Vampire Knight tells the story of Yuki Cross. The earliest thing she remembers is being attacked on a snowy night by a vampire, and being rescued by Kaname Kuran, who is also a vampire. The story takes place 10 years after that event, Yuki is now the adopted daughter of the Headmaster of Cross Academy. She and her longtime friend Zero Kiryu keep peace at the academy, making sure no problems arise between the Day Class (humans) and the Night Class (vampires). However, the peace they try to keep is fragile, and personal feelings begin to interrupt their duty.
Based on the manga by Matsuri Hino
Could use more screen time for the Night Class using their abilities which you get little glimpses of but the show is mainly about Yuki regaining the memory of her past anyway.
Many readers of the Vampire Knight manga series understands the future relationships between Yuki, Zero, and Kaname and where they end up but few get such a detailed exploration of their beginnings. That's where this series comes in. Although Yuki is slightly annoying in the overly dramatic and childishly dependent way the one character I wound up liking the most was Zero because in the end he was the least crazy one of the bunch.
Vampire Knight is available in English and Japanese with Subtitles.
