The Art of Ys, Era by Era
Ys never kept one house artist the way some series do, and the result is a gallery rather than a portrait: the painted key art of the PC era, each computer and console port commissioning its own cover painting of the same red-haired swordsman; the Hudson era's anime-inflected art for the CD-ROM games, drawn to match the OVAs the same studio culture was producing; and the modern era's cleaner key visuals, where illustrators like Shunsuke Taue, the artist behind Ys Origin and Ys VI's visual identity, set the look that the Tribute book later borrowed back.
The constant is not a style but a composition: Adol small against an ancient place. Tower, floating continent, lost city, cursed island: the art of Ys is the art of ruins with a traveller in front of them, which is why single covers from any era read instantly as Ys.
