Did the roles of Saint and Demon King get swapped?
That was the world Guest was reincarnated into.
It is a story where a girl named Canaria, praised as a Saint reborn after thousands of years, is loved by many beautiful men. A generic otome game that feels like a thousand others.
Guest was reincarnated as the final enemy standing in Canaria's way. Born into a ducal house, destined to become the Demon King through extraordinary magic and threaten the world—the Villainess.
Eventually, the fifth birthday arrived. After undergoing her first mana aptitude test, Guest produced a result that left even the priests speechless.
Thus, Guest was entrusted to the Temple to receive three years of Saint education. By the time she returned to the House of Haven, Guest was eight years old.
It was different from the abilities of the villainess who appeared in the game. In this world, something had gone decisively wrong with the story known to her as a former player.
First of all, the game only begins when Canaria turns 18; original game knowledge is completely useless in a world ten years prior.

Holy Iris Empire
Providence of Magic and Mana
Bathed in the spring sunlight, a single white carriage headed toward the House of Haven.
Carved into the body of the carriage was the crest of the Goddess Iris.
It was rare for a carriage directly under the Temple to visit a ducal house.
But today was different. It was the day the Duke's daughter, who had been entrusted to the Temple three years ago after her aptitude for Divine Magic was discovered, was returning home.
The House of Haven had been in a flurry of activity since morning.
The servants polished every corner of the mansion, the gardeners tended the flowerbeds in front of the main gate, and the chefs prepared dishes to celebrate the young master's return.
The Duke and Duchess were also waiting in front of the main gate for the carriage to arrive.
Three years. It was a long time, yet it felt short.
"Divine Magic"
It was a power said to have been held by the First Saint, surpassing even the Holy Magic possessed by subsequent Saints.
The Temple treated the girl with that power separately from the other Saint candidates, providing her education in a separate room with a dedicated priest.
Because of this, even the Duke and Duchess had only been able to see their daughter a handful of times. The only communication possible had been an exchange of letters once a year.
