Onigumo



Onigumo was a thief rescued by the priestess named Kikyo. He was an evil human being who gained his injuries in a fire caused by Rasetsu he betrayed. Kikyo found him and nursed his injuries, and, occasionally, Kikyo's younger sister Kaede took care of him as well, even though she didn't like doing it. Onigumo gave up his body to demons in order to regain his strength, mobility, and power. This created the evil half-demon Naraku who then immediately tricked Inuyasha and Kikyo into becoming enemies so he could have the sacred jewel for even more power than he already had. His deceit led to Kikyo's death and Inuyasha's sealing to the Tree of Ages. When Naraku removed his human heart, he also removed Onigumo's soul in the process, which became Muso. Much later, Muso finally remembers about his past as a bandit and of his time with Kikyo within the cave.

Reuniting with Naraku
Realizing he was not yet ready to part with Onigumo's soul, Naraku confronted Muso and tried to absorb him back into his body. Inuyasha interfered, enabling Muso to run, but he foolishly went back to kill Naraku for revenge. Muso impaled Naraku but Naraku drew him in and absorbed him as he screamed for Kikyo, Kagura looking on as she thought, "If I'm not careful, that will be my ultimate fate..."

Final Death
In one of Naraku's final moments he recalled that Kagome said the the Jewel did not grant his real wish. Naraku recalls that what he really wished for was Kikyo's love, but it seemed that it was not granted to him. Before Kagome's arrow pierced the jewel, Naraku comments that he won't be able to go where Kikyo has gone. It is presumed that Onigumo's emotions have somehow surfaced within Naraku as he recalled his true wish.

Trivia

 * Onigumo had a Spider mark on his back, even before he became Naraku.
