Mother

Ai's mother lives together with her somewhat older husband. She has an even more voluptuous figure than Ai, to the point where her daughter refers to her as "the largest." Although she considers the growth of her daughters as a "family fate," she sometimes makes lighthearted remarks about the situation. Within the depiction of the family's bonds and growth, her character brings a humorous presence, making her an approachable and charming figure for viewers.
