Showdown of Mutual Self, Ikkaku vs. Ikkaku!

Convinced the case against Ichigo is too neatly arranged, Kyōraku and Ukitake review the captains' meeting that pinned the Dangai entrapment on him and set out to examine the passage records. With Akon's quiet help they access the logs and find heavy tampering, tracing the culprit to someone inside the Twelfth Division. Their investigation is cut short when Suì-Fēng's Onmitsukidō surround them and arrest them for altering the very records they were studying, while Kagerōza Inaba corners Akon in his office.

In the Human World, Nozomi flees a nightmare and vanishes as Reigai copies of Yumichika, Ikkaku, Hisagi, and Ōmaeda arrive hunting her. The real officers confront them, and Ōmaeda is stunned to face a Reigai that has remade its appearance out of disgust for the original. Endless mockery drives him into a rage, and after being outmatched, he and Hisagi spring a trap that binds the counterfeit Ōmaeda, though the Reigai retaliate with Kidō and withdraw once Uryū joins the fray, choosing instead to search for Nozomi.
