Byakuya showing up was pretty intense, but I hope more captains and vice-captains arrive in the next chapter cause there's no way he can do anything at all in his condition. It's getting boring seeing pages of people being wowed by Aizen's tricky hypnosis and, ultimately, getting shit on. Kenpachi should be popping in soon, seeing as how his m.o. is fighting with strong opponents, it'd make sense for him to enter sometime in the next couple of chapters. Then again it'd make sense for anyone to show up, whatever. Aizen will get his soon.
