Atelier Ryza: Ever Darkness & the Secret Hideout is the 21st flagship installment in the prolific crafting RPG franchise developed by Gust. The series is divided up into several sub-series that usually focus on a specific region, theme, cast and even character designer. This entry marks the beginning of a new sub-series that will be themed around "summer memories" and will feature designs by Toridamono. The title launched in Japan on September 26, 2019 for both the PlayStation 4 and Nintendo Switch courtesy of Koei Tecmo. A short while later, Ryza was published internationally on October 29, 2019 on both platforms along with an additional PC port.
