You play a generic hentai game male and his band of girls as they fight against an evil force of... tentacles and their minions. MobyGames has a bit more on the alleged "plot."
There's a wide variety of very bizarre enemies, and huge boards that can take forever to play. The game itself isn't too terribly challenging, provided you play the levels in the right order. You get a hentai scene and a new character whenever you complete one, and a small tentacle scene if any of your girls drops to zero HP. The battle system is a lot like the one for the Lakers Series.
