This series showed so much promise in the beginning, I felt. In fact, I second Bill's statement: I'm biased towards Inori, so I still have a lingering hope that things are always darkest before the dawn. I mean, random people being able to enter a supposed metaphysical space, even when it should be impossible, isn't anything new. If we're still making comparisons to Code Geass, didn't Lelouch and Suzaku and Nunally and Karen and who knows who all else enter that alternate world? It's been a very long time since I've seen the series now, so I'm probably a little off, but the basic idea is still the same. That, of course, doesn't excuse GC... I'm just trying to make a point that it shouldn't be surprising.
However, the convenient rules regarding Voids is where I think the episode fell apart. All of a sudden, "with his power", he can extract a Void while the person is still conscious, and subsequently give that person their Void to use? I was prepared for the "still conscious" bit, since we talked about it before, but how and the hell is someone who doesn't have the "power of the king" (or whatever it was called in the beginning) using it? And it can draw out other Voids as well? So let me get this straight... he's been forcing Shu to draw Voids for his own goals, when all he really had to do was have his own drawn out, and then he could have done all the work! Or so it would seem...
I won't even go into the whole "marriage ceremony"... that was just pointless. And the random case of Amnesia to explain everything. I said I still have a lingering hope for this series, but it's a very, very thin hope.
All that aside, this episode did feel like a final episode, slightly. I'm guessing the continuation will focus on Shu leading Undertaker, or Funeral Parlour, or whatever the fuck they want to be called. That would be the obvious conclusion since Gai's jacket miraculously made it out with Shu.
At least we have the music to look forward to still.
Edit:
/facepalm... that's what I did.
