She had originally intended to not join the concert band, but decided to join, along with her new friends and continued, albeit unwillingly, to 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. She speaks standard Japanese, a rarity in Kansai. She is easily swayed by the opinions of others and is an indecisive person. She dislikes her character because she cannot make her wishes known to others.
Her school bag is plain, and it seems that she is not interested in over the top, fancy stuff. She is an in-door type of person and she does not get along with sports-oriented people, except for Hazuki. Kumiko is also very friendly and polite, but she can be awkward sometimes and quite shy sometimes. However, she has it easy to make friends for accepting other people and she also have a quite care-free personality. Also, Kumiko knows when to be serious and not, and she is also very passionate about music.
Kumiko is a young teenage girl seemingly slightly above average height. She has shoulder-length, light brown, curly hair, gold-brown eyes and fair skin. In junior high, she had her hair tied into a ponytail at the back. Kumiko is usually seen with a normal Kitauji High School uniform for first year-students. [Source: wikia]
