The system says Akashi Riku shouldn't exist. No stats. No class. No level. A total error. But when monsters invade Tokyo, the "bug" fights back. With stolen skills, hacked weapons, and dev-only menus he shouldn't have, Riku rewrites battles in real-time. The hunters can't track him. The guilds can't recruit him. And the system moderators? They want him deleted. Too bad for them. Zero Status doesn't mean powerless. It means limitless.
