Nanami Sakamoto

Nanami Sakamoto (坂本 七美 Sakamoto Nanami) is the wife of Hidetoshi Sakamoto and the mother of Harumi, Natsuru, Akira and Fuyuki. She looks about as old to be her children's sister, despite her really being 42 years old. She is a housewife.

In Princess Princess, when Tooru and Yuujiro first meet her, they thought she was Akira's sister and wonder if she was older or younger than he is. After being told that she was actually his mother, they ask if she was his stepmother, but Akira not only confirms she is his real mother but also that she never had any surgery or other procedure to look young.
