Screen 1 – Muzan in Asakusa
Tanjiro, Sans, and Papyrus arrive in the bright, crowded streets of Asakusa.
Neon lights. Food stalls. Laughter everywhere.
It's the first time Sans and Papyrus see a modern city.
Papyrus scans the shops with sparkly eyes.
"LOOK AT ALL THESE BEAUTIFUL BUILDINGS! THE GREAT PAPYRUS APPROVES!"
Sans munches a steamed bun. "Not bad. Could use more ketchup."
Tanjiro smiles. "Stay close. Demons hide anywhere."
He pauses.
His nose twitches.
A scent hits him like a punch.
That scent.
The same scent from the night his family was slaughtered.
Tanjiro freezes.
His eyes widen with terror and rage.
Sans notices instantly. "Kid. What's wrong?"
Tanjiro whispers, "He's here."
Before Sans can ask, Tanjiro runs through the crowd.
Papyrus chases after him. "TANJIRO! WAIT!"
Sans teleports ahead of them.
---
The Encounter
Tanjiro stops in front of a tall man wearing a white suit.
Calm expression.
Perfect posture.
Holding the hand of a small human child.
Muzan Kibutsuji turns his eyes toward Tanjiro with a slow, cold interest.
Papyrus stumbles behind Tanjiro. "Who's the fancy man?"
Sans looks at Muzan.
His smile fades.
His eye narrows just a bit.
"Something's off about this guy."
Tanjiro points his sword toward Muzan, voice shaking.
"You… you're the one… You killed my family!"
People look around, confused.
Some laugh, thinking it's a performance.
Muzan simply smiles.
"Lower your voice. I am a normal human."
To prove it, Muzan scratches a passerby's neck—
and instantly turns the man into a demon.
Screams erupt.
Papyrus jumps back. "WHAT IN THE NAME OF SPAGHETTI!?"
Sans steps forward, eyes glowing faintly blue.
"You're no human."
Muzan's gaze sharpens.
He studies Sans and Papyrus like rare animals.
"Interesting. You two… you are not human either."
Sans shrugs casually.
"Neither are you, pal."
The air turns heavy.
Muzan's killing intent pours out, crushing the atmosphere.
Tanjiro grits his teeth. "Muzan… I swear… I will defeat you."
Muzan doesn't look threatened.
He turns to leave with his fake family.
"You're welcome to try."
But as Muzan steps away, Sans teleports in front of him—quiet, serious.
"Don't mess with my kid."
For the first time, Muzan pauses.
Papyrus yells from behind, "SANS! WHAT ARE YOU DOING!?"
Muzan's expression shifts to annoyance.
He flicks his fingers.
A wave of demon energy blasts outward.
Sans plants his feet, blocking the pressure with a blue flash.
Tanjiro grabs Sans' arm. "Sans—no! Not here! There are too many civilians!"
Sans grits his teeth but backs away.
Muzan vanishes into the crowd, gone in a heartbeat.
---
Tanjiro falls to his knees, hands shaking.
Papyrus puts a hand on Tanjiro's back.
"Do not worry! With us here, you shall face him again!"
Sans looks at the spot where Muzan disappeared.
"…he's dangerous. Real dangerous."
Tanjiro breathes deeply.
"I will hunt him down… no matter what."
The three stand together in the center of the chaotic street.
Screen 2 – Lady Tamayo and Yushiro
The chaos in Asakusa slowly fades as the injured are taken to safety.
Tanjiro sits on the edge of an alleyway, still shaken from facing Muzan.
Papyrus tries to comfort him with encouraging words.
Sans leans against a wall, silent for once.
A soft voice breaks the tension.
"You handled that situation well, despite the danger."
They turn to see a gentle-looking woman in a purple kimono.
Beside her stands a young man with an irritated scowl.
Tanjiro blinks. "Who are you?"
The woman bows politely.
"My name is Tamayo. And this is Yushiro."
Yushiro glares. "Don't touch Lady Tamayo. Don't even breathe near her."
Papyrus gasps. "WE ARE NOT BREATHING NEAR ANYONE! WE BREATHE WITH DIGNITY!"
Sans snickers. "Relax, man. Nobody's touching your lady."
Tamayo steps closer, observing the three of them with calm eyes.
"I sensed Muzan's presence earlier. You confronted him… and survived."
Her gaze sharpens. "That alone is impressive."
Tanjiro nods. "You're a demon… but you're not attacking us."
