[Somewhere between heaven and hell]
Ash rained from the sky like black snow.
The battlefield expanded endlessly, spanning beyond the world itself into the vast reaches of the galaxy.
War has consumed the Universe!
On one side stood a grand alliance—the last hope of the mortal and celestial races. Humans clad in enchanted and Divine steel. Elven archers and sorcerers with arrows wreathed in silver flame. Dwarven berserkers shouting war cries in their deep tongue. Dragons soared over planets, wings covering up an entire planet, their roars shaking the cosmos. And at their center stood the radiant hosts: the Angels.
The alliance roared in response. Millions of voices became one.
And then came the darkness.
The demon legions surged forward like a living tide—snarling, screeching, hissing. Succubi with crimson wings glided across the skies, trailing whispers of lust and despair. Incubi led frenzied charges of corrupted beasts. Shadow demons slithered between dimensions, blinking in and out of view. Vampires danced through the air with blood-soaked blades, while werewolves howled their hatred to a broken moon.
A beastkin war maiden—a fox-kin with ember eyes—screamed in fury, leaping into the fray with twin katanas. Behind her, cat-kin scouts and boar-kin warriors followed, their claws and axes eager for blood.
The clash came like a storm.
Steel met fang. Flame met frost. Light met shadow.
The battlefield became a chasm of chaos.
..................
A hundred thousand years later...
[World of humans, Humanitus]
The grass was soft beneath their feet.
In the garden of a grand mansion—styled like something from the age of kings, yet humming quietly with magic-forged machines—three children played beneath the watchful gaze of the midday sun.
Laughter filled the air.
A little girl, no older than ten, dashed across the garden path with reckless joy. Her silver hair fluttered behind her like silk ribbons, and her small ruby-like red eyes sparkled with delight as she squealed with glee.
Chasing her was a boy—twelve years old, with the same silver hair but eyes of glittering gold that seemed to reflect more than just sunlight. He was fast, determined, and laughing like the happiest child.
Trailing slightly behind them was their older sister, fourteen years old, matching the same enthusiasm as them. Her jet-black hair and crimson-red eyes mirrored those of her father, and though she ran more slowly, her smile carried a quiet warmth.
Three uniformed maids stood nearby, observing with fond smiles and a few worried glances. Their eyes stayed sharp, their posture alert, but they didn't intervene. The children were happy. That was enough.
This was their daily routine to stand guard and keep an eye on them.
Then—without any warning—the world shook and the sky cracked right above their heads.
A bolt of black lightning tore down from the cloudless sky.
It struck the silver-haired boy in an instant.
There was no time to scream. No time to move. The light swallowed him whole—and then he collapsed.
The air trembled.
For a single breath, silence fell like a blanket. Even the birds stopped singing.
The three maids were frozen as if their training was for nothing to save their young master from harm's way.
Then chaos erupted.
The youngest girl fell to her knees, screaming. The eldest sister stood frozen in shock. The maids rushed forward in panic, their training barely keeping them focused as panic flared across the estate.
The boy didn't move, ground beneath his feet was charred and formed a crater around him. His body was charred too and was sparking the remaining lightning around him, he looked miserable and appeared dead.
He was standing still for a few moments as a result of instantaneous neurological and muscular damage, effectively "freezing" the boy in place. His body trembled once… then stilled.
His eyes, once full of life, stared upward—glassy, fading.
The world tilted around him, colors blending into shadow.
And in the final moments of his consciousness, he saw her.
His mother.
She ran across the garden with no grace, no noble poise—only raw terror in her eyes. Her long silver hair flew behind her like wings, her voice shattered by panic as she screamed his name.
"SHIN!!"
The boy wanted to reach for her—but his fingers didn't move.
His vision blurred.
The twelve years old Shin was a moment away from death, however he heard a sudden mysterious sound alongside his mother's scream...
She froze as she watched him dying right in front of her. Her breath caught, lips parting while her eyes widened, unable to blink or look away. The color drained from her face, her chest tightening with shock and helplessness, and all she could do was stare as the moment unfolded.
Then… silence.
..................
In the endless, lightless void where no living soul had ever trespassed—and from which none could ever return—five ethereal presences stirred after countless millennia of silence.
The first voice, ancient and resonant, broke the stillness like a fracture in reality itself:
"Sisters… we have finally found it. The one thing we have sought across the ages."
A second voice followed, laced with desperate hunger:
"Our final hope… the last thread that could grant us what we crave. We cannot allow this chance to slip away."
Then came the third, her tone dripping with sultry, dangerous promise, thick as forbidden nectar:
"I will pour every fragment of my being into this. No holding back. This time… it is do or die."
The remaining voices rose in unison, cold and resolute, sealing the pact with chilling finality.
All seven had agreed. This time, they would go all out—risking the very thread of their existence.
For these seven women were neither alive nor dead. They simply… existed. Suspended in the abyss between oblivion and eternity, clinging to a fragile half-state that could unravel at any moment. Yet for this one, singular opportunity, they were willing to gamble even that.
Then—
[Ding!]
