After Ginko was orphaned by a landslide, she took him in and cared for him. She taught him about the Mushi but kept a secret from him.
The Mushi in the pond near her home are responsible for her hair turning white and the loss of her right eye. When the other eye is eventually lost, the afflicted person transforms into a shadow, consumed and swept away by the great Ginko Mushi that resides in the pond along with the darkness Mushi.
She is a Mushi master who has already lost her hair color and her right eye to the Mushi living in the pond near her house.
She can be heard narrating some of the opening and closing lines of the anime.
