Plot
Akuru heals Towa with his pinwheel and the Sacred Tree of Ages' essence appears to inform Towa and Setsuna that they and Moroha have been chosen by Akuru to destroy the Grim Comet as well as "the foreign body" in the modern era. Rin then tells her twin daughters that they must do what they were destined to do and return safely, so that they can finally get a big hug from their parents for their heroic deeds. The twins assure their human mother that they will return and leave with Jaken to use the Windmill of Time to go to the modern era with aid from their dog-demon grandmother. Rin then sheds the tears she has been holding back and wonders if letting her daughters' go into such danger was all for the best, to which a still weakened and recovering Sesshōmaru smiles at his wife reassuringly.

At the Bone-Eater's Well, Moroha has been catching up with her long-lost parents who present her with a longbow made from materials from her grandfather's tomb and Inuyasha's silver-white hair. Kagome also tells her daughter that the Bone-Eater's Well is where she came from to the feudal era, that it is a very special place for her and Inuyasha. The family reunion is interrupted by the reappearance of Kirinmaru who demands that Sesshōmaru come out. Inuyasha tells Kagome and Moroha to stand back as he fights the one responsible for their fourteen-year separation. Kagome assures him that she will be fine, and Moroha says that she will never run away from any fight as she has survived this long on her own. Inuyasha unleashes with his Wind Scar and Adamant Barrage attacks, but Kirinmaru is strong enough to withstand them. Kagome and Moroha attack with sacred arrows, but have no more luck than Inuyasha in doing away with the rogue beast king.

Incensed at the constant inference from Tōga's sons, daughter-in-laws, and granddaughters, Kirinmaru is more determined than ever to bring the remaining members of the Dog-Demon clan and all those who follow them to an end. Inuyasha attempts to end him with his own demonic energy-based attack with Backlash Wave, but it, too, is ineffective as Kirinmaru's demonic aura is immensely stronger. He is disturbed at seeing Moroha, who is using her parents' gift to supercharge an arrow with more spiritual power, who fires the enhanced sacred arrow, causing him to dodge it, much to his anger at resorting to such cowardly tactics. Having had more than enough of "further acts of insolence" the beast king retaliates with a strong blast of his purple demonic energy, but the demonic energy shield from Tessaiga's sheath leave parents and daughter unscathed.

Towa and Setsuna arrive and tell Moroha that they must go to the modern era to annihilate the Grim Comet, which shocks and infuriates Kirinmaru as he wants to do just that and be worshiped as a god by humanity. Moroha notices Akuru pulling her as insistence for her to join her twin half-cousins on their journey through time. Inuyasha tells his daughter to go one ahead as it is her destiny to be with her friends. Jaken goes to show the Half-Demon Princesses the way. Kirinmaru is about to be in pursuit but is stopped at sword point by Inuyasha who will never let Kirinmaru lay even one finger on his daughter. Takechiyo offers to take them to the palace of Sesshōmaru's dog-demon mother faster by riding on him as usual.

Trivia

 * Akuru or his pinwheel is shown to have some sort of healing ability as he uses this power to revitalize Towa.
 * Akuru makes direct physical contact with the Half-Demon Princesses for the first time.
 * Inuyasha battles Kirinmaru for the first time alongside his wife and teenage daughter.
 * Moroha gets a new weapon, a longbow made out of Inuyasha's sliver-white hair and materials from her grandfather's grave. It seems to boost her spiritual powers somewhat like Kagome's longbow does for hers.
 * Miroku and Sango retain their old running gag of her slapping him for touching her behind even after all these years. Showing they are more casual about it; since they carry on with the conversation after she strikes him.
 * Rion becoming unable to move without enough haku to sustain her artificial body is reminiscent of Kikyō to when she was deprived of the spirits of the departed without her Soul Collectors nearby.
 * Inuyasha utilizes his Backlash Wave for the first time in the spinoff.
 * Kirinmaru seems to fear Moroha's ever developing and strengthening innate spiritual powers, as he had expressed uncertainty and fright when the quarter-demon was supercharging an arrow with even more spiritual energy, a feat she had never done so beforehand.
 * Miroku's spiritually-infused staff is returned to him by his wife who is wielding her greatly enhanced Black Hiraikotsu.

Error

 * As Kin'u and Gyokuto rides on Hachi, there's missing pinpoints in his eyes.
