Ango

Works as an informant for the Port Mafia. He's currently also a spy for Mimic.

Antiques, memories, materialism

Working overtime, all-nighters, betrayal. Everything he is and embodies.

He is a tall man with short, dark hair that has the bangs cut so they regularly show his eyebrows, and lightly-colored eyes behind circular framed glasses (though his hair is portrayed as somewhat messier in the anime). His most notable feature is a mole above his lip on the left side of his face.

His normal attire consists of a pale brown double-breasted coat which is buttoned to the left, covering a tab collared shirt with a kobicha brown tie. His pants are the same color as his coat, with his shoes being roughly the same color as his tie.

For the most part, Ango is a composed, calm young man, showing more restraint than Osamu Dazai and more discipline than Oda Sakunosuke. Although he values both as genuine friends, he strongly believes that Dazai needs someone to keep him from acting out as much as he does.[3]

Despite being a spy for the Special Division for Unusual Powers, Ango takes his role as their informant seriously. This includes his efforts recording the lives of deceased mafiosi after the Dragon's Head Conflict incident. He records everything from their background to family lives, and makes sure all close relatives are aware of their deaths, but is careful not to let on their connections to Port Mafia. As such, Ango values life a great deal.
He holds a deep respect for both Oda and Dazai
