Requiem of the Villainess

In the world of the otome game Song of Walpurgis, the villainess Lillian Lancaster stands in the way of the heroine's quest for true love, preparing an array of devious traps with ravenous monsters in order to get the heroine crushed, cursed, kidnapped, or eaten.

However, while the otome game ended the heroine falling in love with Prince Luther, and the villainess punished by being married off to a wicked old aristocrat to become his slave, things are different this time around.

The game's plot has finished, but the story continues on. Refusing to accept the fate that has been heaped upon her, Lillian murders the aristocrat and feeds his blood to a demonic idol to summon Asmodeus, the Demon of Lust, allowing him to possess her body.

On a quest for revenge, Lillian sets out with Asmodeus to destroy the heroine once and for all- but to do so means to conquer the perilous challenges of her journey and confront her own wicked nature, making her reconsider if evil is truly the right path to walk. At the same time, memories of an old life begin to return to the villainess, conflicting her with the dilemma of what is reality and what is merely fantasy...
