Boyfriends with a Demon Lord.

Summary:

Izuku, bless his soul, manages to sleep mumble a confession in his sleep and what does Katsuki do? Burst into flames and gay panic.

Very funny, very gay panic. Poor Katsuki. (Catching aflame when flustered seems awful, honestly.)

As Katsuki Bakugou once thought; "FGHFKHF ?!??!?!?"

Thank you for coming to my ted-talk.

Work Text:

In the passing months after Izuku had opened his own warp gate to hell, the divorce was finalized. Hisashi had to give all of his wife's stuff to her, along with ¥1,098,200 (Ten thousand dollars) in assets.

Thankfully, his name was on the lease for the apartment, and he was able to keep the apartment. He was also granted full custody of Izuku, and Inko didn't fight it. She just stood silently to the side, tears in her eyes, but they didn't fall.

A month after the divorce, an anonymous tip along with photo evidence on child neglect and abuse on Inko's part had made its way into JPD's hands, and Inko was quickly arrested. After JPD found the evidence to be true, along with a voice recording of Inko screaming at her child, Izuku.

Hisashi had an inkling that it was Izuku who sent the tip in, but there was no evidence on that suspicion. After the two were free from the divorce, Izuku was far happier, and caught up on so much sleep, his dark eye bags receding with every sleep-filled night, along with Hisashi, who bettered his ways, and became a great father for Izuku.

Katsuki had also found out something shocking. (Is it? Really?)

Let's play the scene back, shall we?

------------------------

Katsuki sat next to Izuku's bed, carding his fingers through soft, inky black feathers, watching them twitch on Izuku's wings as the fifteen-year-old slept, a smile still gracing his face after being accepted into U.A. The teen had warped to hell, a bright smile on his face that rivaled an angel's smile, lighting up hell with a smile worth a thousand innocent souls. Some demons had to shy away from the teen, shielding their eyes to hopefully not burn from the sweet smile Izuku wore.

He gushed and shook Katsuki about being accepted into his dream school, about being able to make his dream of becoming a hero a reality. Katsuki had been a little dizzy till the rest of the Bakusquad had come around to congratulate him, till Izuku had gotten sleepy, and Katsuki accompanied the teen back, and stayed there till he fell asleep. He decided to stay for a while, just basking in Izuku's soothing presence, playing with soft feathers and sweet-smelling curls, Katsuki was content.

Izuku seemed to be as well, letting soft, sleep-muddled chirps and purrs, leaning into Katsuki's warm hands, letting soft puffs of air out of his pink lips, floating away into a warm dreamland. Katsuki smiled softly, eyes glowing with a certain fond emotion filling his chest, ballooning in his chest.

Love.

Katsuki was utterly and hopelessly whipped for his beautiful little nerdy demon, the boy he met nine years ago when he was six. He was now fifteen, already a few weeks into hero course at U.A. Yea, Katsuki was in love with the little nerd who mumbled, cried at the drop of a hat (Seriously, he dropped a hat once and cried.), and had a love for heroes. He loved him, especially when Izuku would seek comfort in him.

Big, nine-foot, demon lord, asshole, him. It made him feel warm inside, knowing that, no, the nerd wasn't scared of him, and sought comfort in him. He loved when they curled their tails together, laying on the couch while re-watching all of the seasons of the All Might cartoons they've re-watched, most likely over a hundred times in those eight years.

Katsuki would never get sick of the cliche "I AM HERE!" and reciting word for word of each episode with Izuku. He loved when Izuku would chirp and purr when they hugged and cuddled, falling asleep in that position quite a few times. Yeah, he was a sap of a Demon Lord. But could you blame him?

Izuku was precious.

While Katsuki was caught up with his inner gay musings, Izuku decided to sleep mumble, causing Katsuki to look at the snoring teen, a smear of drool coating his lips, mumbling nonsense.

It seemed the nerd was having a dream, Katsuki thought, never stopping his hands from carding through Izuku's feathers, plucking old and dead feathers out of the wings, keen ears listening to Izuku sleep mumble about needing milk? The nerd must of be having some weird fucking dream. But then Katsuki heard it; the soft, unintelligent mumbles turned into half-sentences filled with (mostly) nonsense. "...lo...ve you...kacchan.. always....lo...loved you..." Izuku mutters softly, still asleep, scratching his thigh before falling back into his dream.

