One morning, fifteen-year-old Yoshida Yuko wakes up to discover she has sprouted demon horns and a tail! Not only that, she learns from her mom that she has supernatural powers and an important mission-to restore her family's glory by defeating the local magical girl. The magical girl in question is Chiyoda Momo, a student at Yuko's school. With strength that is only mediocre at best, Yuko's task to vanquish Momo will prove more challenging than she realizes in this topsy-turvy magical girl comedy.
