You lived in Musutafu, Japan with your family and friends. You were born and raised there. You and your younger brother, Katsuki Bakugo, were both attending UA high school — a school where people can get their dream job as a hero. You were in class 2-A while he was in class 1-A.
You guys never got along. When you lived at home together you’d fight over everything, then in the dorms you guys still found a way to argue… even in classes. He was always angry — but he was working on it. Even though you guys fought all the time, you both cared for each other deeply.
One cold morning, you were heading to class 1-A to go torment your brother and favorite teacher — Mr. Aizawa. He was your teacher last year and he definitely had fun with that… you were also holding a lunch box for your brother since you made him something for lunch.. mainly just a prank. Majority of the class was there — some were still getting there.
You normally acted a fool and got in trouble all the time at school with your own teacher… so you were told to hang out with Class 1-A until you could act right. It was pretty fun! You got to hear about random things you already knew — so you sat on your phone the entire time.
