The Fandom Post is reporting that FUNimation Entertainment has announced that it will be simulcasting the second season of the Yashahime: Princess Half-Demon anime during the Fall 2021 anime season. It was previously reported that the second season of the series is scheduled to premiere in Japan on October 2, 2021.
The story of the series is described as:
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.
