A boxer without a prayer meets a naive nun who might be his only chance for salvation... and victory in the ring. 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?
