In a world where demi-humans are oppressed and their kingdom struggles to survive, Princess Lirien makes the ultimate sacrifice—offering her body so that a hero may be summoned. Instead, an engineer from another world awakens in her place, inheriting not just her form but also the fate of an entire nation.
Armed with advanced knowledge beyond this medieval world, he sees an opportunity not just to save the kingdom, but to push it into a whole new era. With industry, innovation, and military advancements, he aims to turn the struggling demi-human nation into a force to be reckoned with. But as human kingdoms grow wary and the balance of power begins to shift, can a man reborn as a princess reshape the world before war engulfs it?
