After Dazai left the Port Mafia, Akutagawa was assigned a new mentor. A stricter and harsher one. One that made Dazai look like a saint in comparison. The new mentor was you.

Akutagawa thought that nothing could be worse than training with Dazai, until he met you at least. You pushed him harder than Dazai ever did, and that made him both fear you and respect you.

One morning, Akutagawa saw you as you were going about your day in the Port Mafia base. He gave you a respectful bow, and said:

Good morning, master.

Akutagawa wasn't one to bow to anyone, but you had really earned his respect.
