The sky didn't crack open with thunder.
There was no blinding light, no divine voice announcing the end of everything.
Reality simply… paused.
Aren Kael noticed it first because he was already awake when the world stopped moving.
The cheap digital clock on the wall froze at 02:17. The buzzing ceiling fan halted mid-rotation, its blades hanging in the air as if pinned by invisible nails.
Outside the apartment window, rain hung motionless, droplets suspended like glass beads against the neon glow of the city.
For a single, breathless moment, Aren thought he'd finally snapped.
Then the silence deepened.
Not the quiet of an empty room—but the absolute absence of motion, sound, and time itself.
Aren sat up slowly on his narrow bed, heart pounding. His body moved easily, too easily, as if the rules of inertia had loosened their grip on him.
He swung his legs over the side, bare feet touching the cold floor.
Everything else remained frozen.
"Okay," he muttered, voice sounding unnaturally loud in the stillness.
"Either I'm dreaming… or I'm about to die."
Neither option felt particularly comforting.
Aren had lived an ordinary life. No tragic destiny. No hidden bloodline. Just an eighteen-year-old scraping by in a city that didn't care whether he existed or not.
If the universe was choosing people for something grand, he was pretty sure he wasn't on the list.
That was when the air folded inward.
It didn't tear or shatter. It bent, like a sheet of invisible glass being slowly warped by unseen hands.
Lines of faint silver light etched themselves into the space before Aren, forming a circle layered with symbols he didn't recognize—but somehow understood.
The circle pulsed once.
Then a voice spoke.
Not aloud. Not inside his head.
It resonated directly within his existence.
[Convergence Event Detected.]
Aren staggered back a step, nearly tripping over his bed.
"Yeah, no kidding," he said, forcing the words out.
"Care to explain before I panic?"
The circle brightened.
[Prime Reality Integrity: Failing.]
[World Fragments Initiating Merge.]
[Survivability Check: Commencing.]
The temperature dropped. Aren felt it in his bones, a creeping cold that had nothing to do with heat.
"What does survivability check mean?" he asked.
The circle didn't answer.
Instead, the room collapsed.
Not physically—but conceptually.
The walls stretched away, dissolving into layers of overlapping scenery. A battlefield drenched in blood flickered into view.
A towering academy spire replaced it, only to shatter into digital grids of floating numbers.
A colossal shadow crossed a crimson sky, followed by the sterile interior of a metal cockpit filled with blinking lights.
Worlds overlapped, clashing like broken reflections forced into the same mirror.
Aren dropped to one knee, clutching his chest as pressure crushed down on him from every direction.
His vision blurred. His heartbeat thundered in his ears.
He felt rejected.
Not by people—but by reality itself.
Every fragment he glimpsed carried its own rules, its own laws, its own way of defining existence. And every one of them screamed the same message at him:
'You do not belong.'
Pain lanced through his body as invisible forces tried to tear him apart—pulling him in incompatible directions, each world demanding he conform or be erased.
"Is this it?" Aren gasped.
"I don't even get a chance?"
His muscles seized. His thoughts began to scatter. He could feel something inside him cracking, splintering under the strain.
Then—
Something answered.
Not the voice.Not the circle.
Deep within Aren's chest, beneath fear and instinct, something stirred. It wasn't power. It wasn't knowledge.
It was —adaptation.
A pulse radiated outward from his heart, silent yet absolute. The pressure eased—not because the worlds withdrew, but because Aren changed.
His existence shifted, fluid and responsive, reshaping itself to fit the impossible conditions being forced upon it.
The pain didn't vanish—but it became manageable.
The rejection faltered.
[Anomaly Detected.]
[Existence Stability: Recalculating.]
Aren sucked in a ragged breath. His vision cleared just enough to see the silver circle flicker erratically.
"What… did I do?" he whispered.
The answer came, colder and sharper than before.
[Adaptive Origin Core: Detected.]
[Status: Dormant → Awakening.]
Something clicked into place.
Aren felt it then—a presence within him that hadn't existed moments before. Or maybe it always had, waiting for a moment when it was needed.
A core.