"Correct," she says. "I freed myself from Muzan's control long ago. I am on your side."
Yushiro crosses his arms. "We're helping humans. Deal with it."
Sans steps forward, his expression serious.
"Hey, Tamayo. You've studied demons for a long time, right?"
"I have," she replies.
"I've been thinking…" Sans says. "That demon king… Muzan. He didn't feel like he had one weak spot."
Tanjiro looks up. "What do you mean?"
Sans taps his chest.
"Most monsters… heck, most demons… they've got one soul, one core, one place you aim for."
He shakes his head.
"But Muzan? He felt like he had… multiple. Like seven different centers of energy pulsing at once."
Tamayo's eyes widen slightly.
"Seven…?"
Yushiro frowns. "That's absurd. No demon has more than—"
Tamayo raises a hand. "Yushiro. Be quiet."
Sans continues, voice low.
"It wasn't his heart, or his brain. It felt like seven anchors keeping him alive. If you destroy only one, the rest keep him running."
Tanjiro's eyes burn with determination.
"So that's why he's impossible to kill…"
Papyrus slams his fist into his palm.
"THEN WE MUST FIND ALL SEVEN AND DESTROY THEM! EASY FOR THE GREAT PAPYRUS!"
Sans smirks.
"Yeah. Easier said than done."
Tamayo kneels beside Tanjiro.
"If what your friend says is true, it changes everything. You cannot kill Muzan with a single strike. You must sever all sources of life at once."
Tanjiro clenches his fists.
"Then we'll do it. One day… we'll bring Muzan down."
Sans nods. "We'll figure out the pattern. Seven hearts. Seven targets."
Yushiro sighs. "This is insane…"
Tamayo smiles gently.
"Perhaps fate has brought us curious allies today."
---
The night deepens.
But their path forward becomes clearer than ever.
Screen 3 – Susamaru and Yahaba Attack
Tamayo invites Tanjiro, Sans, and Papyrus into her hidden home.
The place is quiet and peaceful, with soft lantern light and the smell of herbs.
Papyrus looks around proudly.
"A LOVELY HOME! MUCH MORE WELCOMING THAN THAT SWAMP!"
Sans kicks off his slippers and sits on a cushion.
"Yeah. Feels nice."
Tanjiro bows to Tamayo.
"Thank you for helping us."
But before she can answer—
A loud boom shakes the entire building.
Glass cracks.
Wood splinters.
The house trembles like it's been hit by a cannon.
Yushiro shouts from the hallway, "EVERYONE MOVE!"
A massive Temari ball smashes through the wall, inches from Papyrus' head.
Papyrus yelps, "WHAT KIND OF DEMON USES SPORTS EQUIPMENT AS WEAPONS!?"
Another crash tears open the front wall.
Two demons step into view.
A girl with a wicked grin, six arms, and deadly Temari balls.
Susamaru.
And beside her, a calm man with closed eyes, red arrows trailing from his palms.
Yahaba.
Yahaba speaks softly.
"Lord Muzan orders your destruction."
Susamaru laughs like it's a game.
"Let's play!"
She hurls a Temari ball with insane force.
Sans steps forward, eye glowing.
"Kid, duck."
Tanjiro drops low as Sans changes the ball's direction midair with a gravity twist—sending it crashing back through the ceiling.
Susamaru's grin widens.
"Ooooh! You're fun!"
Papyrus jumps into action, bone shield raised.
"I, THE GREAT PAPYRUS, SHALL DEFEND THIS HOUSE!"
Yahaba lifts his hand.
"Redirection."
Invisible arrow markings glide across the room, pulling Susamaru's next Temari ball toward Papyrus at impossible speed.
The impact sends Papyrus flying through a table.
"NO FAIR! I WASN'T READY!"
Tanjiro rushes toward Yahaba.
"I'll take him!"
Yahaba drags his arrows across the floor, twisting Tanjiro's direction mid-run.
Sans teleports beside Tanjiro and stabilizes him.
"Focus. Follow the arrows. Predict the path."
Tanjiro nods.
"Right!"
---
Susamaru vs Papyrus
Susamaru fires three Temari balls at once.
Papyrus summons rows of bones in midair.
"BONE BARRAGE!"
The bones clash with the Temari balls and explode like fireworks.
Susamaru leaps forward, laughing.
"Fun! Fun! FUN!"
Papyrus dodges with surprising agility.
"STOP HAVING FUN TRYING TO KILL ME!"
