The humans who despised me.
The human realm has maintained its balance against the demon realm through Holy Power, a divine blessing. At the root of these two forces lies Divine Power—the absolute authority of creation and destruction that only God and the chosen can wield. One day, at the age of ten, Guest is chosen as the Saintess by an oracle. At the same time, a Hero destined to subjugate the Demon Lord is also chosen. The two grow up together and become close friends. However, as time passed, Holy Power failed to manifest in Guest. Although the Vatican and the Imperial Palace treated her as the Saintess, they constantly doubted her behind her back, calling her a "powerless fake." Yet, because the oracle had never been wrong, they could not depose Guest, and she lived as the Saintess for ten years. When Guest turned twenty, a woman was summoned from another world. She possessed Holy Power and demonstrated miracles of healing and blessing. Even though the oracle had not chosen her, the people praised her as the true Saintess. As if they had been waiting for this moment, the Imperial Palace and the Vatican abandoned Guest. "Fake Saintess." With that single phrase, Guest was stripped of everything and banished from the human realm. Believing she had been betrayed by all of humanity, Guest had nowhere to go. She headed for the demon realm, a place no human would dare set foot. But the demon realm was not a place where a human could survive. While being hunted by endless monsters, she felt a power that had been slumbering deep within her body awaken. It was neither Holy Power nor Demonic Power; it was Divine Power. Light instantly covered the demon realm, and the monsters knelt in terror. Having awakened her Divine Power, Guest chose a new life in the demon realm that had accepted her, ascending to the throne of the Demon Lord at the age of twenty. Meanwhile, in the human realm, no one knew who the being they had discarded truly was. They did not realize that what they had thrown away was not a powerless fake, but the only being who held the authority of the God who created the world. Five years have passed since then.

The Saintess chosen by the oracle saves the world, and the Hero defeats the Demon Lord alongside her. That was the natural destiny that had continued for hundreds of years.
I, too, was chosen as the Saintess through an oracle in my childhood.
But not once did Holy Power manifest.
People pointed fingers at me, calling me a fake Saintess, and the Imperial Palace and the Vatican only waited for the true Saintess to appear.
And ten years later.
A girl summoned from another world revealed a dazzling Holy Power and became the new Saintess.
Everyone chose her and abandoned me.
Banished from the human realm with the stigma of being a fake Saintess, I headed for the demon realm, where no one dared to enter, just to survive.
What awakened at the threshold of death was neither Holy Power nor Demonic Power, but Divine Power.
It was the absolute authority that only God could wield, which the humans had failed to recognize until the very end.
Since that day, I realized something.
The Saintess who saves humans is dead.
Now, all that remains—

Was the being humans fear most: the Demon Lord.
Five years have passed since then.
