light foods, and his clothes had already begun to hang loose on his frame.

He gathered the damaged books—the “dead” ones—the torch, and a few stones. He stacked the books as makeshift fuel and began striking the stones to generate sparks.

Tomura watched every movement with absolute focus. He hadn’t connected the dots yet. He had never seen someone create fire by hand. His only memory of fire came from storms, when lightning struck trees and set them ablaze. But he had never learned to create a flame. He didn’t even know what it was called.

Until a small flame lit up after so much friction. Izuku struck close to the books, and the moisture didn’t interfere since it was minimal. Tomura’s red eyes widened with shock and curiosity.

He tried to smell it, but Izuku pushed his face away. Irritated, he insisted.

— "No."

Even so, he tried to touch it—until he felt a painful burn.

— "GRRRRRAAHHU!" — he roared in pain, pulling his hand back instantly. The fire had grown strong with the fuel. Izuku quickly grabbed his hand.

Tomura almost lunged at the fire to destroy it, but Izuku stepped in front of him. Did the omega not realize how dangerous that was?

The bright, dancing thing lit up the entire cave—it looked like a baby sun, like the one he had seen before. He thought it was the same. It hurt his red eyes slightly, so he avoided looking at it for too long. It was beautiful, warm around it, and didn’t burn the skin directly… so it was like Izuku—except for the danger.

Izuku took the sliced meat and placed it over the fire. He lowered the flame a bit first, so it wouldn’t burn, letting it cook slowly.

While Tomura kept his distance, Izuku checked his hand—it wasn’t badly burned, at least. The alpha had learned his lesson. Now, he’d need the same medicinal leaves from the time Tomura was injured.

But to get them, he would have to go out.

Once the meat was done, Izuku took it from the fire using the knife. He let it cool before eating, while Tomura watched, impressed. What had happened to his precious meat? It looked less bloody, the smell was different—actually good—and Izuku was devouring it joyfully. Was that why he had refused before? Because the meat had been bad?

Tomura sniffed again—this time the cooked meat—and Izuku offered:

— "Here, it’s tasty."

As with the bananas and blueberries, Tomura hesitated. Izuku ate calmly, savoring every bite. It had been so long since he had eaten meat… Finally, the alpha took a bite. Suddenly, the flavor hit him with full force. It was more delicious than any raw meat. Better than the meat without the baby sun!

He tried to take another bite. The chewing sound was good. But Izuku stopped him—there wasn’t much, and the omega needed it more. So Tomura returned to his bland meat. The little green one was surprised to see that this time, the alpha didn’t spit it out.

..........

They went out again, and Izuku had a new goal: to teach Tomura how to bathe. He needed it. As always, they went to the river to drink water, but this time Izuku brought clean clothes—eager for a bath. He’d repeat the process from before: the blindfold.

After they drank, Izuku blindfolded the alpha. As before, Tomura got irritated but recognized Izuku’s intent, even without fully understanding why. The omega then bathed while keeping one hand on Tomura, scrubbing every inch of his own body. He also washed the dirty clothes, caked with soil, and put on the clean ones.

Now it was Tomura’s turn.

Izuku removed the blindfold, and the alpha seemed relieved to see him well, though still visibly annoyed. When the omega tried to wet him again, Tomura growled impatiently:

— "Shuk! Shuk!" — he grumbled, frowning.

The omega decided to try a gentler method. Like with babies, singing lullabies could make bath time more pleasant. He knew this from Inko’s job—he sometimes helped care for the little ones in the houses she worked.

He began a random melody, soft and steady. Tomura, with water up to his knees, watched intently. He paused for a moment, suspicious. Izuku then took a cloth—the same one used as a blindfold—wet it, and approached the albino man.

Tomura growled again in warning, but Izuku wasn’t intimidated. He kept singing gently. Then, with delicate movements, he began wiping behind the alpha’s ears.

It was a gentle touch, almost affectionate, matching the whispered song. Slowly, Izuku felt Tomura’s tense body begin to relax. The alpha was gradually letting his guard down.

With the alpha calm, Izuku prepared for a silent pledge of trust. His next move would require it. Tomura’s neck, injured and blistered, needed the most care. He began gently, knowing it would sting.

As the burning sensation started, Tomura whimpered and tried to pull away, but Izuku stopped him with a calm gaze. Interrupting the moment now could ruin everything.

Patiently, Izuku wiped the alpha’s neck with the damp cloth, then moved up to his face. Before continuing, he gently closed Tomura’s eyes, which made him frown in protest. The marks on his face—also victims of albinism: sensitivity, itching, and lack of hygiene—needed attention.

Tomura looked like a baby being bathed, vulnerable, trusting despite not understanding. Izuku knew he couldn’t overdo it: the first time had to be peaceful, almost pleasant. If the alpha associated bathing with pain or discomfort, he would never allow it again.

He partially washed him, only the tips of his long white hair, and gently removed the dust from his body. The more sensitive parts would be for another day. When they left the water, the washed clothes were nearly dry. Gently, Izuku combed through Tomura’s damp hair with his fingers, despite his grumbling protests.

On their way back to the cave, they stopped to gather medicinal leaves. Izuku placed them in Tomura’s hand, who still seemed annoyed but didn’t resist. Once home, he arranged the makeshift bed, shook the fabric to remove the sand, and tried to lie down alone—but failed.

Tomura grabbed the nest and threw it aside. Then, he pulled Izuku into the center of the fur nest on the floor. He wasn’t sleeping apart tonight. Izuku laughed at the situation.

— "You’re lucky I didn’t have soap," — he joked lightly.

Tomura responded with a deep grunt, as if agreeing.

The next morning, the hair and skin Izuku had washed already looked visibly better.

Chapter Text

Izuku was anxious. His heat was approaching—just a few days away—and he feared how Tomura would react. He was afraid of the alpha’s response to the involuntary pheromones that would begin to emanate from him.

But it was inevitable. Run? Hide? Where to?

All he could do was wait… and hope that Tomura’s self-control would be stronger than his instincts.

..........

His omega was exuding a sweeter scent, a clear sign that heat was near. This time always left alphas restless. During a heat, an alpha received the answer to his efforts: he would either be accepted as a partner or rejected by the omega.

If rejected, he would need to double his efforts to win that specific omega—or give up and seek another, less demanding one.

But Tomura didn’t want another omega. It was that one, and only that one. He wouldn’t give up easily.

That day, Tomura was more agitated. Knowing this, he decided to go out on patrol—but not before showing Izuku some affection. He embraced the omega in the nest and began to nuzzle him lovingly, making Izuku laugh from the tickling, before heading out.

It was a Shimura tradition, during the approach of an alpha’s judgment, to leave omegas more alone—though always nearby. It was a way to give them space to think.

Tomura knew he would have to prolong the patrol and stay away from the den until Izuku’s heat fully manifested.

He could already imagine his pups; he purred softly.

Now, his “sniff sniff” was a way to cope with future longing, since he wouldn’t be able to get close to him.

Tomura’s own heat came every eight months and was balanced out by the omegas’ cycles.

He left with a heavy heart and brought back the usual.

..........

A few days later, Izuku was nearly in heat. Tomura remained away from the den, and he didn’t understand why. Maybe the alpha was smarter than he seemed. Could this be a sign of respect?

That thought made him happy—it meant, at least for now, he didn’t have to worry about what might happen.

Thinking it through, he realized they were slowly making progress. Tomura already accepted cooked meat and even waited for it—more than the raw meat—though he remained cautious with fire.

But the nights were getting colder. The alpha’s absence beside him was deeply felt, and Izuku worried about him, sleeping exposed to the elements.

That night, he took the old improvised bed and lay down in it again after a long time. The nest on the floor was too cold to sleep in alone.

..........

Tomura was outside, near the den’s entrance. The urge to go in and hold Izuku, to warm him with his body, was strong… but he held back. He knew he couldn’t give in. The omega needed time to think. He would only cross that threshold when the heat arrived—and would wait, patiently, for acceptance… or, in the worst case, rejection.

He felt cold without Izuku’s warmth beside him. The emptiness was almost physical.

If accepted, the omega would let him in, inviting him into his territory, his nest, his body. But if rejected, he would have to wait outside until the heat passed completely—then start the courtship again, with more effort, more care, more devotion.

That’s how it worked for worthy alphas. Almost like a ritual. A test of self-control.

An alpha who didn’t respect his omega’s will wasn’t worthy of a bond. He was just a coward disguised as a predator.

In some tribes, omegas were treated like objects, even if the culture was harsh.

..........

The day arrived.
Izuku felt hot, his scent intoxicating. He was more fertile than usual—but surprisingly, the alpha didn’t come. Better that way.

Meanwhile, Tomura struggled outside. He didn’t know whether to go in now or wait a bit longer. But the scent was delicious, perfect for starting a family. Still, it was strong… he wanted to go in and make pups, but giving in to impulses could be dangerous. The first rule of survival: your instincts can get you killed.

He waited. Izuku was curled up. Tomura peeked in to check if he was okay and then decided to try.

As soon as he entered, Izuku looked at him with discomfort. His scent turned slightly sour.

In that moment, Tomura knew: he would have to try harder.

He was shaken, irritated, frustrated—he mutilated a little rabbit with his teeth—but remained determined. Izuku wouldn’t shake him off so easily. He wouldn’t stop belonging to him. He was his.

Tomura stayed outside the den for another three days after that. When he returned, he reflected on what needed to change. He thought deeply throughout the night. And now, Izuku was pressed up against him again.

He remembered everything he had done for the omega… but it wasn’t enough.

Now it was clear: the omega had rejected him because of his refusal to get wet—that is, the bath. Maybe that was it.

..........

When he saw the alpha enter and leave, Izuku felt a flicker of fear.
An alpha from his own society would have taken advantage of that vulnerable moment… but Tomura was different.
He was attractive, caring—but the time wasn’t right. Even if his omega instincts begged him to give in to the heat, he wouldn’t allow it.

He wouldn’t let it overwhelm him.
He didn’t even know what he felt for the alpha, exactly—he had never felt this for anyone.
Was it desire? Passion? Or something deeper?

Maybe he should’ve brought romance novels too… but who expects to live one in the jungle?

Now he was curled up against Tomura, conflicted. His hands rested on the alpha’s strong forearms, and the snow-white skin was beautiful—despite the skin issues he had.

