Vampire Knight is a shoujo series created by Hino Matsuri, whose past works include Toraware no Minoue, Merupuri, and Wanted. Hino-sensei describes her newest series as a tragic love story, and it is indeed her darkest series yet, though it has her trademark crack!comedy and romance as well. Vampire Knight made its debut in January 2005 in the monthly Lala magazine, and is currently ongoing.
For centuries, vampires and humans clashed in bloody conflicts. Chairman Cross 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 only meet during the changing of classes at dusk. Yuki and Zero are the appointed school prefects, protecting the secret of the Night Class and maintaining harmony between the classes. But there is another secret lurking... There lies a legend that humans turn into vampires after being bit by one... How will Yuki cope when she learns that Zero is slowly turning into a vampire? Can vampires and humans really coexist in peace?
