Silent Killing

This technique is unique to Kirigakure shinobi. As the name suggests, this technique is simply a very quiet method of killing an opponent, usually from behind with a blade. Additionally, because the user moves silently, the attack cannot be anticipated and defended against. The user will often slit their opponent's throat, preventing any cry that might give them away. The Seven Ninja Swordsmen of the Mist are shown to be masters of this technique, and were even good enough to track and kill opponents through sound alone. Some shinobi also opt to use a cover such as mist or even frost to rob their opponents of their field of vision and then attack them.
