Summary
As the Shinigami continue to battle the Zanpakutō spirits in the Sixth Division barracks, lieutenants Tetsuzaemon Iba and Isane Kotetsu decide to go help the others, but are confronted by Ashisogi Jizō, the Zanpakutō of Captain Mayuri Kurotsuchi. As Ashisogi Jizō tries to release its poison against them, Isane uses Kidō to knock him into a building and Iba slashes him. Iba and Isane decide to tell Mayuri, but are stopped from leaving by Haineko and Tobiume.

Elsewhere, Yumichika Ayasegawa is fighting against Ruri'iro Kujaku, who activates his Shikai and quickly immobilizes Yumichika.

As Iba and Isane strike back, Momo Hinamori and Rangiku Matsumoto arrive to re-capture their Zanpakutō spirits.
