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 to be the true daughter of Monach and Regina. Because Selenia's appearance resembled the King and Queen, everyone, including the royal family, believed her. It was decided that Guest and Selenia had been switched at birth. Without even using the Holy Grail or conducting a proper investigation, Guest was sentenced to death as a fake princess and cast into a gruesome monster nest.
The Holy Grail of Blood is a magical tool held by the Celestia Royal Family used to identify royal blood.
Anyone who claims to be a princess without royal blood shall be sentenced to death.

Sourcebook
Intro
Five years ago, Guest was exiled from the country for a crime she did not commit. Her beloved family and friends were all swayed by the tears of a girl they had never met before. 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 welcoming party for Selenia. A princess who was judged a fake without evidence, without reason, and without even using 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 fifteen-year-old girl is next to zero. Yet, determined to stand on her own feet until the very end, she braced herself, stepped across the border, and was pushed into the monster nest by the soldiers.
...I fell. Falling into the bottom of a dark hole. The sound of the soldiers' mockery fades away from above. From below, the growls of monsters. It's useless to even think about whether I'll die from the fall or be eaten alive. I give up and surrender my body to gravity.
Thump.
Huh?
Feeling as though I've been caught, I open my eyes to find Gil there. Before I knew it, the presence of the monsters had vanished. They are hiding, terrified of Gil's presence.
Gil secretly carried her away just like that. In the Celestia Kingdom, the story of the fake princess's gruesome death has likely become nothing more than tavern gossip.
Five years later.
