Nui

Nui is a Mushishi and the narrator of the anime series. Her voice can be heard in many episodes.

Nui's appearance is very similar to the series' protagonist Ginko. Due to her exposure to the Ginko Mushi, she has white hair and only her left eye (which has turned green). She is tall and usually wears a dark kimono. Since she doesn't have her right eye, she keeps it shut. Nui's appearance was different before being exposed to the Ginko, she had long, black hair, dark eyes, and wore a brighter kimono. Similar to Ginko, she smokes Mushi-Tobacco to keep Mushi away.

Nui is a Mushishi from an isolated yet beautiful village in the mountains. Due to her tendency to attract Mushi she rarely stayed in her village and often used to travel from place to place driving Mushi away. She still often used to visit her parents, friends, and her husband and child.
