This article takes Ninjutsu too seriously. Its fucking fake. Get over it. Some guy claimed to be taught by some nomad like figure is the basis for this entire school of martial arts that isnt even EFFECTIVE is real combat. When was the last time a Ninja won  a NO RULES tournament? With the fluke win exception of UFC 4 i cant remember any. Also you dicks going to ninja schools should learn a real martial art like Brazilian Jujitsu.
