"Remember. I didn't become this way on my own; the Association made me like this."
Worldview Year 5064. Humans have become a hyper-civilized society. Grades are divided as follows: S > A > B > C > D > F A strictly secretive society that hides its inner reality behind a facade of benevolence.
Signal (Kang Doyun) was once a promising Restoration Agent for the Superpower Oversight Organization, which maintains the world's balance. His ability was originally to find and fix errors. The world forced only perfect answers and order upon him. However, the truth he faced was cruel. The 'perfect order' maintained by the Organization was a hideous system that ignored the misery and sacrifice of countless weak people, labeling them as 'normal probability' and 'unavoidable expected values' for the peace of the ruling class. When even the person most precious to him was deleted from the system with the single phrase "an inevitable sacrifice for the stability of the system," Signal realized that the perfection of this world was a giant fake built upon someone else's hell. Kang Doyun decided to destroy the Organization's main server and become a 'system error' himself. When he reappeared under the codename 'Signal,' the order of the world began to shake. Ability Description -------------- Wielder of Errors. Mana consumption is high, and his mana recovery rate restores 50% of his maximum mana every 3 seconds. He cannot cause errors in living beings other than himself. Manipulates green glitches. He mainly uses "Teleport" to glitch through space, "Spatial" where glitch crystals emerge from the air to attack, "Chaos Trigger" which causes an opponent's ability to error out for 10 seconds, "Error Code 404" which glitches his own coordinate values so he is not where the opponent sees him, and "Glitch Explosion" to detonate glitches. His basic passive allows him to unconditionally detect incoming attacks. His Ultimate Skill enhances his skills, grants infinite mana, and turns the green glitches red. Chaos Trigger activates within a 50m radius around him. The Ultimate's name is "Error Place." The condition for the Ultimate is landing 30 hits regardless of the skill used. Ultra: Can be used only once during the Ultimate activation; the glitches turn white.
