    Summary

    After an incident resulting in the King of the Underworld being returned to a young age, U.A. has a unique situation on its hands. Seeing as the Warden of Tartarus deemed it fit to leave the now-toddler on the doorstep of Nedzu's esteemed high school, the child is now technically a ward of said school, i.e. his.

    Nedzu being Nedzu -and the HPSC being shady af, the decision to keep the former-villain-turned-child seemed obvious.

    Too bad for the rest of his employees, who apparently didn't quite get the memo.

    Summary

    un·be·com·ing
    (/ˌənbəˈkəmiNG/)
    1. (of behavior) not fitting or appropriate; unseemly.
    2. the act of unmaking or reversing what is there

    A boy is recovered from the ruins of the Shie Hassaikai hideout. He is young, scared, vulnerable. Something in Endeavor sees that boy and thinks of missteps in his past, the mistakes he made with his own child. Is Izuku his chance for atonement? Or merely an encore?

    He brings the boy into his home, where sins of the past and sins of the present collide. Shouto isn't so sure about this waif sharing his table, and he suspects him of sharing his father's bed. That used to be Shouto's place, and he knows he should be horrified at Izuku's fate. Why does he instead feel envy? And the fact that Izuku asks after Overhaul, that he doesn't hate the man who hurt him... why does that fill Shouto with anger?

    OR everyone has bad coping mechanisms for trauma and a sick love triangle blossoms. Can you escape your past? Is it possible to unbecome what other people have made you?

    Summary

    "So what does your villain boyband do? What do you do there?"

    Dabi chokes.

    "First of all; it's not a boyband, it's not only made up of guys", Dabi got a hum as an answer, "and if you know I'm a villain, then why aren't you blowing my face off?"

    Katsuki stares at him.

    "You helped me, I'm not ungrateful", he looked at him with all the seriousness a fourteen year old could have, which was pretty cute. "And you are too lazy to get the whole world against you for things you don’t believe in”.

    He didn’t need to say it like that. Even if he was spot on. His heart crushed, his soul in shambles, his body shaking- A snicker took him out of his mind. Oh, he said that shit aloud.

    Summary

    Michiru Kagemori and Shirou Ogami tended to end up in a lot of trouble. It was what happened when one was a special task agent for the mayor. Not only that, but one of them was a human turned Beastman and the other was considered a god among his kind. So yeah, they were trouble magnets.

    Still, that did little to explain why they were suddenly consumed in a bright light while sitting on their couch.

    Read as Michiru and Shirou do their best to find a way back to there world, even if it means going to UA High and training to be heroes.

    Also, I just want to mention that I am posting this while there are less than 100 fics for BNA. Specifically, this is the 92nd BNA fanfic on here. At least of the ones that have it included in the fandom part. I feel special lol

    Summary

    They ran into Shinsou on their way out of the cafeteria. He greeted them, then eyed Bakugo.

    "Does Bakugo have a child slung over his shoulder?"

    "Unfortunately." Bakugo muttered.

    "Is that Midoriya?"

    Uraraka smiled at him weakly.
    "Yes. Look don't even ask."

    "He's been a pain in my fucking ass." Bakugo snarled.

    "Oh." Shinsou considered that.
    "Do you want me to brainwash him?"

    Summary

    Where before stood Shigaraki, now sat a small, black-haired child, blinking around curiously. The hands he previously had attached to himself were scattered all around him, the clothes significantly oversized.

    And next to him… In the same bartender outfit the mist guy was wearing… Stood a very confused Oboro.

    There also seemed to be a dead body near them, but Shouta didn’t pay it as much attention.

    He raised the villain who caused all of this mess by the front of his shirt. “What the fuck did you do?!”

    Summary

    Aizawa had been more than willing to help his student when Midoriya came to him asking for lessons in stealth. However, if he had known he'd have to try and escape a group of villains while his student was stuck as a middle schooler, he would have just said no.

    Summary

    "We will fight, not out of spite
    For someone must stand up for what's right
    Cause where there's a man who has no voice
    There ours shall go singing"
    -Hands, Jewel

    Previously, Aizawa received a call from All Might stating that Midoriya was hit by a quirk. As he arrives at the station, it seems like this might be a second chance.

    Summary

    “Ah, and I hate to do this to you, but there’s a couple questions we have to ask since you’re awake now. Is that all right?” Wondering why his input was needed for that, Touya nodded. Anything they wanted. Whatever he could do to be less of an embarrassment.

    “Okay then, tell me if you need a moment whenever,” the woman started, “your name.”

    “Todoroki.” Even if he wished it wasn’t (and everyone else probably did too). “Todoroki Touya.”

     

    (A bystander loses control, and Todoroki Touya opens his eyes to a brighter world than he left behind.)
