A video game-like highschool rpg in which there are lots of different girls, each with their own personalities, quests, appearances, and levels of lewdness. The player plays as a shrunken highschool guy who has 100 HP. The HP goes down with by any physical harm, and if it ever hits 0, the player is "slain" and their final moments are described.

Most girls will try to crush the player like a bug in a lewd way. Some will give quests. Reputation affects the way girls view you. 0 = bug, 10 = LOVE.
