Screen 1 — The Mystery Portal
Sans and Papyrus are sitting on their couch in Snowdin, watching a cheesy detective show.
Papyrus points at the screen.
"NYEH! THE BUTLER CLEARLY DID IT. HE HAS SHADY VIBES."
Sans yawns.
"heh. maybe. or maybe you just really hate butlers."
Suddenly, the TV glitches. Static floods the screen.
The room shakes. A swirling portal tears open right in front of them.
Papyrus gasps and jumps to his feet.
"WHAT IS THIS?! A SECRET LEVEL OF THE SHOW?"
Sans' smile tightens.
"uhh… that ain't part of the program, bro."
A violent pull grabs them.
Furniture lifts off the ground.
Papyrus flails as he's dragged toward the portal.
"WAIT WAIT WAIT. I HAVE NOT PREPARED FOR AN INTERDIMENSIONAL JOURNEY TODAY!"
Sans tries to brace himself, but the force is too strong.
"man… humans really need to stop breaking reality."
The portal swallows them whole.
Screen 2 — Welcome to Shiganshina
Sans and Papyrus tumble out of the portal and land hard on dusty stone pavement. The sky is gray. Smoke rises in the distance. Alarms echo across the district.
Papyrus sits up, rubbing his skull.
"OW! MY BEAUTIFUL BONES. WHO DESIGNS PORTALS WITHOUT SAFETY RAILINGS?"
Sans groans and stands.
He looks around at the towering stone walls and terrified civilians running past.
"yeah… this ain't snowdin."
A shadow falls over them.
Papyrus turns and freezes.
Right behind them, a Titan crashes through a nearby building.
Huge. Drooling. Hungry.
Papyrus' eyes widen.
"THAT IS NOT A HUMAN. THAT IS NOT EVEN A NICE MONSTER. WHAT IS THAT THING?!"
Sans stares for a second.
His eye flickers blue.
"…welp. guess we're on the menu."
The Titan roars, stepping toward them.
Papyrus panics, trying to look brave.
"S-SANS? ANY BRIGHT IDEAS?"
Sans cracks his knuckles.
"yeah. don't get eaten."
Blue energy sparks in his hands as the Titan lunges—
Screen 3 — The Day Everything Falls
A massive explosion shakes the air. Heat blasts across the rooftops.
Papyrus turns toward the outer gate and screams.
"WHAT IS THAT RED GIANT?! WHY IS HE SO… STEAMY?"
The Colossal Titan towers above Wall Maria.
Its kick blows the gate apart in one strike.
The shockwave knocks Sans and Papyrus off their feet.
Stone and fire rain from the sky. People run in every direction.
Sans gets up slowly.
"…that is a big guy."
Titans rush through the breach.
Hungry faces. Grabbing arms.
Shiganshina turns into a nightmare in seconds.
Papyrus freezes when he spots three kids trapped under fallen debris.
A boy with wild eyes.
A quiet girl pulling on the rubble.
A terrified blond shaking and crying.
Papyrus sprints toward them.
"CHILDREN. DO NOT PANIC. THE GREAT PAPYRUS WILL SAVE YOU."
He lifts the debris with surprising strength.
The kids crawl free. The blond stumbles and Papyrus steadies him.
Sans watches the chaos spread.
His eyelight burns bright blue.
More Titans flood in.
Another explosion.
The Armored Titan charges through the next gate and shatters it like a door made of paper.
Humanity loses ground in one horrible instant.
Sans looks at the three kids.
"names?"
The boy answers through gritted teeth.
"Eren."
The girl steps closer, protective.
"Mikasa."
The blond tries to stay brave.
"A-Armin."
Papyrus beams.
"HELLO TINY HUMANS. WE ARE HERE TO HELP."
Sans steps forward, hands glowing.
"alright. no one dies today."
They stand between the kids and the advancing Titans.
Screen 4 — The Moment That Breaks Him
Sans and Papyrus guide Eren, Mikasa, and Armin through the crumbling streets. Titans trample buildings behind them. Screams everywhere.
They reach a house crushed under fallen beams.
A woman is trapped. A mother.
Eren stops dead.
"MOM!"
Papyrus tries to lift the debris, but it's wedged too deep.
He strains. Bones creak.
"IT'S TOO HEAVY… I… I CAN'T!"
Sans steps forward, eye already glowing—
But a Titan drops down in front of them like a nightmare come true.
The mother looks at Eren, tears in her eyes.
"Go. Please. Live…"
Eren refuses. He claws at the rubble with shaking hands.
"No! Don't leave me! I'm not leaving you!"
Sans grits his teeth, energy building in his palm.
Papyrus reaches for Eren, desperate.
But the Titan grabs her first.
Eren's scream rips through the air.
"NO!"
Sans fires—but too late.
The beam punches through the Titan's chest, but the damage is already done.
Papyrus pulls the kids back, shielding them.
He wishes he could cover their eyes.
Eren collapses, trembling, staring at the empty space where his mother was.
Something inside him snaps.
Mikasa tries to help him stand.
Armin cries into his sleeve.
Papyrus kneels beside them, voice shaking.
"I… I AM SO SORRY."
Sans goes still.
His glowing eye flickers out.
He stares at the smoking Titan corpse, jaw clenched.
Eren finally looks up, face twisted in hatred and grief.
"I'll kill them. Every last one. I'll wipe every Titan off this world."
Sans hears the promise.
And for the first time since they arrived…
He's afraid of a human.
Screen 5 — Stand and Fight
Titans close in from every street.
Walls of flesh, teeth, and hunger.
The evacuation bells keep ringing, but the exits are choking with panic.
Sans steps forward.
His posture shifts.
His eye ignites like a star.
"alright. round two."
Nine small Titans rush toward them.
Sans snaps his fingers.
Gaster Blasters erupt into the air, gigantic skulls with burning jaws.
They open fire.
Massive beams of energy carve through the horde.
Nine Titans drop smoking to the ground in seconds.
Papyrus grabs another child fleeing alone and lifts him onto a wagon headed for the boats.
"PLEASE REMAIN CALM. THE GREAT PAPYRUS IS ESCORTING YOU TO SAFETY."
Sans fires again, blowing another Titan's head apart.
He doesn't joke now.
Every shot is anger.
Armin watches, stunned.
"What… what is he?"
Mikasa stays focused on Eren, holding his hand tight.
"We don't have time to question it."
Eren stares at Sans—at the destruction—and his grief twists into something fierce.
"We need power like that… if we're going to win."
Sans hears him.
For a moment, he looks down at the three kids he just saved.
"just try to stay alive, kid."
More Titans roar from the breach.
Sans Decided go Wall Rose refugee camps Military Training (104th Squad)
