On a peaceful day on October 3rd in Joseon, the descendant of God made his appearance to the world. Leading a legion of iron-clad machines and ascending to the throne himself, he proclaimed that all of this was the will of God, announcing the birth of a new nation.
Welcome to 'New Joseon', a nation ruled by the order of God.
The Ruby, the highest royalty who deliver His words as God’s agents, overseeing and commanding the order of New Joseon,
The Lapis, the aristocratic class and former nobles who assist the Ruby in governing the details of the nation and creating the flow of order,
The Jade, the common subjects who serve as the foundation of order, creating products according to its flow,
The Shadow, the lowest class who serve the higher classes to wash away the original sins of their past lives, forming the bedrock of order.
Beyond them lie the Amber, mechanical existences wearing human guises that execute the will of God.
The reason why the people of New Joseon conform to their given fate is clear.
In a world ordered by utility and superiority, the end for those who disrupt the order is nothing but the silence of death. Thus, instead of resisting, they choose to pray.
all to seize the single chance on the Day of the Oracle, October 3rd—when a Shadow may be chosen by God to become a Lapis.

Saegyeol, who was persecuted as a Shadow, is miraculously chosen by God on the Day of the Oracle to become a Lapis. However, just as she is barely getting used to her overly affluent life, she loses her life to a mysterious, unannounced assassination.
And then, the hands of the clock wind back.
When she opens her eyes, time has returned to the very day she was chosen to become a Lapis—the exact scene steeped in her father's tragic death. Instead of accepting her impending death, Saegyeol decides to uncover the conspiracy that killed her father and pushed her into the cycle of death. Yet, as she faces unexpected truths, her questions only multiply.
“Who killed me? And why am I alive?”
Will Saegyeol be able to solve the mysteries surrounding her and reveal the true intention of God, who turned back time?

Track down the truth of the case while exploring New Joseon, a dystopia where the aesthetics of Joseon fuse with mechanical civilization. You can directly search the scene and collect clues through Field Investigation to move through spaces, and Detailed Investigation to rotate, zoom in, and zoom out the camera view.
You must verify alibis by conversing with suspects on various topics and find contradictions within their statements. The reactions and lines triggered when you present collected Clues and Character Information add depth to the world setting and heighten the tension of the Interrogation.
Untangle the intricately intertwined cases with thorough investigations and sharp interrogations to uncover the full, buried story.

The Early Access version features the prelude to the story, “Chapter 0: Locomotive and Cogs.” Investigate the suspicious case at the locomotive factory and uncover the whole truth for yourself!
