Episode 32

Kikyo and Inuyasha, Into the Miasma  is 32nd episode of Inuyasha

Plot
Upon hearing that a priestess skilled in the arts of healing is nearby, the followers of the sick lord Kagewaki go to seek Kikyo and bring her to the castle. There, Naraku, who borrowed Kagewaki's flesh, is astonished to see her "alive", and try to keep her captive. She frees herself without much effort.

Meanwhile, Inuyasha and his friends go to find the source of the recent rains of blood and demon's body part which are frightening the villagers. They find the source of the miasma to be in a mountain. Sango, still frail, must stay outside due to the poison, with Kagome and Shippo, while Inuyasha, Kirara and Miroku go inside, where they find demons fighting, with evidence that hundreds of them found their death here. Inuyasha is drawn into the battle, much to Miroku's worry, for he recognized a spell made to merge the demons into ever more ferocious ones. Naraku indeed intends to usurp the body of the last survivor.

Kikyo goes into the cave, too, passing in front of Kagome without so much as acknowledging her. But near the demons, the dead souls which keep her alive begin leaving her body. Inuyasha, enraged, fight even more ferociously, while Kagome and Sango find the force to join Miroku at the entrance of the cave of the battle. Kagome goes to rescue Kikyo, so that Inuyasha won't put himself in danger for her. Kikyo contemptuously rejects her offer, and breaks to merging spell. This causes the merging of all the demons' flesh into Naraku, reforming his body, without Inuyasha, the last demon fighter.

In the ensuing confusion, Inuyasha and his friends regain safety, but Kikyo herself is taken by a Naraku surprised that she broke the spell instead of killing the demon with whom he merged, as she could have done. The episode ends with Kikyo awakening in his arms as she is taken away from Inuyasha.
