Kamen Rider Fourze (仮面ライダーフォーゼ, Kamen Raidā Fōze) is a Japanese tokusatsu drama and the 22nd entry in the Kamen Rider series written by Kazuki Nakashima. Transfer student Gentaro Kisaragi transforms into the titular hero Kamen Rider Fourze to battle the constellation-themed monsters called Zodiarts. Series' producer Hideaki Tsukuda initially planned on including various past Kamen Riders in the series to commemorate Kamen Rider's 40th anniversary. However, due to past series Kamen Rider Decade celebrating the 10th anniversary of the Heisei Kamen Riders, Kamen Rider Fourze appreciates the previous Kamen Riders' history and treats them as urban legends in-universe.
