Ōishi later apologizes privately, revealing that Kira has a decoy and assigning Mori a secret mission to kill the real Kira if necessary. Devastated, Mori finds solace with Okame, a local bar owner. After the ronin avenges their master, Mori, believing their mission complete, plans to leave his samurai life for Okame.
