Decomposition Armour

It is a technique based on Yin-Yang Release: Decomposition Barrier. In this technique, Alvaro covers himself with a layer of this barrier, a thin layer that covers his entire body, giving him immunity against ninjutsu as it decomposes chakra into yin and yang, getting rid of any nature transformation and mixing them once more to create pure, harmless chakra. It gets rid of senjutsu as well. Then, the chakra goes directly to Alvaro. While using this technique he can't use ninjutsu however, he is immune to any type of ninjutsu.
