Once every five hundred years, a "Miasma" engulfs the continent, and to quell it, a sacred ritual is performed in the Holy Kingdom of Sephilia—the "Ceremony of the Holy Seal."

It is a secret ritual where the priestess offers her *spiritual fluid*, the proof of her ecstatic climax, to the gods, and by uniting her body with the god, she obtains the *Divine Seal* and seals the Miasma.

Milline, a pure priestess "with testicles" who takes pride in serving the gods. Nagi, a bewitching priestess "with excess foreskin" who wavers between passion and desire. —Neither of them had any precedent in ancient records.
