The Heroine is My Stepsister, and I'm her Final Boss-Chapter 398 - 396: Be Ours...

A sudden gust hit the cave—hard enough to push Atlas one step back.

The lanterns rattled.

Lara gasped, grabbing onto Aurora.

Eli spread his wings wider, shielding the group.

The storm throbbed like a living thing.

Then—

A voice.

Not spoken.

Not shouted.

Exhaled.

Low, resonant, vibrating through the bone of the mountain itself.

"...Atlas..the prophet..."

Lara’s blood ran cold.

She grabbed Atlas’s arm so tightly her nails dug into his skin.

"H-how does it know your name?"

Atlas didn’t have an answer.

Because he recognized the tone.

Not the voice—but the tone.

A tone he heard only once before.

A battlefield of black fire.

A sky collapsing into itself.

A defeated King burning under his own pride.

The moment Asmodeus died—

No.

Not died.

Changed.

The voice carried the same broken regret.

The same desperate hunger for a fight.

The same quiet disappointment at a world that never went the way it was meant to.

Atlas’s throat tightened.

"...Seraph?" he whispered.

But the Guide jolted violently inside his mind.

{{{{ NOT SERAPH. }}}

{{{{ Another version. Another timeline. A piece of a battle that never happened. }}}}

{{{{ The Fourth Layer is pulling ghosts from undone futures. }}}}

Atlas’s blood turned to ice.

A second voice echoed from the storm—rougher, harsher.

"...Prophet."

This one Atlas KNEW.

Even Michael recognized it, his whole face draining of color.

"That—that sounds like—"

"Asmodeus," Atlas finished quietly.

But that made no sense.

Asmodeus was Seraph.

The High Elder.

Changed by time.

But this voice was younger.

Sharper.

Hotter.

A version before the Fourth Layer warped him.

Eli’s sword trembled. Like the time of war.

"Are we dealing with... two of them now?"

The Guide answered with a long, suffocating silence.

Then:

{{{{ This Layer does not obey linear existence. }}}}

{{{{ Past, future, corpse, memory... }}}}

{{{{ It treats them all the same. }}}}

Atlas felt a cold sweat down his spine.

"So that thing in the storm... could be a version of Asmodeus that shouldn’t exist?"

{{{{ Exactly. }}}}

Another wingbeat—this one so strong it blew snow into the cave like a tidal wave.

Aurora staggered back coughing.

Lara shielded her eyes.

Michael fell to one knee.

But Atlas stood his ground.

His eyes locked on the swirling curtain of white.

The storm parted again.

This time the figure stepped closer.

And it was worse than he imagined.

Tall as a mountain-giant,

muscles carved like obsidian,

horns cracked and splintered,

wings torn in places yet regenerating in slow pulses of golden light.

And its face—

Its face was split between two states.

Half Asmodeus as Atlas once knew him—

sharp-eyed, proud, furious.

Half Seraph—

older, wiser, scarred by time.

A hybrid of timelines.

Two impossibilities merged into one.

A creature that should not exist anywhere.

Especially not here.

Michael whispered a panicked prayer.

"... Atlas, we need to run—"

"Run where?" Eli snapped.

"He can fly. We cannot."

Aurora hissed, "Shut up—look."

Because the creature was kneeling.

The mountain trembled as the titan lowered itself onto one knee in the snow, its head bowed toward the cave.

The snow around it melted—

not from heat,

but from sheer spiritual pressure.

The being raised its head.

Its mismatched eyes locked onto Atlas.

One eye Asmodeus-red.

One eye Seraph-blue.

When it spoke, both voices overlapped—

young and ancient, furious and calm, demon and elder.

"Atlas," the hybrid intoned,

"the prophet I never killed."

A slow shiver curled up Atlas’s spine.

He stepped forward despite Lara’s grip.

"Why are you here?" Atlas asked quietly.

The being’s wings flexed, scattering snow like shards of light.

"Because your arrival disturbed the Layer," it said.

"You pulled on threads that were never meant to be touched."

"What threads?"

Its two voices merged into a low, vibrating answer—

"Fate...."

Atlas’s jaw clenched.

Of all things, he hated that word.

The being continued:

"You carry the Guide.

You carry Lilith’s blood.

You carry the weight of false prophecy...

...that is becoming true."

Aurora whispered, "It knows everything..."

The being continued, louder:

"And you carry something else."

Atlas stiffened.

The Guide inside him recoiled hard.

{{{{ DO NOT LET IT SPEAK. }}}}

{{{{ IF IT TELLS THEM, EVERYTHING CHANGES. WE CAN’T KNOW THE COMING FUTURE...}}}}

But the hybrid leaned forward, its breath fogging the air, eyes blazing—

"You carry the possibility to rewrite the Fourth Layer."

Silence.

Not the quiet kind.

The suffocating kind—heavy, total, crushing every breath.

Eli stared at Atlas.

Lara’s grip tightened.

Aurora’s brows furrowed.

Only Michael reacted out loud.

