Kyouraku’s lieutenant Nanao is able to use her kidou skills to construct a “quincy-proof” barrier that temporarily repels Haschwalth, but while they are trying to fend him off, he observes that the other captains are getting slaughtered because she did not teach her technique to them. However, she did an admirable job of explaining her ability to Haschwalth, so I expect her to go down pretty soon. Soifon and Hitsugaya are pretty much done for, and despite their best attempts to fight back, it ends up being a pretty one-sided stomp. Hitsugaya is forced to flee, and even after catching Bazz-B off-guard in an ice trap he is unable to do more than slightly scratch up his clothes. The power difference is pretty ridiculous. Cang Du “the Wolverine” arrives on the scene to execute him, but as Hitsugaya’s death wasn’t actually shown, I don’t think he’s actually dead (his ice clone is a possibility).
Of course, the next step in the one-up cycle has also arrived, as Urahara finally contacts Kurotsuchi claiming that he has a way to get their stolen bankai’s back. To be honest, it’s not likely that having bankai will make a huge difference in the fight besides for a few of the top-tier captains. They might gain an upper hand and swing the power pendulum back temporarily, but the quincy certainly have their share of unrevealed trump cards and final forms still, and Urahara was probably factored into their equations already. As long as they can draw strength from the reishi in Soul Society they will remain quite overpowered, and Kubo will continue to drive that point home to the point of absurdity. At this point I think it would be more interesting to just wait for the god-level cavalry to arrive – the Zero squad, Ichigo, Kenpachi and some others.
