CHIN's

Sango, a demon slayer, is invited to Hitomi Castle along with her father, the leader of the demon slayers, and her younger brother, Kohaku. But it is a trap. Meanwhile, the undefended village is attacked by a horde of demons and annihilated. Naraku takes the Shikon Jewel shards that they had been gathering and leaves.

Kikyo paralyzes Kagome. Inuyasha appears before her. Kikyo has been gathering the souls of dead girls. She vents her grudge against Inuyasha. Inuyasha reveals that he has never forgotten her. When Inuyasha kisses Kikyo, Kikyo tries to drag him to hell. But Inuyasha hears Kagome's voice and regains consciousness.

Kikyo, who was brought back to life, is living as a priestess. A monk, who realizes that Kikyo is dead, tries to make Kikyo pass on, but Kikyo ends up killing him. Inuyasha saves the monk's disciples and runs to Kikyo when he hears the priestess's name.

Kagome returns to the shrine in the middle of her date with Hojo. She senses the presence of the Shikon Jewel shards and returns to feudal Japan. Naraku reveals that fifty years ago, Onigumo was in love with Kikyo. The demons that were drawn to Onigumo by his malice devoured Onigumo, and the demon Naraku was born.

Kagome has her sacred jewel shards taken away from her and is returned to the present day, unable to return to feudal Japan. Back to her normal life, she agrees to go on a date with Hojo. Meanwhile, Inuyasha and the gang try to find out more about the mysterious Naraku.

Sesshomaru wields the Tetsusaiga with his borrowed arm against Inuyasha, who fights back with his scabbard. When the two strike each other at the same time, Inuyasha gets up close to Sesshomaru, rips off his arm, and gets back the Tetsusaiga. When Inuyasha learns Naraku's plan, he fears that Kagome might die.

Naraku appears before Sesshomaru and lends him an arm with a sacred jewel shard embedded in it. Sesshomaru attaches the arm to himself and appears before Inuyasha and the gang to steal the Tetsusaiga.

Kagome is able to pull out the Tetsusaiga. Sesshomaru tries to kill her, and Inuyasha is angered and fights to protect Kagome. His will to protect a human changes the Tetsusaiga into its true form, a fang sword.

The muonna makes Inuyasha reveal the location of his father's grave. Sesshomaru removes Inuyasha's right eye (the black pearl) and opens the entrance to the grave. Kagome is angered by Sesshomaru's cruelty. She goes with Inuyasha after Sesshomaru. Inside their father's tomb is a memento of Inuyasha's father, the sword Tetsusaiga.

Kagome learns that Inuyasha is a half demon, born of a human mother and a dog demon. Inuyasha's half brother Sesshomaru appears, looking for the tomb of their father. In order to manipulate Inuyasha, he brings Inuyasha's dead human mother with him. But the woman turns out to be a demon known as a muonna.
