Our main character is a highschool boy who one day gets involved in a battle between a "magical girl" and a "cyborg-like" girl, and loses his life protecting a third girl, who he doesn't know also has magic powers. After the girl revives him, he starts attending his new school, which is also a place where children with magical powers gather, and he gets involved in a fight between the "magical girl" and the third girl, who uses a ring blade and can shoot beams of light with it. In the meantime, he also remembers at once that he can use a cursed sword, the memories having been sealed from him...
Unfortunately, the character's aren't very charming and the story isn't too engaging, or there's just too much going on at any given time.
