On her fifteenth birthday, Kagome Higurashi's life abruptly changes when a demon yanks her into the ancient well of her family's shrine. Transported back to a time when yokai roamed freely across feudal Japan, she is relentlessly pursued by these malevolent beings, all craving the mysterious item she unknowingly bears: the Shikon Jewel, a tiny orb of immense power. In this perilous situation, she meets a half-demon youth named Inuyasha, who initially confuses her with Kikyou, the shrine maiden he harbors ill feelings toward. Because of her resemblance to Kikyou, Inuyasha harbors a fierce dislike for Kagome. Yet, recognizing the peril they both face, he abandons his resentment and offers her aid. During a clash over the Shikon Jewel, the sacred gem shatters into fragments that disperse across the realm. Fearing catastrophic fallout, Kagome and Inuyasha embark on a daunting journey to retrieve the shards before they land in hostile hands. Their bond strengthens as they confront ancient foes and uncover secrets that bind their destinies together.
