## Their Relationship

### Hanyo no Yashahime

**Inuyasha: Since Then**

**The Three Princesses**

When Moroha was in the mountains waiting for her next target to appear, she was confronted by group of yōkai taijiya, including Kohaku and his maternal nephew, due to the rumors of a yōkai rampaging through a nearby village. Just as Hisui was about to confront her, Kohaku stopped him and asked Moroha if she was after the real culprit, to which she confirmed, but was still prepared to attack them due to them having provoked her. Moroha then took out a shell compact containing a mysterious rouge with a red pearl at the center and was about to apply some on her lips, but was suddenly confronted by Setsuna. Moroha tells the other demon slayers that Setsuna is interesting for being a hanyo but was also one. Setsuna tells Moroha to be silent as she's dead.

Moroha clashes with Setsuna as she expresses a liking towards Setsuna's naginata, opining that the latter should have no qualms of surrendering it over to her if she bests Setsuna fairly in a fight. Hisui flies on Kirara towards Setsuna as he said he'll back her up. Setsuna tells Hisui there's no need. Moroha questions Setsuna if that's her name and calls her 'Setsuna-chan' as she'll be taking her weapon before they fight. As the two of them battled, Setsuna's right eye began to mysteriously glow, apparently reacting to Moraha's red pearl. It was then that the ōmukade Mistress Three-Eyes appeared from underground and attempted to obtain Setsuna and Moroha's pearls, which caused an abrupt end to the fight. Kohaku realizes that Mistress Three-Eyes was the one attacking the village before tells the others demon slayers to retreat. Mistress Three-Eyes demanded that Setsuna and Moroha give her the rainbow pearls as she goes after Setsuna. Hisui flies towards Setsuna, who is frozen, and grabs to pull her out of danger before flying away. Hisui asks Setsuna if she was okay. Setsuna snaps out of it before she gets on Kirara.

Moroha engaged Mistress Three-Eyes with her sword Kurikaramaru, but it was unable to cut her but pulls out her bow and arrows. Kohaku tells Hisui to go to another location, who follows the order. Moroha then uses Sacred Arrows: Tenkū no Yabusuma. as they had manage to strike Mistress Three-Eyes. Kohaku questions if those are sacred arrows before he realizes they are Arrows of Sealing then wonders how could Moroha have such spiritual powers. Moroha thinks she's defeated Mistress Three-Eyes until she starts moving. Mistress Three-Eyes telekinetically steal Moroha's pearl and swallowed it, thus increasing her power. Afterwards, Mistress Three-Eyes turned her attention towards Setsuna and attempted to claim her pearl as well. Kohaku tells Hisui to divert Mistress Three-Eyes to Kaede's village. Hisui complies as he Setsuna take off on Kirara with Mistress Three-Eyes. Moroha follows after Mistress Three-Eyes to get back her red Rainbow Pearl.

At night in the village, Kaede appears from her hut and sees Hisui and Setsuna on Kirara being chased by Mistress Three-Eyes, who demanded they give the rainbow pearl. Hisui tells Setsuna that he thinks they've come far enough. Setsuna tells Hisui she's decided to fight Mistress Three-Eyes. Hisui becomes surprised. Setsuna says since Mistress Three-Eyes was after the gold rainbow pearl in her right eye she'll use that to her advantage. Hisui calls out to Setsuna, who jumps to battle Mistress Three-Eyes. Setsuna tells Mistress Three-Eyes she won't let her get away. Mistress Three-Eyes charges at Setsuna, who uses Cyclone Burst. Setsuna tells Mistress Three-Eyes her name as those are her only words for her as she will die tonight.

As Mistress Three-Eyes and Setsuna are battling, Moroha interfered with her Crimson Dragon Wave. Moroha tells Setsuna she has claimed that Mistress Three-Eyes was her target from the start. Setsuna simply ignored Moroha and charged towards Mistress Three-Eyes, but was unable to kill her. Mistress Three-Eyes then restrained Setsuna and managed to steal her pearl and become much stronger. Moroha tells Setsuna to hold on as got her then calls her 'Setsu'. Setsuna tells Moroha to not call her that. As Mistress Three-Eyes was about to kill Setsuna, the Goshinboku near where they were fighting suddenly opened up a portal and transported them, as well as Moroha, to the Higurashi shrine in the modern era.

