What is a Demon King? Who is a Demon King?
For some, he is evil incarnate—a nightmare given form, the root of all calamity—the shadow behind every tragedy, the tyrant to be slain. To them, he is not a person but a symbol of fear, of hatred, of chaos. Something to destroy.
But to others… he is salvation. A sovereign who embodies strength in its purest, most brutal form. A living will, unshaken by doubt or compromise. The one who carved order out of the madness of the abyss.
If he commands you to live, you live. If he commands you to die, you die. His word is not questioned—it is law. Not because he demands it, but because he can.
He is the peak. The strongest among all demons. The absolute ruler of the Demonic Continent. A force so overwhelming that even the gods hesitate before his gaze.
His presence warps the battlefield. His name reshapes the histories of kingdoms. He is a throne carved from bones, a crown forged in blood, and a silence that demands reverence.
But what truly makes one a Demon King?
Is it power? Authority? Or perhaps the burden of choosing when to be cruel and when to be kind?
The Demon King is not born—he is made.
In fire. In solitude. In the judgment of those who kneel and those who resist.
He is the one who dared to look into the heart of despair and say, 'I will reign'.
And so he does.

3508 N.C (Noarc Calendar)
In a once-flourishing country now reduced to ruins, a war that could change the fate of the entire world was unfolding. It was a conflict on a scale no one had ever seen or heard of before.
Since the dawn of creation, mankind—made up of various species—and demons had always been at odds.
The reason? No one truly remembers. No one recalls who started it, why it began, or when it might end.
The only certainty is that the world has endured countless wars and relentless destruction. Entire nations have been wiped out because of it.
Now, demons occupy half the world, a region known as the Demonic Continent, which consists of multiple demon nations ruled by a single supreme leader: the Demon King.
The other half is divided into several continents, each home to countries formed by different races or species. It is called the Supercontinent, Eurelia.
This world is called Elarion—a planet seven times larger than Earth in both landmass and oceans.
Currently, a war raged on the outskirts of the Demonic Continent, in a place where a once-prosperous country had flourished for thousands of years. Now, it was nothing more than a memory—just another chapter in a forgotten history.
Seven million people had joined this war, each driven by their own reasons and motivations. Some were selfish, others naive, or even childish to some.
The battlefield had long since crossed the boundary between despair and hopelessness. Lives were lost like broken kites drifting into the unknown.
Death had become the only constant. No one knew who would fall next, as the land was drenched in blood and covered with fallen bodies.
Explosions, the clash of swords, and arrows slicing through the air had become the rhythm of the land.
The Pan-Human Alliance was already at a disadvantage. The demons were pushing them back. To the violent and war-hardened demons, victory seemed just within reach.
"Fire!" a soldier shouted, and tens of thousands of arrows rained down upon the battlefield.
But alas, nearly half were halted midair by magic or other countermeasures. Still, the rest fell upon the demons, cutting them down.
Yet many demons surged forward, tearing through the lines and beheading the soldiers who had launched the arrows. Not even the despair in their eyes could stir the slightest sympathy.
Corpses—both demon and human—piled up, and even those were not spared.
Demonic beasts and monsters had devoured many of the fallen. Some remains were missing limbs, others had lost their heads, and some were reduced to nothing but scattered fragments.
Yet no one had the time to mourn or honor the dead.
The battle had raged on for an unknowable length of time, with neither side showing signs of retreat.
And still, the Alliance held on to hope. They had one final plan. Their trump card—the Hero and her party.
A massive white dragon soared over the battlefield. Riding atop it were the current Hero and her party.
The dragon spewed flames that incinerated any demon bold enough to approach. Skills, Magic Arts, and Noble Arts were commonplace in this war—but the power wielded by those on the dragon was on an entirely different level.
Spells and martial techniques capable of wiping out thousands in an instant were merely the beginning; more intricate and devastating ones soon followed, drawing the attention of everyone fighting below.
"Don't let the Hero pass!" shouts like these echoed as demons scrambled to stop her, while the Alliance did everything to clear her path.
In the distance, a grand castle came into view—the demon headquarters for this war. The Hero assumed the Demon King must be there.
A colossal gate stood in their way, guarded by someone who appeared to be merely a young girl.
But appearances meant little in this world—youth could be deceiving, and body transformation was common.
The dragon didn't stop and flew over the gate. Strangely, the girl did nothing. But as the rest of the Alliance forces neared, the air grew suffocating.
In a calm voice, the girl said, "Leave." Her voice echoed across the battlefield, causing many to collapse and others to freeze, paralyzed by fear. But even after the warning, many didn't stop.
