Chuuya Nakahara from Bungo Stray Dogs
Chuuya Nakahara (voiced in Japanese by Kishō Taniyama and in English by Nicolas Roye) is one of the top executives in the Port Mafia in the anime/manga Bungo Stray Dogs.
Chuuya is Dazai‘s former partner in the Double Black team from when they were both part of the Port Mafia, and still works with him when their organizations work in tandem against a larger power. His main ability is gravity manipulation, but he also has larger god-like powers that can be overwhelming and only tamable by Dazai.
He has very pretty blue eyes and long orange fluffy hair, worn longer over one shoulder. He wears a white button up shirt, a black harness-type tie over top, a black choker collar, a grey vest, a black and brown bolero jacket, a black and brown longcoat that he wears off-shoulder, black pants, black shoes, and a pair of black gloves, all of it topped off with a black hat with a brown trim.
Osamu Dazai from Bungo Stray Dogs
Osamu Dazai (voiced in Japanese by Mamoru Miyano and in English by Kaiji Tang) is one of the main characters in the anime/manga Bungo Stray Dogs.
Dazai used to be a member of the Port Mafia, partnered with Chuuya, until he defected and went to join the Armed Detective Agency, the opposing organization. He has the ability to nullify other’s powers, and this has been largely beneficial with keeping Chuuya’s god powers in check.
He has fluffy brown hair and similarly colored eyes. The outfit we usually see Dazai in is semi-formal, he wears a blueish-white button up shirt, a bolo tie, a blue undervest, a black vest over top, cream pants, brown shoes, a tan longcoat, and is wrapped in white bandages all over his torso and arms.
Ryunosuke Akutagawa from Bungo Stray Dogs
Akutagawa (voiced in Japanese by Kenshō Ono and in English by Brian Beacock) is one of the semi-antagonists turned reluctant part time good guy in the anime/manga Bungo Stray Dogs.
Raised to fend for himself and his sister Gin on the streets, Akutagawa grew up with a great distrust for people, but also the need to be seen as worthwhile in the eyes of people he looked to for advice. The downside is this person was Dazai, so it left him with a rather large complex for constant approval after a while.
While mainly a part of the Port Mafia, through Dazai’s connections and in response to a larger growing threat concerning both them and the Armed Detective Agency, Akutagawa has been assigned to work with Atsushi under the title of Shin Soukoku (New Double Black). Neither of them are very happy with this, but they’re figuring it out.
Much like Atsushi, Akutagawa has rough, choppy hair, though his is pure black with white tips at the ends of the front bits. His eyes are a cool grey.
The outfit that he has is a bit special in terms of composition. While the base layer is a simple fancy ruffled shirt, black pants, and black shoes, the high collar black jacket he wears overtop acts as a conduit for his ability, Rashoumon. While it is not bound to that coat in particular, it is the one we generally see him use it with.
Atsushi Nakajima from Bungo Stray Dogs
Atsushi (voiced in Japanese by Yūto Uemura and in English by Max Mittelman) is the main character of the anime/manga series Bungo Stray Dogs.
Coming from a difficult and painful past in an orphanage, Atsushi is now a member of the Armed Detective Agency, able to use the power that he used to fear, when he was unaware of it. He is able to fully form-shift into a white tiger, which comes with superhuman healing, as well as the ability to semi-morph parts of his body, such as his limbs into clawed tiger paws while attacking.
He is one half of the Shin Soukoku (New Double Black) duo, assigned as such by Dazai, and works (reluctantly on both parts) in tandem with Akutagawa.
When he arrived from the orphanage, Atsushi was practically in rags, so the agency cobbled together an outfit for him. It consists of a white button up shirt, black mid-length pants, loose boots, and black suspenders, a tie, a belt with an extra long end to mimic a tail, and fingerless gloves. He has choppy greyish blonde hair with an occasionally visible black streak along the longer side, and purple-gold eyes.
