A girl living in Yuba's village with her parents and her older brother Shin. When she was still a child, her parents died after an epidemic, and she and Shin became orphans. They were raised with a little help from all of their neighbors. Due to being born with the capacity to use spirit arts, just like Ruri, they began to learn them together with her from Yuba, who treated her almost as a sibling. That way, she became Ruri's childhood friend.
