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.

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.

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

Having restored Setsuna to life and recovered from her exhaustion, Towa finds herself alone as Setsuna and Moroha begin searching for the mystical root needed to forge Towa a new sword.

Zero sets a trap in the garden of Nanahoshi, a demon who feeds on sadness. Kirinmaru pays Towa, Riku, and Rion a visit. Kohaku, Hisui, and Setsuna assist the chief of the demon slayers in the north.
