Space twisted.
Not violently. Not chaotically.
It folded around Aethon like a curtain being drawn aside.
The void vanished, replaced by heat—thick, suffocating heat that pressed against his skin the moment his feet touched solid ground.
SSSS—
The air hissed.
Aethon straightened, boots sinking slightly into cracked black stone veined with glowing crimson lines. The ground pulsed faintly, like a living thing breathing beneath his feet.
Demon territory.
The sky above was a permanent storm of red and black clouds, swirling endlessly, lightning crawling through them like veins of fire. There was no sun. No moon. Only a distant glow, as if the world itself was burning from the inside.
Aethon didn't move for several seconds.
He stood still, senses expanding outward.
The smell came first.
Blood.
Old blood. New blood. Burnt flesh. Sulfur. Fear.
Then the sound.
Far away, something roared.
Not a beast.
A command.
Aethon's eyes narrowed slightly.
"So," he murmured, "you already know I'm here."
The pressure in the air thickened, heavy enough that a weaker being would have fallen to their knees. Demonic energy rolled across the land in waves, each one stronger than the last.
BOOM—
The ground trembled.
Aethon took a single step forward.
Then another.
With each step, the pressure bent around him instead of crushing him, his celestial aura pushing back calmly, dominantly. His presence alone carved a path through the oppressive energy, the crimson lines in the ground flickering erratically as if confused.
He stopped at the edge of a massive chasm.
Below it stretched a city.
Not built—grown.
Jagged towers of black bone and obsidian rose upward, connected by bridges made of fused skulls and hardened flesh. Rivers of molten energy flowed through trenches carved into the streets, illuminating countless demonic figures moving below.
An army.
Thousands.
No—more.
Aethon stood at the edge, cloak fluttering slowly behind him.
"They gather quickly," he said quietly. "Or perhaps they were already waiting."
CLAP.
The sound echoed across the chasm, sharp and deliberate.
Aethon turned his head slightly.
From the air itself, something descended.
No wings.
No spell circle.
Just raw power forcing reality aside.
WHOOOM—
The pressure spiked.
A massive figure landed on the opposite side of the chasm, stone shattering beneath its feet. The impact sent cracks racing outward, chunks of obsidian tumbling into the abyss below.
The demon straightened.
It stood nearly three times Aethon's height, its body armored in natural black plating etched with glowing crimson symbols. Two massive horns curved backward from its skull, cracked and battle-worn. Its eyes burned gold, ancient and intelligent.
A blade rested on its shoulder—far too large to be wielded by anything less than a monster.
The Third Demon General.
Its grin split its face wide, revealing rows of jagged teeth.
"So the rumors were true," it said, voice deep and layered, vibrating through the land itself. "They really sent you."
Aethon met its gaze without flinching.
"They always do."
The demon laughed.
HAHAHAHA—
The sound rolled like thunder, demons in the city below pausing, turning their heads upward as the laughter echoed.
"I expected more," the general continued. "A Demon Slayer should look… bigger."
Aethon exhaled slowly.
"Size has never been my weakness."
The demon's eyes gleamed.
"Good," it said. "Because I would hate to be disappointed."
The air between them distorted.
Observers stirred.
Far above, beyond the layer of demon skies, hidden from mortal sight, the celestials watched. Crystal projections hovered in the void, showing the battlefield from multiple angles.
Some leaned forward.
Others clenched their fists.
"That's the Third General…"
"Even two celestials couldn't bring it down."
"He's walking straight into death…"
Among them, a young celestial whispered:
"Aethon won't lose."
Higher still, the Ancient Ones observed.
Silent.
Calculating.
Five of them watched especially closely.
On the battlefield, Aethon reached up and loosened his cloak, letting it fall away behind him. It disintegrated before it touched the ground, consumed by the ambient demonic energy.
He rolled his neck once.
Then twice.
"State your name," he said calmly.
The demon raised a brow.
"You wish to remember it?"
"I wish to acknowledge you," Aethon replied. "Before I end you."
The demon's grin widened.
"Bold."
It slammed its blade into the ground.
BOOM—
"I am Zar'keth, Third General of the Demon King," it roared. "And I have killed gods older than your kind."
Aethon nodded once.
"Aethon."
That was all he said.
The demon's pupils contracted.
"…Just Aethon?" it mocked. "No title?"
Aethon's hand rested on the hilt of his sword.
"You don't need to know the rest."
The world exploded.
BOOOOM—!
Zar'keth vanished from where it stood, the air detonating as it crossed the distance in an instant. The massive blade came down in a brutal vertical arc, tearing space apart as it descended.
Aethon moved.
SHING—!
Steel met steel.
The impact sent a shockwave ripping outward, the chasm walls collapsing inward as chunks of rock vaporized. The clash rang across the city below, demons screaming as structures shattered.
The two stood locked, blades grinding against one another.
Zar'keth's eyes widened—just slightly.
"…You stopped it."
Aethon leaned in.
"You're slower than I expected."
He twisted his wrist.
CRACK—!
The demon general was hurled backward, skidding across the ground, plowing a trench dozens of meters long before stopping.
The city below erupted into chaos.
Aethon didn't pursue immediately.
He stepped forward slowly.
Zar'keth rose, laughing.
"Good!" it roared. "Good! Let's see how long you last!"
It slammed its fist into its chest.
BOOM—!
Crimson energy erupted outward, armor cracking as something inside awakened. The symbols across its body flared violently, demonic power skyrocketing.
The pressure doubled.
Then tripled.
Even the celestials watching felt their breath catch.
Aethon's eyes sharpened.
"So this is your true power," he said. "No wonder they struggled."
Zar'keth charged again.
This time, Aethon met it head-on.
The battlefield became a blur of motion.
SHING—!
BOOM—!
CRACK—!
Blades clashed again and again, sparks raining like meteors. Aethon's sword moved with terrifying precision, deflecting strikes that could cleave mountains, each movement economical, flawless.
But Zar'keth adapted.
Its attacks grew faster.
Heavier.
More brutal.
Aethon slid back several steps, boots carving lines into the stone.
Observers tensed.
The demon general grinned, blood running from a shallow cut across its cheek.
"You bleed," it said.
"So do you," Aethon replied.
He inhaled.
Then—
He drew more power.
Celestial energy surged through his body, radiant lines flashing briefly across his skin before vanishing. The air vibrated as his presence deepened, the pressure shifting from demonic dominance to something far more terrifying.
Balanced.
Controlled.
Deadly.
Zar'keth's grin faltered.
"…Ah," it said slowly. "Now I see why they fear you."
Aethon raised his sword.
The blade hummed, ancient runes igniting along its length.
HMMMM—
Far above, an Ancient One spoke for the first time.
"That sword…"
Another replied, voice tense.
"We gave it to him when he was still a child."
On the battlefield, Aethon took a step forward.
Then another.
Zar'keth roared and charged.
The two collided in a blinding flash of light and darkness—
And the world screamed.
