Based on the manga series by Hiromitsu Takeda, this romantic comedy is about Takeru Ohyama, a typical perverted teenage boy. His new school doesn't require entrance exams, and it just turned co-ed! Unfortunately, his dreams of a happy high school life are dashed when he finds out the school is much more than it seems. All of the students wield a special item—a Maken—to unleash their magical abilities in duels! Can Takeru find a Maken that works for him? Even while trying to fit in at a new school and dealing with all kinds of girl problems?
