tl;dr: We're building a 3D first-person adventure game where an AI companion is the core of the game. Think MiSide https://store.steampowered.com/app/2527500/MiSide/ with LLMs, but truly integrated with gameplay, not just a RP chatbot.

ABOUT US

Here at Spellbrush, we're passionate about making a good anime game.

We also happen to be the world's leading generative AI studio—we're the team behind niji・journey https://nijijourney.com/.

Our mission is simple: use AI to bring characters to life and push the boundaries of narrative-driven games.

WHAT WE’RE BUILDING

We’ve developed an in-house LLM storytelling system that blends AI, story, and gameplay—going far beyond shallow “chat-only” experiences.

The result is an AI companion who cooperates with you in puzzles, remembers across worlds, and changes how each chapter unfolds.

We’re looking for a strong Unity engineer who loves 3D story-driven games. You’ll join our lead Unity dev, who has spent the past 5 years building interactive anime avatars, to grow our working prototype into a full game.
