Kiniro no Corda: La Corda d'Oro

Kahoko Hino is a general-studies student at Seisou Academy — not one of the music students — whose life is upended when the musical fairy Lili notices she can see him. Lili was the spirit who once blessed the school's founder, and his reappearance to Kahoko is not random. He enters her into the school's prestigious annual musical concours, competing against the academy's top music students, over her considerable objections, and presses her until she agrees. She discovers she can play any piece on the magical violin he gave her, as long as she knows the melody and plays it genuinely. The competition, the practice, and the relationships that form around both drive the story forward.
