Sound! Euphonium: Reina Kousaka

A first year who graduated from the same junior high school as Kumiko. Influenced by her father, a professional, she has been playing the trumpet since she was little, so she continues in the concert band club at Kitauji High School. She is stoic and has a sense of pride in her trumpet skills, though she still respects her upperclassmen. After their junior high won a bronze at a concert band competition, she and Kumiko had a falling-out.
