Yuki and Zero have their hands full trying to quell the Day Class's enthusiastic pursuit of the Night Class in anticipation of the upcoming dance. In the midst of it all, the Headmaster asks Yuki to show a new transfer student, Maria Kurenai, around the academy. Maria seems harmless, but what lies beneath her seemingly innocent exterior will turn their world upside down.

At prestigious Cross Academy, there are two sessions of classes, the Day Class and the Night Class. As the school's Disciplinary Committee, Yuki Cross and Zero Kiryu keep watch over the Day Class students, who are all infatuated with the beautiful, elite Night Class students. As Guardians, Yuki and Zero must also protect the secret of the Night Class, they are all vampires!
