Following this battle, Renji goes to the site of Rukia's execution in a last attempt to save her despite his extensive injuries. Ichigo, having beaten him there, entrusts Rukia's safety to Renji and the two try to escape. Along the way they are met by Kaname Tōsen, who teleports them back to the execution site. Upon learning that Tōsen and Sōsuke Aizen are traitors that intend to kill Rukia, Renji fights to defend her, but is effortlessly defeated by Aizen. Rukia is ultimately saved by Byakuya, though Aizen is able to escape the Soul Society.
