Special Mission! Rescue Captain-Commander Yamamoto!

Byakuya observes Yamamoto sealed within a pyramid-shaped barrier that a ring of Zanpakutō Spirits works to maintain, and Muramasa hints that the captured commander is central to his larger design. Learning the location from Yoruichi, a rescue team of Ichigo, Kenpachi, Yachiru, Shunsui, and Ukitake enters the maze-like cave from two directions to reach him.

The guardians peel the party apart one by one. Yoruichi slips free of Haineko and Tobiume with Utsusemi, Shunsui faces the twin forms of Katen Kyōkotsu, Ukitake is drawn into the childish games of Sōgyo no Kotowari, and Kenpachi finally gets the fight he wanted against Tenken and Gonryōmaru. Ichigo, sent ahead, is ambushed and bound by Kazeshini but breaks loose in his Bankai and puts the spirit down with a Getsuga Tenshō. Reaching the barrier at last, he is scorched testing its flames yet steels himself to shatter it.

Byakuya finds Yamamoto sealed inside a barrier upheld by Zanpakutō Spirits. A rescue party enters the cave, where Yoruichi fights Haineko and Tobiume, Shunsui faces Katen Kyōkotsu, Ukitake battles Sōgyo no Kotowari, and Kenpachi confronts Tenken and Gonryōmaru. Ichigo defeats Kazeshini in his Bankai, reaches the barrier around Yamamoto, and prepares to destroy it.

An anime-only Zanpakutō Unknown Tales entry adapting no chapters. The picture-book short has Suì-Fēng gush over Yoruichi rescuing her while an exasperated Suzumebachi struggles to get a word in. Techniques include Yoruichi's Utsusemi, Ichigo's Tensa Zangetsu and Getsuga Tenshō, and the manifested Shikai of Tobiume, Katen Kyōkotsu, and Kazeshini.