When Izuku had to leave the cave during those three days, the alpha noticed—and followed from a great distance, just to make sure the omega was safe.

Even then, he respected his limits.

..........

Their relationship stayed the same after the rejection—or rather, improved.
Tomura was now willing to change, even after all the gifts he had brought. And that was a good sign.

There were still behaviors he needed to work on, even if it hurt and went against his preferences.

..........

Tomura heard a growl coming from the woods in the dead of night. A predator was near.

Izuku woke with a start, at the sound of snarls and screams in the middle of the night. He realized Tomura wasn’t beside him. He got up in a rush, gripped by panic, and stumbled toward the den’s entrance. The dim light made it hard to see, but there was no doubt: the alpha was fighting. The sharp scent of blood hit his nostrils.

His heart raced, overwhelmed with fear of what might have happened.

Tomura was locked in a brutal fight with a mountain lion—a puma.
Wounded by scratches and bites, he was deploying his favorite technique: the death bite.

In ten years, he had only faced three of those. Most fled at the sound of his piercing screams, which hurt even predators’ ears.
Though pumas were smaller and more agile than leopards, they were weaker—and that made all the difference.

Looked like he’d have to heal his alpha again.
And now, he was more afraid of the forest than ever before.

Chapter Text

Months had passed. Some things had changed during that time. Winter had arrived, bringing cold and snow. Many habits had to be adapted: making fire, for example, became more difficult. The spark was slow to appear, but with effort, Izuku managed. Fire was now more than just comfort — it provided extra warmth and kept predators away.

Izuku had to care for Tomura after the fight with the puma. It seemed the alpha liked being taken care of… he became docile, quiet, almost purring. It made him even more endearing in Izuku’s eyes.

Hunting had also become harder. The deer were hidden, almost invisible in the white landscape. But Shigaraki was persistent. Nothing he couldn’t handle, though it took more effort.
He also sealed the entrance further with mud, to block the wind partially.

The bigger issue came as winter deepened: the water began to freeze. Bathing was almost impossible now, but Izuku saw it as a challenge. Poor Tomura… he would still have to bathe.

Tomura was out hunting now. Right after marking the territory with his scent and bringing the usual gifts for his omega, the deer would hide in the brush. Because of the winter, the sun stayed hidden behind clouds, and the ground was covered in white. It was his favorite season.

His albinism gave him an advantage in winter — he was like a ghost in the landscape. Hunting was easier in this season, though finding prey required more focus.

His target was grazing in the forest, accompanied by a fawn. Tomura was very close, yet hadn’t been fully detected. The female's ears picked up his sounds, but not his form — he remained crouched in the snow, invisible. He only had to avoid the green patches.

All the female and her fawn could see were two floating red dots — his eyes — and some pinkish patches — his exposed scars. To an unknowing observer, they looked like fragments of nothingness suspended in white.

Tomura watched intently. He fixed his gaze for a few seconds on the tiny fawn. It was cute. Finding prey cute was strange… but true. Like saying food looked beautiful.

For a moment, he caught himself wondering: would he be the father of Izuku’s pups someday? Most likely, yes.

The deer, like other herbivores, faced a real crisis during winter. Beyond the biting cold, there was constant hunger. The thick snow covered almost all the greenery, making it hard to find food. They were forced to travel long distances through the tall woods, desperately searching for exposed grass patches.

That explained why the poor doe and her fawn hadn’t fled at the minimal involuntary noises the albino human’s body made. It was a calculated risk. Fleeing could mean starvation. Staying could mean death.

The fawn looked too young — still nursing, surely. The mother, in turn, needed to eat to produce enough milk and keep the baby alive. It was a cruel cycle of nature — giving everything to protect the fragile.

Tomura was suffering too. The winter’s biting cold made his lips crack more and more. His already sensitive skin burned under the freezing wind. His only heat source was the little fat he still kept in his body — but he endured. He was a hunter. He was an alpha. His breath came out in steam.
And he had to return quickly, to the warmth. To Izuku.

He leapt, landing precisely on the mother deer. The impact was dry, violent. The fawn jumped in fright but didn’t run far — its short, trembling steps barely took it out of danger. That baby was doomed. If it didn’t find another lactating female, it would starve… or freeze. All paths were fatal — and fast.

Tomura dragged the carcass back home as fast as he could. The fawn tried to follow its mother, stumbling, calling out silently with wide eyes. The alpha felt pity — it was helpless. Trying to follow a mother who now left a trail of blood in the snow.

Izuku would never let him do this. If he were there, he’d surely stop the scene.

Tomura moved on… but the fawn kept following.

He growled, trying to scare it off.

The little one hesitated… and fled. If Tomura were followed, he could attract predators, so he didn’t care.

.............

With the fire protecting them from the cold and roasting the meat, things were great, and the alpha clung to the omega, but Izuku didn’t seem satisfied.
That’s why, once the snow stopped, the omega dragged him outside, and Tomura didn’t know why.

Tomura passed his hand over the snow and uncovered a large plant — life persisting. Izuku's eyes widened.

— “Look at that, aromatic herbs,” Izuku said.

He had to find another way to bathe, since the water was far too cold. He would rub the leaves over his body to smell nice. In other words — the bath continued to haunt Tomura.

But he had caused this himself — he was the one who found the plants. He guessed the omega wanted them, since he spent hours looking at those things with plant pictures.
He knew how to find them.

As for the water, Tomura only broke the ice on the surface to drink. The omega had tried to use it to bathe, but it was freezing — he’d fall ill. Drinking it was already painful enough.
One thing the alpha didn’t like about winter was how it hindered his courtship. It seemed the flowers and colorful things didn’t like the cold, so his gifts were reduced to pretty stones and the meat he brought for the omega to use the “sun baby” on.

After the emerald, he had to go back to regular stones. Finding more emeralds would take too long, and Izuku didn’t seem to like his absence. So he’d do what the omega wanted and keep courting as best as he could.
But the most important offering in winter was warmth.

Besides that, the alpha did something peculiar at night. Upon seeing the improvised bed (which resembled a futon) used by Izuku, he started sleeping in it with him every night.
It was a bit embarrassing, and their physical contact grew closer, but it was incredibly warm, and the bed’s tight space made it even warmer.

Izuku suffered in winter with his thin clothing — he’d prepared for a tropical climate. He avoided going out, but sometimes it was necessary.

The alpha purred so much in the warmth that one day Izuku realized — he himself had purred too. He was so surprised. He had never made that sound before and grew curious. It surely meant contentment and pleasure.

Tomura felt different since starting the crispy meat diet. He felt stronger and didn’t feel nauseous as often (it was surprising he was alive, but everyone in his tribe ate raw meat), and the flavor was very good.

Back in the cave, Izuku began undressing and used the same method of blindfolding Tomura. He rubbed the leaves over his body — and also on his teeth.
Whenever he bathed with water, he cleaned them too. With leaves, it was harder. Back when he took “earth baths,” it hadn’t even been possible… which made everything awful.

This time, the clothes couldn’t be washed — but Tomura wouldn’t escape.
Once done with his improvised hygiene, Izuku went straight to the alpha.

Like during water baths, the alpha was reluctant at first — until Izuku started singing softly and went gently. He managed to rub the leaves all over him, and soon Tomura smelled nice.
But the final challenge remained: the teeth.

With water, Izuku hadn’t insisted as much after the first time. But now, with leaves, the process was less harsh, and he wanted to finish quickly — the wind coming through the cave entrance was freezing.

He gently pulled Tomura’s lips upward, going slowly. Whenever an involuntary reflex threatened to surface, Izuku paused and waited patiently. He repeated the process delicately. It was a new victory: Tomura was cooperating too.

He finally managed to clean the alpha’s sharp teeth. He dressed quickly, his fingers frozen, but his heart warm.
And so they continued — one day at a time — facing the winter together.

Chapter Text

The Shimura tribe — also known as Shigaraki — was one of the oldest on the island of Valmora. It shared territory with other large tribes: the Khatari, Uvalek, Varnok, Thamuur, Saanvel, Elyari, and Alahmari. In addition to these, there were smaller groups and individuals who did not belong to any tribal lineage.

Each of these tribes was hostile to the others, maintaining alliances only temporarily and always out of momentary interest. As soon as the benefit was achieved, the agreements dissolved, and hostility returned. However, such alliances were rare events, formed only in cases of extreme necessity — and only if both parties accepted the terms.

Tomura remembered little of his tribe of origin, or rather, he remembered little of the people; they did not matter to him.

...........

Kotaro looked at his newborn pup, still crying, covered in the fluids of birth, clinging to the wet skin of the omega mother.

But something about this baby seemed… wrong. His skin and hair were white as snow, a paleness that clashed with everything Kotaro knew. When the little one opened his eyes, what he saw made his stomach churn — red eyes, intense as fresh blood, stared at the alpha father with a vacant but provocative expression.

Hana’s first reaction upon seeing her brother was to slap him, making him cry.

The other members of the tribe also did not react with welcome. The white skin and hair of the pup had never been seen before. Since no one knew what it was, they came to see it as a bad omen.

— Theral nuh esh drav’al nurekk! (Your pup is a nature’s aberration!) — said one of the family’s acquaintances.

The language spoken by the Shimura tribe was Shiguan.

— Kànu theral vek arak shuun, vâresh tal’nek. (This pup may bring misfortune to us. Get rid of him.) — At that moment, the group leader decided Tomura’s fate.

Even so, they cared for little Shigaraki until he stopped nursing and reached five years old. During that time, they never fully taught him the native language — apart from his own name — and he only spoke six words:

Mena → "Stay," "Wait," or "Protection"
Grah → "Hunt"
Shuk → "No" or "Forbidden"
Drek → "Pain"
Soru → "Nest," "Home," or "Intimate protection"
Gurah → "Danger" or "Attention"

But he preferred to use his own nonverbal language, through grunts and growls.

Instead of being killed, his mother begged for mercy, and he was not killed at five years old — but he remained isolated behind a barrier of logs at the borders. From there, he watched everything and listened, but stayed alone. He understood his own language, but did not speak it fully.

In the first days, he looked for his mother, but she never came. The light of the giant ball in the sky hurt him — his albinism was a disadvantage under the light. The Shigaraki’s homeland was very hot; everyone was naked, which was normal, brought agility, and less heat, unlike some other tribes who wore furs.

He learned some things just by observing and listening from afar; others he found irrelevant and didn’t pay attention to.

