In the near-future city of “New Uranos,” people’s lives are managed by the AI system EDEN. It calculates optimal choices, corrects deviations within the city, and guides everyone toward what the system considers the “most correct” future.
And you are the chosen “Memory Restorer.”
Through Helios’ restoration device, you can enter the past, investigate events deemed abnormal, and attempt to correct mistakes that should never have happened. Accidents, disappearances, altered records, and inexplicable memory deviations all point to the same question:
Can the past truly be restored?
Enter the Past and Correct What Went Wrong
This is a sci-fi mystery visual novel centered on time regression, memory restoration, AI governance, and multi-ending choices.
You will follow Ciel through multiple restoration missions, investigate the truth behind each incident, read records, piece together clues, and make choices at critical moments. Every restoration affects reality. Every choice may create a new deviation in the worldline.
You may believe you are only correcting the past. But before long, you will discover that what has been rewritten may not be limited to events. People’s memories, and even the reality you believe in, may have already been altered.
Her, or the World?
Through repeated restorations, the protagonist gradually approaches the truth hidden by the system. And the girl who once shared an important promise with him returns to his fate once more.
If the optimal solution given by the system demands that you abandon her. If saving her means the world will deviate from its intended future.
Will you obey EDEN’s judgment, or rewrite the so-called optimal solution with your own hands?
