Ep. 2: Setsuna confronts a vengeful snake-demon spirit while Towa protects demon-slayers from petrification.

Moroha questions Jyuubei about Bokusenou before joining Setsuna to locate a wise demon. They encounter a snake-demon spirit disguised as a nun, who seeks Setsuna’s waist-length hair to quell her bitterness over losing her true form. Towa arrives wearing mirrored sunglasses to shield demon-slayers from turning into statues. Setsuna then uses the ultimate power of Yukari no Tachikiri to sever both physical and immaterial entities. This act restores the destiny of the snake-demon and her human lover, a fisherman. The spirit finds peace, regains her original form, and returns to the sea. The Half-Demon Princesses depart on Takechiyo while Riku watches from afar, relieved that Towa is safe. He anticipates their next meeting, where Towa will wield a genuine weapon charged with immense demonic energy against the siblings.
