Mitsuba no Haha

She is the mother of Mitsuba Sosuke, working as a nurse in her daily life. After losing her son in an accident, she has been living alone, with thoughts of him never leaving her heart. One day, she crosses paths with Nino and Hikaru at the cemetery, where she shares with them the story of how much Mitsuba cherished photography during his lifetime. Warm and gentle by nature, with a touch of absentmindedness, she continues to show heartfelt affection toward her son's friends despite the loneliness she carries within.
