Screen 1 – Muzan in Asakusa
Asakusa glows with bright lights and laughter…
but to Tanjiro, the night tastes of blood.
Papyrus spins in circles, amazed.
"LOOK AT ALL THESE BEAUTIFUL BUILDINGS! THEY ARE ALMOST AS GRAND AS ME!"
Sans chews a steamed bun.
"Place is lively… guess someone missed the memo that monsters roam around."
Tanjiro tries to smile—
Then the scent hits him.
Metal. Rot.
Muzan.
His body freezes like ice.
Sans's head turns sharply. His easy smile vanishes.
"Kid…?"
Tanjiro whispers a single word, trembling.
"…Muzan."
Then he bolts.
Papyrus shouts after him, "TANJIRO! WAIT! I DO NOT ENJOY CARDIO!!"
Sans teleports forward, blue light flickering like a heartbeat.

The Encounter (Dark Version)
Tanjiro stops dead.
Muzan stands before him—
White suit immaculate, not a single wrinkle.
Eyes cold enough to freeze bone.
A child clings to his arm, unaware she's holding onto a monster wearing human skin.
Papyrus stumbles beside Tanjiro.
"Who's the—"
He stops, shivering.
Even Papyrus feels the killing intent bleeding off Muzan like fog.
Sans's eye flares the faintest blue.
"…That smell. That pressure. You're not just a monster. You're something else."
Tanjiro raises his sword, voice breaking with hate and fear.
"You… killed my family!"
The crowd laughs nervously, thinking it's theater.
Muzan gives a perfect, harmless smile.
"I am a normal human."
Then—
He casually flicks his finger across a man's neck.
The man convulses…
Skin bubbling…
Bones cracking…
Then he howls and tears into a nearby woman.
Screams explode across the street.
Papyrus jumps back.
"THIS IS NOT NORMAL HUMAN BEHAVIOR!!"
Sans steps forward, his killing aura rising like a silent storm.
"You're not human. Not even close."
Muzan stares at Sans and Papyrus like rare insects.
"Your souls… are strange. Not human. Not demon. Something twisted… malformed."
Sans's smile fades into a single deadly line.
"Try me."
The air becomes heavy—
Crushing—
Suffocating—
Muzan's killing intent feels like knives pressing into skin.
Tanjiro chokes on the pressure.
"I'll kill you… I swear… I'll kill you!"
Muzan turns away like Tanjiro is a gnat.
"You may try."
Sans appears in front of him in a blink—
Silent.
Serious.
"Touch my kid, and you'll regret existing."
For the first time, Muzan pauses.
Papyrus panics.
"SANS, THIS SEEMS LIKE A TERRIBLE IDEA!"
Muzan flicks his hand.
A wave of demonic pressure explodes outward—like a shockwave of hatred.
Sans blocks it, bones cracking under the force, blue light flaring violently.
Tanjiro grabs him.
"Sans, stop! Civilians—!"
Sans growls but backs off.
Not because he fears Muzan—
but because Tanjiro asked.
Muzan melts into the crowd, vanishing like a nightmare dissolving at dawn.
---
Aftermath
The screams fade.
The broken, spasming demonized man is dragged away.
Tanjiro collapses to his knees, shaking.
Papyrus kneels beside him.
"WE SHALL FACE HIM AGAIN… AND NEXT TIME WE WILL NOT LET HIM ESCAPE."
Sans stares at the empty street where Muzan stood.
"…that thing wasn't just strong. He was wrong. Like reality bends for him."
Tanjiro wipes his eyes, voice raw with pain and fury.
"I'll hunt him down… even if it kills me."
The three stand together in the broken peace of the ruined street.
---
Screen 2 – Lady Tamayo & Yushiro (Dark Version)
Asakusa's chaos fades into distant cries.
Tanjiro sits in an alley, trembling with the memory of Muzan's presence.
Papyrus gently pats his back.
"THERE, THERE. YOU ARE STILL ALIVE. AND THAT IS A GOOD START!"
Sans leans against a wall, staring into nothing.
A soft voice breaks the silence.
"You handled that monster better than most."
Tamayo and Yushiro stand there—dark silhouettes in the moonlight.
Tanjiro lifts his head.
"You're… demons."
Tamayo smiles kindly, but her eyes hold centuries of suffering.
"Yes. But not servants of Muzan."
Yushiro snarls, "Stay away from Lady Tamayo!"
Papyrus gasps dramatically.
"WHY WOULD WE TOUCH ANYONE!? MY HANDS ARE BONEY AND UNSATISFYING!"
Sans chuckles weakly.
Even he needed the tension broken.
Tamayo studies Sans with quiet fear.
"You… your soul is unusual."
Sans shrugs lazily.
"You should've seen me last Tuesday."
He steps forward, serious again.
"Tamayo. That Muzan guy… he didn't feel like one demon. He felt like seven."
Her gentle expression finally cracks.
"…Seven?"
Sans nods slowly.
"Seven centers of life. Seven pulses. Seven anchors. You destroy one—he's still got six left."
"Impossible…" Yushiro breathes.
"Not for that monster," Sans replies coldly.
Tanjiro's eyes fill with determination.
"So that's why he can't be killed… yet."
Papyrus slams his fist into his palm.
"THEN WE SHALL DESTROY ALL SEVEN! EASY WORK FOR THE GREAT PAPYRUS!"
Sans snorts.
"Sure, buddy."
Tamayo kneels before Tanjiro.
"Bring me demon blood. Strong demons. I will use it to create a cure. Perhaps one day… your sister will be free."
Tanjiro's voice cracks.
"Thank you…"

