Blood: The Last Vampire

In 1970s Tokyo, Saya, a 400-year-old half-human, half-vampire girl, hunts full-blooded vampires in partnership with humans. Raised by a man named Kato, she works with "The Council", a secret society that has been hunting vampires for centuries. Saya's motivation goes beyond duty; she wants revenge against Onigen, the oldest of the vampires, who murdered her father. When Saya goes undercover as a student at Kanto High School, she teams up with Alice McKee, the daughter of the base's general, to find and slay Onigen, her mother. The two are aided by Saya's samurai skills, but ultimately, Saya's true identity is revealed and she must confront her mother.
