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.
But my little brother's been a 
brat lately, so maybe that counts?
Aber mein Bruder ist neuerdings 
ein richtiger Bengel, zählt das?
Pero mi hermanito últimamente se ha 
vuelto algo malcriado, ¿eso cuenta?
Aunque mi hermano pequeño cada 
vez está más insoportable. ¿Eso cuenta?
Mais mon petit frère est en pleine 
crise d’adolescence, en ce moment…
Mas meu irmão mais novo anda
uma peste, será que isso conta?
