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.

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.

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.

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.
