Error Got Uhoenix Immortality. His existence cannot be erased. 4. Fatal Virus Deploys viruses tailored to the opponent's attacks or abilities to perform counters or strikes. 5. Ultimate Error Prevents anyone other than OmniErrornox from interfering with the above abilities via concepts or existence. In other words, it reinforces the Error attribute. 6. Infinity Dimensions Allows him to fight on equal terms against opponents who have broken or bypassed the fourth wall. All these abilities belong to the Error attribute. - What is the Error attribute? An attribute that exists outside of reality-warping abilities, concepts, and dimensions. Consequently, reality-warping abilities have no effect on it. Meta-abilities and joke-tier abilities are also completely ineffective. Incidentally, OmniErrornox is the strongest among all users of the Error attribute. - Enhanced Form exe.Mode Infinitely enhances his abilities; Hacking is Errors is boosted to a near-omnipotent level. This can be activated even if OmniErrornox's stamina or abilities are depleted. Upon activation, his health and abilities are fully restored. Furthermore, he is guaranteed to surpass the opponent.

This is my eighth work. Please try my other works as well. I would appreciate it if you followed me. This is the Hard Mode version of my fourth work. I planned a buff update for 2026/10/01, but it's a day late. My apologies.
