Screen 1 – The Surface Battle Begins
The Infinity Castle shatters like broken glass, raining debris across the city.
A massive shockwave blasts through the streets as Muzan steps out of the wreckage.
His body pulses with shifting flesh and red veins, every movement radiating overwhelming demonic power.
His presence alone freezes the air.
Muzan stands tall, eyes glowing like burning coals.
"The night is eternal… and I am its god."
The surviving Hashira land around him:
Giyu
Sanemi
Obanai
Mitsuri
Gyomei
Behind them, Tanjiro rises to his feet, breathing hard but unbroken.
"We're not running," he says. "We'll bring the sun to you."
Muzan turns toward him, annoyed.
"Your struggle is pointless."
Sans appears beside Tanjiro, hands in his pockets.
"man… you talk so much."
Papyrus drops in behind him, pointing dramatically.
"MUZAN! YOUR MONOLOGUE IS TOO LONG! PLEASE SHORTEN IT FOR EVERYONE'S SAKE!"
Muzan glares at the brothers, veins twitching with rage.
The demon slayers surround him.
The final war has begun.
The Sunrise Countdown starts now.
Screen 2 – The Unholy Monster
Muzan's body mutates the moment he steps onto the surface.
His skin twists.
His shape swells.
His arms stretch into long, whip-like tendrils that slam through the ground with impossible speed.
He becomes a shifting, living storm — faster than any Upper Moon, stronger than any demon before him.
Gyomei blocks a strike with his axe, the force throwing him back.
Sanemi dodges another tendril by inches.
Mitsuri flips away, barely avoiding being crushed.
Obanai rushes forward to cut one whip, but it regenerates instantly.
Papyrus yelps as a tendril smashes a crater into the road where he just stood.
"THAT WAS WAY TOO CLOSE!!"
Sans lands beside him, both eyes glowing now — something he almost never does.
"yeah… this guy's on a different level."
---
Tamayo's Drug Starts Working
But then, a strange ripple moves across Muzan's body.
Wrinkles spread across his skin.
The tendrils slow for a second.
His movements stutter.
Gyomei notices it first.
"Tamayo's medicine… it's weakening him."
Sanemi spits blood and smirks.
"So we don't need to beat him… just hold him here!"
Mitsuri nods.
"Until sunrise! We just have to last!"
Tanjiro grips his sword tight.
"We can do this! Don't stop moving!"
---
Sans Uses 100% Power
A whip slams at Tanjiro.
Sans teleports in and blocks it with a massive energy blast.
His whole skeleton glows with intense blue light.
He finally stops holding back.
"alright.
no more jokes."
Papyrus gasps.
"BROTHER! YOU'RE USING ALL YOUR POWER!?"
Sans nods slightly.
"yeah.
this is our last shot."
He summons a huge field of blasters that roar to life behind him, lighting up the battlefield like artificial sunrise.
The Hashira stare for a moment — even Muzan's eyes widen.
Tanjiro breathes in sharply.
"Sans…!"
Sans keeps his gaze locked on Muzan.
"don't get excited.
this won't kill him.
it's just buying time."
---
The Hashira regroup.
Tanjiro steadies his stance.
Papyrus builds bone barriers around civilians trying to escape.
The final battle truly begins.
Screen 3 – Scene 3: The Battle of Time — "Hold Him Until Dawn"
The battlefield shakes under Muzan's monstrous roar.
His body lashes out in every direction, a storm of tendrils and distorted muscle.
But the Demon Slayer Corps refuses to back away.
Gyomei plants his feet like a mountain.
"BREATHE! HOLD THE LINE!"
Sanemi charges beside him, wind slicing forward like storms.
"You're not going anywhere, monster!"
Together, they push against Muzan's overwhelming force, giving the others precious seconds.
Obanai and Mitsuri dive between the tendrils, cutting off parts of Muzan's body to slow him down.
Every attack costs them something.
Every movement hurts.
But they smile through it.
Giyu joins Tanjiro at the front.
Water and flame spin together.
"Tanjiro, don't lose focus!"
"I won't!"
Muzan roars, furious as Tamayo's drug keeps wearing him down little by little.
