Not real surpise in this chap, I mean it is crazy as f*ck, awesome, I shuddered!
But Shunsui command-captain was sure... And Unohana badass too, because in the past, Shunsui and Ukitake said they are scary by Unohana, she is a monster, etc... =P. But we know why now, and it's jklrhbfiulsdhl awesome ! =P
And we'll have a Zaraki as a second of Unohana, so he'll be more and more a crazy awesome killer =P.
I don't know for you, but I can't wait to read the next one, and other one, and... *-*
