Sound! Euphonium

At the start of high school, Kumiko Oumae visits the school's brass band club with classmates Hazuki and Sapphire. She played in a brass band during junior high, but unlike her companions, she hesitates over whether to join again. The decision becomes more complicated when she encounters former classmate Reina Kousaka, whose presence brings back memories of a junior-high competition and the unresolved experience Kumiko associates with it.
