The water on this mountain is believed to house spirits, and there is a teaching from this region that “humans are born from water and return to it at the end of their lives.”

Several peculiar rituals and customs still exist on this mountain, and many bizarre and unfortunate occurrences have supposedly taken place here.
This story takes place on Mt. Hikami, a mountain believed to be a sacred place, and revolves around Yuri Kozukata, Ren Hojo, and Miu Hinasaki who act as the three protagonists whose stories are interwoven in this mysterious and dream-like tale.
