The story begins in Feudal Japan, when the half-demon InuYasha steals the Jewel of Four Souls—a magical jewel that enhances the power of and can grant a single wish to the one who wields it—from a village. InuYasha desires the gem in order to turn himself into a full blooded demon. InuYasha does not get far before Kikyo, the young miko of the village, shoots him with a sacred arrow that indefinitely seals him onto Goshinboku, a sacred tree in the nearby forest. After being mortally wounded, Kikyo tells her younger sister, Kaede, to burn the jewel with her body to prevent it from falling into the hands of evil.
In modern Tokyo, a junior high school girl named Kagome Higurashi is on her way to school. She stops in the well house of her family's Shinto shrine to retrieve her cat, Buyo, when a centipede demon emerges from the well and pulls her into the Sengoku period of Japan.
