Nagi's mother, who passed away when Nagi was young. She was known for telling Nagi that she'd always watch over her "like the sky and the stars"—a promise that clearly stuck with the kid. According to Hatsuho, Isumi's mother, she bore a striking resemblance to Hayate, which might actually explain why Nagi's so attached to him. Her grave is in Shimoda, and Nagi makes a point of visiting every year.
