Yoshotoshi Heion was a 1st year high school student who had no desire to excel–and liked it that way. In fact he chose Hiyotani High school for that reason. It was an average school only 5 minutes from his house. There's even a cute girl in his class, Rina Fujimoto, and he's already given up on her. But Rina wants to join the "Wind Orchestra Club" (Brass Band Club) only to learn it's been disbanded. Rina's passion for music inspires Yoshotoshi to help revive the club. "Once you make the first step… Who knows what will happen?"
