Kagome Higurashi's 15th birthday takes a sudden turn when she is forcefully pulled by a demon into the old well of her family's shrine. Brought to the past, when demons were a common sight in feudal Japan, Kagome finds herself persistently hunted by these vile creatures, all yearning for an item she unknowingly carries: the Shikon Jewel, a small sphere holding extraordinary power. Amid such a predicament, Kagome encounters a half-demon boy named Inuyasha who mistakes her for Kikyou, a shrine maiden he seems to resent. Because of her resemblance to Kikyou, Inuyasha takes a violent dislike to Kagome. However, after realizing the dire circumstances they are both in, he sets aside his hostility and lends her a hand. Unfortunately, during a fight for the Shikon Jewel, the miraculous object ends up shattered into pieces and scattered across the land. Fearing the disastrous consequences of this accident, Kagome and Inuyasha set out on a challenging quest to recover the shards before they fall into the wrong hands. [Written by MAL Rewrite]
