In English, it is translated as Yashahime: Princess Half-Demon or simply Princess Half-Demon.

A second season, titled "The Second Act", was confirmed on the nineteenth of March. It may air in October 2021.

Summary
A flashback narrative six months after the events of The Final Act finale. InuYasha and Kagome fight Ne no Kubi that Kikyō sealed away right before meeting InuYasha, over half a century ago.

Over a decade later, the fourteen-year-old daughters of Sesshōmaru and Inuyasha set out on a journey transcending time itself. In Feudal Japan, fraternal half-demon twins Towa and Setsuna are separated from each other during a forest fire at the age of four. While desperately searching for her twin, Towa is sucked into a mysterious tunnel that sends her into the Modern era, 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 hardhearted warrior and demon slayer working for Kohaku. But to Towa's shock, Setsuna appears to have lost all memories of her and her childhood.

Joined by Moroha, the only child of Inuyasha and Kagome Higurashi, the three travel between the two eras on an adventure to regain their missing past and resolve the apocalyptic crisis that is far more dangerous than Naraku and the Shikon Jewel ever were.

Season Two: The Second Act
It will focus on Towa finally starting to further develop and harness her true demonic powers into the broken Tenseiga that was just bequeathed to her by her father Sesshōmaru into calling forth another equally powerful heavenly sword known as the Yukari no Tachikiri. Setsuna is returned to life, probably by Towa's newfound demon sword or her combining her own demonic energy with that of Tensaiga's healing ability, and begins manifesting her very own demon sword from her left arm- the Blood Blade. The Half-Demon Princesses then continue their journey to find answers about themselves and Kirinmaru, all while encountering Riku and Zero and other new adversaries along the way as they try again to recover the Rainbow Pearls.

More light will be shed on the mysterious new Windmill of Time and its true function, as with the Pinwheel of the tiny demon Akuru. Moroha will also learn about what befell her parents when she was born; several more emergence of the essence of the Sacred Tree of Ages itself and the mysterious connection Rin has with Lady Zero.
