In addition to being the leader of ROCK DOWN, Shou is also a world-renowned violinist. While doing promotional activities with the others for VAZZROCK Live, Shou spends his free time practicing for his own upcoming solo violin concert. One day, Shou heads to a rehearsal studio and Haruto follows along, asking if he can listen. When the two reach the studio, Shou is unexpectedly reunited with Kodai Ejima, a violinist who performed with Shou in an American orchestra in the past. Ejima adores Shou's playing and wishes Shou would devote himself to classical music again. However, when Shou invites Ejima to his solo concert, Ejima declines.
