Barrier: Impure World Reflection

This technique creates a barrier that masks the presence of those inside of it by making their chakra unable to be sensed and rendering them invisible by bending the light around them. However this does not prevent those inside from using jutsu. Unlike many other barriers it is almost impossible to see and the only way to identify it is by finding the black lines that mark the boundries.

In order to perform this technique the user must be in possession of all four of the Rashinban Tanken. Each of the four blades are embedded into the ground to mark the boundry of the barrier. To activate the barrier the user must use a technique specific seal. After activating the barrier, a black line forms on the ground that marks the boundry. The barrier will then remain in place so long as the activater is alive, does not cancel it or when 24 hours pass.

Trivia

 * The origin of this technique is unknown, though it has been implied to have come from the time of the Sage of the Six Paths.
 * Since Sanger possesses all four of the Rashinban Tanken, only he is capable of creating this barrier.
