Shinobi Sect: Sage's Will Materialization

Derived from the teachings of Ninshū, which is a style exemplified best when energies are united to form something incredible, in order to teach mortals that they must learn to understand and rely on one another; the only way the world will understand peace. However, these teachings were perverted by Seireitou through this technique, most likely due to being Kaguya Ōtsutsuki's transmigrant, becoming a technique that actually does the exact opposite of its intended purpose.

Using his Byakugan, which allows him to perceive even the flow of energy that composes the world around him (thus being able to read the flow of natural energy), it becomes possible to materialize his will onto all natural energy, allowing him to connect his internal chakra with the natural energy in the atmosphere, turning it into his very own energy. By doing so, he enters into a pseudo form of Sage Mode in which he utilizes senjutsu without actually making it enter his body; as the energy in the space around him is itself a part of him.

It goes without saying that through this technique, it becomes impossible for Seireitou's opponents to draw upon natural energy simply because his will has dominated the energy flow which his Byakugan allowed him to perceive, granting him information normal opponents would be incapable of attaining. However, even if they managed to perceive the same things he could, the energy is already subdued under his will and has become a part of him. While it is possible for them to attempt wrestling command over the natural energy in the atmosphere around them from Seireitou's grasp, however unlikely it is, the latter would simply not afford the opponent the necessary time and concentration needed to wrestle away something that is under the will of a man that has himself forged his will like a blade: strong and unyielding.
