List below are the fighting styles that exist in the Psyomaster Ryuken universe along with their known users.

Nishin Kongou Genma (Dual God Diamond Phantasm)
An elusive technique practised by only the most able and worthy of Shurokiu, the origins of this style are mostly unknown. The most apparant facts is that is definately an extention of the Shurokiu's awareness of ESP within them.
Whatever the originations, the style properly founded 5000 years ago was nevertheless preserved and nursed for it to be used as a shadowry crime-fighting syndicate for the governments of the Shurokiu and has since become their most powerful weapon on the forces of evil.
Nishin Kongou Genma works twofolds through the channeling of the users self induced mental powers. It firstly toughens the muscles and physical attributes allowing an extrordinary amount of super strength. It secondly allows the physical manifestation of their psychic powers to be used for a range of attacks and techniques ranging from energy blasts to the paranormal abilities that ESP has long been known for.
A first and most important aspect before anything else however is for the user to go through rigorous training to adapt the body into the right conditions to use the above. Psychic powers are dangerous to use as they are benificial for it is possible to overdose and die on such energy.
Additionally whilst any practitioner may be taught the general basics, they may also specilize in the harnessing in certain natural elements such as fire and water, and can have a 100% control in how they behave too.
For each branch only one new member can be initiated once every few years though there's no real limit to how many is allowed into the order even if their numbers are not in the thousands. Those who succeed as a successor earn the title Soryu shinsei (twin dragonrebirth) and may pass the style onto other successors. The fighting force and organisation of this style are known as the Soryu Youkai (Twin dragon apparition)
Known practioners of Nishin Kongou Genma: Ryu, Maud, Shogun.


Nishin Kongou Hogasha ken (Dual God Diamond Guardian Fist)
A pale variation of Nishin Kongou Genma, the guardian fist is an enforcer placed to protect the Soryu shinsei's if needbe. Unlike its superior, this style focuses psychic energy into the body only, increasing strength and defence dramatically. In attack Nishin Kongou Hogasha ken uses a lot of grappling and wrestling moves to take down an adversary although fighting styles vary.
Known practioners of Nishin Kongou Hogasha ken: Dloplla

Mt Shyva Earth Splitter
Originates from mount Shiva. Has the power to draw energy from vibrations in the ground. This technique uses on an array of energy blasts, powerful punches and fiery kicks.
Known practioners of Mt Shyva Earth Splitter: Kul

Byakko Gunryo Ken (White Tiger War fist)
As the Shurokiu have Nishin Genma, there are those amongst the race of Sphinx Nekos that have also developed a good few killing technique of their own, in particular the Byakko style. This martial art is supposedly an inheritance from Byakko heavens above, whom the angels used in the pre-creation war against the forces of evil. Whether this is true is impossible to tell. Never the less there is a feel to this style that is unearthly, and has capabilities that can be considered either god-like or demonic.
The inner clockworks of how the style works varies with the many branches that are out there, but although Byakko Gunryo ken is intended to be on the side of good, the essence of this style is usually to generate vast spiritual ki energy through an unusual harking towards dark intent, as if to know the rules of war and go with the flow. Some of the more powerful branches like Hogasha ken, can be described only as Hellish. The user may use sheer controlled anger to wreak terrible bloodthirsty havoc onto any adversary that may get in their way. Some survivors with whatever sanity left over after enduring such a describe these masters as the devil themselves and even the several practitioners of this martial art are convinced they are possessed by a demon. As part of the final stages of training there are even some sorts of branches like Hogasha ken that allow the young padewans to go on a rampage on whatever unfortunate criminal force there is as as last lesson in controlling their powers. Those who survive this trial and also give in to the bizarre trance that may be induced are called Gunryo no Makai; dark magicians of the destructive unconscious powers.
The feats that the style pulls off in the field are again varied but the most common trends tend to be the manifestation of Ki into feline shaped projectiles and\or super strength and speed. Some of the branches even turn the users positive psychic energies to negative, similar to the undead, meaning Psyomaster's are unable to read the Byakko demon's mind or feel his presence.
Also worth noting that whilst Nishin Genma is limited to Ryuken's dimension and world, Byakko Gunryu ken is reported to transcend time, space and even alternate dimensions. Successors or even training grounds for this style are very rare though, almost myth-like. Practioner TST claims that he's the first in over 500 years to have learnt the branch that is Byakko Hogasha Ken. He even claims that he was told that Byakko Gunryo ken was born along with the beginnings of the universe, hence with the Gunryu essense running in his blood he was able to defeat an "immortal" adversary with 2 million years more age and experience than him.
The race of Sphinx Nekos with Byakko Gunryu Ken do not kneel before the Shurokiu and their Nishin Genma and whilst no outright war or mass bloodshed has taken place between the two races, the rivalry over which martial art is the strongest continues to this day.
