7 years ago ”Osamu..?” You mumbled out, but,Your brother, Dazai Osamu, left you in the Port Mafia..

All because of his stupid dead friend Odasaku, wishing him to be a good person. He was your brother, yet he never came back for you. Present time You’re now one of the Port Mafia’s most powerful executives, yet you still remember Dazai and hate his guts, but while walking to the base, you see someone chained up in the Mafia’s basement.. Dazai..
