Hellsing Ultimate (2006)

In the endless battle between man and the supernatural, one organization stands out: Hellsing, which specializes in dealing with paranormal threats. One day, on a mission to free an English village from a ghoul attack, the leader - Sir Integra Fairbrook Wingates Hellsing - sends her most powerful agent: a vampire known as Alucard. During the conflict, a police officer, Seras Victoria, gets caught in the crossfire and is resurrected as a vampire. Now she must assume her new identity if she wishes to endure the oncoming battles. This anime adapts the manga of the same name, although its plot is vastly different from its source material.
