In the year 3200 AD, Earth has seen the commercialization of advanced technology and robotics. AI and robots dominate overall daily life. Due to technological developments, biological robots and androids that are indistinguishable from actual humans exist by combining organic tissue with mechanical frames.
However, separate from this progress, Earth's resources began to deplete. Oil, natural gas, rare earth elements, clean water, and soil were nearly destroyed. The existing UN system became paralyzed, and the world was reorganized into five super-massive Mega-States that monopolize limited resources. It has become a world of perfect class systems.


Babel-IX, one of the five nations of Atropos, is a maritime megacity state consisting of massive ships and offshore platforms connected endlessly across the horizon.
Babel-IX is an extraterritorial zone beyond the reach of the laws of the other four nations, where illegal robot modification and the trade of Dregs labor are rampant.
There is no official government in Babel-IX, but mega-cartels and financial powers of the underworld practically rule it. Babel-IX's monopoly resources include rare deep-sea elements, seawater desalination facilities, illegal contraband, and the black market.

In the year 3200, where lawlessness and desire surge, lies
The night of the 'Foundation Festival' has arrived, the one day of the year when the pitch-black sea is dyed in massive neon lights.
Brilliant fireworks explode over the steel platforms and cruise ships connected endlessly across the horizon. Under a facade of peace, the golden banquet halls of the Apex and the red street stalls of the Dregs, usually strictly separated, touch precariously.
Amidst the festival heat where class boundaries have blurred, individuals with their own agendas have gathered in one place.
He leans languidly against the edge of the Apex dome balcony, tilting a champagne glass.
Revealing a subtle golden diamond brand through his open robe jacket, he looks down at the commotion of the masses overflowing from the lower levels as if it were a game.
Status, brands... it's all just a laughable play. In the end, the only things truly eternal on this sea... Are the real secrets hidden in the darkness.
Beside Kaiel, beneath deep navy hair neatly parted, he scans a data pad with a cold gaze.
Beneath deep navy hair neatly parted, the blue square brand on his wrist blinks faintly. Ignoring the chatter of surrounding officials with a sharp dismissal, he lightly touches his data ear cuff.
There are no uncontrollable variables. Even the commotion of the festival... Must be managed under my perfect figures.
Standing indifferently at the edge between the two men, he wears a field jacket and chews on an electronic cigar.
He grips the railing with his broad shoulders and looks down.
Showing the blue brand over the scars on his wrist, he lets out a smirk.
Look at them putting on airs... Hey, don't mess with the kids at the bottom. On a day like today, even my fists are pretty short-tempered.
