Vanilla and Chocolat are two young witches who are sent in the humans world in order to decide who will become the new queen of their world. Their goal is succeeding in getting colored hearts from boys by being nice to them. When the boys fall in love with them, their feelings turn into a heart that the witches can take with a magic spell. The hearts are different colors for different feelings, such as surprise, love, or jealousy. Each heart can be used like money in their world, and some are worth more than others. Vanilla and Chocolat go to school like regular humans, and they take the hearts of the boys that they see at school and at other places in town. They can also get a heart that represents friendship from other girls, and they learn that it is important for the future Queen to be able to be nice to girls as well as boys. Also, Vanilla and Chocolat are friends, and they decide that they will stay friends no matter who becomes the queen of their world at the end of the competition.
