The series follows Elfina, a proud and petite guardian knight sworn to protect her kingdom. Initially a symbol of purity and strength, her resolve is tested when she's captured by demonic forces. Over the course of the series, she is subjected to a relentless series of debaucheries designed to break her spirit. The demons exploit her small, flat-chested body, engaging in brutal non-consensual encounters that push her to her absolute limits. She endures intense mind-breaking and corruption, her holy armor defiled as she's forced into increasingly depraved acts. Her cries of protest turn into moans of unwilling pleasure as her mind and body are thoroughly corrupted, transforming her from a holy knight into a fallen, pleasure-seeking slave for her captors, her womb filled repeatedly with demonic seed.
