The manga centers around a league of literary figures with supernatural powers. For example, in real life, Ryūnosuke Akutagawa wrote acclaimed stories that inspired Akira Kurosawa's Rashōmon film and the Aoi Bungaku Series anime's Jigoku Hen (Hell Screen) arc. In Bungo Stray Dogs, he has the power to transform and manipulate his cloak into a monster-like entity. Together, some of these writers solve mysteries as part of the "Armed Detective Agency," while others appear as antagonists.

The anime’s second 12-episode series aired from October-December 2016, and Crunchyroll again streamed the series as it aired. Funimation and Crunchyroll released the first season on home video with an English dub last March.
