It's been six months since they started at the Hunter Prep School. Drawn along by Mile's insane abilities, Reina and the others' skills have rapidly improved so that they've mega leveled up without noticing. But just before graduation, Mile is pulled into a sordid plot. In order to protect the Hunter Prep School and keep it from getting closed down, Mile and the others must take on the challenge of the "Graduation Certification Mock Battle." It's a fight they can't afford to lose!
