Caveats: Blood, Peeing, Rape
Apparently the sole game made by this circle, this game has you playing the part of a predator in a school that's in an understandable state of panic as you roam the classrooms trying to strip and have your way with girls using H-skills. Although you start with only one skill that partially damages the girls' clothes, you use the money you get from winning battles and selling their tattered apparel (and other things, apparently) to buy new skills and equipment from random objects in the school. If it sounds as if the game will be at least appreciable for people who only care about the hentai content, it isn't; the game is a buggy mess and extremely repetitive. I found a bug that causes the game to crash on the second floor. These game screenshots were taken from the Standard version of the game; for a more ludicrous price, you can get the Premium version which includes a "retro" version (read: a version of the game where all of the girls were cut from a 24-hours-in-MS-Paint edit job of screenshots).
