The final season of the anime series InuYasha aired in Japan on Animax from December 8, 2003 through September 13, 2004. It is produced and broadcast in high definition, while maintaining its standard 4:3 aspect ratio. Based on the manga series of the same title by Rumiko Takahashi, the anime was produced by Sunrise. The series follows a high school girl, Kagome Higurashi who travels back in time to the Sengoku period of Japan where she meets a half-demon named Inuyasha and learns that she is the reincarnation of a powerful priestess named Kikyō. Joined by a lecherous monk, a young kitsune, a demon slayer, and a demon cat, the group seeks to find the fragments of the shattered Jewel of Four Souls, a powerful jewel that had been hidden inside Kagome's body, and keep the shards from being used for evil, including the evil half-demon Naraku who slew Kikyō fifty years before Kagome's arrival.
