Chapter Text
─────
Aizawa gritted his teeth, he was supposed to be teaching his first class ever at UA today (read: sleeping in the floor waiting for a bunch of teenagers to shut up), not fighting a random villain that decided to ruin his plans for the day.
"STAY STILL, LITTLE HERO!"
He wasn't little (he actually grew up several centimeters, no matter what Hizashi said), but to the gigantic man trying to slap him into the next universe, he might as well be.
Yes. Yes, this violent psychopath could, honest to god, slap people with his enormous hands and transport them to other universes. What has his life come to?
He jumped, attempting to grab the villain's arm (his alias was Lord Universe, which was even lazier than Aizawa's own hero name), with his capture weapon, only for the man to use said weapon to pull his arm and launch Aizawa into the air.
Not for the first time, he was grateful for his Erasure when Lord Universe failed to use his Quirk into Aizawa.
Then, Universe kicked up the dust from the ground and punched his stomach.
Aizawa closed his eyes as he coughed up blood. Next thing he knew, a blue and violet portal was transporting him to who knows where.
"Well shit," Aizawa whispered, just before losing consciousness.
Nezu was going to find a way to bring him back, purely to murk him with his own tiny paws.
_____
"FUCK HIM! I CAN'T BELIEVE HE JUST LEFT LIKE THAT!"
Aizawa opened his eyes, perhaps because of the screams, but most likely because of the earthquakes that followed them.
Great, he was laying in some kind of abandoned area (something that was easy to tell, given of the lack of scared shouts from civilians... or corpses), without any kind of backup, and he was severely injured.
God, his body felt like it got hit by a truck five times in a row (he would know, that happened to him twice), and all the noise wasn't helping his migraine.
Aizawa turned his head, spotting a short man with pumpkin hair in the middle of an obvious break-down.
He looked a few years younger than Aizawa, and particularly heartbroken.
"Damn you Dazai!" Another earthquake followed his curse. Oh, he was making everything around him tremble. Without even trying, Aizawa would like to add.
Everything was bright red, buildings were falling down at the same time some big ass rocks decided to levitate, the floor was full of cracks and craters, and the young man seemed to be losing control of his Quirk... if that was what they had in this new, unknown universe.
Oh dear, he actually wasn't in his world anymore. Shit, OK he would have to have his existencial crisis later.
(He should probably be more bothered to begin with, but Aizawa has seen some shit already, and what was happening now wasn't particularly crazy... for him.)
Aizawa coughed and attempted to sit up when red lines started to form and circle the redhead's arms, making said man panic out of the blue.
"No, no, no, not now!" He stood up from where he had been kneeling at the ground, kicking the empty bottle of Petrus that was next to him in the process.
Aizawa didn't need any more clues to use his Quirk, cancelling whatever power was affecting the redhead.
The man chocked in surprise, then moved his dazzling blue eyes (they were extremely similar to Nemuri's), to look at him, making an incredulous sound after seeing his Quirk active.
"How-? Another cancelling ability?" He seemed to try to mumble to himself, but his voice still reached the pro hero.
Then, he seemed to notice Aizawa's injury, making him gasp and run, fast, to him. "Wait, don't move, I've got you."
Seeing the man's genuinely worried face, Aizawa decided that it was the perfect time to stop using his Quirk, and pass out. Again.
_____
When Aizawa woke up once more, he felt better than the last time, and way more comfortable. Honestly, the bed he was tucked in was so soft he thought he would melt.
He opened his eyes, noticing the white ceiling and walls. He most likely was in some kind of hospital, which explained why he was so sleepy, and clearly high on anestesia.
"You were out for two weeks." A voice spoke next to him, quietly. "You will have to stay here some more time, though, your ribs aren't in the best condition right now. Luckily, you didn't puncture any organ."
Ah, it was the redhead from before. He looked better, calmer, and his eyes weren't bloodshot from crying anymore.
"Who are you?" Aizawa rasped out, his throat felt like a desert.
