Do you suspect that maybe Kuu's not entirely human at all?

Reflecting and analyzing the light coming from within Kuu, I suspect other thing. Either she's the fourth AA that Kyoshiro referenced about or the fourth AA is sleeping within her.

Spoiler for AA info:

The fourth AA is the blond chick. Also the owner of Megingjord.

And... they just updated the main Kyoshiro website. There's now some info about the next episode, which didn't really make any sense with the google translation. But there was a video!

Spoiler for episode 4:

From what I saw, it looks like Kyoshiro reveals some stuff to Kuu, though not sure what. He just had a serious expression while telling her something and she had complete shock etched on her face. That short clip of Kaon was really sad... Looks like Mika just dumped her in some room after the experiment.