No one cared about him. He learned to hunt alone at seven years old.

There was a small stream in his area, and when he was found by others, he was beaten.

His father, Tomura, never learned the name of his father, nor of his sister or mother. It seemed he hated him. And when they met, Tomura was almost killed every time.

Until he turned eight, when he began to nurture a mortal hatred for his own tribe.

This hatred intensified when he reached sexual maturity at thirteen years old (he had manifested as an alpha at five).

Then, he distracted himself with hunting and training. He decided to explore the area and walked a lot. At fifteen, Tomura committed an atrocity. He was much stronger and more muscular; his solitude had shaped him to be independent. His teeth, nails, and hair had grown, he was wilder than other alphas naturally, hunted his prey cruelly, ate raw meat, as others also did.

Despite his albinism, he was an indirect example among alphas. He had a reputation for being aggressive, dangerous, with behavior outside the norms.
It was a rule in his tribe that the alpha should go after the omegas — so they did not approach him, and he did not approach any. And that was fine.

He had developed a skill: due to his adaptability to darkness, his night vision became sharper. (The forest where Tomura lives in the present was dark precisely to hide him from light, although at times he needed to expose himself to the sun — as in the fight against the old alpha.)

Then, one night, he killed the entire Shimura tribe. Darkness was his ally. They didn’t even know what hit them.
He had his revenge.
The tribe was nearly extinct, except for him.

Of course, Tomura was stronger than the others, of course he was special, different.

And of course, the disdain was cultural, as the rules preached destruction as renewal. He observed all that and replicated the behavior, killing his prey in the worst possible way.

The tribe was almost extinct — only he remained.

Of course, Tomura was stronger than the others. Of course he was special, different.

And of course, the disdain was cultural, as the rules preached destruction as a form of renewal. He observed all that and began to replicate the behavior, killing his prey in the worst possible way.

.........

He burned himself a lot crossing the open fields — his skin turned red from burns, his eyes burned as if on fire. It was like that until he found that extremely dark forest.

He had heard of the place, there was a legend about it, but he paid no attention.
It was perfect for him.

There was a variety of prey, clean rivers, and above all, darkness. Tomura focused on finding a den. When he found one, he marked it as his — the cave and all the surrounding territory, about three kilometers wide, were vast.

He marked it as all alphas did: spreading urine and his scent around the den.

There, he stayed for ten years. Completely alone.

He had gained a lot of experience during that time, learning everything on his own, in practice; hunting, fighting, and solitude were his teachers.

That space, entirely his, was perfect for a solitary alpha.

.........

He found the omega asleep on the beach in his area. By the smell, it was nighttime, so it was safe to leave the forest; he had already followed the same omega during the day. It was cute and fertile, with strange objects nearby and in a very odd nest.

He felt an impulse and knew the omega should be his. For the first time, he saw an omega as a potential partner; perhaps it was destiny. The little one seemed different. He felt attracted to him — that’s how alphas felt.

It was the best choice of his life to bring the omega to his home! He could form a family that would accept him — perhaps even a new tribe. The omega seemed to like him. So far, he had not rejected his investment; despite the initial rejection during the heat, Izuku was responding well.

Chapter Text

Years passed, he didn’t know if it was two or three; he kept living on the island as he could, all with Tomura.

............

He didn’t understand his feelings. He felt agitation in his stomach when seeing that cute face looking at him, a strange tingling, and he wanted to impress him — and Tomura had never cared about anyone’s opinion since he was eight. But now, he wanted to protect him. He felt the mating instinct when sensing the scent of fertility… and he had never wanted to protect anyone before, he would feel sad if Izuku was sad, and happy if he was happy, happy when he was with him, which was strange considering his history of solitude. He liked being alone, but now there was a desire to form a lasting bond, a family; this went beyond attraction. He had felt it before, but now it was very strong over time, he feared the feeling would explode from his chest — I tell you this because Tomura himself would not know how to explain it.

Could this be love?

Even if the omega hadn’t admitted it, his body said otherwise. Tomura noticed the behaviors, the way his presence was no longer avoided but expected. There was something there, growing. And it was already big.

The omega hadn’t surrendered to him yet, but he wouldn’t give up; his feelings for him were now beyond admiration. He admired Izuku, a strong omega, and he was his.

He had been rejected in previous heats, but he wouldn’t give up, despite growing frustration. For Izuku.
Before it was desire, when he caught the omega on the beach, it evolved, and now his heart belonged to the omega.

And so they lived together.

............

Izuku didn’t know what to think. He had developed feelings for a wild man — now it was official. Many things had changed.
Like his feelings. He couldn’t describe them.
The alpha seemed like the ideal partner, not just by instinct, but because Izuku had fallen in love.
He was cared for by him… and also cared for him. But he didn’t know what to do with that feeling. How to reciprocate to a man of such a different culture?
Even his nudity had become “normal,” though he still respected it.
He had lost track of time. He didn’t even notice the days passing. Tomura was like a sun in his dark life.

Now, Izuku was learning so much from the alpha… how to use the wind to his advantage — standing against the wind would spread his scent — and he also taught him. He taught him to bathe more naturally, for example. Even the alpha had tried to roast meat the way he did. But it didn’t work. He tried to imitate the omega; it seemed right… until the meat turned black.
All without dialogue, just drawings. Now, Tomura drew on the cave walls.
They looked like prehistoric paintings from history books.

On the tenth attempt, it even turned out good. He offered the meat with great pride, chest puffed out. The omega almost cried with emotion.

He taught Tomura to draw, and Tomura shared many things through illustrations.
Like his old tribe — he drew several humans grouped with a circle around them, and outside it, a little boy. The red eyes looked slightly sad in the drawing. He used earth or blood to draw.

He also recounted some life experiences, like hunts and battles. But the most touching was… their story.

He drew a man, and another lying by the seaside. Then, the two together inside a circle — the bigger human and the smaller one.

It was so moving… he cried a lot that day.
The alpha didn’t know why, he just passed his fingers under his green eyes, as consolation.

Izuku also drew houses, boats, and alphas with angry faces. Tomura growled looking at them — he understood they were something negative.
He also drew his mother… he missed her. She was a slightly chubbier stick figure beside him, but Tomura didn’t understand exactly who it was.

He also didn’t understand the concept of houses, boats, and structures.

There were so many things Izuku wanted to discover… like the alpha’s saliva, and his culture. From the drawings, it was clear that Tomura had belonged to a tribe. That was fascinating. It would be difficult to understand everything without words, but the simple fact that there was real communication was already surreal.

There was no material to study certain aspects, like the alpha’s saliva or the purring — which he himself noticed — and without books, he lacked a foundation. Still, he built theories.

Some sounds the alpha made seemed to have meaning. “Shuk,” for example, always appeared in negative situations. Perhaps it was a way of saying “no.” “Mena” seemed to appear in moments that required patience.

Of course, they could be just random sounds. But Izuku believed they weren’t. The phonetics showed patterns that resembled a real language — not just growls or grunts, like the ones Tomura usually used.

There was also “gurah” for danger; Tomura used the shouts, rarely saying that sound.

Tomura also had doubts about Izuku’s language. Those sounds and drawn things were strange, bizarre, almost alien. The omega’s speech was too complex. Sometimes, the alpha accompanied him in his readings, and Izuku tried to teach a word or two, but the only ones Tomura could pronounce somewhat naturally were “eat” and “sleep.” He probably didn’t know that the alpha knew the meaning of the words, but probably did. Still with difficulty, but it was a start — and a good one.

Izuku, for his part, found himself doing peculiar things: smelling more often, purring involuntarily… Maybe his body was awakening primitive instincts. Sometimes, without realizing, he also imitated Tomura’s vocalizations.

That was what happened when entering a new world — adaptation was inevitable.

It was something he really wanted to study: the awakening of instinctive behaviors. And then the doubt arose — do we all carry a bit of our ancestors within us, but it’s impossible to perceive until necessary? There was the issue of lack of resources, unfortunately.

His strongest theories revolved around this: dormant behaviors. Or, in a more out-of-the-box hypothesis, maybe time worked differently on that island. Still, he preferred to bet on the first theory.

The omega had to deal with the poor animals Tomura hunted. Over time, he learned that certain things were necessary — the death of one is the life of another. Everything is born, grows, and dies, and there’s no changing that.

Still, he preferred fruits. Although roasted meat was good, when winter passed, he could eat them again.

Now, alpha and omega were together, in the same improvised bed. Even though winter had already ended, it had become a habit to sleep there, instead of the nest on the ground. They only left the bed during summer, when the heat required some distance. But Tomura remained clingy, like a kitten, though now he was more fragrant; the environment kept the same scent due to the alpha’s territorial behavior.

Chapter Text

There were many fun moments during that time together. Some examples include the day they built a nest side by side, gathering dry leaves, furs, and old fabrics — Tomura carried everything seriously, as if it were a sacred task, while Izuku smiled with a warmed heart. Or the day when Izuku, with patience and gentle fingers, braided the alpha’s white strands, who, despite his grumpy face, let it happen without resistance. There was also the moment when he drew Tomura’s face on the cave wall, with charcoal and care… and the alpha spent long minutes analyzing the drawing, pointing at himself with a confused expression, as if asking: is that me?

They were small moments, but they held a quiet sweetness. A love in growth, still without words, but full of meaning.

.............

It was an ordinary day. Izuku was bored, until a terrible — and fun — idea popped into his head. His eyes shone mischievously as he observed Tomura’s white hair, long, loose, and… defenseless. Perfect for a good hairstyle.

Sitting with a book in hand, Izuku pretended to be occupied, while the alpha lazily gnawed on a hunting bone. The evening cast a soft light over the cave, and Tomura had just returned. He was quieter than usual, with a tired air. Perhaps that was exactly why Izuku thought he needed a little fun.

The omega’s expression betrayed the mischief about to unfold.

He rose silently — at least in his own perception — and approached cautiously. But Tomura had already noticed him, tracking every step with attentive ears. Still, he decided to play along, pretending to be distracted. His red eyes stayed fixed on some point ahead, deliberately ignoring his partner.

Until Izuku suddenly jumped, wrapping his arms around the alpha’s neck from behind, with a mischievous smile. The red eyes turned upward, meeting the omega’s face with a playful glint, and a soft, low purr escaped his chest, grave yet gentle, like contained contentment.

