三沢 千晶

Kouta's wife and Chisato's younger sister. Unlike her sister, she is proactive, assertive, and energetic. Chiaki and Kouta started dating during their college years, moved in together, and had a child shortly after graduating from college. Although she was initially open about her sexuality, the responsibilities of motherhood have made her feel fulfilled in her role as a mother, and she is not currently seeking a sexual relationship.
