Since ancient times, it has been believed that it harms people with its supernatural powers, but in this modern, civilized world, no one has ever seen it, because those who see it are unable to return to the real world. Chloe, an apprentice witch aiming to become a full-fledged witch, is working with Asmo (a hat), the source of magical power, to gather large amounts of it from men's semen. However, Asmo is a great demon who has been sealed away. He is plotting his resurrection, but Chloe is unaware of this. Asmo is using Chloe to achieve his own goals, lending her his powers.
