Izayoi

Izayoi was a beautiful woman of pale skin, bright brown eyes, and waist-length black hair with bangs hanging on either side. She also wore makeup. She was so beautiful and glamorous that her beauty and attractiveness were considered without any equals.

Izayoi typically wore a jūnihitoe, traditional hime cut of noble ladies. She wore a simple kimono when giving birth (probably what she wore towards the end of her pregnancy) and the Robe of the Fire-Rat that her husband gave before his death.

A princess and the human mother of Inuyasha, whom the dog daiyōkai Tōga fell in love with, angering Takemaru, who was also in love with Izayoi.

Little was known about her life, including how Izayoi met Tōga, although it appeared that the two shared a close bond - the sword Tessaiga, formed from Tōga's fang, was created to protect her, as was the Robe of the Fire-Rat. In a rather unexpected turn of events, Tōga's demon mate made an appearance late in the series and brought about even more unanswered questions, though she remarked how her son Sesshōmaru was similar to his father in regard to his care of Rin.

​​​​Izayoi was stated to be married to Tōga and eventually got pregnant with his child, a hanyō. It is stated that Inuyasha was born in an isolated location and into poverty. The character of Inuyasha's mother only appeared once as herself in the series and had no lines. The character was introduced by Sesshōmaru, who used a yōkai to make a perfect duplicate of Izayoi in order to trick Inuyasha into revealing the whereabouts of their father's demon sword, the Tessaiga. He blamed Izayoi for his father's death and claimed that she had made Tōga weak, which led to his death. The ruse was eventually discovered, however, although not before the location of the sword was found. Due to a random event, she was brought back to life and now lives alone, hoping one day she can see her son Inuyasha or have a love life again.

zayoi was shown to be a kind-hearted, gentle, and soft-spoken woman who cared much for her family. She was always portrayed with a solemn, yet graceful appearance. Although little was shown about her both in the anime and manga, the third InuYasha Movie showed how deep the love between her and her husband was, mentioned several times by friends and foes of Tōga.

Izayoi was warm and empathetic, being the only person who comforted Inuyasha during his childhood when people called him a "half-breed" and was saddened for she could only imagine what life could be like for her son: not fitting into either the human or the demon world. She also was kind with Takemaru, the man who admitted that he loved her, wanting to save him from Tōga's wrath despite what the former did to her, but the two men died in the fire at the end.
