On the night of the new moon, Riku pays Towa a visit to chat. Unfortunately, he’s not the only one planning to drop by.

Setsuna and Towa hire Moroha to help slay Zero. The trio successfully track Zero down, but Riku stands in their way.

The truth behind the night that sealed the fate of Towa, Setsuna, and Moroha’s parents is finally revealed.

In the present day, a demon emerges through the Sacred Tree at Higurashi Shrine with Setsuna, Towa’s twin, and the bounty hunter Moroha in tow. Towa, Setsuna, and Moroha struggle to battle the demon, whose powers have been strengthened with two Rainbow Pearls, but seeing Setsuna in trouble awakens Towa’s latent demon powers.

When a demon begins to devour virtuous monks and Shinto priests in the region, Hisui is assigned to guard his father, Miroku, who has been undergoing harsh training for the past two years.

Towa and Setsuna set off to slay Homura, an evil mountain god who has abducted a beautiful maiden. The twins learn that Homura was involved in the forest fire that separated them.

Moroha once had a master named Yawaragi, who was keeping a life-threatening secret. In order to resolve the secret and protect her pupil, Yawaragi made an agreement with Jyubei.

Konton learns of the origins of the Rainbow Pearl and the connection between Kirinmaru and the Dream Butterfly. He summons an ogre to attack the Half-Demon Princesses.

Setsuna opens up to Towa about the hidden village for half-demons where she was raised for most of her childhood.

Zero removes the seal that Miroku placed on Setsuna to suppress her demon powers, awakening the latent demon blood within.

Wanting to prove his strength, Kirinmaru faces off against Sesshomaru. Towa summons the Tenseiga. Shippo waits for Inuyasha and the others at Gozu and Mezu’s gate.

Towa decides to return to the feudal era to help Setsuna regain her memories. The trio enter the corridor leading to the feudal era, but within it awaits the spirit of a certain priestess.

Safely back in the feudal era, Moroha heads to the corpse dealer to claim her bounty. Meanwhile, Towa and Setsuna take on a request to slay Jakotsumaru, a boy who has been extracting bones from humans and beasts in order to revive his father, the demon beast Tokotsu.

On her way to search for the Dream Butterfly, Towa meets a strange young man named Riku. Towa offers him an apple, and in thanks, Riku presents her with the genuine Kikujumonji sword.

The demon Nikosen was a sage before evil consumed his soul. Konton orders him to kill the Half-Demon Princesses. Towa struggles as her demon powers fade and she turns into a human.

Travelers are going missing one after another. Towa, Setsuna, and Moroha head to the northern mountains to crack the case, but instead they find a village completely overrun by ghost cats!

Moroha accepts a job to slay Konton, a member of the Four Perils said to have defeated Meioju, a demon beast with the ultimate armored shell.

The Half-Demon Princesses are tasked with slaying Kinka and Ginka, conjoined twins of the Ka Demon Tribe whose battles for dominance have been wreaking havoc everywhere.

Konton devises a plan to destroy the Half-Demon Princesses. Riku offers to help him out. The three girls are lured into a ravine and fall right into Konton’s trap.

The deputy shogun’s daughter Aiya offers to employ the demon slayers if they win in a battle against the bounty hunters.

Inside the Black Pearl, Moroha is finally reunited with her parents, Inuyasha and Kagome. Inuyasha begins to see a way out of the Black Pearl. Meanwhile, Kirinmaru’s attack leaves Sesshomaru gravely injured.

In the present day, Osamu Kirin sees the Grim Comet approaching. Meanwhile, in the feudal era, Towa’s life is in danger after she uses her Zanseiken. The Spirit of the Tree of Ages orders the half-demon princesses to go destroy the Grim Comet.

To destroy the Grim Comet, Towa, Moroha, and Setsuna must travel to the present day using the Windmill of Time, but Meidomaru stands in their way. Kirinmaru takes Rion and tries to travel across time by force.

Inuyasha and the others have their hands full with the evil spirits pouring out of the burning Windmill of Time. The three girls and Osamu Kirin try to stop the Grim Comet from falling to the earth.

Osamu Kirin brings the Grim Comet to the feudal era. He convinces Rion that they are both hoping for the same world and promises to make it a reality. Meanwhile, Towa, Setsuna, and Moroha are stuck in the present day.
