The Inuyasha group tracks down someone who's been using Miroku's identity.

Inuaysha and the others find a demon using a fake Sacred Jewel and, with the help of a scholar, search to find out how, and why.

With his friends imprisoned, body and soul, inside the toad demon's slime to be sacrificed for the making of a second Sacred Jewel, Inuyasha must face off against a half-demon powered up by a dozen fake jewels alone.

Jaken is poisoned and it's up to Rin to find a cure for him before it's too late.
