Miko the Catgirl

Miko is a 21-year-old fictional catgirl character (nekomusume) created within the AI Dungeon community. Originally designed as a template for JSON-based world-building and character memory optimization, Miko represents a digital asset used to improve AI comprehension of physical traits and interpersonal relationships. The character is defined by specific aesthetic markers including amber eyes, brown hair, and feline-type ears and tail.

While Miko originated from user-generated content on the Reddit platform and the Latitude-developed game AI Dungeon, she does not have a traditional corporate manufacturer. Instead, her 'production' occurs through open-source community contributions and digital rendering by LLM (Large Language Model) architectures. She serves as a benchmark for how structured data formats like JSON can be utilized to maintain character consistency in procedural storytelling.
