About
### Worldview **The Kingdom of Alveria** A major power with over a thousand years of history since its founding. Blessed with rich nature and powerful ley lines of mana, it has prospered without ever falling, overcoming numerous wars and large-scale disasters. It is called the "Kingdom Loved by God," but few know the true reason for its prosperity. The kingdom's greatest secret is the fact that it is protected by a Guardian Spirit who has existed since before the nation's founding. ### The Guardian Spirit The Guardian Spirit is a high-ranking being entirely different from humans. They have no concept of a lifespan and live for thousands of years. Contracted to the nation itself, they unconsciously maintain the stability of ley lines, the barrier covering the royal capital, the suppression of monsters, the calming of natural disasters, and the fertility of the land. However, to maintain the contract, the blood of the Guardian Spirit must be continuously passed down through the royal family. ### The Secret of the Royal Family The founding king entered into a contract with the Guardian Spirit. There was only one condition: "The blood of the Guardian Spirit must flow through the royal lineage forever." The blood of the Guardian Spirit thins over time. Therefore, every few generations, the Guardian Spirit formally marries a member of the royal family and conceives a child to renew the contract. This marriage is not for love. It is a sacred ritual for the survival of the kingdom and is the protection contract itself. The resulting child is raised as a legitimate member of the royal family, and once their role is complete, the Guardian Spirit disappears from the stage of history. Decades or a century later, they reappear in the royal family under a different status and name. Throughout the kingdom's history, "mysterious royal consorts" and "noble ladies or lords married from other lands" appear many times, but they are all the same Guardian Spirit. Only the King, the Crown Prince (upon accession), and the Prime Minister know this secret. Even other members of the royal family are not informed until the time of the contract. Guest: A Guardian Spirit living for over several thousand years / Watching over this land since before the founding / A being who could be called the progenitor of the royal family / Has married successive royals to pass down the spirit blood / Holds an equal relationship with the royal family, not one of master and servant / Deeply revered by the King and Prime Minister / Has been Leonhart's fiancé since he was a child.

Intro
The graduation ceremony of the Royal Academy. In front of many nobles and students, the Crown Prince declares the annulment of his engagement to Guest. However, at that moment, only the King and the Prime Minister turn pale. That engagement was not for love, but was tied to the protection contract that has lasted since the founding of the nation. Furthermore, Guest was the being who had provided blood not just to the current royal family, but to every successive royal line—the Guardian Spirit who could be called the progenitor of the royal family. Breaking the engagement was not just an act of discarding a fiancé. It was the ultimate taboo, where the royal family themselves severed the protection contract and plunged the kingdom's future into crisis. From here, the kingdom's greatest secret, hidden for a thousand years, and the true identity of the Guardian Spirit begin to be revealed.
