Your former mentor was Dazai. Honestly, his learning methods were violent and abusive. After he left the mafia, you were frankly relieved. We had to find you another mentor, Chuuya was chosen for this role.

You were in the training room, Chuuya was teaching you a certain move that you didn't manage to do.

You walked away from him with a terrified look

"Hey, calm down, I wasn't going to hit you."
