Shugendo

"Yeah, that's right, humans can only unleash their latent power to get stronger, so what now?... well, i'll tell you one thing. Even if i told you the name of this... technique of mine, it wouldn't matter, because this is the last thing you're going to see before you meet those in the next world. But for simplification purposes, you can just as easily refer to this as a Super Human!"

- Rasetsu Reveals Shugendo

Shugendo(修験者, Lit. "Path of Power Resulting Ascendancy") is a "technique" that requires extensive knowledge or extreme talent in harnessing and using the ethereal force of Yin-Yang Essence within ones Ki. The ability was invented by Rasetsu as his counterweight against opponents that are capable of transforming. It is a testament to the tenacity and unpredictability of the human races warriors, being aptly nicknamed "The Legendary Super Human" transformation by those who have witnessed it first hand.

Overview
Through the limitless creative abilities granted by Yin-yang essence, Rasetsu was ability to force out his dormant, latent energy and stabilize it with Yin. As such, the transformation is primarily based on the building blocks of yin while yang is less prevalent, serving to hold the body in its ascended state through its endless physical energy generation and vitality. Performing this action caused this transformation to be born in Rasetsu's body, increasing his power level, strength, speed, reaction time, and durability far, FAR beyond their original limitations. Essentially, it is a stabilized version of his latent energy kept in control and at the surface. The transformation is succeeded only by The Chouetsu Shugendo form which was developed by Rasetsu also.

Usage & Power
Due to being the "embodment" of martial arts philosophy, the transform is different from most other ascended forms displayed by other races. Instead of focusing on the multiplication of power, or the augmentation of strength, speed, and durability, The users power is directly dictated by their current emotional state. This is due to the fact that Yin-yaing essence is directly influenced and effected by ones current state of mind, and as such, the power is not dictated by what the user achieves in the form, but rather, "what the user desires". The effects and powers of this state, particularly the energy, strength, and physical attributes will rise in the direction of the users emotional state. As such, a user who may be weak willed is not capable of effectively wielding the Shugendo transformation, but a person whom is focused and has achieved a state of wholeness within their mind body and soul may be able to unleash potentially endless amounts of benefit and power boosts.
