Michinori's wife and the mother of Wakana and Saya. She is very loyal and obedient to her husband sometimes to the detriment of her daughters...

She was Yukariko's childhood friend and knew she had love for her brother. However, she was forced to marry Michinori, whom she did not yet know.

She has never been angry that her best friend slept with her husband. She even had secretly arranged meetings for her that Saya could visit Yukariko and Haruta.
