Hellsing (2006)

London, a city of mist by day and a hunting ground for the non-living by night, is constantly defiled by the blood of vampires and other ghouls. To counter this threat, the Hellsing organization, a secret society and member of the Round Table, which has sworn to eliminate the vampiric menace on Protestant soil, stands guard. At the head of this organization is the direct descendant of the famous hunter Sir Integral Hellsing, a woman with an iron grip, a grip that holds one of the most powerful Nosferatu on a leash: Alucard. A demon in the service of a human, pointing his imposing pistol at his unworthy brethren, he hunts with an amused air, ready to mercilessly destroy all who stand in his way. Joining this cheerful family are Seras Victoria, an ex-police officer who became Alucard's fledgling, as well as Walter, the old butler and former cleaner, and many others. All of them will have to face powerful enemies, be they demons or, even worse: humans!!!
