A stray hero (student)

Summary:

The villain placed his hand on the backpack Shinsou was holding and pushed him back. Just a shove really. Shouldn't have been a big deal.

 

So why was he surrounded by clouds now? The small portal that he can see the villain inside of above him was disappearing.

 

And he was falling.

______

 

Or. Shinsou hitoshi is in the mcu.

Notes:

This is my first fic ever btw so if it's not very good I apologize. I'm still trying to figure out how this works.

Also the writing gets better as it goes on. I will re write it once it's done.

Chapter 1: Unknown villain

Chapter Text

Shinsou hitoshi: second year UA highschool hero course student.

Age:16 years old.

Eye color: purple, with white pupils.

Hair: purple, wavy, does not obey the laws of physics.

________________

 

Today was supposed to be a normal day of hero training. Hitoshi was sitting with a few other members of his class when aizawa had told them they would be going off campus for today because nezu insisted they needed some real experience (despite already having their internships) so they were brought to a fight with a minor villain.

Now that he thinks about it, they probably shouldn't have brought students to a fight with a villain whose quirk was unknown, even if they're second year's.

______________

 

"I wonder if we can convince Aizawa to not expel us for not calling a hero over." Kaminari said with a nervous looking smile turning to look at hitoshi.

 

"He's not even going to suspend us, he's probably just going to make training more difficult for like a week."

 

Shinsou was not happy with the outcome of the fight. Him and kaminari got separated from the rest of the class when a newer hero attempted to use his quirk on the villain without a proper plan and ended up collapsing a smaller building behind the guy.

He doesn't even know what the hero's quirk is but it caused some damage and Kaminari ended up dragging Shinsou to help evacuate civilians from the area.

 

Shinsou and his too happy for their current situation classmate walked into a smaller crumbling building next to the collapsed building to help evacuate while the rest of their classmates looked for the villain who disappeared after the newbie hero attempted to use his quirk on him.

Him and his classmates weren't there to fight the guy anyway, they were just supposed to watch the heroes do their job which they failed miserably at. Crazy coincidence that the building they walked into was the one the guy was hiding in and hitoshi ended up with a busted arm after trying (and failing) to capture him which resulted in the man using a small explosive that caused part of the roof of the building they were in to crumble sending debris right onto shinsou.

 

Kaminari came out unharmed though. Because of course he did.

 

They were now walking back to tell aizawa that kaminari let the guy get away by accident and shinsou probably needed to see recovery girl when they got back to UA because in kaminari's exact words "Your arm got hurt because I brought us in there so I should take the blame for him getting away! It's only fair! Besides, you need to see recovery girl anyway. I'm pretty sure you have some sort of disease because those eye bags can't be normal."

 

"I don't have a disease, dumbass. I'm just tired." He said with an eye roll as they rounded the corner to where a few heroes including Aizawa were gathered.

 

They didn't even make it 20 seconds before Mandalay who was talking to aizawa turned to them looking horrified (ok maybe his arm was worse then he thought)

 

Mandalay pointed to them and Aizawa finally noticed their presence.

“What happened to your arm?”

 

“It was kaminari.”

 

“Dude! at least get me get the story together first” kaminari grimaced

 

“You had this entire walk to get the story together.” He said turning to kaminari with one eyebrow raised.

 

“What happened?” Aizawa said, interrupting his students' bickering.

 

“Ok so you know that villain dude who we literally just lost and everybody else is looking for right now? Well he was in the building we walked into and we very bravely fought him and then he caused an explosion with like a bomb or something and a giant piece of the ceiling fell directly onto shinsou and he might need to see recovery girl." Kaminari rushed to get everything out.

 

“I think you forgot to mention you were the one who dragged us into there” didn't Kaminari just say that he would take the blame?

 

“Oh yeah uh that too,” kaminari said, smiling nervously once again.

 

Aizawa sighed heavily and it looked like he was about to say something else before iida, kirishima, and bakugo who had been searching together returned holding a small bomb looking device. One that looked like it had already gone off.

 

Mr.Aizawa!” Iida said running over “we encountered the villain a few blocks away! He caused an explosion using this device! It doesn't appear to be working anymore so we think it was a bomb!”

 

“Gee a device that explodes I wonder what else it could be.”

 

“Shinsou I don't think this is the time for sarcasm” Mandalay looked at him with a serious expression.

 

“Wait, you said a block away? Man that guy's fast as hell because he was just in that smaller building over there.” Kaminari looked surprised.

 

“Oh maybe he has a speed quirk!” Kirishima pointed out before bakugo talked over him “Well he has some sort of transportation quirk obviously he literally disappeared earlier shitty hair use your brain” bakugo looked absolutely pissed which shinsou assumed was from the guy getting away. Looks like they have something in common today.

