Hanyō no Yashahime

is the anime-only spin-off to InuYasha, and focuses on Sesshōmaru's twin daughters, Towa and Setsuna, as well as Inuyasha's daughter, Moroha.

Rumiko Takahashi designed the main characters, but she is not responsible for the story or writing. It will be aired in October 2020.

Summary
The daughters of Sesshōmaru and Inuyasha set out on a journey transcending time. In Feudal Japan, half-demon twins Towa and Setsuna are separated from each other during a forest fire. While desperately searching for her younger sister, Towa wanders into a mysterious tunnel that sends her into present-day Japan, where she is found and raised by Kagome Higurashi's younger brother, Sōta, and his family.

Ten years later, the tunnel that connects the two eras has reopened, allowing Towa to be reunited with Setsuna, who is now a demon slayer working for Kohaku. But to Towa's shock, Setsuna appears to have lost all memories of her older sister.

Joined by Moroha, the only daughter of Inuyasha and Kagome, the three young women travel between the two eras on an adventure to regain their missing past.
