Iaidō (居合道) is a samurai-skill where the user quickly draws the blade to strike, then re-sheaths it after every attack. The speed of the user is so fast that it prevents enemy shinobi from forming hand seals (thus ninjutsuninjutsu), making it highly effective against ninja. Mifune is a master of this style, making him highly effective against ninja even of Hanzō's calibre.
