Episode 18 (Hanyō no Yashahime)

"Sesshōmaru and Kirinmaru" is the eighteenth episode of Hanyō no Yashahime.

Summary
Towa and Setsuna find Moroha, and the cousins get ready to annihilate Konton and Tōtetsu once and for all. They manage to succeed, and Lord Kirinmaru finally appears before the Half-Demon Princesses, as does Towa and Setsuna's own father Sesshōmaru. Do have they have the stomach to go through with what the Sacred Tree of Ages has requested of them to save all of time, even if its taking down Sesshōmaru?

Plot
Towa and Setsuna fight Konton, who tells the twins that the Rainbow Pearls they possess will only spell disaster as they are fragments of an even greater demonic power that was divided by Zero. With the eight-field spell undone, they help Moroha swiftly overpower Tōtetsu, who flees to Lord Kirinmaru's ship to lure them to be killed by Kirinmaru. Kirinmaru finally appears before the three as he drives Tōtetsu off. With Kirinmaru unperceptive to Towa's attempts to solve matters peacefully and return Setsuna's dreams, the three half-demons fight Kirinmaru but are quickly outmatched as Moroha is knocked out after failing to overcome Lord Kirinmaru with the strength of her demonic blood, and Towa and Setsuna subsequently being easily defeated by the beast king.

Sesshōmaru arrives and fights Lord Kirinmaru to protect his teenage twin daughters, the shockwaves of their clash knocking out Towa and Setsuna and shaking all of Heaven and Earth, as Kirinmaru decides to spare Towa and Setsuna but reminds Sesshōmaru they still need to work together. Sesshōmaru subsequently leaving with Jaken. This leaves Towa, Setsuna and Moroha confused, as Towa especially wonders what her father's true motives are. Moroha tries to get the essence of the Sacred Tree of Ages to emerge, but is unsuccessful as the impossible time-surpassing entity shows us Towa and Setsuna's beautiful teenage mother in her ceaseless slumber within it as the Dream Butterfly sprinkles the memories and dreams of youngest twin daughter onto her.

Trivia

 * The Half-Demon Princesses encounter Lord Kirinmaru for the first time. Towa and Setsuna also meet their father Sesshōmaru as he appears to protect them from Kirinmaru.
 * This is Sesshomaru and Jaken's debut in the present.
 * Even though Sesshōmaru was stated to have surpassed his late father when he instinctively created Bakusaiga from his own body, Kirinmaru proved able to fight equally with him, despite him being stated to only be equal to Tōga in strength. As the two are formidable beast kings, their battle is such that all of the Earth and Heavens themselves quake whenever they clash as they are naturally equally matched.
 * The connection between Kirinmaru and the Dream Butterfly is that if Lord Kirinmaru is slain, then the Dream Butterfly will disappear.
 * Konton dies in this episode, making Tōtetsu the only remaining member of the Shikyō.
 * The Rainbow Pearls are revealed to been, in fact, seven fragments of an ancient and even greater demonic power that was divided by none other than Zero, for being way too dangerous to ever use to its fullest potential. This ancient supreme demonic power seems to be coveted secretly by Riku, as he has expressed a desire to attain all seven pearled fragments for himself.
 * Jaken expresses how Towa and Setsuna have grown, who naturally do not know he their father's longtime most devoted vassal.
 * Riku takes the blue Rainbow Pearl from Konton's headless corpse, further strengthening his natural abilities once adding it the purple and green Pearls had attained from Kyuki and Juybei. This leaves only the orange one Totetsu had just swallowed, and the red, gold and silver pearls in the possession of the Half-Demon Princesses, in order for an even greater demonic power to be unleashed on the world once all seven merge into one.
 * Towa's attempt to cut through Lord Kirinmaru's vortex of demonic energy is what Tetsusiaga's Dragon-Scaled ability does by revealing the opponent's demonic energy in the form of a swirling vortex, enabling Inuyasha to cut through it and gravely weaken his enemy.
 * Whenever Lord Kirinmaru and Sesshomaru the greatest beast kings, clash, the very Earth and Heavens themselves are disrupted; similar to whenever Raava the mighty Spirit of Light and Peace (before becoming the Avatar Spirit once she had permanently merged with Wan) clashed with Vaatu, the Spirit of Darkness and Chaos, every ten millennia in their battle for the destiny of both the spirit and physical worlds.

Errors

 * When Moroha reaches Towa and Setsuna, the Kikujūmonji was lying on the ground. However when Moroha was shaking Towa awake, the sword was shown back in its sheath.
