Plot
While walking her guard rounds in the country, Doris Lang, the orphaned daughter of a deceased werewolf hunter, is attacked and bitten by Count Magnus Lee, a 10,000-year-old vampire lord (also known as a Noble) for trespassing in his domain.
Doris later encounters a mysterious vampire hunter, known only as D. Infected from Count Lee's bite, she hires D to kill the vampire and save her from becoming one. While in town with D and her younger brother Dan, Doris is confronted by Greco Rohman, the mayor's son, who offers to help if he has Doris for himself, but she refuses. D requests that the authorities, including Greco's father, the town sheriff, and Dr. Ferringo, should hold off Doris' incarceration at the local asylum until he kills Count Lee.
That night, Doris's farm is attacked by Rei Ginsei, Count Lee's servant, and L'Armica, Count Lee's daughter, who is highly prejudiced against humans. During the battle, Rei reveals he has the ability to twist space around him. Because of these powers, D's attacks are redirected onto himself, but he quickly recovers from his wounds, revealing him to be a dhampir. After fending off L'Armica, he orders the pair to leave with a warning to Count Lee.
