title: Showdown of Mutual Self, Ikkaku vs. Ikkaku!
Captain Kyōraku meets up with fellow Captain Ukitake, privately discussing how the incident involving Ichigo seems too planned out to be believable. Ukitake asks him what they should do next, to which he suggests that they go through the events from the start.
He recalls Captain-Commander Genryūsai Shigekuni Yamamoto informing the other captains during a meeting of the return of Captains Kenpachi Zaraki and Mayuri Kurotsuchi. The Captain-Commander asks Mayuri what occurred in the Dangai, to which he explains that the Substitute Shinigami, Ichigo Kurosaki, was directly responsible for their entrapment.
