Here he comes, two swords a'swinging. Miyamoto Musashi is the guy we are talking about. He pisses off his dad, wipes out the male line of a family and then adopts a son to make up for the other adopted son who had to kill himself because culture of the time and stuff. He managed to write a few books ("The Five Rings" not a prequel to "The Lord of the Rings" as John thought) and become the greatest sword fighter ever (don't have much knowledge of who to compare it to so we will just do the "World Champion" thing for lack of contenders). Enjoy post-Hallows Eve fun!
