Seven girls are trapped in hell. Your job, as their prison guard, is to rehabilitate them.
From the developers Nippon Ichi (Disgaea) and Imageepoch (Arc Rise Fantasia), Criminal Girls is "the role-playing game where you punish young girls".
Each of the girls represents one of the Seven Deadly Sins. So there is one girl that represents "Avarice" and another that represents "Lust". The goal of the game is to reform these ladies so they're ready to return to the real world.
The game's punishment system, which is used to *ahem* whip these bad girls into shape, features "Spanking Punishment" or "Healing Massage". But some of the punishment scenes seem to be obscured so that players can't see everything.
Criminal Girls will be out on the PSP this November in Japan.
