Hanyou no Yashahime: Ni no Shou

Towa uses Tenseiga to defeat imps and save Setsuna, leading to her unconsciousness and the creation of Yukari no Tachikari

Towa exhausts her demonic energy using Tenseiga to defeat afterlife imps and rescue Setsuna, resulting in her fainting. Toutousai arrives, reforges the naginata into a new blade named Yukari no Tachikiri, and warns Setsuna not to die again. Setsuna awakens and utilizes the weapon to eliminate numerous demons. Toutousai temporarily borrows Tenseiga from Sesshoumaru for three days to mend it. Although Towa recovers her powers, Toutousai directs Setsuna to locate a Kyuuyoukon Root from the two-thousand-year-old Magnolia demonic tree Bokusenou. This root is necessary to craft a fully empowered demonic weapon for Towa to replace a sword hilt.

Setsuna confronts a vengeful snake-demon spirit while Towa protects demon-slayers from petrification.

Moroha questions Jyuubei about Bokusenou before joining Setsuna to locate a wise demon. They encounter a snake-demon spirit disguised as a nun, who seeks Setsuna’s waist-length hair to quell her bitterness over losing her true form. Towa arrives wearing mirrored sunglasses to shield demon-slayers from turning into statues. Setsuna then uses the ultimate power of Yukari no Tachikiri to sever both physical and immaterial entities. This act restores the destiny of the snake-demon and her human lover, a fisherman. The spirit finds peace, regains her original form, and returns to the sea. The Half-Demon Princesses depart on Takechiyo while Riku watches from afar, relieved that Towa is safe. He anticipates their next meeting, where Towa will wield a genuine weapon charged with immense demonic energy against the siblings.

The Silver-Scale Curse

Jaken recounts how Lady Zero cursed Rin fourteen years ago, threatening to encase her in silver scales unless Sesshoumaru revealed the location of his newborn twin daughters. To halt the lethal affliction, Jaken placed Rin under the protection of the Sacred Tree of Ages, which kept her in suspended animation while transferring the dreams of four-year-old Setsuna to sustain her life. In the present timeline, the Half-Demon Princesses seek the two-thousand-year-old tree-demon Bokusenou to obtain a Kyuuyoukon Root for Towa’s sword. He directs them to Mount Musubi but omits the powerful demonic energy shield surrounding it. Upon reaching the mountain, the sisters ponder the mysteries ahead, while a transparent red-haired girl sleeps deeply on a glowing scale at the mountain's center.

Moroha breaks through with her sacred arrow into the border between the mortal world and the Afterlife, where she encounters a gigantic skeletal corpse, unaware it is her paternal grandfather. Meanwhile, Inuyasha and Kagome Higurashi reconcile after fourteen years of imprisonment in the demon graveyard. Inuyasha notes the Tessaiga fang is stirring, while Moroha’s arrows react emotionally upon seeing her parents, whom she recognizes from a photo shown by Uncle Sōta.

Elsewhere, Towa is tested by teacher Osamu Kirin, while Setsuna meets the sleeping eighteen-year-old Rin at the Sacred Tree of Ages.

His obsessive paternal love binds her spirit to the earthly plane, prompting her to inhabit an artificial body to halt his ambitions and usher in the Degenerate Age foretold by the Sacred Tree of Ages. Towa acquires the ancient Star-Slicer Flute, which transforms into the immensely powerful star sword Zanseiken. This stellar demonic-empowered blade matches the strength of the Bakuseiken wielded by Kirinmaru. Empowered by this weapon, the Half-Demon Princesses prepare to face any threat sent by Kirinmaru or his elder sister Zero, ensuring they are ready for any challenge.

Outside the castle, Aiya is attacked by an octopus demon but is saved by Hisui, aided by Kin'u's sutras and Gyokotuo's scent-beads. The Lord discovers Aiya's deception and reprimands her severely. Setsuna returns to Kaede's village, where Towa hugs her relieved. Setsuna hides her ordeal from her twin and departs to train Yukari no Tachikiri's divine abilities.

Setsuna suggests Towa return to the modern era, believing she can save Rin and defeat Lord Kirinmaru alone. Meanwhile, Moroha encounters four porcelain mask demons who mock her quarter-demon status. They reveal her parents' legendary feats: Inuyasha defeating Naraku and Kagome imprisoning a powerful daiyōkai within seven months.

Meanwhile, Takechiyo and Hachi hide in a cave while Moroha sleeps after using her late grandmother's shell rouge. In Gokoku Village, the Demon-Slayers seek to calm the Flame Bulls and appease Mayonaka. Setsuna discovers Mayonaka was deceived by villagers and Oharu, the headman's daughter whom he loved. To help him move on, she uses Yukari no Tachikiri to sever his golden fate thread from the Blessing of the Five Grains. The thread reveals Oharu's long-dead body, shocking Mayonaka.

Meanwhile, Setsuna, who remains human, places her trust in Hisui and other demon-slayers to handle the snow demons pursuing her. In a separate storyline, Moroha persists in completing the mission initiated by her parents, aiming to restore Takechiyo to his rightful position within the Raccoon-Dog Clan.
