Dark and gloomy, the sky crumbling.
A place far from the core realms of the Gods and Demons Continent—far beyond the reach of even the Celestial Sect or the Five Great Shinobi Nations.
This land remains cloaked in darkness throughout the year. The heavens hang heavy, pressing down as if mirroring the suffocating weight of spiritual suppression and corrupted chakra.
A crimson blood moon looms in the blackened sky, casting a sinister glow across the void.
Black strands of malevolent energy—twisting torrents of Yin-Yang corrupted chakra and residual Demonic Haki—sweep through the land like a cursed wind from the Nine Hells.
The ground below is carpeted with bone.
Skeletons clutching rusted katanas, broken kunai, shattered seastone spears, some adorned in shattered shinobi or samurai armor, others in Marine cloaks and devilish pirate garb—silent remnants of an ancient war. All lay entombed beneath layers of death.
Still. Cold. Unyielding. Forgotten.
No language captures the horror here.
This place is forbidden. Neither ninja nor pirate nor sage dares approach.
And at the edge of this wasteland—
A towering throne constructed of bleached bones.
There, enthroned upon it, sat a withered figure wrapped in swirling black aura, dense with demonic will, corrupted chakra, and hints of Armament Haki so ancient it had calcified into pure killing intent.
Emaciated and hollow-cheeked, his skin rotted like parchment, clinging tight to bones.
His hair was ash-grey straw, tangled and lifeless.
But his eyes—oh, his eyes—glowed with something terrifying: a timeless emptiness, ancient as the Sage of Six Paths, indifferent as Im-sama's stare.
He had not moved for eons.
He sat in silence, as the dead would, save for the currents of Life and Death Energy—black and white chakra—that spiraled about him like the Edo Tensei resurrection smoke. They blended, churning into a dead, merciless grey.
He was the Ancestor of All Demons, once known in some distant age as the Demon King of the West Sea, the entity that wielded both the Yin-Yang Release and Advanced Conqueror's Haki at their peaks.
Time could not erode him. Even the will of the world, the Heavenly Dao or the World Government's cosmic balance, could not destroy him.
Let the moon fall. Let the Sage Tree rise again. Let Joy Boy awaken.
He remained: the Immortal Demon Sovereign.
Even without a battlefield, even without clashing swords or jutsu or haki bursts, the sheer pressure of his existence crushed the hearts of all who watched through the Gold List's projection.
"Is this... the Gods and Demons World?!" someone whispered across the realms.
"Tenth-ranked my ass—this place should be top five!"
"Just the first glimpse—the Demon Sovereign's presence—froze my chakra flow!"
"Why is he alone in that cursed land?"
"He's going to start a war, I can feel it in my Haki!"
In the heavens and across the worlds, from Mariejois to Konoha, from the Moon Realm to Fishman Island, awe spread.
The Purple-Gold Ruffian Dragon—a rogue Celestial Dragon expelled for using Conqueror's Haki—shouted:
"HAHA! That's OUR world's demon lord! He's our number one seed!! You all better prepare to kneel!"
Even on the heights of Da Luo Sacred Mountain in the Universe Realm, Quasi-Emperor Xuanba—holder of the Destruction Dao Law—narrowed his eyes.
"This aura... is not far from my own. A kindred will in rebellion..."
Then—
The second scene opened.
"Heavenly Dao… You are no longer the will of all beings. You are bloated with desire and must be cleansed."
The Demon Sovereign stirred. Slowly, he rose from the bone throne.
As he did, the heavens quaked.
Massive thunderbolts—judgment-level Divine Tribulation Lightning, the kind that once obliterated Uchiha Madara's Susanoo—tore open the sky.
Heavenly Dao's fury descended. Punishment was imminent.
Yet, the Demon Sovereign merely extended both arms, as if to embrace the broken sky.
Eyes closed, he whispered:
"I have waited long enough... for this moment."
BOOM!!!
His eyes snapped open—eyes that once saw the Void Century and the sealing of Kaguya Ōtsutsuki.
He looked down upon the endless field of bones and uttered:
"Old comrades… awaken. Rise once more."
Crrraaack!
Crrraaack!
The land split apart. The forbidden zone trembled.
From beneath the earth, skeletal hands burst upward.
ROAAAR!!
One undead warrior clad in cracked Onigashima armor surged upright, roaring as a cursed war blade gleamed in his hand.
"KILL!!!"
The shriek triggered a chain reaction.
Millions of slumbering dead—shinobi, samurai, pirates, admirals, celestial warriors, even fallen tailed beasts in skeletal form—rose.
"KILL!!"
"KILL KILL KILL!!!"
Their cries turned into a spiritual shockwave, fracturing clouds and space itself.
Their killing intent pierced dimensions. Even Akainu dropped his cigar.
Even Madara's Edo clone, watching from the afterlife, shivered slightly.
The Demon Sovereign smiled—eyes burning with ancient battle fury.
He laughed to the sky:
"Excellent!"
"Let the dead serve as my soldiers. Let the gods and demons of antiquity be my generals!"
"If the heavens have turned corrupt—then I shall dye the skies in demon blood! Yin and Yang be reversed! Destiny, be shattered!"
CLANG!!
He unsheathed a throne-blade—the legendary Blade of Void Mara, once wielded by a pirate god-killer in the Void Century. Rusted and red, it still reeked of Im-sama's kin's blood.
With one slash, he planted it into the soil.
"NOW!!"
"Warriors of death, with me!! DESTROY THE HEAVENS!!"
"KILL!!!"
"KILL KILL KILL!!!"
"KILL KILL KILL KILL KILL!!!"
A tide of undeath surged as the Death Jedi cracked. Entire ridgelines exploded. Spiritual pressure flattened forests 3,000 kilometers away.
And thus, the Demon Sovereign led his army—an army of legendary corpses, of demonic gods, and broken-world heroes—into rebellion.
Aimed at the heavens themselves.
---
Across realms, chaos erupted.
"He's trying to KILL the Heavenly Dao!?"
"This man's going to war with the law of existence!"
"The tenth-ranked world is INSANE!"
"A hundred million soldiers! A million general-level combatants!! Even the World Government can't match that!"
"Mad... utterly MAD! Even Joy Boy only challenged the Celestial Order—this man is declaring war on all planes!!"
On Da Luo Mountain, Xuanba grinned broadly.
"HAHAHA! Forget his strength—his rage, his madness—that's a man of my heart!!"
