User blog comment:Primeramizery/is it just me, or does everyone else have a feeling that there will be a rematch between uryu and mayuri?/@comment-5551986-20130907201646

I wouldn't really count on Mayrui defeating Askin. Namely so far, they can still steal bankai. Shinigami cannot really perform the "finishing blow" as easily against a Stern Ritter when they are using Blut Vene with just a shikai, not to mention Askin seems pretty powerful.

Besides, if every Captain in Soul Society defeated their retrospective opponents, who will the others such those in the Soul King's Palace, Hueco Mundo and the Human world fight. The Gotei's allies will just turn up to a finished war which doesn't make sense. I'm quite certain that until Urahara turns up with the Bankai stealing solution, things are looking bleak for the Gotei, especially so considering their manpower is vastly reduced after the last invasion, and there seem to be more enemies present this time as well.

Besides, if someone of Quilges level can use Volstandig, im pretty certain more higher ranked members can use it too in the case the Gotei get back or prevent the Bankai stealing.
