Screen 1 – The Drum Demon's Mansion (Dark Edition)
Fog crawls across the forest floor like living fingers.
The crows aren't even cawing — they just watch.
Tanjiro, Sans, and Papyrus enter the forest, and the stench of blood hangs heavy.
A trembling cry breaks the silence.
A blond boy clutches a girl's kimono so tight his knuckles go white.
"PLEASE MARRY ME! I CAN FEEL DEATH BREATHING DOWN MY NECK!" Zenitsu howls.
Papyrus freezes.
"THIS IS NOT HOW HUMANS COURT EACH OTHER, RIGHT!?"
Sans stares with hollow sockets.
"Pretty sure even demons wouldn't beg like that."
Tanjiro pulls Zenitsu off.
"You're scaring her. Stop… please."
Zenitsu spins and points, horrified at the skeletons.
"WHY ARE THERE MONSTERS WITH YOU!? AM I ABOUT TO GET EATEN!?"
Sans lifts a hand.
"nah. too much effort."
Zenitsu faints so hard his head hits the dirt.
Papyrus sighs.
"WE HAVEN'T EVEN MET THE DEMON YET!"
A rustle.
A blur of muscle and fury.
INOSUKE erupts from the bushes with a roar.
"OUT OF THE WAY! I SMELL BLOOD! I'LL KILL THE DEMON FIRST!"
He charges Sans with both swords ready to carve bones.
Papyrus jumps.
"WHY DOES EVERY HUMAN WANT TO KILL US!?"
Sans teleports behind Inosuke.
"someone needs anger management."
Inosuke screams, delighted.
"THE SKELETON TELEPORTS!? PERFECT! I SHALL SLASH YOU UNTIL YOU STOP EXISTING!"
Tanjiro tries to calm him…
but Inosuke runs off into the dark until his voice melts into the fog.
A child stumbles out of the forest.
"Help!! My brother is in the mansion!"
Blood spatters his clothes.
Everyone freezes.
Even Sans' lazy grin fades slightly.
A mansion looms in the fog — crooked, broken, bleeding from its walls as if the wood itself had veins.
A drum beats inside.
BOOM.
The trees shake.
Papyrus whispers,
"I DO NOT LIKE THIS HOUSE."
Sans steps forward.
"welp. let's clock in."
The door SLAMS shut behind them with a wet, fleshy sound.

Screen 2 – The Drum Demon Fight (Dark Edition)
Kyogai's drums pound.
The entire mansion twists sideways — floors become walls, walls become ceilings.
Bloodstains drip upward.
Papyrus crashes into a sliding door.
"THIS HOUSE VIOLATES EVERY SAFETY RULE EVER!"
Sans drifts, unfazed.
"someone got real creative with interior design."
Footsteps echo…
Kyogai appears in the doorway, claws dragging across the wall, leaving deep bloody gouges.
"More intruders…
Leave your bones behind."
Papyrus poises like a noble knight.
"YOU SHALL NOT HAVE MY BONES, DRUM MAN!"
Kyogai slams a drum.
BOOM
The room rotates.
Papyrus is thrown violently against the ceiling.
Sans hovers in place.
"rude."
Kyogai snarls.
"STOP FLOATING LIKE YOU MOCK ME!"
He slams drums again—
Claws tear through the air in savage arcs.
Papyrus barely dodges.
"THAT COULD HAVE CUT ME IN HALF!"
Sans bends gravity.
Slashes warp off course, slamming into the rotating walls.
Kyogai's eyes widen.
"What… ARE you?"
"just a skeleton with hobbies," Sans shrugs.
Kyogai hits ALL drums—
The world spins.
Blood sprays from where the claws rip into the walls.
A twisted demon laugh fills the room.
Papyrus, bracing, summons a massive bone shield.
"BONE FORTRESS!"
Claws crack it.
Splinters fly like shrapnel.
Sans' eye glows bright cyan.
"alright. my turn."
He snaps his fingers.
Gravity STOPS.
Kyogai freezes in mid-air, suspended, claws inches from Papyrus' face.
Papyrus shouts,
"BROTHER! NEVER DO THAT WITHOUT WARNING!"
Sans points at Kyogai.
"punch him. hard."
Papyrus charges.
"SUPER PAPYRUS SKULL-SMASH!"
CRUNCH
Kyogai smashes through the floor.
But the demon isn't dead.
Tanjiro and Inosuke crash in, both cut and bruised.
"I WANT A PIECE OF HIM!" Inosuke screams.
Kyogai staggers up, blood pouring from his mouth.
He raises every drum…
"This is MY domain… MY art! YOU CANNOT ERASE ME!"
Just as he strikes—
A thunderous streak cuts through him.
Zenitsu, asleep, eyes closed, blade charged with lightning.
"Thunder Breathing… First Form."
SLASH.
Kyogai's torso splits open.
Papyrus gasps.
"THE CRYBABY HAS POWER!?"
Sans whistles.
"man becomes terrifying when unconscious. relatable."
Tanjiro steps forward.
"You fought hard. Your art… was beautiful. But it ends here."
He swings.
Water Breathing — Fourth Form!
One clean cut.
Kyogai's head falls.
Silence.
Blood pools on the floor.
The mansion collapses like a dying beast.

Screen 3 – Aftermath (Dark Edition)
Tanjiro carries the injured boy out of the ruins.
Papyrus carries the older brother heroically.
Skeletons walk through burning debris like ghostly guardians.
Inosuke keeps challenging Sans.
"SKELETON! FIGHT ME! YOU HAVEN'T PROVED YOURSELF!"
Sans flicks his eye.
"kid, I already beat the house. you're not scarier than that."
Zenitsu wakes up, sees the skeletons—
screams—
then faints again.
Papyrus sighs.
"WE SHOULD PUT A SIGN ON HIM THAT SAYS 'DO NOT DISTURB.'"
Tanjiro smiles softly.
"Thank you… all of you."
Papyrus poses.
"THE GREAT PAPYRUS DECLARES THIS ARC—"
Sans finishes for him.
"—brutally completed."
The group walks into the morning light.
Their journey grows darker from here.
