Bungou Stray Dogs

Atsushi Nakajima is thrown out of his orphanage after weeks of incidents involving a mysterious white tiger, leaving him hungry and alone in Yokohama. By a riverbank he saves Osamu Dazai from drowning and discovers that the eccentric man belongs to the Armed Detective Agency, a group that handles supernatural cases beyond the police. Dazai happens to be hunting the very same tiger. Their encounter reveals that the beast is not stalking Atsushi from outside at all, but is a supernatural ability living within him. His life is abruptly pulled into a world of gifted detectives, mafia members, and dangerous criminals, forcing Atsushi to control his power while learning that the tiger has made him valuable prey to people far more dangerous than he imagined.
