She first appears when she buys the Maho-do from Dela (who won it from Majorika in a card game). Her charms are very powerful but cause horrible side effects. When Doremi and the other girls beat her in a duel, she gives them Maho-do in return that they tell no one she was beaten by witch apprentices. She reappears later as a magic frog with an apprentice of her own, Onpu. (source: soaring_wings)
