Yura

Sakasagami no Yura was a hair demon, as well as the first demon to appear as a serious threat to Inuyasha. Yura resided in an invisible cocoon made up entirely of hair while hiding her true form in a red comb, which she hid in a skull. She was at least fifty years old before the Shikon jewel returned to the Sengoku period in Kagome. Yura manipulated the townspeople of Kaede's village via her hair so that Inuyasha would succumb and she would obtain his shikon jewel shards. During their fight, while she had Inuyasha cornered, Kagome was wearing his fire rat robe and was thus protected from Yura's razor-sharp hair. After Kagome found Yura's true form, the comb hidden away in a red skull, she grabbed one of her arrows and smashed it into the skull breaking the comb and causing Yura to wither away to dust. While Yura was relatively short-lived, she nevertheless had the distinct honor of being the first strong opponent that Inuyasha and Kagome faced together.