"...Rewrite it?" he whispered.

"Atlas can rewrite an entire Layer of Hell?"

The hybrid’s answer shook the snow loose from the cliffs.

"Yes."

Atlas felt his pulse slam against his ribs.

"That’s impossible... I’m just one being..." he muttered.

The being smiled—

a broken, haunting smile.

"Impossible things survive here.

I am one of them....and I know you are one of them..."

Its wings expanded—

massive, filling the storm, thicker than thunderclouds.

Then it pointed one clawed finger at Atlas.

"Seraph..the old version of me, sent you to rest.

He did not tell you why."

Atlas swallowed.

"Why?"

The voice that answered was the voice of a demon king dying—

and an elder born from that death.

"Because when the Empress arrives...

even Seraph cannot control what happens next...the last Empress...she doesn’t see you as the same way Lilith does, not the same way as the other one too...."

Lara’s breath hitched.

Aurora’s blade trembled.

The storm rumbled like distant laughter or distant doom—hard to tell which.

Atlas stepped forward, heart pounding. This...this was not an attack, this was a warning, a warning he needed to take heed off...

"...What does this Empress want with me?"

The hybrid lowered its head in something like pity.

"She wants what everyone wants from you now."

"And what’s that?"

The creature leaned forward, eyes burning with two conflicting eternities.

"To see whether you become a savior..."

"...or the beginning of another war...she saw the unmaking of all the first , second and mostly third layer of hell...and she saw it closely..."

A gust of wind blasted the cave entrance—

so violent that Lara staggered back, Aurora shielded her, Michael fell, Eli braced his wings.

Atlas alone stayed standing, staring directly at the impossible being.

For a moment, he felt the world shrink.

The snowflakes slowed.

The wind dimmed.

The Guide inside him went silent.

And in that hanging second—

Atlas understood the truth.

The Fourth Layer wasn’t just a place.

A crucible.

A twisting of time, fate, memory, and identity—

meant to see what broke first:

The world.

Or him.

The hybrid’s wings drew inward.

Its body dissolved—not into mist, but into white fire and black feathers, consumed by its own paradox.

The storm swallowed it whole.

Gone.

Not dead.

Not alive.

Simply...

unmade.

The silence that followed felt like a bruise pressed too hard.

Lara whispered, trembling:

"Atlas... what was that thing?"

Atlas stared into the storm, feeling the weight of a destiny he never asked for pressing against his skull.

His breath drifted out as fog.

Only three words left his mouth.

"A warning."

The Guide finally whispered again—

soft, shaken, afraid in a way Atlas had never heard before.

{{{{ Haaa....asmodeus, he saves and he warns, he’s trying to change the future....and the Empress, she is already on her way. }}}}

Michael paced nervously, his boots crunching softly on the frost-covered stone.

Aurora leaned against a carved pillar, eyes narrowed, fingers twitching like she expected a fight at any second.

Lara clung to Atlas’s sleeve without realizing it, her breath small and tight.

Eli knelt at the edge of the cave, running his palm across the snow.

"It’s warm," he muttered.

And it was—strangely warm, despite the blizzard outside.

Atlas’s pulse quickened.

The Fourth Layer didn’t obey natural laws.

Time, temperature, space—none of it was fixed.

Everything bent toward something...

or someone.

A faint hum spread through the cavern.

The walls shimmered gently, as though light was leaking through cracks in reality.

Michael froze mid-step.

"Is she... coming?"

Aurora pushed off the pillar.

"She better not be hostile. We can’t—"

Lara cut her off, whispering,

"Do you... feel that?"

Atlas did.

Something was approaching—

not a person,

not a presence,

but a concept.

The air thickened, vibrating like a plucked string.

Snowflakes stopped mid-fall at the entrance, suspended in the air like glass beads.

The light shifted, turning soft and rose-colored, then violet, then a deep, ancient gold.

Aurora swallowed hard.

"That’s... not normal. Was this the warning, Asmodeus was giving..."

Michael dropped to his knees in a heartbeat.

"It’s her. The Empress. The one Seraph mentioned."

Atlas felt his heart hammer.

The Guide inside him whispered sharply—like he was breaking.

{{{{ Brace. Brace. SHE bends layers. }}}}

The walls pulsed again—

and then broke.

Light crawled across the stone like veins awakening.

Symbols he had never seen before ignited along the ceiling.

Every breath tasted like charged air.

Then time stuttered.

Atlas blinked—

and the world repeated itself.

Lara’s hair flicked behind her—

then flicked again the exact same way.

Aurora exhaled—

then exhaled again, the same sound in the same rhythm.

A ripple of dread slid down Atlas’s spine.

"Time loop," Eli whispered.

"She’s forcing a time loop."

Atlas stepped forward instinctively.

He didn’t know why—

only that something in the air was pulling him.

And then...

She arrived.

Not with footsteps.

Not with a voice.

Not with a figure.

She arrived as a shift.

The snow outside melted instantly, flowers blooming in its wake—

violet petals blooming and dying all within a second,

their life spans compressed to a heartbeat.

