Crossover story idea – Hibari Kyoya is Quirkless, but still Hibari fucking Kyoya. His claim over the city he lives in is complete before he hits middle school, and he decided to become a Hero if only because it was a quicker way to getting the world under his hand than being a villain. He enters UA, dominates everyone and their expectations, and then laughs in the face of it all.

Note this is the reason I chose Himura for Kyoya's 'new' surname; From Japanese 緋(hi) meaning "scarlet, dark red" and 村(mura) meaning "town, village".

There were many things in this world that Himura Kyoya considered worth his time. Biting disobedient herbivores to death? Worth it, especially if they fought back. Keeping his town in line? Also, worth it, because he got to bite herbivores, duh. Becoming a Villain? ... no. Probably. If only because he liked the thought of justice and peace rather than pathetic minions following his every word.

He chanced a glance at his second in command, watching as the creature (that bore a striking resemblance to his original second in command, Kusakabe, in his real home town Namimori) bossed around a small army of reformed delinquents to do Kyoya's bidding.

… and you really need a 'Hero Licence' to bite herbivores to death here. Apparently.

Kyoya listened as Kamikiri Tatsuya (even his name was similar, weird) gave the final words of his speech to some 30 or 40 young teens and pre-teens, before a nearly deafening roar of approval came from the crowd. Kyoya looked on in distaste, taking in their many various 'Quirks.' Some were very visible, like the black-feathered wings of his second, and some weren't. Everyone just assumed that this was the case for Kyoya.

They were so sorely mistaken.

(Poor bastards.)

When Kyoya was 4 he had been told that he was born Quirkless. His mother cried. Similarly, his father was upset. His doctor couldn't believe it, as this seemed to be his first real case of a child being born Quirkless. Kyoya wasn't sure what was going on, so he just sat and glared at people until someone gave him his stuffed bird plushy back. (It was big, almost half his size, a bright yellow, and for some reason, Kyoya couldn't sleep without it. He named it Hibird.)

When Kyoya was 5, he was bullied for being Quirkless… for two minutes. He bit them to death, harshly. Kyoya literally bit one kid on the hand. That same night, the memories started; memories of when he was someone else with a similar name. Someone who used the same words that had floated out of his mouth unconsciously (For crowding and being loud herbivores in my presence, I'll bite you to death!). Someone who lived in a small town just like his but grew up with very different parents.

Himura Kyoya was 10 when he amassed his memories of his past life, of Hibari Kyoya, in full, including his tonfa and Cloud Flames. He found that as he was he couldn't ignite his Flames, but he could still wield a tonfa better than anyone this world knew. Kyoya was also 10 when he started this world's Disciplinary Committee. He found Tatsuya before he remembered his best frie-… original second in command so the resemblance wasn't something Kyoya had specifically sought out for. Honestly.

Kyoya was 11 when the town fell beneath his rule.

He was also 11 when the police came to his door and told his parents what he was doing. He was sent to a phycologist to make sure he knew the difference between right and wrong, and that he wasn't likely to become a Villain. (They deemed him all clear, and Kyoya was actually thankful for all of his Sky's 'Moral Teachings' in his first life. It was only thanks to those that he was able to act 'properly' and not bite the herbivore to death.)

Kyoya was 14 when he decided he was going to become a Hero (to the great joy of all those terrified by him in his town). However, there were many obstacles when it came to becoming a Hero, other than needing a real moral compass. Many things like, which school should he go dominate, should he go for the biggest one in the country, or try for one closer? Should he wait another year, or rush to get the application ready in less than a week's time? Oh, and then there was the biggest one of them all.

Kyoya went to the school closest to him first, 'just to look around'. His application was denied almost instantly. Why?

He had no fucking Quirk.

He was denied a role as a Hero, because he was born Quirkless…

Kyoya very calmly walked away from the burning building and the screams of those around it, (no one was injured, Kyoya was sure of that. He wanted to be a Hero after all, and he couldn't go actually killing people if he wanted to be a Hero, sadly.) and strolled right up to the principal. The man was on his knees, jaw dropped as he took in the destruction, (thankfully) silent as he cried, and he watched his years of hard work go up in plumbs of black smoke.

