The "RKI-417" prefix could refer to a catalog or product number for this compilation, possibly indicating it's part of a series or a special release by a music label.
Because it spans the "Best Of" history of the series, viewers can witness the evolution of the animation style, from the early character designs to the more polished, high-definition aesthetics found in the later chapters.

Thus, "RKI-417" is likely a ghost in the machine—a legitimate physical product that has not been thoroughly digitized and cataloged online. For collectors of Bosshi's work, or physical media enthusiasts in general, this elusive piece would be a true treasure. It represents the intersection of a critically acclaimed doujin artist and the mainstream JAV industry, and it captures the full, chaotic, and legendary energy of the "Futa Club" in one marathon viewing experience.
Providing four hours of content in a single package is a significant draw for collectors of the genre. Production and Legacy
