The world was never the same after the Great Upheaval. The war between the gods had left scars that would never heal, a constant reminder of the devastation that had been wrought. The once blue skies were now a perpetual gray, like the ashes of a fire that refused to die. The earth trembled, its very fabric torn asunder by the conflicting powers that had clashed upon its surface.
And yet, from the ruins, something new emerged. A new world, forged in the crucible of chaos, where the laws of nature were twisted and distorted. The residents of this ravaged planet, once mere mortals, now found themselves imbued with powers beyond their wildest dreams.
At the age of eighteen, every individual would awaken to their newfound abilities, their potential quantified by a mysterious energy known as the "Power Scaling." This enigmatic force would determine their rank in the new world order, a hierarchy of strength and power that would shape the course of human history.
The tiers were strict, the rankings unforgiving. SSS, the pinnacle of power, reserved for the chosen few who would reshape the world in their image. Below them, the S and A ranks, comprising the elite warriors and mages who would fight to protect humanity from the shadows. The B and C ranks, the middle class, striving to make a name for themselves in a world where strength was the ultimate currency. And at the bottom, the D, E, and F ranks, the forgotten and the weak, struggling to survive in a world that seemed determined to destroy them.
But the true horror was not the ranking system, nor the powers that came with it. It was the gates, twisted portals that led to other dimensions, spewing forth monstrosities that defied imagination. The creatures that emerged from these gates were ranked according to the same tier system, their power and ferocity a constant threat to human existence.
As the world teetered on the brink of chaos, one thing was certain: only the strongest would survive. The era of heroes had dawned, and with it, the battle for supremacy had begun.
