The story starts out with Kiyohiko "Piyohiko" Saketome trying to take a band audition. In his way he sees a strange man named Jaguar carrying a big case, which turns out to be holding only a small recorder. Piyohiko tries not to get distracted by him but fails, because when Jaguar plays his recorder, the most beautiful, passionate guitar-like sound comes out of it. After that, Piyohiko gets accepted at a record company and finds out that he is now dorm roommates with Jaguar. Jaguar becomes a teacher and sets up a recorder class at their music school, and Piyohiko ends up in that class instead of the guitar class he wanted.
