Yuuko Kanoe

She is a ghost girl who died inside the oldest building of Seikyou Academy. She lost her memories and eventually became a wandering spirit. Sixty years ago, the village where Yuuko and her family lived was suffering through a terrible plague. Yuuko and her sister, Yukariko, soon began overhearing whispers in the village that it was their family's fault that the illness had come. For hundreds of years, the Kanoe family was responsible for a shrine to a Mountain God; to prevent the god from cursing people, an offering of one's "most precious thing" to Akahito-sama, the god's messenger, was required - that is, a human sacrifice. In recent years, the shrine was lost and fell into disrepair. Anime: Dusk Maiden Of Amnesia
