An incredibly simple technique that allows the user to fire a single burst of chakra from their fingertip that possesses a penetration similar to an arrow. Like all techniques under the Phantom Arts discipline, this technique is invisible to the unaided eye and is ideal for assassination. Unfortunately due to this, this technique is incredibly difficult to aim without supplemental sensory abilities. While being classed as an assassination skill, this technique would require nearly perfect accuracy to kill outright, similar to a kunai. While this technique could easily pierce an opponents flesh, from a long distance it would likely refract off of bone. In addition, it has shown a mild concussion effect on a wooden wall, damaging a design inscribed on it.
