The Heroine is My Stepsister, and I'm her Final Boss-Chapter 397 - 395: Edge of Time
The air in the Fourth Layer tasted different.
Sharper.
Thinner.
As if every breath carried the metallic sting of time itself bending around them.
Atlas felt the shift the moment the Elders’ arena vanished and the world trembled—
the moment a presence overshadowed all the others.
A presence older than blood.
Older than Hell.
Older than the Guide whispering inside his bones.
A presence that stepped forward now, parting the Elders like the tide.
Seraph.
But the moment Atlas saw him—
truly saw him—
a cold ripple shivered down his spine.
Because the aura hitting him was impossible to mistake.
Wild.
Ruthless.
Burning with the same violent frequency that once shook the Underworld during their fight.
The same frequency as—
Asmodeus.
Just more fractured.
More ancient.
Like a storm left raging long after the world that birthed it died.
The high elder’s steps echoed across the living floor of the arena.
Every footfall felt like a pulse from a creature far too large to see.
His height matched Asmodeus’s exactly.
His shoulders.
His silhouette.
Even the faint tilt of his jaw.
But his skin held more scars now—
scars carved by centuries Atlas could not comprehend.
When Seraph finally spoke, his voice carried a weight that made the Elders bow their heads ever so slightly—
a sign none of them gave easily.
"So," Seraph said, dark amusement curling beneath each word,
"the fake prophet truly managed to defeat Asmodeus."
A jolt ran through Atlas’s chest.
There.
There it was.
The confirmation.
His instinct sharpened.
His thoughts clicked together like puzzle pieces snapping home.
He knew it.
He knew that aura anywhere.
But still—
seeing this man, this... elder, wearing that presence like an echo...
Atlas couldn’t stop himself.
"Are you related?" he asked quietly.
Seraph smiled.
It wasn’t warm.
It wasn’t cold.
It was a smile built from memories older than language.
"I do not remember you," Seraph said.
"Not as I am now."
Then he paused.
The crowd leaned in unconsciously—
every demon, every fallen, every beastfolk.
Even the air stilled, as if waiting for the end of a story torn from myth.
Seraph touched his own chest,
then his temple,
then the scars across his ribs.
"I am Asmodeus...or I was...," he said.
"Long ago. Before time curved. Before the Fourth Layer swallowed me."
Lara stiffened beside Atlas.
Aurora’s hand moved toward her blade.
Michael’s breath hitched audibly.
Even Eli—who almost never reacted—took a slow step back.
Atlas’s pulse hammered so hard he felt it in his fingertips.
Asmodeus.
The King he fought.
The one whose face he scarred.
And now he was... this.
A high elder.
A being beyond demon kings.
A creature shaped by a dimension where time itself twisted like a serpent eating its tail.
Seraph spread his arms slightly.
"Time works differently here," he said.
"Nothing in the Fourth Layer moves the way your Third-Dimensional world does."
The shadows behind him rippled like water.
"The Fourth Layer touches only the edge of the Fourth Dimension.
It is enough to twist age... memory... identity."
Atlas’s throat tightened.
Something inside him—something small, human—
felt suddenly very, very out of place.
Seraph’s gaze sharpened.
"So tell me, fake prophet," he said, stepping closer,
"are you prepared for that?"
Atlas SHOULD have hesitated.
He SHOULD have stepped back, or questioned, or doubted.
But instead—
He studied the scars on Seraph’s face.
Not fresh scars.
Ancient ones.
Battle-worn, rugged, carved into his flesh so deeply they almost glowed with the same brutal energy as the day Atlas made them.
Atlas’s lips curved into a slow, dangerous smirk.
"I see the marks I left on you," he said softly.
"You’re powerful enough now to erase them.
Why haven’t you?"
Seraph inhaled—
sharp and cold, like someone remembering a blade in the dark.
Something flickered across his face.
Something raw.
Almost human.
He looked away for a moment,
up toward a sky that pulsed like a heartbeat.
When he exhaled,
it sounded like a man forcing his memories back into the box they escaped from.
"You have not changed," Seraph murmured.
"And I hoped you never did..."
A quiet shiver crept through the Elders.
They had never heard the high elder speak like that.
Seraph turned, raising a staff that materialized from shadow—
black wood veined with silver fractures, humming with power that tasted like lightning.
He slammed it into the floor.
The entire arena shook.
"THIS," Seraph thundered,
"is the prophet we have awaited!"
His voice cracked the air like a whip.
The ground glowed beneath Atlas’s feet.
"No crown, no council, no throne in Hell or Heaven can deny it!"
The arena erupted.
The Elder who had guided Atlas stepped forward, bowing deeply toward Seraph.
"Thank you, High Elder," he said, relief spilling through his voice.
Then—
The world shattered.
A scream of wings tore through the air—
thousands of them.
Crows—
black, violet, silver—
materialized like a living storm around them.
The ground ripped open under their feet.
The arena dissolved into smoke.
The cheers cut off mid-roar, swallowed by darkness.
Michael grabbed Raphael’s arm.
Lara pulled Aurora close.
Eli shielded them with his wings.
Atlas felt the Guide inside him surge—
{{{{ MOVE OR BE CONSUMED. }}}}
But there was nowhere to move.
The crows spiraled inward,
a vortex of feathers and ancient magic,
swallowing them whole.
The world blinked.
And suddenly—
Silence.
A wind howled—
cold enough to slice skin.
Thin enough to sting the lungs.
Atlas gasped, breath turning into frost.
They were standing on a mountaintop.
Snow fell in slow spirals around them,
each flake glowing faintly with an inner blue light.
It wasn’t normal snow.
