Hellsing Ultimate

Hellsing is a secret British government organization dedicated to protecting the public from supernatural threats. Its leader, Integra Fairbrook Wingates Hellsing, commands trained soldiers, but her greatest weapon is Alucard, an immensely powerful vampire who hunts other creatures of the night. Alongside Integra's butler and Alucard's vampire subordinate Seras Victoria, Hellsing confronts ghouls and vampires while also facing organized enemies. A rival secret organization connected to the Vatican and the mysterious group Millennium turn the supernatural conflict into a much larger struggle between heavily armed factions.
