At the behest of Mori, the boss of the Port Mafia, a young Dazai and Chuuya launch their investigation into the rumors of the previous boss’s revival, as well as the mysterious “Arahabaki” that’s somehow involved. The two’s mission carries the utmost importance, for if the truth about Mori’s predecessor gets out, the streets of Yokohama will run red with blood. Randou, one of the Mafia’s subexecutives, is said to have witnessed the supposed god, but where will his information lead?

Dazai and Chuuya face Randou in a climactic showdown. Their opponent wields the former boss with his powerful skill, putting the two on the defensive. A final blow is struck, the past is revealed, and the Arahabaki incident draws to a close, but…to what end will the boys’ decisions lead them?

Unfortunately, the capricious investigator isn’t interested. He lays down a condition for his assistance-each member of the agency will give Akutagawa a test, and he’ll have to clear them all if he wants Ranpo’s help. Willing to do anything in his quest for vengeance, Akutagawa begins with Kenji Miyazawa’s challenge to…plant a rice paddy? The alternate world of Bungo Stray Dogs: Beast continues!
