Ukitake, Kyōraku, Renji and Unohana discuss Byakuya's betrayal, discovering that a zanpakutō will be unusable if killed by anyone other than its owner. Byakuya returns to the hideout of the zanpakutō and proves his loyalty by defeating and seemingly killing Sode no Shirayuki, leaving Rukia unable to use her zanpakutō. Rukia and Renji investigate Byakuya's office, but Byakuya arrives with Senbonzakura, tossing Rukia the broken remains of her zanpakutō. Zabimaru arrives to help Renji fight Byakuya and Senbonzakura, but they are overpowered. Tenken, Houzukimaru, Kazeshini, Ruri'iro Kujaku and Gonryomaru suddenly arrive. The second division surrounds the zanpakutō, and their owners come out to fight them.
