Zero, who lacks emotions, is forced into a weird game.
Every copy is a dangerous situation, and the rules are death traps.
As a lone wolf, he was given a BUG-level ability that could only be used in a single copy. He broke the rules with absolute rationality and passed the level indifferently.
The night watch nurse, the creeping shadow of the giant phagocytosis... When others are trembling in fear, he is only calculating the optimal solution.
This is a race for survival between madness and silence, and he just wants to get to the end.
