Rosario + Vampire

Tskune Aono,a subpar student both academically and physically, is accepted into a mysterious high school. His first day of school is defined by his encounter with Moka Akashiya,a vampire that is enchanted by the scent of his human blood. Having quickly discovered that his new school is a school for monsters that have a mortal intolerance for humans, Tsukune tries to find a way to escape from the school. Upon his attempt to run away from the school, Tsukune has a confrontation with Moka. A fight with a delinquent student named Saizo quickly complicates and endangers Tsukune's life right before he accidentally removes the rosario on Moka's neck. Tsukune learns that Moka's true form has a different personality, which easily defeats Saizo. He faints from his beating given by Saizo and wakes to find normal Moka caring for him. She tries to help him wipe off blood coming from a cut, but ends up sucking his blood.
