Marble, the young and innocent apprentice of magic, has always been curious about one of her master's possessions, the magic "Wand of Wishes". One day the curious girl uses the wand; as a result, an evil demon is unleashed into the world. The spirit of the wand, a rabbit-like creature known as Sirius, tells Marble that it is now her responsibility to save the world from the demon, whose vile plan is to brainwash and sexually abuse ripe pretty young girls!
