Hitsugaya and Matsumoto enter the Central 46 Chambers to find all of its occupants slain. Kira arrives, and Hitsugaya and Matsumoto pursue him. Hitsugaya returns when Kira tells him that Hinamori has entered the Central 46 Chambers. Ichimaru meets Hinamori and takes her further into the chambers, where she is reunited with Aizen. Aizen impales Hinamori with his sword, and Aizen and Ichimaru leave the chamber. Hitsugaya arrives, and is enraged at Hinamori's state. He uses his bankai, but Aizen effortlessly defeats him. Unohana appears, denouncing Aizen after discovering that he is a traitor. Aizen then informs her that every Soul Reaper has been under the hypnosis of his zanpakutou, with the exception of the blind Tousen, Aizen's other accomplice.
