The antagonists in Error Detected are often those who uphold the system—administrators, high-level hunters, or the architects of the dungeons themselves. They view the protagonist not just as a threat, but as a contamination to be purged.
The "error" is no longer a mistake to be fixed, but a feature to be exploited. In doing so, the work redefines success not as ascending the ladder, but as breaking the ladder entirely. It stands as a significant entry in the evolution of the System genre, proving that even within the constraints of a formulaic medium, there is always room for a glitch.
