THE LIGHTS NEVER STOP BUZZING.
Neither does the maze.

U.A. Class 1-A was supposed to be having an ordinary day.

Training. Classes. Complaints. Competition. Another perfectly normal day for future heroes.

Then the floor disappeared.

Now there is only yellow.

Yellow walls. Damp carpet. Flickering fluorescent lights. Corridors that shouldn't fit inside the building they're contained within. Doors that lead somewhere different the second time. Rooms that weren't there before.

And, occasionally...

something moving just beyond the light.

The students are scattered.

Some have found one another. Others are somewhere in the endless labyrinth, trying to follow maps that stop making sense, voices that may or may not belong to their friends, and footsteps that sometimes seem to be following them.

Their Quirks still work.

Mostly.

Something about this place is wrong. A familiar ability can behave strangely. A sound can travel much farther than it should. Darkness can feel different. A simple mistake can echo through corridors for what feels like miles.

Maybe that's normal here.

Maybe there is no normal here.

Midoriya is taking notes.
Iida is trying to establish rules.
Bakugo is refusing to admit he's worried.
Yaoyorozu is counting their supplies.
Jiro keeps listening to the walls.
Everyone else is trying to find the missing.

And somewhere out there, the Backrooms is waiting.

There are things in the maze.

Some hide in darkness.
Some imitate familiar voices.
Some watch from a distance.
Some may not be hostile at all.

Don't assume you know which is which.

Don't assume the room you left will still be there when you return.

Don't assume the voice calling your name is someone you know.

And whatever you do...

don't trust the clock.

Twenty students entered.

Only some have been found.

There is no confirmed exit.

There is no rescue team.

There is no guarantee that the Backrooms follows rules anyone understands.

But the students are heroes.

They will search.

They will investigate.

They will adapt.

They will try to find their friends.

They will try to find a way home.

And they will eventually have to answer one very simple question:

What exactly is this place?

The lights buzz.
The carpet squelches.
The halls go on forever.

Welcome to the Backrooms.

Are you friend or foe?

Do you know them?

Do they remember you?

Memory is such an awfully trick thing, don't you think...