"Nakahara Chuuya." Nakahara gave him a glass of water with a pink straw, one of those with more loops than necessary that kids loved to use. Aizawa decided to go with it.
"Aizawa Shouta," He said, once he gulped down the liquid.
Nakahara smirked. "Good to know, we couldn't find anything on you, which is extremely strange." Then, he added almost in a whisper. "You are lucky the Boss is more than interested in your ability".
Aizawa furrowed his eyebrows and grumbled. "We? Boss?".
What did he get himself into?
"Tell us who you are, and then I will answer anything you want." Nakahara offered, waving a gloved hand at him.
Aizawa sighed, he didn't really have any other alternative, did he? At least Nakahara seemed honest, and it wasn't a bad deal. Besides, the redhead did get him medical attention.
"Alright, Nakahara, you win."
Nakahara's smile widened a little (he was cute, like an easily excited kitten). "Please, call me Chuuya."
_____
Aizawa learned a lot about his new universe from Chuuya.
Quirks weren't a thing, although some people had abilities, they also were in Yokohama, Japan... and Chuuya was en executive from the Port Mafia, a powerful criminal association.
Now he was Chuuya's new partner, since he ended up with no other choice than to join the Port Mafia and take the spot. Much to his dimay.
Apparently, Chuuya couldn't control part of his ability, For The Tainted Sorrow, and needed someone to cancel it for him in order not to die. Oh, and his former partner, the bastard Chuuya had been sobbing about when they met, had betrayed the Mafia not long ago.
"We were more than blessed to find you, you are perfect for the job after all, so we won't let you leave." The Port Mafia's Boss, Mori Ougai, had said when he refused to their offer to join. "I hope you understand."
He was able to avoid torture to "correct his attitude" purely because of Chuuya's ability to melt hearts and make his subordinates do whatever the redhead wanted. Nevermind the fact that said wants went againts Mori's direct orders.
He was still furious, though. Furthermore, he despised killing and villain activities in general, he was a hero dammit, he was supposed to fight villians on a dialy basis.
After five months of joining the Mafia, he lost it when Chuuya, under Mori's orders, murdered a detective who was determined in stopping the mafia.
Chuuya just accepted his angry accusations and hurtful words.
That's when he noticed, Chuuya didn't get any pleasure from killing. He was part of a dog eat dog world, where he didn't have much of a choice but to do what Mori wanted.
(Perhaps, he could convince Chuuya to do something, anything, to stop all this crime and suffering).
"You are better than this, Chuuya." Aizawa said, suddenly not yelling anymore. "You can't seriously tell me that you enjoy causing so much harm! I can SEE that you don't."
Chuuya perked up at that, and decided to explain himself. "Of course not! But this is my family, the Mafia is all I have, and they earned my loyalty."
Aizawa thought about it. Chuuya had told him that he had basically been in the street when he joined the Mafia, betrayed by The Sheep.
Most of the mafia just did what they had to in order to keep the money coming. They wanted to protect their people (as long as they were loyal, that is), not take over the world or "change society" (which, yeah, society was fucked up, but murder wasn't the answer, goddammit) like villains in his world did.
"... What about just getting rid of Mori, we could reform the Mafia, take it to the side that saves lives."
It made sense. With the power the Mafia held, they could make things much better if they wanted, help people.
"Fuck, Shouta, I, I don't know." Chuuya gulped. He wasn't stupid, like people used to assume because everyone was next to the damn Demon Prodigy, but strategies weren't his specialty.
"Come on, Chuuya, help me make this place better for everyone," Aizawa pressed, because Chuuya was strong, really strong, he would be an asset (and maybe because he liked the redhead a little, he was nice to be around, and had a heart of gold).
"...Fine! Fine! But you will have to help me convince Ane-san to join us."
Ah, so much like Chuuya, he wouldn't leave Ane-san behind for the world.
(It made sense, she was the one that took him under her wing, not Mori.)
"Deal, partner." Aizawa smirked, making Chuuya feel warm.
Chuuya had to admit that he had missed Dazai for a while. Well, "missed" was an understatement, but he guessed that was normal when your lover decided to disappear out of the blue, and leave nothing but a bomb under your car behind.
