The city was silent.
No cars.
No voices.
No wind.
Just empty buildings stretching endlessly under a gray sky.
A girl walked alone in the middle of the street.
Her name was Airi.
Above her head floated a number.
1
She stopped walking.
Her eyes looked tired… but determined.
"This is it…"
Her voice echoed through the empty city.
Everyone was gone.
Her friends.
Her classmates.
Her family.
Even the boy she liked.
All erased.
One by one.
Because people forgot them.
She looked up at the number again.
1
That meant there was only one person left who still remembered her.
Herself.
Airi closed her eyes.
"I'm sorry…"
Her number slowly flickered.
1
0
The moment it reached zero…
Reality shattered.
The sky cracked like broken glass.
Time collapsed.
And the world reset.
