Makoto's wife. Also 25 years old, Makoto is the first man she has ever kissed or had sex with. (even through the series she is fully determined to overcome her limitations and be a better lover to Makoto), as well as insecure about her looks; she is unaware how beautiful and charming she is. She is also the target of attention by many men (although their behavior is – compared to the women who adore her husband – mostly passive longing). She additionally has the knack of befriending most of the women whom she should consider her rivals for Makoto's affections (Makoto's colleague Makie Sugiyama is a notable exception). When she was in high school, she was a member of the Tennis club.