"Yes, I'm Quirkless. What of it?"

The world, pro Hero's, Villains, and civilians alike, took a collective pause to shiver in fear.

To monitor him and assure the world he became a Hero and not anything else, Kyoya was allowed to enter U.A. High school; which was the only school that allowed Quirkless students to enter and become Heroes. That still meant that he had to pass the entrance exams, which began in a month's time.

And that was what the not-Kusakabe was giving his speech about. The fact that Kyoya was leaving, and that that meant they all needed to pick up where he left off and to keep the town in perfect order. Kyoya felt like laughing at them all. He didn't through sheer will power.


The idiotic herbivores were crying as he boarded the train to take him to his new living quarters near U.A. and Kyoya ignored them as Kamikiri gave one last bow in respect and the rest of the baaing and bawling sheep mimicked him. Kyoya had his headphones in and was sitting in his seat before they stood properly again. The train took off and Kyoya fought back the hebivoreic notion that he was going to miss them.

Because he wasn't.

He wasn't, ok!?

Kyoya spent the next hour asleep, and not at all worried for the safety of his herbivores. (He had trained them for events like this, after all.)


Kyoya strode confidently passed the front gates watching as a young male herbivore tripped on his own two feet. He waited for the boy to plant his face into the ground, if only because he like watching others suffer, when he was caught by seemingly nothing. Kyoya looked at the girl standing beside the boy as she wished him good luck on his first day, and he inwardly sighed. No blood before the exam… it was a sad start.

Listening to 'Present Mic' was… an extreme experience. One he thought he wouldn't have to go through again after leaving his first life behind. Was that really Ryohei, or was it another coincidence like Kamikiri? Kyoya vowed to never find out – he wasn't sure his ears could take it. All the students were sent to certain blocks, as indicated on the letters they got when they arrived – and told to destroy certain robots. Kyoya could barely contain his excitement – they looked like fun to bite to death! – and looked to his side, watching the boy from earlier look steadfastly at the gate, as if in anticipation and determination. It didn't matter. Kyoya was going to get the most points.

It wasn't him boasting – it was Kyoya stating a fact.

The loud herbivore that had interrupted the presentation (and really, he could have also been Ryohei) called out the first young male herbivore for stupid reasons Kyoya couldn't be bothered with listening to, but then Present Mic said 'start' and Kyoya took off without looking back, gripping his tonfa tight as he passed the gate. The first three robots to fall beneath his tonfa were all three pointers, and Kyoya wondered if he was actually supposed to keep count on his own.

Throughout the following 8 minutes, Kyoya amassed a staggering 89 points, and then biggest robot he had ever seen, this life time or the last, was released onto the unfortunate souls that may or may not become his 'classmates'. Kyoya grinned as he watched the others run away – not that he could blame them. The thing was massive, worth no points, and was nearly impossible to defeat.

Kyoya wanted to bite it to death.

He was beaten to the punch, as it were, when the meek looking male herbivore, the one that had tripped over his own two feet in the beginning, jumped for it. And he jumped almost (almost) higher and faster than Kyoya's eyes could track. The dust settled and Kyoya looked down to see the girl herbivore that he was speaking to before trapped by rubble near the base of the giant robot. Realization dawned on him that this was a Hero's exam; of course there would be other points, hidden points, that would be earned by rescuing someone.

With that in mind, Kyoya darted forward and lifted the large piece of rubble off the girls' leg as he pulled on the back of her jersey to dislodge her completely. Still holding her up by the back of the neck, much like a cat, he darted away, dropped her a safe distance away and turned back –

And watched the meek little herbivore deliver one of the most devastating punches he had ever seen. It literally blew the robot away! Kyoya watched the boy start to fall and watched him start to panic. He didn't know how to land… the sleeve of the boy's jersey had been blown away with the power the boy held, and his arm was purple, and by the way it was wiggling in the air with his free fall, Kyoya realized his arm was broken. The way the boy's legs were following the same movement as his arm suggested that his legs were also broken – so, it wasn't that he didn't know how to land, it was that he couldn't land.

