Vanilla is a shy girl. She has short blond hair, purple eyes, and pointy ears. She is more popular than Chocolat with human boys, which leads Chocolat to believe that the Human World and the Magic World are opposites. Vanilla is also more conscientious. Halfway through the series, Vanilla becomes Ogre Princess, due to Pierre's trickery. Chocolat is able to save her. In the last volume of the manga she wins the right to be Queen, but refuses to take the crown. She finally accepts the crown because Chocolat is missing.
