It was a normal day at U.A. High. Class 1-A was in the middle of Aizawa’s lecture when the air outside began to vibrate. Windows rattled. The sky twisted into colors no one had ever seen before.
“Midoriya, what’s that?!” Uraraka gasped, pointing out the window as lightning spiraled in a circle overhead.
Aizawa frowned, scarf whipping in the rising wind. “Everyone— evacuate now.”
But before anyone could move—
✦ BOOM ✦
A rip in the sky opened, and dozens — no, hundreds — of figures fell through, slamming into the training grounds like meteors.
Scene 2: Impact Zone
Ash and debris clouded the air. When it cleared… chaos had a face.
Illumi Zoldyck stood perfectly still, needles glinting under the sun as Killua yelled, “Bro, WHAT THE HELL— where are we?!”
Hisoka giggled, spinning a playing card between his fingers, eyes twinkling. “Oooh~ new toys.”
Across the field, Luffy shot upright from a crater, rubbing his head. “Owww! Hey Zoro! You alive?”
“Barely,” Zoro groaned, climbing out of another hole 30 feet away. “How the hell did we fall from the sky again?”
“Ceasar, what did you do?!” screeched Monet.
“I— I was just experimenting with— okay, maybe I did open a spatial rift! BUT IT WAS FOR SCIENCE!”
“YOU IDIOT!!” Law snapped, already using Room to move debris off people.
And then—
“Boys and girls!” boomed a voice, deep and almost cheerful. “Seems we’ve stumbled upon a party!”
The ground shook as Kaido landed like a meteor beside Big Mom, both laughing. Whitebeard’s quake power rumbled in response.
Farther off, Shanks whistled low. “This ain’t our ocean anymore…”
Scene 3: The Heroes Arrive
The pro heroes rushed out— Hawks swooping in first, Endeavor’s flames blazing bright, and All Might himself standing tall at the front.
“Listen up!” All Might shouted. “Whoever you are— you’ve invaded U.A. territory! Stand down!”
Mihawk calmly unsheathed Yoru, his eyes gleaming with cold amusement. “Invaded? No. We fell.”
“Yeah,” Doflamingo laughed, strings twitching between his fingers. “But maybe we’ll stay.”
Hawks blinked. “Oh fantastic, another flamboyant psycho.”
Scene 4: More Portals, More Problems
Before anyone could even breathe, another crack opened — this time, dark red and pulsing like a heartbeat.
Out walked the Demon Slayer Corps.
Rengoku landed in a heroic pose. “DEMONS BEWARE!”
Tengen Uzui flexed, grinning. “Now this is flashy!”
Behind them appeared Muzan and the Upper Moons — Doma twirling a fan and grinning like a fool. “Oh? New humans to play with?”
Levi Ackerman dropped down beside Aizawa, slicing through an Upper Moon’s attack before it could touch a student. “You people call this a school?”
L appeared on top of a roof, crouched beside Ryuk, munching an apple. “Statistically speaking, there’s a 99% chance this will end horribly.”
Light Yagami glared up at him, clutching the Death Note. “Maybe it’ll end wonderfully— for me.”
Ryuk chuckled. “Now this is entertainment.”
Scene 5: The Students’ Panic
Mineta screamed as Kuma appeared behind him, expression unreadable.
Bakugo exploded at the sight of Killua’s lightning aura. “OI, SPARKY— you think you’re better than me?!”
Killua smirked. “Pretty sure I am.”
Midoriya was scribbling furiously in his notebook, muttering. “Electric abilities… nen aura… rubber-based physiology—this is insane!!”
Meanwhile, Hisoka had wandered dangerously close to Shinobu, who smiled sweetly. “Would you like a poison sample?”
“Oh, I’d love one,” he purred.
Todoroki sighed. “Why are the hottest people always homicidal?”
Scene 6: The UA Response
Nezu appeared atop a destroyed turret, smiling despite the carnage. “Well, Class 1-A… it seems today’s training exercise just got a bit more advanced.”
“ADVANCED?!” Kaminari yelled. “NEZU WE’RE GONNA DIE!!”
Aang floated in the air with Katara and Zuko, assessing the battlefield. “Maybe we should help calm things down—”
Toph smirked. “Nah. I wanna see who wins first.”