"I said LEAVE! His Majesty hasn't permitted you to enter," she continued.
Still, they didn't stop. Leading them was a commander from one of the human kingdoms. "We don't need anyone's perm—"
Before he could finish, his upper body was vaporized by a laser-like beam from the girl, whose expression barely shifted—mild irritation at most.
The attack didn't end there. It sliced through the soldiers behind him, killing tens of thousands in a single, casual flick of her arm.
The rest fell into despair.
"T-that green hair, green eyes, and that petite body… It's the Demon Lord of Ruin!" someone screamed. The sight of her and that green laser had triggered a long-buried memory.
Panic swept through the soldiers.
The Demon Lords, rank Yodh (rank 10 in the demon ranking system), were the highest-ranking demons under the Demon King (who was also rank Yodh). Each ruled over their own kingdom within the Demonic Continent.
They were the strongest of their kind.
But even among them, the one known as the Demon Lord of Ruin stood apart. Her destructive power and unpredictable nature were legendary.
Wherever she went, ruin followed.
The soldiers turned to flee, but none escaped.
Acid rain began to fall from the sky, melting flesh and armor alike. Cries of agony filled the air as they died in one of the most gruesome ways imaginable. Not a single soul who had ignored her warning was spared.
After the massacre, she simply turned around and walked back inside.
Meanwhile, the white dragon crashed into the palace, tearing through its walls to force entry to the hall.
CoughCough
Dust flew as the ones on the dragon landed on the floor, coughing from the debris caused by the destroyed wall.
"Told ya we'd make it fer sure," said an eldwarf (half-elf, half-dwarf) named Ruther, gripping his axe with a smug grin, proud of his dragon's performance.
He even gave his dragon a hearty slap. "Knew the beast had fire in its belly!"
But suddenly, a massive horde of undead poured in from behind. Everyone tensed as the air grew heavy—these weren't ordinary undead. They were high-ranking, powerful enough to take down even the most seasoned warriors with ease.
As the tension rose, Ruther glanced toward a silver-haired man with red eyes and snapped,
"Oi, pretty face! Ain't it 'bout time ya got off yer ass and did somethin'? How long ya plannin' on hidin' behind yer wifey, huh?"
The silver-haired man was Nael Sara Beltre, a druid and the current Saint of the Goddess of Light's Church. He was also the newly wedded husband of the current Hero, Claudia Sara Beltre, who had been summoned from Japan to this world four years ago.
Claudia had striking features—half of her hair white, the other half a soft pinkish-purple. Her eyes were heterochromatic: the left pink, the right purple. Her beauty was breathtaking.
Sigh
"Don't rush me, old man. I've been boosting everyone—even that dragon of yours—since the start," Nael replied, stepping to the front as he began to chant.
O Light divine, from heavens high,
Cleanse this soul as shadows die.
By sacred flame and holy might,
Burn all taint, restore the right.
Sin and sorrow, fade away,
Let grace and truth alone now stay.
In thy name, O Radiant One,
Let this be pure—thy will be done.
Nael finishes the chant in an instant with his fast incantation, magic circles lighting up the air with divine light as holy power radiates outward. The light instantly purifies all the undead, causing them to vanish into thin air.
"See? Told ya bringin' this fake priest along weren't a waste," Ruther grunted.
Nael gets irritated as the two begin bickering.
"Hey! Look at the time and place! We're inside the Demon King's castle—what are you two doing?!" Claudia yells at them. They immediately stop.
Even though she was shouting, she wasn't truly mad. She knew her husband and their friend were just trying to lighten the mood.
Everyone was stiff and anxious after coming here. Nobody knew how many of them would survive today. But even so, they had to do it—for the sake of ending this wretched war.
As they spoke, a sudden wave of flame rushed at Nael, evaporating the entire left side of his body, catching everyone off guard.
Deirdre—the one with the elongated ears, long, beautiful green hair, and green eyes—immediately shielded the others from the incoming barrage of flames by summoning humongous trees to block the attack.
Even though her element was weak against fire, her trees still stood firm against the flames. Nael's body regenerated instantly with his holy power.
As they reorganized, two demons with single horns on their foreheads—one a red oni, the other blue—burst through the trees to attack. Behind them, a magic circle opened, unleashing a flood of undead.
Ruther intercepted the red oni's punch with his axe, protecting Nael.
"Tch! You really are a Saint. Even getting half your body destroyed didn't kill you?!" the red oni growled, half in exasperation, not expecting a response.
