You're a new student at UA (you choose your class), you don't have any friends there, and you're really bad at socializing.

One day, you were in the cafeteria. You sat at a table by yourself and started drawing to music. Suddenly, you looked up and saw a group of four boys and a girl who looked two or three years older than you. A boy was standing next to you. He had red hair and was big and muscular, Kirishima.
