The world was not always as we know it.
There was a time when chaos reigned supreme.
Colossal beasts—living incarnations of the primordial elements—ruled with a ferocity beyond imagination.
So powerful were they that even Erebus, the god of creation and balance, feared to face them.
Under their shadow, mortal races were nothing more than fragile echoes, condemned to a desperate struggle for survival.
In those days, everything revolved around Elemental Energy, an ancient force that flowed through the very essence of existence.
For mortals, it was but an unreachable spark.
For the beasts, it was a natural extension of their power.
Where they walked, mountains rose, oceans raged, and storms unleashed their fury.
To Erebus, these creatures were more than a threat.
They were chaos incarnate, a direct affront to his creation and the balance he had sworn to protect.
He could not stand idle.
Filled with sorrow, the god descended to the world to face them.
The battle that followed was like no other.
The skies were torn asunder, and the earth trembled beneath the magnitude of their clash.
But even Erebus could not destroy them.
They were too powerful.
In the end, he found a solution.
Using his divine power, he severed the souls of the beasts from their bodies, sealing them away in prisons that existed beyond time and space.
With this, the world was freed from their threat.
But the cost was great: Erebus was weakened, and the earth itself bore the scars of his sacrifice.
With the beasts gone, an era of prosperity dawned.
Mortals built kingdoms, explored the secrets of Elemental Energy, and lived in peace.
But that peace was not eternal.
From the shadows emerged the demons, a ruthless race led by the dreaded Demon King.
With him marched the Akumas, mindless savage creatures, and his most feared generals:
The Seven Angels of Death.
The darkness they brought was devastating.
One by one, the kingdoms fell beneath their assault, leaving behind a world stained with blood and despair.
Desperate, the mortals cried out to Erebus once more.
Though weakened, the god heard their plea.
But this time, there were no beasts to slay—no easy solution.
He was still too frail.
So he made a drastic decision:
He sacrificed what remained of his divinity and, with it, forged the first Reikens.
Swords imbued with fragments of the souls of the beasts he had once fought and sealed.
Weapons that granted their wielders unimaginable power.
With the Reikens, mortals finally had hope.
But the Demon King, cunning and merciless, was quick to retaliate.
He captured Erebus and forced him to forge Reikens for his own army.
These weapons were corrupt…
Tainted by darkness.
Once they were complete, Erebus was executed without mercy.
What followed was a war unlike any other:
Reiken against Reiken.
The battles brought the world to the brink of collapse.
The demons seemed unstoppable…
Until an unnamed warrior—a hero—rose to lead the resistance.
His skill and valor rivaled even the Seven Angels of Death and the Demon King himself.
With other Reiken wielders at his side, he faced the demonic forces in a final battle that shook the foundations of creation.
In the end, the Demon King and his Seven Angels of Death were defeated.
And the demons were banished to the barren wastes of the Eternal Shadows…
A place where light never reaches.
Yet victory came at a steep price.
Many Reikens were lost.
The unnamed warrior fell…
And his Reiken vanished into oblivion.
The survivors learned a bitter lesson:
Peace is never eternal.
That is why they dedicated themselves to training new generations of warriors,
keeping the legacy of the Reikens alive.
Now, over ten thousand years later…
The world seems to have forgotten that war.
But the scars of the past never fade.
And peace…
Is never eternal.