 

“There are other heroes here looking for him. You weren't brought here to fight him, go get the rest of your classmates so we can head back to UA.” Aizawa said and Mandalay agreed by nodding her head.

 

“HUH? You said we were here for experience but we don't even get to help take the guy down! What the crap!” Bakugo practically screamed as always. God he needs anger management classes.

 

“you should listen to your teacher” they heard a voice from behind them causing them all to turn around. Endeavor was holding an unconscious man with spiky White hair by his shirt and dragging him over. He had caught the villain while they were over here doing nothing. Great..

 

“Hey endeavor caught him awesome!” Kaminari looked more than relieved to be able to head back to UA.iida also looked pretty happy he was caught, while bakugo just looked pissed.

 

“We should go gather our classmates now-”

 

“Wow shinsou what happened to your arm?”

 

“Shitty hair and me will go get raccoon eyes. Dunce face go get deku”

 

“Oh I was going to go with shinsou to see recovery girl once we got back to UA so I'll just stay with him-”

 

“Kaminari, go help gather your classmates. I'll stay with Shinsou. We need to talk anyway.” Aizawa definitely wasn't happy but he didn't seem like he was about to lecture anyone so Shinsou was content with staying with him.

 

Shinsou tuned out the rest of what they were saying as Aizawa walked him over to a small area where some civilians were gathered recording endeavor holding the villain who probably should be tied up by now.

 

“You need to be more careful.” Aizawa started turning to look at his student. “You should've come and gotten a hero before jumping into a fight with somebody whose quirk you don't even know.”

 

“I am a hero.”

 

“In training.”

 

“Close enough”

 

 “Shinsou.” Aizawa deadpanned. Which wasn't fair on Shinsou's part. He technically was a hero. He had his license even if he got it later than the rest of his classmates. He will be a third year student next year anyway.

 

“I wasn't even injured that badly. I sprained my arm at most.” he said which isn't technically a lie. It doesn't hurt that bad so it probably isn't broken. “Your entire arm is bleeding” Aizawa was starting to look slightly annoyed as they walked towards the bus.

 

“My entire arm is not bleeding. Only part of my arm is bleeding and that blood just happened to drip down my entire arm.” that also wasn't a lie.

 

“You're lucky you got your hero license recently. I would have had to call tsukauchi if you didn't. Had him arrest you.” Aizawa said as they walked onto the bus which was clearly a lie. Shinsou could kill somebody and his teacher wouldn't tell anybody. Partly because his teacher is also his foster dad but that's besides the point.

 

Aizawa sat in the very front and left shinsou to go all the way to the back and sit down next to his bag. Now that his body is relaxed his arm is starting to hurt significantly more. Ok maybe it wasn't just a sprain. Shinsou grabbed his backpack from beside him and put it on his lap. He didn't know why it just felt right.

 

He was almost completely relaxed when there was a loud boom outside the bus with a bright light. He covered his eyes with his hands for a second before following Aizawa who had ran out moments before.

 

He looked around and saw 3 things.

1: villain guy was awake (and still not detained seriously what is up with the hero's today)

2: villain guy had bombs.

3: nobody was moving towards him.

 

Shinsou looked over to aizawa who had pushed him back slightly before he heard Mandalay's voice in his head.

 

“ We found out what his quirk was. It wasn't explosion related despite having explosives on him. Nobody moves forward; he can make portals for himself and he could disappear in an instant.”

 

Shinsou assumed everybody here got that telepathic message based on Mandalay saying nobody move instead of just don't move. The villain whose name Shinsou still doesn't know was looking around frantically, probably because he woke up from being knocked out cold. He was making eye contact with everyone for just a moment and everything felt tense as he locked eyes with Shinsou. Bakugo looked like he really wanted to just explode the guy, kirishima looked like he had been right next to the bomb when it went off, and Kaminari was helping a civilian far back. Yamada showed up a while ago apparently because he was next to ururaka and iida. Why was he taking note of his surroundings again?

 

There was a noise behind him. Like something opening up. He couldn't really focus on it though. It seemed hard to focus for some reason. Is it windy? He thought it was a nice day out before but it's pretty cold right now.

 

He turned around for a moment and he didn't see a sidewalk and buildings surrounded by heroes and civilians. He saw the sky. He wasn't looking up, which was weird. Before he could process what he was looking at he turned back around and saw the villain running at him full sprint. Aizawa was further away than before but he was running at him now. A lot of people were running at him now.

 

The villain placed his hand on the backpack Shinsou was holding and pushed him back.

 

Just a shove really. Shouldn't have been a big deal. So why was he surrounded by clouds now? The small portal that he can see the villain inside of above him was disappearing.

 

And he was falling.