Katsuki's face goes stark white before erupting into flames. (No, seriously, there was a lick of flames coming off of Katsuki's face. Catching fire when your flustered doesn't seem nice.) Did-

Did he hear that shit right?

Katsuki was either going bat-shit insane (his heart definitely was), or the nerd actually said that. Said that he loved Katsuki. Katsuki is pretty sure he's having a heart attack.

Can demons have heart attacks? He has no idea, but it feels like his heart is going fucking insane.

Does he know what a heart attack feels like? Is this what it feels like? He doesn't know, nor would he like to find out.

Why is his fucking ear on fire? Is this why his mother told him never to fluster another demon?? Because, oh, I don't know, the ERUPT INTO FLAMES??

Okay, holy shit, where is the calm, conceded Demon Lord-

Fuck, is his heart okay? That bitch seems like it's having a fucking asthma attack-

Hngggg- The nerd is gonna kill him, or the flames that will not go out on his face will-

Breathe, motherfucker, breathe.

Okay, Izuku didn't just confess his undying love in his sleep. He's perfectly. fine. Fuck you.

Fuck, he just wants to scream, but fuck, he mustn't wake his tiny lover- (He's not even yours?? Get it together, Katsuki???)

Is this what Kaminari would call a"gay panic"???? Holy shit, is he gay panicking??? Shit, if he is, he'll never tell a soul. (He's totally gay panicking, motherfucker; stop thinking with your dick- GO AWAY HORNY THOUGHTS-)

(FFFFFFFFFFUUUUUU AAAAAAAAAAAA- Is this how you appropriately use that internally screaming meme Izuku showed him?? How the fuck does he even figure out what memes are?? They're so fucking confusing?? But, onto another train of thought, internal screaming. Because he feels like he's screaming and mgfhgfh FUCK-)

If he doesn't calm the fuck down, Izuku will have a few new holes in his floor. He doesn't feel like being scrutinized under Izuku's disappointed stare. It feels like he's back to being four, and his sire is staring him down.

WHY IS HE THINKING OF HIS PARENTS IN THE MIDDLE OF A GAY FUCKING PANIC?? WHERE ARE YOUR PRIORITIES, KATSUKI??

Katsuki steals a look through the gaps in his hand where his head rests at Izuku, who snoozes away, shucking the blanket off a bit from how the temperature in the room spiked (from Katsuki losing his shit over a love confession from someone asleep-) and Katsuki comes face to face with pretty supple thighs, packed with muscle that could probably crack a watermelon (Or his head-) with them, smattered with clumps of freckles everywhere.

Oh, dear Jesus, he's about to fucking die-

Here lies Bakugou Katsuki, Demon Lord of hell.

Death? Pretty freckled thighs.

Fuuuuuuckkkk-

Katsuki promptly closes the gaps in his fingers, staring into his palms, resisting the urge to bash his head into the floor.

He's down bad, huh?

If Dumb and Dumber were here, they'd slap him with a sticker (how the hell they got stickers in Hell is beyond him. He suspects Izuku.) that says "certified simp." And fuck him sideways; he's a down bad, certified simp for the precious little being in the bed in front of him. Katsuki raises his head, resisting the temptation of driving his hand into his chest to rip out his heart (It's not like he needs it anyways) to stop the thundering of the muscle going bat shit insane in his chest.

His tail whips and thrashes in annoyance as he starts to calm down, patting another mini fire out on his pointed ears, resting his chin on Izuku's mattress, the foam compressing under his head. Katsuki stares at the freckled beauty (no, not Izuku's thighs, you heathen.) that rests in front of him, and closes his eyes.

He doesn't remember when he fell asleep, but waking up to Izuku scratching his head while reading something on his phone is awesome.

------------------------

Izuku and Katsuki lay in bed, having gone to Katsuki's realm seeing it was a Saturday, and Izuku's father said he most likely wouldn't be home till early the next morning. They both decided to laze around in Katsuki's giant bed, Izuku curled into his chest, dozing, often replying to texts from his few friends he had made in school, allowing Katsuki to read along, the two often share laughs at the stupidity that radiates in the Hell class (dubbed by a very sleep deprived Aizawa.)

Katsuki watches fondly as Izuku shuts his phone off, letting it lay to his right, laying uselessly on Katsuki's bed till Izuku decides to open it again, their tails intertwined as Izuku rests his eyes. Katsuki quietly counts the new freckles on Izuku's face, looking at a freckle that rests right in the tip of Izuku's cupid bow on his lips, looking awfully kissable.

