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.
She's lazy, violent, and 
doesn't care about anything.
Sie ist faul, brutal und ihr 
ist prinzipiell alles egal.
Es floja, violenta y no se preocupa por nada.
Es una vaga, algo 
violenta y todo le da igual.
Quoi qu’il arrive, 
elle reste de marbre.
Ela é preguiçosa, violenta e
não se importa com nada.
