On September 3rd, 2085, every adult on Earth awoke to a nightmare: they were in Hell. The rules were simple and brutal: grow stronger to earn a place in Heaven, or die and be forever consumed by Hell's eternal torment. No one warned them that Hell itself was a living entity, a realm of shifting horrors and relentless malevolence.

In this crucible of fire and despair, humanity's darkest and brightest aspects are laid bare. Alliances form and shatter, love blossoms amidst the ashes, and betrayal lurks in every shadow. Greed and desperation drive many to madness, while others discover inner reserves of strength and courage they never knew they possessed.

But the nightmare doesn't end with one generation. Every year, on September 3rd, newly turned 18-year-olds are cast into this inferno, perpetuating a cycle of suffering and struggle. As they battle demons, devils, and each other, their ultimate goal is not just to survive, but to grow stronger and reclaim their place in the world they once knew.

Witness humanity's fight for redemption in a story of love, betrayal, and unyielding will against the relentless forces of Hell.
