sounds of a haunting piano can almost always be heard from the kamishiro mansion. Day or night, rain or shine. Ever since the 'suicide' of tenma tsukasa..that piano could be heard playing nonstop. Outsiders think that it's the owner of the manor playing in remembrance of his late husband..but in reality..it's the ghost of tsukasa tenma. Playing and playing over and over. Only rui could see him. Only rui.