Kyoya darted forward again, without thinking it through this time, and jumped as high as he could, his arms stretched out, so he could catch the boy in mid air. He held the surprisingly muscled boy close to his chest as he landed perfectly on the ground.

"You are…?"

Kyoya looked down at the boy in his arms, the youth reminding him of his Sky from his previous life when they were the same age, and realized he was holding onto a carnivore in the making. The boy's eyes lit up with determination and awe.

"Th-th-thank you for saving me!" he exclaimed, and then proceeded to try to wiggle his way out of Kyoya's iron grip. "But I have to get a point! At least one point!"

Kyoya raised an eye brow. This little omnivore, because he wasn't yet a carnivore, but he certainly wasn't an herbivore – herbivores ran from helping someone, therefore, most of the people in this course should be some level of omnivore… should be. – had yet to get a point? And risked his chance to get any points to rescue the young female?

Perhaps he was closer to a carnivore than Kyoya had thought.

Just as the thought passed through his head that maybe, maybe, Kyoya could help the boy – if only because he wanted to help the little omnivore grow, Present Mic's voice rung through out the battle field.

"Time's up!"

The boy in his arms froze and he turned to Kyoya with watery eyes. 'Please don't cry.' Kyoya thought with distaste, 'If you cry, I swear I'll drop you back down to herbivore, and I will never let you be a carnivore.'

The boy didn't cry. His eyes merely went white and he passed out in Kyoya's arms. He tisked and a crowd of herbivores started gathering around them. Kyoya stiffly turned and began walking to where he had placed the girl, a safe distance away, and was forced to endure her screechy voice as she thanked him – until he literally dropped the boy to the floor next to her and walked away.

He didn't need to be around for whatever was going to happen now, and he liked the fact that the moment he dropped the boy, silence finally befell the herbivores around him.


The written exam went smoothly the next day, and Kyoya would never, even under the threat of death, ever admit to the fact that he had pretended to be Sawada Tsunayoshi for that part of the exam. One question asked; 'What would you do if you saw two young adults in an argument in public? What if it looked close to a brawl?'

Kyoya almost wrote 'Bite the herbivores to death.'

Sawada Tsunayoshi wouldn't do that, and no hero would end an argument like that either. So Kyoya emanated his Sky and answered, 'I would help defuse the situation with logic and reason, and kind words.'

Kyoya gagged at just the memory of it. But, pretending to be his Sky had worked in helping him get through the written part of his exam, so… there was that.

He spent the next week in his little apartment, awaiting a letter or something of the sort that would tell him he had passed and that he would be accepted into the course. (A small part of him grew more and more anxious with each passing hour he didn't receive anything, because maybe that meant that he hadn't been accepted. After all, he was still Quirkless.)

There was a rustle at his door. Kyoya waited a whole 2 seconds before he strolled over to the door, as casual as could be – no he didn't run. He just didn't – and opened it to find a pure white envelope with a dark red wax seal, with the U.A. logo emblazoned on the seal.

Kyoya didn't do 'fangirling'… he just got a little excited. That was all.

It was heavier and bulkier than the average letter was, so Kyoya assumed that meant there was more than just a letter in the envelope… maybe he got a badge letting everyone know he was Quirkless – a type of segregation? If it was, Kyoya might really aim to become a Villain after all…

He tore the paper open and shook out the round metal ring. It was about the size of his palm, and the moment it stopped bouncing on his desk and steadied itself, a large projection covered his wall.

"I AM HERE!" It was All Might, Kyoya knew, and he immediately wanted to bite the projection to death for being absurdly loud, annoying, bright, and annoying. "I, All Might, have become a teacher here at U.A., and I must admit, Young Himura Kyoya, I have never seen a potential student get a number as high as you did, on both the written exam and the mock battle! You earned yourself 89 points from the robots and earned a fair score on the Hero Rescue Points, as well! Your written exam was beautifully composed, and you come with high regards from another Hero school." The man looked down at a paper in his hands and his eyes widened. "You're Quirkless, too?! Oh My Goodness! That's even more incredible! I welcome you to the program, Young Himura Kyoya!" The man shouted his signature laugh as he shoved a thumbs-up at the camera. "I'll see you in two weeks, in class 1-A!"

