Entering the Rule Horror with a Bug

Zero, who is incapable of feeling emotions, is forced into a bizarre horror game.

Every instance is a deadly trap, and every rule is a path to death.

A lone wolf, he is granted a cheat-level ability usable for only one instance. With absolute rationality, he breaks the rules and clears each stage without a hint of emotion.

The night-shift nurse, the enormous crawling shadow… While everyone else trembles in fear, he is busy calculating the optimal solution.

This is a survival contest of madness and silence, and all he wants is to make it to the end.
