Although I thought you had to kill the previous captain to become captain. Unohana is clearly not dead so you think they might have faked her death or something so they could move her into a less violent division where she wouldn't want to continue being all criminal kenpachi.
It's weird though. I'm okay with accepting the fact that she used to be a dangerous criminal and what not even given that we've never actually seen her in battle or remotely angry...I mean this is the same woman who politely asked Rubone and his crew to leave so she could heal Chad AND an arrancar. Yet somehow I have no problem swallowing the fact that she used to be a violent kenpachi lady.
Now I'm kind of hoping that take the focus away from Ichigo and Renji and kind of keep things going with Unohana and Zaraki.
