Kagome is an ordinary modern schoolgirl living an ordinary life. Who would have thought the dried-up old well on the site of her family's shrine would be a gateway to Japan's ancient past? Drawn through the gate against her will, Kagome finds herself battling demons for control of what she thought was a worthless trinket but is actually a powerful magical gem, the Shikon Jewel! Together with an unlikely ally, the half demon Inuyasha, Kagome begins a quest to recover the shards of the Shikon Jewel and learn more about her link to the past.

With the power granted by a large piece of the Shikon Jewel, Naraku's scheming is in high gear as his minions go forth to do his bidding. Kikyo, the priestess whose duty it once was to guard the jewel, gave the fragment to him, but why? Then Inuyasha takes on another of Naraku's evil offspring, a demon that inhabits the very sword his half brother Sesshomaru wields. Naraku's human origins may yet prove to be his downfall if Kikyo can exploit his weaknesses by forcing him to make a difficult choice, one that is mirrored by Inuyasha's lost love for Kikyo and a possible future with Kagome!
