Haruki is entranced by Setsuna's singing on the rooftop, and plots to get her to join the Light Music Club no matter what.  But she hates standing out, so convincing her is incredibly difficult.  Meanwhile, the club has an even bigger problem.  The elite student from Music Room 2 he was trying to persuade to join his club as the keyboard player isn't a member of the Music Class, it's a mysterious person whose class and identity are a total unknown.
Is this the curse of the student who 
jumped out the window twenty years ago?
Ist das der Fluch des Schülers,
der vor 20 Jahren aus dem Fenster gesprungen ist?
¿Esta es la maldición del estudiante 
que saltó del salón hace 20 años?
¿No será esta la maldición del 
estudiante que se suicidó hace veinte años?
É a maldição do aluno que
pulou da janela há vinte anos?
