Screen 1 – The Drum Demon's Mansion
Tanjiro, Sans, and Papyrus follow the crow's directions into a foggy forest.
The three stop when they hear something that sounds like crying.
A blond boy sits on the ground, clinging to a girl's kimono.
He's shaking so hard it looks like he might explode.
"PLEASE MARRY ME! I'M ABOUT TO DIE ANY MINUTE!" Zenitsu screams.
Papyrus freezes.
"WHAT SORT OF PROPOSAL IS THIS!?"
Sans squints.
"Man's got negative rizz."
Tanjiro tries to pull Zenitsu off the girl.
"Zenitsu, you're scaring her. Please stop!"
Zenitsu spins around.
"OH—TANJIRO!? WHY ARE YOU WITH TWO SKELETONS!? AM I HALLUCINATING!?"
Sans waves.
"Heya."
Zenitsu faints on the spot.
Papyrus sighs. "THIS ARC IS GETTING WEIRDER!"
Before Tanjiro can respond, the forest shakes.
A boar-headed figure jumps out of the bushes, roaring.
"OUT OF MY WAY! I FOUND A STRONG DEMON!"
Inosuke Hashibira charges straight at Sans and Papyrus with his twin swords.
Papyrus yelps.
"WHY IS EVERYONE ATTACKING US ON SIGHT!?"
Sans teleports behind Inosuke.
"Chill."
Inosuke stumbles, spins, then screams again.
"HE TELEPORTED! THIS SKELETON IS STRONG! LET ME FIGHT HIM!"
Tanjiro steps between them.
"Stop! We're Demon Slayers, not enemies! Please calm down!"
Inosuke doesn't calm down.
He charges again.
Papyrus blocks him with a bone shield that materializes in midair.
"I AM NOT A TRAINING DUMMY!"
Inosuke howls.
"I WANT A REMATCH LATER!"
Sans shrugs.
"Sure. Knock yourself out."
Tanjiro pulls Zenitsu back to his feet.
"Guys… we need to focus. There's a demon nearby. A strong one."
They hear a scream from deeper in the woods.
Then they see it.
A giant mansion sitting in the trees, its walls creaking like something alive.
A terrified boy runs out of the front door shouting:
"HELP! MY BROTHER'S STILL INSIDE!"
The ground shakes.
A deep drumbeat echoes from inside the house.
Papyrus shivers.
"That does not sound friendly."
Sans sighs.
"Guess we're going in."
Tanjiro looks at Zenitsu and Inosuke.
"You three stay close. No running off."
Inosuke immediately runs off.
"I'M GOING FIRST!"
Zenitsu screams and runs after him, terrified.
Papyrus chases both of them.
"TANJIRO, THEY ARE CHILDREN!"
Sans teleports inside like he's clocking in for work.
"Let's get this over with."
Tanjiro enters last, gripping his sword.
The door slams shut behind them.
The drums start beating again.
The entire mansion twists and rotates like a nightmare
Screen 2 – The Drum Demon Fight
The mansion slams sideways as Kyogai hits one of his drums.
Walls spin. Floors flip.
Everyone scatters into different rooms.
Papyrus crashes through a sliding door and rolls across the floor.
"WHO DESIGNED THIS HOUSE!? THIS IS NOT SAFE!"
Sans drops in right after him, floating casually.
"Demon with anger issues. That's my guess."
A heavy set of footsteps echoes from the hallway.
Kyogai, the Drum Demon, steps into view—drums embedded in his body, eyes burning with frustration.
"You dare invade my domain…? I will turn you into scraps."
Papyrus strikes a pose.
"SCRAPS? I AM A SKELETON OF GREATNESS! PREPARE YOURSELF!"
Kyogai slams a drum on his chest.
BAM
The entire room rotates 90 degrees.
Papyrus falls sideways and hits the wall.
"THIS IS CHEATING!"
Sans lands lightly, not even stumbling.
"Buddy. Your house is making me dizzy."
Kyogai glares.
"Stop mocking me."
---
In another room…
Tanjiro and Inosuke land in a hallway that flips to the ceiling every few seconds.
Inosuke laughs.
"THIS HOUSE IS AWESOME! LET ME FIGHT THE DEMON FIRST!"
Tanjiro keeps his balance.
"We all need to work together. This demon has a tricky Blood Art!"
Inosuke ignores him and sprints off.
---
Meanwhile… Zenitsu
Zenitsu crawls on the floor, shaking.
"I don't want to be in this house… I don't want to be here… why is everything spinning… why is there a skeleton chasing me…?"
Papyrus' voice echoes from far away.
"ZENITSU! COME BACK! YOU MUST FACE YOUR FEARS!"
Zenitsu screams and runs faster.
