Types

Reiku
A technique based on one's spiritual energy which can be uniquely specialized depending on one's genetics and  the environment in which an individual was raised in. Reiku evolves from one's cells and can be the fundamental energy of every living being on earth or the entire universe. Even embodying the desires and the will of those who master its techniques. A person is capable of utilizing all the basis of Reiku, known as a divergent or specialist. One's affinity for certain Reiku abilities stems from how one has trained their Reiku in there respective environment. For example, if someone was raised around wildlife for a large portion of their life, they may be subject to learning specific elements of Reiku more naturally then those who live in a normal environment for those who can utilize Reiku at will. However, not all beings are capable of using it at will. In some instances, there must be certain environmental conditions required for their Reiku to be used, though divergent users don't have this issue. Reiku is vital for survival but most beings cannot freely control their aura ,  but many who can manipulate it also have learned to control the flow of aura   within their bodies allowing them to channel larger or smaller amounts of their aura   reserves. In essence they can adjust their strength to match the situation by gaining perfect control over one's Reiku   as it is channeled, thus stopping any of it from leaking out of their body as an individual is shown to become exponentially more powerful. Certain individuals can also develop new abilities or as a response to harsh new environments, instantly create adaptations that allow the user to survive. Training one's Aura to adapt to a variety of such environments is an integral part of the training.

Usage
By focusing their aura, an individual can manipulate Reiku and use it outside of their body. Reiku can be used in many different techniques. There are physical limits to the strength of the body itself, but it's necessary to increase one's aura to overcome this barrier and become stronger. It can be used to sense people's spiritual energy by using one's aura as a sensor to feel the pressure of another user Reiku. These are the components of Reiku.
 * Coating:  Allows the user to use their Reiku as armor as defense against attacks, as well as make their attacks more potent. A person can apply the aura to a section of their body, over their entire body, and even apply it to their weapons. While the durability of one's flesh and bones carry an obvious limit, the extent of a Reiku user's Aura does not carry these limits. As a result, Reiku users can increase their endurance by raising their Aura usage to deflect other aura attacks, Raising one's Aura to guard can be used to block attacks even more powerful than the other user, although this can be extremely dangerous and often fatal. Advanced users can focus on outputting a larger amount of aura than normal, projecting it outwards explosively albeit at the cost of expending said aura, the user's emotion's and intentions can change the shape and the color of their Coating Aura which will amplify one's strength, the advance users can send a pressure force to other users capable of causing nosebleeds, nausea, pushing them violently, or even knocking them into a coma-like state incapacitating them. It is seen to be strong enough to defeat individuals with weaker Aura or not strong enough to handle the pressure of the stronger user's Reiku. Immensely strong Reiku Users can cause harm to their surroundings creating a rare and natural phenomenon that consists of extreme storms and an untouchable vortex of aura that gets formed in the clouds which shake the environment where these users stand.
 * Reiku Pressure Sensory:  A user with enough Reiku control eventually learns how to sense it, being able to sense the location and amount of aura in certain points, insinuating that the stronger and closer the enemy the more powerful the sensation. Also, if the source of aura is very powerful, it can be sensed from afar by people who are trained to sense the pressure caused by one's aura. Advanced users gain a sixth sense of the world around them and limited precognitive abilities while also creating abilities that utilize the aura in their eyes. This transfers a specific amount of Aura to both the eyes themselves, which have several passive abilities special to the user.
 * Zen Mode:  The user can conceal, suppress or otherwise prevent their aura or the auras of others from being sensed and/or recognized. Allowing them to conceal their presence, emotions, alignment, health, power levels, personality, etc from others. Advanced users can make themselves unnoticed and/or ignored by their surroundings and entities and be disregarded by threats or dangers. Some users can even use Zen on their abilities infusing objects (usually a weapon), beings or powers with invisibility.

