Ishikame

Ishikame (石亀, Ishigame; literally "Turtle", referencing their camouflage) is a technique used by Shinigami.

Overview
It is a technique that allows one to move so swiftly that they leave behind a distinct afterimage of their person behind so as to trick an opponent into thinking they have not moved from their original position. The image itself cannot move as it fades through everything that moves toward it. In most cases, it is used to dodge an incoming attack and get behind the opponent to perform a counterattack, but it isn't limited to just that as it can also be used to confuse enemies. It can be used to distract the enemy, giving the user a chance to perform the actual attack.
