He lives with his three younger sisters in a house without parents and is unaware that they possess magical abilities. He may also have latent powers, though they remain undiscovered. A mysterious and attractive girl named Mamiya Ayumi appears and takes on the role of a maid in their household. Her objective is to transform Haruo into a man to lift a childhood curse placed on her. Meanwhile, Kurusou Yuri, the serious and disciplined class president, has long had feelings for Haruo and resents Ayumi.
