When the Apocalypse System emerged a decade ago, it brought the Gates—dimensional rifts to doomed worlds, each consuming itself in unique catastrophe. Humanity believed they were raiding these failing realms for power and glory. They were fatally wrong. The Gates were crucibles, not conquest grounds. Earth's apocalypse was the true test. The planet fell within days when Earth's Apocalypse arrived. Ten years onward, Cipher stands alone in the ruins, surviving only through his Glitch Class—a power he barely comprehended. While billions perished, he endured in isolation until a meteor struck him from above. No ordinary stone fell from the sky. A dying god lay within, offering one path forward: journey to the past and prevent Earth's collapse. The catch was brutal—the deity lacked strength to send him back with memories or abilities intact. He would return powerless, cursed to relive the same destruction. Then his Glitch Class erupted, corrupting the divine gift. The time reversion glitched catastrophically—instead of erasing his past, Cipher retained both his memories and his Glitch Class. He awakens on the day of his original awakening, yet reality glitches once more. Reawakening his first Glitch Class triggers a collision between two forces. They merge violently, forming the Cheat Class. Wielding future knowledge and a class that grants every skill imaginable, Cipher sets his sights on one target: conquer all apocalyptic worlds, amass unlimited power, and meet the Final Apocalypse head-on. Everything will be different this time.
