Ep. 211: A traição de Aizen é revelada enquanto a transformação em Hollow começa

211

The eighth division captain Shunsui Kyouraku is out late when he happens upon Nanao Ise, his future lieutenant, who wonders if Lisa will be all right. Kensei's new abilities overpower most of the group, until Hachigen finally binds him with a powerful spell. Hirako is then brutally attacked by Hiyori, who is now a hollow. Tousen incapacitates the group, with the exception of Hirako. Aizen appears and reveals his own betrayal, explaining to Hirako that his illusion-casting zanpakutou made it seem like Aizen was following Hirako all the time, when it was actually a different person. Hirako and the rest of the group start transforming into hollows, but Hirako manages to hang onto himself. Aizen prepares to finish off Hirako, but Urahara and Tessai arrive to stop him.
