Naraku calls upon a priestess named Tsubaki. Fifty years ago, Tsubaki was defeated by Kikyo when she went after the Shikon Jewel. She is a dark priestess who sold her soul to a demon to maintain her youth and is now after Kagome's blood.
Tsubaki visits the onmyoji mansion where she once trained. She plans to open a forbidden door in order to train an ogre that was sealed away in the pagoda with the power of the Shikon Jewel. Momiji and Botan, two young priestesses, are tricked by Tsubaki into fighting off Inuyasha and the others.
Tsubaki is a priestess who was considered to be on par with Kikyo. She was jealous that the Shikon Jewel was not entrusted to her, so she became a dark priestess. Inuyasha and the others defeat Tsubaki's shikigami, but Tsubaki has already broken the forbidden seal and called forth the demon.

A demon born from a piece of flesh that Naraku discarded transforms into a man without a face and steals the handsome face of Muso, a traveling monk. The demon calls himself Muso and slaughters and plunders along his way to Kaede's village.
Muso regenerates even thought he was hit with the Wind Scar. Miroku tells Inuyasha that Muso has a heart in the area where he has a spider marking. But Kagura interferes, and the hell wasps take away Muso's shard.
Inuyasha visits Totosai in search of a technique that can break through Naraku's barrier. There he meets Bunza, a wildcat-demon child. The two do as Totosai orders them. Bunza acts as if he's the older disciple, but ends up collapsing.
Myoga comes to deliver a message from Totosai. He says that the Tetsusaiga will become stronger if it cuts a Hyakki Bat, a demon that can create a powerful barrier. Inuyasha and the gang search for the Hyakki Bats' nest, which is near the sea.
The Hyakki Bat demon Otakemaru tries to destroy the village along with Shiori's mother. Inuyasha is blocked by Shiori's barrier and cannot defeat Otakemaru. Shizu asks Otakemaru to respect the will of her late husband, Tsukuyomaru, and save the village.

The Tetsusaiga is equipped with a technique that can break through barriers. Jaken plans to steal it from Inuyasha, but his plans continually fail. Rin is disgusted. Jaken chases her away and lures Inuyasha to a hot spring, and manages to steal the Tetsusaiga.
Naraku tells Sesshomaru that he'll give Rin back if he kills Inuyasha, but Sesshomaru charges into Naraku's castle instead. Meanwhile, Kagome detects the presence of the Shikon Jewel. Inuyasha leaves Kagome and the others to find the shard, while he looks for Naraku's castle by himself.
Naraku is trying to absorb Sesshomaru so that he can get the powers of a complete demon. But Inuyasha breaks through his barrier and interferes. When Naraku sees that the tables have been turned, he retreats behind his miasma.
