At Seiso Academy, students are divided into General Studies and Music Studies, each distinguished by their uniform colors. One day, while hurrying to class, Kahoko Hino, a General Studies student, encounters Lili, a fairy in search of someone who can see her. After their brief meeting, Kahoko is left curious. Later, the school announces the participants for a prestigious music competition, all from the Music Studies program—except for Kahoko. With Lili's magical violin in hand, Kahoko is urged to join the competition. In 'Kiniro no Corda: Primo Passo,' we follow Kahoko's journey with Lili as she delves into the world of classical music, facing the challenges of the contest and competing against her peers in this new musical realm.
