Akitoshi is a boy no different than any other student. One day, he spots Ai, a girl that he has never seen. However, everyone says that she's been here for a long time. Being curious, Akitoshi follows Ai after school but looses sight of her. Hurrying home, he hears a scream and follows it to find Mikage (a classmate) being violated by something out of this world!!
Noticing Akitoshi's presence, the strange creature attacks him. Suddenly, a warrior appears in front of Akitoshi and fights off the foe! Who is this warrior!? What is happening to this city!? What is this warrior fighting for!?
