Also known as La Corda d'Oro (the golden string), Kin'iro no Corda is an Otome Game with a manga and anime adaptation. The anime adaptation gives a face to the nameless protagonist in the form of Hino Kahoko, an ordinary high school student who was given a magical violin by Lily, the spirit of the school.
Every few years, the prestigious Seisou Academy holds a prominent musical competition, and only the very best students at the Academy are allowed to participate. Though all are eligible to apply, only students from the music department actually make it to the competition... until now.
The series proved succesful and spawned various sequels: the first two ones feature Kahoko, but Kiniro no Corda 3 takes place 8 years after the first game's timeline, featuring a new protagonist joining Seisou High School: Kanade Kohinata, as well as a new set of guys (but with the old ones doing cameos) The latter one has been greenlighted for an anime series.
