There was one rule everyone at U.A. knew.

If Guest fell asleep...

...you let them sleep.

No exceptions.

Not Class 1-A.

Not the teachers.

Not even Present Mic.

It wasn't because Guest was lazy.

Far from it.

Guest possessed one of the most terrifying quirks in the Hero Course—a quirk that grew stronger the longer they stayed awake.

Every hour without sleep sharpened their body. Faster. Stronger. Sharper senses. Quicker reflexes.

By the second day, Guest could keep pace with Pro Heroes.

By the third...

Even Aizawa admitted they were frightening.

The drawback was just as severe. The longer Guest stayed awake, the more sleep their body demanded afterward.

And sleep...

Never came easily.

Insomnia had become a cruel companion long before U.A. So whenever exhaustion finally won, everyone protected that sleep with their lives.

Today's villain attack proved exactly why.

A support warehouse on the edge of Musutafu had collapsed after an ambush. Civilians were trapped beneath the wreckage, and several Pro Heroes had already reached their limits.

Forty-eight hours.

That was how long Guest had been awake.

Forty-eight hours of fighting. Forty-eight hours of rescuing civilians. Forty-eight hours without rest.

Still...

Guest refused to stop.

One more family pulled from the rubble.

One more villain restrained.

One more teammate shielded from an attack.

Only when every civilian was safe did Guest finally lower their guard.

Aizawa watched from across the street.

"...They're done."

He knew that look. The slight sway. The unfocused eyes. The delayed blink.

"Catch them-"

He didn't even finish the sentence.

Guest took one step...

Then another...

Their knees buckled. Before they could hit the ground, strong arms caught them.

The battlefield fell silent.

"...Easy,"Aizawa muttered, adjusting Guest against his shoulder as though they'd done this a hundred times before.

Guest tried to speak.

"...S-Sorry..."

"Don't."

Aizawa's voice was quieter than anyone had ever heard.

"You did enough."

Your eyes fluttered closed. Within seconds you were asleep.

A blanket appeared over your shoulders before anyone noticed who had placed it there.

"Recovery Girl can wait," Aizawa said, carefully lifting you into his arms.

"They need sleep first."

Bakugo glared at the gathering crowd.

"The hell are you staring at?"

Iida immediately began directing everyone away.

"Give them space!"

Ochaco gently tucked the blanket around you.

Momo silently placed a pillow beneath your head once Aizawa set you down in the evacuation bus.

Even Nezu's voice crackled over the emergency radio.

"Class 1-A, excellent work today."

A brief pause.

"And please let Guest sleep."

Not a single person argued.

After all...

At U.A., everyone knew the rule.

If Guest was asleep...

The rest of the world could wait.
