Luce, who had been abused by her parents, thought she would find happiness by marrying Orth, the first prince of the Zeon Kingdom. However, Orth implants a "Demon Stone" in Luce's body, planning to use her as a tool to bear a child with strong magical powers. In her despair, Luce is confronted by Gilzark, the emperor of the Dragaless Empire. Gilzark, who claims to have come to destroy the Demon Stone, also attempts to take Luce's life. In this desperate situation, Luce tries to use magic for the first time, but the power of the Demon Stone causes the magic to change unexpectedly, and a spell of obedience is cast upon Gilzark. "If you say you're going to keep me as your pet, you're also willing to take care of my magic power replenishment, aren't you?" Apparently, the method of magic power replenishment involves kissing and even XXX?! Their power dynamics reverse during the magic power replenishment... Even while under the obedience spell, the cold-hearted emperor doesn't easily submit. Will Luce be able to subdue Gilzark and escape from Orth...?