It felt heavier,
older,
like the dust of forgotten ages instead of frozen water.
The sky above them swirled in impossible colors—
violet storms colliding with silver lightning.
Their footprints crunched gently as they approached the cave ahead—
a structure carved into the mountainside as if the mountain itself had hollowed out space for them.
Inside—
Warmth.
Soft, flickering warmth.
The cave opened into a chamber too smooth to be natural,
lined with stone that glowed faintly with crimson runes.
Luxurious furs covered the ground.
Lanterns hung from icicle-like crystal ribs overhead.
A table stood in the center, formed from black obsidian shaped like flowing water.
The place felt... prepared.
Not rushed.
Not accidental.
Waiting.
Seraph stood at the far end of the chamber.
Snow melted instantly around his feet, steaming as he walked.
His staff tapped once,
twice,
three times—
and the air tightened like a drawn bowstring.
"Rest here," Seraph said, his voice quieter now.
Almost gentle.
"Your arrival has been anticipated for... a very long time."
Atlas’s stomach twisted.
A strange sensation stirred in his chest—
a heaviness that was not fear,
not relief,
and not quite dread.
Something in-between.
Seraph continued:
"I have waited for you with enough patience to erode mountains."
"And I will return when the time is right."
Atlas opened his mouth to ask what time meant to someone whose memory was older than dates—
but Seraph wasn’t looking at him anymore.
He was looking beyond him.
Through him.
Into something Atlas couldn’t perceive.
"Your presence," Seraph said slowly,
"and the empress’s decision to descend personally...
has already spread through the Fourth Layer."
Lara stiffened.
Aurora grabbed Atlas’s sleeve unconsciously.
Michael mouthed the word Empress? in dawning terror.
Seraph gave a small, almost pitying smile.
"You have stirred the nest."
"And the Fourth Layer always responds."
Black crows rose again—
quiet this time,
like shadows lifting from the ground.
They circled Seraph slowly.
Lovingly.
As if greeting a king.
And as they swallowed him from the bottom up,
he spoke one last time—
his voice echoing off the cave walls like a prophecy carved into stone.
"Rest while you can, prophet."
"The Fourth Layer remembers its debts."
"And its monsters."
Then he was gone.
The cave fell silent aside from the soft whisper of falling snow outside.
Atlas’s breath fogged the air.
Lara edged closer to him, her voice trembling.
"Atlas... what do we do now?"
A crack ran through the fire in the hearth—
loud, sharp, like a warning.
The Guide dragged a whisper across Atlas’s mind,
cold and frantic.
{{{{ He was Asmodeus and yet... not. }}}}
{{{{ Time is wrong here. The rules you know do not apply. }}}}
Another whisper, darker—
{{{{ And something else is coming. }}}}
Atlas stared at the empty space where Seraph vanished.
His heartbeat echoed in his ears—
steady,
heavy,
like a drum announcing the next act of a tragedy.
The cave felt smaller now.
Tighter.
Like the mountain held its breath.
A single snowflake drifted inside,
landing on his palm.
It did not melt.
It burned.
Atlas closed his fist around it.
A lingering thought spread through him—
quiet,
terrifying,
inevitable.
If time twisted Asmodeus into Seraph...
What would it twist Atlas into?
The wind outside howled again,
carrying with it the faintest sound—
wings.
Not crows.
Too large.
Too slow.
Too heavy.
Something that moved the air like a continent shifting its weight.
Atlas stepped toward the cave entrance, slow and cautious, each movement deliberate.
Snow brushed against his skin—cold, but not natural.
Each snowflake hummed with faint spiritual vibration, like fragments of a song sung by a dead god.
Behind him, Lara whispered, "A-Atlas...?"
Aurora’s hand tightened on her blade.
Eli expanded one wing slightly, a protective reflex he didn’t even seem aware of.
But it was the Guide inside Atlas who reacted the strongest.
{{{{ STAY BACK. Don’t step into the open. }}}}
His voice struck like a hammer—cold, sharp, bordering on panic.
Atlas froze mid-step.
The Guide rarely used that tone.
In all their battles together—Dreaming gods, demon kings, fallen legions—the Guide had never sounded like this.
{{{{ Something is wrong with this place. We should not be seen yet. }}}}
Atlas felt his heart thud once, hard enough to hurt.
"What is it?" he murmured under his breath.
A ripple of static crawled across his spine as the Guide answered:
{{{{ Something that should not move... is moving. Something that should not breathe... is breathing. }}}}
Another slow wingbeat rolled across the mountain—
deep enough to vibrate the stone beneath their feet.
This time, even Michael felt it.
He clutched his book to his chest.
"Th-that’s not a demon, is it...?"
Eli’s voice lowered.
"...No demon has wings that size."
Atlas stared outward.
The snowstorm thinned for a moment—
a slit in the white curtain.
Enough to reveal a silhouette.
A horned head.
A massive humanoid shape.
Two colossal wings—black feathered at the base, but shimmering gold at the edges where light hit them.
A creature carved from contradiction.
Neither fully angel nor demon.
Neither living nor dead.
The storm swallowed it again.
Atlas felt his pulse hammer in his throat.
"What the hell is that?"
The Guide’s whisper came sharp, like broken glass grinding together.
{{{{ A mistake. }}}}
{{{{ A remnant. }}}}
{{{{ A being the Fourth Layer never meant to keep alive. }}}}
The words chilled him.
But the Guide wasn’t finished.
{{{{ When Seraph said time bends here... he was not warning you enough. }}}}
{{{{ Things that die... continue moving. }}}
{{{{ Things that should sleep... remain awake. }}}
{{{{ And some who should never meet—meet. }}}}
