The old school building is haunted by the ghost of the German composer Ludwig van Beethoven, which plays a piano and curses people through the song Für Elise, stating that they will die if they hear the song four times; he can accomplish this by making his victims hear his song through various objects, even ones that could not normally play music. Satsuki is cursed when she accidentally hears the piece while helping the music teacher move some boxes to the old building. In the end Momoko, being possessed by Kayako, seals him inside a metronome.
