The Savior Zero: Saving the World with a Unique Skill from Zero Magic

In a world where magic defines one’s worth, Ikuta Kouki was born with the rarest and most ridiculed condition of all—Zero Magic Power. While children effortlessly learned spells and society glorified sorcerers, Kouki remained powerless, mocked as a failure and treated as an outcast.

Meanwhile, the world was shaken by a Great Sorcerer’s prophecy:
The End of the World is coming, and only seven Saviors will stand between humanity and total annihilation.

These chosen Saviors quickly rose to fame. They were worshipped as divine protectors, celebrated as humanity’s hope, and granted immense authority. But fame can hide weakness… and blind people to the truth.

Five years later, when the End of the World finally arrived—
The revered Saviors proved to be frauds, utterly incapable of stopping the catastrophe.

As humanity crumbled, Kouki’s elder sister clung to her dying breath. Yet even in despair, she saw something no one else had ever noticed—a latent power hidden deep within Kouki, dormant and unfathomably strong. With her last strength, she cast the forbidden spell “Regression,” turning back time itself.

Her final words to him were simple, yet carried the weight of the world:
“I want you to save the world.”

Kouki awakens in the past—five years before the destruction—returning to a time when the world still believed in the false Saviors and dismissed him as a nobody with zero magic.

But now, things are different.

Through Regression, Kouki awakens to a mysterious new talent: Creation—a unique ability that lets him forge power from nothing. What he lacked in magic, he now replaces with limitless potential. No longer bound by society’s beliefs, Kouki begins crafting weapons, skills, and tools beyond the imagination of even the greatest sorcerers.

With the truth of the coming doom in his hands and the memory of his sister’s sacrifice burned into his soul, Kouki rises—not as a false hero, but as the true Savior humanity desperately needs.

To expose the frauds.
To protect the innocent.
To rewrite the world’s fate.

The boy once called “Zero” will become the one who saves everything.
