Japanese schoolgirl Kagome is pulled into a well by a centipede monster and through a 500-year time tunnel to Japan's civil-war era. She escapes from the well with Inu Yasha, a half-dog demon imprisoned in the well 50 years earlier by the priestess Kikyo. The local villagers believe Kagome to be the reincarnation of Kikyo, and she must reluctantly team up with her predecessor's enemy to hunt down the many shards of the "Jewel of Four Souls," which Inu Yasha originally came to steal.
