A disgraceful practice, ninjutsu is the art of using specialized weapons created specifically for use by the deadly assassins and shadow warriors known as ninja. No honorable warrior would ever humiliate himself and his ancestors by demonstrating knowledge of such a shameful nature, and indeed many samurai, when confronted with the bizarre implements of the ninja, have difficulty fathoming their use altogether, other than as crude and relatively ineffective weapons.
