Plot
Kikyo was tricked by a demon who posed as a young child lost in the forest. The following day Kagome gets angry at Inuyasha because he refused eating her cooking food then she used sit and storms off on a "walk." While out, she senses a jewel shard and follows the sense to same cave. She heard the child's cry as she apporached and entered on her own. She finds Kikyo, on the verge of death (because she'd nearly exhausted all her souls). Inuyasha was waiting for Kagome to come back. Kagome and Kikyo were still trapped in the cave which was actually a demon that lured priestesses in and drained them of their power. Kagome remembers when Kikyo and Inuyasha are kissed in front of her who was under Kikyo's spell and talking about Inuyasha's temper. Soon they encountered demons, but Kagome successfully fought them off. They came to the central core of cave Kikyo revealed to her that was the demon's heart. Kagome fired an arrow but nothing happened, her spiritual power having weakened withing the cave. Kikyo begged her to escape on her own, but Kagome refused to leave Kikyo behind. Back at camp, Inuyasha stopped waiting and searched for her. Kagome combined a jewel shard to the arrow, with no effect. Kagome gave the remaining shards to Kikyo, who uses their combined power to fuse the shard together. With the new shard, Kagome successfully kills the demon, which dissolved in light. Standing in a meadow where the demon was, Kagome recovers the shards while Kikyo's Soul Collectors come to aid her recovery. Kikyo asked Kagome why she never gave up on her and Kagome explains that "someone we both know would be heartbroken" if Kikyo died. As Kagome leaves, Kikyo mused that it would be same had Kagome died. Kagome finds Inuyasha and they return to camp holding hands.
