Nushiyo Ookya (大家主代) is the 67 year old landlady of Matazuresou, which she inherited after the death of her husband. Her cold attitude toward children can be attributed to the fact that her husband and her 3-year-old daughter died in a traffic accident 30 years ago. She has very strict rules such as being very quiet in the corridors and not allowing pets. She spends her free time piling her collection of dentures into a tower. Which never succeeds, due to the interruptions of the Noharas, which cause it to collapse.
