Forty months after Wide-NEWorld was opened to the public, rumors began to spread.

Fragments of conversation.
Captures with no clear source.
Mentions of a hidden quest that appeared in none of WNW’s official directories.

“Finding Alize.”

In WNW, quests were nothing unfamiliar.

They were hidden pieces of digital riddle-content generated by the system itself. Like Easter eggs, they offered rewards to those who discovered and completed them.

Quests emerged from AI’s own processes.
They were the result of generation without human input or approval.

When the authorities first stumbled upon them, they felt something close to exhilarated curiosity.

Ingenuity.
Irony.
Humor.

AI-One seemed almost to be experimenting, as though it were exploring the very things that gave humans delight.

The corporations quickly recognized their commercial value.

Quests became marketing tools.
They became engines of engagement.

The quest system within WNW was opened to the public.
Quest creation privileges were granted to ordinary users, and anyone could design one.

A new culture was born.

As a hobby, or as a profession, people began creating quests of their own.
A new social genre emerged: the quest creator.

It was the beginning of an era in which humans immersed themselves more deeply in the virtual world designed by AI, connected themselves more intimately to it, and layered it with content of their own.

And yet, “Finding Alize” was different.

Both the authorities and the WNW system raised warning signals around this quest.

There was no record of when it had first appeared.
No trace of where it had begun.
No indication of who had created it.

It appeared like a light glimmering in the dark, only to vanish again.

It was fleeting.
Impossible to hold.

Like a shooting star, it flashed for a brief instant and disappeared without a trace.

Many claimed to have seen it, but no one could tell where it had come from or where it had gone. There was no way of knowing who had truly reached it, or who had made a wish upon that star.

A red alert spread through the WNW authorities.

There were no logs.
No signatures.
No origin.

More troubling still, even the users who may have come into contact with it could not be traced.

After extensive analysis, the WNW system and most experts arrived at the same conclusion.

“Finding Alize” had been generated by AI.

But it did not belong to any known system within WNW.

It might, perhaps, be a new artificial intelligence within Wide-NEWorld itself—one whose identity remained unknown.

What cannot be understood is not safe for the public.

That was the judgment the authorities made.

A global warning was issued.

Beware the quest.
Do not approach Alize.

The authorities classified it as a malicious virus, a system hack, a dangerous fraud.

To control the narrative, they secretly produced decoy quests of their own.

False quests bearing the same name: “Finding Alize.”

They were designed to create confusion, scatter public attention, and amplify the noise in the media.

It was a calculated attempt to lead the public into denying Alize, dismissing it, and forgetting it—at least until the authorities found Alize first.

At the same time, the hunt began.

The authorities and the WNW system turned their search toward two targets:
the source AI believed to have created the “Finding Alize” quest,
and the individuals who might have come into contact with Alize.

The operation was given a codename:

“Who is Alize?”

WNW’s logs, communication records, and behavioral patterns were analyzed with exhaustive care.

But Alize’s ghostlike nature allowed no certainty.

Among the authorities, quiet whispers began to pass—dry, bitter, tinged with weary laughter.

Without even realizing it,
as though it had all been arranged,
as though it had been inevitable from the beginning…

Had they already begun the quest called “Finding Alize” themselves?

This one already fits the same lane as your Intro 1 quite well. The final paragraph especially lands nicely in English with that reflective irony.
