Episode 15 (Hanyō no Yashahime)

"Farewell Under the Lunar Eclipse" is the fifteenth episode of Hanyo no Yashahime.

Synopsis
What happened to Towa, Setsuna and Moroha's parents, Sesshōmaru and Inuyasha and Kagome... Riku begins to speak. It began 18 years ago, when Hosenki II delivered a new black pearl to Inuyasha. Four years later, Towa and Setsuna were born. However, when Sesshōmaru takes away the twins, he hides them in a barrier, because there is someone who aims for the lives of twins. The name of the person who hates Hanyō is Zero, Kirinmaru's older sister. It was predicted that it would be neither a human being nor a demon who defeats Kirinmaru.

Plot
Riku reveals that 18 years before, he had the Youkai jeweler Housenki II to create the Black Rainbow Pearl using Inuyasha's mother's tincture, which contain her tears of grief for her husband's death, and can create a path to his father's resting place. Housenki then gives the pearl and the tincture to Inuyasha and Kagome respectively, with Inuyasha encrusting the Pearl inside his right eye for safekeeping. A few years later, Rin gives birth to Towa and Setsuna. Riku approaches a pregnant Kagome and warns her about the dangers of the dark comet, which was partially destroyed 500 years ago but a fragment of it is about to fall on Earth and asks for Inuyasha and Sesshōmaru to work together to destroy it, while Zero warns Sesshōmaru that Kirinmaru will surely kill his and Inuyasha's children should he knows about them.

In response, Sesshōmaru takes the newborn Towa and Setsuna with him. Joka attacks him to kill the babies and Sesshomaru cuts her arms away, obtaining the Silver and Gold Rainbow Pearls that he gives to his daughters and Jaken declares that he will take care of them and their mother. He uses his Staff of Two Heads to erect a demon shield around the area.

Meeting with his younger half-brother and Kagome at his mother's palace, Sesshōmaru destroys the dark comet fragment with Inuyasha's help, while Zero awakens Kirinmaru and informs him about Towa, Setsuna and Moroha's existence. Fearing a prophecy left by the Shikon Jewel about Kirinmaru being killed by someone who is both Human and Youkai, Kirinmaru has Sesshōmaru accompany him in order to kill Inuyasha. Inuyasha and Kagome entrust the newborn Moroha and the tincture to Hachiemon and confront the duo. Claiming that Inuyasha's Meido Zangetsuha is a power that is needed in the future, Sesshōmaru steals the Black Pearl from Inuyasha and seals both him and Kagome inside it instead of killing them.

Four years later, Zero learns where Towa and Setsuna are hidden and orders Homura to burn down the forest where they live, with Sesshōmaru unable to intervene. Hachi entrusts Moroha to the wolf-demon clan and Riku ends his narration, affirming that he can not reveal further for now.
