Kenpachi Zaraki vs. Retsu Unohana

Kenpachi Zaraki vs. Retsu Unohana is a fight during the Quincy Blood War between the Eleventh Division Captain Kenpachi Zaraki and the Fourth Division Captain, Retsu Unohana.

Prologue
After announcing his decision to the Central 46 of wanting to have two vice-captains, Shunsui Kyōraku goes on to reveal his intention of having Retsu Unohana teach the Eleventh Division's Captain, Kenpachi Zaraki, how to fight. Giving them permission to use the prison's lowest level, Muken as a stage for their training, the two captains descend and find themselves in an infinitely wide, featureless floor. Exchanging words, both former and current Kenpachi draw their weapons in preparation before lunging at one another.
