Yukariko Sanzenin

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.
