Impressed by her abilities, the master names the young magician "Princess Tenko" in recognition as his successor as the next Tenko and the Master Guardian of the Tenko Box, a magical wardrobe that contains many magic gems known as the Starfire Gems. Two of the most senior students, the twins Jana and Jason watch on. Jana become jealous of the newcomer when she is chosen to become Tenko's successor and conspires for rebellion. Jason tries to talk some sense stating that unlike Jana who had slacked off during training, Mariko is more responsible and therefore Tenko could trust her. She convinces him to help her and succeed at stealing two of the Starfire Gems for their own use.
