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.
