Aside from the five basic types of nature transformation, there is also a sixth type: the Yin (陰, In), the basis of imagination and spiritual energy, used to perform Yin Release (陰遁, Inton); and the Yang (陽, Yō), the basis of vitality and physical energy, used to perform Yang Release (陽遁, Yōton). Together, they are used to perform Yin–Yang Release (陰陽遁, Onmyōton). Yamato implied that the Yin and Yang are the source of non-elemental jutsu such as the Shadow Imitation Technique, Multi-Size Technique, medical ninjutsu, genjutsu, etc.
