犬夜叉 - Season 5 (2003)

Kagome is a modern high school girl who doesn't believe in the old myths and legends surrounding her grandfather's shrine. That is, until the day she falls into the shrine's well and into another time! In Japan's ancient past, Kagome joins the half demon Inuyasha on a quest to find the scattered shards of the Shikon Jewel, a gem so powerful that demons from across the land will do anything to get even a piece. Along the way they gain friends, battle enemies, and prepare to face their deadliest foe and rival for the Shikon Jewel--Naraku!
