Mu-on'na

The Unmother is a yokai that is born through the grief of mother's suffering the loss of children to famine and war. The unmother seeks to fill the void within herself by taking the souls of others. The Unmother is a master of illusions so long as their is water for her spell to work. The Unmother absorbs a person's soul by absorbing their body into herself via the chest and appears to have skin like putty when Jakken smashed his staff into her face, and all it did was mishape it. The Unmother can also look into people's souls but generally doesnt since it's primary concern is absorbing her victim into herself.

The Unmother wore a pink robe with blue lining and is faceless except when using her spells to take on the form of a person's mother.

The yokai that tried to absorb Inuyasha into her body but was first prevented by Jakken until the location of Inuyasha's Father's tomb could be found. When Jakken was knocked aside by Kagome the Unmother fled across the marsh in the hopes of absorbing Inuyasha despite Kagome's efforts but was unsuccessful in fully doing so. When Kagome realized the reflection in the water was the Unmother's spell, she splashed the water where the reflection of her and Inuyasha was. Thus releashing Inuyasha in a cry of pain and anguish. Seshomaru used her to obtain the location of his father's grave but killed her after she protected Inuyasha from his attack. Also known as "muuonna" or "nothing woman".
