Yuta's older sister, Miu's and Sora's stepmother, and Hina's mother. When their parents died, she raised Yūta by herself. She married Shingo when Yūta was in junior high school. At one point Yūta was mad at her because her husband had a previous marriage and because he already has two kids, Miu and Sora. She and Shingo went missing during their flight, which forced Yūta to take her kids to his custody to prevent them from being separated.
