Yuri Shirahane is the supernatural guardian of the hot springs at Miyama-kan inn, sustaining their spiritual essence. Her ethereal presence is marked by black hair and grey eyes. When Makoto Yukami visits for the 100th time, he accidentally absorbs her powers. This loss disrupts the springs' normal function and leaves Yuri vulnerable. Though still connected to the inn, her direct role in its daily operation becomes unclear. Makoto's subsequent employment ties her fate to his presence. Interactions with the inn's four poster girls imply she holds a respected position among them, while specifics of their dynamics remain unexplored. Documented material doesn't explore further development, backstory, or an expanded role beyond the initial OVA and source.
