When the power is used, you can take a stack of black shurikens and throw them at the opponent. Then, it all disappears. It will appear on the first object, enemy, wall, etc. straight in front of where you threw it. It will flash red and then explode. All this happens in one or two seconds, depending on the distance. You can throw a deadly multitude of shurikens at the foe, covering their entire body before throwing the last one into the head, causing the opponent to fall and explode.
