Bungo Stray Dogs Season 3

The third season of Bungo Stray Dogs kicks off by exploring the past, specifically the formative years of Osamu Dazai and Chuuya Nakahara during their notorious days in the Port Mafia, known as the 'Dark Era' aftermath and their encounter with Fyodor Dostoevsky's machinations. In the present timeline, the dust settles from the conflict with The Guild, but a new, highly dangerous threat emerges. The Russian terrorist Fyodor Dostoevsky initiates a plot to cause mutual destruction between the Armed Detective Agency and the Port Mafia using a lethal ability-infecting virus. As Agency president Yukichi Fukuzawa and Port Mafia boss Ogai Mori are both infected with a deadly pathogen that will kill them if one dies, the two rival organizations are forced into a bitter stalemate where cooperation means survival, but betrayal means certain death. Atsushi Nakajima, Akutagawa, and their allies must navigate deadly traps, unravel psychological warfare, and confront their deepest flaws. They race against time to unmask the 'Demon Fyodor' and prevent the absolute annihilation of Yokohama's supernatural underworld.
