Bungo Stray Dogs: BEAST

In an alternate reality where destinies are inverted, the foundational loyalties of Yokohama's most formidable figures are completely reversed. Within this parallel universe, the ruthless Port Mafia enforcer Ryuunosuke Akutagawa finds himself walking a dramatically different path, driven not by the dark ambitions of the underworld, but by a desperate quest to rescue his younger sister from the clutches of the very organization he usually serves. This perilous mission sets him on an inevitable collision course with the Armed Detective Agency, thrusting him into a direct confrontation with the syndicate's most terrifying executioner. Standing in his way is the fearsome "White Reaper," an entity whose lethal reputation strikes dread into the hearts of all who cross him—none other than Atsushi Nakajima, now firmly aligned with the forces of darkness. As the boundaries between shadow and illumination blur in this compelling alternate tale, the stage is set for a fateful clash of opposing forces. This gripping narrative explores an inverted world where the traditional roles of light and dark are tested, forcing these two powerful adversaries to confront each other under entirely unprecedented circumstances.
