Hellsing

In Queen Victoria's England, the Organization Hellsing, heir to the Royal Protestant Knights founded by Abraham Van Helsing, exists to protect the country from any supernatural threat. At its head is Sir Integra Fairbrook Wingates Hellsing, the last of her family, who took over leadership as a child after her father's death. Her greatest asset is Alucard, an ancient and very powerful vampire who swore loyalty to the Hellsing after being defeated by Van Helsing a century earlier. Alongside him and the loyal butler Walter, the organization battles vampires, ghouls and other supernatural beings that threaten the kingdom. The anime series, produced by Gonzo, aired on Fuji TV and features Jouji Nakata and Fumiko Orikasa in the cast.
