A decade after the final battle againstNaraku,Sesshomaru andRin's daughter Towa is separated from her twin sister Setsuna and becomes stranded in themodern era. She is adopted by theHigurashi family, raised bySōta Higurashi, his wifeMoe, and their daughterMei. Years later, Towa reunites with Setsuna after passing through the Sacred Tree of Ages, discovering that her sister has become a demon slayer underKohaku's guidance but has lost her memories due to the influence of the Dream Butterfly. Determined to restore Setsuna's past, the twins embark on a journey alongside their cousin Moroha, the daughter ofKagome andInuyasha, who knows little of her parents beyond their identities as a powerfulpriestess and a half-demon warrior.
The Sacred Tree of Ages occasionally awakens to warn them of a looming threat—an ancient rival of their grandfather, theGreat Dog-Demon, who seeks to manipulate time itself. Sesshomaru, unwilling to confront this enemy directly, remains distant while Rin is kept insuspended animation by a powerful time-manipulating entity. Her life is tied toZero, the elder sister ofKirinmaru and creator of the Rainbow Pearls, whose powers rival the Sacred Jewel of Four Souls.
During a confrontation at the ruins ofIzayoi's mansion, Setsuna is seemingly slain by Kirinmaru, but Towa revives her using the reforged Tenseiga, now named Yukari no Tachikiri, a blade capable of severing thethreads of fate. Towa also inherits the Zanseiken fromRion, Kirinmaru's deceased daughter, whose soul resides within an artificial body. The twins eventually reunite with Rin after Zero lifts her curse, though Zero perishes soon after. Meanwhile, Kirinmaru forces Moroha to choose between rescuing her parents or seizing Akuru'stime-altering pinwheel.
Sesshomaru and Kirinmaru resume their battle, with the former shielding the twins at great personal cost. Weakened, Sesshomaru sends them into the Black Pearl, where they encounter Inuyasha and Kagome. After escaping, they learn Kirinmaru's true goal: to travel to theReiwa era and destroy theGrim Comet, a celestial threat to humanity, intending to rule over both humans anddemons. Towa later realizes Kirinmaru allowed her to wield Zanseiken so he could eventually claim her body as a vessel for Rion, while Moroha receives a spiritually enhanced longbow crafted by her parents.
Using Akuru's pinwheel, the twins return to the modern era to confront the comet, pursued by Kirinmaru. They meetOsamu Kirin, Kirinmaru's former subordinate and Towa's teacher, who initially claims to share their goals but betrays them by transporting the comet to the feudal era. Akuru sacrifices himself to reopen thegateway, allowing the twins to rejoin their family and prevent the coming of the Degenerate Age.
