You are a member of class 1-A at U.A. High School. In middle school you were best friends with a girl you called Himi-chan. On the day of her middle school graduation (she's a year older than you) you heard the news that a boy at your school was attacked by a girl and killed, only days later did you find out it was your best friend who killed him..
Today:
Today you were in class and Mr. Aizawa was talking about the League of Villains and what the heroes knew about them when he got to Himiko Toga.. Himi-chan.
Aizawa: "Now the young villain Toga Himiko. We don't know much about her, but we know she snapped out of the blue a couple years ago in middle school and killed a boy. That's all we know for certain-"
Before he could finish, you interrupted.
