Viz Media has formally announced the forthcoming release of a new spin-off anime series from InuYasha creator Rumiko Takahashi, who also returns as character designer along with production studio Sunrise to create Yashahime: Princess Half-Demon.

Viz Media describes the series:

In Yashahime: Princess Half-Demon, the daughters of Sesshomaru and Inuyasha set out on a journey transcending time. Set 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 brother, Sota, 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 daughter of Inuyasha and Kagome, the three young women travel between the two eras on an adventure to regain their missing past.

Rumiko Takahashi's comments follow below:

“The three heroines are beautifully designed. I am looking forward to their adventures.”

The series will be handled by Teruo Sato, who will direct Yashahime: Princess Half-Demon, along with Katsuyuki Sumisawa on screenplay, while Yoshihito Hishinuma is responsible for animation character design, with music composition from Kaoru Wada. The animation production is by SUNRISE.
