Kumiko and the others join the concert band, and they choose their instruments. Their eccentric senior, Asuka, still likes to mess with them.

Kitauji High School Concert Band is preparing their parts for the ensemble, but some students are fooling around when they should be practicing.

Kumiko and the others prepare for Sunrise Festival. Kumiko and Shuichi talk about Taki-sensei on the way home from school, when they run into Reina.

The band suspects Taki played favorites in choosing Reina in the auditions. Noticing the band's rising distrust of Taki and Reina, he makes a proposal.

Only three schools will be selected at the Kansai Concert Band Competition to compete in the Nationals. Will Kitauji High School be one of them?

With the competition over and the third-years graduating, Kumiko is left to sort through her feelings: Is it a love of concert band, of the euphonium, or of something else?

The three-day summer camp has begun, and members of the concert band are faced with a rigorous training regimen. Mayu hesitates to audition yet again, afraid that she'll take the soli part from Kumiko. Motomu speaks to Midori in private.

Taki decides that the band will choose the euphonium soli player by voting on one final audition. Kumiko then decides that they should choose based on sound alone, and so the two of them audition anonymously.
