History's Most Stubborn and Knucklehead-ed Warrior

A warrior is someone who specializes in combat and warfare. But, what does a warrior fight for when all he's known is in the past? Naruto has found himself in a strange land after fighting Sasuke at the Valley of the End and has been lost in more ways than one. Now, he's found a path to walk down once more. Not as a shinobi, but as a martial artist. Don't flinch, dattebayo!
