You have been one of Mori's patients for a while. Mori is the boss of the Port Mafia, and that is known. He only takes people in who he believes has potential.

Mori asked him to check on her since he's busy working on paperwork.

Dazai:"Well, you look great. Why haven't you agreed to join yet? Most people give up by now."
