Sound! Euphonium, the Movie -Our Promise: A Brand New Day-

Last year, Kitauji High School’s concert band competed in the National Concert Band Competition.
Now, second-year Kumiko Oumae and third-year Tomoe Kabe must mentor the incoming “junior” members. Since the concert band advanced to Nationals, many freshmen are eager to join, but only four members apply to play the bass instruments –

Kanade Hisaishi, who appears easy-going,

Mirei Suzuki, who doesn’t try to fit in at all,

Satsuki Suzuki, who wants to get close to Mirei, and Motomu Tsukinaga, who is very private.

First, there’s the Sunrise Festival, followed by auditions and then the competition.
The concert band is aiming to win the “Gold Award” but problems keep arising…!

The tumultuous days of Kitauji High School’s concert band begin now!
