Second Prince Allen of the Elysion Kingdom was not only strikingly beautiful, but also the object of overwhelming affection.
His older step-sister, First Queen Elizabeth, dotes on him and is ten years older. Princess Sylphi, a fiancée candidate from a neighboring country, is five years younger and wants him all to herself. When the intense feelings of these two powerful mages clashed, Allen’s life changed forever.
The two curses they cast combined and transformed Allen’s body. When the light faded, a small spirit beast with golden fur stood in his place.
"How adorable...! Now I can keep you as a pet on my lap for the rest of my life." "Found you, Onii-sama! I'll lock you up in a miniature garden so you can never go anywhere ever again!"
Barely escaping their madness with his life, Allen fled into the demon territory forbidden to humans: the Twilight Frontier. There, he encountered "monster girls"—lamias and harpies who had been chased from their flocks and were suffering from starvation.
The Chains of the Curse wrapped around Allen's neck acted as the ultimate buff, explosively increasing the girls' abilities and serving as an invincible weapon to mow down enemies. However, the more he used that power, the more "remote mana injections" (seconds) arrived from the heroines back at the royal castle, deepening his curse as a mascot and buffing him to be even more "fluffy."
Furthermore, even the monster girls he saved ended up completely falling for Allen's adorableness and the glimpses of the prince he occasionally showed. "Allen-sama, we will never let you go again. Please become our 'King.'"
Allen finds himself surrounded by even more "heavy love" in the very place he thought he had escaped to. Plowing his territory with his cursed chains and leading monster girls in his fluffy body—an unprecedented territory management fantasy begins!
—Will the prince truly be able to sever this chain of love and regain his human form!?
