Iwamaki Rikitarou is a free man. He’s got no ties or obligations to hold him down, nothing to stop him from determining his own way of life, and that’s the way he likes it. Except… his girlfriend wants to break up with him, his bandmates don’t respect him, and with no accomplishments to his name, he’s just hit twenty seven, the age at which several of his musical idols died, and also the age at which Oishi Raita, the Japanese international boxing champion, has just announced his retirement. Feeling the pressure to make something of himself, Rikitarou decides to muster up his commitment and go professional with his band.