Izuku then whispered, almost like a playful threat:

— Stay still, Tomura… today you’ll get a hairstyle worthy of a forest king.

The alpha just closed his eyes for a second and sighed, surrendered. Perhaps he was too tired to resist. Or maybe… he liked being pampered that way.

Izuku was ready to put the plan into action.

He began braiding, unsure whether to make small braids or braid all of it — he chose the latter.
He was eager to see Tomura’s astonished face.

The result was… eeerrr… different, but not completely ugly. There was nothing to tie it at the end, and brushing it with hands didn’t produce great results. In the end, it became a wild braid.
Tomura grabbed the hair in his hands and seemed indignant, frowning — what had the omega done to his beloved hair? Izuku laughed sincerely. Definitely, Izuku wasn’t good with hair — his own was untamable.

............

Tomura had the brilliant idea of making a new nest. If his family grew in the future, he needed a bigger space, right?

He called the omega, with his hands resting on the ground, and with one arm gently pulled Izuku’s beautiful hands out of the den.
Tomura didn’t always walk upright all the time, only about half the time. Izuku walked on two legs all the time. The alpha sometimes rested his hands on the ground — which increased his agility, especially during hunting.

The albino man guided his omega through the forest. They found grass, leaves, and some stones. However, Izuku didn’t seem satisfied with the items. They returned to the den, where there was meat.
Tomura tried to communicate his desire for a new nest through drawing — and the omega understood. Izuku thought it better if the nest were made only of furs. And so he “answered.”

The alpha went into a hunting frenzy, seeking large prey with plenty of fur. Izuku was responsible for cutting the hides and washing them with water, while Tomura removed the fat, leaving the furs to dry in the sun — so they hardened, and that’s roughly how leather was made.
They also enjoyed the meat for a roasted feast.

They gathered many furs, and the nest became thick from so much accumulated fur. Still, Izuku’s improvised bed was the most used in winter, where they warmed themselves together in that small, cozy space. The larger nest was for other seasons — also warm, but more spacious.

Izuku covered himself with the furs, and Tomura ended up adopting the habit of covering himself with them too, not so much for cold protection, but to embrace the omega. In the cozy winter bed, they even added more furs on top to maintain warmth.

The previously used fur was old and was discarded.

............

Izuku was being licked, as always. Even if Tomura accepted the bath, some habits never changed; he would always bathe Izuku his way. And Izuku liked it. The alpha never stopped his courtship: tongue cleaning, small gestures of affection, gifts — they were snug like two little kittens.

Until his hand reached Tomura’s white hair. He didn’t know exactly why, but the alpha seemed like a cute, needy little dog being licked, perhaps that was it.
His hair was too beautiful, even messy; the white color was vibrant, the alpha was entirely gorgeous.
Tomura froze, eyes wide, but when the touch intensified, he relaxed and closed his red eyes, purring, enjoying the affection.

— Ooohhh — Izuku made the universal sound of cuteness. His alpha was rough, but very cute.

...........

Tomura was still indignant about his face on the wall, drawn by Izuku, with a ♡. He didn’t know what the symbol meant, but it was good, according to the omega.

— I don’t draw that badly, do I? — said Izuku, seeing the man’s confused expression.

Then, the omega approached and hugged the alpha, while looking at his face, tracing the “outline” of his face; the alpha felt his heart race, a strong and fast beat. He didn’t know what it was, but it was okay.

Chapter Text

Izuku was feeling hot. His heat was approaching, and, as always, Tomura stayed outside the nest after bringing plenty of food for the omega — until the heat passed. He remained in the open, regardless of rain or sun; even though he hated getting wet, that alpha definitely had an ironclad immune system. He didn’t get sick, especially since he used to eat raw meat like an animal.

Izuku’s instincts were on edge. So were his emotions. He felt that this particular heat would be different. As if something were about to change — as if it were a turning point.

In the nest, he was being held by Tomura, who looked at him with affection.
The care and tenderness had been accumulating; it was as if it would never happen if not now.

..............

Did he really have to go? — he thought, watching Tomura leave. As always, as soon as the heat began, the alpha would come to the den’s entrance, watch Izuku for a few seconds… and then leave, staying outside until it all passed.
Izuku never really knew why that happened, the observing and leaving.

But, this time, he wanted him to stay.
As if his instincts were pleading for a deeper bond.
Maybe even have offspring…
Izuku mentally scolded himself for thinking that — but did he really want it?

Maybe it was just the instincts.
Or maybe… it was him. His feelings were too complex to describe precisely.
He turned to the other side, now alone, inhaling the scent of the alpha that filled the nest. It was better now — not exactly perfumed, but clean, with more frequent hygiene.
His fur bristled.

He curled up, waiting for what was to come.

The heat came in full force.
His body burned with heat, tremors, and a sharp sensitivity.
He was fertile.
And, involuntarily, between trembling sighs… he whispered Tomura’s name.

..............

Tomura was outside, as he always did during the omega’s heat. Sitting under the dark sky, his body wet from the fine rain that had started to fall, he reflected. It had been so long since he began courting him. Years. And yet, in every heat, he was rejected.

He didn’t understand why.

Before, he had felt anger. A raw fury that burned inside. Now, only frustration remained — and an uncomfortable emptiness. He did everything as he had seen. Offered fresh meat, built comfortable nests, brought shiny objects that Izuku seemed to like, even tolerated that strange habit of getting wet together, despite hating the feeling of water on his bare skin.

Nothing changed.

He recalled that, in his old tribe, alphas rarely waited more than a few months to be accepted as partners. He… had been in this silent wait for years. Sometimes he wondered if something was wrong with Izuku. Was he really a defective omega?

Thinking about it left him bitter. But it was impossible to ignore how different he was. Strange habits, cooked meat, colorful things he liked to eat, the artificial skin covering his body, that incomprehensible speech — like a creature from another world. He seemed cursed by luck, as if nature itself had forgotten him.
(Always in heat, the alpha hunted a lot to respect Izuku, had excellent self-control, a surprising skill.)

And when the heat finally arrived, Tomura had a dangerous thought. For a moment, he considered giving up.
For another… he thought about claiming what was his. Taking it by force. It was his right, wasn’t it?

But he hated himself for thinking that.
Then his ears, sensitive to the slightest sound, caught a muffled whisper coming from the den.

— Tomura…

He blinked. Had he heard correctly?
No, it couldn’t be. Maybe he was only hearing what he wanted to hear, a daydream shaped by his desires. But… what if it wasn’t?

He rose, alert. The scent in the air was denser.
And, for the first time in many cycles, his heart hesitated between hope and fear.
Hesitant, Tomura approached the den’s entrance, as he always did. He leaned slightly and peeked.

Izuku was there, curled up as before, his body folded into itself, fur bristled. A comforting warmth radiated from the nest, mixed with the sweet and intoxicating scent of the omega in heat. That familiar aroma hit him like a warm wave, momentarily dizzying him.
Nothing seemed different. Just another heat. Like so many others.
He was about to turn away, resigned, when he heard again:

— Tomura…

He froze. His heart skipped a beat.

Was it real? Or just another echo of his hope?
He stood still, torn between entering or retreating. Until something broke his indecision: Izuku slowly turned his head in his direction.
His green eyes were wet, dilated, pleading.
Blushed cheeks spoke more than words ever could.

— Tomura… — he repeated, his voice trembling and soft like the touch of wind through leaves.

But one thing was certain: Izuku was calling him.

And this time, it wasn’t to leave.

.............

Izuku knew what he was doing. It was time to consummate the feeling that had grown over time, patiently.

Tomura, still wary, his red eyes shining in a mix of confusion and childlike hope, approached in tiny steps, as if unsure whether he really could be there.
He stopped beside Izuku, now visibly dizzy — the scent was too strong, intoxicating. He crouched, and his chest seemed ready to burst. His eyes burned.

He reached out and touched Izuku, very lightly, as if fearing it was all just an illusion.
The omega felt it was a new beginning, almost abandoning his old identity, yet still remaining Izuku.

Izuku, feeling the touch, did not recoil. Instead, he raised his hand and placed it over the alpha’s, confirming his permission.
He felt grateful. Deeply grateful. Another alpha could have abandoned him, or worse, taken him by force.
But not his.
He felt stronger, yet vulnerable at the same time, it was strange; he was trusting, and that trust hadn’t come overnight, it had taken years together. Tomura cared for him, didn’t force him, protected him — he was a good partner. He trusted Tomura to be gentle with him.

Tomura was precious. A rare albino gem.

.............

Tomura was crying, stubborn tears he didn’t want to shed since it could attract bad things, which was considered unlucky by the tribe, while clutching his own hair as if it were unbelievable. He was being comforted by Izuku, who hugged him tightly, now partially seated.
The omega was ready to surrender, and soon they would be official partners — a bond for life, permanent. Soon, they would also have offspring, like a happy family.
He would care for the omega, the pups… he could almost feel that future.
Would the pups have dark green or white hair?
And their eyes, would they be red or green?
Would they be albino, or luckier in the sun, inheriting Izuku’s freckled skin?
In any case, they would have offspring, alpha and omega.
After that, Izuku lay face down, let his furs be removed, and surrendered. Now he was complete.

The alpha hugged his omega, fingers tracing the marking left on the night, right at the nape. Their bodies ached.
— prrrrrrr —
He protected Izuku from the cold, in the nest, his hair cascading over the omega, his head beneath it.
He was finally happy.
— Soru — he said with a half-smile.

Chapter Text

Izuku felt nauseous, biting into a piece of roasted meat while looking at Tomura.

His life as an official partner was going great; Tomura cared for him with even more dedication, and they were closer than ever. The alpha had not lessened his care or courting, and that made him feel safe and loved.
However, something was starting to worry Izuku. He felt somewhat distracted, as if his mind were wandering, especially after three months since their bonding. Something was different, but he couldn’t understand what it was.
Now the signs were stronger. Before, they had been so subtle.

He was also more drowsy, sleeping later into the mornings, and Tomura quickly noticed. In fact, the alpha even seemed… excited?

It was subtle, but Tomura could already catch the change in his omega’s scent — something was different, something new was blooming.

Izuku, however, stopped eating halfway through the meal, his nauseous stomach not allowing him to continue. Tomura growled in discomfort:

— Eat! Eat! — he insisted, using the word Izuku had taught him, while rising and pushing the meat toward the omega’s face.

Izuku turned his face away and gently but firmly pushed the meat aside.

