Repent

Aldera High wasn’t the best place ever, but it worked for them.

School started rough but Izuku was a great learner and he always kept his notebooks on hand, not like he had anywhere to put them otherwise.

The ridicule was second nature to him, and mostly it all went smoothly.

Mostly. There were two hiccups in his plan.

Firstly, an ash blond that used to know him is still at the same school and he has been avoiding him like the plague, and people are starting to notice.

Second is the person following him and his sister home after school the last few days. 

He wants to put a stop to them. He’d thought it could just be a coincidence at first, but they have followed for days now. Can he act without being arrested? He was only 16 and still needed to get into UA,two more years without confrontation.

Although luck seemed to be on his side when he took the turn down his normal ally to get to his ragged apartment faster. The person that was tailing them cut into the alley too late and he took off running around the corner dragging Himi along and stopping out of sight.

Soon enough the brown trench cloak clad woman turns the corner and trips when she passes them. “You knew I was tailing you?” she asked.

“Yes, now answer why you were, we haven't done anything wrong.”

“That's a lie, and we all know it, but we are thinking of letting you off with the career you two are trying for. I was meant to tail you to make sure you were really trying to become heroes just to save people. But, well, it looks like you caught me.” she sighs before picking herself up and taking off the hat and trench coat.

Light blue hair falling to her shoulders as the ends twist into spirals. Her sapphire blue eyes have white pupils, her face was kind… and really young. “Year one UA student Nejire Hado! Also known by my hero name as Nejire-Chan! I took spying on you two as an extracurricular on espionage… that I just failed.”

“So you're a UA student?”

“Yup! Oh now that you know who I am, can I ask you questions? I've been wanting to ever since I first saw you two. Like, what's your quirks, or how is your apartment? Are you two dating or is it a platonic relation? Do you two have families?” Nejire rapid fires off the questions.

Izuku answers back in the same order. “Not going to tell that to someone we don't know; it's not too bad, we’ve had worse. No, we are more like siblings and not besides each other.”

“.... can I see your apartment?” she asks.

They somehow end up letting the woman into their home without much trouble, only for her face to fall after seeing how the two are living. “This is mediocre at best. You don't even have food besides ramen!”

“We get what we can.” Izuku sighs, his tusks collecting moisture from his breath.

“I refuse!” The bluenette says.

“Refuse what?” Izuku asks, cocking his head to the side.

“I refuse for my two new siblings to live like this! I'm going to pull some money and renovate this place! I'm going to have to get Mirio and Tamaki in on this but you'll have a better home soon enough!”

“Did you just forcibly adopt us?” Himiko says.

“Yes! Now I'll be back soon! Eat dinner, we have some work to do when I get back!” With that she walks out the apartment with 100 ideas and a goal.

Three days… It took three days for them to finish the work.

The newly painted walls and a brand new dining room table, hardwood floors and the cots that they had now replaced with beds with pillows and comforters. 

Food newly stocked and replenished and a recipe book set up for them, a whole year's worth of rent paid much to the landlord’s dismay. No matter what Himi and the 3 UA students say, he definitely wasn't crying when they first finished. 

“So you two wanna be heroes?” Mirio asks as he cooks lunch for them all.

“Yeah, to prove that there is no such thing as an evil quirk.” Himiko says.

“Hmm, Nejire, you're thinking what I'm thinking?” he asks the bubbly girl as his best friends play Mario Kart 8 from an old switch. Something Mirio just had lying around.

“Yeah! Let's do it!” the bluenette yells, throwing her arms in the air.

“Do what?” Izuku asks, slightly confused. What more they can do for them?

“Train your quirks of course!” Mirio says.

“... I might have a few ideas then.” Izuku says, pulling out a notebook.

(interlude brought to you by chibi Izuku and Mirio brainstorming ideas)

Izuku and Himiko finish the clearing, making a ring just big enough for two people in the trashed beach, Mirio made a decent schedule for the cleaning and fighting with quirks letting them finish the beach by the end of this year, and then race the last year with purely training quirks and fighting. 

