Protagonist

The main character of Moon has no official name, and instead is named by the player at the beginning of the game. He arrives in Moon World after being sucked into the game through his TV. In Moon World, his body is invisible, and the only way for him to be seen by others is to wear clothes given to him by Gramby. Because of this, he is sometimes referred to by fans as the "transparent boy" (透明の少年). He is mistaken by many for Gramby's grandson, who is rumored to have died in an accident shortly before the protagonist's arrival.

Love
By granting the wishes and learning the secrets of Love-De-Gard's residents, the protagonist can obtain Love. The events in which love can be achieved are dependent on specific factors such as time and day or by satisfying another condition beforehand. Love can also be earned by catching the souls of animal corpses left behind by the hero.

Once the protagonist earns a set amount of love and sleeps in a bed, he can increase his Love Level in his dreams through the Moon Queen, who extends his Action Limit and allows him to explore the world more freely.
