Towa Higurashi

Towa Higurashi is the main protagonist in Yashahime: Princess Half-Demon. She is Sesshoumaru's first daughter and Setsuna's older twin sister. She was somehow transported to the modern era through the power of the Tree of Ages and the Bone Eater's Well when she was just four-years-old. She received shelter from her uncle's in-laws, the Higurashi family, and was subsequently raised by her half-uncle-in-law, Souta Higurashi. She is reunited with her sister Setsuna after spending ten years in modern times. She wields the weapon Kikujuumonji.
