Orphaned before he was ten years old, Musashi (his real name is Takezo, so you'll hear his childhood friends call him by that name) grows up skilled in the martial arts. During the Battle of Sekigahara, he fights on the side of the losing Toyotomi forces, but eludes the enemy as they hunt down the vanquished soldiers. He then spends years wandering the countryside mastering the sword, becoming a stronger samurai. As his fame spreads throughout the nation, men seek him out to test their skills against him--most notably Sasaki Kojiro who faces Musashi in the ultimate Duel at Ganryujima.
