Advance screenings of Kamen Rider Revice: Battle Familia revealed a Septempremiere date for Geats along with a short story teaser.Ī press conference was held on August 7, 2022, revealing Hideyoshi Kan, Ryuga Sato, Yuna Hoshino, Kazuto Mokudai, Kokoro Aoshima, and former Wizard-star Shugo Oshinari as main cast members, as well as Koda Kumi and Gaim-singers Shonan no Kaze as theme song artists.

On June 26, 2022, the copyright trademark updated to reveal the official title card of the show. Toei Company confirmed and filed the trademark for Geats on May 31, 2022. Takahashi also believed that the original spirit of Kamen Rider was growing weaker, so he created the Rider Core IDs to symbolize the individuality of each character, which does not exist for Riders with more than one transformant. Takahashi noted that when he wrote Kamen Rider Ex-Aid, the types of games he was allowed to include were limited to just racing games and RPGs, but those restrictions had no longer applied when he signed on for Geats. However, rather than having the Riders fight and defeat each other like a battle royale in Kamen Rider Ryuki, Takahashi wanted to tackle more of a game in the sense of Kaiji and the more recently popular Netflix series, Squid Game, where the Riders attempt to save the world instead. However, series head writer Yuya Takahashi believed that the brand's power was also declining as well, so he capitalized on the popularity of having multiple Riders in one series while pitting them in a popular theme of today's standards, such as survival games like Fortnite and Apex Legends to appeal to the new target audience. As each succeeding series premiered, the number of Riders at debut has continuously grown but aren't necessarily stronger than the last. Kamen Rider had grown to a point where everyone in Japan at least knew what it was.
