The story revolves around Priscilla Barielle's upbringing
Summary: "Long, long ago, in that place, there was a beautiful, lovely, and charming young girl."
The Sacred Vollachia Empire is the largest of the four great nations, where the law of life is that the strong eat the weak. There are no exceptions to the iron law of the empire, where the strong are respected and the weak are oppressed. This is true even for the emperor, who is at the top of the empire. Prisca Benedict, a member of the Vollachian Imperial Family, is still a young but intelligent girl when the Imperial Selection Ceremony, which decides the next emperor, falls upon her. The blood struggle, in which brothers and sisters kill each other and the last one to be chosen becomes the next emperor, begins under the cruel and beautiful flame of the treasured sword.
"It doesn't matter what happens. --This world is made to suit me."
An act in the history of the empire in which the reason of the strong overruns everything. --Burn, Scarlet Princess, burn. Burn away the obstacles to your destiny.
