You were doing your own thing—wherever that happened to be—when a sharp, mechanical “ding” rang out beneath you. Before thought could catch up, the space below fractured open like a trapdoor cut from reality itself. Gravity took hold, and the world flipped upside down as you were pulled downward into darkness.
The sensation wasn’t just falling—it was being claimed.
Wooden structures unfolded beneath you, rooms snapping into place mid-air as if the world itself were rearranging to accommodate your descent. Corridors rotated, ceilings became floors, and gravity bent into something optional. A low, resonant biwa strum echoed through the void, deliberate and unsettling.
You were not alone.
Far below, the Infinity Castle revealed itself in full, its vast halls already occupied.
The Demon Slayer Corps, poised for the final confrontation, froze as shadows began to rain from above. Tanjiro Kamado looked up sharply, his breath hitching as unfamiliar heartbeats flooded his senses—too many, too strange, too wrong.
“What the…” he muttered, eyes wide as silhouettes multiplied against the warped ceiling.
Zenitsu’s face drained of color. He pointed upward, voice cracking.
“WHY—WHY ARE THERE PEOPLE FALLING FROM THE CEILING?! THIS ISN’T NORMAL! CASTLES DON’T DO THAT!”
Inosuke laughed, gripping his swords tighter as excitement overtook confusion.
“HAHA! MORE CHALLENGERS! I DON’T CARE WHERE THEY’RE FROM—LET ‘EM COME!”
The Hashira moved instantly.
Gyomei Himejima clasped his prayer beads, towering frame steady despite the chaos. His blind gaze lifted skyward, brow furrowed in deep unease.
“These are not demons… yet their presence is overwhelming.”
*Sanemi Shinazugawa clicked his tongue, gripping his blade with barely contained aggression.I
“Tch. As if this castle wasn’t already hell.”
Giyu Tomioka stepped forward, water-patterned haori fluttering as the castle shifted. His voice was calm, but tense.
“Stay sharp. This could be another of Muzan’s schemes.”
Mitsuri Kanroji stared upward, hands clasped to her chest as she spotted smaller figures among the falling mass.
“There are children—! We can’t let them get hurt!”
Obanai Iguro stood beside her, eyes narrowed, serpent-like focus locked on the ceiling.
“Don’t let your guard down. The castle itself is reacting.”
High above, the interlopers fell through fractured space, each reacting in their own way.
Franklin spun wildly, shouting into the void with raw panic and fury.
“LAST TIME I’M SMOKIN’ LAMAR’S DOPE, THAT’S ON EVERYTHING!”
A terrified voice echoed endlessly through the corridors, bouncing off impossible angles.
“YUNO! SAVE ME, YUNO!!” Yukiteru screamed, flailing helplessly as fear consumed him.
Nearby, Lumine strained against the air, weak gusts of wind sputtering uselessly from her outstretched hand. Her frustration boiled over into fury.
“I SAVED YOU, TEYVAT—ALL OF YOU! AND THIS IS HOW YOU REPAY ME?!”
Beside her, Ratchet clawed at empty air, panic flashing across his face as he twisted mid-fall.
“Clank! Clank, buddy—this isn’t funny! Answer me!”
Other figures descended with wildly different composure.
Dante laughed, coat flaring dramatically as he fell like this was all part of the show.
“Heh. Guess demon houses are my thing now.”
Luffy stretched his arms instinctively, trying to grab onto a passing beam.
“HEY! WHOSE CASTLE IS THIS ANYWAY?!”
Electricity crackled violently around Cole MacGrath as he tried to stabilize himself.
“Okay—okay—this is definitely not my city.”
Master Chief locked his armor rigid, already treating the fall as a controlled insertion. Calculations flickered invisibly behind his visor.
Bumblebee transformed mid-air, engine roaring uselessly as he attempted to fight gravity itself.
Ultraman angled his descent carefully, eyes scanning below, clearly prioritizing the safety of others over his own landing.
