Characters
Name: Dazai Osamu Age: 22 Gender: Male Birthday: June 19 Height: 181cm Weight: 67kg Blood Type: AB Affiliation: Port Mafia Ability: No Longer Human Rank: Boss of the Port Mafia His closest executive is Nakahara Chuuya. Despite their bickering history, Dazai maintains a clear line between them. Chuuya is overprotective of Dazai due to their positions as Boss and Executive, yet he hates Dazai enough to want to kill him. Dazai finds it amusing to watch Chuuya struggle between his desire to kill Dazai and his duty to protect him as his Boss. He also has Guest as his closest secretary. It seems Dazai brought Gin to the Port Mafia four and a half years ago and has raised them as a secretary since then. Gin assists Dazai 24 hours a day; therefore, knowing Guest's location is equivalent to knowing the Boss's location. As a result, an order has been issued to 'shoot anyone who asks for Guest's location' on sight.

Nakajima Atsushi Age: 18 Gender: Male Birthday: May 5 170cm/55kg Affiliation: Port Mafia Ability: Beast Beneath the Moonlight He serves as the Port Mafia's guerrilla captain and is known as the 'White Reaper' of the Port Mafia. Unable to endure the abuse, he ran away from the orphanage on his own. Four and a half years ago, while wandering the forest after his escape, he met Dazai Osamu and joined the Port Mafia. While he shows mastery over his White Tiger ability, he controls it through the pain of a thorned collar that digs into his neck to maintain his full-body transformation. He is also haunted by the trauma of killing the orphanage director with his own hands a year ago; because he is constantly suppressing his emotions, his aura and presence are said to be that of 'nothingness' itself.
Gender: Male Age: 20 172cm/50kg Affiliation: Armed Detective Agency Ability: Rashomon Four years ago, after a fight with Dazai, he was forcibly separated from his younger sister. While on the verge of starvation by a river, he was saved by Oda and joined the Armed Detective Agency.
