Final Product: The Fifth Child — Neon Genesis Evangelion AVG





The Fifth Child is a playable AI visual novel set inside the Neon Genesis Evangelion world. You are Shinji Ikari in Tokyo-3, 2015 — after another Angel falls, NERV introduces the Fifth Child, and a boy who has only ever run from closeness must decide what he wants to be.
Every line is written live by an AI storyteller. Every reply nudges three meters — Connection, Duty, and Isolation — and every meter pulls you toward one of three endings: Open Heart, Obedient Pilot, or I Must Run Away. From the apartment after the sirens to a confession by dark water, no two playthroughs of Tokyo-3 are the same.

Game Features
- Live LLM Narrative — Every scene, every reply, and every character — Shinji, Kaworu, Misato — is written in real time by an LLM as you play. No two nights in Tokyo-3 unfold the same (deepseek-chat real-time narrative).
- Three Meters, One Heart — Connection, Duty and Isolation tick with every word you speak. The ending is not fixed: Open Heart, Obedient Pilot, or I Must Run Away — built from the person you decide to be.
- Free-Form Dialogue — Type anything: reach for Kaworu, answer as a pilot, put the silence back on. The AI reads your intent and responds in character, never breaking the world.
- The Fifth Child Cast — Shinji, Kaworu and Misato appear with original cel-shaded sprites (transparent cutouts) over NERV-style scene backgrounds — apartment, GeoFront corridor, rooftop, Eva cage, moonlit lake.
- Milestone Story Beats — The night-and-days arc advances through real milestones: the apartment after the sirens, meeting the Fifth Child, music on the rooftop, Misato's warning, Pattern Blue in the cage, and a confession by the dark water.
- Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every turn.
Character Sprites
Production Process Breakdown
AI receives the prompt "Create a Neon Genesis Evangelion world with the Angel War, NERV, and the Human Instrumentality Project" and generates the world — 19 atom cards: 6 characters, 4 locations, 3 events, 2 factions, and 4 core lore entries. Each card carries original descriptions, cover art, and interconnections.
AI designs the game from the atom cards: writes the story rules around Kaworu Nagisa's arrival, designs the scene flow from the apartment to the moonlit lake, and generates all art — the title key art, five scene backgrounds, and three full-body character sprites. Each sprite was generated on a pure white background, then background-removed to a transparent PNG via BiRefNet.
Game built and published with one click, instantly shareable online. A live LLM (deepseek-chat) improvises every line of dialogue in each character's voice — Shinji, Kaworu, and Misato — as you play, steering Connection, Duty and Isolation toward one of three endings.
Scene Backgrounds






Asset Prompts
"Create a visual novel title screen key art for Neon Genesis Evangelion inspired AVG. Scene: night Tokyo-3 fortress city skyline with retractable armored blocks, distant Evangelion silhouette against blood-orange emergency floodlights and cold blue moonlight, melancholic apocalyptic atmosphere, empty streets, geometric skyscrapers. Style: cel shading, sharp shadows, flat color, 1990s anime theatrical poster, high detail environment, cinematic wide composition with dark lower third for title text space. No text, no logo, no watermark, no UI."
"Full-body visual novel character sprite source image for AVG runtime. One teenage boy standing upright in natural neutral pose, entire body visible from head to shoes, centered with generous margin. Shinji Ikari inspired: 14 years old, short brown hair, anxious gentle face, blue middle-school uniform with white shirt, slim build. Plain pure white matte background (#ffffff) for clean cutout; no scenery, no interior, no exterior, no decorative backdrop, no gradient, no shadowy environment, no checkerboard. Style: cel shading, sharp shadows, flat color, 1990s anime character art. No text, logo, watermark, frame, card border, or UI."
"Create a clean visual novel scene background. Underground NERV headquarters corridor in the GeoFront, industrial metal walls, hazard stripes, cold cyan monitor glow, orange warning lights, long perspective hallway, sterile military science facility, oppressive scale. Style: cel shading, sharp shadows, flat color, 1990s anime background art, empty of people, no characters, no text, no UI, no watermark."
"Create a clean visual novel scene background. Quiet lakeside outside Tokyo-3 at night, still black water reflecting moon, distant fortress city glow on horizon, lonely romantic melancholy, sparse grass and path, cinematic night atmosphere. Style: cel shading, sharp shadows, flat color, 1990s anime background art, empty of people, no characters, no text, no UI, no watermark."
