The darkness didn't open.
It tore.
Like a curtain stretched too tight finally ripping in one violent snap.
Kael inhaled sharply, breath strangled, throat burning.
A sharp pain shot through his neck — an echo of the blow Belzebuth had delivered.
His body refused to move at first, heavy, numb, as if someone had poured molten lead into his limbs.
A wave of dizziness washed over him.
His vision returned in fragments:
a cracked platform,
dust hanging midair,
the taste of iron in his mouth.
Then his breathing quickened.
His heart hammered too fast, too hard, as if trying to make up for lost beats.
And finally…
his gaze fell on the world around him.
Gravyor, collapsed against a wall, chest torn open by a strike no one should have survived — yet by some miracle, he still breathed.
Kiyoshi, sprawled face-down on the stone, unconscious but alive,
a streak of dried blood across his cheek.
Even the air felt too heavy, too still.
Kael forced his fingers to move.
They trembled.
Not from anger.
From shock.
He was about to try lifting himself when—
A sound tore through the air.
Wet.
Metallic.
A sound you never mistake:
Flesh opening.
His gaze snapped up.
And everything froze.
Veda.
Right in front of him.
On her knees.
Frozen by fear.
And behind her…
A monster draped in shadow, wearing the faintest impression of Adam's face — one arm raised,
five claw-blades longer than its hand,
sharp as infernal mirror shards.
The claws pierced her.
All five.
Cleanly.
Straight through.
The impact made her shake, her mouth opening as if searching for air she would never catch.
Kael no longer felt his own breathing.
Time lost its shape.
— …Veda?
His voice was a broken whisper.
Blood burst out.
Red.
Vivid.
Violent.
It splattered onto the ground, arcing perfectly before falling.
Two drops landed on Kael's face.
Warm.
Alive.
She barely managed to open her mouth — a faint smile despite everything:
— Thank you… you're okay…!
The world snapped shut.
All sound vanished.
No more pain in his neck.
No more weight.
Just one word pounding through his head:
No.
Drink.
Kael's pupils contracted until nearly disappearing.
A shiver shot up his spine so violently it tore the air from his lungs.
His heart slammed against his ribcage as if it wanted out.
One beat.
Two.
Each stronger than the last.
His black aura shook, cracked, then split open like an animal waking inside a cage too small.
The air vibrated around him.
Umbra — curled within Kael's shadow — understood first.
And trembled.
Not through thought.
Not through logic.
Through instinct.
Primal.
Absolute.
Ancient.
The kind of instinct that doesn't hesitate.
The kind that screams:
RUN.
RUN FROM HIM.
NOW.
The shadow quivered and retreated desperately into the tattoo, seeking safety.
Umbra curled up — and then his whole body contracted at once, like a trapped beast realizing the true danger wasn't the enemy in front…
but the master behind.
— Gyah… gyAH—!
It wasn't a normal scream.
It was pure terror.
It ripped itself out of Kael's tattoo, torn free like a mass of shadow expelled by a volcano.
The transfer was so abrupt the stone beneath them vibrated.
Umbra didn't even look at Kael.
He didn't dare.
Every fiber of his being screamed the same truth:
Do not stay. You will die.
Umbra lunged.
Not in a straight line — in frantic zigzags, like a panicked shadow fleeing a predator it must not even see.
He threw himself toward Veda.
She hadn't even collapsed yet when shadow-arms wrapped around her — one, then two.
Then, with a wet crack, a third arm burst from Umbra's back, ripping his own shadow-body but without hesitation.
Three arms.
Three bodies.
Veda.
Kiyoshi.
Gravyor.
He grabbed them with desperate, animal strength, lifting them as if they weighed nothing despite their wounds.
Umbra shot across the ground, dragging the three injured bodies like a beast gone mad with fear.
He couldn't breathe — but everything in him mimicked a living creature's panic.
His only goal: hurl them into the portal before Kael finally exploded.
He extended one shadow arm.
Then two.
Then three.
He flung Veda toward the opening, dragged Gravyor by the waist, shoved Kiyoshi forward—
The portal flickered.
