What the entire hell is that chair made out of??

Not only does Aizen destroy Yhwach's creepy chi chi babies, but he also offers to create a path straight to the palace. I'm starting to get the feeling that he's the true protagonist.

If the shinigami are going up, then they're probably going to run into Ichigo and co. (hopefully in the next chapter). If that does happen then we're gonna have a chapter full of sappy friendship speeches.
