Sesshōmaru's mother

is an inu daiyōkai who lives in a large castle 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 not sadness should Sesshōmaru ever approach her seeking information about the Tenseiga, even if testing their son's abilities meant putting his life in danger.

Personality
In demeanor, she appears to be a slightly haughty woman with a certain playfulness, as she does not recall other individuals' names and states that her son didn't inherit his father's charm. She is open about her opinions and feelings, calmly revealing her thoughts about her family to Jaken, something Sesshōmaru would have never allowed himself to do.

Similar to Sesshōmaru, his mother is a rather graceful individual that acts with apparent indifference, only casually concerned about the possibility of her son's death while observing his trial, and being mildly offended after he refuses the escape route she provides for him. She may have had an influence on Sesshōmaru's initial attitude toward humans, inquiring if he was planning to eat ​​​​​​Rin and Kohaku after observing they followed him.

Despite these qualities, she is shown to have a good heart, applauding her son for seeking to perfect the Tenseiga as an instrument of healing, rather than a weapon for destruction. She lectures him about the qualities of the wielder of the Tenseiga, emphasizing the need for compassion, love, and a pure heart.

She also cares about Sesshōmaru and protects him in subtle ways; when Kirinmaru told her he suspects Sesshōmaru's true goal is protecting his daughters, Sesshōmaru's mother told Kirinmaru doing so goes against his nature, even though she played a key role in teaching Sesshōmaru compassion years earlier.

Physical Description
She appears as a beautiful, slender woman of pale skin. She has pointed ears, slanted golden eyes with slit pupils, and long silver hair with short bangs. She has a violet crescent moon on her forehead, a small magenta lightning-like stripe on each cheek, and a matching stripe on each eyelid. Able to transform into a massive dog, she spent most of her time in humanoid form, similar to her son's.

Outfit
She wears a white and violet kimono with green and yellow butterfly designs on it, and a navy outer wrap that had a fur pelt, which wrapped around her chest. At the end of her outer wrap, there is also another fur pelt. In addition, she has a bright sky blue necklace with an amulet of the Meidō Stone.

Powers & Abilities

 * Longevity: As a daiyōkai, she has supernatural longevity. She appears to be physically a young grown woman despite being older than her centuries old son.
 * Dog Form: Like Sesshōmaru and Tōga, she was able to transform into a giant dog. This gave her an incredible increase in strength, among other abilities.
 * Flight: She is capable of independent flight in her giant dog demon form, even in extreme heights.

Weapons

 * Meidō Stone: With the stone, she was able to open and close portals to Hell itself. She was also able to summon hellish creatures to do her bidding and snatch souls to revive someone, as seen when she revived Rin.

Family
She was the first wife of the Great Dog Demon. Not much was known about their relationship beyond the fact that they had Sesshōmaru together before he met Izayoi. It could be indicated that she still did love her estranged husband deeply and still thought highly of him, mentioning him quite a few times when Sesshōmaru's group met her, apparently being fond of his "charm," and seemed to value the life lessons that he had left her to teach to their son. She pointed out his odd fascination with humans, but respected it nonetheless. Zero also indicated that his death had affected her more than she showed and that she not only felt grief but also hatred at Izayoi for leading him to his death and though she remained dismissive over Izayoi's humanity, she never denied Zero's accusations of her feelings over her estranged husband's death, suggesting there is some truth to it.
 * Tōga

She was a powerful demon who gave birth to Sesshōmaru, though she sometimes seemed unconcerned for his actions. Actually, she was shown to be quite the authority figure who wasn't afraid to scold him if she felt that he acted childish and too full of pride, eventually taught him about the value of life. Despite her harsh nature toward him, she truly did love her son and wanted what was best for him, resurrecting Rin a second time to make Sesshōmaru happy. She later on showed her concern for her son's happiness by being clearly displeased when Zero revealed he was likely miserable as her death meant Rin would die as well.
 * Sesshōmaru

Since Rin was a little girl and a human, Sesshōmaru's mother didn't really like her as a person, but she was curious about why Sesshōmaru allowed this girl to travel with him. She only resurrected Rin in order to make her son happy, informing the young human that she should take care of her life from now on and not die again. She also knew that she and Sesshōmaru got married, just like his father: Although she didn't seem to care much for their children's lives, she was clearly displeased when Zero revealed she had bound her life to Rin's so when she dies Rin would die too (which means she has been casted a spell by Zero and sealed her inside the Sacred Tree of Ages and lay into a deep sleep), showing she does care for her, if only for the humanity and happiness she brought her son, and out of guilt for resenting Izayoi. She also did nothing to Rin when Zero was saved by Sesshōmaru with the Tensaiga despite stating that she wouldn't allow another resurrection to occur for her.
 * Rin

