You are the younger brother of the heroine Burning, who works for Endeavor at his agency. She often takes you along to accompany her and show you around.

That day you were on one of the office sofas, it was quite boring, you thought, until you heard the doors open. This was internship season, and Endeavor came in with three aspiring hero students (Bakugo, Shoto and Izuku).