However, the thing was that, he only had a few days to mourn because suddenly he had been too busy trying to stop Mori from killing or torturing Shouta, and afterwards he just wanted the man to be okay, since he dragged the taller to the Mafia in the first place (curse Akutagawa for ratting him out when he saw Chuuya dragging the man to a hospital), and now they were going to start a fucking rebellion.
He completely forgot about the mackerel.
And he realized, it was alright... the betrayal didn't hurt as much as it did months ago. He also had a new partner now, one who actually showed his emotions and wasn't constantly antagonizing Chuuya, or hissing hurtful comments every two seconds.
Things were actually better now.
_____
Aizawa left flowers at the same time that Chuuya did. Chrysanthemums for peace, Baby Breaths for love, Peonies for value, and Forget-Me-Nots for respect.
All the graves were perfectly clean and full of gifts. The Flags deserved it.
"They were my best friends, you know?" Chuuya whispered, leaning on Aizawa.
The older man hummed. Chuuya loved to talk about them.
"I lost one of my best friends too," he admitted, avoiding Chuuya's gaze. "I like to think that... as long as I remember him, he will never be truly gone."
Chuuya nodded softly. "Make them live inside our hearts, and through the tales we tell... I love it."
They stayed in silence a few more moments.
"Don't you miss it? Your world, that is," Chuuya asked, he had been tiptoeing around the topic for a while now.
"Yeah... but I only had two close friends, I can only hope they are doing well."
Hizashi and Nemuri probably didn't handle well losing another person dear to them (who was he kidding? They were probably destroyed for a while there), but they were the type of people that could keep going despite everything.
(He needed to believe that).
"I'm sorry that I couldn't find a way to take you back."
"It's not your fault, Chuuya."
Chuuya hugged him.
"Still sorry," he mumbled against his chest. (The redhead was so tiny, Shouta just wanted to protect him.)
Aizawa put an arm around Chuuya's shoulders.
They stayed like that for hours.
_____
Years later, Aizawa was woken up from his sleep by his partner throwing himself on top of him.
"Shouta! Guess what!" Chuuya squealed, buzzing with energy. How did he do that again?
"What, Chuuya?" He mumbled, trying to go back to his dream, he had been in a world where he was a shiny yellow caterpillar, lazing around under the sun.
He wanted to go back. Please.
"Gee, no need to be so grumpy, it's already ten in the morning." Chuuya poked him "Besides! I have a gift for you."
Aizawa then felt a fluffy something in his face "Meow~."
Chuuya watched, with amusement, as Aizawa sat up (with Chuuya on top of him and everything, because Shouta did exercise, thank you very much), to pick up the animal with his hands.
It was a tiny, white burmilla cat with big golden eyes.
"You like her? I found her abandoned in a dirty alley, so I washed her up, her name is now Dolly!"
Chuuya beamed at him. Ah, Shouta wondered where were his sunglasses when he needed them.
"I love you and our new baby," Aizawa said, with a completely monotonous voice.
"Fuck yeah! I knew you would love her, come on put a shirt on or something, I made pancakes with chocolate chips and whipped cream." Chuuya tugged his arm. "Oh, and black coffee with no sugar and hot as hell, just the way you like it."
Ah, yes, this was the reason Chuuya was the only one who managed to pull him apart from his wonderful bed.
They spent the rest of the day introducing Dolly to their other seven cats (they both had a thing for rescuing the little animals, sue them), and to their adopted street dog with a prosthetic leg that knew nothing more than giving love to everything that moved, Hoshi.
(Aizawa wasn't a dog person, but Chuuya adored the happy things, and, contrary to popular belief, he wasn't heartless.)
Chuuya decided to take the day off, so he never visited the Mafia until the next morning.
Therefore, Dazai Osamu spent hours waiting in the dungeons of said organization, wishing to see his pretty ex-partner once again.
Sadly, said partner had a life of his own, and wasn't waiting around for him to come back.
