The Heroine is My Stepsister, and I'm her Final Boss-Chapter 426 - 424: WHEN FAITH BECAME WEIGHT

The world held its breath.

Not in silence—never silence—but in tension, like a muscle drawn so tight it forgot how to relax.

Atlas stood amid ruin and lightning, blood dripping from his chin, LAW flickering weakly through his veins, Thor's hand still hovering inches from his throat. Cities burned in the distance. The sky churned like a wounded animal. Some fallen Angels lay broken across shattered stone. Humans fled, screamed, prayed, ran—

And then something changed.

Not above.

Below.

It began with a single human.

A woman crouched behind an overturned cart, rain and ash streaking her face. She had been running. She had been screaming. She had been certain she was about to die. Her eyes were wide, empty with panic—until she looked up.

She saw Atlas standing.

Bleeding.

Unbowed.

And for the first time since the storm began, she stopped running.

A man followed her gaze. Then another. A child tugged on her father's sleeve and pointed. Soldiers halted mid-retreat. Civilians stumbled to a stop in the streets, turning as one toward the impossible figure standing against a god.

Someone shouted his name. One of the fallen angel who were sent to survey.

Not in prayer.

In defiance.

And the world answered.

Atlas felt it before he saw it.

A pressure—not crushing, not painful—but heavy. Like hands pressing against his back, steadying him. Like weight settling into his bones, grounding him. His Demon God Heart stuttered once—

Then thundered.

A pulse rolled outward from his chest, invisible but absolute. The air vibrated. Lightning hesitated mid-arc. LAW screamed warnings too late.

Blue light erupted in front of Atlas's eyes.

Not one notification.

Many.

Too many.

They stacked, layered, overlapping faster than thought.

[Sufficient Faith Points Accumulated]

[Faith Detected: Mass Recognition]

[Status Adjustment Initiated]

The world seemed to dim around him as the text burned white-hot.

STR +500

STR +1000

STR +2500

STR +5000

His muscles convulsed violently. Bones groaned. Atlas dropped to one knee—not in submission, but because the ground cracked beneath the sudden increase in mass his body carried.

MANA CAPACITY +300%

MANA REGENERATION ×10

LAW STABILITY +200%

LAW EFFICIENCY +350%

His vision went white.

Not gold.

Not divine.

White.

Pure. Violent. Human.

Light tore through his veins, replacing pain with heat, exhaustion with clarity. His shattered ribs snapped back into place in an instant. Torn muscle rewove itself. Blood evaporated from his skin in hissing steam.

Thor felt it.

He staggered back half a step, lightning snapping erratically from his body.

"What did you do?" Thor demanded, eyes narrowing.

Atlas rose slowly.

Every movement carried weight now. Not metaphorical—literal. The ground cracked under his boots as if reality itself struggled to support him. His skin glowed faintly, not radiant, but burning, like a star forced into human shape.

"I didn't do anything," Atlas said quietly.

His voice carried.

Not magically.

Personally.

"They did."

Across the battlefield, humans began to shout.

Cheers broke out—not triumphant, not joyful, but desperate and fierce. Cries of disbelief. Of hope. Of rage turned outward instead of inward.

Angels felt it ripple through their wings like fire. Demons froze mid-fight, instincts screaming that something fundamental had shifted. Ouserous clutched his chest, breath hitching as something unfamiliar twisted in his gut.

Fear.

Thor's storm sputtered.

The clouds above recoiled as if pushed back by an unseen force.

Faith had mass.

And it was pressing down on him.

Atlas moved.

He didn't teleport.

He stepped.

The world failed to keep up.

The space between Atlas and Thor collapsed as if embarrassed to exist, air imploding inward with a shriek like a dying star. Atlas's fist connected with Thor's jaw—and for an instant, there was no sound at all, just a violent absence where noise should have been.

Then reality gave up trying to pretend this was normal.

The impact did not knock Thor back.

It deleted his position.

Boooommm!

Reality cracked....Again.

Thor vanished in a concussive rupture of displaced existence, his body hurled upward through layers of sky like a shell fired by a god-killer. The clouds didn't scatter—they were annihilated, erased into vapor and static as Thor tore through them, lightning detonating uselessly behind him, chasing a body that was already gone.

Atlas was already moving.

He didn't chase.

He arrived.

The air screamed as Atlas broke past the sound barrier without acceleration, without resistance, his passage leaving behind a vacuum that collapsed in thunderous shockwaves. The pressure tore buildings apart below, windows shattering miles away as the sky itself rippled in protest.

They broke through the veil of the Lower Heaven like a meteor strike.

Golden clouds ignited on contact, divine atmosphere combusting as Thor slammed into a floating city of marble and light. Towers sheared in half. Bridges shattered into radiant debris. Statues of forgotten saints exploded into dust as Thor plowed through them, his body carving a trench through paradise itself.

Minor demi gods scattered in blind panic.

Some screamed.

Some prayed.

Some froze, wings locking in terror as the god of thunder destroyed their refuge simply by existing within it.

Atlas caught up mid-flight.

He didn't slow.

He struck.

Booooooommmm!

Reality cracked once more.

His fist crashed into Thor's spine with a sound like continents colliding, compressing divine muscle and bone inward. The force folded Thor's body around the blow and launched him downward, ripping a vertical wound through Heaven's underside.

The sky tore open.

Light inverted into shadow.

