The "elite student in music room 2" turns out to be Haruki's delinquent classmate, Kazusa Touma.  With his characteristic pushiness, he tries to get her to join the light music club.  But his pushiness backfires, and only makes her more annoyed.  Setsuna gets irritated... no, involved, and approaches Kazusa secretly.
That I want you to play with us, 
just like Kitahara-kun does.
Dass ich will, dass du mit uns spielst, 
genau wie Kitahara-kun das will.
Que yo quería lo mismo que Kitahara-kun; 
que tocaras con nosotros.
Sabía que yo quiero lo mismo que 
Kitahara-kun: quiero que toques con nosotros.
Tout ce que je voulais te dire,
Que, assim como o Kitahara, eu
quero que você toque com a gente.