While around Kirinmaru at least, she puts up a facade of thinking quite lowly about her granddaughters and step-granddaughter, stating she doesn't care about their lives and deaths, though at the same time she shows disapproval of Zero's fanatical desire to kill them just like Kirinmaru. However, when in private, it was shown that she at least didn't wish for their deaths and actually does seem to care for them, as she was visibly pleased when she learnt they had won against Zero and briefly killed her, even expressing some pride over their ability to kill the woman who she had long since disdained.
 * Towa, Setsuna, and Moroha

Others
Though Jaken introduced himself towards her by name, she only referred to Jaken as little demon much to his disgrace, though he always kept telling her what his name was, but she never reacted to his attempts to become more familiar. Despite her haughty attitude about not using his name, she did talk in a calm, polite manner towards Jaken and didn't seem to look down on him since he was a normal or low class yōkai as an imp while she was a daiyōkai. While Sesshōmaru was inside the Meidō to rescue Rin's life, Jaken stayed with his master's mother and started to converse with her, as she asked him about Sesshōmaru's relationship with Rin and what she means to him. She seemed to trust Jaken, mentioning her honest thoughts about Sesshōmaru, his father, and her opinions on humans, having no trouble to speak such private thoughts freely to him as they were discussing the matter of Sesshōmaru's return and Rin's life.
 * Jaken

Since Kohaku was a human demon slayer, Sesshōmaru's mother didn't really like him as a person, but she was curious about why Sesshōmaru allowed this boy to travel with him. Kohaku survived in the path to the Underworld because of the Shikon Jewel shard, it surprised her to say the least.
 * Kohaku

During her conversation with Zero, Zero pondered if she was angry and bitter at Izayoi for taking Tōga away from he. Zero speculated that she had took her time to meet Izayoi before she passed through the Underworld. She was dismissive, stating she didn't care for humans, but from how she showed a colder demeanor and how Zero stated she saw through it, indicates she did have some resentment towards Izayoi and may have in fact had a negative encounter with her before she passed on, but she grew ashamed of what she did to Izayoi.
 * Izayoi

She was the first mate of Tōga, who had a second son (from another wife) - Inuyasha - with the human princess. However, it was left unmentioned if she knew any further information about Inuyasha and the two never seemed to meet, since Inuyasha couldn't identify her scent as Sesshōmaru and his mother crossed the skies above where Inuyasha's group was walking. He only stated that the scent of Sesshōmaru and another yōkai was in the air, that it came from the cloud that had been shaped like a dog demon, implying that he had no idea about who Sesshōmaru's mother was, and thus never met her. Since she left her palace and even Jaken did give Kagome the location and when in order to destroy the Grim Comet on the 500th year in the Feudal Era in the evening, Inuyasha felt surprised where Sesshōmaru's mother lived and when he and Kagome arrived to meet his brother and Jaken, but she's not here because she left for her errands.
 * Inuyasha

A fellow Great Demon, they were seen together when Tōga and Kirinmaru confronted the Grim Comet 500 years in the past from the. However, as Zero was in love with the Great Dog Demon, it was natural that she was jealous of her for having his affections once and the dislike between them was clearly mutual. Both of them seem to be aware of the other's feelings over Tōga's death, Zero noting she could tell Sesshōmaru's mother despite her haughty demeanor did feel some sadness and grief over it and felt bitterness towards Izayoi for both taking his heart and causing his death, which she didn't outright deny, and coldly stated she had no regard for humans for the latter's regard, while Sesshōmaru's mother was also aware that Zero hunted down her granddaughters and sought to cause her son pain by linking her life to Rin so when she dies, so does her daughter-in-law, out of irrational jealousy. Clearly displeased with Zero when she revealed her sadistic glee at the idea of her son's suffering and having previously shown disapproval of Zero's relentless desire to kill her granddaughters, she proved to be able to affect Zero more than she affected her, sarcastically stating Zero was almost human-like for her jealousy and making her angry. At the same time, she seemed to have some pity towards Zero, calling her pitiful for being a "women who burns from love".
 * Zero

Kirinmaru treated her with the formal title of your ladyship even when she no longer ruled the Western Land. She seems to be on peaceful terms with him as she seems aware of his intentions with the Windmill of Time.

Trivia

 * Although Rumiko Takahashi never officially gave Sesshōmaru's mother a name (Jaken referred to her respectfully as "Gobodō-sama" (御母堂様), translated as "Lady Mother" in the English dub), some English-speaking fans had nicknamed her "Inukimi," which, if represented by the characters "犬" & "君," means "Dog Ruler" or "Dog Monarch." Some Spanish-speaking fans have also given her the nickname of "Irasue," which may be a mispelling of "Urasue." Not to be confused with Urasue, the evil sorceress who resurrected Kikyō.
 * Her seiyū, Yoshiko Sakakibara, also voiced several characters from Takahashi's previous series. They include Otama, Ogin, and Elle de Rosenbach from Urusei Yatsura, and Ayako from .
 * She may take inspiration from the  in.
