Sesshōmaru's mother

Sesshōmaru's mother is an inu daiyōkai who lives in a large mansion in the sky and the first wife of Tōga, who fathered their son. She held the Meidō Stone, which was given to her by Tōga, who instructed that she should use it and not feel fear nor sadness should Sesshōmaru ever approach her seeking information about the Tenseiga, even if testing their son's abilities meant putting his life in danger.