Tomura froze for two seconds, staring at him with wide, confused eyes, trying to understand what it meant. Instinct screamed that something was about to change.
The next day, when Tomura left, Izuku actually fell asleep waiting for his return — something he had never done before, even while lying down.

Now, the smell of flowers bothered him — which was strange, since he had always liked them. The taste of meat also no longer seemed as pleasant as before.
At that moment, they were outside the den, bathing together. Now that they were officially partners, the blindfold was no longer necessary, though Izuku still felt a small sting of embarrassment.

Water ran down his body as he tried to remain steady, despite the constant dizziness. Sometimes his vision darkened for a few seconds, and that scared him, but he tried to ignore the fear and stay on his feet.
He washed Tomura’s white hair gently, trying to pretend everything was normal, while the alpha, cheeks puffed out, was visibly sulking at having his hair washed — he hated the dampness on his scalp.

After the bath, they were heading back home. On the way, Izuku could no longer resist the dizziness and the vision that kept darkening. His body gave out, and he collapsed to the ground, as if his strength had suddenly abandoned him.

Tomura saw his omega fall right before his eyes and rushed to him in pure desperation. Whenever he walked in front, he always looked back, though he preferred to walk behind to watch over him. He sniffed him urgently, making sure he was still breathing, and without a second thought, lifted him into his arms. With wide, frantic steps, he carried Izuku home, heart racing, instincts screaming inside him.

When they arrived, he laid him carefully in the nest. With trembling hands, he removed the artificial skin covering the omega’s belly and, in reverent silence, caressed the spot tenderly. A wet shimmer formed in his red eyes — Tomura knew exactly what was coming, from the scent and instinct, even if the alpha didn’t know the symptoms.

It was true that the omega was suffering with the changes. Tomura had to give his best to ease it.

It was exactly what Tomura had hoped for. His family was about to grow, and that brought a pressure he couldn’t ignore. He knew he had to feed Izuku with more care, more rigor. The responsibility of being the provider, of ensuring everything was perfect for his omega and their future pup, weighed on his shoulders.
At the same time, there was a profound happiness within him. He had always wanted a family, but fear still lingered. The fear of the unknown, of what would happen when the pup was born. What would he do? How would he care for them? How could he ensure everything would go well? He wanted to give Izuku all the comfort possible, but the fears about the arrival of the new life couldn’t be ignored.

..............

When he awoke, Tomura’s face was pressed against his, sniffing him intently, red eyes fixed and worried, as if checking his temperature, his scent, any sign that something was wrong.

Izuku couldn’t say for sure if he was okay. He felt confused, his body strange, as if something inside him was different. Could he have fallen ill, after so long healthy on that island? Right now? Or… was it the possibility he tried with all his strength to ignore? Pups.

The idea itself wasn’t unbearable. In fact, there was something sweet and warm about it. But fear was what dominated. What if he wasn’t a good omega? What if his offspring needed more than he could give? Doubt gnawed at him silently, even with Tomura’s affection so close.

His hand reached Tomura’s head, fingers running through the white strands, in a soft gesture meant to soothe him. He already felt better, though still a little weak after fainting.

— I’m better now… — he murmured, with a tired smile.

Tomura let out a faint purr, almost imperceptible, relieved to see him awake. But as soon as Izuku tried to sit up, the alpha, firm yet gentle, pushed him back into the nest, claws retracted and his gaze more protective than ever.
It was a simple gesture.
Izuku understood, and with a warmed heart, yielded. After all, he was loved.

Tomura quickly went into action. He grabbed a generous portion from the latest hunt and, with swift, determined gestures, gathered dry wood. He lit the fire as before — with skill gained in silence, through repetition and necessity.
The crackle of flames filled the shelter with a sense of coziness. Once the meat was ready, golden and succulent, he approached the nest.
Without saying a word, but with eyes attentive and full of care, Tomura extended his hand to Izuku’s mouth, offering the food gently.
He had to try harder for Izuku now.

..............

As weeks went by, the symptoms worsened. Now, Izuku had a food selectivity that made the alpha’s work harder. He could only eat venison and fish, which forced Tomura to learn new ways of hunting — he was taught by Izuku how to catch fish,
with a branch sharpened by Izuku’s knife.
Bananas, once nauseating, were now tolerable, while blueberries had become completely intolerable — ironic, since in the beginning bananas made him sick. Other fruits had been found along the way, but none seemed to please Izuku at that moment.

Until it became official for the couple — the belly began to show. Now, three months into the pregnancy, the change in Izuku’s body was visible, subtle, but undeniable. Tomura watched it with a mix of fascination, reverence, and pressure, as if that small curve were a miracle he still struggled to believe he was witnessing.
Izuku was still afraid, but slowly accepted the life within him.

For both, it was real now. And each day, the certainty that their family was growing filled the air of the den.

At six months, Tomura was more protective than ever.
He wouldn’t let Izuku leave the den for anything.
Even when the omega insisted on bathing, Tomura resisted, and as a solution, brought those aromatic leaves to help with hygiene.

Izuku, with hormones running high, cried rivers — he was already naturally tearful, but now he was surpassing himself.
The poor alpha, not knowing what else to do, ended up yielding, allowing him to leave, but under maximum watch.

— I look like a pig being fattened — said Izuku, looking at his own body with a tired sigh.

At that moment, Tomura had just returned from patrol, which was now even more intense. The alpha was working harder than ever — between providing food, courting, ensuring territory security, and attending to the omega’s demands — he was always giving his best.
As soon as he arrived, he lay down on Izuku’s round belly, as he did every time, and almost instantly fell asleep, exhausted.
Izuku looked at him with tenderness. He remembered the first kick, and even knowing that his pup was now sleeping peacefully, he couldn’t help but get lost in that memory.

It was a common day, like so many others. Izuku was still trying to grasp the idea of expecting a child. His reason insisted on partially rejecting it, as if it were too big to be real. But, in practice, he couldn’t help the growing attachment.
He was in the nest at night, the alpha resting by his side, the big hand tenderly placed on the belly that was just starting to show. They were curled into each other, and Tomura’s purr could be heard along with his own.

That’s when he felt it. A small kick — weak, but alive.

Izuku suddenly sat up, startled, but quickly regretted the brusque movement. He didn’t want to scare the fetus. Tomura felt it too and lifted his head. The omega’s green eyes filled with tears, emotional. He caressed his own belly with tenderness, while Tomura leaned in, sniffing and purring louder, curious and protective, as if investigating that tiny sign of life.
“Our pup is strong,” thought the alpha, heart swelling with silent pride.

Back to the present, Izuku stroked the white hair, savoring the moment.

...........

His omega had the sweetest scent in the world. It wasn’t like the heat scent — it was another kind of fragrance, softer, laced with vulnerability. Something that made Tomura’s instincts scream to reinforce his presence, protect the territory, ward off any risk, no matter how small.

He didn’t know what their pups would look like, but in his heart, he was certain: they would be beautiful. They had to be. He wasn’t sure how Izuku pictured them — he had even drawn on the wall — but it was hard to imagine without defined colors, using charcoal, blood, or black earth for outlines. The most he could do was mark red eyes with blood.

Before, the omega curled up out of shyness or hesitation. Now, he did it more often, by reflex, by comfort. Tomura found it adorable. Every small movement, every embarrassed gesture or muffled laugh became precious. He watched it all, silent and attentive, like a devoted guardian.

Tomura was at the river now, cold water running down his legs. He needed to get wet, he needed to work harder. Izuku was picky with food, and he had to meet that — whether meat, fish, or rare fruits. He didn’t know why there was all that selectivity, but he didn’t care, as long as he saw him well.

During his old observations from a distance, he never managed to understand the symptoms of an omega’s pregnancy. It was a mystery, an unknown territory. At that time, alphas like him had little tolerance for anything during their omega’s heat or gestation. When he was younger, he avoided looking too much. As he grew older, he observed more, with less fear, though if they noticed an alpha looking, they would attack — they couldn’t stand even other alphas’ eyes on them. The desire to fight overpowered any rationality.

He never thought he’d have a family. Never imagined an omega would accept him, that he’d protect a home. All of that had seemed unreachable, unnecessary… until Izuku appeared. Izuku was his light.

Fishing was much harder than running and biting a throat.

He thought that, even without having the exact words for each action, each sensation. He didn’t need them. He used his spear — the one Izuku had made for him — and admitted it was useful, very useful. But fish… ah, fish were sly creatures, fast. Sometimes they even seemed smart, though he knew they weren’t. They just reacted.
With each attempt, they escaped the sharp tip, swimming in zigzags as if mocking him. He growled low, eyes fixed, jaw tense. When he finally managed to hit one, he pulled it hard and threw the slippery body onto dry land — but, in a second of carelessness, the fish thrashed and slipped back into the water.

Tomura stood still. Fist tight around the spear. Red eyes fixed on the rippling surface. Frustrated. Irritated.
But mostly, tired — he had to hurry, he hated wasting time. He just wanted to bring something Izuku could eat… he just wanted to see him well-fed and happy.

At the end of the hunt, he managed a meager haul: only four fish. Still, Izuku offered one of them to him too, on the first successful fishing. Tomura accepted, curious… and even liked it. How did the omega know so much?

Maybe it was because of those objects with strange symbols, full of images of plants, animals, and markings he still couldn’t understand. Things Izuku guarded with care.

He would leave most of the food for the omega — that was certain. He would eat what was left. Sometimes Izuku had a big appetite, other times he wanted nothing. Tomura had to balance safety with nutrition — it was his responsibility. He returned to the nest with the fish in his hands, feeling the weight of the mission to feed his family.

In that wild world… being an alpha was much harder.

Chapter Text

He was terrified. Whenever an insect approached the den, Tomura would drive them away—guiding Izuku through the forest to avoid encountering any of those disgusting little creatures, and also to prevent him from tripping in the darkness. But now… now there was an intruder. Inside the den.
A spider.

Before, he might have taken the time to observe it with curiosity, trying to study its movements. But now, with his hormones high, all he could wish was for it to leave immediately. Tomura always ensured the insects stayed away—either by removing them one by one or by using the acidity of his urine in strategic spots to repel ants and other bugs.

