Momoe Okonogi is a second-year junior high school student of Seikyou Academy and a member of the Third Newspaper Club who stumbled upon one of the Seven Mysteries of Seikyou Academy and she eventually becomes an informal member of the Paranormal Investigation Club. She is indebted to Teiichi for saving her from the Underground demon legend (which was fabricated by Yuuko) and looks for many ghost stories in the school to help the club. She is the only member of the club that cannot see Yuuko.