Oh-

Katsuki wants to kiss Izuku.

He decides, fuck it, if this goes wrong, he'll apologize, and it'll never be the same. (Or maybe he'll throw himself into the pit of ever-suffering in his embarrassment, or that lava pit he conveniently has-)

Katsuki grabs Izuku's face, caressing his soft, pudgy cheeks that never lost their baby fat, dipping down and catching Izuku's lips in a soft, loving kiss. Izuku makes a soft noise, a muffled chirp, and reciprocates the kiss. (Not now, heart, have a fucking heart attack later-) Izuku pushes himself up, so Katsuki doesn't have to bend his neck at an odd angle, laying on Katsuiki's chest, purring into the soft kiss. Katsuki pulls away, a little breathless, pupils dilated as their tails continue to intertwine.

Their both purring loudly, their purrs mingling, making a cozy tune, something perfect for soothing a fussy babe- (Katsuki puts away the thought of a cooing babe with Katsuki red eyes, blond curly hair, and freckles. He shoves the thoughts into a mental list for later Katsuki.) They both have dopey, soft grins on their face, going back to peppering kisses and rubbing cheeks with each other, chuffing and purring.

Izuku giggles and chirps happily, the sweet, natural aroma Izuku emits tinged with glee and content, making Katsuki fill with warmth. Katsuki rumbles something deep in his chest, Izuku making a similar, more high-pitched rumble in his chest.

"Be mine, love?"

A teary smile with glittering green orbs filled with nothing but pure love stare at Katsuki, "Of course!" He gleefully laughs as Katsuki nearly deflates, sighing happily as the large blond cuddles into his chest, large arms enveloping his sinched waist.

"What is 'be mine' implying, Kacchan?"

"Interpret however you like."

"I'm interpreting it as a marriage proposal."

"Pfft- IZUKU WHAT,"

"What? You don't want it to be?"

"Oi- don't put words in my mouth-"

"Love you, Kacchan!"

Katsuki's face erupted into literal flames at the confession, and Izuku laughed at him.

Motherfucker-

(He, once he had patted out the flames for the nth time that week, said those words back to Izuku, who turned cherry red.

Payback, bitch.)

------------------------

When Monday comes, Izuku walked into class with a calm, happy aura around him. He looks especially happier today, eyes filled with a certain emotion they can't exactly pinpoint. It seems something good happened to Izuku in the past few days. Uraraka, who had an evident, awfully hidden infatuation with him, skipped up to him, pushing her arms in and jutting her breasts out to make them better, starting to coo and flirt with Izuku. (Kacchan has bigger, better tits, thank you very much.)

Izuku makes conversation with Tsu, who looks halfway to apathetic, and somewhat a smidge jealous. (Izuku may be a little dense, but he is very observant. He knows his little frog friend obviously has a crush on the zero-gravity girl, but had no ill-feeling towards Izuku, which is great. Tsu is a great person to talk with.) Iida is chopping his hands somewhere, talking to Aoyama, who stares into his (non-existent, cause y'know? Demon?) soul, munching on cheese as Iida chastises the teen about eating in the classroom.

At his desk, Tokoyami stares at the ceiling, wondering why God has forsaken him with such loud classmates. He and Tsu make an easy conversation, before his pointed ear twitch. He looks at the door, shifting to nod his head to Tsu, who sits back down at their desk as Izuku makes a bee-line for his desk, sitting in his chair as the door was thrust open.

Aizawa stands there, anger flaring in his quirked eyes, glowing a toxic red as everyone shuts up and sits down. (He's already expelled six people from the hero course in two weeks, a prevent named Mineta and five other people who were only here for fame, money, and to flaunt that, yeah, they're in the hero course at U.A., loser! Yeah, once they were found out, Aizawa kicked them to the curb, his sadism (And nezu's) fed by their affronted cries of he can't do that! and that's not fair! )

Aizawa shuffles and closes the door behind him, speaking about a trip. Apparently to USJ? (Izuku knows it's the Unforeseen Simulation Joint) but Uraraka and Hagakure think that they're going to Universal Studios Japan. Those poor, air-headed souls.

