A descendant of modern-day humans. She is Kohaku's elder sister and the daughter of Kokuyo. She serves as the priestess in Ishigami Village. She is a kind, gentle, and demure young woman. She previously had a submissive personality, but after making a full recovery from her illness, she is shown to be more optimistic and positive and even shows a more tomboyish side, immediately making a full dash running around the village. Despite this, she is still much more feminine than Kohaku.
