Inuyasha and Naroku have battle on numerous occasions and multiple episodes.
That is episode 100.
well at the end of the final episode inuyasha and his friends were captured inside of a demons belly and it was filled with miasm so anyway inuyasha and naraku started fighting inuyasha started to become weak so he used the jewel shards on his sword to get strong and then he killed naraku
Inyuash defeats naraku in the last season The final chapter.
To free her brother from naraku
Episode 66 - Naraku's barrier, Kagura's decision .
When the reancarnation of Naraku Goshinki destroys it with its teeth and Toto-sai has to fix it with one of Inuyasha's fangs.
I think that it's episode 157: Destroy Naraku With the Adamant Barrage! I like this episode too.
First "Inuyasha" slashes her arm, but "Inuyasha" was really Naraku. So that's why she pinned him to a tree. Then she dies. Then Naraku pushes her off a cliff.
Technically, kikyo doesn't help Naraku kill Inuyasha because naraku never really kills Inuyasha. But, in one of the episodes in 2nd series, Kikyo steals Kagome's jewel shards and gives them to Naraku making him stronger.
Tsubaki absorbs the Ogre Demon in episode 64 which gives her a demonic aura and Inuyasha is able to use his Backlash Wave on her. The demons she had absorbed are destroyed and one of Naraku's insects takes the sacred jewel and she dies.
i think kikyo kills naraku go on youtube and type in your question.
he is traped by naraku and inuyasha and kagome save him
