Yashahime: Princess Half-Demon (Japanese: 半妖の夜叉姫, Hepburn: Han'yō no Yashahime) is a Japanese anime television series produced and animated by Sunrise. It is a sequel spin-off to the Inuyasha anime television series, which itself is based on Rumiko Takahashi's manga series of the same title. The series follows the adventures of Towa Higurashi and Setsuna, Sesshomaru and Rin's fraternal twin daughters, and Moroha, Inuyasha and Kagome Higurashi's daughter.

The series' first season aired from October 2020 to March 2021; the second one aired from October 2021 to March 2022. Viz Media has licensed the series in North America, while Medialink has licensed it for Southeast Asian and South Asian territories.

A manga adaptation, illustrated by Takashi Shiina, started in Shogakukan's shōnen manga magazine Shōnen Sunday S in September 2021.

Ten years after the events of Inuyasha, Sesshomaru and Rin's daughter Towa is separated from her twin sister Setsuna, and gets stranded in the modern era, where she is adopted into the family of her father's sister-in-law, Kagome Higurashi, raised by Kagome's younger brother Sōta and his warmhearted wife Moe. Towa becomes close to her younger adopted sister, six-year-old Mei, who is Towa's “substitute” for Setsuna.

One decade later, Towa is reunited with Setsuna, when she leaves the modern era through the vast time-traveling power of the spiritual Sacred Tree of Ages. During their separation, Setsuna became one of the demon-slayers working with Kohaku and did not remember her past, as the mythical Dream Butterfly stole her dreams and memories. To restore them, the half-demon twins embark on an adventure, alongside their half-demon bounty hunter cousin Moroha, the fourteen-year-old daughter of Kagome and Inuyasha, who lacks full knowledge of her parents' fate; except that her human mother is an uppermost-level priestess and that her equally impulsive and overconfident father is half dog-demon and half-human, just like her half-first twin cousins.

At times, the vital essence of the Sacred Tree of Ages awakens from centuries of dormancy to warn them that a long-standing rival of their paternal dog-demon grandfather is plotting to warp time itself since Sesshomaru refuses to fight him directly in place of his late father. At the same time, the unparalleled time-based unsurpassable entity is harboring adult Rin in suspended animation for her husband Sesshomaru due to her fatal connection to Zero, the elder sister of Kirinmaru and creator of the seven mystical Rainbow Pearls, whose respective mighty demonic abilities rival those of the Sacred Jewel of Four Souls itself. During a battle with Kirinmaru at the ruins of Izayoi's mansion, Setsuna is seemingly killed by Kirinmaru. Still, Towa uses the broken Tenseiga to revive Setsuna.

Setsuna has her Kanemitsu no Tomoe upgraded by Tōtōsai into the mighty Yukari no Tachikiri, which can cut the invisible red threads of fate. Towa receives the legendary cosmic sword Zanseiken from Kirinmaru's late daughter Rion, whose soul is contained within an artificial body created by her father. The Half-Demon Princesses must become strong enough to save Rin before she perishes from the fatal curse placed on her by the deeply bitter Zero. Ultimately, Zero lifts the curse herself and passes it on to the afterlife. As Towa and Setsuna are ready to reunite with Rin, Kirinmaru requests Moroha to save her parents or steal Akuru's pinwheel.

Sesshomaru and Kirinmaru's duel recommences, with the former taking the hit for his twin daughters and half-niece, which fatally wounds and weakens him. He manages to use his remaining strength to send them into the Black Pearl, where the girls meet Inuyasha and Kagome Higurashi. After escaping from the Black Pearl using the combined powers of both Tessaiga and Tenseiga, the group discovers that Kirinmaru's true objective is to travel to the Reiwa Era to destroy the Grim Comet that threatens to destroy human civilization, and become a supreme ruler over all humans and demons alike. After saving Sesshomaru, Towa discovers that Kirinmaru allowed her to keep Zanseiken so that her soul is eventually extinguished by using its power so that he can use her body as a living vessel for Rion against the wishes of his undead daughter while Moroha is given a spiritually-empowered longbow made by Inuyasha and Kagome, which greatly boosts the effectiveness and spiritual energies of her sacred arrows.

Using Akuru's time-based pinwheel, the Half-Demon Princesses travel back to the modern era to destroy the comet themselves, with Kirinmaru chasing after them. They encounter Osamu Kirin, formerly Kirinmaru's right arm, and Towa's homeroom teacher, who informs them about his desire to save humanity. However, he double-crosses the girls and brings the Grim Comet to the feudal era to grant Kirinmaru's wish in obliterating it from the plane of existence and show Rion various countries and states from around the modern world. With the last of his strength, Akuru opens the gateway to the ancient past on the Sacred Tree of Ages, so the Princesses can return to help their parents' and their closest friends in preventing the Degenerate Age from progressing further.
