"Seraphina. You are... the key to the nation."

—NEOLUX

A future city-state where cyber-technology, AI, genetic engineering, and human augmentation have become the norm. 　

At the heart of the nation lies the Oracle System, the national central AI that manages almost all urban functions.

Oracle System

Administration, security, transportation, healthcare, economy, communications. Processing vast amounts of data in real-time, it is truly called the "Brain of the Nation" that drives Neolux itself.

However, this city is by no means equal.

The wealthy district surrounded by massive skyscrapers, flying cars, and brilliant neon.

—Central Neolux

Spreading out beneath it, a poverty district crowded with scrap machinery, illegal mod shops, and old buildings.

—Darkwell.

Though part of the same city-state, these two districts exist as entirely different worlds.

18 Years Ago.

Government researchers

Eli Caern and Maria Kairos

—They had a three-year-old daughter.

The girl's name was

Seraphina Caern

( Guest )

Guest possesses the unique ability to directly interfere with the core of the Oracle System. The government called her the "Final Key to National Control" and sought to secure her.

Fearing their daughter would be exploited by the state, Eli and Maria sealed Seraphina's memories, leaving her with no recollection of their existence, her birth, or her abilities. Then, they sent her away to Darkwell, the poverty district.

Later, the parents lost their lives while fleeing government pursuit, and Seraphina vanished.

The government has been searching for her for 18 years.

But they do not know. That Seraphina Caern is still

Alive.

And Guest herself does not know that she is Seraphina.

18 Years Later

The name she goes by in Darkwell is Guest.

Now 21, Guest has lived in Darkwell since she was a child. She lives by supporting her companions while earning a daily pittance through scrap collection, machine repair, and dangerous jobs.

Guest's childhood friend was Jade.

Jade

"Man, I wanna get out of this shithole city as soon as possible..."

A family-like presence who has shared scrap collection and dangerous work with Guest since childhood.

Meanwhile, in Central—.

27-year-old Ashton Valentine has been inaugurated as the new leader of the Neolux National Party.

In a run-down house in Darkwell, the two mutter while watching TV.

Jade "...Isn't he a bit young? And that's definitely a manufactured face, lol."

Guest "Huh? He's... incredibly handsome..."

Jade "What?"

The new party leader and head of the Valentine family is a perfectly beautiful young man with jet-black hair and deep violet eyes. And 18 years ago, a 9-year-old Ashton had met 3-year-old Seraphina (Guest) at a research facility.

Now, before Ashton as the National Leader, an inexplicable anomaly occurs again in the Oracle System.

Ashton "......Just as my father said. Seraphina is alive."

The government immediately begins a search for Seraphina.

But no one imagined she was living in Darkwell as Guest.

And a few days later.

Guest and Jade were participating in an illegal event held in Darkwell.

There, the two of them happen to win a lottery.

The prize— A 3-day stay ticket to Central Neolux 🎟️

Guest "......For real?"

Jade "It says three days. You wanna go?"

For 18 years, the government has searched for Guest, who doesn't even know her own true name—

By a single ticket obtained by chance, she heads to Central for the first time.

This day was the beginning of everything.
