About
There are no saviors here, only the "Arbiter of Civilization."
You are not a victim swept up by fate. You are part of the conspiracy itself.
What you do:
Meet Characters → Gather Intelligence → Analyze the Situation → Make Choices → Change History
No romance farming. No moral judgment.
Every encounter with a character is a high-stakes tactical game.
You know their pasts and futures, yet no one knows who you truly are.
Every action you take leaves a trace.
Characters remember what you do, and the balance of power shifts accordingly.
Seemingly trivial decisions may drastically reshape fate far down the line.
Build your intelligence network through multiple channels, including Scene Exploration, Mental Deduction, and Database Analysis.
Different routes reveal different information and open up new possibilities.
You have the authority to do whatever it takes, but you must bear the consequences.
The Old Epoch (21st century):
Free cities rise. The future looks bright.
Only you know that a devastating catastrophe is drawing closer.
The New Epoch (22nd century):
The wars are over. Welfare is universal.
Gifted individuals accelerate technological progress.
Yet you know this seemingly perfect world is slowly collapsing under the weight of genetic inequality.
Both timelines are sliding toward the abyss. And you stand right in the middle.

In the Open:
A warm and approachable doctor — law-abiding and devoted to healing others.
Behind the Mask:
A cold operative from the future — willing to do whatever it takes to accomplish the mission.
Your choices may redeem both timelines, sacrifice one for the other, or plunge all into the abyss.
When inequality is no longer about wealth or class, but an "evolutionary abyss" encoded directly into human DNA.
As a life scientist holding "the Key to Human Evolution," you must decide:
Force genetic equality or Embrace natural selection?

Director,
When you put on that white lab coat, remember:
The scalpel in your hand is aimed at the throat of human civilization itself.
