It had been eighteen years since Kael drew his first breath in this world.
Eighteen years since his rebirth.
Yesterday, the fragments of his past life had finally returned—
the life of Eidolon Lvl. 0, the forgotten shadow who once walked between worlds.
And along with those memories… came the System.

Kael stared at the glowing blue panel hovering before his eyes.
It pulsed faintly, like a heartbeat synced to his own. The air around him felt heavier, charged with quiet power.
A strange calm washed over him—half nostalgia, half dread.
So it's finally begun, he thought, fingers curling into a fist.
This world… this cursed world of Jujutsu.
The wind whispered through the tall cedars of the Tokyo outskirts. The forest stretched endlessly behind him, the city lights shimmering far below the hill. For years, he had lived in solitude here—hunting cursed spirits, surviving on scraps, waiting for the echo of his lost self to return.
Now, that echo had answered.
Kael tightened the strap of his black jacket, eyes cold and unreadable. His reflection in the water's surface looked unfamiliar—white hair tipped in silver, sharp eyes gleaming with an ancient chill.
He wasn't human. Not fully.
The Ackerman blood within him thrummed like restrained lightning. The Kaguya bone beneath his skin itched with dormant power.
He was a contradiction stitched from two worlds that should've never met.
…
That was when the air shifted.
A ripple—soft but immense—brushed against his senses. Space itself bent for a heartbeat.
"Hey. What are you looking at?"
The voice cut through the silence—lazy, teasing, but laced with something sharp.
Kael turned.
A man stood at the edge of the clearing, tall and annoyingly casual. White hair glowed faintly beneath the sunlight, and a blindfold covered his eyes. Yet even through that cloth, Kael could feel the gaze piercing through him, dissecting every secret down to the marrow.
That grin. That pressure.
There was no mistaking it.
Gojo Satoru.
The Six Eyes user.
The strongest sorcerer of this world.
The one honored by the heavens.
Kael's heartbeat quickened. His system pulsed again, flickering with a faint warning.
[Caution: Target's Power Exceeds Measurable Threshold]
Gojo tilted his head, smiling wider.
"Interesting. You've got quite the aura, kid. Who are you supposed to be?"
Kael's lips curved slightly—neither smile nor smirk, but something colder.
"Just a ghost," Kael said softly, eyes narrowing, "who finally remembered how to live."
…
He wasn't lying.
Kael had never been meant to exist.
He came into this world screaming beneath a crimson sky, in a forgotten ruin swallowed by curses.
No doctors. No prayers. No gentle hands.
Only shadows… and the stench of death.
His mother—a cursed womb bearing a fragment of malice.
His father—a desperate exorcist who tried to destroy her before she gave birth.
Both were devoured by the curse the moment Kael emerged, leaving behind only blood, bones, and the wailing of a newborn.
The curse lingered, feeding on the despair of the dead.
And yet, the child did not cry for long.
He stared at the darkness… and the darkness stared back.
…
From the moment he could crawl, Kael's body was wrong.
His skin cracked. His bones itched beneath his flesh as though alive, whispering to be freed.
And one night, when pain and hunger fused into madness—he obeyed.
Crack.
Ivory blades burst from his arms. Blood streamed down his tiny frame as the floor trembled beneath the surge of cursed energy.
The monster that haunted his cradle lunged—and Kael met it with bone and fury.
When it screamed, he didn't stop.
When it begged, he didn't listen.
He tore it apart, piece by piece, until there was nothing left but silence and dust.
Then… he ate.
Flesh, essence, curse energy—it all melted into him like poison and fire.
And in that agony, Kael Eidric was truly born.
…
The following years were chaos.
He grew up amid rot and ruin, learning to shape his bones into weapons—spikes, blades, shields. The more he bled, the stronger they became. His every wound carved him closer to perfection.
Each meal was a battle.
Each breath was survival.
His hair turned pale, drained of color.
His eyes, once dull, gleamed red like burning coals—half human, half curse.
Whispers began to spread across the underworld.
A boy who devoured curses.
A monster that walked like a man.
They called him The Curse Eater.
Others, in hushed awe, whispered another name—
Eidolon.
…
The weak hunted him to erase a threat.
The strong hunted him to test their worth.
None succeeded.
Sorcerers sent after him vanished without a trace.
Curses that dared approach him were reduced to bones.
Blood, smoke, and silence followed wherever he went.
Until one day—
as Kael stood atop a mountain of dead curses beneath a sky split with thunder—
a figure appeared.
Calm. Careless.
White hair brushed the wind, the blindfold fluttering lightly.
Gojo Satoru.
The Six Eyes shimmered behind that black cloth, dissecting every atom of Kael's existence.
And for the first time in years, Kael felt his instincts scream—
not in fear…
but recognition.
The air warped around Gojo, heavy and suffocating. Each breath Kael took felt like inhaling lightning.
"Hey," Gojo said, his voice a blend of amusement and curiosity, "you're quite the anomaly."
He smiled like he'd just discovered a riddle that shouldn't exist.
Kael stared back, his crimson eyes reflecting the faint glow of the city far below.
That was the moment—
the night everything returned.
His name.
His past life.
The System.
And the cruel truth that this world was none other than Jujutsu Kaisen.
Gojo Satoru—
the strongest of this era.
Kael had expected him to come sooner or later.
…
"Hello," Kael said finally, raising a hand with a small, innocent wave.
His tone was soft, but the smile on his lips didn't reach his eyes.
Gojo blinked, then let out a short laugh.
"Hah! Cute," he said, tilting his head with that familiar smugness. "Didn't expect manners from someone radiating cursed energy like that."
"What's your name, kid?"
"Kael," he replied. "Kael Eidric."
Gojo's grin widened. "So you do have a name. That's good. Makes it easier to remember the people I beat up."
Kael's gaze sharpened. "You want to fight me?"
Gojo shrugged, light as air—but the ground beneath them trembled.
The air turned thick, humming with invisible pressure. Birds scattered into the night.
In that instant, Kael's instincts roared. His bones stirred under his skin, eager and wild.
This man is broken, he thought. Even in my prime, I wouldn't take him lightly.
For a heartbeat, neither moved.
Only their energies collided—two storms twisting the air itself.
Then, just as the tension peaked—
Gojo laughed. "Nah."
He brushed imaginary dust from his sleeve and turned.
"Let's not do that here. Follow me."
Kael didn't move. "Why?"
Gojo looked over his shoulder, blindfold shifting slightly as if his gaze burned straight through the fabric.
"Because if we fought now," he said, grinning, "half this district would vanish—and I kinda like Tokyo the way it is."
He began to walk away, calm and sure.
And for reasons Kael couldn't quite explain…
he followed.
