14 years after the decisive Battle of Sekigahara, that virtually established the Tokugawa Shogunate's hegemony over all of Japan under the shogun Ieyasu. But vestiges of the old order remain in the form of a final resistance by the Toyotomi clan. Entering the fray on the Toyotomi side is a soldier revered and respected by many as the kind of hero who only appears once in a hundred years: Yukimura Sanada. But all isn't as it seems. Despite his manly appearance and reputation, Sanada owes his rise to glory to a miraculous string of good fortune and is actually a coward. Fortunately, Sanada encounters a former ninja named Sasuke Sarutobi, who has fled his ninja roots in hopes of staking his place in history. Sasuke sets about bridging the gap between perception and reality for Sanada by concocting a brilliant plan of deception. He recruits 9 misfits and gives birth to the Sanada Ten Braves who get to work turning Sanada into the greatest general in the land.
