Vampire Prostitute

This unnamed female model appears in the beginning of the first episode of the Hellsing anime created by Gonzo. At first, she appears to be a prostitute, with her client's dialogue implying that he's a vampire; it later turns out that she is actually the vampire or a Draculina. In the anime specifically, she's the first ever vampire to get killed on-screen, and also Alucard's first, on-screen kill.
