It's the school festival at Kitauji High School. Kumiko's sister insists on quitting college, while Taki reveals some things about his past with his wife.

The concert band begins taking itself very seriously to give itself the best chance possible of winning gold at Nationals. Unfortunately, the intense environment has some of the new recruits discouraged and intimidated.

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.

The final competition for the third-years is at hand. The Kitauji High School Concert Band performs together one last time in a bid for National gold.
