La Corda d'Oro

Kahoko Hino is a student in the General Education section of Seiso Academy. One day she runs into Lili, a musical fairy, who grants her a magical violin and a place in the school's annual musical competition. Kahoko refuses, only to be pressed on by Lili until she accepts the instrument and place in the competition. As she practices, Kahoko is amazed that she can play any musical piece as long as she knows the tune and plays it with her heart. As the competition goes on, she becomes more and more attached to the people she is trying to compete with.

Hino is a 2nd year student at Seiso Academy and is in the General Education department. She has a warm and friendly personality and is very honest and straightforward, as shown from the way she expresses herself through her violin. She remains oblivious throughout the story to the attention of the males surrounding her. She lives with her mother, older sister and older brother, though nobody knows who is her father because there is no evidence. She is also half-hearted. She was given a violin by the fairy Lily for being able to see him. At first she was very nervous about this but soon finds that with the help of the other characters she has found her passion. She also changes the lives of others such as Len Tsukimori when she helped teach him that music is about heart and not just talent, or helping Shimizu Keiichei finding his "sheet music".

His mother is a famous pianist, and his father is a violinist, who both think that music should be played from the heart, but Len did not understand what his parents had meant on that matter, until he had met Hino and fell in love with her. He came to realize these feelings when Hino showed him that music is full of heart and not just dependent on talent. He worries about her, especially when she had hurt her hand trying to help him.
