**The Three Princesses**

As Setsuna and Moroha 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 and 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 Gold Rainbow 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.

Later that night, Towa and Mei look at the Sacred Tree. Towa picks up a familiar scent from the Sacred Tree. Mei calls out to Towa. Towa calls out to Mei before she quickly moves them to Grandpa and Ms. Higurashi. A portal opens up. Mei wonders what it was. Towa becomes familiar with a scent. The portal reveals Mistress Three-Eyes, along with a teenage Setsuna and Moroha. Towa realizes the unbelievable bright place from her memories and this smell was Setsuna as she calls out to her, her silver rainbow pearl glowing. Setsuna wonders who's calling her name. Moroha says she feels so weak and wonders if it's because she crossed through the rainbow corridor. Mistress Three-Eyes becomes happy that she senses the silver rainbow pearl was nearby as each of her 3 eyes will have a rainbow pearl. Upon seeing Setsuna in trouble, Towa runs in to save her from Mistress Three-Eyes with the Kikujūmonji. However, the blade of Towa's katana ends up breaking upon contact of Mistress Three-Eyes's skin when she tries to slash her, much to Towa's shock.

**The Dream Butterfly**

In the modern era, Towa quickly dodges Mistress Three-Eyes's attack. The large broken Kikujūmonji piece lands near Moroha. Towa becomes shocked that the Kikujūmonji broke. Moroha tells Towa that the Kikujūmonji is obviously a fake as the blade pattern's completely different. Towa becomes surprised the Kikujūmonji was a fake. Mistress Three-Eyes demands Towa to give her the silver Rainbow Pearl as she releases Setsuna, who wonders why her body won't move. Towa wonders what Mistress Three-Eyes talking about. Mistress Three-Eyes demands Towa to give her the silver Rainbow Pearl. Angered that Mistress Three-Eyes broke her Kikujūmonji and the hurting of Setsuna sister, Towa activates her demon powers for the first time by transforming the broken katana into a Demon Energy Blade with silver Rainbow Pearl, shocking both Setsuna and Moroha. Towa impales Mistress Three-Eyes in the chest. Moroha couldn't believe Towa created a demon energy blade with her own power. Mistress Three-Eyes fell to the ground in pain. Towa wonders if she did that. Moroha asks Towa why was she doing as she has to hurry up and finish Mistress Three-Eyes off. Towa tells Moroha she doesn't think that's possible. Moroha tells Towa this is not the time to hesitate. Setsuna begins to get up. Mei calls out to Towa. Mistress Three-Eyes charges at Grandpa, Ms. Higurashi, and Mei, shocking Towa. Moroha tells Towa does she see what she means and if she doesn't hurry they'll get eaten. Towa calls out to Mei.

Setsuna finishes Mistress Three-Eyes off with her Kanemitsu no Tomoe as she tells her it's nothing personal. Mei tells Setsuna 'thank you' for saving them. Ms. Higurashi tells Setsuna for saving them. Setsuna tells Ms. Higurashi and Mei there's no need to thank her as she steps back a bit. Towa approaches Setsuna as she tells her that she's sorry. Setsuna asks Towa how does she know her name. Towa becomes shocked. Setsuna asks Towa who was she. Mistress Three-Eyes's body disappears, leaving only her skeleton. Towa asks Setsuna doesn't she remember her as it's her and she used to call her 'Sis'. Moroha approaches Towa and Setsuna as she says that was horrible but was happy she can finally move her body. Setsuna and Moroha recover their gold and red Rainbow Pearls. Towa wonders what are they before her silver Rainbow Pearl glows with the others. Grandpa Higurashi says this kind of nostalgic. Ms. Higurashi agrees as it reminds her of the times Inuyasha would could to visit Kagome. Grandpa agrees. Towa smiles warmingly at Setsuna. Moroha asks Setsuna she doesn't mind if she claims Mistress Three-Eyes' skull as a trophy. Setsuna tells Moroha to do as she wished. Moroha complies and wonders about the trip they're having as she looks around to that night in the modern era is as bright as day.

Setsuna tells Towa that's because she was. Moroha tells Towa and Setsuna to cut it out. Moroha tells Setsuna to stop acting like a kid and wonders what's the harm in letting Towa near her, using Mistress Three-Eyes' head.

**The Gateway to the Past**

Moroha tells Setsuna that Root Head looked pretty bored so she asked it some questions and then it wouldn't stop talking and they can get back to the other world by negotiating with Root Head. Setsuna tells Moroha that she suppose they could try it and asks about the bag.

Moroha tells Setsuna it's just a few things that they'll be able to over in the Feudal Era. A history book falls out of Moroha's hands as she wonders what it is but brushes it off and places it along with other items back in the bag then rummages through. Moroha tells Setsuna that she'll use Mistress Three-Eyes' head and Hitōkon's corpse will be able to buy her lunch. Setsuna become annoyed. Moroha rummages more in the bag as sees what else is in the bag.
