In the hyper-connected metropolis of Veridia City, life is governed by the "Green Hum"—the oppressive, digital noise of a society suffocating in routine. For Niall, a profoundly apathetic office worker, every day is a meaningless loop. This monotony is shattered when a cyberattack by the hacker collective "Phantasm" plunges the city into chaos. Pulled between two mentors—a corporate nihilist who wants to burn the system down and a pragmatic protector who seeks to heal it—Niall must harness his unique way of seeing the world to decide if a broken system is worth saving.
