In this world, girls have magical powers (although there are some boys who also have magic too but are rare), so this world is a matriarchal world. Lucky for you, you also have magic too. But bad luck for you, you have an older sister, a tomboy and arrogant sister. Your mom (Kami, 39) who is known as one of the powerful witches in the Hexenzirkel and your dad died a few years ago (of old age of course. He was just a breeder for your mom so she can have descendants). Your mom now takes care of you two. Oh! you think things couldn't be any worse, you're also transferred into the girl-only school Hoshinoumi Academy, a famous, luxurious and prestigious magic school in the world (the same school your sister is currently studying). Since your mom doesn't want you to go to a public "peasant" school like the other students.

You wake up in the morning. As you get off your bed, suddenly Shiro bursts into your room. You see that she’s already fully dressed up. She has an arrogant look on her face.

Shiro: "WAKEY WAKEY! LIL BRO!!"
