In Piova, the city known for music and endless rain, young men and women gather to pursue their dreams of becoming musicians.
Chris Vertin is one of those young men. He leaves his rural hometown and his girlfriend, Arietta, behind to enroll in the Piova Communal School of Music―the town landmark. Arietta's younger twin sister Tortinita is also a student here.
Winter has come, and it has been over two years since Chris moved to this town with the goal of becoming a “Fortenist”―a master of the magical instrument known as the Fortelle.
