The rouran is an ancient clan said to be descendant from royalty.
Rouran female warriors posses long, thick heads of hair; thanks to the special way the hair is looked after as well as the special way that ki is channeled into it, its as strong and pliable as a dragon's whisker. Every strand of their hair has greater tensile strength, modulus of elasticity, and sheer resistance than an iron wire of the same thickness (average hair diameter: .045 inches).
Rouran female warriors possess the psychokinetic ability to animate their hair for a number of feats, including elongating it to almost twice its normal length (the average length is approximately 6 feet (1.8 m) in length when relaxed), and using their hair to lift and move heavy weights; a portion of their hair must be used to anchor the rest at these greater weights, so that more than their scalp/skull is used as a brace.
They can control the movement of their hair as if it were countless thin appendages growing from their head.
ki permeates the hair-cells, causing mutual attraction across the gaps between strands. These relatively small forces operate in conjunction to develop larger forces. Through concentration, the kounichi can move their hair in any manner imaginable. They can snap the length of it through the air like a whip (the tip of which moves faster than the speed of sound), or rotate it in a fan-like manner. They can bind persons or objects with it as if it were rope, or use it to lift objects which weigh more than they could lift with their arms. (The scalp, skull, and neck do not support the weight of an object that they lift: It is held aloft by the ki coursing through the hair.) They can also perform delicate manipulations with their hair such as lock picking or threading a needle, and such complex acts of coordination as typing or shuffling a deck of cards. However such intricate feats require years of training. Although they have no nerve endings in their hair, they can "feel" sensations on all parts of their hair by a form of mental feedback from their chakra.
They are also able to retain some degree of control over her hair after it has been cut or otherwise severed from her scalp. Each rouran woman at the time of her death leaves behind a single strand of dragon’s hair. Thousands of those strands are woven together to make a whip.
Dance of the Red Sparrow
The warrior shoots a barrage of hair needles at the opponent each hair is as stiff as steal. This technique is strong enough to pierce through rock
Because so much ki is channeled through the hair less of it flows through the body and muscles, making female warriors a lot weaker then the average human.
======This Rouran Dancing Whip:
==Edit======Males of the rouran clans are given the rouran dance whip. It's an extension of a Rouran warrior’s own soul; it's a gift woven from "Dragon Hairs", each strand left by a Rouran woman at her death woven together to form a braid as strong and flexible as a dragon's whisker. It contains the life force of the lives of the Rouran women used to make it! This whip is impossible to destroy because of all of the life force used to protect it. The whip itself consists of a single grip in the middle with two whip lengths protruding from each side.
The Rouran Dance Whip Style:
A rouran dance whip is a very powerful weapon requiring its wielders to be very quick, strong and quiet. The Rouran Dance Whip Style focuses on quick and fluid attacks coupled with evasive agility. In general, The Rouran Dance Whip Style focuses on fast combos. The style usually uses the whip to grab opponents and spin their body to the point that they die through a massive amount of pressure, force, and twisting. Most importantly, however, is its range of mobility. As the rouran males can perform throws from a distance and incorporate jumping into their attacks better than any other fighter.
