Synopsis

 * 1) Sesshōmaru rejects Kagura's offer to kill Naraku, much to her fury.
 * 2) Kagome and the others speculate that Naraku must be a hanyō like Inuyasha, which would explain why his powers have weakened.
 * 3) For an instant, Kagura sees Inuyasha in his human form; Kagura surmises that Inuyasha's time of weakness is on the night of the new moon, though she chooses to keep this bit of information from Naraku.
 * 4) Naraku, still in his powerless state, reprimands Kagura for leaving the castle, saying that this will be her last chance, another incident like this and he will force her to return to his flesh once again; Kagura learns that Naraku is a hanyō as well and that his body is made up of many yōkai.

Summary
Sesshōmaru turns down Kagura's offer, being uninterested in the Sacred Jewel, and tells her to use the Jewel Shards herself if she wishes to kill Naraku. Enraged, she flees further away from the castle. Inuyasha and his friends, with Kōga, follow her. With the knowledge that Naraku's barrier is weakening, Inuyasha's gang realize that Naraku, who is half-demon, loses his power at the new moon just like Inuyasha.

Kōga battles Kagura again, but gets beaten again, and is nearly killed. Inuyasha intervenes just in time to save him, as the dawn breaks. However, for a split second, Kagura sees Inuyasha in his human form, and realizes his weakness. Inuyasha uses Wind Scar on Kagura, but a horde of Naraku's demons jump in front of her and are destroyed, during which Kagura escapes. Koga recovers his two Jewel Shards.

Kagura returns to the castle, thinking that Naraku knows nothing of her betrayal, but he has seen everything in Kanna's mirror. Kagura follows Kanna to Naraku's basement and is pulled underground by an otherwise-powerless Naraku, discovering his weakness and that he is also half-demon. Naraku gives Kagura one last chance to remain at his side, threatening to absorb her back into his flesh if she betrays him again. Kagura decides to keep Inuyasha's human form a secret from Naraku, deciding to use him as her trump card.
