Episode 15 (Hanyō no Yashahime)

"Farewell Under the Lunar Eclipse" is the fifteenth episode of Hanyō 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 Hōsenki 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 beings that are neither human nor demon who would destroy Lord Kirinmaru.

Plot
Riku reveals that 18 years before back in the year 1501, he had the Yōkai jeweler Hōsenki II to create the Black Rainbow Pearl using Inuyasha's mother's rouge, which contains her tears of grief for her husband's death, and can create a path to his father's resting place. Hōsenki II then gives the pearl and the rouge to Inuyasha and Kagome respectively, with Inuyasha putting the Pearl into his right eye for safekeeping. Four years later, Rin gives birth to the twin hanyō daughters, naming them 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 know about them.

In response, Sesshōmaru takes the newborn Towa and Setsuna with him. Joka attacks him to kill the babies and Sesshōmaru 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 a half-demon who can surpass time, 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 Meidō Zangetsuha ability is needed in the future, Sesshōmaru steals the Black Pearl from Inuyasha and seals both him and Kagome, trapping them within Tōga's graveyard ever since.

Hachi entrusts Moroha to Kōga and Ayame of the Wolf Demon Tribe, and four years later Zero learns where Towa and Setsuna are hidden via the dream-gazing spell and orders Homura to burn down the forest where they live, with Sesshōmaru refusing to intervene. In the end, Riku ends his narration affirming that he cannot reveal further for now.

Trivia

 * This marks the second flashback narrative and prologue of Hanyō no Yashahime.
 * The half-demon twins are all born during a lunar eclipse as was Inuyasha, as seen in the Swords of Supreme Conquest movie.
 * The lunar eclipse (1296 + 209 = 1505) that it happens for same birth of the dog half-demons.
 * The flashback of Sō’unga appear as Tōga with Kirinmaru stops the Grim Comet.
 * It is revealed that Riku had once been in possession of the green Rainbow Pearl as well as the blue one; the green Pearl's current possessor is Jyūbei.
 * Lady Joka's desire for vengeance on Sesshōmaru was due to him slicing off her arms and attaining the gold and silver Rainbow Pearls from her.
 * Shippō and Miroku do not appear in this flashback narrative as they had in the premiere.
 * Izayoi's rouge first appear in Episode 147 in flashbacks of young Kaede about her sister Kikyō; Inuyasha gave it to Kikyō as a gift but it was destroyed by Naraku in Episode 148. Hōsenki II somehow had its fragments recovered and reassembled albeit with difficulty.
 * It is revealed that powerful mystical pearls are created from the tears of deep sorrow and grief from either humans or demons; the late Lady Izayoi having made the Black Pearl, and Zero the gold and silver Rainbow Pearls.
 * Inuyasha and Kagome's current whereabouts are revealed- the demon graveyard of Tōga and Hōsenki I.
 * It is confirmed that Rin is Towa and Setsuna's mother.
 * While not stated, Rin was likely put in her slumber shortly after the forest fire; which would match up with the Yume no Kochō stealing Setsuna's sleep and memory.
 * Hisui's height when Rin gave birth to the twins can be considered erroneous, as it seemed way shorter than his own sisters' and not the same as Towa and Setsuna's during the forest fire.
 * The prophecy of the defeat and demise of Zero and Lord Kirinmaru is similar to the 1997 Disney film Hercules that the Fates' future vision that Hercules will defeat Hades. As well as the prophecy depicting Harry Potter ultimately ending Lord Voldemort from the Harry Potter novels.
 * Zero and Kirinmaru tries to kill Towa, Setsuna, and Moroha as babies (which Joka has sent and failed to kill the twin babies) just like Hades sent Pain and Panic to kidnap baby Hercules to turn him to mortal and kill him. Just as Lord Voldemort had attempted to destroy Harry Potter at the mere age of one.
