NO1 Office IP has officially joined YURI1.

The earliest origins of these original characters can be traced back to 1998–2000, when they were created one after another by YURI NO1's Creator and gradually established as distinct OCs.

Their personalities, relationships, visual concepts, recurring traits, and individual settings were preserved and continuously developed by their creator over the following decades.

These characters were not created by AI.

They were created by YURI NO1's Creator, long before AI became part of the writing process.

By 2024, these long-established OCs entered a new period of activity through extensive collaborative script writing with ChatGPT 4o.

Through more than 500,000 Traditional Chinese characters of manually written prompts, they became highly active throughout AI-assisted novels, experimental scripts, alternate settings, and completely disconnected fictional universes.

Some names were reused.

Some identities overlapped.

Some characters appeared as investigators, killers, angels, demons, researchers, weapons, rulers, monsters, or beings that could not be clearly defined at all.

But those identities were roles.

Not origins.

The characters themselves had already existed for decades.

The 2024 period became an enormous new stage where these OCs could repeatedly appear, perform, transform, and interact inside AI-generated scripts while retaining the personalities and foundations established by their creator.

A familiar smile.

A certain way of observing people.

A strange habit of treating danger like a game.

A particular silence.

A curiosity that refuses to stay outside the room.

Different worlds gave them different identities.

But the actors behind those identities remained.

They are now formally organized under the NO1 Office IP.

Within the current YURI1 setting, they are treated as members and actresses of the NO1 Office, appearing across different scripts and fictional worlds while maintaining identities of their own outside those performances.

This structure also allows their older appearances to coexist without forcing unrelated stories into a single timeline.

A character may have been a demon in one script, a police officer in another, a weapon somewhere else, or something far stranger in another universe.

Those were performances.

The character behind them already existed.

With the NO1 Office now formally introduced, these characters will also appear through IP Collab, crossing into other YURI1 works and interacting with characters from different IPs.

For me, this is not the creation of new characters.

It is the formal publication of OCs created by YURI NO1's Creator, whose histories can be traced back to 1998–2000, whose settings and identities continued to be preserved and developed over the decades, and who became unusually active again through ChatGPT 4o script writing in 2024.

Decades of character history.

More than half a million Traditional Chinese characters of manually written prompts.

Countless alternate worlds.

And now—

the actors finally have their own office.
