A new year signifies a new beginning, and that seems to be the case for Kitauji High School’s concert band. Following the graduation of the third-year seniors comes the entrance of the first-year juniors. The band members put in their utmost effort in practicing for their goal—to enter nationals. The now second-year Kumiko Oumae, along with her friends, is met with the new and quirky batch of first-years, resulting in friction and conflict between the band members. However, as time passes, their inner feelings slowly unravel, but not every conflict is as easy to solve as the other. The trust and bonds between the band members will be challenged as they push forward for their regionals.

After swearing off music due to an incident at the middle school regional concert band competition, euphonist Kumiko Oumae enters high school hoping for a fresh start. As fate would have it, she ends up being surrounded by people with an interest in the high school brass band. Kumiko finds the motivation she needs to make music once more with the help of her bandmates, some of whom are new like novice tubist Hazuki Katou; veteran contrabassist Sapphire Kawashima; and band vice president and fellow euphonist Asuka Tanaka. Others are old friends, like Kumiko's childhood friend and hornist-turned-trombonist Shuuichi Tsukamoto, and trumpeter and bandmate from middle school, Reina Kousaka. However, in the band itself, chaos reigns supreme. Despite their intention to qualify for the national band competition, as they currently are, just competing in the local festival will be a challenge—unless the new band advisor Noboru Taki does something about it.