A silhouette formed in the light—

a woman’s outline.

Tall.

Regal.

Terrifying in her stillness.

Her presence pressed against Atlas’s mind,

not like a voice

but like a truth he had always known.

The Empress stepped through the shimmering light.

She didn’t walk—

she glided.

Reality adjusted itself around her;

the floor rose to meet her feet,

the stone rearranged itself to her liking.

Her dress was woven from shifting layers of starlight and obsidian threads.

A crown hovered just above her head—

not touching her,

as if the concept of "weight" refused to apply to her.

When she exhaled,

snowflakes within ten meters sublimated into golden dust.

Michael bowed so deeply his forehead hit the stone.

Aurora lowered her sword—carefully.

Eli stared like someone staring into the sun. 𝙛𝓻𝒆𝒆𝒘𝙚𝓫𝙣𝙤𝒗𝙚𝓵.𝙘𝙤𝙢

Lara hid behind Atlas, trembling.

Only Atlas stood fully upright.

The Empress smiled.

Not kindly.

Not cruelly.

Like someone watching an interesting gamble unfold.

"So," she murmured,

her voice echoing through the stone in several tones at once,

"the False Prophet arrives. Carried here by Essence of Asmodeus, no less."

Atlas’s chest tightened.

False Prophet.

She said it without contempt—

but with a certainty that burned.

He forced himself to speak.

"You came for me."

"Of course," she said, stepping closer.

"Your arrival rippled through every fold of this layer.

Even the Frozen Gates began to thaw.

Seraph has not moved so urgently in an age."

Her eyes—gold with a rim of violet—drifted across the group.

She stopped on Lara.

Lara froze.

The Empress reached out a single finger

and touched Lara’s forehead.

Light sparked—

not bright,

but sharp.

Like a needle of pure intent.

Lara gasped, stumbling back.

A faint symbol glowed on her skin—

a sigil Atlas didn’t recognize.

He caught her before she fell.

"What did you do to her?" he demanded.

The Empress tilted her head.

"Marked her."

"For what?"

"A reminder," she murmured.

"For you. For me. For what you will become.....she is born from lady fate, and lady fate doesn’t like us, like you....you should know by that now... "

The Guide inside Atlas hissed—

{{{{ She SEES you. Not your body—YOUR SELF. }}}}

’He’s breaking, panicking... more and more since we arrived here...’ atlas thought.

Before Atlas could ask more,

the world snapped.

Like glass cracking.

A rift opened behind the Empress,

a long vertical tear that glowed white-hot.

Shadows poured out of it—

no shape, no face,

just raw fear.

And within the rift—

Atlas saw himself.

Dead.

His own corpse,

broken at the base of a throne he didn’t recognize,

surrounded by crows.

Aurora swore violently.

Lara clutched Atlas’s arm so hard her nails dug in.

The Empress didn’t turn.

She simply said:

"The Fourth Layer shows what is most likely.

Not what must be."

Atlas forced air into his lungs.

"Why are you showing me this?"

"I didn’t."

She looked him in the eyes.

"You triggered it... yourself...."

The rift closed instantly.

Silence clung to them

like frost.

The Empress circled Atlas slowly.

Every step shifted the gravity in the room;

his heartbeat changed pace with her movements.

"You carry two destinies," she said softly.

"One written by the One Below All...

and one written by One Above All...

But it seems, only I see it, and my sisters don’t..."

Her gaze sharpened.

"But only....one survives..."

Atlas felt the Guide coil inside him like a trapped animal.

{{{{ Don’t let her DEFINE you.... }}}}

The Empress raised a hand—

and time froze.

Everyone except Atlas held still,

like statues in a storm.

Even the falling petals stopped mid-air.

Only she and Atlas could move.

She leaned in,

her voice dropping to a whisper that shook the cavern.

"Seraph... Asmodeus.. didn’t tell you the truth," she said.

"He didn’t change his name...

He escaped it."

Atlas’s breath hitched.

"Escaped what?"

Her smile was thin as a blade.

"The thing that tried to claim him.

The thing that now... is studying you."

The walls trembled.

A pulse of ancient, buried dread rippled through the cave.

Atlas whispered,

"...What is it?"

She stepped closer,

her forehead nearly touching his.

"You call it the Guide."

Atlas froze.

His heart stopped.

His lungs forgot how to breathe.

The Guide inside him went silent—

not hiding,

not recoiling—

but like something holding its breath.

The Empress’s gaze softened,

as though she saw the exact moment Atlas understood something

he had been trying not to believe.

"Tell me, little prophet," she whispered.

"Has it ever once told you the truth of what it is?"

Atlas swallowed.

The silence in his mind was suffocating.

She leaned back slightly, examining him.

"Good. That fear in your eyes?

That means you’re starting to awaken...the version of Asmodeus which you defeated in the third layer wasn’t lying...."

Atlas clenched his fists.

"What do you want from me?"

"Simple," she said.

"Be owned by us three sisters...."
