Interesting that these Visored are willing to pop on their masks right away, something none of the ones that rejoined the Gotei 13 have done. Well, excepting Mashiro anyway. This just reinforces my longtime belief that there were some kind of strings attached when they were re-recruited as captains. Sounds like something the Central 46 would do, anyway. Because "Hollow powers baaaad" or something.

It's cool to see Hitsugaya in that snazzy uniform of his again, but I'm not excited at all by his appearance. He does need some kind of chance to redeem himself I think, but eh. If anything, the manga has been hyping the hell out of the upgraded Byakuya (who to be honest, shouldn't have even made it this far, but I digress). Granted, the other captains aren't necessarily out of commission, and seeing how early into the battle this is, Hitsugaya will very likely have help.

As for Askin, well... I don't have any issues with his ability, but at this point Yoruichi is basically excluded from the people who can kill him. And considering her much anticipated Zanpakuto reveal (after the Nanao thing, I wonder if she even has one), well, you can pretty much kiss any chance of that goodbye. Unless she can arbitrarily bypass his ability somehow, but I'd rather that not be the case. The Arrancar will probably end up being the heroes here, I think. Considering Askin's "poison" theme, I have a feeling that the whole poisonous Hollow reiatsu thing will come up again.
