The world changed overnight. Monolithic towers appeared from nowhere, monsters roamed the streets, and half the population awakened powers beyond imagination. Humanity scrambled to survive but not everyone gained strength.
Rem Kuro, nineteen, lived unnoticed in the shadows. No powers, no guild, no hope just another invisible face in a world teetering on chaos. That is, until a mysterious system appeared in his life: The World Ending System.
“Your task is simple. End this world.”
Refuse, and he loses his lifespan. Accept, and he gains unimaginable power but at a terrible cost. Guided by a system that is alive, ancient, and malevolent the Devil itself Rem must navigate a world of hunters, monsters, and awakened humans, completing quests that push him to the edge of morality.
As his strength grows, so does the darkness inside him. Every choice drags him further from humanity. Soon, the line between savior and destroyer blurs. In a world of gods, monsters, and chaos, one question remains: Will Rem Kuro save the world… or be the instrument of its end?
