A prophecy once foretold the downfall of humanity. Ten years later, that prophecy has come to pass. Earth is now a twisted survival game, and humanity is its NPCs. They are hunted for sport by cruel alien "Players" from the Dark Star. For humans, death is final. But as despair reigns, an ordinary office worker, Yun Qi, awakens as a legendary hidden class. He is the glitch in their system—the one NPC who can kill the Players. The war for Earth's survival has officially begun.
