An unnamed Pastor had arrived and later kidnapped and killed many people, its first victim being a child in Cheddar Village. Later on, Integra Hellsing takes command of a small Hellsing unit in Cheddar, after hearing reports of people in the village going missing. D11 teams had originally been sent to investigate, but after several deaths, Alucard is deployed. Seras Victoria, a young police working for the London Police Department, is forced to fight her colleagues that are now turned into Ghouls. Seras soon finds herself trapped between the vampire priest and his army of Police Ghouls, fully equipped with armor and guns. Luckily, Alucard, Hellsing's Agent, comes to the rescue and kills the remaining Ghouls.
