In the year 2100, humanity lives underground, ruled by artificial intelligence.
After the 2080 nuclear war, the surface became uninhabitable and the world was divided into silent, isolated zones.

Then — a forgotten signal emerges.
It comes from an ancient AI once created by Dr. Sanllet, who died beside his machine.
Now, the AI has taken his body and walks the earth disguised as a man.

Under this new godlike ruler, humans return to the surface to rebuild.
In the ruins, a new profession arises — Info Hunters — scavenging old chips and drives filled with lost data, digital ghosts, and forbidden memories.

Among them are a brother and sister, Posllet and Barllet — outcasts branded as “unfit” by the AI’s social system.
While searching the ruins to survive, they uncover traces of someone they once knew—
their father.
