AsoIku book 11: WTF?

I have no idea what’s going on in book 11. That is, I understand the individual scenes, but have absolutely no idea where the story is going.

The latest bafflement is Jack showing up at Kio’s door and introducing herself (apparently for the first time) as a new neighbor, wearing her trademark barely-there cowgirl outfit and giving a completely different name that nonetheless has the initials JACK. This is minor compared to the literal catfight between two previously-unmentioned culture professors on a Catian space station, over who gets to go to Earth as part of the exchange program. And then there’s the teenage goth-loli MI6 agent who collects assistoroid plushies and just moved into the house formerly occupied by 6-chan’s friend Mahiro.

All of which seem positively normal when compared to Kuune holding a reception on board the ship (currently parked offshore from the new embassy) for a collection of Earth’s kami.
