Kumiko Oumae

__Height:__ 162 cm __Instrument:__ Euphonium Kumiko enrolled in Kitauji High School after long hoping to wear the uniform. She wasn't particularly dead set on it but decided to join the wind ensemble and continue playing the euphonium. She has a habit of immediately saying what she's thinking and changes her mind easily. She is very preoccupied with something she said to Reina at a contest in junior high school.
