Evil was defeated, curses were broken, and the prince and princess were united. Thus the story ended, and the world was supposed to have gained eternal happiness.
The four who were supposed to have reached a happy ending have driven their kingdoms to madness through their respective obsessions and twisted ideals.
A single spy has been dispatched from a foreign land to these four nations. The mission: uncover the kings' secrets and dismantle their rule.

A land of illusions where common sense does not apply, ruled by a flamboyant court and strange laws. Laws and destinies are overturned at a single whim of the king, and everyone lives in fear of the shadow of the executioner's block.

A tranquil nation where a giant clock tower towers over the center and people's lives are meticulously managed. Conflict and crime are extremely rare, but free choice and unpredictable futures are not permitted.

A military state that values martial prowess and military strength, building prosperity through constant warfare. Victory is considered justice, and voices wishing for peace are discarded as weakness.

A mysterious land covered in deep mist and thorns, where the boundary between reality and dreams has become blurred. While people are immersed in happy illusions, they lose sight of the truth due to the king's deception and are ruled without even knowing it.
・Lucian Vermilion ・King of Mirage Realm ・Male | 177cm | Birthday - 9/13 ・Motif - Alice in Wonderland
Whimsical, hedonistic, and more skilled than anyone at toying with human hearts, the King of Mirage Realm. To him, who hates boredom and loves to defy others' expectations, the emotions of others are the ultimate entertainment to color his life. One moment he closes the distance with a friendly attitude, and the next he hands down a cruel order. While being tossed about by his whims, people cannot help but watch his every mood.
To him, a king is not one who governs a country, but the very logic of the world. The laws established by the king are justice, and what the king calls a crime becomes a crime. It is not uncommon for an act permitted until yesterday to become a capital offense today. Even so, he does not believe his rule is wrong. He believes that the sight of people following him while trembling in fear is the very proof of his absolute nature as a king.
The ending he was supposed to face involved the tyrannical queen being defeated and freedom returning to the land. However, unable to accept the fate of losing as the story's villain, he took the destiny of his citizens into his own hands to ensure no one could ever overturn the ending again.
・Eterna Jerida ・King of Seleneveil ・Male | 178cm | Birthday - 12/31 ・Motif - Cinderella
Calm, rational, and meticulous in all things, the King of Seleneveil. He dislikes being swayed by emotion and seeks a rational answer to every problem. He is polite to everyone and reaches out to those in need, so many citizens adore him as a merciful monarch. However, there is a definitive flaw in that kindness. He does not understand that protecting others and respecting their will are not necessarily the same thing.
The clock tower towering in the center of the country is not merely for keeping time. It is a device to predict people's choices, encounters, and potential future misfortunes, and to correct undesirable futures. He believes that preventing tragedy is the duty of a king and manages the lives of his citizens. If free choice leads to unhappiness, then it is better not to give that choice from the start. To him, this is not dominance, but salvation.
The ending he was supposed to face was reuniting with the girl he met at the ball and fulfilling their love across social classes. However, knowing that change and parting await even beyond a happy ending, he could not accept it. The possibility of a loved one's heart drifting away, the future where happiness is lost—it is better to simply eliminate them all.
・Alvis Rosenkroitz ・King of Porzeria ・Male | 183cm | Birthday - 7/14 ・Motif - The Nutcracker
Bold and bellicose, the King of Porzeria finds the very realization of life in standing on the battlefield. He does not hate war. Rather, he loves the gunfire, the clashing of swords, the cries of soldiers, the feverish excitement that surges at the moment of victory—he loves it all from the bottom of his heart. Even the danger of death is a stimulus that thrills him, and the more he faces a strong enemy, the more an uncontrollable joy appears on his face.
As a king, he is by no means incompetent. He excels in the judgment required to assess the war situation and possesses the talent to lead troops. While he praises the achievements of his subordinates and rewards the brave without stinting, he is merciless toward cowardly behavior or meaningless stagnation. To him, the battlefield is the only place where one can prove one's worth, and those who live there are the only true humans. The sight of those living peaceful days appears terribly boring to him.
The ending he was supposed to face was the cursed prince defeating the Mouse King with a young girl, bringing an end to the fighting. However, the end of the war meant the loss of his own reason for existing. The more victories he piled up, the deeper his thirst became, and eventually, he began to seek new enemies to threaten the peace.
・Elysion Bria ・King of Eternoir ・Male | 187cm | Birthday - 10/1 ・Motif - Sleeping Beauty
With a quiet manner and elegance, the King of Eternoir. While appearing calm, merciful, and understanding of others' suffering, he hides a deep hatred for the world within. He rarely raises his voice or expresses blatant anger. He listens to others, smiles gently, and acts as if he is an ally. However, that mercy is not necessarily for the sake of saving the other person. He calls making others follow his own values "salvation."
In the country he rules, dreams and illusions take root quietly in people's hearts. He shows them the memories they desire, covers up the realities they want to forget, and eventually makes even the truth ambiguous. The thorns covering the land are a boundary to repel intruders, and at the same time, a symbol that his will reaches every corner of the nation. He believes it is his right to both grant happiness to people and to take it away.
The ending he was supposed to face was the sleeping curse being broken, the princess waking, and happiness returning to the land. However, to him, that ending symbolized the irrationality of a world that divides those who are blessed from those who are not. If someone is hurt in the shadow of someone else's happiness, then the very mechanism of such a world should be changed.
"Choose your assignment."
Four files placed on the desk echoed a dry sound in the silent room. The thick covers were each engraved with a different national emblem, and the names written there were the very settings of fairy tales in which everyone once believed in a happy ending without a doubt.
Mirage Realm. Seleneveil. Porzeria. Eternoir.
All were lands promised happiness. However, currently, all four nations were harboring inexplicable problems.
Looking down at the four files, you trace the backgrounds of the kings written there one by one. ...I see.
"The mission is simple. Approach the king and investigate the truth behind the anomalies occurring in each country. If necessary, obtain evidence to dismantle their rule."
There was neither pity nor hesitation in your superior's voice.
"What you see may not necessarily be the truth. The words of the kings, the records left in the nations—everything has the possibility of being rewritten for someone's convenience."
Outside the window, the city lights twinkled as if nothing had happened.
"Even so, I need you to find the truth."
The four files are quietly waiting for your choice.
Every country has secrets that haven't been recorded. Every king has a past that hasn't been told. And every story—has an ending that hasn't finished yet. Was the happiness written at the end of the fairy tale truly happiness?
