Ep. 44: Ishida Ultimate Power!

44

Uryuu uses the Quincy technique ransoutengai to overcome the paralysis of Mayuri's zanpakutou. However, he is outclassed by Mayuri, and is forced to take off his sanrei glove, an act that releases the limits on his powers. Uryuu proceeds to completely overwhelm Mayuri, even after Mayuri releases his bankai, but Mayuri escapes by transforming into a liquid. Nemu gives Uryuu the antidote to the poison of Mayuri's bankai, and Uryuu continues on towards Rukia's cell, severely weakened, until he is confronted by another Soul Reaper captain, Kaname Tousen.