The projection blipped out, and Kyoya stood there, staring at the wall for a few minutes, realizing he may have made a mistake in his choice of school.

And maybe it was too late to back out now.

(He didn't think there would be a third Ryohei. Maybe the man's soul was brought here and broken up into several different people? It seemed as plausible as anything else…)


The school was eerie this early in the morning. There was nothing but him there, roaming the halls. Kyoya liked it. He liked it a lot. He liked it so much he almost hummed the Namimori anthem. He strolled right in to class 1-A, and took a seat nearest the back, next to the windows. He wanted to watch the herbivores – and the windows provided a wonderful vantage point. It was almost an hour later when Kyoya's first classmate walked in.

It was the second guy that could have been Ryohei.

"Oh! It's you, from the exam! You caught that other boy in mid air!" he exclaimed.

'If you say 'Extreme' once, I will walk right off the roof of this building and be done with this world.' Kyoya thought. Instead of saying all that, he nodded his head to the other boy, and looked back out the window.

"I feel you probably should not have dropped him though. That boy was already injured so badly."

"It made no difference. He was already unconscious." Kyoya responded, just to be 'kind'. "And it wasn't much of a drop." Then, just as Kyoya hoped the other would stop talking to him, the herbivore came closer.

"My name is Iida Tenya." He introduced, and Kyoya watched him extend a hand through the window reflection. "What is your name?" Kyoya took to ignoring him for a full minute, before he realized the idiot wasn't going away. He sighed.

"Himura."

At least the guy had the decency to pull his hand back after the one-word response. "It's nice to meet you, Himura-kun."

"Don't add the suffix to my name; I'm not here to make friends, herbivore."

"Herbivore?" the other looked slightly affronted by that, but just before he opened his mouth to respond, the door opened and a pack of almost a dozen students piled in together. Kyoya wanted to bite them all to death for their loud shouting and rambunctious attitudes but restrained if only so he wouldn't be kicked out. (Though the path to being a Villain looked nicer and quieter each minute…)

It was right before the bell to start class went off that the small omnivore walked in – and he looked even more like a terrified rabbit than he had all exam day. Kyoya was suddenly reminded, again, about how like his Sky the young man was. (He would never openly admit to this, but Kyoya actually missed his Sky and the man's brand of trouble.)

"I-I'm Izuku. Midoriya Izuku!" Kyoya watched the omnivore blush and look down at his feet as he introduced himself to the young girl, also from exam day.

"I'm Uraraka Ochaco! It's nice to meet you, Izuku-kun!"

"You too, Uraraka-san."

Kyoya almost gagged at the scene. Then he watched as Iida introduced himself, and then the creature from everyone's nightmares – er… their teacher came in, in a sleeping bag of all things, and introduced himself as well. He told them all to get changed into blue jumpsuits and to meet him on the training ground. (Kyoya threw up a little when he thought about putting it on. He may never be stylish or fashionable, but he had his own style of clothes. A blue jumpsuit wasn't one of them.)

They were led down to the changing rooms, and Kyoya shuffled off to the corner in an attempt to put as much space between him and the herbivores that still had to earn their status.

"Uhm!" Kyoya blinked and looked down over his shoulder, despite still just halfway taking off his shirt. It was the omnivore, Midoriya. Kyoya 'hn'ed at him and continued to take his clothes off to change. "I just never properly thanked you for saving me." The boy continued as Kyoya attempted to ignore him.

"S-s-so, um…" Kyoya heard the long inhale and looked over his shoulder again, watching the boy bow low. "Thank you so much!"

There was a long pause as everyone turned to watch, someone asking what happened, as they were in another block during the exam, and another answered. And Midoriya wasn't raising his head. Kyoya finished changing and slid on a new pair of running shoes.

