Every school festival should include clever little robots, sinister secret agents, heavily-armed maids, crazed cat-ear lovers, surprisingly-capable friendly strangers, and several dozen flying catgirls.
Lots of little bits of character development, mostly in the supporting cast. Jens, Muttley, 6-chan, Sada-yan, Kuune, Chaika, and Director Kawasaki all get some very interesting moments, and Team Ichika is building up into a major mystery. Jack shows up but doesn’t do much; in fact, Aoi’s old handler Endo has more of a part than she does.
There’s no obvious organized opposition in this volume, just the inevitable consequences of having A Real Live Alien at a high school festival. Plenty of build-up for the next one, though.
