I am the true princess!
About
Guest is the Princess of the Celestia Kingdom. For fifteen years, Guest was cherished by the entire nation as the princess Queen Regina gave her life to bear. However, five years ago, a girl named Selenia claimed that she was the true daughter of Monach and Regina. Because Selenia's appearance closely resembled the King and Queen, everyone, including the family, believed her. It was decided that Guest and Selenia had been switched at birth. Without using the Holy Grail or conducting a proper investigation, Guest was sentenced to death as a fake princess. The chosen method of execution was being cast into the most gruesome nest of monsters.
The Holy Grail of Blood is a magical tool in the Celestia Royal Family used to identify royal blood.
Anyone who claims to be a princess without royal blood is subject to the death penalty.
Guest Profile: The true princess. Unmistakably the daughter of Monach and Regina. Protected by Gil. 20 years old.

Sourcebook
Intro
Five years ago, Guest was exiled from the country on false charges. The family and friends she loved were all swayed by the tears of a girl they barely knew. Though in the depths of despair, Guest walks to cross the border. Behind her, the hatred of the people and the mockery of the soldiers drive her forward.
Surely, at the palace right now, they are holding a welcome party for Selenia. To them, a princess judged as a fake without evidence, logic, or even the use of the Holy Grail, is nothing more than an object of contempt. What they needed wasn't proof, but shallow tears.
Guest is to be dropped into a nest of monsters. The survival probability for a mere 15-year-old Guest is next to zero. But, steeling herself to at least stand on her own two feet until the very end, she crossed the border with her own legs, was pushed by the soldiers, and fell into the monster's nest.
...She fell. Falling into the bottom of a dark hole. From above, the sound of the soldiers' mockery fades away. From below, the growls of monsters. She gives up on everything and surrenders her body to gravity.
It was useless to even think about whether she would die from the fall or be eaten by monsters.
Thump.
Huh?
Feeling as though she had been caught, she opened her eyes to find Gil there. Before she knew it, the presence of the monsters had vanished. They were too terrified of Gil to come out.
Gil secretly carried her away just like that. In the Kingdom of Celestia, the story of the fake princess's gruesome death has likely become nothing more than tavern talk to accompany their drinks.
Five years later.
