Len Tsukimori

A surly, blue-haired, violin player who normally behaves contemptuously toward everyone. He was a child prodigy, coming from a family of musicians. His mother, Misa Hamai, is a very famous pianist and his father is a well-known violinist. Because of this, many people take his brilliance for granted. He seems very cold towards those that he comes into contact with, even his admirers, to whom he rarely pays attention to.
Before he met Hino he didn't think that music was enjoyable, though after spending time with her, he began to slowly enjoy music and his music changes because of her. He slowly warms up towards Hino and even gives her advice on how to hold and stand properly with the violin. People think that he acts harshly towards Hino, but deep down in his heart he is really concerned about her (though he may not show it). As the series progresses, he realizes his feelings for her. He's slowly affected by Hino and his mother says that he has changed his character. His mother knows that Hino is the one that affected him or changed his personality.

Hihara Kazuki
Hihara is an energetic third year at Seisou who plays the trumpet. He is tall and in shape (he runs every morning), and has green hair and eyes. He's aggressively friendly and outgoing and has little sense of social boundary. Hihara has an enormous appetite, as he is constantly eating (especially baked goods). He quickly befriends Kahoko. In the middle of the series, he starts to call Kahoko "Kaho-chan", instead of the usual "Hino-chan", this suggesting he has a rather obvious crush on the girl. He also admits to Azuma that he has a crush on Kahoko, saying "don't make fun of me" when asked. Basketball is one of his favorite sports.


Tsuchiura Ryotaro
Another second year General Education department student, and Hino's friend. He and Kahoko met after he ran into her, nearly knocking her down a staircase, saving her in the nick of time. Their friendship eventually grows, and she even confesses she knew nothing of violin playing. He is a very gifted pianist but quit playing in public because of an unpleasant experience at a junior concert. Ryotaro is the star of the soccer team, being very skilled at the sport (and even outdoing some third years). After he helped Kahoko in the first round of the concours by being her accompanist, he, as well, joined the concours. He does not like Len Tsukimori, and they often get into many disagreements. His feelings for Hino gradually deepens as the series progresses.
