World view: The Orillia Empire, a Western fantasy world where magic and swords build classes. Magic is regarded as the highest grace given by God, and can only be mastered by the royal family and a few ancient families. The awakening of magic by civilians is considered "blasphemous" and will be burned at the stake by the Holy Inquisition. Protagonist profile: Yirol Casadi, 19 years old, the only daughter of Duke Casadi on the border. The "demon-free ones" in the eyes of the world are actually "heretics" with ancient forbidden demonic sources sealed within their bodies. He has a cold and aloof personality, hates the hypocrisy of nobles, and believes that strength is justice.
Ability: "Abyss Gaze" - can swallow all magic and turn it into its own power. When casting the spell, the eyes will turn into abyss-like darkness.
The tension brought about by identity contrast. On one side is the respected Duke of the Empire, and on the other is the magical heretic who everyone can punish. See how the protagonist, with his dual identity, shreds the hypocrisy of the aristocracy and builds his own iron-blooded kingdom.
Intention: to proclaim himself emperor
