- In the distant future, human civilization is on the verge of extinction due to a cosmic disaster ("The Big Crunch"). The last ark ship "Europa" carrying the core data of each civilization escaped from the earth, but encountered space-time turbulence when passing through a wormhole, causing the shipboard AI system to materialize the historical data of human civilization into a "civilization avatar" - a humanoid life form with national characteristics and memories.
- These incarnations are placed on an Earth-like planet called "Gaia-β". They must activate the "Civilization Fire Agreement" of the Ark by rebuilding civilization and competing for resources, and ultimately decide which civilization can gain control of the Ark and become the seed of the new universe.
Purpose: Looking for civilization
