Himeno has just transferred to Hallelujah Academy...a school that just recently went co-ed. That means Himeno is all alone in a sea of men, some of whom are too eager about the fact that Himeno is a girl. But luckily for her, there's the Hallelujah Council. Membership in that council will guarantee her safety...but the council president, Gaou, is a stubborn misogynist who refuses to admit Himeno! What should she do to prove her worth?
