Final Product: Final Selection: Night of Wisteria
Final Selection: Night of Wisteria drops you onto Mount Fujikasane in Taisho-era Japan — seven nights, one mountain, and demons bound by wisteria waiting in the dark. You are a Water Breathing candidate. Pass the trial, and the Demon Slayer Corps accepts you. Fail, and the mountain keeps you.
Cross paths with Tanjiro Kamado, who carries his demon sister Nezuko in a wooden box, with Zenitsu Agatsuma, who sleeps his way to lightning, and with Inosuke Hashibira, who wears a boar's head and fights on instinct. Every scene, every reply, every choice is written in real time as you play — no two nights on the mountain are ever the same.

Game Features
- Live LLM Narrative — Every scene, every reply, and every character — Tanjiro, Zenitsu, Inosuke, and the demons of the mountain — is written in real time by an LLM as you play. No two runs of the Final Selection unfold the same (deepseek-chat real-time narrative).
- Seven Nights, One Trial — A seven-day gauntlet on wisteria-bound Mount Fujikasane. Manage your breath, your blade, and your nerve from dusk to dawn — and survive long enough to earn your place among the Demon Slayer Corps.
- Choice-Driven Survival — Ask Tanjiro what he knows about the mountain, step into the trees alone, or listen for sobs among the other candidates. Every choice sends the story down a different path — and the LLM remembers what you did.
- Water Breathing & Nichirin Steel — A blade that drinks the sun and a style that flows like current and tide. Learn the forms, read the flow of battle, and cut down demons before they cut down you.
- Real Demon Slayer Cast — Tanjiro and Nezuko, Zenitsu the lightning coward, Inosuke the boar-masked brawler — each rendered as a full-body sprite with multiple expressions, brought to life scene by scene.
- Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every page turn, from the first wisteria blossom to the dawn of the seventh day.

Production Process Breakdown
AI receives the prompt "Create a Demon Slayer world with the Demon Slayer Corps, Breathing Styles, and demons" and generates the Demon Slayer world — 28 atom cards: characters (8), locations (6), events (5), rules (7), factions (2). Each card contains original descriptions, cover art, and interconnections.
AI designs the game from atom cards: writes story rules, designs the seven-night scene flow, generates all art assets (title background + 5 scene backgrounds) and 7 character sprites. Each sprite was generated with a full-body sprite prompt, then background-removed to transparent PNG via BiRefNet.
Game built and published with one click, instantly shareable online. A live LLM (deepseek-chat) improvises dialogue in each character's voice — Tanjiro, Zenitsu, Inosuke, and the demons of the mountain — as you play.
