Kumiko Oumae

Kumiko Oumae is the main protagonist of the ''Hibike! Euphonium'' anime and light novels.

Kumiko is a freshman euphonium player who enrolls at Kitauji High School with the original intent of avoiding the concert band, but is coincidentally roped into joining along with her new friends, Sapphire and Hazuki. Throughout the series she begins to change her mind about the idea of starting anew.

Appearance
Kumiko is a young teenage girl with an average height and build. She has curly light brown hair which is shoulder length, amber eyes and fair skin. In scenes of Kumiko in junior high, she has her hair tied into a ponytail. Her hair is unique compared to other characters making her stand out as the main character. Kumiko is usually depicted in a normal Kitauji High School uniform for first-year female students.

Personality
Within the story of ''Hibike! Euphonium'', Kumiko is an ordinary girl to which interesting things happen. She is surrounded by characters that drive or instigate dramatic situations. Although she occasionally has a hand in the events around her, Kumiko mostly plays the role of a bystander, witnessing enough situations and exchanges that she always receives both sides of a story. As a willing and nonjudgmental listener, she easily befriends everyone she meets and accepts both their flaws and strengths. Due to this nature of Kumiko as a narrator, ''Hibike! Euphonium'' has no main antagonist in the series. However, Kumiko dislikes her own personality because she knows she is a poor communicator who has difficulty making her wishes known to others, and so often listens instead of speaking.

Kumiko is mostly friendly and polite, but she can be awkward and blunt sometimes due to her quirky habit of accidentally blurting out the first thing on her mind without restraint or tact. This lack of a filter is part her impulsive streak, a trait which also led her to enroll at Kitauji for a reason as trivial as its' uniform design, and also to accidentally ask Reina Kousaka to attend the Agata Festival with her. She also has a habit of dwelling on past situations to the point of obsessing over them in her head, such as her awkward encounter with Reina prior to entering high school.

Kumiko speaks standard Japanese, which is rare in Kansai. Her school bag is plain, and it seems that she is not interested in anything "over-the-top". She is an indoors type of person and she does not get along with sports-oriented people, except for Hazuki. In addition, Kumiko sometimes compares herself to others too frequently. This is why she often puts up a "good-girl" face, but in reality, she is actually really distant.

Over the course of the series, Kumiko grows more and more passionate about music and life in general, training hard to play the euphonium flawlessly as she finds the motivation and strength to become a better musician and better person.
