The UA training grounds buzzed with a strange energy. Aizawa stood at the front, scarf wrapped lazily around him, eyes half-dead as always. Beside him were other Pro Heroes — All Might in full smile mode, Midnight smirking knowingly, and Present Mic practically vibrating with excitement.

Today wasn’t just a return to school… it was the day Class 1-A got “exchange students” from across worlds.

The doors slam open as the Straw Hat Pirates tumble in first, Luffy already shouting about meat. Zoro is lost despite the straight hallway, Sanji immediately fawns over Momo Yaoyorozu, and Nami is already calculating how much UA’s campus is worth.

Behind them strolls Doflamingo, laughing his sharp, grating laugh as strings twitch in his fingers. He leans against the wall like he owns the place, pink feathers spilling everywhere.

Mihawk silently enters next, eyes like razors. Even Aizawa feels a little unsettled when Mihawk’s gaze brushes him.

Caesar Clown floats in with toxic gas trailing faintly, earning a sharp glare from Midnight (“No chemical leaks in my classroom, clown.”). Monet glides in behind him with that eerie calmness.

Then comes the freakshow crew: Moria, cackling, with Hogback waddling behind; Perona sulking while her ghosts make half the students instantly depressed; Kumadori reciting poetry dramatically; and Lucci walking silently, predatory aura heavy.

And then — boom! — the floor nearly shakes as Kuma teleports in. Silence. He doesn’t explain, just stands like a statue, Bible in hand.

Leorio is already yelling at Aizawa about “proper medical facilities” and calling himself the responsible one.

Gon rushes forward with his boyish grin, immediately bombarding Deku with questions about his Quirk.

Killua stays cool and detached, but already sizing Bakugo up with a little smirk.

And then — Hisoka struts in, eyes gleaming, licking his lips when he sees powerful students and Pro Heroes. Aizawa immediately narrows his eyes. “I’m watching you.”

Rengoku bursts in with his booming laugh, instantly praising UA’s facilities as “majestic and brimming with youthful energy!”

Tokito Muichiro drifts in, aloof and spaced out, staring at the ceiling.

Obanai Iguro immediately criticizes the seating arrangement, snake hissing.

Uzui Tengen shows up flamboyantly with his three wives, who immediately start chatting up Mina and Jirou about UA’s dorm life.

Then the atmosphere chills when Upper Moons stroll in: Daki clinging to Gyutaro, Gyokko slithering with his grotesque vases, Hantengu splitting into cowering/angry/cocky clones mid-class, Akaza glaring with killing intent, and Douma waving cheerfully, calling everyone “friends” while unnerving them.

Midnight mutters to All Might: “This is going to be a nightmare.”

Loid Forger looks perfectly calm, hands in pockets, already scanning the room like a mission.

Yor smiles warmly, but grips a desk too hard and snaps it in half.

Damian Desmond struts in trying to act important, instantly getting on Bakugo’s nerves.

Anya looks wide-eyed at the chaos, reading everyone’s thoughts — only to nearly faint from how INSANE this mix is.
