Yoko (Mao Hamasaki), a female novelist, is frightened by the shadow of a ghost that appears nightly. Through an introduction by an editor she knows, Yoko asks a psychic, Miko (Yuria Ashina), to perform a Johrei (spiritual cleansing). As she is guided through the mansion, Yoko senses the presence of strong "feelings" that persist in this place. According to Yoko, it must be her former lover, Luna (Kana Miyashita). Luna committed suicide in this mansion. Right in front of her. She tearfully claimed that Luna's spirit was trying to possess her. That night, Miko witnesses Luna wandering the hallway. As a medium, Miko tries to get to the bottom of the matter by contacting the spirit.
