Sesshōmaru's mother

Sesshomaru's mother is also an inuyōkai like her deceased mate the Inu no Taishou and as such can transform into a giant dog demon as well as a more human appearance. Although Great Dog Demon sired a child with his human lover Izayoi, it remains uncertain as to whether or not the relationship with Sesshomaru's mother had ended.

Sesshomaru's mother holds the Meidō-Seki, which was given to her by the Inu no Taishou. He told her that if Sesshomaru were to come by to use it and "If you use Meidō-Seki Sesshomaru will be faced with great danger... However, you must not feel fear or sadness." This apparently is another of Great Dog Demon's tests for his son's.

Although her initial appearance towards Sesshomaru are that of an uncaring neutrality, her true emotions towards her son's feelings and well-being should not be questioned. It is only after questioning Sesshomaru in whether or not he was saddened over the death of Rin that she was willing to bring Rin back, later questioning Jaken in whether or not Sesshomaru was happy now that Rin was brought back.

In demeanor she seems similar to Sesshomaru, albeit with a certain playfulness, and probably influenced his initial attitude towards humans; observing Rin and Kohaku following Sesshomaru, she inquires casually if he is planning to eat them. Observing Sesshomaru's trial after activating the Meidō-Seki, she seems at best only casually concerned about the possibility of his death, and after he refuses the escape route she offers, she seems mildly offended, huffing, "Fine. Ignore your mother's kindness," and complaining that, unlike his father, he "completely lacks any charm." However, she does seem to feel concern for her son's well-being, as seen when she brings Rin back to life using the Meidō-Seki after witnessing his reaction to her death.

She appears in episode nine "Sesshomaru in the Underworld" of the second anime series "Inuyasha: The Final Act."
