My soul is rancid to the core, yet it still holds value. Feast on my flesh; I must possess my former mobility, then the jewel will be mine, not to the mention the lovely maiden Kikyō. Feast on me, demons. Devour me! And in exchange, bestow me with your mobility and strength!


Onigumo (鬼蜘蛛おにぐも, "Demon Spider") was a murderous bandit who was rescued by the priestess named Kikyō. He fed his body to yōkai and ultimately became Naraku.



Naraku birth

Naraku's birth from Onigumo.

Onigumo was an evil bandit who met and betrayed Rasetsu by telling him to go after Kikyō who he didn't reveal was being protected by Inuyasha. Thinking the half-demon killed Rasetsu, he made off with the bandit army who accepted him as their new leader. However, Rasetsu survived but lost his eye and tracked down the bandits to an inn. Rasetsu confronted the surprised Onigumo and set the building that he was in ablaze. Rasetsu found that Onigumo had barely survived but gained severe injuries in the fire. To complete his revenge, Rasetsu then had his men throw Onigumo off a cliff to finish him while mockingly telling him to find the shard and greet Kikyō. However, Onigumo managed to survive but was crippled by the fall.

This set the events of the series in motion, as Kikyō later found him, nursed his injuries in a cave, and occasionally, Kikyō's younger sister, Kaede took care of him as well, even though she didn't like doing it. Onigumo originally had difficulties accepting Kikyō's kindness, and told her to forget about the bandit when she visited him, but Kikyō's kindness had also made Onigumo fall for her. As a Kodoku spell, Onigumo gave up his body to demons in order to regain his strength, mobility, and power.

Onigumo did that because he desired Kikyō and the Sacred Jewel for himself, then kill Inuyasha and capture Kikyō until she agreed to return his love as his wife, while the demons did it because they wished to get rid of Kikyō and obtain the Sacred Jewel. That created the evil half-demon, Naraku who then immediately tricked Inuyasha and Kikyō into becoming enemies so he could have the sacred jewel for even more power than he already had. His deceit led to Kikyō's death and Inuyasha's sealing to the Tree of Ages.


Onigumo true face

Onigumo's true face.

When Naraku removed his human heart, he also removed Onigumo's soul in the process, which became Musō. Much later, Musō finally remembered about his past as a bandit and of his time with Kikyō within the cave. Musō was eventually absorbed by Naraku and became part of him again. When Naraku returned to the caverns beneath the collapsed Mount Hakurei where Onigumo's voice of his heart is, in which that he thinks that Onigumo was right before from fifty years ago.[1]

Physical description[]

Onigumo's most notable feature was a spider mark on his back, even before he became Naraku. The origin of this strange mark is never revealed.

When Onigumo first appears in Kaede's memories, he appears as a pitiful figure: a crippled man covered in disfiguring burn scars and wrapped head to toe in bloody bandages. His nose was burnt off, as well as his lip in the manga. Onigumo's face was masked in wrappings with the only openings being for his mouth and one remaining eye which was bloodshot from his failing health; the veins around Onigumo's green iris almost resembling a dark spider web.

Before his burns, Onigumo was a young man, presumably somewhere from 17 to 20s, with a toned body and long dark black hair. His face is always out of view in the series and his Musō incarnation had no face, due to him forgetting his face and identity. The manifestation of Onigumo's soul appears in chapter 452 wearing the same face as Naraku, so this is his true face. It turned out into a small spider and entered into Naraku's right hand.


During his life, Onigumo was a bitter and misanthropic individual, being both nihilistic and hedonistic. Onigumo committed many terrible crimes throughout the land and betrayed his comrades without remorse. Onigumo freely defined himself as a wretched villain with a dark heart.

Onigumo's incarnation as Musō stated the only thing that mattered in life were wealth, alcohol and sex. Musō said he enjoyed massacring villagers and that he'll kill anyone he feels like.

After becoming crippled and burned, Onigumo became depressed, he was hostile to Kikyō and tried to dissuade her from keeping him alive. However he came to be obsessed with her and desired her affection above all else, so much that he eagerly sold his soul to yōkai for a chance to get her.



