Hellsing follows the antiheroic vampire, Alucard, and a police girl-turned-vampire, Seras Victoria, 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. This newly developed breed is created through new technology made by an unknown organisation with the purpose of overthrowing the most powerful vampire known to mankind—Lord Alucard. Victoria has the problem of still wanting to hold on to her non-existent humanity, refusing to drink blood, which is provided, making her weaker than usual. Together they fight and try to uncover the source of this new technology.
