Fuuko is a first year student at Tomoya's school (Technically, her age is same as Tomoya's), but she is always alone by herself, making wood carvings of starfish with a small knife to give to others as presents for her sister's upcoming wedding. Whenever Fuuko sees something she thinks is incredibly cute, she completely loses awareness of her surroundings, which Tomoya takes advantage of by playing a variety of pranks on her. In ~After Story~

Sir Integra Hellsing is a 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.
