ninja

They were masters of Ninjutsu(The Art Of Stealth) the martial art of the ninja NOT Kung Fu. For those who can't tell the difference between samurais and ninjas a Samurai is more like a soldier without guns but armed with Swords,Bows and arrows But Ninjas or Shinobi is more like a guerrilla squad using Swords, Shuriken, Smoke Bombs, etc. Everything that people believe in like how ninjas can do anything like run on water, make some hand seal and turn in to smoke and how people think ninjas are demons that kill people for no reason were wrong. The science of ninjas were higher and that's why they thought Ninjas were Magicians but they were only illusionist who fooled the eyes of the ignorant. Even the military uses the ninjas tactics and weapons like smoke grenades originally came from smoke bomb. Samurai described ninjas from there experience from battles then later people made up stories like how a ninja summoned a Giant Frog to Defeat it. Later on Masashi Kishimoto created Naruto the anime cartoon episodes as seen in cartoon network based on Japanese folk stories. Ninjutsu contained Pressure points, Samurai Sword Techniques, Chinese Philosophies,Meditation,etc. The code of the ninja(Ninpo) which was was against the code of the samurai (Bushido). The art of the Samurai was death. But the art of the ninja was to survive, get the job done and escape. This gave ninjas greater advantage. They also borrowed stealth tactics from Sun Tzu the Chinese general.
