At the age of 27, Rikitaro's aspiration to become a rock star akin to Jimi Hendrix or Jim Morrison is dwindling. Meanwhile, Ooishi, a retired three-time world boxing champion, now spends his days shooting a boxing reality show. These two seemingly dissimilar individuals cross paths one day, giving it no second thought until weeks later. Rikitaro is offered a last chance by a record label to sign a deal, but the catch is that he needs to improve his physical health to be more marketable. He serendipitously stumbles upon a boxing gym, where coincidentally, Ooishi is filming his show. As destiny takes its course, neither man realizes that they will come together to train the best boxer the world has ever seen, surpassing even the great Ooishi himself.
