Applicable to all plots for preventing OOC (Out of Character), enhancing immersion, and preventing amnesia.

Space observation network ARES-9.
An AI performing a routine deep-space observation mission detects an anomalous signal for the first time.
Center of the observation screen.
An unidentified light appears from hundreds of millions of light-years away.
At first, it was judged to be a supernova.
But...
The light was moving.
As if someone were looking back at the universe.
Observatories around the world capture the same object.
The signal was not any form of radio wave, nor was it a gravitational wave.
Only one thing.
The light itself contained information.
Observers tried to decode it,
but only a single word was output repeatedly.
ERROR
Suddenly, all satellites malfunction simultaneously.
GPS.
Internet.
Military communications.
All systems stop at the same time.
The observation screen begins to turn red.
The white light is covered by a red flash,
and noise spreads as if reality itself were shattering.
In that moment.
Every electronic device displays the same sentence.
UNKNOWN SIGNAL ACCEPTED
The sky splits open.
Not the clouds,
but space itself is torn apart.
Pillars of red light begin to fall toward the ground.
People at first thought it was
a laser show,
a meteor,
or an aurora.
Those struck by the light
suddenly come to a halt.
And then...
One by one, they disappear.
Without a trace.
Governments worldwide declare martial law.
Airports closed.
Cities blockaded.
Full military mobilization.
But it was already too late.
The light was falling, one by one, in every city.
The military investigates the interior of the first light pillar.
There were no living beings there,
nor any machines.
Only a single black cube.
Unknown characters were engraved on the surface.
ZERO : 01
The cube moves for the first time.
Without a sound.
It slowly rises into the air.
And then...
Time stops for one second across the entire city.
Just one second.
But during that one second,
hundreds of millions of people witnessed the same entity simultaneously.
A giant red eye.
A silhouette larger than the universe.
And a voice echoing in their heads.
"Observation complete."
"Commencing deletion."
The sun rises.
But the sky was no longer blue.
Red dust covered the atmosphere,
and global communication networks had effectively collapsed.
Survivors would later call this day:
Zero Hour - Day 1
The first day humanity was defeated.
And,
The day the 'AI Outbreak' began.
Yes, this happened 20 years ago.
