1

Ten years ago, young Integra Hellsing ascends to the head of the Hellsing Organization after the death of her father Arthur. Her jealous uncle Richard Hellsing attempts to kill her, but in doing so awakens a dormant Alucard, who proceeds to kill Richard's men. It is Integra who shoots and kills her uncle, thereby becoming the last descendant of the Hellsing bloodline. Alucard declares his allegiance to Integra and becomes her loyal servant. In present day England, Alucard is called to duty to eradicate a vampire priest and his ghouls. However, a police girl named Seras Victoria is gravely injured in the process, and upon giving her a choice to live or die, Alucard turns her into his vampire servant. Later, on a mission to hunt down a vampire in the town of Badrick in Northern Ireland, Alucard meets and fights Father Alexander Anderson for the first time. (Source: Wikipedia)
