Sound! Euphonium (2015)

Kumiko Oumae, a euphonist disillusioned with music after a middle school competition mishap, enters high school seeking a new beginning. Drawn into the vibrant world of the brass band, she finds unexpected inspiration among her new and old friends, including novice tubist Hazuki Katou, seasoned contrabassist Sapphire Kawashima, and fellow euphonist Asuka Tanaka. Reuniting with childhood friend Shuuichi Tsukamoto, now a trombonist, and former bandmate Reina Kousaka, tension brews within the group. With aspirations for the national competition, the band faces hurdles, relying on their new advisor, Noboru Taki, to steer them toward success.