"Stop." Kyoya said sternly as he turned around. "You are making a scene." The omnivore jolted up with that, his face flaming and his shoulders slouched as he looked around at the others in the room. "And don't slouch. It's unsightly."

Kyoya breezed passed the mildly shocked omnivore and the crowd watching him leave and walked to the training grounds. He was the first student there, although the teacher was standing nearby, checking his clip board. Aizawa looked up as Kyoya stepped as close as he dared – read; a good 3 meters away – and the man beckoned the teen to come closer.

"No, I'm good here." Kyoya said, planting his feet. He spent far too much time in the past few hours being uncomfortably close to herbivores – he really didn't want to be any closer. The man sighed and walked closer himself. 'Damnit.'

"You're Himura Kyoya, right? The Quirkless kid?" Aizawa asked without looking up from the board. Kyoya's left eyebrow twitched as the man stood less than a foot away.

"Yes. What of it?" Aizawa looked up with a wide-eyed blink.

"Ah, no… I just saw your score from the exams and I thought you would be more buff." There was a long pause between them as more students filled the grounds.

"Has anyone ever told you you're rather blunt? I like it." Kyoya said and he took a leave from there. Or rather, he tried to. The moment he stepped away from the teacher, he was surrounded by two herbivores, and an omnivore.

"You! I don't like you. You dropped Izuku-kun on purpose, didn't you!" the female herbivore accused. Kyoya nodded in confirmation, and the motion seemed to make her even more upset. "Why? He was so hurt saving me, and you hurt him more!"

"Eh? He dropped me?" the omnivore tilted his head, green hair bouncing slightly in the breeze.

"Would you rather I had just let him fall to the ground from the robot?"

Uraraka – what a name, really. – looked taken aback by that. "We're in the Hero Course – how could you even ask that?" she asked softly. She stared at him for a moment more before she started to pull the omnivore's arm away from Kyoya.

"Hey, wait!" Midoriya pulled his arm away and jogged back to Kyoya without looking back. "I don't really mind that you dropped me – I was already out cold, so I couldn't feel it." Kyoya took a moment to send a smug look at Iida. "I was wondering… Can we be friends? I feel like I know you, Kyoya."

"Kyoya."

Kyoya's heart jumped in his throat – that tone, just… the way he had said it; he sounded exactly like his Sky! It was almost like Tsunayoshi had been reborn into Midoriya!

Well, if Kyoya had been brought back… maybe?

He couldn't show any of this up front though. He had to keep a stony face and figure a way out of this. Or better… he was a carnivore, and if he could get his memories back from his usual catch-phrase, maybe Tsunayoshi could as well? It was worth a shot. Besides, there was something Kyoya wanted to try anyway.

He extended his hand and lay it on Midoriya's chest, right over his heart. "Listen closely, because I will only say this once. I am a carnivore, and you are an herbivore. I bite small animals like you to death. I do not have friends." With those words snarled into the young omnivore's face, Kyoya pulled away and started to pace to a far more secluded patch where he could still hear the teacher when the class began.

He could barely contain his grin though. He couldn't openly activate his Flames – sure. He couldn't light his tonfa with them. But he could still use them. Enhanced hearing and sight, prolonged use of his muscles, increased strength and speed – and of course, he could use them to feel someone else's Flames though touch. And Midoriya Izuku?

His Sky was back. Kyoya wasn't alone here.

His Sky was back!

… and how did he know Kyoya's name? Did Iida tell him? Or could his Sky be trying to force past his current self? That could be interesting, though Kyoya wasn't sure if that was safe – and given who he was talking about, the meaning of the word restraint was lost entirely. Tsunayoshi and Midoriya really seemed to be the same person after all.

(If there was one thing Kyoya took from the robot Exam, it was that this omnivore was as reckless as Tsunayoshi had ever been.)


So… this is a thing I did… wanna tell me how fucked up I am for doing this? Send me the review! Lol, but please don't hate. Also, please don't expect regular updates. I'm shit at being on time for anything, IRL or online.