The Hashira shout together:
"We don't need to kill him!
We just need to reach sunrise!"
---
Scene 4: One by One, They Fall
Muzan grows more desperate.
His strikes shake the entire battlefield, sweeping everything aside with brutal force.
Even so…
No Hashira retreats.
Mitsuri takes a final blow while protecting Obanai.
Her smile is soft.
"Everyone's still fighting…
It's beautiful…"
Obanai catches her, refusing to let her fall alone.
"If we're reborn…
I'll find you again."
They stay close as the first hints of dawn touch the sky.
---
Sans and Papyrus: Full Power, Full Rage
When the two brothers see Hashira falling, something snaps inside them.
Papyrus ignites with blazing orange energy—
brighter than ever before.
"NO MORE!
NO MORE SUFFERING!
THE GREAT PAPYRUS…
WILL NOT LET YOU HURT ANYONE ELSE!"
Every bone he summons glows like a sun, towering and fast enough to block Muzan's strikes.
Sans closes his eyes for a moment.
Then his blue flame burns brighter than ever.
He steps forward, quiet and cold.
"alright, freak.
that's enough."
He unlocks everything.
No joking.
No laziness.
No holding back.
Gravity blasts hit Muzan from every angle.
Gaster Blasters fire nonstop, creating space for the Hashira to breathe.
Papyrus stands beside his brother.
Sans growls:
"we hold him."
Papyrus shouts:
"UNTIL SUNRISE!"
Together, the brothers unleash 100 percent of their strength—
not to win…
but to buy time for everyone still fighting.
The countdown to dawn continues.
Version)
Tanjiro can barely stay upright.
He's hurt, tired, and pushed far past his limit — but he refuses to stop.
He steadies his breathing.
He focuses his mind.
And then, for the first time, he moves through all thirteen forms of Hinokami Kagura in one unbroken flow.
Flames spin around him like a rising sun.
Muzan tries to escape through the rubble, but Tanjiro reads every movement.
With one final effort, Tanjiro drives his blade into Muzan's center — not to destroy him, but to keep him from escaping before dawn arrives.
Muzan snarls, furious that a human cornered him.
"You are my legacy," Muzan growls.
"You carry everything I am."
Tanjiro ignores the words.
He holds the blade with every bit of strength he has left.
All he wants is for the sun to rise.
---
Scene 6: The Dawn (Safe Version)
Light touches the battlefield.
The first hint of sunrise glows over the broken city.
The change hits Muzan instantly.
His power fades.
His strength collapses.
The substance holding his form together starts breaking apart.
He tries to flee, desperate, but the Hashira and every remaining slayer block his path.
The light grows brighter.
Muzan cannot hold himself together anymore.
Just before he loses control completely, he lashes out with one final act of hatred.
A surge of his remaining power rushes toward Tanjiro — not a strike, but an attempt to force his own essence into him.
Tanjiro is too exhausted to move away.
The wave hits him.
For a moment, everything goes silent.
Then Muzan's form finally dissolves in the growing daylight, leaving Tanjiro collapsing into the arms of his friends.
The sun rises fully.
Muzan is gone.
But a new fear begins.
Tanjiro isn't waking up.
Something has changed.
Screen 6 – Demon King Tanjiro
Scene 7: Tanjiro's Struggle Against Muzan
The battlefield settles into silence after Muzan's fall.
The air is heavy with dust and morning light.
Tanjiro, lying in the rubble, suddenly moves.
His body tenses.
His skin pales.
Strange marks cross his face.
Everyone realizes it at the same time:
Muzan forced his power into Tanjiro.
The last spark of the Demon King lives inside him.
The other Hashira can't stand anymore.
Their bodies are exhausted.
Their breathing is unsteady.
Tanjiro rises, but not like himself—
his movements are stiff, confused, almost controlled by another presence.
Nezuko, now human again, sees him and rushes forward.
"Brother! Please, come back!"
Her voice shakes.
Her hands tremble.
Tanjiro turns toward her—
and for a moment, Muzan's influence pulls him away from himself.
---
Inside Tanjiro's Mind
In Tanjiro's soul, a battle is happening:
Muzan's voice tries to drown everything out.
