Reina Kousaka

Reina Kousaka is one of the main characters of Sound! Euphonium series. She is a first-year trumpet player who plays in the Kitauji High School Concert Band, continuing on the same instrument from elementary and middle school. She was also a member of the concert band club at the same junior high school as Kumiko Oumae. Reina is a teenage girl with an average build and a considerably shorter height, described to be beautiful in the light novels with a light complexion. She has long, straight black hair which is about lower-back length, which she sometimes wears in a ponytail. She has two long strands of hair laid on her shoulders and two smaller strands framing her face. She has purple eyes and she is usually seen wearing a normal Kitauji High School uniform for first-year female students. Reina is a calm and quiet girl who is very individualistic and passionate about music. Although she has a polite manner, especially to her seniors, she is told that she is not taken so well by others because she usually wears a surly expression. She can be somewhat cold and upset with others when someone talks ill about Noboru Taki, whom she has a crush on for which people sometimes comment on her. Reina is portrayed as a somewhat mysterious girl who doesn't open up to people easily, which is why it is on the principle that she does not attempt to be friends with someone who doesn't interest her. She is at times standoffish and can often speak very bluntly when it comes to her pride as a musician. Because of this, she has had trouble making friends in the past. She appears to be distant and emotional, focusing solely on her drive to succeed. However, as Reina grows closer to Kumiko Oumae, she begins to let her guard down and a different, friendlier side of her personality is revealed. After becoming friends with Kumiko, she grows close to her and supports and cares for Kumiko deeply. She shares with Kumiko her intentions to become truly special, which is why she plays the trumpet. She claims that with her trumpet, she will become her own kind of special. She cherishes her trumpet dearly, which was given to her by her parents when she was a junior high school student. Throughout the series, Reina appears to grow more empathetic, as she apologizes in later episodes for her rude behavior for the first time on screen. Later in the series, Kumiko mentions that Reina has changed, as she is willing to become friends and interact more with other people such as Hazuki Katou and Midori.
