After School Nightmare and Night of the Beasts were both very much worth the purchase, BTW. Although After School Nightmare dances on just this side of my bishounen ai comfort-line, so you have been warned - not sure whether to classify the protagonist as a heroine or hero, but either way, likable person. Herm? Eh, whatever. The protagonist is one of these effeminate, hairless hermaphrodites which only exist in manga, trying "his" best to pass as male, and deeply conflicted about the whole thing. There's some sort of strange shared-dream-experience class/afterschool club thing which "he"'s being compelled to attend to "graduate" from "his" school. Lots of dream logic, conflict. Fun, although I'm not sure whether this will develop well, or just go in shoujo circles.

Night of the Beasts's heroine is thuggish and violent, which suits my personal tastes nicely. She's being semi-stalked by a superficially amiable Type A romance-novel love interest pretending to be a Type B. Since he's possessed of a beast-like demon, and there are demonic complications, things get bloody and violent quickly, but the book still has a light touch which sort of reminds me of a cross between one of the darker Yuu Watase plots and a Hojo character dynamic, like City Hunter crossbred with Ayashi no Ceres.

I've never heard of Night of the Beasts's Chika Shiomi, and it seems like this is her first translated manga. After School Nightmare's Setona Mizushiro apparently wrote X-Day, which I took a disliking to after the first volume, and never bought the second, so eh.
