In his author comments in the 46th issue of Akita Shoten's Weekly Shōnen Champion magazine on Thursday, Saint Seiya creator Masami Kurumada revealed that he is preparing a project that "will probably surprise everyone."

Kurumada has been serializing Saint Seiya: Next Dimension - The Myth of Hades in Weekly Shōnen Champion since 2006. The most recent season ended in February and he launched a new season in September.

Kurumada published the original Saint Seiya manga from 1986 to 1990. The manga has inspired a number of television anime, OVAs, anime films, and spinoff manga. Netflix announced a new CG anime based on the original manga in August, and the Saint Seiya: Saintia Shō spinoff manga also has an anime in the works. A live-action Hollywood film has also been greenlit.

Viz Media published the original manga in English under the title Saint Seiya: Knights of the Zodiac. Seven Seas Entertainment licensed the Saint Seiya: Saintia Shō manga. ADV Films released Toei Animation's anime adaptation with an English dub under the title Knights of the Zodiac, and later released it unedited under the title Saint Seiya. New Video Group later also released the series on DVD.
