Kyojitsu

Kyojitsu (虚実, "Art of Truth and Falsehood") is a unique style of Ninshū that puts emphasis upon the mastery of Yin Release. It is the signature art used by Keiji Katsura, whom is renowned as its founder, and is the reason for earning the title "Katsura of the Yin Release".

Yin is the deciding factor in all material things. Without it, energy expands and loses form; loses its truth as it is rendered onto something that can only be imagined if not sensed. Its existence can not be seen, for whatever form you believe you see, it is an illusion masking what exists past its beautiful image. After all, Yang expanded and created the entirety of the heavens; the skies above us that are mere illusions masking the outer spacial regions that lie beyond. But Yin gave birth to the Earth, a material world of substance; of truth that can be proven and witnessed. Kyojitsu is an art that ties together heaven and earth. Real motions, such as physical attacks, can be rendered mere illusions, passing through Katsura's body as though they do not exist. On the other hand, falsehoods can become reality by imbuing them with the Yin energies necessary to grant the formless mass of energy a true form. In particular, Genjutsu cast by Katsura can become real.
