Description:

Cross Academy is an elite boarding school with two separate, isolated classes: the Day Class and the Night Class. On the surface, Yuuki Cross and Zero Kiryuu are prefects of the academy, and attempt to keep order between the students as classes rotate in the evenings. As the night class is full of utterly gorgeous elites, this can sometimes prove to be a bit difficult. It is completely necessary, however, as those "elites" are actually vampires. Yuuki and Zero act as guardians, protecting the secrets of the Night Class and the safety of the ignorant day class. As the adopted daughter of the academy's chairman, Yuuki takes her job with a serious and energetic attitude. It also allows her to interact with her secret crush and savior, the night class' dorm president, Kaname Kuran. Zero, on the other hand, has a deep-rooted hatred against vampires, and at times, does not hesitate to kill. Can vampires and humans co-exist, even in the strict setup of the Cross Academy? Only time will tell. [Written by MAL Rewrite]

Description:

There is a legend that tells of how the world was almost destroyed thousands of years ago by the vampire queen after she unleashed her latent powers. Despite their efforts, the humans were unable to defeat her, and thus resorted to sealing her away until the time came that they would be powerful enough to destroy the seal and kill her. However, the humans are not the only ones after the seal. Having cast aside his kingdom and betraying his own race and the dhampirs (half-vampires), the vampire king is persistantly searching, even to this day, for where his queen has been sealed away so he may break the seal and free her before the humans do. Fearing that once the king and queen are reunited, they shall continue to destroy the world together, the humans and dhampirs hunt the king, using any method possible. (Source: Anime Source)
