Clan Name: Reiki Clan
Age of Clan: Exact age is unknown, estimated to have existed for over 2000 years
Special Characteristics: This Clan is as tangible as the wind. Its members, whenever they show up, act swiftly and quietly, dissapearing as soon as their mission is done.
The members of the Reiki Clan can control their ''Aura'', which is an energy similar to Chakra. The different types of Aura can be distinguished by their color. Different Shinobi have a different Aura, so there may be several Shinobi with a blue Aura and several with a green one, etc.
Village: None. The Reiki Clan is pretty much a village in itself but it doesn't have enough members to count as a village.
Location: Due to the lack of knowledge, it can only be assumed that the Reiki Clan is either always on the move, or located at a secret place which can only be accessed by its members.
Hierarchy Structure: There isn't a leader, yet there is a group of veteran Shinobi, who have mastered their Aura well and make the general decisions in the Clan. They are called the Reiki Jonin. Then there are the Shinobi who are still learning but are already quite skilled and can apply their Aura in a variety of situations, the Reiki Chunin. The ''newbies'', who are skilled in the normal Shinobi way (taijutsu, ninjutsu, genjutsu) but haven't mastered their Aura and the Kekkei Genkai yet, are called Reiki Genin. The Reiki Chunin and Reiki Genin have a say in Clan matters as well, yet the big decisions and strategies are left to the Reiki Jonin Council.
Kekkei Genkai: Reiki Hari
This Kekkei Genkai takes a lot of time to be mastered. When used, it puts the user in a state in which he can use his Aura. Depending on the type of Aura the user has, he is engulfed in flames of that particular color.
Let's say the user has a silver Aura. After activating the Kekkei Genkai, he would then have silver flames emanating from his body. These flames would not hurt him, of course. He can then summon the flames to for example his hand. By thrusting his hand outwards, the amount of Aura concentrated in that particular area would be unleashed, hurting opponents or objects in its way.
The user can also use Aura for a variaty of other uses, most of which depend on the type of Aura. The use of Aura can also be done without the Kekkei Genkai, but it takes a lot more energy and it's not nearly as strong that way.
Special Kekkei Genkai Techniques:
Aura Style: Energy Tremor
(Aura is summoned to the user's hands. The user then punches the earth with his hands, which results in the Aura exploding around the user, hurting everything in a certain radius.)
Aura Style: Burning Senbon
(Aura is shaped into millions of small needles which are let loose at the same time. They fly in a straight line, able to pierce a human's skin to the bone.)
Aura Style: Barrage
(The user summons Aura to his legs and arms, boosting his taijutsu moves with extra speed and strength. As soon as the opponent is brought into contact with Aura, he will be knocked backwards and, depending on the type of Aura and the amount of it, hurt or even slightly burned.)
Note: These are basic Techniques, the uses vary from Aura type to Aura type.
Bio/History: Many years ago, the Reiki Clan seemed to just pop out of nowhere, with powerful members and a fearsome Kekkei Genkai. Who founded the village and who created the Kekkei Genkai is a mystery. The Reiki vanished as soon as the appeared, leaving people to question their existence but whenever there was a large war or a similar distaster, the Reiki appeared again, sometimes fighting, sometimes just watching. From time to time, villagers would run away from their village and join the Clan but they how and why is a mystery.
Blue: A common Aura type. Allows the user to sharpen their Aura and cut through many weapons, even jutsu or other Kekkei Genkai.
Green: Not very common. With this type of Aura, the user can manipulate small animals and opponent's (weak) clones. Using the Kekkei Genkai, the user can form their green Aura into thin objects like whips or even a vine that wraps around the opponent.
Red: Uncommon. This type is very strong and it can burn the opponent on contact. With the help of the Kekkei Genkai, the user can cause large explosions or fires using their Aura.
Silver: Uncommon. A strong Aura type, which is at the same time a sensory type. The user can close his eyes and use the Aura to detect any living beings in a certain radius. With the Kekkei Genkai the user can use his Aura to increase his speed tremendously.
There are many more and these paragraphs only slightly touch the many powers and uses of Aura. The nature of Aura depends on the personality and chakra of the user. Not every Shinobi can master his/her Aura, so it is rumored that the Clan picks the Ninja who can control their Aura.
