Sanae is Nagisa's mother. Normally she's very childish and a cry-baby, but when needed she can be very strong-willed and dependable. She runs the Furukawa Bakery with her husband Akio. She often tries out strange concepts to make breads that are anything but edible and never get sold. Outside of the bakery, she tutors children. She's quite proud of the way people often mistake her for Nagisa's older sister because of her youthful appearance.