**The Dream Butterfly**

In the Feudal era, Kaede tells Kohaku, Hisui, and the other demon slayers that Setsuna is Sesshōmaru's daughter. Hisui becomes surprised as it would make Setsuna a hanyō and wonders that's the reason she's so powerful. Kaede explains 14 years ago Sesshōmaru came to the village and took his newborn twins with him and that was the last she saw of them until one day Setsuna came to her and told her that it was 'a rite of courage and cowardice'. In a flashback, Kaede was walking to her hut until she sees a 10 year old Setsuna, surprising her. Setsuna tells Kaede she'll be in her care for a while. Kohaku asks Kaede about the 'rite of courage and cowardice'. Kaede says a lion is said to push their cubs into the bottomless ravine, and raise only the ones strong enough to crawl back up on their own as it is known as the rite of courage and cowardice. Hisui wonders if that's what Sesshōmaru is doing to Setsuna. Kaede says it's possible though she can't say for certain. Kohaku says Sesshōmaru used to help him a lot back when he was a kid but even then it was difficult to understand his true intentions. Hisui tells Kaede she said twin and wonders if there's another child out there. Kaede wonders but being uninformed hanyōs as its very possible that she may have already killed the other out of hate. Hisui becomes surprised.

In the Feudal era, Kaede questions that Mistress Three-Eyes, Setsuna, and Moroha vanished near the Sacred Tree. Kohaku confirms it and asks Hisui to show Kaede. Hisui complies and explains he found this attached to the root of the Sacred Tree. Kaede realizes that's Root Head. Kohaku realizes as he knew he had seen it before. Kohaku tells Hisui that Root Head is a demon they've slain back when he was a baby. Kaede realizes that if Root Head really did attach itself to the Sacred Tree then this could be a problem. Hisui questions if a demon's tree root can absorb the powers of it's host like the Hitōkon. Kaede agrees and explains attached itself to the Tree of Ages of all things. Hisui wonders about the Tree of Ages. Kohaku explains he's heard of the Sacred Tree being called the Tree of Ages but wonders why. Kaede asks Kohaku does he know about the Bone Eater's Well. Kohaku asks Kaede if she was referring to the well Inuyasha and Kagome used to travel through. Kaede says it's been 15 years since it's become defunct but according to Kagome that well had the power to travel across time. Kohaku questions about travelling across time. Kaede explains Kagome and Inuyasha simply described it as going to 'the other world'. Hisui wonders about the other world. Kaede explains that the well was made using wood from the Tree of Ages and if Root Head was attached to the Tree of Ages then it may have absorbed the Tree of Ages' ability to cross into the other world. Kohaku and Hisui become shocked. Kohaku realized Setsuna and the others may have gone to. Kaede says to Tokyo the village Kagome originally came from. Hisui asks Kaede can Setsuna and Moroha even come back from a place like that. Kaede tells Hisui she's afraid it would be no easy task.

**The Gateway to the Past**

In the Feudal Era, Kaede senses something before she steps out from her hut to see the rainbow beam. Hisui goes towards Kaede with Kirara as he calls out to her about the light. Kaede agrees with Hisui as it's the light from the Sacred Tree. Hisui wonders to Kaede if Setsuna could be returning here. Kaede tells Hisui that may be so. Hisui calls out to Kirara, who transforms, before flies on her. Hisui tells Kaede that he'll notify Kohaku as he leaves.

A Rainbow Corridor opens up as Towa, Setsuna, and Moroha are sucked in and exit as they arrived in the Feudal Era. The Sacred Tree stops glowing. Setsuna's violin and Moroha's bag falls on Moroha, surprising Towa and Setsuna. Setsuna takes her violin. Towa asks Moroha if she's all good. Moroha does answer. Towa realizes this is the Feudal Era. Kohaku and Hisui calls out to Setsuna. Towa, Setsuna, and Moroha look to see Kohaku, Hisui, Kaede, and Kirara arrive. Kohaku tells Setsuna that he's glad she's safe. Setsuna tells Kohaku and Hisui that she has managed to return. Kohaku becomes relieved at Setsuna. Kaede says she can't sense Root Head's demon energy and wonders what happened. Moroha caresses her bag before she tells Kaede that she, Towa, and Setsuna defeated Root Head. Kaede becomes surprised as she wonders if that's true. Towa becomes shocked and thinks to herself and realizes that's right. Towa looks at the Sacred Tree and thinks to herself that if they defeated Root Head and how are they getting back to the Modern Era.