---
Back to Sans & Papyrus vs Kyogai
Kyogai slams his shoulder drum.
BAM
Dozens of razor-sharp claw slashes cut through the air.
Papyrus narrowly dodges.
"THAT IS VERY RUDE, DRUM MAN!"
Sans flicks his wrist.
Gravity bends.
The claws distort and miss.
Kyogai snarls, turning his attention to Sans.
"What… are you?"
Sans shrugs.
"Someone who doesn't like noisy neighbors."
Kyogai hits two drums at once.
The entire mansion spins vertically while claw slashes tear through every direction.
Papyrus plants his feet and summons a massive bone shield.
"BONE WALL!"
The claws slam against it, cracking it but not breaking through.
Sans floats upward, eye glowing bright.
"Alright. Enough games."
Kyogai panics and hits every drum on his body—
rooms rotate, gravity flips, attacks fly everywhere.
Papyrus yells, "BROTHER, THIS IS GETTING OUT OF HAND!"
Sans raises a finger.
"Shhhh."
Gravity snaps into place.
All rotating stops.
Kyogai freezes mid-motion, suspended in blue light.
Papyrus gasps.
"BROTHER! THAT WAS VERY COOL!"
Sans nods.
"Thanks. Now punch him."
Papyrus charges, fist glowing bright white.
"SUPER PAPYRUS PUNCH!"
CRACK
Kyogai slams into the floor.
But before they finish him—
The walls around them explode.
Tanjiro and Inosuke jump in.
Inosuke screams, "I WANT TO FIGHT TOO!"
Tanjiro yells, "Stop! Don't hit the others—focus on the demon!"
Kyogai, injured but alive, leaps back and prepares his strongest attack.
"This is my domain… my music… my art! I WILL NOT LOSE!"
He raises both arms to slam all drums at once—
But a yellow blur streaks through the room.
Zenitsu, half-asleep, bolts into action.
"Thunder Breathing… First Form…"
A single slash cuts through the air.
Kyogai staggers.
Papyrus shouts, "ZENITSU FINALLY DID SOMETHING!"
Sans grins.
"Amazing what he can do when he's unconscious."
---
Finishing Blow
Tanjiro steps forward, eyes sharp.
"Your art… deserves respect. But it ends here."
He takes a breath.
"Water Breathing… Fourth Form!"
His blade cuts clean through Kyogai's neck.
The demon falls silent.
Drums stop beating.
The mansion settles.
---
Papyrus stands tall.
"WE DID IT! A TEAM OF HEROES!"
Sans sits on a piece of rubble.
"Yeah. Nice work, everyone."
Zenitsu wakes up confused.
"Huh? Did we win… or did I die?"
Inosuke shouts, "SKELETON! FIGHT ME NOW!"
Tanjiro sighs.
"This is going to be a long journey."
Screen 3 – End of the Tsuzumi Mansion Arc
The mansion finally stops shaking.
The broken halls settle, dust drifting through the faint morning light.
Tanjiro helps the terrified boy, Shoichi, out of the rubble.
"Your brother is safe now. Let's take him home."
Shoichi nods, still shaky.
"Th-thank you…"
Papyrus lifts another child under one arm.
"FEAR NOT, SMALL HUMAN! THE GREAT PAPYRUS SHALL CARRY YOU TO SAFETY!"
Sans casually floats behind them, using tiny gravity lifts to clear debris.
"Careful. Some of these boards look like they're one sneeze away from collapsing."
Inosuke stomps out of the mansion with a bruised ego.
"HEY! DON'T WALK AHEAD OF ME! I'M THE LEADER!"
Sans raises a hand lazily.
"Sure, man. Lead the way."
Inosuke puffs up his chest…
then immediately walks into a tree.
Papyrus whispers to Tanjiro, "HE IS VERY ENTHUSIASTIC."
Zenitsu drags himself out, whining loudly.
"Why… why do demons have mansions with drums and spinning floors…? Why is there a skeleton floating behind me…?"
Sans pats his shoulder.
"Don't worry. I'm just haunting you a little."
Zenitsu faints again.
---
On the Road
Once they leave the destroyed mansion behind, the forest feels peaceful again.
Tanjiro carries Shoichi gently.
Papyrus carries the older brother with heroic pride.
Zenitsu wakes up and immediately screams when he sees the skeletons again.
Inosuke keeps trying to fight Sans for no reason.
Sans just keeps walking.
"One day he'll get tired. Right?"
Tanjiro laughs softly.
"I don't think so."
Papyrus poses dramatically.
"THE GREAT PAPYRUS DECLARES THIS ARC COMPLETE!"
Sans smirks.
"Yeah… Tsuzumi Mansion is over."
The group keeps walking down the dirt road, ready for whatever comes next.
Tsuzumi Mansion Arc – Complete
