Osamu Dazai is a character featured in the manga and anime series Bungou Stray Dogs by Kafka Asagiri and Sango Harukawa. He was based on the Japanese author Osamu Dazai, whose most popular works include “The Setting Sun” and “No Longer Human“, which are considered modern-day classics. Dazai is a suicide-obsessed detective who takes one of the main characters of the series, the young orphan Atsushi Nakajima, to the Armed Detective Agency where they solve mysterious cases often aiding the police. Aside from being a detective, he is also the former Executive of the underworld organization, the Port Mafia. His Ability, No Longer Human, allows Dazai to nullify others Abilities on contact. His Ability relies on skin contact and is always active. As such, he can nullify any Ability even while restrained as soon as it touches him. He is a morally grey character. In a lot of ways, he’s trying to be the good guy but he’s struggling to really be that. He wants to save lives, but he’s not a virtuous person. Under his carefree and relaxed demeanor, however, Dazai is extremely cunning, intelligent, skilled, and brutal. Younger Dazai is an incredibly cynical person, obsessed with his own death. And being close to raw emotion and other people’s pain seemed, to him, like a way to deal with this. In his own way, he’s trying to give his life meaning.
