Bleach

The Man Who Takes Command of the 11th Division! (14x48)

:

The episode starts off with Ichigo sparring with Renji and after that a man from squad 11 named Seizo gives the two tea, but everyone seems to disrespect him and Ichigo wonders why. It is later revealed that Seizo was once a strong warrior, but because he lost almost all of his spiritual energy to a hollow he became weak and no one after that respected him. After regaining his confidence in his skills he defeats a group of hollows alongside Ikkaku. The episode ends with Seizo leaving the Thirteen Court Guard Squads with all of Squad 11 including Ikkaku bowing down to him in respect.
