Mikan

Mikan is a blonde apprentice level goddess under Willis Fujisaki that made her first appearance in Rance IV. Being an apprentice, her chances of success at leveling up Rance's party was originally nil, causing Rance to either lose all of his current experience, triple his current experience or power up his weapon. Since Rance was the first character to be evaluated for level up, he was the only member who was ever affected by her failures.