A bluish glow — stable, open—
Until it changed.
Abruptly.
Violently.
The light turned red.
Not the red of an error.
Not the red of danger.
The red of absolute prohibition.
Umbra froze, three bodies still clutched in his arms, his aura thundering like an animal heart as he healed and shielded them as best he could.
Then a voice fell.
Not behind him.
Not ahead.
Everywhere.
— You thought it would be that easy?
The tone was neutral.
Too neutral.
Almost administrative — but dripping with irony no demon would bother with.
— Now that I finally have a bit of entertainment, the voice continued,
I'd like to keep my tiny remaining audience, obviously.
A translucent silhouette materialized before the red portal.
Not threatening.
Not aggressive.
Just… present.
Present enough to remind them of a fundamental truth:
No one leaves a floor unless the acting Guide — the current administrator — authorizes it.
He looked at Umbra without moving a single facial muscle, as if observing from another plane, another time.
— System order, concluded the Replacement.
— Escape route temporarily suspended.
The portal locked.
With a sharp sound.
Final.
Irrevocable.
Umbra trembled.
A cold fear crawled up through every tendril of his shadow-spine.
He wasn't running from the Replacement.
He wasn't running from Belzebuth.
He had just realized he couldn't run at all.
The stone cracked beneath his claws.
Umbra leapt back, dragging a black streak across the floor.
He fled from Kael.
Because what he felt in his master's aura…
was no longer power.
Nor rage.
Nor magic.
It was something that should not exist.
Something even shadows refused to serve.
Umbra vanished into a cloud of darkness, hauling the three bodies behind him, determined to hide them before Kael…
became what he was becoming.
A growl rumbled through Kael's throat.
— Not her.
Something cracked deep inside his chest.
Not a bone.
Something else.
Something he'd been holding back too long.
A fissure in the soul.
Then…
Something dropped.
Not in his body.
Deeper.
As if a chain was being released into a bottomless well.
A voice rose with it.
Not a whisper.
Not a scream.
A breath.
— Ah…
She had been there all along.
— Finally.
Kael's body locked up.
His breath hitched.
His heart skipped a beat.
Then one sharp crack split through his ribcage.
Dry.
Violent.
Inhuman.
A rib snapped clean.
— GHAA—AAAH—!!
The scream tore itself out of him — raw, twisted, mangled by agony.
A stream of black Magia poured from his right eye, sliding down his cheek like a burnt tear.
Another rib broke.
Then another.
Then another — as if something inside were crushing his chest to make room.
The voice returned inside his mind.
Calm.
Clear.
— Hurts, doesn't it…?
Kael clenched his teeth.
Pain lit his spine on fire.
His back arched in an impossible angle.
— Get… out…!
Get out of there…!
The words shattered in his throat.
He didn't know if he screamed them aloud or not.
The voice smiled.
— I'm already here.
A shiver crawled up his neck.
His vertebrae cracked one after another, like beads breaking on an overstretched string.
The aura erupted.
Black.
Red.
Two colors that had no business coexisting.
Tendrils of energy spiraled into the air, sucking light toward him.
Far away, Umbra froze mid-movement, tightening his shadow-arms around Veda, Kiyoshi, and Gravyor as he half-healed them.
— Gyah…
He looked at them.
Then at Kael.
And for the first time…
even a shadow hesitated.
On the platform, Belzebuth stopped smiling.
His chin lifted slightly.
— Oh…?
He hadn't moved a single inch.
But his interest had shifted.
At the portal, the Replacement squinted.
His translucent face tightened as if receiving data he didn't understand.
— Magia anomaly…?
No… that's not… it.
A stream of alerts flashed through his invisible interface.
[ Alert: internal Magia levels abnormal. ]
[ Alert: Anima structural modification detected. ]
[ Alert: no protocol found. ]
— …What?
His voice cracked barely.
At the center, Kael burst.
Not literally —
but his body gave way.
His shoulders popped out with sharp cracks, his clavicles dislocating, his shoulder blades twisting under the skin as if searching for a new orientation.
