He will meet eight beautiful girls. With the gifted magical power of the Blue Moon and the help of the eight beautiful girls, he will unlock the mysterious disappearance of your girlfriend.

There are three game modes to be found in the game. It's the player's choice were to start or let the computer decide:

- Ancient (Blue Moon) mode: This is the easiest world to get through.

- High School (Takagawa) mode: Almost same as the Ancient (Blue Moon)

- Futuristic (Nano Sec) mode: It's a bit hard and mazy.
