The Extra is a Genius!?-Chapter 163: Azure Flame [PS Bonus]

The moment the barrier broke, Marcus didn’t breathe.

It didn’t shatter like glass—it melted. Slowly. Unevenly. As if something inside had torn it apart from the core.

And when it fell, the smoke rolled out like a tide.

The first thing he saw through it was Noel, still standing—barely. His back turned, completely exposed. His head bowed. One hand on his knee. Revenant Fang planted in the ground like it was the only thing keeping him up.

And behind him...

The monster moved.

Twisting, groaning, alive.

"Get away from him!" Marcus roared.

The ground exploded under his boots as he surged forward, stone fists clenched, mana roaring through every vein like wildfire.

He flew past the Holy Guards before they could stop him, already mid-leap, already bringing his weight down like a comet.

"Sorry I was late too..." he muttered, more to himself than anyone else.

But he wasn’t saying it for Noel.

He said it for the children.

For Erick, Mira, the other ones he played with.

For every face that screamed in silence from inside that thing.

He hit the ground in front of Noel like a boulder crashing down a mountain.

The abomination shifted toward him, slow but deliberate—each step dragging mutated limbs that squelched and snapped with every motion. It was still regenerating, still alive despite everything they’d thrown at it.

Noel didn’t move behind him. He was breathing, but that was it. Barely holding on.

Charlotte was kneeling beside him now, trying to help, but Noel gripped her wrist. Refusing. Protecting her... even now.

Marcus turned his attention forward.

The creature’s form pulsed with grotesque rhythm. Clusters of half-formed faces stretched along its surface, silent now, but somehow worse for it.

’We have to end their suffering.’

He gritted his teeth, grounding his stance.

Around the chamber, the Holy Guards were already falling into formation, led by Garron and Laziel. They didn’t speak. They knew what was happening.

They could see it—

Marcus was going in alone.

And he didn’t care.

’It’s me or nothing.’

He lowered his center of gravity, sword glowing again with mana.

"Let’s end this."

Marcus moved first.

The stone beneath his feet cracked open as he dashed forward, mana pulsing outward with every stride. He swung his blade with full force into the creature’s leg—a pillar of fused limbs, exposed nerves, and clawed bone—sending a shockwave of earth magic through the abomination’s body.

The monster staggered.

But then, it reformed.

Right before his eyes, the damage healed instantly—flesh knitting over unnatural muscle, teeth rearranging into shape, skin bubbling back into place.

"Tch... not fast enough," Marcus hissed through clenched teeth.

He struck again. This time from above, slamming his sword down with all his weight.

Crack. Tear. Regrow.

It wouldn’t stop.

He jumped back, blade dripping with black ichor, his arms trembling with effort. Gritting his teeth, he looked down at the weapon in his hands—his faithful blade, chipped and scorched from the last few days of hell.

He closed his eyes.

Erick’s face. The other children. Noel, nearly broken behind him. Charlotte on her knees.

Then—

"Time to test what I trained for in Nivaria during the break..."

He exhaled—and let go.

The mana within him surged, but it didn’t burn. It concentrated.

His blade responded.

A flicker at first—then a steady blaze of blue fire ignited along the steel, coiling around it like a living spirit. The temperature didn’t rise... it dropped. Dense. Heavy. Devouring.

Not normal flame.

This was something else.

Something that didn’t just burn—

It erased.

Marcus opened his eyes, the reflection of the flame dancing in them.

"Let’s see you heal from this."

The creature screeched as Marcus dashed forward, blade blazing with azure fire.

He didn’t slow down.

Every step cracked the floor beneath him, pressure swelling behind his advance. The abomination raised one of its massive limbs—distorted, twitching, dripping with corruption.

Too slow.

Marcus leapt.

He raised his blade, flame roaring across the steel, and shouted:

"Devouring Flame!"

Then he drove the sword straight into the creature’s chest.

There was no explosion—just silence.

The flame didn’t flare.

It devoured.

The azure blaze spread like liquid across the abomination’s skin. Where it touched, there was no fire, no light—only erasure. Flesh turned to ash. Veins collapsed. Bone dissolved.

The malformed faces along its side screamed—a desperate, cracking chorus that faded one by one into nothing.

Marcus yanked his sword free and spun, slicing a wide arc across its torso.

The blue flame followed the cut, carving deep into its mass.

The monster reeled backward—actually retreating, chunks of itself sloughing off and evaporating mid-air. For the first time... it looked afraid.

Behind him, he heard Laziel call orders, the Holy Guards organizing into support formation. Spells flew, spears of light pierced the edges of the beast. Protective wards sealed behind Marcus.

But they weren’t pushing forward.

They knew who this fight belonged to now.

And Marcus didn’t look back.

"You don’t get to keep what you broke."

The abomination let out one final, trembling roar.

Its mass began to collapse inward as the Devouring Flame spread—no longer needing Marcus to guide it. The blue fire crawled across every twisted limb, every shrieking face, every malformed edge of what used to be children.

No more cries. No resistance.

Only silence.

And then—It crumbled.

The entire monstrosity folded into ash, its body disintegrating where it stood, sinking slowly into a mound of black dust. No explosion. No violent thrash. Just... release.

Ash drifted into the air, soft, lightless.

The battle was over.

Marcus dropped to one knee.

His sword dimmed.The flames died out.His heart pounded, his arms trembled—but he stayed conscious. Still standing.

He looked up.

Across the ruined chamber, Noel and Charlotte were being tended to by several Holy Guards. He could see the relief in their posture, the exhaustion in their faces. One guard supported Charlotte by the shoulders; another worked to stabilize Noel’s pulse.

They were alive.

All of them.

Marcus lowered his head, just for a moment.

’We did it.’
