Hellsing

Hellsing follows the antiheroic vampire, Alucard, and a police girl, Seras Victoria, [who is turned into a vampire by Alucard while fighting another vampire], two vampires employed by the vampire-extermination group of England, the Hellsing Organization. Slowly but surely, through their active duty, they find a new breed of vampires beginning to arise. Their job is to find their source and exterminate them, and so Alucard would meet his toughest enemy, a undead!