Reiku Typing
Reiku Typing : Also known as Tiers of Aura. Individuals who develop Aura are placed in a bracket or a separate class of Reiku users depending on the type of Reiku one possesses. All Reiku users are similar in the usage of the ability, but the type of Aura they conjure can be immensely different depending on the user. These classes go off of the colors one can display and the amount. Most Reiku users can generate a normal colorless aura that will not only display outside of the user body, but inside as well as forming around the cells, muscles, and bones of the user. Special users can change the color of their aura or they can inherit the color of their aura. Each color can possess a different trait and have a unique meaning for the user. This method of classifying Aura types is the same as discovering someone's zodiac sign.
 * Colors Of Honoring:  A type of Aura that is used by anyone that holds no evil intentions. The appearance of this type of Reiku is usually a white or blue aura around the user. The personality of those with this class of aura is normally users who care a lot about others and what they think of themselves, and their way of helping people is through actions not words. They're extroverted, idealistic, charismatic, outspoken, highly principled and ethical, and usually know how to connect with others no matter their background or personality. Mainly relying on intuition and feelings, they tend to live in their imagination rather than in the real world. Instead of focusing on living in the “now” and what is currently happening. They tend to be influential without even trying. Their influence stems from their authenticity and altruism, and people around them don’t question their motivations. They are loyal, reliable, and genuinely kind for no other reason than wanting something better for themselves and others. The user can empathize with any kind of animal while advance users can control strong-willed creatures with ease. The user can also empathize with the surrounding ecosystem making it easier for the user to adapt to most environments quickly. This class of Aura can produce a fair amount of Aura without further training, but can eventually reach great amounts after mastery.
 * Colors Of Warriors  ( Man At Arms):  A type of Aura that is used by true Warriors/Fighters. The appearance of this type of Reiku is usually Red, Orange, Violet, Pink, or Green. These users have an ideal to fight for the true meaning of life. They believe that finding a purpose in the whole scheme of things is more important than material possessions. Due to their extroversion, idealism, and charisma, these users become humanitarians, artists, coaches, and leaders. They are visionaries and idealists who ooze creative imagination and brilliant ideas. They have a different and usually more profound way of looking at the world. They have a substance and depth in the way they think, never taking anything at surface level or accepting things the way they are. Others may sometimes perceive them as weird or amusing because of their different outlook on life. They're caring, complex, and highly intuitive individuals. Artistic and creative, they live in a world of hidden meanings and possibilities. While they place great importance in order, they can also be spontaneous because they intuitively understand things without being able to pinpoint why. These users can activate and utilize powers based on emotions and also use their aura to sense pain, disease and etc, from others and themselves. These users are more prone to awaken the hidden potential that has slept within them easier than other users. This type of user can generate large amounts of aura with no strain and tend to have greater physical aspects.
 * Colors Of Kings:  A type of Aura that is used by users that are the embodiment of Emperors, Conquers and Kings. The appearance of this type of Reiku is usually Gold, Black, and Platinum. These types are introverted, quiet, reserved, and comfortable being alone. They are usually self-sufficient and would rather work alone than in a group. Socializing drains an introvert’s energy, causing them the need to recharge. They are interested in ideas and theories. When observing the world they are always questioning why things happen the way they do. They excel at developing plans and strategies and do not like uncertainty. The Intuitive and thinking traits form the core of the user's personality type, making them highly intelligent, open-minded and utilitarian individuals capable of amazing intellectual feats. People with this personality type tend to firmly believe that they are intelligent and capable of many things. Their quick and versatile minds allow them to enjoy intellectual challenges and they'll feel bored when they're not intellectually stimulated. These types are ambitious, self-confident, deliberate, long-range thinkers. People with this aura and personality type are ruthless when it comes to analyzing the usefulness of methods, ideas or others in general, while some other types would happily accept the argument that things have always been done in this way. This typing would question and challenge the existing procedures. This makes them efficient and impartial decision-makers, often at a very young age.

Keosu Abilities & Typing
Keosu:  Otherwise known as   Chaos abilities, they are the embodiment of one's desire through their Reiku. Its qualities are influential, but not restricted to the user's natural Reiku Classification (Aura Typing). Keosu is highly versatile, having offensive, defensive, and useful supplementary applications. It can be emitted directly from the body to manifest semi-solid weapons and instruments or real-life items that serve a unique purpose solely for the wishes of the user. This is the outcome of Reiku mastery and the key technique for giving Reiku users the upper hand in many different situations. The more creative the user's imagination is the more versatile the ability will become. Abilities can also be approved upon as time goes on so that the user can gain better control over the ability and seek it's true purpose or just create another desired ability. Keosu abilities are also split into typing to make them easier to understand the process and type of aura one needs to create the abilities. These classes consist of 3 forms of typing.
 * Zōen : The ability to use aura to modify the natural abilities of an object or one's own body. Examples of more complex superhuman abilities include enhancing one's Reiku to take the form of different objects but not becoming the object completely. This is executed by directly accessing the user's physical and mental energies, relying on the stamina and strength gained through training. It typically requires little aura, but has a great impact on the ability. Aura can also be infused directly into particular body parts, increasing their strength and even generating beneficial mutations like transformation into other beings or creatures. This is the right typing for those that want to save their time and Reiku, or for those who rely on their physical attributes. It can also be used uniquely in collaboration with other types of keosu.
 * Henkō : The affinity for Henkō means a person can transform their aura into other elements or use their aura to directly control real-world elements at will. This allows the user to mimic the properties of a substance or element with their Reiku, Henkō   is not limited to copying the properties of solid matter. They can even become a solid matter of different properties. It can also be "Advanced", attaining the ability to use their aura in different manners than they originally could. Henkō users come in a variety of forms which can be divided further into several subcategories. With such a broad range of available powers, it is difficult to generalize the abilities offered by the Henkō class. How to trigger the Henkō type power can also differ from user to user as most users rely on changing the properties of their aura into something they're familiar with and adapted it into extreme conditions. With practice and experience, certain elements can become second nature to a user and be used at will almost like they are one with the element.
 * Hōyō : In most cases, Hōyō is intended as the ability to create physical and independent items and/or weapons out of one's Aura. Once a person has mastered the materialization of a certain object, they can create it and dispel it whenever they want instantaneously. Each object in this class has it's own subcategory. Objects that are solely for combat are known as "Spirit Beast" or "Spirit Weapons" and those objects that are used to manipulate other beings are called "Sōjū" abilities. Belonging to the Sōjū class allows the user to control living or non-living things, including aura constructions. Sōjū is a user who can pour the most aura into an object strengthening an object more than any other class. The complexity of the orders assigned also depends on the target.
