    Summary

    Katsuki’s lips twitched into a frown of disbelief, his jaw slightly ajar as he stared at you. A choked sound struggled to erupt from the back of his throat. “What,” he whispered, “the fuck?”
    The little girl puffed her cheeks, which were painted a slight rosy colour. “That’s a bad word, mister,” was all she said, before she glanced down at herself.

    Summary

    Endeavor stared down at the child sitting on the pavement in front of him. Two-tone eyes, one marred by a red scar covering half his face, stared up at him fearfully. After a long moment, the little arms reached up to him.
    "Dad?"

    Canon-divergent as of chapter 220. Shouto is hit by an age-regression quirk on the way home from receiving his hero license. With the media already hounding him after his fight, Endeavor decides to keep him hidden until it wears off, deciding to use the time to try and rectify the mistakes of the past. Of course, things could never be that simple, not when the Todoroki family is involved.

    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.)

    Summary

    You know this feeling, when you just wanted to go to the groceries store to get some goddamn milk and you almost caused a fucking car crash, because your newly claimed toddler accidentally hot-wired a damn traffic light, which you didn’t immediately notice, ‘cause the little shit went airborne out of his ass-expensive stroller with his ridiculously strong tentacle arms, latched onto said traffic light and electrocuted it, while you were maybe thinking about a certain redhead?
    No?
    Well. Bite me or listen to my fucking story.

    Summary

    Katsuki’s world first ends when he sees Deku get hit by a quirk, and thinks he’s dead.

    It ends in a slightly different way when he realizes Deku has been transformed into a four-year-old, and he has a chance to talk to Deku without years of bitterness twisting everything.

    The world ends for the third time when Deku returns to his own age, and Katsuki has to face just how far apart the years have pushed them, and exactly how much he hates it.

    Summary

    During a mission, Gang Orca and Endeavor get hit by a regression quirk. Mina and Hawks are left with no other choice than taking care of them until the effects vanish, even if they have absolutely no fucking clue about what to do.
    Set in a kinda AU/future where everything is the same, but Mina is a few years older and sort of dating Gang Orca.

    It started as an excuse to write piss content and then I got too much into the story.

    Summary

    From: Yamada-san [14:33]
    Hey, yagi-san!! Sorry to ask this of you but could you keep an eye on shouta for me?? He got hit by a quirk a few days ago on patrol and thinks the world is a lot bigger than he is.

    “Blanket?” Yagi offers.

    “Too warm,” Aizawa-kun replies.

    “How about nearby in case you get cold?” Yagi suggests. Aizawa-kun levels a rather impressive glare at him. Yagi holds his hands up, placatingly. “I’ll keep it with me, then,” he says.

    Unexpectedly, Aizawa-kun’s glare darkens. “No,” he says. “Can’t keep it.”

    Yagi balks. “No, no, I’m not keeping it forever, just until you want it.”

    Summary

    Kirishima and his friends, which they fondly dubbed themselves the BakuSquad, had been minding their own business, just hanging around the mall one afternoon after class had let out, when, suddenly, Bakugou had gotten into an argument with someone. It wasn’t too surprising, considering how hotheaded he was, but what was surprising was when he suddenly turned into a toddler.

    Summary

    Dabi wrinkles his nose and peers down at the squirming toddler in Hari’s arms. It pouts back at him, bottom lip jutting out over the top one. He’s got Chisaki’s stroppy look down to a tee and Dabi supposes he does have the same golden eyes, the same dark hair. Even the same spray of light brown freckles across his nose. But it can’t be, Chisaki Kai is a full grown adult. This kid looks about two or three years old.

    “That’s a kid.”

    Summary

    “I can take care of him.” Shouta blurted out. His brain caught up a little late. The rational part screamed that he didn’t know anything about children. Another equally loud, insistent voice reminded him that this was Hizashi, would he really feel safe leaving him with someone else?

    “That would probably be best.” Tsukauchi agreed. He handed Shouta some paperwork. “Fill these in and you’ll have custody of Mic until he returns back to normal.”

    Or: Hizashi is hit by an age regression quirk and at first glance seems like a model child Shouta would have no problems taking care of for a couple of days.

    Summary

    Izuku’s mouth opens. Somewhere behind him, Tenya tries to explain something to him.

    Kacchan got younger, that enough is visible. He has no idea what the hell happened but the Kacchan sitting in front of him is without a doubt the one who entered UA with him when they were 16.

    “K-Kacchan?” Izuku screeches.

    There’s an explosion and everything dissolves into pure chaos.

    Summary

    It’s safe to say that Aizawa Shouta is having a bad day so far.

    Kaminari and Mina had been given detentions for passing notes in class. Because Bakugou wouldn’t stop screaming at Midoriya for acing the test while Bakugou had only received a 99, Aizawa had to separate the two. Bakugou maintained a humiliating bow for half of the class during his apology, and that punishment had been hard to get Bakugou to do in the first place because of his damned pride.

    To put the cherry on top, the former Number one hero All Might is missing now and thus Aizawa has to fill in for the damned scarecrow of a man.

    -Where Toshinori is hit with a de-aging quirk and it's up to Aizawa to take care of him and along the way, learn things about the Symbol of Peace that he never thought were possible.-
