Looks like Uryu's going to be the one to defeat Shutara.
Presumably they're going to reveal both A schrifts at the same time.
Just give Ukitake SOMETHING before he bites it, that's all I ask.
And if Aizen MUST show up, at least have him do more.
Additional note - The transformation being referenced here is Hollowfication, not Complete Hollowfication.
So yeah, this 100% means the mask of his Hollowfication is the same mask as H2. He would not adopt his H2 form in its entirety, his Hollowfication is only the mask.
