The sacred kingdom of Ellerald is at war with the endless hordes of wretched monsters known as Lustfiends. Keeping them at bay are the mighty warriors of the Holy Guard, led by their fearless commander Noein—but when the Holy Guard are sent away to stem a suspiciously well-coordinated invasion, the capital is terrorized nightly by the foulest of beasts. Underdefended, the heart of the kingdom is on the brink of ruin.
Desperate to save her people from suffering, Princess Cecily Ellerald makes a difficult decision. She forms a pact with the god-tree, Sephirot, granting Cecily the power to transform into a heavenly warrior capable of single-handedly curbing the lustfiend threat! Her divine powers as Eden's Ritter Lucifel are formidable, but costly, for the longer she uses them, the stronger her bodily urges become. Over the course of her adventure, Cecily must learn how to master her powers, lest her demonic foes should master her instead.
To make matters worse, an even greater foe lurks in the shadows... the vile order of the Xenobides, who plot to use Princess Cecily’s newfound powers against her and usurp her kingdom. Their tentacles are everywhere, and their army of monsters will push our heroine to her limits... in more ways than one! Will Cecily succeed in defending the kingdom—or will her dark desires get the better of her, and seduce her to succumb to utter ecstasy?
