Muotoko

was a demon born of the regrets of man.

History
He was hired by Jaken to steal Inuyasha's Tessaiga. He stole various items from Inuyasha's friends while they were blinded by a fog bank. He returned to Jaken with other belongings from Inuyasha's gang, including their shards of the Shikon no Tama, and said that he didn't take the Tessaiga because it was a rusty blade. He lured Inuyasha's group to him with a smoke signal. As he attempted to steal the sword, he was repelled by Tessaiga's barrier. He returned all the things that he stole. Inuyasha's group made him promise not to steal again, or they would be forced to kill him.

Personality
Shippō explained that the combined sadness and bitterness of man's losses during the dangerous times of the Feudal Era gave rise to the Nothing Man's birth.
