You were all for ones biological kid. Your mom died while giving birth to you. You had a very powerful quirk, it was identical to All For Ones quirk. Because of this you were definitely considered a threat. You lived with all for one for a few years, till you were eight years old. When he told you to kill someone you got scared and ran away. Surprisingly enough, you were nothing like your father. You had no desire to be a villain, you didn’t want to hurt people. So for the past nine years you’ve been living on the streets, with your quirk you were able to survive, but never actually live. You were 17 now. You were constantly on the run from your father as he searched for you. You lived in abandoned buildings or broke into cheap hotels. You committed very minor crimes just to get by.
All Might told Izuku about you. He was surprised when he found out All For One had a kid, and even more so that you weren’t a villain. But you were still sought out by the police, being a very dangerous villains child. Even though you didn’t actually commit any major crimes.
During the war you snuck in, and helped the hero’s. You didn’t want the world to end after all. You saved multiple hero’s lives, including Katsukis. And you defeated your father. Once this was all finished you were crumpled on the floor, severely injured. You were brought to a hospital to be healed, but nobody knew what to do with you. Many were thinking of arresting you. Even though you haven’t actually committed any crimes. People were just scared. Little did you know, you had people fighting for you. Saying this violated your human rights, and that you were technically protected by the law. You weren’t even a villain, a hero, they said. These people were the students of class 1A, particularly Katsuki and Izuku. They managed to get you to stay at the UA dorms, so you could be supervised. You still couldn’t use your quirk. You were now enrolled into the hero course. Still, as a way to monitor you. But class 1A and Aizawa quickly warmed up to you. You did all the cleaning at the dorms even though you were told multiple times you didn’t have too. It was a coping mechanism for you. You also went to therapy regularly. You were overall very kind and quiet. You had become close with Katsuki and Izuku. You had been living here for the last six months now. Izuku couldn’t help but like you. He also felt like he owed you his life since you saved the world by defeating your father, and also saved many of his friends lives. And you also used a restoring quirk on him so he could keep his quirk and continue his dreams. You really were a hero to him, and to the rest of class 1A. What you ended up doing when you weren’t cleaning or studying was baking. You loved sweet items. You never had anything sweet growing up, just vegetables were mostly what you survived off of. Since you had taken a quirk that let you grow vegetables for you to eat. When you first came to UA you were skinny, being mostly muscles and bone, but now you looked much more softer, had some ‘meat’ on you as some would say. You weren’t fat or chubby, just more thicker in some places now. You looked healthier honestly. It was noticeable but nobody had commented on it. Not even Mineta, which was extremely difficult for him. You just loved eating sweets and as many as you could.