They fell.

Through the broken floor of Heaven and into screaming heat.

Hell welcomed them with violence.

Thor smashed through the ceiling of the second layer like a divine execution, chains snapping as his body tore through ancient restraints thicker than castles.

Frozen titanic corpses embedded into the architecture cracked and splintered, their screams echoing through eternity as the impact woke punishments that had been dormant for ages.

The air here tasted of frost and old sins.

Gravity howled in agony.

Atlas grabbed Thor by the hair mid-fall, fingers digging into god-flesh hardened by eons of war, and yanked him sideways. LAW flared instinctively—not to command, but to anchor—forcing the strike to remain coherent across realms that wanted nothing more than to tear them apart.

Atlas drove his knee into Thor's face.

The shockwave flattened demon legions three miles away.

Ice mountains imploded. Hell's architecture warped inward, bells tolling as ancient wardings failed all at once. The impact sent cracks racing through the layer itself, entire regions destabilizing as punishment systems overloaded from collateral damage.

Thor roared—not in pain, but fury.

He twisted, lightning erupting point-blank, thunder detonating against Atlas's chest. The blast hurled them apart, smashing them through collapsing hell-geometry, before both were violently expelled upward—

—back into the mortal sky.

They burst through the atmosphere like artillery fire.

Thor hit first.

His body slammed into the earth hard enough to carve a canyon in a single instant, bedrock liquefying on impact, shockwaves racing outward until distant mountains cracked in sympathy. Fire and debris erupted skyward, a pillar of destruction marking where a god had fallen.

A heartbeat later—

Atlas landed.

Not crashing.

Landing.

The ground shattered beneath his boots, fractures spiderwebbing outward as his weight pressed reality into submission. Dust and flame rolled past him in waves, his silhouette standing unmoved at the center of the devastation.

He straightened slowly.

Above him, the sky groaned.

Below him, the world trembled.

And somewhere deep beneath it all, something ancient stirred—aware now that gods were being treated like weapons, and weapons like obstacles.

Thor rose snarling, blood streaming down his face, lightning flaring wildly around him. "You think belief makes you my equal?"

He hurled Mjölnir.

The hammer descended like a falling star, lightning compressing into a column that vaporized everything in its path.

Atlas stepped into it.

He reached out.

And caught it.

Mjölnir screamed.

Lightning poured into Atlas relentlessly, burning, tearing, rewriting him cell by cell. His skin charred black. Bones glowed through muscle. LAW buckled under the strain.

Humans screamed.

Angels cried out.

Ouserous shouted something incoherent.

Atlas gritted his teeth.

Faith burned.

Not consumed.

Burned.

His body held.

Thor stared, eyes wide with disbelief. "Impossible," he whispered. "You're mortal."

Atlas looked up, eyes blazing white.

"Not anymore."

He tightened his grip.

CRACK.

Mjölnir fractured.

The sound echoed across every realm.

The hammer shattered into fragments of screaming runes and broken legend, lightning detonating outward as Thor was thrown back by the destruction of his own weapon.

The ocean beyond the battlefield pulled away violently.

The ground trembled.

A roar echoed from the Dark Continent.

Yormungander awoke, feeling her own blood boil, resonating with something...or someone.

The World Serpent rose, coils breaking the sea's surface, eyes like ancient suns locking onto Atlas. It did not attack. It did not threaten.

It recognized.

It roared—not in challenge, but approval.

The storm bent away from Atlas instinctively.

Thor pushed himself upright, rage giving way to something closer to panic. "All Father!" he roared. "LOOK AT ME!"

The sky answered with silence.

Thor charged, power ripping free of restraint, each step erasing stone, air, memory alike. He swung his shattered arm, lightning forming a blade of pure destruction.

Atlas met him head-on.

Fist to fist.

Impact shook the planet.

They traded blows that tore holes through the sky, each strike rewriting gravity, shattering time for fractions of a second. Atlas felt his Faith Points draining rapidly, every movement costing him something precious—but he didn't slow.

Thor did.

Desperation crept into his movements. Sloppiness. Fear.

Atlas saw it.

He stepped inside Thor's guard and drove a punch into his chest.

Thor flew backward, crashing through a mountain and skidding to a stop miles away, smoking crater marking his path.

Atlas approached slowly.

Thor struggled to rise.

Ouserous appeared between them, landing hard, arms spread wide.

"Wait!" Ouserous shouted, eyes wild. "Please—don't! He's my father!"

Atlas stopped.

His fist trembled.

For a heartbeat, the world held its breath again.

Thor snarled. "Move...."

Atlas looked down at Ouserous.

Then past him.

At the burning cities.

The dead fallen angels.

The terrified humans still watching.

Atlas's eyes softened.

Then hardened.

"No," he said.

He stepped around Ouserous.

Thor screamed in rage and lunged—

{THE END}

Atlas's final punch landed.

It didn't kill Thor.

It didn't forgive him.

It ended him.

The god of thunder slammed into the earth, power ripping away violently, lightning dissipating into harmless sparks. When the dust settled, Thor lay broken, bleeding, mortal.

The storm cleared.

The sky opened.

Atlas dropped to one knee, light fading, body finally acknowledging the cost. Faith drained to embers. Pain returned all at once.

Humans stared.

No one cheered.

They didn't need to.

The world had seen enough. They had seen enough.

A mortal killing a GOD.
