Blood: The Last Vampire

In post-war Japan, a mysterious new student enrolls at a school on a US Air Force base, where she demonstrates her antipathy for academia by strolling into the matron’s office and dismembering a girl who was feeling ill. It turns out that the new kid is Saya, a vampire assassin hired by the authorities to rid the base of a nasty infestation of Chiroptera monsters - shape-shifting demons that can only be killed by inflicting massive blood loss, i.e. hacking them apart with a specially forged katana. You’ll almost feel sorry for them. Short, violent and visually arresting.
