Ayumi Mamiya is a young witch who was cursed during her childhood. The only one who could lift this curse is Haruo Yoshikawa, which forces her to study at the same school and move into the Yoshikawa residence as the maid. Because of this, she and Maika constantly get into arguments usually involving Haruo. The only thing Ayumi focuses on is trying to make Haruo a man through flirting and sometimes spells. She uses her curse as an excuse for flirting with him..
