Inevitable Barrier

By using his Yang Release for a small moment Sigma is able to create a barrier around himself that allows him to absorb the chakra of others if it's hit. Additionally, one who has the Yin Release, can literally remove the physical properties of a technique, making the attempted technique nothing. After a technique is absorb, Sigma will be able to fire the exact same technique back towards his foe, as well as add the absorb chakra into his own supply.

This technique basically acts as a chakra absorbing barrier. Against Reikoku this technique proved to have no flaws other than how long he's able to hold it. Ultimately being labeled as a "god" like technique.