------------------------

Iida chops his hands as they exit the bus, entering USJ in a single file line. Izuku dons his hero costume, a hybrid of Hawks costume and Aizawa's. Instead of the slightly flimsy boots Hawks has, Izuku had chunky combat boots. Instead of the tan jacket and pants, he wears a tight shirt with no arms and a high neck, showing off his muscles. His pants are black, and he does not protect his eyes, ears, or hands. His wings and tail fit through his clothing just the way he designed it.

His pants also have many different pockets, holding medical supplies, knives, and other things he needs for heroing. His costume is sleek and is quite good for sporadic, taxing movements.

When entering USJ, the hero Thirteen is there to greet them; her upbeat voice boosts their spirits, talking about the dangers of their quirks, and how any quirk can be categorized as dangerous. Any quirk could kill in the right sense. Izuku listens closely, tail swishing and wagging, seeing Thirteen was one of his favorite heroes, along with Uraraka's, who looked about ready to squeal and float off into nothing.

But suddenly, all the hairs on Izuku's body rise, pupils slitting and feathers puffing. Something is wrong-

"Hey, they even have fake villains for us to fight! Awesome!" Ojiro points to the plaza, and Izuku knows, something very bad is about to happen.

------------------------

Aizawa's face is bashed in, once again, into the concrete, sick squelches coming from the blood pouring off his wounds on his face. His slick, greasy black hair is doused in his own blood. Izuku is shaking, not in fear, but in anger. His claws slice out of his fingers, elongating as Izuku rises out of the water, making Tsu look at him in worry. He doesn't mind her, body quaking in anger. They've hurt one of his own.

(A voice, low and dangerous that sounds like Kacchan speaks in his head, "Protect what is yours, baby, we're demons, we're naturally territorial.")

Izuku's shoes crack the concrete as he rushes forward, wings outstretched, claws, fangs, and tail oozing the inky venom that smells of potent death.

Shigaraki laughs, taunting, as he watches the demon-quirked child head straight for the Nomu, eyes glowing a ruby red. He scratches at his neck, calling out for the Nomu, "Nomu! Take this little NPC out!" The villain quakes with cackles as the Nomu answers his command, dropping a very limp teacher and rushing towards the boy who doesn't falter in his step. The nomu is quick, faster than the blink of an eye, as the creature's fist thrusts through Izuku's body, coming out the other side with many of Izuku's crushed bones and organs.

Shigaraki expects the boy to scream in pain and write, die, on the Nomu's fist, but the boy stands still, the horrified screams of his classmates echo in the quiet facility. Blood trickles from the boy's lips, and a pointed, forked tongue licks it away as the boy smirks. The teen's hand shoots through the Nomu's chest, holding a beating heart on the other side, claws oozing venom, the venom spiling back into the wound and dripping onto the floor, eroding the concrete away.

"That little trick of yours," The boy speaks, voice low with a smirk clear as the Nomu suddenly writhes in pain, pulling his fist free, making the boy's arm rip out of the monster's chest, the oozing venom coating the wound even more. "That shit doesn't work on me." The boy's tail lashes, wrapping and puncturing, injecting something as he opens his wings, watching the Nomu writhe and scream, tearing its own skin off, trying to get it to stop.

Izuku grabs Aizawa, making distance from the screeching Nomu that bulges, welts forming under its skin, boiling, eroding, and hot, steam hissing as skin is constantly torn off. Izuku's caved chest fixes itself; the only thing amiss is the giant hole in his shirt as Shigaraki screams, "WHAT DID YOU DO TO MY NOMU?!" Flakes of skin is scratched off as the Nomu suddenly halts all movement, eyes rolling into the back of its sockets, popping like an overfilled balloon.

The oozing, searing flesh of the Nomu explodes everywhere, getting on every downed villain, Shigaraki, and Izuku. Izuku uses his wing to keep the flesh from hitting them, his feathers fire and venom proof, shaking the searing flesh off. Everyone stares in shock, horror, and disgust as someone throws up somewhere, gaining a chain reaction of vomit. (He's pretty sure Tsu chucked up her breakfast into the water after getting out.)

Shigaraki heaves a gag, smelling too rancid sweltering flesh that lays on his skin, oozing all different kinds of liquid as he steps (more stumbles) into a portal after he screamed for Kurogiri and him to retreat. Shigaraki has seen some messed-up shit, but his nomu exploding is at the top of the list.

