Musō (monk)

Muso(無双, Musō) is separated from Naraku in an attempt to remove his human core, Onigumo, and thus also Onigumo's love for Kikyo. He is the sixth detachment of Naraku. Naraku cares so little for this incarnation that he gives it no name or face; Muso takes both of those for himself from a wandering monk that he kills. Muso ventures to Kikyo's former village, where he runs into InuYasha's group and battles them quickly after their encounter. Soon Naraku quickly realizes, however, that he cannot abandon Onigumo when demons try to gain their freedom from his body, and Muso is absorbed back into Naraku.

Muso had the form of a faceless man with a spider scar on his back. He is faceless because Onigumo was badly burnt before becoming Naraku, even he's face was burnt off. Therefore Muso recieves the same outcome. He goes around killing many people to take their face, eventually ending up with the face of the monk Muso (which is where his name came from). When he comes across InuYasha and the gang, he seems to be immune to their attacks and is even able to regenerate himself after being torn to pieces by the Tessaiga.

Soon after, Naraku re-absorbs Muso since he feels that he has not gotten completely rid of Onigumo and possibly the threat of his death. He decides to try again later when he is stronger.

Meeting Naraku
The poisonous insects take Muso to nearby forest where Naraku is waiting. For the first time ever Naraku and Onigumo come face to face with each other. In the manga Muso instantly attacks Naraku and is absorbed almost immediately. The anime goes into further detail with the encounter. Naraku tells Muso that Kikyo is alive again and she is as he remembers her. Before he can question Naraku about Kikyo InuYasha and Miroku appear. As InuYasha starts a fight with Naraku, Muso runs away. Still angry at Naraku for his imprisonment he decides to go back to kill Naraku. He stabs Naraku in chest however doing this allows Naraku to reabsorb him. Naraku reveals that he still needed Onigumo's heart as a connector for his body, which why he needed to reabsorb him.

Abilities

 * Facial theft - Having been created without a face, Muso can take on facial identities of others by apply faces to his head after ripping them off.


 * Regeneration - Muso demonstrated infuriatingly powerful regenerative abilities, able to piece himself back together even after taking the Wind Scar from Inuyasha. However, had his heart been destroyed, not only his but Naraku's downfalls would have been assured. He also demonstrated the ability to regenerate and shapeshift new limbs, spikes, multiple legs and arms, claws, and a tail.
