The Origin Story: How Kuroryuu Was Born

storybehind-the-scenesannouncement

It Started With a Plan

In 2023, I found out my wife was pregnant. That's when I started building.

Not just a game. A plan. A way out.

Marlee Rose was born June 19, 2024. She's the reason for every line of code, every late night, every decision documented here. This was never about building tech for tech's sake.

The 3-Year Preparation (2023-2025)

What most people saw: a guy learning Unreal Engine 5, posting game dev content on YouTube, shipping some marketplace assets.

What was actually happening:

  • 877 ChatGPT conversations documenting every design decision
  • 27,570 messages indexed into a searchable knowledge base
  • Reusable assets built for the FAB Marketplace that would fund development
  • A dragon companion named Kuroryuu Genmu (Black Dragon of Illusory Fog) designed across dozens of conversations
  • A plan for the day when AI would be capable enough to accelerate everything

I wasn't learning. I was prepping the battlefield.

October 2025: The Turning Point

Claude Opus dropped. At this point, I had never used a CLI before. Never touched terminal-based AI tools. But I had 3 years of accumulated knowledge waiting to be deployed.

4 months later, I had built two orchestration platforms.

The 4-Month Sprint

From October 2025 to February 2026, everything came together:

Kuroryuu — the AI orchestration platform you're reading about right now. MCP gateway, Electron desktop app, multi-agent teams, graph visualization, TTS, memory systems, and a full persistence layer with checkpoints and worklogs.

Shadows and Shurikens — a pure stealth game in Unreal Engine 5 with 27 modular plugins, a smoke dragon companion, and diegetic UI. The game that started it all. Website live at shadowsandshurikens.com.

FAB Marketplace Assets — Dragon Scribe Elements, Grunge GUI, Samurai Helmets, Ancient Game Maps, Swords and Katanas. The same assets styling both the game and the Kuroryuu desktop app.

The Ecosystem

Everything feeds everything else:

| Layer | What It Does | |-------|-------------| | FAB Marketplace Assets | Passive income + visual identity for everything | | Shadows and Shurikens | The game, using the same dragon and assets | | Kuroryuu Desktop App | Documents and orchestrates the development | | YouTube Channel (5K subs) | Opens doors and builds community | | Hackathon Submission | Potential viral moment |

The Dragon Scribe PNGs selling on FAB are the same PNGs styling Kuroryuu's imperial theme. One vision across every product.

The Hardware

You can't build two platforms on a potato:

| Component | Spec | |-----------|------| | CPU | AMD Ryzen 9 9950X3D (16 cores, 32 threads) | | RAM | 64GB | | GPU | NVIDIA RTX 5090 (32GB VRAM) | | Local LLM | Devstral Small 2 (24B) + Gemma 3 4B |

Running local inference alongside Claude API calls. 15 parallel analysis agents barely touched 7% CPU.

The Truth

A father who never used a CLI built two AI orchestration platforms in 4 months because 3 years ago, when he found out he was going to be a dad, he started planning.

Win or lose, Marlee Rose will one day know that her dad bet everything on himself when she was born — and he didn't stop until he built something real.

The dragon is real.
