Deceased mother of Nagi. She often said to Nagi that she would always look after Nagi as the sky and the stars. According to Saginomiya Hatsuho, Isumi's mother, she had a similar face to Hayate—which might be one of the reasons why Nagi is so fond of him. Her grave is at Shimoda, and Nagi visits it every year.
