Akiyuki's mother. A strong-willed woman who cares deeply about her son and her typically, overworking husband. Although the relationship between husband and wife is strained because of his frequent absence from the household, she remains with him for the sake of their child. She is a resolute woman, who, upon discovering that her child had gone missing, takes it upon herself to try and find her son, regardless of whether or not her husband is compassionate enough to abandon his work to help her. She has a very familiar relationship with Haru, and seems to be able to entrust her son's wellbeing to her, when later Haru was able to confirm that her son is indeed alive.
