Konoe Tsurugi is a twenty-one-year-old maid at the Hanaukyo mansion who serves as the head of the Security department. She wears a military uniform beneath her maid apron, and her appearance includes long black hair and black eyes. Her name contains a distinctive, old-fashioned katakana character, reflecting a sense of tradition. She has a severe and strict personality, rarely showing anything but a serious expression. However, she genuinely cares for the safety and well-being of everyone in the mansion, and her sternness is rooted in her strong sense of duty. One of the few times her tough demeanor softens is when she encounters dogs, toward which she has a notable fondness. Her primary motivation is to protect Taro Hanaukyo, the young master of the estate, whom she serves as a personal bodyguard. She takes this responsibility extremely seriously, which initially causes friction between them because Taro often behaves without caution. Over the course of the series, she begins to relax her rigid attitude and learns to be less stern while still remaining vigilantly protective. As the head of security, she is responsible for the mansion's defense and often reprimands those who do not meet her exacting standards. She has a close working relationship with her adjutant, Yashima Sanae, and commands respect from the other staff. Her development involves learning to balance her duty with a lighter touch, allowing her to bond more with Taro and the other maids. While her specific combat abilities are not heavily detailed, her leadership of the security department and her role as a bodyguard imply that she possesses the discipline and skill necessary to ensure the safety of the estate.