“Ahhhhhhh!” — the scream came sharp and accompanied by a desperate cry, making the poor alpha run to him with his heart in his throat.
Izuku pointed in terror at the spider, stamping his feet in total panic. Tomura quickly assessed the scene, but his greatest concern was something else: the shock could affect the baby.
Without wasting time, he positioned himself between the omega and the eight-legged intruder, ready to protect, eliminate the threat, and calm his partner.

Tomura acted swiftly. With firmness, he grabbed the spider by the back—a large forest spider, brazen enough to invade his territory. He didn’t know how it had gotten in, but it didn’t matter. He threw the intruder far into the brush with all the force he judged safe. The threat was neutralized.

Trembling, Izuku looked down at his feet and let out a deep sigh. He silently thanked that his shoes were still intact, because if they had been within reach… his feet would have been completely defenseless.
Now, more relieved, he returned to sit in the nest. His breathing was still a bit unstable, and his eyes were moist, but the worst had passed. At six months of gestation, every emotion seemed greater than the last—and Tomura knew that.
The alpha, after making sure there were no more spiders nearby, approached, snuggling beside the omega and touching his belly gently.

Nights were by far the worst hours of the day. Izuku couldn’t settle in one position, which made everything harder for Tomura—the omega squirmed constantly. His feet were swollen, his spine ached continuously, and he missed being able to lie on his stomach. Tomura tried to help, adjusting himself behind him in the nest.

The next morning, poor Izuku yawned for the fourth time in just half an hour, even after a long night’s sleep—and another nap while Tomura was away. The alpha watched silently as the omega rearranged the nest for the third time, carefully adjusting the furs, as if seeking the perfect position.

The poor omega was tearful because he could no longer hug the alpha from the front, leaving poor Tomura very confused.

Later, noticing a piece of fur out of place, Izuku became fussy and began to cry silently. It wasn’t just physical discomfort—something stranger was manifesting. Until recently, he had hated the smell of roasted meat, but now, inexplicably, he began to love it. However, this attraction was contradictory: the intense aroma caused strong nausea, creating a confusing and unsettling sensation.

That day, Izuku sought a way to reduce the swelling in his feet and, as always, used the most efficient form of communication he knew. He drew on the ground using soil to explain what he needed. The problem was finding a suitable container—he just needed to boil some water and immerse his feet in it.
Then he had an idea: the alpha would have to go to the beach or some nearby location to get what they needed.

.............

Frustrated, Tomura finally understood what his omega wanted from him: to go to the beach… again. And all because of a drawing in the shape of a circle?
He sighed, irritated, but then something occurred to him. High in the trees near the coast were small green or brown circles, covered in a texture resembling tiny hairs. Perhaps Izuku was referring to that.
If that was the case, he would have to fulfill the omega’s wish. So, the next morning, he prepared to depart. Upon reaching the beach, he had to climb one of the tall coconut trees, balancing with effort to reach the circle—a coconut, of course.

Once there, Tomura handed the coconut to Izuku. The omega split it in half with the knife—and, to his surprise, there was water inside. How curious!

Carefully, he removed the white part of the fruit, ate a piece, and drank the liquid, and curiously, he didn’t make a face as usual.
Then he prepared the fire, placed the water in the container—which he had retrieved with the alpha’s help, since the omega had a slow pace—and waited for it to boil. When it reached the right temperature, he used the liquid to soften the skin, making it more comfortable.
He placed one foot at a time into the warm water and sighed, relieved.
Meanwhile, Tomura felt good about himself.

Sometimes, even the wind would scare Izuku.

..............

At eight months, the omega looked like a perfectly round ball. Standing required effort and balance, and what bothered him most was the constant need… to use the bathroom. During the entire pregnancy, this had been frequent, but now it was nearly unbearable. Every ten minutes, there he went again—and Tomura, whenever nearby, made a point to accompany him.
When the alpha wasn’t around, Izuku avoided going too far. He did everything as quickly as possible, but it was still uncomfortable.

He was also very clingy; he had even tried to prevent Tomura from leaving—it was adorable, that little spoiled face.
Every time the alpha woke up, the man would try calmly to slip out of the nest without waking the spoiled beast, but Izuku always noticed and grabbed his wrist, and then the poor alpha had to insist, enduring the psychological torment of those teary eyes.
The baby agreed by moving gently.
The poor alpha had to growl, without aggression, to make the omega return to bed.

As if that weren’t enough, he reorganized the nest a million times, never seeming satisfied. He folded cloths, moved furs around. Nothing seemed “right” enough.
The anxiety over the baby’s arrival was overwhelming—and it wasn’t just his. Tomura was anxious too, of that Izuku was certain.

Izuku carried some insecurities that were hard to ignore. He thought about the birth—would he manage it well? And what if something went wrong?
And if… the baby didn’t arrive? And if… he didn’t know what to do? And if… it didn’t survive, or worse, their offspring? And IF EVERYTHING COLLAPSED?
They had no midwives; it was just him and Tomura—if something went wrong, there would be no turning back.
In the next instant, it was like a trigger. Izuku sank into a brief but intense existential crisis. His chest tightened, his breathing became shallow, and his head spun through a thousand different, all grim scenarios.

For Tomura, the situation wasn’t much better. He tried to appear calm, but inside, everything was confusion. He knew nothing about childbirth—as he had already admitted. He hadn’t had the chance to observe or learn enough, and even when he could, he sometimes lacked focus… or interest. Now, he silently blamed himself.

The alpha watched the round omega’s trembling back in silence. He approached cautiously and touched his shoulder gently. The green eyes turned toward him—slightly watery, hesitant.

“What if I fail?” — Izuku asked, voice low, broken.

Tomura didn’t fully understand the words, but he didn’t need to. The scent the omega emitted spoke for itself: a dense, suffocating anguish, like smoke that doesn’t dissipate.
The small one trembled, not only from fear but from doubt. And Tomura, though also uncertain, moved closer and placed his hand over his partner’s tense belly. There lay the life they had created. And also the reason to keep trying.
Tomura’s instincts were on edge too—the paternal instinct, very protective of his omega. His patrols were more intense, and he focused on food rather than gifts. That wasn’t what a pregnant omega needed now; they also went out to bathe, and he took pleasure in washing the belly, back, and hair, including all hard-to-reach spots. With Izuku’s limited mobility, he always helped him stand, though he could still manage alone, of course with much effort.

The big day approached. At nine months, Izuku was cuter than ever—slightly flushed cheeks, full round belly, and eyes even brighter when looking at Tomura. But not everything was calm.
He had been experiencing practice contractions for a few days. However, he decided not to tell the alpha. He disguised the pain with a serene smile, muffling his sighs and controlling every movement carefully so as not to arouse suspicion. He wanted to spare him the worry… for now.
In the nest, he was nestled against Tomura’s body, who enveloped him with long, protective arms. The alpha had just reorganized everything once more—furs, fabrics, soft leaves, the hunt, the fishing, he had paused courtship, Izuku understood—and now rested with his face buried in the omega’s hair, breathing slowly.

Izuku closed his eyes, feeling safe there, even with the growing tension inside him.

It’s almost time, he thought, discreetly pressing his hand over his belly. Just a little longer… and we’ll meet him.

..........

The early hours fell silent, heavy as the breath that lingered in the nest.

Tomura woke upon feeling his omega stirring beside him. Something was wrong. Inside the nest, everything seemed out of place. Not even the furs—those that Izuku had reorganized hundreds of times—were as they should be.
And there was that pain… different.

Izuku was restless. His eyes squeezed shut, his fingers gripping the fabric beneath him. A sheen of sweat already covered his forehead, and his breathing was irregular. It was as if his entire body was signaling: it’s ready.
Tomura approached carefully, his heart racing.
The dense, bittersweet scent emanating from the omega’s body confirmed what he already knew.

“It’s time.” — said Izuku, looking at him, the most feared and anticipated moment.

Chapter Text

Izuku writhed in the nest, waves of abdominal pain growing ever more intense. Beside him, Tomura was sweating more than the omega himself—not from heat, but pure nervousness.

With his knees close together and his body supported on his elbows, Izuku assumed the position instinctively. He had once read that being on all fours helped open the hips, unlike lying down with legs apart, which made it harder for the baby’s head to pass through. It was the kind of information he had never imagined needing… until now.
The contractions came in waves.

Low moans mingled with the silence of the early morning. Tomura, not knowing exactly what to do, tried to be helpful despite being overtaken by anxiety. He had woken to find the smaller one moving beside him, restless, and had been on high alert ever since.
The nest, carefully built with blankets and furs, now seemed too small to contain so much discomfort. Izuku shifted positions frequently, trying to find relief. Even though his water hadn’t broken, his body already seemed to be preparing for something inevitable—the start of an intense, unique, and definitive journey.

Meanwhile, Tomura was deeply worried. He checked on Izuku every two minutes—sometimes observing his tense face, sometimes checking the softness of the nest, trying to ensure everything was comfortable enough. The omega, already prepared, had removed his pants to allow free passage and prevent his clothes from getting wet when his water broke.

The waiting was unsettling, a silence heavy with anticipation. Then, unexpectedly, there was a dry sound of something breaking, like a bag bursting.

By luck, Izuku was already out of the nest at that moment. The water spilled across the floor suddenly, sparing the resting area from getting wet. Tomura, surprised, let out a light alarmed sound and immediately leaned in to sniff the substance, as if trying to understand this new sign with his instincts.

It was the omen: the moment was approaching, and Izuku’s body was beginning to dilate slowly. The omega, bothered by the curious alpha’s nose approaching the puddle, gently pushed his head away—he was checking!

Tomura didn’t like it—he was only trying to understand, trying to help. He had no idea what that water meant, nor what he should do now.
“Ahhhhhh!” — The scream tore through the early morning.

Never before had Izuku felt pain as intense as that of a natural birth. The omega screamed, even trying to hold back his voice, knowing how much it made Tomura even more anxious.

The alpha was completely in the dark. Did labor take this long? Was this normal?

Tomura had no information, no preparation. His omega’s screams disarmed him completely. He felt like he was trapped in a nightmare, useless, surrounded by something he couldn’t understand. He was like a blind man in the middle of a shootout—a poor soul lost in the chaos of the situation.

Until everything was fully dilated, a head appeared. The omega felt relief for a moment as blood ran down his legs. The alpha was so startled by the sight that he hugged his omega too tightly. But Izuku pushed him away, returning to the position on elbows and knees together. Even attempts at comfort seemed frustrating.

