Episode 188

Inside Naraku is the 21st episode of InuYasha: The Final Act.

Plot
Naraku recalls his creation after Onigumo offered himself up to demons in order to gain Kikyō and kill Inuyasha. As he remembers his past, he finally absorbs the Shikon Jewel into his body, instantly healing all the damage from his battle with Inuyasha, Sango and Sesshōmaru. In the present, Kagome learns that she will be graduating and going to high school on a wait list. Everyone is thrilled for her, and she attends her graduation ceremony with Eri, Ayumi, and Yuka. Hōjō tries to give Kagome a button from his school uniform as a goodbye present, but she runs off before he can. Heading home to travel back to the past, Grandpa gives her some presents for graduating and her Mother hugs her goodbye, telling her to be careful. In the Feudal Era everyone sees a dark cloud forming on the horizon from Kaede's village and set off for the final battle with Naraku. Inuyasha tells Shippō that he cannot go, and that if they die in battle, he will have to be the one to avenge them. Shippō is about to protest when Inuyasha knocks him unconscious and leaves. Flying through the cloud they see that Naraku has transformed once more and now resembles a huge spider. Byakuya is waiting outside and teases the group. Sesshōmaru rushes past and heads inside Naraku to save Rin. The rest quickly follow. Inside, Naraku taunts them by emerging from the walls, informing them that everything surrounding them is a part of him. He sends armored versions of himself to fight Inuyasha, who's Tessaiga seems useless against them. Sango manages to decapitate one, but it quickly regrows a head and the head grows its own body. Soon the group is separated, with Sango, Kirara and Miroku together and Inuyasha and Kagome on their own. Kagome uses what's left of her limited spiritual abilities to sense out the completed Jewel so that they can get it back from within Naraku, but as they move toward it, Inuyasha transforms into his fully demonic state and begins to attack Kagome, finally knocking her away into a dark chasm.
