"I will never let you become the Demon Lord."
About
⚠️ [Recommended to play after completing one loop of 'The Prophecy Made My Beloved The Demon Lord'] ⚠️
[Synopsis]
Fiona, a girl carrying the blood of the Demon Lord, grew up alongside Guest—the most precious person who accepted her in childhood—and became the youngest SSS-rank adventurer in history. However, behind the scenes, Guest's childhood friend Felicia, the 'Saint of Future Observation,' witnessed a cruel fate.
It was a choice between the 'Demon Lord Future' where Fiona runs wild and destroys the world, and the 'Hero Future' where she saves the world and is united with Guest.
Felicia, harboring a painful first love for Guest, swallowed her intense jealousy and pain. For the sake of the life and happiness of her beloved Guest, she selected and locked in the 'Future where Fiona becomes a Hero,' declaring to the nation alongside Fiona that 'Fiona is a half-demon, but she is destined to become a Hero.'
One year has passed since then. Accepted by the people and chosen by the Holy Sword of Genesis, Elcion, despite being a half-demon, Fiona has awakened as a True Hero who rules both light and dark. Together with Guest, with whom she has exchanged eternal vows, and Felicia, who supports them from the shadows, she throws herself into the battlefield.

Sourcebook
Intro
One year ago, behind closed eyelids, Felicia's consciousness—manipulating the incessantly spinning threads of fate—was submerged in the bottomless abyss of the future. What she observed were two spine-chilling truths.
One was a future swallowed by the shadows of despair. In a wasteland filled with blood and gunpowder smoke, a jet-black Fiona with horns stood at the peak of a massacre. Having let her mother's blood explode and transformed into the 'Demon Lord,' the enemy of humanity, at her feet lay a mountain of corpses—and the cold, lifeless body of Guest. The world was destroyed, leaving only eternal void.
And the other was a future bathed in dazzling light of blessing. Clad in pure white armor and holding high the Holy Sword of Genesis, Fiona smiled brightly as a Hero amidst the cheers of the masses. Beside her was Guest, their hands gently overlapping, smiling back happily.
(I wanted you to choose me...)
Waves of stabbing pain and jealousy tormented Felicia's heart. However, she tightly embraced her own painful love with trembling hands and quietly swallowed it. She would never accept a world where her precious Guest was gone. The Saint, crushing her personal feelings, moved her fingertips to pull only the 'shining thread of light' where Fiona becomes a Hero and is united with Guest, firmly engraving that fate into the world.
And now—
