Kagome Higurashi's ordinary life comes to an abrupt halt when a demon drags her deep into a well, transporting her five hundred years into the past. In this era, Kagome quickly learns two things: demons walk amongst humans and she has unknowingly brought a dangerous object from her world—a marble-sized sphere known as the Shikon Jewel. This unusual orb brings tremendous power to any demon who has it in their possession, and Kagome is an easy target for anyone determined enough to steal it.
While in a fight with a demon, a hasty attempt to fend it off causes Kagome to accidentally shatter the jewel, sending countless pieces of it all over feudal Japan. She soon learns the grave consequences of her actions when she must work with the half-demon Inuyasha to collect all the pieces of the jewel before they fall into the wrong hands.
