Inuyasha and his companions come upon an orphan named Koharu, a young woman who believes she is in love with Miroku, after he helped her three years ago. When Koharu needs help again, they assist her and find her a home in a new village. When Naraku sends Kagura and Kanna to destroy Inuyasha and his companions, Koharu and the villagers become the new pawns in Naraku's devious plan.

Inuyasha and his group must defend themselves against an attack on multiple fronts. Kanna attacks Kagome, attempting to suck her soul into her mirror while Sango remains unconscious in the same room. Koharu tries to stab Miroku, while Inuyasha battles Kagura. Can Inuyasha use his Wind Scar to defeat her?

Inuyasha, though still recovering from his serious wounds, fights Goshinki, a demon who is eating an entire village.

Sesshomaru goes to a swordsmith, Kaijinbo, to get a new sword made from the fangs of the demon that broke Tetsusaiga, Goshinki. But something unexpected happens, and Kaijinbo attacks Inuyasha on the night of the new moon, when Inuyasha reverts to his human form.