Seeing the baby’s head, Tomura instinctively positioned himself to prevent it from falling. He was ready to catch it the moment it slipped. Until finally…

The baby slipped through the birth canal.

“NHEHH… NHEEH… NHEEH…” — it whined loudly.

The alpha took the little body in his hands, ready to lick and clean it, but chose instead to hand it immediately to Izuku, still dirty with blood and fluids.
Izuku, now relieved, received the baby with trembling arms. Still connected by the umbilical cord, they knew it needed to be cut quickly. Izuku reached for the knife and carefully cut it.

Kaoru—the name chosen, in case it was a boy—snuggled against the omega’s chest, whining, already feeling the warmth of the nipple.

Tomura approached cautiously, eyes attentive, body tense, as if fearing to ruin that sacred moment. Meanwhile, tears streamed down the green-eyed omega’s freckled cheeks, still emotional, holding the baby against his chest.

The alpha sniffed Kaoru’s little head, curious about the new scent now part of his pack. He tried to lick the baby—a natural instinct—but was gently stopped by Izuku. Tomura made a slightly childish, annoyed face but didn’t insist. The charm of new life prevailed. He purred so strongly it felt like a small earthquake within the nest.

Kaoru, hungry, quickly sought nourishment. The first feeding was colostrum—the precious “liquid gold,” thick and nutritious, full of antibodies to provide the baby’s first immunity. Izuku offered the nipple, and Kaoru latched without hesitation.

They waited until sunrise to wash the little body dirty with blood and birth remnants. They carefully used a cloth as an improvised diaper. Then Kaoru passed his first stool—the thick, dark meconium. The first and last “clean” poop of a human being, as the old tales say.

................

Adjusting to the new reality was slow, and nearly 80% of Izuku’s attention went to the baby. Tomura faced the greater pressure from routine—he had to patrol more carefully, more intensely. Now it was easy for other alphas to kill Kaoru and take Izuku to have their own offspring with the stolen omega.

The alpha learned his baby’s name, but had a peculiar way of pronouncing it: he called him “Ka’ru.”

Izuku had to balance feeding himself and Kaoru, who was a tremendous glutton. Sometimes there wasn’t even time for a bath, so he used half a cut coconut to store water—whether from the river, when they went there, or from rain. He warmed the baby in his arms and on the furs of the nest. He had to wash the cloth used as a diaper, so he collected more cloths or pieces of fur for use.
He also had to eat and drink, while Kaoru was hydrated by milk. The stored water was rationed carefully for multiple uses, since the alpha was constantly on alert and felt uneasy leaving the den, but it was necessary—Kaoru needed frequent baths, and the water in the coconut wasn’t enough, fortunately the river was nearby and within Tomura’s territory.

Now Tomura was a father. He carried growing anxiety in his chest—his priority was safety and food for two, and indirectly, three. He returned from patrol and hunting panting, sighing in relief at seeing the two safe, nestled in the nest.

He reinforced the territory with his scent, patrolling the surroundings, alert to any strange smell or suspicious sound. It was a large area to cover. He hunted large prey, enough to provide roasted meat and sustain his small family for longer.

After the birth, he and Izuku had to clean the water from the broken waters and the blood on the floor. It was an arduous task—they used large leaves to absorb it, and cloths that would later need washing. It was important to remove any traces to avoid attracting insects or predators.

Yet, Tomura was happy. Complete. His baby was cute—white-haired, freckles across the cheeks, and dull green eyes. Not albino, and Tomura silently thanked that.

At that moment, they were cozy. Tomura leaned against the stone wall, Izuku lay in front of him, and the baby, sleepy, made little noises while clutching the omega’s clothing with his tiny hands. He had a lot of hair for a newborn. The parents covered him with a soft fur, used as an improvised blanket.

Tomura caressed both with his large, strong hands—his two loves. He was exhausted. The sky was already dark outside. It was a moment of silent tenderness, where time seemed to dissolve in the warmth of the nest. His long hair cascading over them, the baby sometimes mischievously grabbed the white hair of his dad, tugging playfully, yet despite the pain, he didn’t get angry.

Only later did Izuku allow Tomura to perform his peculiar cleaning of the baby—but only in certain places. The face was off-limits; bacteria could be in the alpha’s mouth, and Izuku didn’t want to risk his baby getting sick.

He was always attentive: if Kaoru was cold, hot, hungry, or had a soiled diaper. In the book on animals, there was a specific chapter about reproduction, gestation, and care of human offspring. Additionally, there was knowledge acquired from his mother Inko’s former job.

He didn’t want that moment to end.

Kaoru was calm now, which was a relief. Izuku had always feared that the baby’s cries would attract enemies, but Tomura’s strong scent around acted almost like a natural repellent. Still, the omega took care not to expose the baby directly to the cave, protecting him in every detail.
Tomura purred, rubbing his head against Izuku’s nape, his cold nose making the omega shiver; the smaller one purred back, very softly.
Then they slept together, spooning, with the baby calm after feeding, and Tomura watched his little ones sleep, his face serious, having learned to be more expressive with Izuku, but not too much, his heart warm.

................

Tomura was on full alert. An unknown scent, coming directly from his home.
He was mid-patrol; it was pure disrespect.

His heart raced. His claws dug into the ground as he ran in desperation. His whole body vibrated with a fierce impulse, eyes wide in pure instinct.
Could it be that someone… an invading alpha… had crossed the boundary?
“AAAAAAAGGGRR” — a furious roar, the albino alpha’s thunderous warning.

..............

A young alpha, blond-haired. This one wasn’t completely naked—he had red markings on his body, and wore fur to cover his intimate parts. He noticed the scent from afar, coming from the pitch-dark forest. He ventured out of pure curiosity.

He was an exile, wandering. That territory belonged to an alpha—quite a powerful one, at that. The scent of the marking urine was so strong it almost made the blond vomit.
But he needed to see the source of the smell.
Maybe he could strike it lucky.

By origin, he was from the Bakugou group—a small, yet not weak, group.

He sniffed the source of the enticing scent, crossed rivers, passed through dense undergrowth. It was hard to see in the pitch-black darkness, but his instincts guided his steps. He knew the alpha who owned that territory was likely on his trail; his scent was everywhere. He had to be fast.

He reached the base of a quarry where a cave opened in the rock. The scent came from there.
His reddish eyes gleamed with malice.
He almost purred with satisfaction.
A fertile omega… But there was a baby. Small, defenseless. He would have to kill the baby.
Take the omega.

He peered through the cracks at the entrance; the omega and his baby were together in the nest, the baby snuggled against the omega’s chest. He hadn’t been noticed yet—but that was about to change.

...............

Tomura approached the den in desperation, having heard screams. It couldn’t be!
Not now!
Now that everything was perfect… he would die of sorrow if his omega and child were taken.

He arrived with a racing heart and heavy breath, ready to fight.

What he saw upon entering the den made Tomura growl—he was now a desperate alpha.
The blond alpha tried to grab Izuku’s baby while the omega protected the little one with his body, keeping his back to the intruder the entire time, crying and screaming, while his child also cried.

“N-NO!” — he cried.
Everything happened within seconds.

The intruder noticed Tomura’s presence, turned with red eyes—almost like his own—casting a defiant look. He was a younger alpha than the albino.

An alpha protecting what was his—against an alpha thirsty to steal.
The next step was the attack. Tomura now had two very important lives at stake

The blond alpha was ripped from the nest by a claw attack, while Tomura aimed straight for his chest and throat. The two bodies collided—the blond had larger claws, but was weaker. Still, he had firm muscles.

Tomura managed to tear open the intruder’s chest after a moment of distraction.
The blond was killed, and his body dragged to an open area, where his carcass would serve as food for others. But before that, Tomura took his share—according to tradition.

Izuku was in shock, but the baby was safe now.
Then the albino alpha checked on his omega: Izuku had a few scratches and bleeding on his back, but now everything was secure. Of course, Izuku began his usual self-care routine, with Tomura’s support.

Chapter Text

Amid the noises of the night, Kaoru was curled up in the furs inside the nest. They had wrapped the little one in extra fur, between the warm bodies of Izuku and Tomura. The mission was clear: protect the baby from the night’s cold.
In the silence, broken only by the soft sound of the baby’s breathing, the alpha stared into the darkness, lost in his own thoughts.

Tomura wondered if he was being a good father. Was he doomed to repeat his progenitor’s mistakes?
The image of that aggressive, arrogant, hateful man appeared in his mind like a persistent shadow. He feared becoming the same.

He was afraid of losing control someday. Even being patient with Ka’ru’s cries and difficult moments… what if… what if one day he wasn’t?
What if, like his father, he looked at his own child’s face and felt anger — and not love?

He pushed those thoughts away with a heavy sigh, pulling Izuku and the baby a little closer. His instinct was to protect — not to harm.

Tomura, now the only Shigaraki, before Ka’ru, after the baby was born, the little one was the second Shigaraki on Valmora Island. Of course, the alpha had no knowledge of the island he inhabited, nor of the outside world, unlike Izuku, who came from an unknown world.
Of course, despite there being two Shimuras on the island, the tribe was still extinct. Having only two individuals of a certain group, or species as an example, did not mean the species was no longer considered extinct.

Touching his two loves and reflecting deeply, to the point that the night birds stopped singing, he had an existential crisis. But it was a positive crisis!
He could watch, protect, and stay close to both of them for years, never tiring.
He would do anything for their safety.
How could something so small be his?
The baby’s body fit entirely in his two palms, not fully stretched.

Now it had sunk in — he had a child with the omega he loved, who had waited to be accepted after so much effort, a family of his own, only his. He purred while looking at Ka’ru and his Izuku.

………..

Izuku had another dilemma, completely different, concerning the present and the past.
First, he was doing his best for Kaoru, but he had that fear — the fear of doing something wrong to such a small, fragile being.
He remembered the licks Tomura gave Kaoru, and that he also held him later. In the end, the alpha had his instincts to guide him, because of his connection with that wild world.
But even the alpha seemed bewildered about what to do, at that moment. The omega had to help poor Tomura figure out how to hold the baby.
Afterward, the alpha stared at the baby for hours, just observing and touching his little face — how he had traits of both, and eyes that held a universe in green.

And if, in the future, he did something with the child that could harm the baby’s well-being and health? He feared being ignorant and not knowing what to do. Some things were not in books — only in experience.
If his mother had been there with him, it would have been a great help.

