Second film that covers the second half of the series. It's a big step up from the first one, mostly because it can dive right into the action and forgo the introductions. The combination of moe/kawai stuff and experimental fantasy remains very peculiar, but it's nice to see this film tilt more towards the experimental side.
The plot continues where the first film left off. The relation between the aliens and humans is further explained and the film actually comes with some very interesting dilemmas, way more challenging than you'd expect from a film with chibi school girls. Then again, that's part of Shinbo's style.
The animation is pretty awesome. The mix of different visual styles and techniques is inspired and the battles with the witches are simply stunning. The rest isn't quite on the same level and some of the more timid scenes see a sharp drop in quality. Overall though, this is pretty unique. Looking forward to the final part in this trilogy now.
