ECHO is a dialogue-based AI platform in which fans interact with AI representations of artists, philosophers, and thinkers. Each dialogue generates Hikari (光貨) — a virtue-based value unit — and a royalty payment flows automatically to the original creator. This paper presents the complete business model architecture of ECHO: revenue mechanics, royalty distribution system, market positioning, scalability design, and philosophical foundation. ECHO represents the first practical implementation of the Hikari Currency (光貨) economic model, transforming human emotional expression into measurable economic value.
