Limbo: Border Jail

Limbo: Border Jail is a technique which uses the power of the Rinnegan.

Usage
The user projects a shadow of themselves into the invisible world known as. The shadow is generally impossible to detect or visually perceive without the Rinnegan. This can operate independently of the user and attack or restrain target(s), or defend the original body from attacks as the shadow was strong enough to repel all nine tailed beasts in a single instance. All the while to the naked eye, it appears to be the act of an invisible force. However, Naruto Uzumaki gained the ability to sense its presence after receiving the chakra of all nine tailed beasts and half of the Sage of the Six Paths' power while Sasuke, with the other half, is able to see the clone perfectly with his rinnegan.

Drawbacks
Although it is invulnerable to most physical attacks, techniques which make use of the Sage of the Six Paths' chakra can cause harm to the shadow. The downside to this technique is that the user's shadow, after a set period of time, automatically returns to their body and it is left temporarily unusable.
