Welcome to the early alpha demonstration of Project Isekai—an upcoming urban fantasy / isekai story game built to push the boundaries of dynamic AI narrative design.

🛠️ About This Tech Demo

This demo isn't just a teaser for the story—it is a live technology demonstration of RagNext, a novel authoring and story design framework built with C# and modern UI architecture.

What RagNext Powers Behind the Scenes:

  • Dynamic AI Storytelling: Blending local LLMs (via Ollama/LM Studio) and cloud APIs to drive dynamic dialogue, real-time choices, and adaptive story nodes.
  • Smart Narrative Graphing: Seamless visual-novel state management that tracks player stats (Strength, Mind, Instinct) and branches the storyline contextually.
  • Procedural Media Pipeline: Automated integration of custom neural audio generation (featuring Azure Dragon HD voices) and styled artwork directly into the narrative workflow.

🌧️ Story Synopsis

An ordinary walk back to the office on a rainy evening takes a terrifying turn when a shrouded stranger accosts you in a dark alleyway. He knows your name, he knows the mysterious encrypted USB drive in your pocket, and he knows that what happens next will shatter your reality forever.

Will you fight, analyze the threat, or follow your gut when the portal opens?
