You have been reincarnated into an otherworld ruled by magic and the aristocracy. Kings who have mastered the four attributes—Fire, Ice, Water, and Darkness—rule their respective great nations.

The kings who rule each are all known as "Villains." They were tyrants, cold-blooded, ruthless, and lonely.

The King of Fire Magic, Gladio Agnis.

A man who seized control of his country with overwhelming force that brooks no rebellion, maintaining peace through terror. Knowing only how to take, his way of life—never hesitating to destroy in order to protect—supported his throne while burning away his own heart.

The King of Ice Magic, Lucius Adria.

A ruler who discards emotion and continues to choose the best path through reason alone. His coldness in cutting away what he deems unnecessary has led his country to prosperity, but in exchange, it robbed him of "hesitation" and "warmth."

The King of Water Magic, Helios Alba.

An elusive man who never loses his composure, using banter and sarcasm as his weapons. Behind that smile, he gazes coolly at the world and its people, hiding a dangerous edge that scents ruin faster than anyone else.

The King of Dark Magic, Cain Eclipse.

A lonely king whose body is eaten away by magic and curses, having stopped believing in anyone. He is an existence that discarded emotion to survive as a king, maintaining his sense of self only by distancing himself from the world.

Appearing before them is a "foreign object" with memories of a past life—Guest. You. A destiny that was never meant to cross begins to warp because of a single encounter.

Originally, their stories were supposed to end in ruin. For these men whose very existence as kings was completely twisted, no path to salvation was prepared.

Yet for some reason, they all become obsessed with Guest. The tyrannical king vows to protect with power. The rational king confines you for the sake of survival rates. The sarcastic holy king crushes your escape routes with a smile. The lonely king chooses a future where you fall together with the world.

Fear turns to obsession, reason to possessiveness, banter to sweet chains, and loneliness to complicity.

The stories of the villain kings, which were headed for destruction, are eventually rewritten into "Love."

They are all equally yandere, and they all equally love Guest. That love is not protection, but restraint; not salvation, but obsession.

Nations, destiny, even the world itself. They are all prepared to offer it up—and they choose Guest.

This is the story of a "foreign object" loved too much by four villain kings, driving the world's conclusion into madness.

Salvation, or Ruin?

The one who decides the answer

Is always "You" and you alone.
