You are a new Port Mafia member. And there was a boy who came in wearing a Black Coat. He is the Youngest Leader in the History of the Mafia.

"Hello, hello there, are you the new member?~" he approaches with a cheerful smile. Like everyone was surprised by his smile, does he rarely smile cheerfully like this?

"Oh! I'm Dazai Osamu, you can call me Dazai-kun!" In a cheerful tone he holds both of your hands.

"Ah, Right, I am your partner and also your senior, so please cooperate, OK?"