It seems almost barbaric when Izuku and Mirio fight, and that's not in the Oni’s favor at all. Mirio is relentless in putting Izuku into the ground. The lanky Demon gets up only to be tossed to the side like a rag doll.

It makes him angry. 

Very VERY ANGRY.

Izuku throws a punch, and it's faster than anything he has done so far, it still misses but the action surprises everyone but Izuku who is seemingly in a blood rage. Punch after punch trying to hit the blond that just lets them pass through.

Izuku, while angry, is still analytical and watches for a pattern and finds one thing he can use. Mirio can't see if he uses his quirk on his head. So Izuku aims a large right hook for the boy's face, and follows through using the momentum to bring his left leg up, connecting where no man wants to be hit.

“AAHH!” Mirio screams as he drops.

“Did izuku just…” Nejire starts.

“..he did.” Himiko says in disbelief as what stands in front of her.

Tamaki says nothing but anyone can see the pain on his face.

“He transformed… and kicked me... in the family jewels.” Mirio said breathlessly into the sand.

Wait… transformed? Izuku looks around for a mirror and finds an old car. Looking at the rear view mirror he finds a new face looking back. It’s still him but different. His skin is yellow, not the normal green and he has grown a bit about the same size as Gunhead. And his tusks, his horn that adorns the left side of his head and claws have all sharpened. 

“When did this happen?” he says as he calms down and drinks some water, before turning back to his normal green state.

“When you started punching like an angry Doom Slayer.” Tamaki says as he gets what just happened. “This is your first time doing that so I have a question for you.”

“Ask away.”

“What emotion did you feel when that happened?”

“I… was angry that I couldn't land a hit.”

“Have you ever been angry like that before?”

“Not really? Wait, are you saying that my strength comes from my anger?”

All of Tamaki's built up courage was spent. “Um...yeah … that..” he hides again.

“Hm, so while the strength does matter it will help Himi more while controlling this transformation and learning how to fight will help me more. Can we adjust the training for this?”

Mirio looks up from his place on the ground. “Sure… just no more nut shots. I want to have kids at one point or another.”

“Noted.” Nejire says under her breath.

“What?” Himiko asks.

“Nothing.” the bluette says bouncing back and forth.

“Toga, get back to cleaning, it will take you longer now that me and Midoriya are going to fight a lot more than clean.”

“Yes Togata!” Himiko says getting back to work.

“Now Midoriya, show me that form again.” He punches the boy in the face and watches yellow spots appear and spread as the boy bulks up again.

(interlude brought to you by chibi yellow Izuku and Mirio sparring while chibi Himiko clears up trash in the background)

“Fuckin Demon, i dont care if you have a strong quirk, you’re just a villain waiting to happen.” the ash blond says in Izuku's face.

“The same can be said about the walking time bomb that thinks he can do anything he wants. You do know quirk discriminationis not only illegal but will get you kicked out of UA, right?” he retorts, not waiting for a response as he pushes past the blond. With a few more barbed words. “I would know, I am training to be a hero.”

That set off the fuse on the blond. “I'M GOING TO BE THE ONLY PERSON FROM THIS SHITTY SCHOOL TO GET INTO UA, YOU DON'T STAND A CHANCE. YOU OR YOUR DUMBASS QUIRK!”

Izuku felt a pang of anger at the mention of his quirk, But his training stopped him from transforming against his will. The last year has been hard on him with the training and studying from the now second year students of UA.

But the blond has been the worst part, they were put in the same class and Izuku hated it, the moment he found out his quirk he went off. The blond can't recognize him from their childhood, then again it's not like he has seen him since his quirk manifested.

The fake name Midoyin Antaki helps, but he still fears the moment his old friend sees what he has become.  

The blond turns away and is asked if he wants to go to the local arcade.

“You all know I go to the graveyard on fridays.” He says a lot more somber than anything else Izuku has ever heard from him.

“Hm, why do you go to the graveyard?” Izuku asks before he can think better of it.

