Dark Moon: Tsuki no Saidan

Sooha has spent her life hiding her unnatural strength because people were quick to call her a vampire and even blame her for the death of her childhood friend. Hoping for a clean beginning, she transfers to the night classes of Decelis Academy, a place she believes creatures like vampires and werewolves cannot enter.

Instead, seven mysterious boys are drawn to her almost immediately, led by the friendly Heli, and each carries a power and a history Sooha does not understand. When a murder in the city is blamed on a vampire, the truth begins to surface: the boys themselves are vampires, and their past is connected to Sooha far more deeply than she imagined. With werewolves closing in as well, she is pulled into a centuries-old conflict between the very beings she was taught to fear.
