Episode Title:
The Hundred-Year Grudge! Hiyori's Revenge.
Episode Description:
Wonderweiss battles Mashiro, who takes the upper hand until her hollow mask breaks. Before Wonderwiess can finish her off, Kensei Muguruma steps in to save her and takes her place, soon releasing his bankai at Wonderweiss. Meanwhile, Hiyori explains to Aizen why the Vizards have a score to settle with him, due to their painful experiences they endured one hundred and one years ago. Although Hirako warns the others not to fall for Aizen's taunts, Hiyori gives in and rushes in for an attack at Aizen, only to be stabbed in the back by Gin, badly injuring her. Hirako catches Hiyori, who then apologizes for not being able to hold back. Hirako calls for Ichigo, realizing that Orihime can still heal her. Meanwhile, back in Hueco Mundo, Ichigo has gone to help Rukia, Chad and Renji. The three are still in a battle with Yammy, trying to come up with tricks to defeat him but are ultimately defeated.
