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

The band is hard at work preparing for the audition and the competition. Aoi has trouble with her part, to which Taki says, "when will you be better by?"

The 10 members of the concert band club who failed Taki's audition form "Team Monaka" to support the club members participating in the Kyoto Concert Band competition. Even as they support the performers, they continue to hone their playing, and make monaka-shaped good-luck charms to hand out to their club mates before the competition. Although they didn't play in the competition, they still had things they had to do. But on the day of the competition, the members on their way to the concert hall receive a shocking message! This is Team Monaka's hot summer story.

Having won first place at the Kyoto competition, Kumiko and the band are preparing to compete in the Kansai competition. A shadow looms over them when an old member, Nozomi Kasaki, enters the picture.

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?

Asuka's mother wants her to quit the concert band. This upsets everyone -- including her mother.

Taki decides to let the band executives choose their competition piece this year. The leadership deliberates on this decision while trying to get the rest of the band ready to perform at the Sunrise Festival.

Members of the concert band are given a brief, three-day summer break that quickly fills with plans of all sorts. Some of the third-years attend an event to gather information on different colleges and plan their futures.

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.
