It all started when a minute before we began morning activities, something suddenly occurred. The floor started shining a dazzling light, the shining expanded in an instant, and 30 classmates, including me, were laying on top of a place we didn’t recognize.

The world is terrorized by the powerful Black Witch who has been sealed in the moon. Every ten years, the night of Hexennacht arrives and a chosen witch must battle the Black Witch in hopes of finally defeating her.

As the current decade’s Hexennacht approaches, a mysterious girl named Kagami Kagami arrives and meets Horinouchi Mitsuru, the daughter of the previous Hexennacht representative.
