Plot
The concert band of Daikichiyama Middle School, where euphonist Kumiko Ōmae and trumpeter Reina Kōsaka attend, obtains a "dud gold" at a band competition. Kumiko's comment on the impossibility to win the competition has caused a rift between her and Reina. Kumiko, now a first-year high school student at Kitauji High School, finds the school's band out of tune. She then befriends Hazuki Katō and Sapphire Kawashima. The three of them visit the band, during which Kumiko gets surprised to see Reina attending the same school and joining the band. After Kumiko decided to join the members as a euphonist, the band meets their new advisor Noboru Taki, who asks them about their goal for the year. The band decides to win the national band competition, but their first ensemble practice has ended poorly causing Mr. Taki to dissent from their plan to perform at Sunrise Festival. Mr. Taki holds practices with the band before their second ensemble practice. He becomes impressed with the result of the band's ensemble practice and agrees to help them with the Sunrise Festival. On the day of the festival, the Kitauji High School Concert Band's marching performance of the piece "Rydeen" garnered the attention of spectators. 

Mr. Taki announces an audition for the competition, where a 55-member band is required. During the Agata Festival, Hazuki gets rejected by Shūichi Tsukamoto after she confessed to him, while Kumiko and Reina, who have reconciled, play the piece "Ai o Mitsuketa Basho". Following the end of the audition, the members who will be competing are announced. Afterward, Reina is selected to be playing a solo piece instead of trumpeter Kaori Nakaseko. The result of the audition, particularly about Reina being selected for the solo part, is not received well, causing a rumor about Mr. Taki favoring Reina due to their shared history. Mr. Taki decides to hold a second audition between Reina and Kaori for the solo piece. After the audition, Kaori gives the solo part to Reina despite being selected by Mr. Taki. During an ensemble practice, Kumiko is struggling with a part of her piece. Mr. Taki then asks Asuka Tanaka to play that part solo, causing Kumiko to emotionally break down as she goes home. Returning to school, Kumiko is encouraged by Mr. Taki to continue practicing that part. On the day of the Kansai Band Competition Preliminary, Kitauji High School Concert Band performs the piece "Crescent Moon Dance". The band then wins the competition.
