Season 1

Haruo Yoshikawa is an ordinary high-school student who lives with his three sisters, Maika, Chiaki, and Fuyuno. Or at least he was, until a new "bewitching" female student named Ayumi Mamiya transferred to his school and is now living at his house and working as a maid! To make things more interesting, not only is Ayumi really a witch, but Haruo's sisters are too! Moreover, Ayumi needs Haruo because he is the only one who can lift a curse off of her so that she doesn't lose all of her magical powers. The only way for that to happen is to turn him into a real man.

Ayumi creates a dream world inside Haruo's mind in which anyone who enters the dream world will experience their ideal dream first-hand. She hopes that this will turn Haruo into her ideal man, but alas, it failed. Later, Ayumi, Yuri, Chiaki, and Fuyuno use Time Highway Magic to travel back in time to find out exactly why Maika loves her brother Haruo so much.

Marin Nijihara, one of the few Witch Hunters left in the world, has come to bring divine justice upon the witch Ayumi, but it won't be easy since Ayumi's so powerful and Marin's a ditz. So Marin is determined to attack Ayumi's weakpoints, which involves pestering her around school until Ayumi can't take it anymore. Eventually, Ayumi takes on Marin in a final magical showdown... until Haruo shows up. Afterwards, Ayumi, Yuri, Maika, and Marin (who now has a crush on Haruo, thinking that he is a saint who keeps Ayumi's magic powers at bay) all prepare boxed lunches for Haruo to eat, but each girl suspects that the others have put in something weird in their lunches. So, they decide to have a taste test to make sure there's nothing wrong in them.
