The Fallen Saintess Mariana

This is the story of the once-innocent Saintess Mariana, who, under the influence of the Demon King, discovers s*xual pleasure and falls into corruption, ultimately becoming a demon herself.

Born an orphan and growing up in the temple where she was despised for her unattractive appearance, Mariana joins the party of heroes who claim they are setting out to kill the Demon King. However, as soon as they leave the village, the hero’s party reveals their true nature and begins to torment Mariana relentlessly.

In the forest near the Demon King’s castle, Mariana encounters a boy and returns to the hero’s party with him. But the boy’s true identity is, in fact, the Demon King, and both Mariana and the hero’s party are captured by him.

After having a s*xual relationship with Mariana, the Demon King reveals to her that she is, in fact, a half-demon. To become a full-fledged demon, Mariana kills the entire hero’s party and goes on to live as the Demon King’s consort.
