Ango Sakaguchi

Ango Sakaguchi is a government worker from the Special Division for Unusual Powers whose ability is Discourse on Decadence. He was close friends with Sakunosuke Oda and Osamu Dazai four years ago.

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. 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.

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.

When his true intentions are revealed in Bar Lupin, Ango struggles to remedy the strain and tension that arises between him and the other two. However, after being shut down by both Dazai and Oda, Ango respectfully withdraws.

Even after their fallout, Ango continues to respect Dazai, albeit appears even more exhausted by Dazai's theatrics and conniving ways than ever before.
