Bossun makes friends with a violinist while practicing for the upcoming Rock Festival, Sugisaki Ayano. He learns from her how fun music is, and in no time the curtain rises on the Kaimei Rock Festival!
But I was so happy when the two of them 
were pleased with my violin playing.
Mas fiquei tão feliz ao ver que os dois
 estavam apreciando o som do meu violino.
