The daughters of Sesshoumaru 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 Higurashi Kagome 's brother, Souta , 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.