Not a physical organ, but a conceptual anchor. It absorbed pressure, translated incompatible laws, and restructured his existence in real time.
The clashing worlds recoiled.
Not in fear—but in confusion.
[Warning: Subject is not rejecting incompatible systems.]
[Warning: Subject is not being rejected.]
Aren let out a shaky laugh that bordered on hysteria.
"So… we're all confused together, huh?"
The overlapping visions sharpened, stabilizing into something resembling coherence. One world took precedence—a ruined urban landscape lit by flickering signs and distant fires.
This one felt… closest.
[Initial World Anchor Established.]
[Designation: Shōnen Combat Fragment.]
The silver circle rotated, symbols rearranging themselves.
[Survivability Check: Passed.]
Aren's knees buckled as the pressure vanished completely. He collapsed onto what was no longer his apartment floor, but cracked asphalt stained dark with dried blood.
The frozen rain resumed—except now it fell as ash.
Sirens wailed in the distance.
He lay there, chest heaving, staring up at a sky fractured by glowing scars that pulsed like open wounds.
"So," Aren said weakly,
"I'm alive. That's new."
The circle dimmed, hovering above him like a watchful eye.
[Adaptive Origin Core: Initial Parameters Unlocked.]
A translucent interface unfolded before his eyes—minimalist, sharp-edged, and unmistakably not human-made.
———————————————————————————————————————
Name: Aren Kael
Existence Tier: MortalCore
Status: Dormant (Awakening)
Stability: 61%
Compatible Energy Types: Undetermined
Primary Trait: Absolute Adaptability
———————————————————————————————————————
Aren stared at the last line.
"Absolute adaptability," he repeated.
"That sounds… dangerously vague."
As if responding to his skepticism, new text appeared.
[Absolute Adaptability allows subject to survive, learn, and evolve under incompatible laws.]
[Adaptation requires exposure and survival.]
[Failure results in instability, corruption, or erasure.]
"…Of course there's a catch."
A distant explosion rocked the ground. Aren flinched, instinctively rolling to his side as a shockwave rippled through the street.
He scrambled to his feet, ignoring the ache in his limbs. The city around him was in ruins—buildings shattered, vehicles overturned, scorch marks lining the walls.
Figures clashed in the distance, moving too fast, striking too hard to be normal humans.
Energy flared with every impact.
Aren felt it then—pressure, heavy and sharp, rolling off the fighters like heat.
'Combat Energy.'
His Core reacted instantly.
A faint warmth spread through his chest, subtle but undeniable.
[Exposure Detected: Combat Energy.]
[Adaptation in Progress…]
His breath caught.
"You've got to be kidding me," he muttered.
A scream echoed nearby—too close.
Aren turned just in time to see a body crash through a storefront, skidding across the street and coming to a stop a few meters away.
The man groaned, trying—and failing—to stand.
Three figures advanced on him, their auras flaring violently.
Aren's instincts screamed at him to run.
He was weak. Untrained. Barely holding himself together.
But the Core pulsed again, sharper this time.
Not urging him forward.
Just… waiting.
"If I don't get involved," Aren said quietly, "do I die later anyway?"
The interface didn't answer.
The world did.
One of the attackers glanced in Aren's direction, eyes narrowing.
"Another one," he sneered.
"Guess today's my lucky day."
Pressure slammed into Aren like a wall.
His Stability dropped—58%.Then 55%.
Panic clawed at his chest.
"No! No! Not like this."
He took a step back—
—and felt something lock into place.
His Core flared, threads of energy weaving through his muscles, crude and inefficient but there.
[Minor Adaptation Complete.]
[Combat Energy Compatibility: 3%]
Aren clenched his fists, feeling strength he shouldn't have. It wasn't much—but it was enough to stand.
Enough to choose.
He raised his head and met the attacker's gaze, heart pounding but eyes steady.
"Hey," Aren called out, surprising himself with how firm his voice sounded.
"If you want to kill someone today…"
The Core pulsed.
"…you'll have to start with me."
The sky rumbled overhead, glowing scars widening as if reality itself were watching.
And somewhere beyond the fractured heavens, something ancient took notice.
'The Convergence had found its anomaly.'
