Dormoto Uraska was once a fragile demi-human, born into a world where cruelty was law and strength meant survival. Orphaned after human hunters slaughtered his parents for trade, he was dragged into slavery and lived a life of endless torment. As time passed, pain hardened his soul, and hatred gave him purpose. Deep within the darkness, he discovered a spark of power. That spark grew until he was no longer a boy, but a being feared across continents — the Demon Lord who razed cities, shattered armies, and nearly erased humanity from existence.

In the final years of that world’s collapse, Dormoto abandoned it all, stepping through a mysterious portal that led to a quiet, magicless realm. It was a modern human world—one without monsters, magic, or wars. There, he took a new name and tried to live a life of peace, attending school, hiding his powers, and distancing himself from everything he once was.

But fate was not so merciful.

One night, the same portal that once granted him escape reopened. Without warning, it swallowed him whole and dragged him back to the very world he destroyed. Time had passed, but the scars of his reign remained. He returned not to the burning lands he left behind, but to a world reborn from ash — ruled by demi-humans, beasts, and monsters. Humanity had fallen and now survived only in one shattered kingdom, clinging to its last fragments of pride.

Dormoto arrived alongside seven strangers—new heroes summoned from different worlds to rebuild the future of mankind. Confused and annoyed, he found himself at the center of fear and awe. The king who once begged for mercy at Dormoto’s feet now fell to his knees again, unable to hide the horror on his face. Even the land seemed to remember his touch.

The world had changed. Arc Angels had descended after Dormoto’s disappearance and reshaped civilization. They rebuilt the balance of the realm, gifting power to others and ensuring that no tyrant could ever rise again. To them, Dormoto was a threat reborn.

The other summoned heroes began their training, hopeful and unaware of who stood among them. Dormoto, however, had no interest in saving anyone. All he wanted was to return to the peaceful world he was torn from. But that return required one thing: the Heart of the Golden Dragon — the only key to the portal between worlds.

Forced to remain, chased by suspicion and surrounded by enemies and naive allies, Dormoto began his journey not as a hero of light, but as a tired soul searching for escape. Along the way, he would cross paths with the remains of his old empire, face the worship of creatures who still followed his ancient rule, and come to terms with the legacy of destruction he left behind.

In a world that now fears and worships his name, Dormoto walks again — not as the Demon Lord, not as a savior, but as a man caught between two worlds, hunted by the past and cursed by the role of a hero he never asked for.
