The war with humanity ended in the demons' overwhelming victory, and the demon Valdy took the Saintess captive. His aim was to torment the arrogant Saintess, who had started the war against the demons based on supposed divine oracles, until she wept.

However, when he finally confronted the Saintess, ready to reduce her to a mere rag, she was already sitting with her knees drawn up, her eyes quite lifeless.

This is a heartwarming prisoner-of-war rom-com about a Saintess exhausted by a life of misfortune, and a demon who, finding the Saintess he'd intended to make bawl too pitiable, begins to encourage her instead.
