Vampire Prostitute

She appears in the beginning of the first episode, as Alucard's first kill on screen. 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. She wears the millennium eye, also seen on Jan Valentine's hat, on her necklace, implying that she may be a member of Millennium.

Trivia

 * An identical model, though in a red dress instead of a black one, is staggering around in the beginning of the second episode, and attacks Kim. She is killed by a Hellsing Sniper after Seras can't get the will to shoot.
