La Corda d'Oro
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 into the competition...until now.
Kahoko is a normal student in the General Education department with absolutely no musical skill, but all that changes when she catches a glimpse of an elusive fairy who lives on campus. The fairy grants Kahoko a magic violin, and before she knows it, she's nominated to participate in the school's music competition with five very attractive boys.
Will she win love and fame, or will bitter rivalry rule the day?
