InuYasha, full title InuYasha, a Feudal Fairy Tale, is a Japanese manga series written and illustrated by Rumiko Takahashi. The story centers on a time-traveling middle school student, a half-demon, a lecherous monk, a fox demon, a demon slayer, and a nekomata during the Sengoku period who seek to find all the fragments of the Jewel of Four Souls (Shikon no Tama) and to keep them out of the hands of evildoers, especially Naraku. The manga was adapted into a 167 episode anime series produced by Sunrise. InuYasha premiered on Yomiuri TV in Japan on 16 October 2000 and ran until 13 September 2004. The television run of the anime ceased without a conclusion to the story.
