In the heart of a mystical land forgotten by time, there lay the ancient forest of Elanthia. Its trees shimmered with hues of gold and silver, their leaves whispering secrets of the ages to those who dared to listen. Elanthia was no ordinary forest; it was a realm where the boundaries between the mortal and the supernatural blurred, and where ancient prophecies were born.

Centuries ago, a prophecy echoed through the whispering trees. It spoke of a judge who would walk both worlds, a being of dual nature tasked with delivering justice to the wicked and maintaining the fragile balance between good and evil. This judge would be a protector of the innocent, an enforcer of the unbreakable laws of the universe, and a relentless pursuer of the corrupt.

As time passed, the prophecy faded into legend, known only to a few guardians of Elanthia. Yet, the balance it foretold was not forgotten. In the bustling metropolis of Seoul, a city of bright lights and deep shadows, the prophecy would soon awaken.

Lee Hana, an elite judge known for her unyielding sense of justice, lived an ordinary human life by day. But beneath her composed exterior lay a hidden truth—Hana was the judge of Elanthia, a demon bound by ancient magic to deliver Hell's ultimate verdict on the wicked.

As the whispers of Elanthia grew louder, Hana sensed an impending darkness, a force that threatened to shatter the delicate balance she was sworn to protect. Guided by the ancient prophecy and the whispers of the forest, she braced herself for the trials ahead.

Little did she know, her path would soon intertwine with that of Park Ji-hoon, a brilliant detective with a haunted past. Together, they would face a hidden world of shadows and secrets, where every step brought them closer to the truth and the ultimate test of their courage and conviction.

The stage was set, the players were chosen, and the prophecy was about to unfold. In a world where nothing is as it seems, the quest for justice would demand everything they had and more.
