In a world where demons and elves coexist, Adam Harris awakens in a strange place, completely without control of his body. His hands are shackled, and sharp spears are pointed at him, ready to pierce him. In a state of shock and panic, he breaks free from his shackles and cries out the question, "What the devil is going on here?"

A mysterious and stunning girl, enveloped in a mystical aura, responds to his words. Her eyes glow with bright flame as she turns to Adam, demanding he surrenders. "Surrender, demon!" At that moment, Adam feels a strange warmth inside him and, glancing behind him, discovers soaring black wings. He realizes that he has now become a demon himself and is a prisoner of the elven tribe.


However, on the brink of death, when he is about to be executed, a mysterious voice rings out in his head: "'Conquering Queens' system has been successfully activated!" This system offers Adam a chance at survival and the chance to become the lord of a harem where the beautiful elven queens will submit to him.

Adam's adventures begin as he plunges into an epic battle for power, love, and freedom. In this world steeped in passion and sexual intrigue, he faces dangerous adversaries and wins the hearts of beauty queens. But at every turn, he is haunted by inner demons and past secrets that could destroy everything he has grown to love and strive to achieve.
