A hero of justice [My hero academia x Shirou Emiya]

Waking up in the infirmary Shirou looked around. Shoto lay unconscious in the bed opposite him. A few other classmates including Midoriya and Bakugo were here as well. "Your up already dearie?" Now recover girl was shocked, she'd never expected Shirou to recover this fast. In fact, his body looked stronger than when it was first damaged?! Like iron tempering itself in only the hottest of flames. "Yeah, I always healed faster than anyone else. I reckon it's simply a byproduct of my quirk." Shirou smiled and got up throwing on his uniform and making his way back to class.

Kirishima was the first to approach him. "Woah, dude! That fight of yours was totally manly!" Shirou smiled as a few other members of the class came over to check up on Shirou. "Are you okay, ribbit?" Tsu said unconscious making a frog-like noise. "Yes I'm fine I heal fast. Anyway, what happened when I was gone." Shirou asked his classmates, "nothing as cool as the fight between you and Shoto, but notably, Momo beat her opponents easily on her own. "Your sister is really scary... she summoned swords and shields all around her that made fighting her impossible. Quirks are meant to have weakness but she's just too perfect." Jirou was terrified of her.

When they battled it couldn't even be called a fight. Rather she and Kaminari got slaughtered. "Don't worry about it, she's not that bad of a person. Just competitive." Shirou walked and sat down. Jirou didn't feel even the slightest better though.

Soon the others who were injured throughout the day came back into the class. Midoriya was first, his arm being in a large cast. Soon after Bakugo arrived silently seemingly contemplating something. Shoto was last, he was in his normal silent mood. But he gave a thumbs up to Shirou as though fighting they'd bonded together.

The day eventually came to an end. Shirou and Shoto were going to walk back together, their houses conveniently were nearby. But they stopped in their tracks when they heard a conversation.

"Kacchan! Wait up!" Izuku shouted running towards Bakugo who had begun to leave. "What do you want..." Bakugo was obviously enraged at the day's occurrences.

Bakugos anger scared Izuku and it was obvious he struggled to say what came next. "There's something I have to tell you, maybe then you'll understand what's been going on... I wasn't hiding my quirk from you. It was given to me by someone else. Recently."
Izuku took a step back and Bakugo looked genuinely surprised.

"But I can't tell you who so don't ask! I know it sounds like something out of a comic book, only it's real. The thing is I don't really have any control over this power yet, that's why I caused that tornado today. I haven't figured out how to make it my own...

But I'm trying, that's why I tried not to use it against you in the exercise. But in the end, It was the only chance I had of fighting!" Bakugo was shaking in rage now. Shirou was even worried for Izukus safety and prepared to trace a weapon.

"I'll work until I have full control over this borrowed quirk. Then I'll finally beat you with my own power!" Izuku looked up and began to blatantly panic, to Shirou it looked like he said more than he meant to.

"How dumb do you think I am?! Borrowed power? Don't talk to me like I'm a complete idiot. You already made a fucking fool out of me in that training exercise... So Did you come to rub it in!?

I lost! And to make matters worse it was too fucking you of all people! I came in first in the exam, but even that's not enough! When I was watching the sword-fucker and the ice guy in the fucking hospital. I realized I couldn't beat them in a head to head fight! Crap! I would even lose to that pony haired girl!

Damm it! Damm it! Damm it! You won this round Deku. But I will be the number one hero! I WILL NEVER LOSE AGAIN, NOT TO ANYONE.

SO DON'T EVEN TRY!" Bakugo turned around and stormed off.
