It's now 8 on 6 instead of 8 on 1.
Yhwach appears and declares that Ichigo coming down from the heavens has left an opening in the defense around the Soul King's realm, and Yhwach plans to invade. Ichigo tries to go after Yhwach but he is impeded by the other Sternritters. However, Renji, Rukia, Byakuya, Ikakku, Hisagi and Yumichika appear to hold off the Sternritters so that Ichigo can chase Yhwach.
I was hoping Yhwach would do something more interesting. I guess something has to happen to allow the Yhwach to get to his goal. Now that this has happened though, it'd be interesting to see Yhwach invade the Soul King's realm and fight the Zero Division. It'd be also be interesting to see who or what the Soul King really is.
In the meantime though, we have a 6 vs 8 fight between the shinigamis and Sternritters. Renji, Rukia, and Byakuya have been powered-up by the Zero Division, but I don't see how Ikakku, Hisagi and Yumichika will be much help. Every shinigami not powered-up by the Zero Division, excluding Zaraki, seems to be a scrub compared to the Sternritters, so it might be a tough fight. Then again, Zaraki is nearby and might rejoin the fight after getting a little breather? Or maybe every shinigami with a name is going to get a power-up?
