The award-winning manga of one young man's journey to become the greatest saxophone player in the world. Dai lived a normal high school life in Sendai: a city of hot summer days and rainy nights. Between basketball, part time jobs, and an uncertain future, something was missing. And that thing was music. With his days in senior year running out, Dai swears a heartfelt vow: 'I'm gonna be the best jazz player in the world'. But what do you need to be the best? Talent? Effort? A lucky break? Or maybe just a deep, pure love for music, and too much stubbornness to know when to quit.
