Sir Integra Hellsing is a 22-year-old member of the Protestant Knights, the leader of the Hellsing Organization, and the current master of Alucard. Integra has a very collected attitude, rarely allowing her emotions to get in the way of business. However, she is sometimes prone to bouts of anger. As the Hellsing family is "on a mission from God," she values her duties to protect the United Kingdom, its Queen, and the Anglican Church above everything else. For her, failure is not tolerated, especially her own. She runs the Hellsing Organization with charisma and patriotism, and she is one of the few people who can stand up to the force of Alucard's personality and command his respect.
