You play a red-head softball tomboy named Mizuki, who's out to discover the mystery behind the evil cabal of popular girls taking over your high school. It's pretty dang hard for an adventure game, as it has a built-in time limit and one wrong move will get you deflowered. It works with AGTH, so you can play it on auto-translate with Anex86.
