In the small Nijiirochō in the Pacific Ocean, a crystal seal was scattered. Without this crystal, a devil would be revived and destroy the world. Smashed into seven crystals, they somehow ended up with seven girls living in Nijiirochō. In order to reclaim the power of the crystal, the girls and "heart ties" are needed. The devil will be completely revived in six months. To save the world from ruin, a "player" that lives in Nijiirochō was chosen by Pixy for the task.
