Here's my favorite page from chapter 159:
This chapter was a weird one. It doesn't say what shocking thing Umi saw at the end of the last chapter (all we see of Umi is the first page with the caption, "Can Umi's power bring Excel back?"). Excel herself sleeps for nearly the entire chapter, while Elgala keeps pissing her off by waking her up.
The weirdest thing that happens, however, is that SOMETHING takes over Iwata's body. It refers to itself as "we" and before anyone asks, it doesn't talk like Il Palazzo, Ropponmatsu (either model), Tenmangu, or Miwa (except the Miwa of the past, I guess, but that's not really conclusive evidence). Though I suppose it makes a very... Tenmangu-y face in the last panel? That's just my opinion. But again, it doesn't talk like him at all. It has a polite but excessively cheerful demeanor... reminds me of Xellos, just a little.
This "we" doesn't tell Misaki much, but it DOES say this: "That thing your side calls the 'core'...
another 'core'--" And it cuts off there, but it uses a particle that means that "core" is an indirect object to the following verb. What that implies, basically, is that whatever the hell is possessing Iwata's body meant to say more than just "there IS another core" or even "We HAVE another core." It COULD be saying, "Another core is being used," or even "We made another core," but there's no way of telling.
Of course, right after cores are mentioned, the scene then cuts straight to Excel. Drop yourself down a pit if you're actually surprised at that one.
ETA: Pffhahaha... I just now glanced at the page I actually uploaded, and Kabapu is saying, "My desire to talk to you is mountainous... but first, THE BATHROOM."
