Episode 167

 is the one hundred sixty-seventh and final episode of InuYasha.

Summary
Sesshomaru begins to leave, Kagura reveals that she knows where Naraku hides his heart. She gives a crystal shard to Jaken so they can detect the gem protecting Naraku's heart.

InuYasha, Miroku, Sango and Kagome leave the temple. They find a cave filled with the remains of demons and a strong demonic aura.

Hakudoshi meets Kagura, and brings her to the temple. Hakudoshi and Goryomaru engage in battle, Goryomaru is surprised to find his light has no effect on Hakudoshi and is wounded.

InuYasha smells the blood and he and his companions race back to the temple to attack Hakudoshi. Hakudoshi rushes in and slays Goryomaru. Kanna and the infant appear; Hakudoshi takes them away, leaving Kagura to deal with InuYasha. Kagura tells InuYasha that the infant carries Naraku's heart, then follows Hakudoshi.

Miroku helps the children bury Goryomaru and tells them they must leave.

Kagura follows Hakudoshi to a stone demon. She turns back to lead InuYasha and his friends to the stone demon.

InuYasha and Kagome head into the stone demon's stomach where they sense Naraku. Kirara carries Miroku, Shippo and Sango down to join InuYasha. Naraku pulls out the almost complete Shikon Jewel. The stone demon comes to life, and Naraku gloats over the fact that they will all be digested by the demon and leave the jewel shard behind. Miroku tries using his Wind Tunnel, but when he starts absorbing saimyosho InuYasha stops him. InuYasha tries using his Adamant Barrage, which tears apart Naraku but does not harm the stomach of the demon. Kagome tries to purify the Shikon Jewel with an arrow, but Naraku disappears.

Kikyo comes across Kanna and the infant and realizes that it is Naraku's heart. As she draws her bow to shoot the infant, the giant demon Hakudoshi left to guard attacks Kikyo and Kanna escapes.

InuYasha uses Kagome's jewel shard to make Tetsusaiga stronger, but the shard becomes corrupted and begins to overcome InuYasha, allowing his full demon form to come out. When Kagome rushes forward to hold InuYasha the jewel shard is purified again and InuYasha regains control. He uses the Tetsusaiga with the jewel shard power boost to tear open the stomach of the demon, destroying the demon and allowing them to escape. As they see daylight again, Kagome passes out.

Sesshomaru, Rin and Jaken arrive at Goryomaru's temple, to find it empty, and a recently dug grave has been dug up and stands open and empty.

Back in Kaede's village, Kagome and Miroku are healing. InuYasha and Kagome talk, Kagome tells InuYasha she has been glad to be there with him. Silently, InuYasha feels the same about Kagome.
