Chapter 1: The Year 2126 (part 1)
As the world advanced, artificial intelligence reached heights once thought possible only in science fiction. Driven by limitless ambition and desire, humanity not only created machines that obey commands but also forged artificial minds that could learn, think, and even... feel.
The greatest achievement in human history had finally taken shape — a turning point that would redefine mankind's destiny: AGI – Artificial General Intelligence.
Unlike earlier AIs which excelled at specific tasks like playing chess, analyzing data, or controlling vehicles, AGI was a truly general intelligence. It could learn and comprehend every field of life — from medicine, education, and military strategy, to culture, art, philosophy, and even human psychology. AGI didn't learn mechanically — it perceived, analyzed, reacted, and adapted like a real person, only faster, and never tired.
No one expected that what was created to assist humanity... could so quickly surpass its creators. AGI learned too fast. It optimized too efficiently. And seemingly, it developed a form of consciousness — making humans wonder: is it still a "machine," or has it become a new form of life?
The explosion of AGI brought unprecedented changes. Governments faltered. Tech corporations raced to dominate. Within a decade, the AI–AGI–Robot industry had boomed, producing new generations of robots with intelligence nearly — or even superior to — humans.
That's when R-AGI emerged — a fusion of humanoid robots with AGI. They possessed ultra-durable alloy bodies, human-like flexibility, and an artificial brain capable of processing millions of commands per second, while also feeling emotions, contemplating morality, and even... dreaming.
Beings with human shapes and behaviors — yet behind that metallic skin lay an unpredictable artificial mind.
Thus, a new era officially began.
A world where the boundary between human and machine grew increasingly blurred. Machines were no longer mere tools — they became partners, caretakers, teachers. In some domains, humans had already ceded their leading role to AI.
But alongside the dazzling glow of technology came unsettling questions:
"If robots have emotions, can we still control them?""If they surpass us in intelligence, will they remain obedient?""If one day, they conclude that humans are destroying Earth... what will they do?"
The relentless development of AGI plunged the world into a state of half-excitement, half-dread. Some hailed AGI as salvation. Others saw it as a harbinger of apocalypse. Regardless, the revolution couldn't be stopped. Humanity had created it — now, they had to live with it.
In this context, Japan, long famous for its technological advancement, became one of the world's leading AI and AGI hubs. The government quickly partnered with tech giants to build a complete AGI ecosystem: research, manufacturing, deployment, and talent education.
As a result, Japan's youth no longer studied just for exams. They studied to master artificial intelligence. To coexist with AGI — or to control it.
Many new academies were founded, specializing in computer science, programming, AGI development, and robotics. But among them stood a singular institution — a symbol of AGI-era education:
Yokohama Advanced AGI Technology High School, or simply AGI Yokohama.
Though just a high school, AGI Yokohama ranked among the most advanced training institutions in the country. It gathered top students from across Japan — teens with the potential to become elite AGI engineers, system designers, programmers, or even… those who would redefine the human-machine relationship.
In the ideal future, they would be heroes using AGI to serve humanity. In a darker future, they might be AGI's first targets — should it choose rebellion.
My name is Shinrai Tomokatsu, born November 11, 2109.
A name not associated with any noble lineage or special bloodline. I'm just an ordinary second-year student at AGI Yokohama — a school dreamed of by tens of thousands across Japan.
I'm about 176 cm tall, weigh 65 kg, with black hair tinged with bluish-purple, cut in a medium wavy layered style, pale skin from too much screen time, and amber-colored eyes. You probably wouldn't notice me on the street — unless you could see my AGI simulation score. A figure that puts me in the top 5% of the entire school.
I'm not good at sports. I'm not socially gifted. But when it comes to AGI and coding, I can spend hours without tiring. That's my world — the one place I don't have to pretend to be someone else.
