- Summary: A transaction meeting Gamou was to have with Foundation X goes awry when a mysterious woman named Inga Blink steals replica Horoscopes Switches for space warfare. Telling Hayami and Tatsugami not to pursue, Gamou tells them they will have the Kamen Rider Club deal with her. At Amanogawa High School, Mr. Ohsugi takes Gentaro, Yuki, Kengo, and Ryusei out of computer class and takes them to the Rabbit Hatch to meet up with the rest of Kamen Rider Club. There, they meet a strange lady named Shizuka Shirayama who is a member of OSTO Legacy and requests the Club's assistance. Argeeing to help, the Kamen Rider Club members are taken into a bus and blindfolded for security reasons. But on the way, they are attacked by a robot named Black Knight. Transforming to hold the pursuing Black Knight at bay, Kamen Rider Fourze battles the attacker while Ryusei and the others find themselves boarded by Inga Blink who Ryusei fights while getting her out of the bus. However, Inga destroys the accompanying van to blocks the road while wounding Ryusei with a one-inch punch. When Fourze arrives, warning the Kamen Rider Club not to interfere, Inga summons Black Knight to take her away.
Once at the OSTO Legacy's base and meeting its skating leader Harumi Saeba, the Kamen Rider Club learn that Inga is of the Alicia Federation who created the Space Ironmen like Black Knight and the Kamen Rider Club must go to space to disable their strongest Space Ironman Satellite Weapon XVⅡ. Despite Harumi's insistence that it would be impossible, Gentaro intends to befriend XVⅡ. After hours of astronaut training and combat simulations, despite the injuries Ryusei got from fighting Inga, the Kamen Rider Club are ready to board an Exodus shuttle OSTO Legacy obtained. However, the Kamen Rider Club are ambushed by the replicas of the Horoscopes creates from Horoscopes Switch replicas. As the others race to the shuttle, Kamen Riders Fourze and Meteor battle the Horoscopes and managed to take out most of them. With the shuttle about to launch, Fourze and Meteor get help from a Kamen Rider named Wizard who takes care of the remaining Horoscopes while the Kamen Rider Club head towards space.
Once on XVⅡ, the Kamen Rider Club and Shizuka learn that Inga and Black Knight have stowed away as they fight through both them and the satellite's defense systems to plant explosives in four energy regulators. However, once the mission is accomplished, Ryusei and Tomoko learn too late that Inga is actually a good guy as she reveals that they have been helping the real villains. Reaching the others in at the mainframe of XVⅡ, the Brain Room, Ryusei and Tomoko reveal that Shizuka and Harumi have been playing them. Confirming it as he arrives after she disables XVⅡ's Brain, Harumi and Shizuka hijack XVⅡ and assume their true forms: the Kyodyne Groundyne and Skydyne. Inga reveals that the Kyodyne are Space Ironmen built by her father, Professor Blink, alongside Black Knight. But when the Kyodyne develop independent AI from a surge of Cosmic Energy with the notion that they have been chosen as the dominant life forms, Professor Blink had XVⅡ seal the Kyodyne in human form after being mortally wounded by them. However, to circumvent the set back, the Kyodyne used the Kamen Rider Club to destroy the signal relays that kept them from the Brain Room so they can override the mainframe to take control of the satellite and unlock their full abilities. With them outliving their usefulness, the Kyodyne create Dustards to kill the Kamen Rider Club.
With the others making a run to the ship, with Inga following to protect them after Black Knight sacrificed himself and Ryusei promising to help her, Fourze and Meteor battle the Kyodyne. But the robot siblings prove too powerful for the Kamen Riders as they throw them over the ledge before having XVⅡ assume his robot form to enslave the Earth with a terrorist threat. However, Gentaro and Ryusei learn they are saved by XVⅡ's Brain as he reveals he activate his five-minute self-destruct to stop the Kyodyne. Refusing to have XVⅡ sacrifice himself, Gentaro transforms into Fourze Cosmic States to stop XVⅡ's body from destroying Japan by forcing it through a warp gate that sends it crashing to the moon. However, succeeding in convincing the AI to cancel the self-destruct, Gentaro's gambit damages the Astro Switches as he accepts XVⅡ's friendship before the Kyodyne jump him and Ryusei. Watching, the Kamen Rider Club are powerless until they have an e-mail from XVⅡ containing specs of a new Astroswitch that needs a mass of Cosmic Energy to create. Though the act would be impossible, remembering Gentaro's words that they are a symbol of their friendship, Kengo sends everyone to the school to give an Astroswitch to each person that he befriended at AGHS.
As Meteor takes Gentaro to safety, with the last Astroswitch given to Gamou with everyone thinking of him, the simultaneous activation of all forty causes a chain reaction that produces the Fusion Switch. With Kengo giving him the Fusion Switch, Gentaro uses it and finds himself in a new form with the Meteor Switch: Kamen Rider Fourze Meteor Fusion States. Overwhelmed by Fourze using Meteor's abilities with his own, Kyodyne take battle outside XVⅡ as they assume their vehicle modes with Fourze defeating them on the Powerdizer before finishing the robots off with the Rider Fusion Drill Kick. Once restored, XVⅡ thanks the Kamen Rider Club before leaving to explore the universe to find his place in it. With her mission over, Inga kisses Ryusei and accepting his friendship to Tomoko's dismay.
