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. Sister Angela hopes her teachings will help Kosaku see the error of his misguided ways. But 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?
There's a new face around Mukaida's gym--a wannabe teenage pugilist who'll do anything to prove he's got what it takes to be a fighter... So why is he always sucker punching coach Mukaida? Can Kosaku bounce back from a bout with food poisoning in time to correct this young tough's bad attitude? Later, Kosaku strikes a bargain with Sister Angela. If he wins his next big eight-round fight, she'll agree to spend Christmas with him. Sounds simple enough, so why is the Mother Abbess forbidding Kosaku from punching his opponent's midsection? Could it have something to do with the Mexican fighter's religious tattoo?
Final Volume!While Kosaku's eternal struggle with his weight wages on, a meddling aunt tricks Sister Angela into paying a visit to her family, but is this all just a ruse to set the lovely sister up with an eligible young chef? Later, Kosaku's dedication is put to the ultimate test when he's given the option of pursuing a career in the restaurant business and retiring from the world of pugilism for good. And finally, Sister Angela's aunt outdoes herself by racking up an exorbitant bill at a host club and leaving her niece holding the bag. Kosaku vows to defend Angela's honor by challenging the dashing host to a title match, but will Angela defy the Mother Abbess and break her curfew to be at Kosaku's side? It's time for the final round to begin!
