Tsubaki

is a dark shrine maiden who made a deal with a demon and sold her soul to retain her youth and beauty. In her youth, she was Kikyo's rival and sees her chance at revenge when she encounters Kagome Higurashi. She met her end when Naraku lured her to do his bidding with the almost complete Shikon no Tama and she underestimated Kagome's abilities.

She first comes in on Chapter 193: Kuro Miko Tsubaki. Here first appearance in the anime is Episode 60 and I believes go's too episode 64.
