its a gag manga that's been on for a while now (since 2000). Its about a story which starts out with Kiyohiko 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. Kiyohiko 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. He tries more and more record companies, but every time he meets Jaguar and somehow manages to miss his audition. Finally, Piyohiko gets accepted at a record company only to find at his new dorm that he is 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…
