BEAST Chapter 18

Goodbye (さよなら,) is the 18th chapter of the Bungo Stray BEAST manga.

Summary
Dazai reveals that he and Oda were friends in the original world, but Oda nevertheless calls out the things he did towards Akutagawa in their current world. Dazai calls out to him by his nickname, but Oda demands him to stop addressing him as Odasaku, asserting that an enemy has no reason to call him as such. Overcome with shock, Dazai recounts his hardships fighting Mimic without Oda, taking over Mori, and expanding the Mafia's influence all for the sake of their current world.

With Oda unwavering in his gunpoint, Dazai confesses that he called Oda to the bar to impart his final goodbye, remarking that a life where one could say goodbye to someone is a good one, especially when it hurts to say such farewell to said someone. As Oda agrees to his claim, Dazai stands up and allows Oda to shoot him, albeit requesting to shoot him anywhere but in the bar, which Oda acknowledges. Dazai thanks him and bids goodbye to Oda.

Still falling from the building, Akutagawa notices that the tiger can even regenerate from its wounds. He then activates Rashōmon, but the tiger bites into his shoulder's flesh. Akutagawa estimates that the tiger's tough body and regeneration would allow Atsushi to survive if they crash to the ground, unlike him. Even if he uses Spatial Distortion, he surmises that his brain and internal organs would still not be able to handle the impact, similar to the result of dropping a sturdy box with a cake inside onto the floor.

He then ponders of stretching his cloth and hooking it to the wall before landing, but he soon rejects such idea, since discarding his only line of defense would allow the tiger to completely bite off his shoulder and kill him. He then concludes that the only possible outcome is death, helplessly bearing the thought of his sister as they continue to fall.
