A boxer without a prayer meets a naïve nun who might be his only chance for salvationâ ¦ and victory in the ring. Times are tough at Mukaida's Gym. Though a promising novice with a surprise win in his debut bout, Kosaku has since adopted a steady regimen of extremely unhealthy eating habits—enough to make his coach ready to permanently throw in the towel. Will Sister Angela's teachings help Kosaku realize that the road to victory is not paved with bowls of ramen? Or will Kosaku's burgeoning feelings for the young nun undermine his ability to concentrate on training, fighting and binge eating?

Four years ago, Kosaku pulled off an astounding upset in his pro test by KO'ing a big-time boxer. More than simply sending his opponent down for the count, Kosaku also managed to mangle this pretty-boy fighter's teeth in the process. Now this toothless tyrant is ready for a rematch, but can Kosaku drop down an entire weight class to qualify for the bout? It is said that the weight of a fighter's punch comes down to how hard he grips his fist, but will Kosaku ever get a grip on his pre-fight snacking?
