Bleach Volume 13

After defeating Chad, deeming him not a bad person, Kyōraku decides to have him incarcerated. In his fight against Kenpachi, though terrified of his opponent's overwhelming power, Ichigo finds the resolve to face him. But Kenpachi reveals he has not mastered his zanpakutō and he easily defeats Ichigo. At that time, Ichigo is brought into his inner world by Zangetsu to face another opponent: A hollow personification of Ichigo's that manifested from his training under Urahara. As Ichigo realizes that he knows nothing about Zangetsu and promises to learn more about him, the fight is stopped and Ichigo returns to fight Kenpachi again. This time, he is able to use all the power from Zangetsu, and as a result Ichigo is able to successfully battle Kenpachi to a draw. Kenpachi's lieutenant Yachiru Kusajishi takes him to another place and Kenpachi confesses that he lost because he has never been able to truly know his zanpakutō. Meanwhile, Ganju and Hanatarō find Rukia. But Ganju becomes infuriated when recognizes Rukia as the Soul Reaper who killed his brother Kaien Shiba.