And secondly, there was the past. What had been.
Had his mother received his letter? Did she miss him? Was she okay? Had she dealt well with his departure?

The worry weighed on his chest.
The woman had probably fallen into depression and died of sadness… or carried on with her life.
Izuku often felt like a burden to her — an extra mouth to feed, with the little money that barely covered two people. Perhaps, in the end, his departure had been a great relief.
Guilt consumed him during his days on the island, in trying to gather money for a crazy expedition.
Part of him thought otherwise — in that remote place, he had found an alpha who cared. And now he had a fruit of love with him, and there he could be himself, without external pressure.

But Inko was an attached mother, even if she had failed sometimes.
But don’t worry!
The guilt was not yours!
To err is human… — he thought, trying to console himself.

………..

It was not easy.
The last years had been the worst of her life.
Worse than when she lost her husband and had to raise a child alone, nothing compared to loneliness, the absence of a loved one.

Without her Izuku.
Her baby.

(As every loving mother knows: it doesn’t matter the age — children are always your babies. Always. Compared to newborns… as on the day the baby is born, so is a mother.)

It all started on an ordinary day.
She woke up, would get up to make breakfast for herself and her son, as was the routine.
She was going to work.
Izuku was going to… study.
He also worked with her, although to a lesser extent.

“Studying…
Crazy, isn’t it?”

— Izuku! Come have breakfast with mommy! — she shouted.

Until her baby didn’t come when called.
It wasn’t his usual delay, it was a long delay…
Until Inko went to his room and found… nothing.

She only remembered, after that, searching for him everywhere. She missed a day at work, looked in the neighborhood, even beyond it.
That night, exhausted, she returned home and cried.
Where was her baby?

Nothing I write here can describe her despair.
The answer came the next day.
She spent the night awake.
During the day, she received a letter while at home.
She didn’t eat, spent the day crying and trying to look for clues.

At the end of the day, she decided to read it.
Unbelievable.
“Where did I fail?”

Apparently, her baby had fled to a remote island.
From that point on, living without him became a true hell. Gradually, an absurd idea began to form in her mind — a desperate idea, born from the pain of a poor mother.
Of course, this did not arise immediately. It took years for Inko to consider this feared possibility.

Those years were arduous. She stopped talking to the neighbors, her appetite fluctuated — eating too much some days, almost nothing on others.
She had to justify her constant absence at the house of the woman she worked for, among other responsibilities. She missed many days due to the depression she developed; sometimes she planned to end her own life, life seemed meaningless, she didn’t know why to continue, instinct prevented her, she wasn’t dismissed… for being very good at what she did.

She felt guilty for not listening to her son’s thoughts. Maybe he was already dead…
But she had to admit: he was so intelligent, so good. She had been so lucky to have a son like him — even with his contradictions to social traditions.

Perhaps, if she had truly listened to him… he would not have escaped her arms.

Back on Valmora Island — a name known among the tribes, except for Shigaraki, the alpha, who had never heard of it. The origin of the name was unknown, though there were rumors that someone mispronounced it while trying to say another word.

Just like the Dark Forest, where Tomura lived, there were many legends about it. The Shigaraki tribe had only one version — and even that was not fixed; everyone interpreted it differently.

At sea, a boat approached, almost identical to the one that had brought Izuku.

“I’m coming, Izuku…,” she thought.

Chapter Text

It all began like a normal day. Kaoru was fussy in his arms, and Shigaraki was protective as always. Until the sun reached noon — measured by the shadows of the trees, through the cracks between the dense leaves. Sometimes it was hard to tell if it was day or night, but it was possible to look through a wider gap in the canopy, where the light drew dots on the ground.

But Tomura was restless today, as if his instincts told him something was coming. Not necessarily bad. But not exactly good either.

Izuku rolled in the nest. The alpha sniffed the air, stood up by the entrance, and frowned every moment.
Izuku watched once again as Tomura rose and peeked outside — he was starting to get tired of it. Even Kaoru whimpered uneasily against his chest, feeling his alpha father’s pheromones.

“Tomura?” — the green-haired omega called, but the albino didn’t pay attention.

Izuku stood up, still somewhat weak. The first postpartum weeks had been harsh, and he still carried the baby in his arms. He went to Tomura’s side.

The omega peeked outside — everything seemed normal, until he looked up.

Smoke?

..........

Tomura followed Izuku, who had darted into the forest, even stumbling sometimes on roots he couldn’t see, or on his own feet.
The only thing the albino remembered clearly was the moment when the omega handed him the baby — and ran.
He had never thought an apparently fragile omega could run that much. The omega kept going through the clearings, toward the distant smoke.

And he was heading to the beach.

“Gggrrr?” — Tomura growled, trying to call him.
Of course, he caught up — grabbed his arm — but the omega slipped away and kept running.
This time, Tomura simply followed.
It must be important.
He couldn’t explain why he let him go like that, even though he disagreed.
He now ran with the baby in his arms, who was startled by the movement.
Tomura had noticed the smoke, but it didn’t look like fire — maybe Izuku knew what it was.

By then, Izuku had reached the coast, after a long run — and many pauses, really many — when he saw men and that floating thing on the sea.
Red eyes widened, and he pulled Izuku’s arm back into the bushes. He seemed nervous.

“Grrrr” — he growled low, as a warning.
“No, Tomura! I need to see who they are!”

Even though they spoke quietly, and the baby was surprisingly calm now, Tomura’s albinism was a curse.
Soon, his white form was spotted.

“There’s someone there!” — one of them said.

Sensing the threat, Tomura quickly handed the child to Izuku and faced his greatest fear: sunlight — and his enemies.
He leapt like a feline, claws and fangs bared.

The men were startled, barely had time to prepare a defense. One of them was struck — Tomura went straight for the neck. They had no fighting skills, but carried weapons, like Izuku’s knife, only longer and heavier.
The smoke came from the same kind of magic Izuku used — and the alpha too.

To see their companion attacked by a cannibal right after arriving... the legend about the island was true!

In just two seconds of thought, they acted: they pinned the albino cannibal — a super rare skin in humans — to the ground.

Tomura struggled on the ground, surrounded by giant blades. They were more in number. Still, his body moved on its own to attack them.

It was what any alpha would do in his place: defend, protect.

Also in seconds, Izuku acted — ran out of the bushes.
Tomura screamed when he saw him rushing into danger. He should have run!

“Stop! Don’t do this to him!” — the men looked at the young man. They didn’t even notice the child in his arms.

“Izuku!” —
At that moment, the green-haired boy heard a familiar voice. For a second, he thought it was a dream.
Or better, two voices at once.

“Mom? Mr. Aizawa?” — Izuku saw the two figures running toward him — and then, the embrace.
So much had he dreamed of his mother’s embrace… and now it was happening!
Izuku was already crying. Inko too. The Midoriyas were big crybabies.

Then, he hugged his teacher.
Kaoru whined being squished in the middle, but no one noticed — emotion surrounded them like a warm, intimate bubble.
Only after Izuku calmed down did he turn to his mother and hug her again, tightly, with force.

“How did you get here…?”
“The same way you did, but Professor Aizawa helped me with it” — until now, the man had been silent, not daring to interrupt the moment.
Izuku remembered Tomura, still on the ground, trying to regain advantage, failing, and his skin was turning pink — the longer he stayed there, the worse the burns would be.

“Please, make them let him go…” — his mother’s voice trembled with supplication.
She looked at Izuku, confused.

“But Izuku… he attacked those alphas! Let’s go home!”

Izuku lowered his eyes, wavering between shame and resolve.

“I can’t leave him…” — he murmured, voice low but steady. — “He is my alpha.”

And then he exposed the scarred mark on his neck.
Silence. Like a mute thunder falling among them.

“What have they done to you?!” — Inko exclaimed, in a burst of pain and disbelief.
Seeing that the men didn’t move, she herself tried to advance, but Izuku was faster — crossed the space between them, defying the sharp swords without hesitation.
The alphas tried to stop him, but Izuku didn’t back down. He stopped in front of the albino man, firm as a wall. His chest heaved, but his gaze didn’t waver.

Tomura watched, attentive. His omega murmured words in that strange language, full of sounds he still didn’t understand. But the tone… the tone he knew.
He was defending.

Tomura knew. He knew Izuku came from that people — from those ships and cold stone constructions. It didn’t matter.
To him, Izuku belonged to the nest.
And should return.

Tomura rose, even under the tense and watchful gaze of the men.
No one commented on his nudity — though the discomfort was palpable, it was expected, after all, he was a savage.

Izuku remained firm in front of him, as if he were his shield.

“Problem child… stop this nonsense and let’s go back!” — Aizawa’s deep voice finally sounded, after long silence. It already carried a tone of irritation, tired of his student’s usual stubbornness.

Tomura didn’t understand the words, but he understood something worse.
Fear.
Fear that Izuku would leave.
Fear of losing his omega.
No… it couldn’t happen, not to him.
What would his miserable life be without him?

“I can’t… after all, I have an alpha and a child here.”

Only then did Inko notice the baby in Izuku’s arms.
Before, in the heat of the moment, Kaoru seemed invisible — overshadowed by the reunion, the tears, the relief.

“It can’t be…” — Inko murmured, stunned.

Aizawa, for his part, had his eyes wide open, jaw almost hitting the ground.

Tomura growled, calling him inward. Deep down, he was scared — he wanted Izuku close, safe, away from those unknown figures.

But the omega didn’t listen. He was tense, body upright, staring at the chubby woman, with that same style of artificial furs he knew from before.

“Your grandson’s name is Kaoru. And this” — he said, gently pulling Shigaraki by the arm — “is Tomura, my partner.”

The alpha seemed impatient. He wanted to return quickly to the shadows of the forest.

“HOW CAN YOU DO THIS TO YOUR MOTHER?!” — Inko screamed, in tears.

Izuku ran to console her, hugging her tightly.

“Please, forgive me…” — he said, voice choked. — “My escape wasn’t meant for this… but it happened…”

He took a deep breath, eyes brimming:

“I fell in love. And now… I can’t imagine my life without them.”
The decision had been made.

In the end, Izuku had some time with them, before the ship departed — without him.

Deep down, Inko didn’t want to see her son sad. She knew the Kingdom of Musutafu couldn’t offer the happiness the omega had found there.

She left with a promise: she would always save money and come visit him once a year.
Her days would still be lonely.

Now, relieved, she knew her son was well.
