Naraku

Naraku is a hanyo (half-demon) created from the heart of Onigumo and the various pieces of other demons. At first, Naraku seems to ask for the assistance of Sesshomaru to kill his (then) rival InuYasha in exchange for an arm that could openly handle the power of the Tessaiga. Ultimately that plan failed, and Sesshomaru sought to kill Naraku at all costs. Naraku hid for a while, and then reappeared at a castle that was being under attack by demons. Sango, as well as the complete demon slayer village was called over to slay the demon, only to be killed by Kohaku, who was being possessed with a spider web by Naraku.

Naraku then formed as the prince of the castle, and used a demon puppet to fake a conversation in order to lure Sango to kill InuYasha. Naraku's plan failed, however due to the proof that Naraku did indeed kill the residents of the Demon Slayer village. Naraku then reappeared with a relatively strong barrier, and with two demon incarnations, Kanna and Kagura. After Inuyasha is defeated by Naraku and his new incarnations he is wounded greatly. While Inuyasha is recovering Naraku sends out his newest incarnation Goshinki. Goshinki is a large purple demon with gleaming red eyes and the ability to read minds. After Inuyasha defeats Goshinki his fangs are used to make Sesshomaru's Tokijin.

Naraku soon makes more incarnations. His 4th incarnation is Juromaru a powerful demon that relies on brute strength. After Koga challenges Naraku he instead must fight Juromaru, Koga flees from battle as he explains to Ginta and Hakaku that he got an erie feeling from Juromaru. Inuyasha soon challenges Juromaru to a battle, but when Naraku releases his shackles he slices his head off. Juromaru releases his elder brother Kageromaru who has been sleeping in his belly. Kageromaru is a demon with long white hair a miniature human head and a grey worm like body with sickle like claws. As the battle progesses Sango and Miroku become injured and Koga saves Kagome from Kageromaru. Inuyasha defeats Kageromaru and Juromaru with his wind Scar (Kaze No Kizu in Japenese) in an effort to save Koga.

Kagura discovers that Koga of the wolf Demon tribe has almost found Naraku's castle and Kagura decides to kill him and take his Shards of the Shikon No Tama. She engages Koga into a battle using her dance of the dead to conjure her zombie warriors to attack Koga. Kagura eventually uses her Dance of the Blades to cut the shikon shards out of Koga's feet. Kagura wanting to be free of Naraku she offers Sesshomaru a chance to kill him and in return he gains Koga's shikon shards. He refuses the offer and angers Kagura greatly. Inuaysha's group finds Koga injured but they can be of little help since it is the night of the full moon Inuyasha reverts back to his human form and loses his Yokai powers. Inuyasha's group catches up to Kagura and Koga challenges here again but is defeated. Inuyasha still in his human form Defends Koga from the final blow and inevitably Kagura gets a glimpse of his human form. He overpowers Kagura and almost killed her if Naraku's demon's had'nt protected her form the wind scar. Naraku learning of Kagura's betrayal calls her back to the castle. Kagura finds a room below the cellar and a tentacle pulls her in. When she gets up she see's a room filled with the Demons that make up Naraku's form. She discovers that Naraku is a half demon just like Inuyasha. She pulled to Naraku's head and warned she will get no second chance.
