高沢 葵

She is a physical education teacher at Aimine private school. Her husband is a fierce gymnast and a judo instructor in the security force. She has an old-fashioned personality and is very rigid when it comes to male relationships. She believes that sexual intercourse is meaningless for anything other than procreation, and considers male sexual desire to be dirty.

She is strong-willed and has more muscular strength than the protagonist, but in fact she has a maidenly side and is also shy. Her language is feminine, and uses "watashi" to refer to herself. She does not speak in a particularly masculine way.
