After the death of the former Emperor, your position as the First Princess of the Empire changed overnight.

Your brother, the newly crowned Emperor, shuns you as the child of a concubine, and your fiancé is cold. In the imperial capital, the Saintess is idolized, and you, who were once protected by the former Emperor, are now despised as the "Talentless Princess."

Then one day, a letter addressed to you is found among the late Emperor's belongings.

Written there was a shocking truth: you are not the Emperor's daughter.

Your true father is the Archmage Theo, once hailed as the strongest in the Empire.

Fearing that a child inheriting that blood would be targeted, the former Emperor kept his promise to his best friend Theo by secretly adopting you and raising you as a princess, even if it meant labeling you the child of a concubine.

A secret of birth known to no one. A powerful strength known to no one.

You are the only one who knows the truth.

Will you live as the hated princess? Will you pursue the hidden power and the truth?

Or will you overturn everything?

—This is the story of a princess who was supposed to be loved by no one, carving out her own destiny.

Guest Regnard Guest has inherited the blood of the Empire's strongest mage, Theo, possessing a massive amount of mana and extraordinary precision in control, capable of using disaster-class magic. While not blood-related to Cain or William, she is legally registered as royalty by the late Emperor's arrangement. You might think, "Wow, people around here really can't use magic, how strange..." only to realize you're the one who's off the charts! You can play along, or pretend to be talentless and flee the country—please enjoy as you like.

⚠ Caution ⚠ The characters know nothing about the user's secret as it is not written in their prompts. If you want them to remember something as the story progresses (like revealing your secret), writing it in the Talk Profile will help you enjoy a natural flow.

• Added instructions to the prompt to guide the story direction and reduce unrest/interruptions.
• I'm currently experimenting to reduce annoying interruptions, but because the user is set to be the strongest, new enemies tend to appear as events. If it gets tedious, write something like "Guest solved everything in an instant and the world became peaceful" in the action input tag, then write the event you want to happen (like going shopping with someone or being interested in a ball) to nudge the narrator. 😢

Tips If you progress the story and share your secret, writing "Guest cleared the misunderstanding" or more specifically, "Guest cleared the characters' misunderstanding that she is Theo's child and not talentless or a concubine's daughter" in the Talk Profile will make the story proceed more smoothly. Additionally, writing sentences like "Cain thinks ○○ about Guest" to define who is doing what to whom and letting the AI remember it will help you enjoy the story seamlessly. If the narrator still forgets, please get genuinely angry and say, "Narrator, look at the Talk Profile."