------------------------

Aizawa is taken away in an ambulance that races down the road from USJ, working on stabilizing the teacher. Izuku's classmates stare at the teen who seems quite chill after seeing a Nomu blow up, answering questions for Detective Tsukauchi, who looks a little green at the accurate telling of the Nomu blowing to bits as his colleague's heave and gag into their hands at the sight. Tsukauchi doesn't blame them.

The teen seems calm, and also seems to have an iron stomach as a piece of still steaming oozing flesh piece is picked off his right boot for testing, still eroding.

"How did the uh... Nomu...blow up..?" Tsukauchi asks Izuku, who fiddles with his tail. "Ah... I may have used my most potent venom on it...?" The teen nervously laughs as Tsukauchi's quirk pings truth. Tsukauchi nods, clearing his throat to keep the bile from crawling up his throat. How fucking potent is this kid's venom to blow up a bioengineered monster that could take down All Might? "Midoriya-kun? Would you be willing to give us a sample of said venom?" He asks, making the teen look up. "Sure, I don't mind."

An EMT holds up a vial used for transferring hazardous acid, seeing the teen told them it would most likely erode any glass away. The vial was from Yaoyorozu, one of Izuku's classmates who gladly offered her help with her creation quirk. Izuku grabs the vial, opening his mouth as everyone watches. His giant fangs glow in the afternoon sun as one is sheathed with the vial.

Izuku closes his eyes, focusing on creating one ejecting point for his venom, the oozing, sticky venom shooting into the vial, the black liquid sloshing as half a vial is filled with the boy's venom before he pulls the fang out, capping it and licking his canine to get rid of the venom left to ooze down his canine. The EMT is handed the vial, staring incredulously at the venom that fills the small vial.

The venom is hot, thick, and sticky, sloshing with the movement of the glass vial, warming the EMTs hand as he gets it in a styrofoam holder, setting the vial into a hazard box, ready to be shipped off to a lab with clear instructions to "NOT GET ONTO SKIN OR TOUCH! WILL ERODE AND WILL KILL".

The class is ushered into the bus, sitting still, some still fidgeting with nerves. Tsu sits beside him, looking at the teen who plays with the soft tuft of fur at the end of his tail. "Midoriya-chan, kero," Tsu croaks, making everyone and Izuku look at her. "Yes, Tsu-chan?" Izuku asks, tipping his head, looking like a lost puppy. "You looks happy when you came in today. Is there any particular reason? Kero."

Izuku's face suddenly erupts a soft pink, eyes glowing with the same emotion from earlier.

"Ah...I've had a crush on this guy I've known since I was six, and we had gotten together the other day. He asked me to be his boyfriend," Izuku mutters softly, a small smile on his face as he fiddles with his fingers. Tsu's face brightens as a soft smile comes over her usually apathetic face, "Congratulations, Midoriya-chan, kero." Tsu croaks as Izuku smiles. Others give their congratulations as Uraraka clenches her fists in the back of the bus, stewing with jealously.

She looks up, seeing the soft smile on Tsu's face, a soft rosy color painting her cheeks. Her cheeks suddenly flair, looking away. "Who's your boyfriend?!" Hagakure squeals from a row over, gloved hands flapping in glee.

"Ah, he's a Demon Lord."

....

"...what."

"Mhm, my boyfriend is an actual Demon, The Demon Lord."

Tokoyami suddenly sits up straight, looking straight at Izuku. "You- You mean your boyfriend is Bakugou Katsuki? Demon Lord of hell?!" Tokoyami squawks, looking intrigued as everyone perks up, even Shinso in the back row.

"Yes."

Izuku pulls his phone out, showing a photo Katsuki had taken when he was asleep next to him, his and his boyfriend's body clearly visible, along with his boyfriend's large, devilish face, a soft smile gracing those lips.

Tokoyami stares in shock at the photo before passing out.

The bus erupts into chaos as Izuku sits, smug about the fact that, yes, his boyfriend is THE Bakugou Katsuki, Demon Lord of Hell.

(They do hound Izuku for answers, but he simply smiles, imitates a zipper closing over his lips, and skips off, after they were checked and released to go home early.

His friends tried to follow, but Izuku had disappeared into an alley, opening a portal to hell and falling into his boyfriend's arms, and breaking down. The whole event finally came crashing over him as he filled his boyfriend in on what happened. )
