The series comes from the manga that began in 2012 in the Young Ace magazine from writer Kafka Asagiri and artist Harukawa35.
The TV series adaptation was produced by Bones with Takuya Igarashi directing based on the screenplay by Yoji Enokido.
With HBO Max already having the first three seasons of Bungo Stray Dogs streaming on its service as part of the Curated by Crunchyroll section, they’re now updating that a bit.
