Shunsui continues to prove he is perhaps the single most awesome character in this comic.

Weighed down by the death of his mentor and the sheer responsibility he carries, but still standing and carrying on, because it's what has to be done? Check.
Having a plan for organization and how to keep the Gotei functioning and alive? Check.
Standing up to the useless wastes of flesh and air that are the Central 46? Check.
Rocking an Eyepatch of Power so hard it should send shivers up your spine? Freaking Check.

I hope the Old Man stays dead because Shunsui's 10x more awesome now, and the Gotei may yet end up a better place with him in charge.

Unohana's name is also Yachiru? Interesting.
She was a Kenpachi? More interesting.
She's the only one ZP respects and will listen to? Not surprising.
