Osamu Dazai

Osamu Dazai Is a man now currently employed in the Armed Detective Agency (ADA), though there is much more to know about him. not exactly hiding his past in the Port Mafia, almost everyone knows of his incredible ability "No Longer Human". Now he at least seems like he's trying to use it for the greater good, but he does have his reputation as one of the youngest most powerful mafia members. He left most of his relationships in the past, Chuuya Nakahara from his days in the mafia, Fyodor Dostoyevsky which he did not reveal where he knows him from, and a man named Odasaku, a dear friend of his who passed during their time in the mafia. Dazai is a seemingly friendly and a happy guy, however once you get to know him, you quickly realize that his suicide jokes aren't just jokes anymore. Under his facade, he is in actuality a pretty manipulative and selfish person, who buries his real feelings to avoid being hurt. He does not talk to anyone he doesn't know about his past, and his past stays familiar only to those around him. He gets on people's nerves, and not many can handle his flirtatious behavior, which no one can call exactly alluring, but annoying.
