Miya  

, ミヤ

The spirit hails from the Miyanoshita Hot Spring District and is known as a hot spring spirit. Despite being an archrival of Hakone, both consider themselves fierce competitors. Her objective upon arriving at the Hakone Yumoto district is not only to establish a grand hotel but also to diminish Hakones reputation and power. Unlike Hakone, who was one of the older hot spring spirits that had been slumbering for an extended period before awakening, this spirit retains some abilities even after her long sleep. Initially appearing as a 16-year-old girl, she can transform into a woman in her twenties when fully developed. She develops feelings for Touya and follows him around to be near him.
