Used by the Sage of Six Paths, Hagoromo Otsutsuki, to create the tailed beasts in Naruto, Yin-Yang Release is a type of nature transformation that merges Yin and Yang Release. As these two styles of ninjutsu exist beyond the realm of the five basic elemental natures, Yin-Yang Release is a unique type of transformation that very few in the world of Naruto can perform, with techniques themselves being so advanced that these individuals have come to be revered as gods.
