Iwamaki Rikitarou is a free man. Heís got no ties or obligations to hold him down, nothing to stop him from determining his own way of life, and thatís the way he likes it. ExceptÖ his girlfriend wants to break up with him, his bandmates donít respect him, and with no accomplishments to his name, heís 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.

Meanwhile, Oishi Raita has pitched a reality tv show to a studio, which will chronicle the trials of boxing amateurs as he trains them up to challenge the pro test. The studio snaps up the idea, all they need now are some interesting amateurs to drive the first season.

The premise of the manga [[ForegoneConclusion promises that their lives will intersect]], but itíll take a twist of fate, as well as some personal tragedy, to see it come to fruition.

!! This series provides examples of:
* ALadyOnEachArm: Ren.
* AffablyEvil: From Iwamaki's brief conversation with him, [[spoiler:Asahina Ren]] seemed like a pretty cool guy to hang with, albeit completely reckless and a shameless playboy, but that all changes in Chapter 87, when he [[spoiler: verbally confirmed that he's the one responsible for the death of Rikitarou's sister and the fact that he has no remorse for doing so]].
