Torikori lives alone on the outskirts of Ennakamuy after her husband's death, having raised her biological children, Oshtor and Nekone, independently. Though she appears young, her true age exceeds her physical presentation. Her personality embodies humility, calmness, and profound maternal compassion. As the adoptive mother of Haku, who assumed Oshtor's identity, she maintains a nurturing relationship with him. Torikori reveals she recognized Haku's true identity from the start yet never blamed or hated him for Oshtor's death. Instead, she regards Haku as a second son, acknowledging similarities between him and Oshtor. This acceptance offers Haku deep emotional solace, helping him process his grief and responsibilities. She often comforts him with embraces, strengthening their familial bond, which Haku reciprocates by calling her his mother. Torikori also experiences deteriorating eyesight, though its specific cause or progression remains undefined. Her narrative primarily focuses on her role as an emotional anchor.
