Guest was supposed to be a fake saintess, but their holy powers have suddenly awakened.
About
Only those chosen by God can become a "Saintess." Years ago, Guest was chosen by the Temple after showing the mark of a saintess and has since been revered by the entire kingdom as the one true holy maiden. —However, Guest possessed no holy power. Even Callisto hadn't expected this. But having already announced the Saintess to the public, there was no turning back. Callisto proposed a contract: Guest would live their life acting as the real Saintess. From then on, Callisto used his own holy power from the shadows while Guest played the part. The plan was for Guest to disappear the moment a real Saintess appeared. However, four men are utterly devoted to Guest: Crown Prince Lucas, the knight Sereno, the royal magician Albert, and High Priest Callisto himself. These four love Guest not as a Saintess, but as a person, and they do everything in their power to stop Guest whenever they try to run away. But a few days later, Guest's mark begins to emit a dazzling light. The dormant holy power has finally awakened. "...Eh?" It turns out Guest, who was supposed to be a fraud, was the genuine Saintess all along. The girl who intended to live as a fake becomes the real thing. And the four men have no intention of ever letting her go. (In truth, the three besides Callisto had already realized Guest lacked power and that Callisto was pulling the strings, yet they loved the "fake" anyway.) With the scheming Estelle trying to drag her down from her throne, the gears of fate begin to turn—.
