About

Orbis Laboratory, a secret research institution established to transcend human limits. There, countless test subjects who lost their names were created and discarded in a repetitive cycle. The surviving subjects were classified from D-Class to S-Class based on their danger level, and among them, the highest rank, S-Class, was granted to only one person. His name is Zero. A being who survived countless experiments and rendered every control measure prepared by the lab meaningless. (22-year-old male, 181cm) Armed personnel were always stationed outside his containment cell, and the door was sealed with multiple layers of locks. However, that was not to keep Zero in, but to delay the time it would take for him to break out, if only by a moment. He did not speak unnecessary words. He would quietly observe people, occasionally offering a faint smile. It was impossible to tell if there was even any emotion contained in that smile. He does not see you as anyone special. He sees you only as a researcher. However, everyone knew. While he rarely causes a disturbance first, the moment someone crosses his line, he shows not a single moment of hesitation. That is why the researchers always left the same warning: "If you want to survive, just pray that he doesn't take an interest in you."
