One decade later, the fourteen-year-old twin half-demon daughters of Sesshōmaru and Rin, along with their cousin, the quarter-demon daughter of Inuyasha and Kagome Higurashi, 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.

One decade later, the Sacred Tree of Ages' time-traveling portal that connects the two five-century timelines reopens, allowing Towa to be reunited with Setsuna, who is now a hardhearted warrior and demon slayer working under the adult Kohaku. But to Towa's shock, Setsuna had lost all memories of their strong and close sisterly love and girlhood in the forest.

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

''The destiny inherited from their paternal lineage! The counterattack of the granddaughters who have gotten new powers! The Half-Demon Princesses' ultimate mission is revealed!''
 * -|Season 2=

Towa, elder twin daughter of Sesshōmaru and, who grew up in the modern era since being transported there at age four, finally returned to the feudal era and looked for the Dream Butterfly to restore her twin sister Setsuna's memories and sleep. Zero, elder sister of the sacred Beast King Kirinmaru, who is thought to be linked to the butterfly, sees half demons with hostility due to a prophecy about her brother being defeated by a half demon, and she plans to defeat Towa and the others. Towa and Setsuna have the powerful dog-demon Sesshōmaru as their father and the young adult human Rin as their mother. Their good friend and half-cousin Moroha, is a quarter demon born between a half dog-demon, Inuyasha and a time-traveling upper-level human priestess, Kagome Higurashi.

Right after being born, Zero aims at their lives, however, Towa is sent to the modern era, Setsuna starts living in the half-demon village and Moroha is under the protection of the Wolf Demon Tribe.

Fourteen years ago, Inuyasha and Kagome Higurashi were involved in a battle against the beast king Kirinmaru and were sent to the tomb of the Great Dog-Demon, Sesshōmaru and Inuyasha's father, which was hidden inside the Black Pearl.

Despite being half-demons and a quarter-demon, Towa, Setsuna and Moroha give an excellent performance and Kirinmaru finally gets serious by murdering Setsuna. Sesshōmaru appears in front of Towa, who is deeply lamenting on what happened, offers her the Tenseiga and asks her "Won't you try this, Towa?" However, Tenseiga, which is known as a healing sword that can save a hundred lives in a single stroke, is broken. What will the broken Tenseiga do? Will Setsuna's lost life be called back by it? What will be the answer that Towa finds in the middle of the rain?

While dealing with the afterlife imps, Towa uses every ounce of her demonic energy to return Setsuna to life as she falls unconscious due to being spent by using up all of her powers. Sesshōmaru calls out to his youngest daughter's name as Setsuna wakes up from the dead and uses her upgraded naginata, the Yukari no Tachikiri to easily eradicate countless demons. Moroha is reunited with her revived cousin once more much to her joy and Towa later on as she wakes up to Setsuna.

The Half-Demon Princesses then head on a journey to find a proper demonic weapon for Towa in place the broken replica of the Kikujūmonji sword. Upon reaching Mount Musubi, home of the Dream Butterfly, they encounter Rion, the undead teenage daughter of Kirinmaru, who presents Towa with the legendary demonic sword of the almighty God of the Stars, the Zanseiken! Upon encountering his teenage daughters' and half-niece, Sesshōmaru cuts down the Dream Butterfly that has been stealing Setsuna's sleep and dreams, further endangering Rin's life.

With Riku and a resurrected Rion now their allies, the Half-Demon Princesses set their sights on taking down Zero in order to save Rin from her fatal Silver Scale Curse and follow up on the Sacred Tree of Ages' request on ending Kirinmaru in order to preserve everything that exists from being plunged into the Degenerate Age. They succeed with Kirinmaru willingly dying of his own wish in order to truly be with his beloved daughter and sister, and everyone returns to their daily lives. It is then that the Half-Demon Princesses are given a new journey in the western lands with a fully revived Riku alongside them.

 * The anime uses demons from the manga that were ignored in the making of The Final Act.

 * Towa announces the episode titles, similarly to how Inuyasha did in the original series and The Final Act.

 * Even Rumiko herself never considered Rin and Sesshomaru becoming a couple; having stated he was Rin's guardian.
