Ep 1 – “Night of Vampires” / “Vanpaia no Naito” (ヴァンパイアの夜)
Yuki Cross recalls her earliest memories, in which she was attacked by a vampire and saved by the Pureblood vampire Kaname Kuran. In the present, she attends the Cross Academy, a school founded by her adoptive father, Headmaster Kaien Cross, and she works as a “Guardian” with vampire hunter Zero Kiryu to protect the human students of the “Day Class” from the vampires of the “Night Class”, an arrangement created by Kaien to foster better relations between vampires and humans. That evening, Yuki discovers a pair of male Night Class students, Hanabusa Aido and Akatsuki Kain, threatening to feed on a pair of female Day Class students. Yuki attempts to stop them, only for Hanabusa to drink some of her blood from a wound she got from climbing down a tree. They retreat only after Zero arrives and threatens them with his anti-vampire gun, Bloody Rose. Kaname takes Hanabusa and Akatsuki to Kaien for punishment while the female students’ memory of the event is erased. Cleaning up for bed, Zero shows signs of vampirism by becoming enticed by the sight of Yuki’s neck while she is drying her hair.
