Season 4

The fourth season of the anime series InuYasha aired in Japan on Animax from August 19, 2002 through May 12, 2003. It is the first season of the series to be 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 Kikyo. 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 Kikyo fifty years before Kagome's arrival. The first season introduces the central characters and shows the group gathering together.

The anime is licensed for release in North America by Viz Media. The English dub of the fourth season was broadcast on Cartoon Network as part of its Adult Swim programming block from January 18, 2005 through July 23, 2005.
