Volg twee beste vrienden die in een landelijk Japans dorp wonen: Yoshiki en Hikaru. Ze groeiden samen op en waren onafscheidelijk... tot de dag dat Hikaru terugkwam uit de bergen en niet langer zichzelf was. 'Iets' heeft Hikaru's lichaam, herinneringen en gevoelens overgenomen... en alles wat ze weten begint te ontrafelen.