"You belong to me now."
But Tanjiro sees the faces of everyone he loves:
Nezuko reaching for him
Giyu standing beside him
Rengoku smiling proudly
The friends and Hashira who gave everything
These memories push back the darkness.
Tanjiro grips the last piece of himself.
"No… this isn't me."
---
Sans and Papyrus Reaction
Sans steps forward carefully, keeping his distance.
His eye glows, not in attack mode, but in focus.
"kid…
fight it.
you're stronger than him."
Papyrus stands behind Nezuko, holding her steady.
"NEZUKO, DON'T WORRY!
YOUR BROTHER CAN HEAR YOU!
HE JUST NEEDS A LITTLE MORE HOPE!"
Sans raises a hand, but instead of firing a blaster, he uses a soft gravity pulse—
not to harm Tanjiro,
but to keep Muzan's influence from pushing him closer to others, giving Tanjiro space to resist.
Papyrus forms a bone shield around the injured Hashira to protect them.
"NO ONE WILL GET HURT WHILE TANJIRO FIGHTS INSIDE HIS MIND!"
They don't attack.
They don't force him.
They just buy him time.
Time to choose.
---
Tanjiro Breaks Free
Tanjiro sees Nezuko's tears.
He remembers the warmth of their home.
The promise he made when their journey began.
The reason he kept fighting.
He pushes back with everything he has.
The curse inside him breaks like a cracked shell.
Muzan's voice fades into nothing.
The demonic changes fade.
Tanjiro collapses into Nezuko's arms—
human again.
"I'm home, Nezuko…"
Nezuko hugs him tightly, crying with relief.
Sans sighs softly.
"told you, kid.
you're tougher than any curse."
Papyrus raises his arms triumphantly.
"HE'S BACK!
THE POWER OF FAMILY HAS PREVAILED!!"
The long night is finally over.
Screen 7 – Scene 8: The End of the Demons
The battlefield is quiet for the first time in centuries.
As Muzan fades from the world, every demon connected to him disappears as well.
The curse finally breaks.
For the first time in their lives, the Demon Slayer Corps feels a morning with no fear behind it.
Tanjiro rests beside Nezuko, both exhausted but alive.
The survivors gather:
Giyu
Sanemi
Kanao
Inosuke
Nezuko
Tanjiro
Their bodies are battered, but their hearts are steady.
They watch the sunrise rise over the ruins of the city — not as fighters, but as people who made it through.
---
Sans and Papyrus' Final Decision
Sans stands behind the group, hands in his pockets.
He looks at the rising sun with a soft, tired smile.
Papyrus wipes imaginary sweat from his skull, relieved.
"WE MADE IT…
THE GREAT PAPYRUS… HAS SURVIVED THE FINAL BATTLE!!"
Sans nudges him.
"yeah, bro.
we did alright."
Papyrus looks at Tanjiro and Nezuko hugging each other.
"BROTHER… SHOULD WE GO BACK TO OUR UNIVERSE NOW?"
Sans thinks for a moment.
He watches the Demon Slayer world:
• The quiet fields
• The sunrise
• The people rebuilding
• Tanjiro smiling through the exhaustion
Finally, Sans shrugs lightly.
"nah.
i think we'll stick around.
at least for a while."
Papyrus brightens instantly.
"REALLY!?
WE GET TO LIVE HERE WITH OUR FRIENDS!?"
Sans nods.
"tanjiro and his crew could use some help rebuilding…
and maybe this world could use a few skeletons who know how to keep things peaceful."
Papyrus pumps his fist.
"THEN IT'S DECIDED!
THE GREAT PAPYRUS…
WILL BE A HERO OF THIS WORLD TOO!"
Tanjiro overhears and smiles warmly.
"We're glad to have you both with us.
You're family now."
Sans gives a small wave.
"heh.
guess we are."
---
The End
The war against demons is finally over.
The sunrise is warm.
The survivors breathe freely.
The world begins to heal.
And in this peaceful new era…
Tanjiro, Nezuko, and their friends walk into the future —
joined by two skeleton brothers who found a new home.
The End.