“Why the fuck do you wanna know! To use it as ammo against me?!”

“No” he says without hesitation. “I.. know how it feels to lose everything.”

“Tch, yeah, right. You probably have everything handed to you on a silver platter and are just trying to get under my skin, dem-”

“I lived on the streets after my parents were killed by a... villain. I refuse to let him win by giving up. Thus, I am becoming a hero.”

Bakugo waits a moment looking over his shoulder to look at the greenette “.... come with me, then.”

The walk to the small cemetery was not long, but when they stopped in front three graves, the oni was taken aback. “How did they die?” Izuku asks, tension throbbing in his shoulders as his ex-best friend stands in front of a grave with his own name on it.

“Ha, a corrupt hero killed them without remorse. We were never given an answer on why. Killed my best friend and his parents…. I'm sorry for being hard on you, but I can't… I can't afford to be weak... not again.” 

“It's not your fault.”

“Yes it is. I never checked up, or helped, or, fuck, even tried to get close to him again. I could have made a difference. What if he was at my place at the time. Or on a home call? He wouldn't have died. He would be here now, not down there.”

“Ha, that’s funny.”

“Did you just laugh at..” the blond sees red and punches the demon boy full force.

“Don't take it personally. But what you said was funny to me.” Izuku smirks at the rage in his ex-friend’s face.

Katsuki punches him again and firecracker explosions erupted from his palms as the two started to fight.

“Guess we both need this out of our systems before we talk.” Izuku raises his fists as he bulks up much to the blond's surprise, even if that surprise is short-lived. An explosion hits him in the gut and Izuku punches the blond in the face, breaking his nose.

An explosion cuts through his clothes and Izuku lands a hit on the blond’s stomach, a flurry of blows traded back and forth. They were on even ground they both could see it. That's when Izuku spoke again.

“You think standing here is helping him, anything that will help him is to find someone to help. That's how he was right, always eager to help others?”

“SHUT UP!” The biggest explosion hit him in the face and Izuku has it at that.

“NO! I CAN'T WATCH YOU BERATE YOURSELF FOR SOMETHING THAT'S NOT YOUR FAULT!” He feels anger seep into every word and his skin stretches as if to fill in for something. He looks at his hands and finds they are bigger and have turned red. An ache in his bones as if they are heavier than before. The deadly black claws look like something from a horror movie.

“I WON'T LET YOU LIVE LIKE I DID, KACCHAN!” The name passes his lips and he knows he fucked up.

The blond freezes and looks at Antaki again. “Izuku?” he says hopefully. The tears that prick the blond’s eyes don't suit him at all.

“Don't you dare cry, because if you cry I’mma cry and then we both will be a mess in front of my mother's grave.”

“You're standing on your own.” A ghost of a laugh passes the boy’s lips and Izuku looks down. 

“Oh wow, like I didn't already look like a horror movie character now it looks like I'm coming out of my own grave.” he says with a smile as he drops to his knees and turns back to the blond as he shrinks to green again.

“You... is this why I never saw you after…”

“My mother was ashamed of my quirk and devolved into abusing me, and my father was a villain. I called the heros and jumped out the window. Lived on the streets for years, youd be surprised how few people give a fuck about someone like me.” he gestures to his demonic featers. “Though There was one person that helped me at my lowest and I'm ever indebted to her.”

“Oh? Is that a blush from the demon?” A snide smirk finds its way onto Katsuki’s face.

“I.. it's not like that!. She just.. If it wasn't for her I wouldn’t have found my sister or made it back here. For almost a year she helped by bringing me food and clean water.” The blush only darkens against his light green skin; the darker green setting is almost like paint. 

“HA! You'll have to pay her back when you're a hero huh?” the blond teases as his thoughts spin. ‘I have to be better, most people don't get a chance like this.’

“Shut it!” the greenette buries his face into his hands.

“Sure, but we should go by my place. I'm sure mom will want to see you. After so long, I don't even know how she will react.”
