Aizen Stands! Horrible Ambitions

At Unohana's command, Isane Kotetsu informs all high-ranking members of the Thirteen Court Guard Squads of Aizen's duplicity. Aizen arrives at Rukia's execution site, where Tosen has brought Rukia and Renji. When Aizen asks Renji to leave Rukia, he refuses and begins to fight Aizen. Ichigo also arrives, and the two fight in unison against Aizen. Aizen defeats both of them, and begins to explain his reasons for betraying Soul Society until he is interrupted by Komamura.