— STOP—!
This time it was out loud.
A command hurled into empty space.
The inner voice laughed.
A simple laugh.
Almost cheerful.
— You called me.
Kael laughed.
Not because it was funny.
Because his mind didn't know what to do with this level of pain.
A hysterical, broken laugh, sounding like ruin echoing through a cavern.
— Hah… ha… hahaha… ah… ah—AARGH—!!
The laugh twisted into a scream.
The scream into begging.
— I… I don't want this…! Stop… stop this…!
His hands clamped onto his own torso as if trying to hold back something forcing its way out.
His nails cracked.
Then regrew instantly — five centimeters longer, translucent, razor-sharp.
Gravyor opened his eyes first.
His vision swam.
His ribs burned.
But even half-blind, he felt it.
— …What… is that…?
Kiyoshi stirred, a strangled groan escaping him.
— Ka… Kael…?
Veda — still impaled, half-held by Umbra — opened one eye.
Her breath whistled.
She didn't understand what she was seeing.
But she recognized one thing:
The sound of Kael's suffering.
She extended one trembling hand toward him.
— …Ka…el…
Her voice vanished under the next fracture.
Kael's sternum split.
Then shattered like a door kicked open from within.
A geyser of black Magia burst from his chest, spilling into the air in dark filaments mixed with red shards of blood.
Black Magia tears streamed from both his eyes now, trailing scorch-marks over his skin.
The inner voice leaned closer.
— You feel it…?
— I… don't… want… this…!
— Too late.
His head jerked backward as if pulled by invisible strings.
His neck dislocated, then snapped back into place at a slightly wrong angle.
Kael's hair twitched — then its color broke.
The black split.
Purple flooded in, strand by strand, until a dark, blood-tinted mane fell chaotically around his face.
It lengthened — just enough — tugged by the churning aura rising around him.
Belzebuth narrowed his eyes.
— This isn't just overload…
This isn't a simple awakening.
His voice was almost… low.
— What did you play with, little human…?
Adam, behind the shadow mask covering him, felt something vibrate inside his own body.
A resonance.
An echo.
— …That's not… normal…
His words vanished under the roar.
Kael's eyeballs darkened.
The whites disappeared completely, drowned in viscous black like ink poured into his sockets.
The pupils tightened.
The left one turned deep crimson-purple, pulsing like a living ember.
The right one turned gold — cold, sharp, authoritarian.
Two colors.
Two forces.
Two wills.
In the same gaze.
Umbra paled — or whatever the shadow equivalent was.
His edges quivered.
— Gyah… n-no… no no no…
He clutched Veda tighter, despite her wounds, as if holding her could keep her safe from what stood just meters away.
The Replacement swallowed hard.
— This… this isn't a candidate anymore.
He checked something only he could see.
[ Status: Unclassifiable. ]
[ Anomaly: access level insufficient. ]
— How is that 'insufficient'…?
I'm the administrator of this floor.
For the first time, he stepped back.
Kael did not.
He trembled.
Each tremor shifted his bones beneath the skin.
His ribs rearranged like pieces on an internal board.
He laughed again.
A cracked, burning laugh echoing like an inverted sob.
— Hahaha… ha… ha… it… it hurts… so much…
A tear of black Magia fell.
It hit the stone — and the stone smoked.
He went silent instantly.
Then whispered:
— Continue.
The words weren't for Belzebuth.
Or the Replacement.
Or any enemy.
They were spoken inward.
And the voice answered, delighted:
— With pleasure.
His fangs grew again, tearing deeper into his own gums.
His blood wasn't red anymore.
It was dark, thick, stained with red shards and golden gleams.
The pain rose.
Again.
Harder.
He screamed.
— AAAAAAAAAAH—!!
Mid-scream, he broke into laughter.
A laugh and scream overlaying each other — pain and madness intertwined.
Veda started crying again.
— Kael… stop… please…!
Ridiculous.
She knew it.
He wasn't in control of anything.
But she wasn't talking to the monster.
She was talking to the boy buried somewhere inside.
