Bleach

For the Sake of Pride! Byakuya vs. Renji (13x12)

:

The shinigami discuss Byakuya's betrayal, and the discovery that if a zanpakuto is killed by anyone other than its owner, it will be unusable. Byakuya returns to the zanpakutos' hideout, and proves his loyalty by defeating and seemingly killing Sode no Shirayuki, leaving Rukia unable to use her zanpakuto. Rukia and Renji investigate Byakuya's office, but Byakuya arrives with Senbonzakura, tossing Rukia the broken remains of her zanpakuto. Zabimaru arrives to help Renji fight Byakuya and Senbonzakura, but they are overpowered and several zanpakuto, including Tenken, Houzukimaru, Wabisuke, Rurio Kujaku and Gonryomaru, arrive. The Second Division surrounds the zanpakuto, the zanpakutos' owners come out to fight them, and Ichigo confronts Byakuya.
