Yura

Yura of the Hair (Sakasagami no Yōma Yūra 逆髪の妖魔 結羅) is a minor character in Inuyasha. She is the first demon to appear as a serious threat to Inuyasha. She makes her first appearance in the manga in Chapter 6 and episode 4 of the anime

Biography
Yura was one of the first demons to give Inuyasha and Kagome Higurashi the fight of their lives. Residing in an invisible coocoon made up entirely of hair while hiding her true form in a red skull, Yura manipulated the townspeople via her hair so that Inuyasha may succumb and she may obtain their Shikon shards.

During their fight, while she had Inuyasha cornered, Kagome was wearing his fire rat robe, and was thus protected from her razor-sharp hair. After she found her true form, a comb hidden away in a red skull, Kagome grabbed one of her arrows and smashed it until Yura was no more.

While Yura of the Hair was relatively short-lived, she had the distinct honor of being the first true tough battle for Inuyasha.

Yura's Outfit
Unlike most of the demons who appeared in the series thus far, Yura was by far the most human-like, taking the apperance of a young girl wearing traditional kunoichi (female ninja) garb.

Yura wears a dark and revealing ninja tunic which is cutoff midway at her thighs, and sleeveless.
 * Kunoichi Tunic

Yura wears a bright yellow sash which ties at the front of her outfit.
 * Yellow Sash

Yura wears thin, tight and dark arm guard on both of her hands which is holstered by her middle finger and extends beyond her wrists. They are more decorative in nature, than serving as actual "guards", as per most ninja wore at the time.
 * Arm Guard

Yura wears thin, tight and dark leg/foot guards on both of her legs which start midway from her shins down to her middle toes, held by thin straps at her arches. Leaving her practically barefoot, they are more decorative in nature, than serving as actual "guards", as per most ninja wore at the time.
 * In-Step Guards

Weapons
Yura's trademark weapon are her razor-sharp strands of her which are apparently capable of cutting through anything except Inuyasha's kimono, which was woven from the hair of the fire rat. She is also able to control people as puppets via her hair.

During close-range combat, Yura uses a wakizashi (a Japanese short-sword) she calls "Crimson Mist" during combat.
