ヴァンパイア騎士

Yuki Cross, adopted daughter of Cross Academy's headmaster, works as a school guardian to keep one secret: the elite Night Class is made up of vampires, and the human Day Class must never find out. She patrols with her childhood friend Zero Kiryu, who hates vampires after they destroyed his family. Yuki's own past begins on a snowy night ten years earlier, when the Pureblood Kaname Kuran saved her from a vampire attack.
