In the year of 2017, South Korea has successfully kept its monarchy system within the castle walls. Kings and Queens do still exist in the world, although they do hold much less power. With a modern government now working hand-in-hand with the King and Queen, the Royal Family is left with the two main responsibilities of representing the country and protecting it. Lee Yuri, being last of the Sacred Bone Family, is the only one left for the throne. Her Father had passed away years before, and her Mother has mysteriously fallen ill. Well aware of the weight of her future responsibilities, she has spent much of her life learning of her country and learning how to protect it. Now 16, she is everything a leader must be: intelligent, decisive, and most importantly, a skilled warrior, being able to smoothly operate both modern and ancient weapons. Moon Junhui is a True Bone, or that's the identity he assumes. Known as an intelligent and also a highly praised warrior and scholar, everyone looks upon him favorably. Only, he's actually the leader of a notorious rebel group from the outskirts of Seoul. His father killed off by government officials years ago, his group does whatever they can to rid of the current President who ordered his father's killing. After Yuri's mother turns much too weak to rule, she is coronated to the throne on her 16th birthday. That very day, she is ambushed the ever-praised Junhui. Only, he's come to strike a deal. He gets revenge on the one responsible for his father's life, and she secures her throne from the enemy forces within the country, and avenges the one for her mother's. One catch.