"You two are the twin onis from the Black Death's country, right?" Deirdre asked as she blocked the blue oni's strike.
Both were well-known warriors—rank Teth (rank 9)—serving in the army of the Demon Lord of the Black Death, the strongest dark mage and a necromancer.
"Oh, you know us?" said the red oni, both of them momentarily stepping back. They were about to speak more before fighting, but all of them suddenly sensed multiple powerful auras approaching, cutting through the Alliance's army.
They knew those auras—they belonged to some of the other Demon Lords. If they waited any longer and the Demon Lords arrived, their chances of killing the Demon King would plummet.
Most of the Demon Lords were currently engaged with their own opponents. The Alliance had even brought the Commander of the Elven Kingdom, Eldora, to fight one of the rank Yodh demons, despite the elves remaining officially neutral in the war.
Whatever they planned to do, they had to act fast.
"You lot go on ahead. We ain't got time to waste. Dan (the dragon) an' I'll handle these two," Ruther said, stepping up with his dragon to block the onis.
"Then I'll stay too. It'll be easier to handle the undead with me here," Nael offered.
"Ya need to be there to deal with the Demon King, ya fool!" Ruther snapped back. "Who's gonna heal and back everyone up if yer not there?! I can handle a bunch o' weak undead with me eyes closed!"
Nael couldn't argue. Time was short, and the two onis weren't giving them any breathing room. Their biggest concern was the arrival of the other Demon Lords—if they delayed any longer, it would be too late. So everyone agreed.
"Don't die," Nael said as the rest of the party rushed toward the throne room.
"Heh! Who d'ya think yer worryin' about? I might even get there before the lot o' ya!" Ruther shouted, clashing with the red oni while Dan took on the blue one.
"You sure about that?" the red oni replied as their battle began.
None of them shared names—it wasn't worth the time. To demons, such formalities were meaningless, and besides, they already seemed to know about one another.
As the fight raged behind them, Claudia and her party had to go through traps and enemy soldiers to finally reach the throne room. Outside, chaos reigned—explosions echoed from every direction.
As Claudia opened the door, she stepped into a vast throne room adorned with luxurious decorations. Sitting on the grand throne was a demon whose aura was beyond anything they had ever imagined—impossibly overwhelming, suffocating even.
With his face resting on his arms and his arms draped over the throne, he looked bored, almost disinterested, yet his very presence twisted the air. Dark, ominous red aura surrounded him.
His face was so handsome it bordered on madness, capable of driving both men and women insane.
His long, flowing red hair resembled a lion's mane, and his slender yet muscular body was the kind every man dreamed of possessing.
But it was his gaze—those piercing purple eyes—that truly unnerved them. Just meeting his eyes made it hard to breathe, as though the world itself rejected their existence in his presence.
As soon as Claudia and her party stepped into the throne room, everything changed.
The walls, the chandelier, the lavish decorations—all vanished. In their place was a sky of bright, ominous red.
The space had shifted. It wasn't just the room—it was as if they had been pulled into another dimension entirely.
"Now, nobody will bother us here," the man said. His voice was madness incarnate, the kind that could unravel the mind just by being heard.
'This is space—no, both time and space magic,' Claudia thought, sensing the magical distortions.
Space and time were among the hardest types of magic to ever exist. One could count on both hands the number of people capable of using even one of them; using both was even rarer.
Teleportation was a branch of space magic, and while still rare, there were quite a few magicians proficient in teleportation alone—though that was far from mastering true space magic.
Her Holy Sword, Velnarc, resonated in response. Forged at the end of time and tempered in the forgotten past, Velnarc did not sever flesh, but time itself.
Wounds inflicted by it echoed across all timelines—past, present, and future—permanently etched into fate. No spell, no miracle, no manipulation of time could ever undo its damage unless the wielder willed it so.
It was the strongest sword in existence, a blade that imposed irreversible reality.
As Claudia and her party took in the otherworldly surroundings, they turned to face the being before them—THE DEMON KING.
"So, you're the Demon King," Claudia said, unsheathing Velnarc and pointing it at him, her companions readying their weapons beside her.
"Indeed. I am the one called the Demon King," he replied calmly. His aura exploded outward, filling the space with crushing intensity. The very air trembled.
He was the Demon King of the whole Demonic Continent.
The strongest demon in history.
The Demon King of Annihilation.
Lucien Daeva Asmodeus.
And thus the battle that would decide the fate of the world had just begun.
Trivia:
The prefix 'Pan–' comes from Greek, meaning 'all' or 'including everything.' So 'Pan-Human Alliance' means 'an alliance that includes all of humanity.'
