Story

Amanogawa High School has become the center of strange happenings, and things only get stranger when the bad boy-styled transfer student Gentaro Kisaragi attempts to make friends in his way, reuniting with childhood friend and self-professed space travel otaku Yuki Jojima, all while gaining the ire of loner Kengo Utahoshi. When the campus becomes overrun with monstrous constructs called Zodiarts, Kengo, and Yuki attempt to use the strange devices they have found in the Rabbit Hatch lunar base that they access through a locker in an off-limits part of campus to fight them. However, Gentaro interferes in their plans, in part due to Kengo's body being unable to handle the strains of battle, and uses the devices to transform into Fourze. Upon learning of other heroes called Kamen Riders, Gentaro creates the Kamen Rider Club whose membership includes Yuki, Kengo, the school's queen bee Miu Kazashiro, Miu's jock boyfriend Shun Daimonji, garishly styled social butterfly JK and goth girl Tomoko Nozama. Later joined by Ryusei Sakuta, another transfer student who transforms into Kamen Rider Meteor, and their teacher Mr. Chuta Ohsugi, the Kamen Rider Club and Kamen Rider Fourze learn of the Horoscopes, an evolved group of Zodiarts who have been orchestrating events on the school grounds to build up their ranks. As the battle escalates, the Horoscopes set their motions to the final phase of their master plan before Kengo discovers his true existence. Episodes
