Na hun succes in de kwalificatieronde voor de Kansai-regiowedstrijd, richt de harmonie van de Kitauji High School zich op hun volgende optreden. Ze benutten hun zomervakantie optimaal door deel te nemen aan een trainingskamp onder leiding van hun bandleider Noboru Taki en zijn professionele muzikantenvrienden. Kumiko Oumae en haar vrienden blijven vastberaden om goud te halen op de Kansai-wedstrijd. Problemen ontstaan echter wanneer een voormalig bandlid interesse toont om weer toe te treden, wat onaangename herinneringen oproept bij de tweedejaars. Bovendien komt Kumiko meer te weten over het verrassende verleden van haar leraar en de motivatie achter zijn wens om de band naar de overwinning te leiden. Het bereiken van de nationale kampioenschappen vereist hard werk en de onverzettelijke toewijding van elke student zal op de proef worden gesteld.
