Fifteen Chapter 3

Phase.03 is the third chapter of the Bungo Stray Dogs: Dazai, Chūya, Age Fifteen manga.

Summary
Restrained by Port Mafia sub-executive Randō, Chūya is welcomed to the headquarters by Mori, thinking that the latter wants to discuss Arahabaki. As Dazai arrives, the two banter once again until Mori stops them, opening the subject of the previous black explosion. He also requests an apparently freezing Randō to deactivate his ability, which he agrees to despite initial reluctance.

After Randō leaves the office, Mori extends an invitation to Chūya in joining the Mafia, to which Chūya decimates his immediate vicinity in spite as a response. Specifically, Chūya cites the bloody horrors and paranoia that the Port Mafia has brought upon the city and denounces ever being part of the organization. Though Mori acknowledges Chūya's claim, he points out that such chaos was during the previous boss's era, who died of illness. However, Chūya asserts having heard the rumors that Mori killed his predecessor and demands to show him evidence that he did not to prove himself wrong, but Mori nonchalantly states that he did kill the previous boss.

Mori then retracts his first offer for Chūya and instead proposes that he work with the Mafia to mutually investigate Arahabaki. Should Chūya refuse, Mori states that he shall kill all of the Sheep; Chūya quickly lashes out at Mori, only to stop when Mori reveals having the Sheep cornered by the Mafia. Chūya then lowers his offensive guard, while Mori teaches Dazai about control and rational action as he has just witnessed. In the end, Chūya accepts his offer of a joint investigation, urging Mori to provide his intel first.

Accepting his deal, Mori states their objective to trace back where the previous boss was apparently found resurrected, particularly three times in Suribachi City with the fourth instance being witnessed by Chūya and Dazai the day before. Chūya argues that the dead do not come back to life; Mori responds by showing them footage of the previous boss inside the Mafia's impenetrable vault, much to the two adolescents' alarm.
