Naraku appears before Sesshomaru and offers him a human arm embedded with a Sacred Jewel shard. Armed with this, Sesshomaru attacks Inuyasha and takes Tetsusaiga, unleashing its full power to slay a hundred demons at once. As Miroku's Wind Tunnel is sealed by poison insects, Kagome fires a sacred arrow that restores the sword to Inuyasha.

Back in the modern world, Kagome finds herself unable to return to the past. Inuyasha had destroyed the well to keep her out of harm's way. Meanwhile, the group investigates Naraku's past and learns of a bandit named Onigumo—who may hold the key to the mystery connecting Naraku and Kikyo.