Screen 3 – Susamaru & Yahaba Attack
Tamayo invites them inside her hidden home—quiet, peaceful… too peaceful.
Then—
BOOM
The entire building shudders.
Walls crack.
Blood-colored dust drifts from the ceiling.
Yushiro screams, "EVERYONE MOVE!"
A Temari ball bursts through the wall—
fast enough to take off Papyrus's skull if it was an inch higher.
Papyrus yelps,
"WHY IS A CHILD'S TOY TRYING TO END MY EXISTENCE!?"
Another explosion—
The front of the house is ripped open.
Susamaru steps through the smoke, grinning with all six arms ready.
Her eyes gleam with a child's joy and a murderer's thrill.
Yahaba follows her, arrows swirling in the air like invisible blades.
"Lord Muzan demands your deaths," he whispers.
Susamaru giggles.
"Let's play!"
She hurls a Temari ball so fast the air screams.
Sans flicks his finger—
The ball twists midair and smashes into the ceiling, cracking stone.
"Ooooh!" Susamaru squeals.
"You're FUN!"
Chaos erupts.
Tanjiro charges Yahaba, only to be twisted by the arrow markings and thrown sideways.
Papyrus summons bone shields, but the arrows redirect the Temari balls—
smashing him through multiple walls.
"THIS IS NOT HOW SPORTS SHOULD BE PLAYED!"
Sans creates a gravity dome, slowing the deadly storm of Temari balls—but the pressure cracks the floor beneath him.
---
The Counterattack (Darker)
Papyrus roars,
"BROTHER! TANJIRO! NOW!"
Sans yanks Yahaba's arrow patterns downward, exposing his true position.
Tanjiro leaps, blade shimmering like moonlit water.
"Water Breathing… Seventh Form—DROP CUT!"
Yahaba's head flies off—
eyes still blinking in shock.
Susamaru charges, screaming with bloodlust.
Sans teleports behind her, ripping her balance away with a gravity pull.
Papyrus forms a massive bone warhammer—larger than himself.
He swings.
CRACK—
Her arms shatter like twigs.
She shrieks.
Blood sprays.
Tanjiro rushes in.
"Second Form… WATER WHEEL!"
Her head separates cleanly.
Her body collapses.

Screen 4 – End of the Asakusa Arc (Dark Version)
Silence.
Broken wood.
Blood on the floor.
Demonic ash drifting like black snow.
Tanjiro breathes heavily.
"That… was too close."
Papyrus stands on debris like a triumphant warrior.
"FEAR NOT! WE HAVE SAVED THE DAY WITH COURAGE AND BONES!"
Sans leans on a cracked support beam.
"Yeah, but if you fall through, I'm not fishing you out."
Tamayo steps forward, dusted with rubble but unharmed.
"You protected us. Few could survive an attack by Muzan's assassins."
Yushiro glares at Sans.
"You freakish skeleton… how are you this strong?"
Sans shrugs.
"Calcium."
Papyrus beams proudly.
"YES! WE ARE RICH IN MINERALS!"
Tanjiro bows to Tamayo.
"You've given us hope… and a path forward."
"Bring me blood," she says softly.
"And maybe… we can save Nezuko."
Tanjiro trembles.
"…Thank you."
Sans rests a hand on Tanjiro's shoulder.
"We're in this, kid. To the end."
Papyrus nods.
"TOGETHER! WE SHALL DEFEAT EVIL WITH STYLE!"
---
On the Road Again
Hours later, they leave the ruined district behind.
Asakusa's neon lights fade into the dark.
The crow swoops down.
"Village attacked! Head south-southeast!"
Sans cracks his neck.
"Break's over."
Tanjiro steps forward, eyes burning.
"Muzan… next time… I won't freeze."
The three walk into the night—
shadows stretching long behind them—
as the Asakusa Arc ends in darkness.
End of Asakusa Arc – DARK VERSION
