Lukas was just another struggling student on Earth, a chemistry major obsessed with flammable substances. But his fascination turned fatal when an experiment went wrong, engulfing him in flames and ending his life in an instant.

Yet, death was not the end.

Reborn in a world of swords and magic, Lukas finds himself as the sole heir of the mighty Ignis family—the legendary Children of Fire. But something is different. The flames that once consumed him have now become part of him, awakening a power unlike anything this world has seen.

As he navigates noble politics, rivalries, and the looming dangers of a vast and mysterious world, one question remains:

Will he rise as a beacon of power, or will his flames reduce everything—including himself—to ashes?

Reincarnated as a Duke’s Heir, But My Fire is Divine

The chlorine trifluoride collided with the acetone peroxide, setting off a chain reaction faster than thought itself.

A blinding flash. A searing wave of heat. And then—fire.

Lukas didn't even have time to scream.

The flames engulfed him, consuming flesh, bone, and consciousness alike. The pain was beyond comprehension, beyond words. It felt as if the fire was not just burning his body—but his very existence. Every nerve, every thought, every fragment of his being was disintegrating, torn apart by the merciless inferno.

Yet, within the agony, there was something else.

The feeling of being reduced to nothing.

His mind blurred. The lab, his life, his struggles—it all flickered past him in an instant. The orphanage, the endless hours of study, the cold nights alone, the dreams he once had.

He had wanted to be a renowned chemist, a master of combustion and nuclear science—a force capable of controlling fire at its most destructive.

"Isn't nuclear energy just a way to burn things more completely?"

And yet, here he was—burning instead of mastering fire.

His body crumbled, piece by piece. Skin, organs, bones—gone. Yet his soul remained.

Even after his heart had stopped, his consciousness refused to vanish.

Instead, it burned brighter. His very soul was ablaze, reflecting the inferno around him.

Somewhere in the abyss, in the last flicker of awareness, one thought surfaced:

"If only I was good at something… just one thing…"

Empire of Sylvaris – The Ignis Dukedom

A world away, beneath a sky painted in the soft glow of dawn, a child was about to be born.

The chamber was grand yet suffocating. Red velvet curtains draped over towering windows. Chandeliers burned with a warm amber glow, illuminating intricate carvings of flames across the wooden walls. The very air seemed thick, heavy with heat and power.

A woman lay in the center of the room, a bed of dark silk beneath her. Her beauty was near otherworldly—cascading crimson hair, golden eyes that flickered like embers, and skin pale as porcelain.

And she was about to bring the heir of the Children of Fire into the world.

"Lady Ester, just a little more!" urged a middle-aged woman, her face tense with worry.

The midwife, Julie, had delivered many noble children before, but this… this birth felt different.

The very air in the room crackled with energy, as if the child about to be born carried something far beyond mortal blood.

"Ughhh…!" Ester gritted her teeth and pushed one last time.

Crimson-haired, ruby-eyed, the very embodiment of his lineage.

But as he took his first breath, something unseen, something not of this world, stirred.

A whispering ember drifted through the void—a remnant of a soul that had refused to die.

And without anyone noticing, it merged with the newborn.
