Suddenly arms emerge from the dark well and Kagome is dragged down into it. She finds herself face to face with a giant centipede woman who keeps mentioning a jewel. Kagome shoves her away causing her one of her arms to tear off in the process, much to Kagome's bewilderment. When she exits the well she finds that she is standing in a forest. Soon she notices a strange boy pinned to a tree with an arrow through his chest. Eventually Kagome makes her way to a nearby village where she meets an old woman named Kaede.

Everyone in the village, including Kaede is shocked by how much Kagome resembles her deceased sister Kikyo. Kagome discovers that she has travelled through time to feudal Japan and that the boy she saw pinned to the tree is Inu-Yasha, a half demon that was once in love with Kikyo, but Inu-Yasha betrayed her, and tried to steal the Shikon Jewel, a mystical jewel that grants demons immense powers. Inu-Yasha had killed Kikyo and the Shikon Jewel was cremated with her body. Eventually Mistress Centipede comes looking for Kagome again and manages to seperate her from the rest of the villagers who are trying to protect her. Mistress Centipede tears at Kagome's side and amazingly the Shikon Jewel pops out. Mistress Centipede swallows the Jewel and begins to transform. Kagome's only choice is to free Inu-Yasha in hopes he will save her.

Inu-Yasha makes quick work of killing Mistress Centipede and retrieving the jewel for himself. Kaede and Kagome manage to stop him with a necklace that forces him to the ground when Kagome yells "Sit!" though. Soon other demons arrive trying to claim the jewel and in the process it is shattered with pieces spreading across Japan. As Inu-Yasha and Kagome travel in seach of the jewels they meet Shippo, an orphened kitsune, Miroku, a lecherous monk with a curse on his hand, and Sango, a demon exterminator who's family was murdered. Soon they find that Kikyo has been brought back to life and then, ultimately, it is discovered that Inu-Yasha and she were lovers who were tricked into believing they each betrayed one another by Naraku, a creature who is responsible for Miroku's curse, Sango's family's death, and Inu-Yasha's loss of Kikyo. Now it's a race to see who can collect the shards first and use the reunited Shikon Jewel for the ultimate good or the darkest evil.
