For centuries, vampires and humans clashed in bloody conflicts. Chairman Kurosu wants to break this dark cycle, by opening an Academy where the futures of tomorrow can learn to coexist in peace. Cross Academy is thus split into Day Class and Night Class, and the two classes only meet during the changing of classes at dusk. Yuuki and Zero are the appointed school guardians, protecting the secret of the Night Class and maintaining harmony between the classes. But can vampires and humans really coexist in peace?