Onigumo knew Inuyasha was protective of Kikyō. He originally wanted the dog hanyō to kill his former bandit leader Rasetsu but this failed. After being crippled, he became madly jealous of Inuyasha's relationship with Kikyō, as he wanted the Miko's attention for himself. When Musō, the memory deprived incarnation of Onigumo, met Inuyasha, he instantly felt a great hatred within him after looking at the face of the dog hanyō and tried to kill him.

After regaining his memories, Musō stated Inuyasha should've died instead of Kikyō and he aims to rectify that mistake right now.


At first, Onigumo was openly hostile to Kikyō and frequently told her to stop taking care of him, however gradually Onigumo's feelings became more complex and he secretly came to look forward to her visits, however he was also bitter that she would never return his feelings. This anger increased when Onigumo found out that Kikyō loved Inuyasha learned by the Three-Eyed Spider.

During a conversation with Kaede, Onigumo claimed Kikyō was too pure and proud, stating he wanted to see Kikyō corrupted with evil just like the Shikon Jewel. When Musō regained his memories, he said Kikyō was arrogant and self righteous, then followed by how he wanted her.

Musō was despondent that Kikyō had been killed by the yōkai in Naraku, stating that Kikyō alone gave meaning to his life and that there were no reason for living if she was gone. When he found out from Naraku that Kikyō was alive, he was overjoyed and attempted to seek her out, yelling Kikyō's name until he was fully absorbed by Naraku.

At Naraku's death, it is revealed Onigumo's heart wished for Kikyō's love on the Shikon Jewel. Both sides want to kill Inuyasha.


Onigumo had a consistently hostile relationship with Kaede; never calling her by name and threatening to corrupt the Jewel and her sister Kikyō. When he met her fifty years later as Musō, Onigumo didn't recognize her and tried to steal her life, saying he had no interest in old women.


At some point, Onigumo met Rasetsu, a bandit leader and told him about the jewel. However this was a set up as Onigumo told him to go alone, planning for Inuyasha to kill Rasetsu allowing Onigumo to take Rasetsu's gang for his own. After Rasetsu's presumed death, with no remorse, Onigumo celebrated his leadership position by partying at an inn.

The surviving Rasetsu took back his men, burnt Onigumo alive with the inn and, when finding out the traitor was still alive, tied him up and tossed Onigumo off a cliff by Kikyō's shrine while telling Onigumo to get the jewel himself.

As an elderly man, Rasetsu, now going by the name of Kansuke, said even his younger self couldn't compare to Onigumo when it came to evil. He believed the jewel shard bringing Naraku's demons after him was Onigumo, somehow haunting him even after his supposed death.


Onigumo: "You, young lass.."
Kaede: "It's Kaede."
Onigumo: "Yes... Your sister possesses what is known as the Shikon Jewel, does she not?"
Kaede: "What would ye know about the jewel?"
Onigumo: "All who are wicked know of it, and pursue it."
Kaede: "Ye included?"
Onigumo: "I understand that the more evil the jewel absorbs, the more evil it becomes; outstanding."
Kaede: "My sister has it under her control, it won't be corrupted."
Onigumo: "Kikyō's manner is self righteous; for once I should like to see her apprehensive and frightened, that would bring me true pleasure."
―Kaede and Onigumo's chilling exchange[src]


  • Onigumo (鬼蜘蛛) can also be translated as the Araneus ventricosus, a particular species of orb-weaving spider.
  • It was Naraku's actions that brought some sense of irony with Onigumo's words of how he would have liked to see Kikyō "apprehensive and frightened", a facial expression that was made as Naraku struck down Kikyō, as he was disguised as Inuyasha, though Musō, Onigumo's later reincarnated form, expressed a large amount of anger and regret as he recalled that bitter memory as Kikyō had died from such a mortal wound due to Naraku's miscalculation.
  • As Musō, while Onigumo did remember about the Shikon Jewel, he apparently did not seem to desire the jewel as much as he did with Kikyō, which implied that Onigumo saw the Shikon Jewel as merely a bonus and his main objective was Kikyō.