Kiyoshi clenched his teeth, hands trembling.
— Is… is this him…?
Is that really… Kael…?
Gravyor didn't answer.
His gaze stayed fixed on Kael's distorted silhouette.
— That… ain't our Kael, he growled.
Not the one from earlier.
Belzebuth tilted his head slightly, amused again.
— Oh, but it is.
His voice rang clear.
— It is exactly him.
His eyes gleamed with dangerous delight.
— You simply hadn't met this side yet.
The inner voice sharpened, heavier, clearer.
— Look, Kael.
An image unfolded in his mind.
Chains.
Flames.
A throne — empty.
— You're not becoming someone else.
Pain ripped through him.
— You're remembering who you are.
He shook his head violently, black tears flowing.
— I… no… that's… that's wrong…!
— Then why isn't it breaking…?
Why does it hold?
Another bone cracked.
His hip shifted, then locked into place.
His leg trembled — then stood firmer than before.
His aura tightened, condensed, molten and thick.
The Replacement stumbled back again, voice pale:
— That flow… that flow isn't human.
He turned to Belzebuth.
— You… you knew…?
The Infernal Prince smiled faintly.
— I knew he was interesting.
I didn't know he was… this.
Umbra trembled harder.
He stepped back, still clutching the others.
— Gyah… it's… like back there…
He lifted his terrified gaze toward the empty air where Thana should have been.
— I don't want to go back…
Kael bent forward.
His clawed hands dug into the stone like it was soft earth.
A mad silence fell.
No scream.
No laughter.
Just breathing.
Slow.
Deep.
He inhaled as if something massive had just sunk into his lungs.
Then raised his head.
His eyes — pitch black, with a crimson-purple left pupil and a golden right pupil — scanned the platform.
They passed over Veda.
Kiyoshi.
Gravyor.
Umbra.
Then Belzebuth.
Then the Replacement.
A smile carved itself across his face.
Not joy.
Not pure madness.
Something between the two.
A cracked smile.
He spoke.
And this time, everyone heard him.
His voice — but doubled.
Two tones.
Kael's…
and another, deeper one layered beneath.
— …So it's you.
The Replacement felt a shiver crawl down his spine.
— The temporary administrator, huh…
Kael tilted his head.
— You really think… you can stop me from leaving…?
Red warning lines flickered around him — invisible to all but him.
[ Warning: attempted authority override not recognized. ]
[ Warning: access level insufficient. ]
The Replacement blanched.
— H-how can you… see that…?
Belzebuth gave a small, sharp laugh.
— …Magnificent.
Kael turned toward him.
His crimson-purple pupil pulsed.
The golden one narrowed.
He stared without speaking.
Then, inside his head, the other voice whispered:
— Let me play.
Kael began laughing.
Low.
Controlled.
Slower now.
But still cracked.
— Hahaha…
Then suddenly he burst again.
— Ah… ahahah… ah… I can't… I can't take it…
His face twisted, torn between hysterical laughter and sobbing.
— Make it stop… I beg you…!
He spoke aloud.
Then, inside, the answer came:
— You asked for strength.
You asked to save them.
A price had to be paid.
A sob tore out of him.
— I… I don't want to be like you…!
— Too late.
His black-and-red aura snapped inward, clinging to his skin like a second layer — a living armor.
The stone beneath him cracked.
The ground around him split in spiderweb patterns.
Veda gripped Umbra's hand, not daring to look.
— Why… is it so cold…?
Umbra didn't answer.
Because he knew.
It wasn't cold.
It was fear.
The fear of something that had awakened.
Not a demon.
Not a prince.
Not a guide.
An anomaly.
Kael lowered his head slightly.
His purple-black hair fell over his face, hiding half his mismatched eyes.
When he spoke, everything froze.
— Belzebuth.
The Infernal Prince raised a brow.
— Yes…?
A silence.
Then, with both voices layered, Kael said:
— You should never have touched her.
The sentence dropped like a verdict.
And with it, the entire Tutorial understood
that what had awakened here
was never meant to exist.
