The Bond Between Them, Use the Sacred Jewel Shard! (Part 1) is the one hundred sixty-sixth episode of the InuYasha anime.
Inuyasha, Kagome, Miroku and Sango hear from local villagers that the mountain demon was killed by bright shafts of light a few nights ago. When they arrive at the remains of the giant demon, Inuyasha smells humans nearby.
In a village, a demon is attacking. Three children defeat it, and cart away the remains. They take the remains to a temple.
Inuyasha and his friends hear of these ascetics that are slaying demons, and head off to find them. While they take a break, the children appear and attack. Inuyasha defeats them and the children run off.
Inuyasha and friends follow the children to their temple. The monk, Goryomaru, comes out, and has a demonic arm. When hoards of demons attack, Inuyasha, Sango and Miroku assist Goryomaru in defending the temple.
Miroku and Goryomaru talk and the children admit they cannot tell good demons from bad. The monk offers them shelter for the night.
Kagura takes command of the demons that have gathered around the temple. She sends them in to attack, and Miroku, Sango and Inuyasha come out to battle. They see that the attacking demons are already dead. Miroku uses his Wind Tunnel, until the arrival of some Saimyōshō.
Kagura thinks the infant is hidden within the temple. Inuyasha heads after Kagura, demanding to know why she is attacking the temple.
Kagura soon realizes the infant is not in the temple, and after receiving a serious wound she retreats. She falls from her feather near Sesshomaru, Jaken and Rin. Rin wades into the river to help Kagura. Jaken tries to help and is swept along as well. Sesshomaru pulls all three from the river. As they watch, Kagura regenerates and awakens.
Meanwhile, Hakudoshi stands with Naraku in their mountain base. He inquires why Naraku lets Kagura live, since both of them know full well that she is a traitor. Naraku summons Kagura's heart in his right hand, and points out that he could crush it if he wished, but he won't. When asked why, Naraku replies that she will make the perfect bait for leading Inuyasha into a trap. He then declares that he has a task for Hakudoshi.
