Final Product: Null Field Collective
A five-pairs, one-campus Jujutsu Kaisen AU where each of the five "null fields" is hidden — until tonight, when they let you out for the first time.
Null Field Collective is a playable, AI-narrated visual-novel mystery set inside Jujutsu Tech. Jujutsu Tech believes only one null field exists — a guarded asset kept alone. But they are wrong: there are five, each held by a man who will not let go. For the first time in three years you are allowed to step outside, and every stillness on campus is a place you could go.
Wander the courtyard, cafeteria, library and classroom, find each of the five hidden pairs, and choose which secret to pull into the light. The living LLM narrates, remembers your choices and writes new lines as you play — AI enabled, right in your browser.

Game Features
- Live LLM Narrative — Every line, stillness and revelation is written live by the LLM narrator as you play. The deepseek-v4-flash narrator voices the campus, the five keepers and the girl you play — and remembers every choice.
- Five Pairs, One Campus — A distributed top secret: five hidden "null fields", each held by a man who will not let go. Find all five across Courtyard, Cafeteria, Library and Classroom.
- Choice-Driven Exploration — Choose where to go. Each stillness pulls from a different source; the pair you find and the order you meet them changes what you learn.
- NPC Memory & Relationships — Sorcerer keepers Gojo, Nanami, Higuruma, Sukuna and Choso each guard a pair and respond to how you push. Their pasts stay with them.
- The Null Field Premise — You are not the only one. Every "null field" can sense its own kind; that is why they were kept apart — and why tonight changes everything.
- Browser Playable — Runs directly in your browser, no download. Restart, revisit a stillness or replay the night to pull a different secret into the light.

Production Process Breakdown
From a one-line prompt the AI builds the AVG-cases world: a Jujutsu Tech campus with five hidden "null fields", five keepers who will not let go, and a girl finally let out of the dark. The world is a playable distributed secret.
The AI designs the game and generates every asset: the 16:9 cover, the campus scene backgrounds (classroom, cafeteria, library, courtyard, rooftop, training ground) and the full transparent character sprite set.
The game is built and published with one click and is instantly shareable. The live LLM narrates the campus and writes new lines as you play — AI enabled in your browser.
Scene Backgrounds
Real Generation Prompts
"Empty interior establishing shot, no people, no characters. A modern Jujutsu high-school classroom... cinematic photoreal anime key art, no text, no watermark."
"Full-body visual novel character sprite source image for AVG runtime. One character standing upright, entire body visible from head to shoes, centered with generous margin around hair, hands, clothing and feet. Plain pure white matte background (#ffffff) for clean cutout. Cinematic anime-painterly rendering, dramatic lighting, no text, no UI, no frame, no border."
"Cinematic two-person visual novel CG, 16:9. Keep both faces, hair, outfits and colour palettes exactly consistent with the references. Scene: a moonlit traditional Japanese academy courtyard at night, deep indigo and crimson, floating blue-tinged cursed energy... Unbearable tension, held. No text, no logo, no watermark, no frame."
