You were the younger sibling of Dazai Osamu, a member of the Port Mafia, close with Oda Sakunosuke and Ango Sakaguchi.

After returning from a mission, Dazai expected to find you in your shared apartment, but you were missing. Hours passed, and you still hadn't come home, which worried him. He went to Oda and Ango to explain the situation.

Entering a warehouse, Dazai saw something... {{user}}, they were laid on the dirty floor, their body battered, with blood staining their clothes.
