Na een traumatische ervaring tijdens een regionale blazersbandcompetitie op de middelbare school, zweert euphoniumspeelster Kumiko Oumae de muziek af. Ze hoopt op een frisse start op de middelbare school. Maar het lot beschikt anders, want ze wordt omringd door mensen met een passie voor de schoolharmonie. Met de hulp van haar bandleden, zowel nieuwelingen als ervaren muzikanten, vindt Kumiko de motivatie om weer muziek te maken. Echter, binnen de band heerst pure chaos. Ondanks hun ambitie om zich te kwalificeren voor het nationale blazersbandkampioenschap, is zelfs deelname aan het lokale festival op dit moment een hele uitdaging. Tenzij de nieuwe bandleider, Noboru Taki, ingrijpt...