---
Tanjiro vs Yahaba
Tanjiro swings his sword, trying to counter Yahaba's invisible arrows.
But they keep twisting his body off-balance.
"Water Breathing… Fifth Form!"
He cuts through several arrows, but more appear instantly.
Yahaba smirks.
"You are helpless."
Tanjiro grits his teeth.
"No… I'm learning your pattern."
---
Sans vs Susamaru
Susamaru turns her attention to Sans.
"You! Blue-eye! Fight me!"
Sans scratches his head.
"Alright. Why not."
She throws a Temari straight at him.
Sans flicks his finger.
The ball freezes in midair.
Susamaru's eyes widen.
"Huh?"
Sans fires a tiny Gaster Blaster and vaporizes the Temari.
"That's strike one."
Susamaru screams and launches all her balls at once, the air turning into a storm of spinning death.
Sans sighs.
"This is gonna be annoying."
He creates a gravity dome, slowing all the balls while Papyrus and Tanjiro reposition.
---
The Counterattack
Papyrus shouts, "BROTHER! TANJIRO! LET US COMBINE OUR MIGHT!"
Tanjiro uses the slowed arrows to read Yahaba's position.
Sans shouts, "Now!"
Tanjiro leaps.
"Water Breathing… Seventh Form!"
He slices Yahaba's head clean off before the arrows can twist him away.
Papyrus charges Susamaru.
"I SHALL END THIS GAME!"
Sans teleports behind her and drops her guard with a gravity pull.
Papyrus swings a massive bone hammer—
CRACK
Her arms snap.
Her Temari falls.
Tanjiro dashes in.
"Water Breathing… Second Form!"
Her head is severed.
Both demons collapse.
---
Tamayo steps out of the ruins of her home, calm but shaken.
"You protected us well."
Yushiro looks at Sans with pure confusion and annoyance.
"…how is that skeleton stronger than me?"
Sans shrugs.
"Good bones."
Tanjiro exhale with relief.
Papyrus stands proudly, hands on hips.
"ANOTHER TRIUMPH FOR OUR HEROIC TEAM!"
Screen 4 – End of the Asakusa Arc
The dust settles.
Tamayo's home is half-destroyed, with broken wood and cracked floor tiles everywhere.
But everyone inside is alive.
Tanjiro wipes the sweat from his forehead.
"That was… intense."
Papyrus plants his foot on a fallen beam like a victorious hero.
"FEAR NOT! THE GREAT PAPYRUS HAS PROTECTED EVERYONE WITH STYLE!"
Sans leans against a wall that's barely standing.
"Yeah… but maybe don't pose on the rubble. It might fall."
Tamayo steps toward them, calm as ever despite the chaos.
"Thanks to you three, Yushiro and I survived Muzan's assassins. You've done more than most Demon Slayers would dare."
Yushiro glares at Sans.
"Tch. Don't get cocky. You're just… a weird skeleton."
Sans shrugs.
"Hey. I prefer 'cool skeleton,' but whatever."
Papyrus puffs out his chest.
"YES! WE ARE VERY COOL!"
Tanjiro bows deeply to Tamayo.
"We're glad you're safe. You helped us more than we helped you."
Tamayo smiles.
"You gave me something I haven't felt in years… hope."
She places her hand gently over Tanjiro's.
"Bring me the blood of strong demons. With it, I can create a cure. Your sister Nezuko may be saved one day."
Tanjiro's voice shakes with gratitude.
"Thank you… I won't waste this chance."
Sans watches him quietly.
Papyrus rests a hand on Tanjiro's shoulder.
"WE SHALL HELP YOU ON THIS QUEST!"
Yushiro sighs loudly.
"Why are these skeletons so dramatic?"
---
On the Road Again
A few hours later, the three leave Asakusa behind.
The city lights fade.
The night breeze cools the streets.
Their footsteps echo as they head toward their next mission.
Tanjiro looks ahead with determination.
"Next time I see Muzan… I won't freeze."
Sans walks beside him.
"Yeah. And we'll be there."
Papyrus marches proudly.
"TOGETHER, WE SHALL DEFEAT EVIL AND LOOK AMAZING DOING IT!"
As they reach the edge of Asakusa, a crow swoops down and lands on Tanjiro's shoulder.
"Next mission! South-southeast! Village attacked!"
Sans stretches.
"Back to work, huh?"
Tanjiro nods.
"Asakusa… is behind us now."
The three continue down the moonlit road as the Asakusa arc comes to an end.
End of Asakusa Arc
To be continued…
