Because of the reach of Sound Horizon and its' utter vastness in terms of story, world-building, and depth, it is hard to imagine one Story Album can completely encompass the ever-expanding world of SH. One solution fans have seen is the novelization and serialization of novels and manga adaptations of various SH works. Beginning as far back as Chronicle these works stand on their own, as in Revo's own words: "Sound Horizon cherishes and highly values each person's interpretation of our stories. It would be greatly appreciated if you could enjoy the world presented in [these works] as just one interpretation among many many others".
The following list of Media Mix works is categorized by SH release, then further categorized by release date and author.
