In'yō

In'yō (陰陽 lit. Yin and Yang) is a mysterious Kekkei Genkai; rumored to be one of the most complex of such bloodline traits known. It's passing is similar to the Rinnegan, though it isn't as rare because of intricate complexities that very few can fully understand without lectures. The In'yō's complexities begin with its manifestation; its powers vary from person to person depending on the time they were born. Supposedly, there are only 12 users of this trait at one time.

Overview
The In'yō's power lies within that of the Chinese Zodiac, and the power over Wu Xing that stems from it. The Chinese Zodiac involves 12 animal signs and generally one born under the sign has personality traits as described by it. These zodiac signs are the Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Ram, Monkey, Rooster, Dog, and Pig. These zodiac are each fixed to one of the 5 elements of Wu Xing, and what sign a user of In'yō falls under is based on what hour they fall into; which are:

23:00 – 01:00: 子 rat (Yang, 1st Trine, Fixed Element Water) 01:00 – 03:00: 丑 ox (Yin, 2nd Trine, Fixed Element Water) 03:00 – 05:00: 寅 tiger (Yang, 3rd Trine, Fixed Element Wood) 05:00 – 07:00: 卯 rabbit (Yin, 4th Trine, Fixed Element Wood) 07:00 – 09:00: 辰 dragon (Yang, 1st Trine, Fixed Element Wood) 09:00 – 11:00: 巳 snake (Yin, 2nd Trine, Fixed Element Fire) 11:00 – 13:00: 午 horse (Yang, 3rd Trine, Fixed Element Fire) 13:00 – 15:00: 未 ram (Yin, 4th Trine, Fixed Element Fire) 15:00 – 17:00: 申 monkey (Yang, 1st Trine, Fixed Element Metal) 17:00 – 19:00: 酉 rooster (Yin, 2nd Trine, Fixed Element Metal) 19:00 – 21:00: 戌 dog (Yang, 3rd Trine, Fixed Element Metal) 21:00 – 23:00: 亥 pig (Yin, 4th Trine, Fixed Element Water)

As stated above, there are 5 elements within Wu Xing, and these are wood, fire, earth, metal, and water. Wu Xing is described as the cycle of Creation and Destruction; the relationships are as follows:


 * Wood feeds Fire
 * Fire creates Earth (ash)
 * Earth bears Metal
 * Metal carries Water (as in a bucket or tap, or water condenses on metal)
 * Water nourishes Wood
 * Wood absorbs Water
 * Water rusts Metal
 * Metal breaks up Earth
 * Earth smothers Fire
 * Fire burns Wood
 * Wood parts Earth (such as roots; or, Trees can prevent soil erosion)
 * Earth absorbs (or muddies) Water (or Earth dam control the water)
 * Water quenches Fire
 * Fire melts Metal
 * Metal chops Wood

In Wu Xing, each element is affiliated with various things including mental quality, emotions, organs, body parts, senses, and even an aspect of life; along with manipulation of that element completely, the In'yō grants control of these aspects as well. In tune with the Chinese system of Feng Shui, certain things within the world, when within the area a user is in, will help augment their power. Wu Xing, being a concept of creation and destruction, allows a user to generate or augment their through other elements (as long as they are not overcomes by that particular element; see above), as well as destroy the elements of their two elements they can overcome and their various affilitions. Wu Xing isn't just destruction though, it is also creation, and In'yō also has healing and other supportive abilities. Along with this ability, being tied to the Chinese Zodiac, whose various signs are affiliated a certain direction of wind, an In'yō user naturally will also have an affinity towards wind release, and can call upon their specific wind to help with many troubles.

Trivia

 * The In'yō is known as such; meaning Yin and Yang, because the 12 signs are split in six between Yin and Yang; a universal distinction.
