AI Collaborative World Building
Steins;Gate — An Interactive AI World
A complete world of time travel, D-Mails, and world-line divergence, generated by AI from the canon of Steins;Gate — 29 atoms, scene art, character sprites, and an interactive studio. The world is not the end point, but the starting point of all creation.
Akihabara, 2010. In a cramped second-floor apartment above a CRT repair shop, a self-proclaimed mad scientist and his friends turn a microwave and a phone into a time machine. Every text message they send into the past — every D-Mail — shifts the world line itself: reality rewrites, memories vanish, and the Divergence Meter quietly counts how far the world has drifted.
On the Alpha world line, Mayuri Shiina is doomed to die again and again; on the Beta line, Kurisu Makise falls instead. Between fate and free will lies a single unreachable point: Steins Gate — the world line where both can live. Meanwhile SERN hunts anyone who threatens its monopoly on time.
Visual style: semi-realistic, painterly strokes, game splash art — neon Akihabara nights, CRT glow, and the quiet dread of a timeline that is always watching. Kimi K3 GPT Image 2

+Create More CharactersFrom the cluttered Future Gadget Lab to the neon maze of Akihabara Electric Town, every location is a stage where history can be rewritten — a maid café, a CRT workshop, a rooftop, a European research citadel. Each one carries an emotional stratum that a single D-Mail can rearrange.

Future Gadget Lab — ground zero of unauthorized time travel

Akihabara Electric Town, summer 2010

Radio Kaikan — where the Beta line is pinned in blood
Locations
Future Gadget Lab
A cramped second-floor apartment above the Braun Tube Workshop that becomes ground zero for humanity's unauthorized time experiments.
Locations
Akihabara
Tokyo's Electric Town — otaku paradise of maid cafés, parts shops, and back-alley workshops where culture and conspiracy intertwine.
Locations
Braun Tube Workshop
Yuugo Tennouji's ground-floor CRT specialty shop, front for ordinary life — and sometimes for Rounder operations.
Locations
MayQueen+Nyan²
Popular Akihabara maid café where Mayuri works part-time and Faris reigns as top maid.

Radio Kaikan
Iconic Akihabara building hosting the metal oopa satellite and the rooftop incidents that pin the Beta world line in blood.
Locations
SERN Headquarters
European research titan that secretly perfected weaponized time travel and rules a dystopian 2036 on the Alpha line.
The PhoneWave Awakens
A failed Future Gadget turns bananas into green gel and, impossibly, sends a text into the past — proving world lines can move.
SERN Database Breach
Daru hacks SERN and uncovers the Jellyman's Reports — proof that human time travel already failed catastrophically in secret.
Mayuri's Fixed Death
On the Alpha world line, Mayuri dies no matter what Okabe changes — train accidents, kidnappings, or chance — revealing fate's cruel attractor field.
Undoing the D-Mails
To escape Alpha, the Lab must cancel each selfish D-Mail — restoring lost fathers, careers, and comforts for a harder truth.
Operation Skuld
Okabe's final plan to deceive fate itself — staging Kurisu's death so the world believes the Beta tragedy while both she and Mayuri live.
SERN's Dystopian 2036
In the Alpha future, SERN rules through time-travel monopoly; Suzuha rebels and leaps to 2010 to break their timeline at the root.
World Lines & Time Tech (9)
World Lines
Alpha World Line
Divergence range where SERN obtains time travel, Mayuri's death is fixed, and 2036 becomes a dystopia.
World Lines
Beta World Line
Divergence range where World War III looms, Kurisu dies in 2010, and Mayuri lives — trading one tragedy for another.
World Lines
Steins Gate
The elusive world line where neither Mayuri nor Kurisu is forced to die and SERN never rules the future.
World Lines
Attractor Field
Metaphysical convergence that forces major outcomes — deaths, wars, regimes — to reassert themselves across nearby world lines.
Time Tech
D-Mail
A text message sent to the past via the PhoneWave that can shift the entire world line when it alters a receiver's decisions.
Time Tech
Reading Steiner
Okabe's rare ability to retain memories of previous world lines after a shift that rewrites everyone else.
Time Tech
Divergence Meter
Nixie-tube device that displays how far the current world line has drifted from the reference point, down to six decimal places.
Time Tech
Time Leap Machine
Kurisu and Daru's refinement that sends only the user's memory data minutes or hours into their own past body.
Time Tech
IBN 5100
Vintage 1975 portable computer capable of reading SERN's hidden codepages — key to erasing the Lab from SERN's database.
World Rules
Attractor Field Convergence
Major outcomes — deaths, wars, regimes — reassert themselves across nearby world lines. You cannot simply 'undo' a tragedy; fate will find another way to repeat it.
Reading Steiner
Only Rintaro Okabe retains his memories across a world-line shift. Everyone else is quietly rewritten, remembering a past that never happened.
D-Mail Causality
A text message sent to the past alters the receiver's decisions at the critical moment — and can shift the entire world line.
SERN's Monopoly on Time
Whoever controls time travel controls the future. On the Alpha line SERN rules a dystopian 2036, so the Lab must erase itself from SERN's database.
The Divergence Meter
Six decimal places of Nixie-tube readings track how far reality has drifted from the reference world line — 1.130426 is a number the Lab never forgets.
The Steins Gate Corridor
A single unreachable world line where neither Mayuri nor Kurisu dies and SERN never rules — the goal of Operation Skuld and the only way out of fate.
