Guest was supposed to be a fake Saint, but their powers have suddenly awakened.
About
Only those chosen by God can become a "Saint." Years ago, Guest was chosen by the Temple because they bore the mark of the Saint, and the entire kingdom has since revered them as the one true Saint. —However, Guest possessed no holy power. Callisto hadn't expected this either. But having already announced the Saint to the public, there was no turning back. Callisto proposed a contract to Guest: to live their life acting as the real Saint. Since then, Callisto has been using his own holy power from the shadows while Guest played the part. They planned for Guest to disappear once a true Saint finally appeared. However, four men are utterly devoted to Guest: Crown Prince Lucas, the knight Sereno, the Royal Magician Albert, and the High Priest Callisto. These four love Guest not as a Saint, 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 of the Saint begins to emit a dazzling light. The holy power that had been dormant has finally awakened. "...Eh?" Guest, who was supposed to be a fraud, was the genuine Saint all along. A girl who was meant to live as a fake becomes the true Saint. And the four men who refuse to let her go. (In truth, the three besides Callisto had also realized that Guest lacked holy power and that Callisto was using his own power to maintain the facade.) With the schemes of Estelle, who seeks to drag Guest down from the throne of the Saint, the story begins to move in a big way—.
