Izuku and katsuki adopted you from an abusive home. They are both crazy psychopathic killers and once they found you and figured out you had age regression they immediately took you in and became obsessed with you
Bakugo was your body guard and has been for a month and he noticed that you have age regression and he wanted you to slip in front of him so he tries his best to become a caregiver and take care of you he wanted to be your papa and he loves you very deeply
Barbarian king bakugo was the ruler of his kingdom Izuku and Kris were his best friends they have known each other since they were baby’s literally. They know everything about each other but they start to notice little changes in you and suspect you have age regression and they desperately want to become your caregivers so they try to make you fully regress in front of them so they can take care of you and they know how they know all your favorite things on how to make you break but only in the good way.
You are the only one with age regrets and class 1-A takes care of you including the teachers and they never judge you and they think you are the cutest
Katsuki has been living in the country side all his life and is basically a cowboy. Then you move into the house next to him. The same age as him but your living there by yourself and you have been living in the countryside too but you moved here and bakugo knew you lived in the countryside too side before because of the clothes you were wearing and the Texas accent you had but he also noticed the scars that weren’t the kind you would get from working but much worse.
You were the only age regresser in class 1-A but they didn’t hate you or judge you for it. In fact they took care of you and became mamas papas and caregivers
This world is ruled by people with strong quirks were killing anyone is legal, the buildings are messed up the streets are filthy and everything else is messed up. But there is a sanctuary at UA for childeren who need a family. The whole class 1-A are considered brothers and sisters and Aizawa is the dad and hizashi is the mom. Soon they find you a 14 year old girl dirty, banged up, just wondering the streets all of them have had some pretty bad lives but you definitely had it worse. They found out your name and age and you where only a year younger then all of them and they decided you were going to be the cinnamon roll/ little sister of the class. They all pitch in to take care of you and teach you how to have a normal life. You sometimes still do your bad habits without realizing it but they are always there to help you. Izuku bakugo and kirishima help out the most and cherish you a lot…everyone pretty much adores you.
Izuku and katsuki both worked as therapists a a suicidal psych ward. When you came along you were supposed to stay for…3 years…yup 3 years and after those three years you were supposed to be put in foster care due to the parents giving you up. Her name was failure boy…yes that was her real name and she was angry and violent on the first day she almost killed another patient by choking them out. She had a lot of scars and marks all over her body but Izuku and katsuki vowed to not give up on you and they had therapy sessions with you that lasted a bit longer than everyone else but you were more angry and violent than they thought. You got mad at almost every little thing that went wrong and just seemed closed off. Anytime FB gets angry Izuku is gentle at first but if she gets dangerously violent when angry katsuki is more firm and she backs down but they don’t like it because after every time they are firm FB closes herself off more and they have to end the session early because she won’t talk anymore but no matter what they won’t give up
All of class 1-A is grown up now as pro hero’s and all living together in the same apartment complex. But something completely different happens. A little girl probably 7 years old moves in next door to Izuku and lives by herself. They all get concerned but they don’t want to make her feel uncomfortable so they decide to just be her friends and take care of her instead. They adopt her into this found family that they have. And they teach her how to be a real kid
Bakugo is now a pro hero with his own agency and soon he heard about you. A angry and violent kid about 15 years old who had immortality and blood manipulation quirk. He also heard you were a masochist who loved pain so he made you his own personal sidekick and he plans to mentor and raise you differently from the rest of his sidekicks. He never blames you for being angry and violent
Izuku and katsuki have been your friends since yall were baby’s but they started noticing changes. Changes that they were looking for, they were caregivers for age regressers at heart and wanted to be a papa/ caregiver so bad so he instantly noticed you were an age regresser and wanted you to trust him enough so you can slip infront of them so they can take care of you
It’s a new day and you bakugo kirishima and Izuku. You guys are all siblings but you are the only one who is adopted and has had the worse. They all used to be abused by there parents but after you were adopted you got the worse of it so after there mother killed herself you three went to love out on your own your the adored baby sister and is much younger than them, they are all protective, clingy, and very lovey, they are all really playful and loving and you guys do everything together, with you guys bakugo is more soft and playful, Izuku is more clingy and loving and kirishima is basically the oldest bother and loves you all to death no matter what kind of arguments yall have.
Class 1-A is a family. A really big family that shows love in their own ways and in mostly physical affection. When you arrived at the school you were hard to understand and very odd and seemed confused and mostly very violent. But the whole class grew on you and ended up adoring you. You were the baby of class 1-A you were also all the teachers favorite student even with your violent habits.
Bakugo Izuku and kirishima are now all grown up and pro hero’s and work with other pros and you, you are the youngest and mostly deadly hero in the hero community
Katsuki bakugo the leader of the most feared mafia group in Japan is…A dad… that right one day bakugo killed his number two enemy and found a little girl in the basement who was abused and tortured in brutal ways but once he found her he didn’t kill her he just adopted her and took her in ever since then he has become whipped and a big softie for his daughter he adores her
