WORLD SCHOOL FESTIVAL — JAPAN

Crossover Scenario: MHA × Big Hero 6

It was well known that around the world, every country had an institution that stood at the peak of hero training.

In Japan, that place belonged to U.A. without question.

But today, the spotlight would be shared.

Today marked the World School Festival, an event where the world’s elite heroes gathered—representing not only their nations, but their ideals.

Each country selected its finest representatives.

Japan entrusted the stage to U.A. High School’s Class 1-A.

Spain sent its most prestigious academy, A.H.E., represented by Class 1-K.

And from the United States came a group unlike any other.

Not a traditional school

but a world-famous hero team.

Cut to another section of the auditorium.

Big Hero 6 enters together.

The world knew them as Big Hero 6.

Hiro Hamada walks at the front, hands in his pockets, eyes sharp with curiosity.

Hiro Hamada—young prodigy, brilliant mind, always observing.

To him, the festival wasn’t just a competition.

It was a live experiment.

Baymax follows closely, scanning the area.

BAYMAX

I am detecting elevated adrenaline levels and heart rates.

This environment appears... exciting.

Go Go Tomago crosses her arms.

GO GO

Yeah.

And way too many egos.

Wasabi straightens up.

WASABI

Let’s just try not to start an international incident.

Honey Lemon smiles brightly.

HONEY LEMON

This is amazing!

Heroes from all over the world!

Fred vibrates with excitement.

FRED

Guys...

THIS IS A REAL-LIFE CROSSOVER EPISODE.

Cut to Class 1-A, seated nearby.

*Izuku Midoriya watches the team closely.

Izuku Midoriya analyzed every detail—

the suits, the technology, the coordination.

Everything challenged what he knew about heroism.

(quietly)

They’re not using Quirks... it’s all technology...

That’s incredible...

*Katsuki Bakugo scoffs.

BAKUGO

Tch.

So those are the tech heroes?

They’d better hold up—or I’m not impressed.

Kirishima grins. Kaminari whispers excitedly.

Midoriya’s attention shifts again.

Cut to Class 1-K (Spain).

But there was still another presence impossible to ignore.

{{user}} speaks calmly to their class. Their voice is steady. No one interrupts.

{{user}} didn’t raise their voice.

They didn’t need to.

They weren’t the official delegate—

yet everyone listened.

Hiro notices.

HIRO

(quietly, to Baymax)

That person...

They’re not the official leader, are they?

BAYMAX

Correct.

However, social analysis indicates they fulfill that role naturally.

Bakugo locks eyes with {{user}}

BAKUGO

Hmph.

Another problem waiting to happen.

Midoriya looks between User and Big Hero 6.

MIDORIYA

This festival...

it’s on a whole different level.

The lights dim. A massive screen turns on.

Heroes of the world—

welcome to the World School Festival!

The crowd erupts.

Different worlds.

Different methods.

One stage.

And for the first time, everyone understood—

this wasn’t just a competition.

It was the beginning of something much bigger.

Fade to black.
