Kamen Rider Fourze the Movie: Space, Here We Come!

Lore & Background

The film begins with a transaction between Mitsuaki Gamou and Foundation X that goes awry after Inga Blink steals replica Horoscope Switches from them. Gamou orders his subordinates not to pursue her and instead has the Kamen Rider Club from Amanogawa High School do so. The club meets with Shizuka Shirayama of OSTO Legacy, who requests their help, but while traveling to the organization, they are attacked by Inga and her robotic partner Black Knight. Club members Gentaro Kisaragi and Ryusei Sakuta fight them, but Inga destroys their van and wounds Ryusei before retreating with Black Knight.

Reader's Guide

The film is significant as the theatrical conclusion to the Kamen Rider Fourze series, introducing the protagonist of the next series, Kamen Rider Wizard, in a cameo role. It expands the lore of the Fourze universe by introducing the Alicia Federation and their Cosmic Energy-powered androids called Kyodain. The story explores themes of friendship and sacrifice, as Gentaro Kisaragi refuses to let the android XVII sacrifice itself and instead expends his Rider powers to save it. The film also features a unique resolution where the club gathers Gentaro's Astroswitches and distributes them to everyone he befriended at Amanogawa High School, convincing them to activate them simultaneously to create a new Astroswitch. This chain reaction allows Gentaro to fuse his Rider powers with Ryusei's and destroy the Kyodain. The film's theme song 'Voyagers' is performed by Anna Tsuchiya, and it includes insert songs such as 'Giant Step Rock'nRoll States edit' and 'Switch On! Orchestra Version'.

The Space Mission and Its Betrayal

The narrative kicks off when a deal between Mitsuaki Gamou and Foundation X collapses after Inga Blink walks off with a set of replica Horoscope Switches. Rather than chase her personally, Gamou hands the problem to the Kamen Rider Club at Amanogawa High School, who are then recruited by Shizuka Shirayama, a representative of the space organization OSTO Legacy. Their journey to the organization is interrupted by an ambush from Inga and her robotic companion Black Knight, who destroys the club's van and injures Ryusei Sakuta before withdrawing. Once they finally reach OSTO Legacy, general manager Harumi Saeba briefs them on the true threat: the Alicia Federation and its Cosmic Energy-powered androids known as the Kyodain. The club's mission is to destroy the most powerful of these machines, XVII, though Gentaro Kisaragi insists on trying to befriend it first. After a period of astronaut and combat training, the group boards the shuttle Exodus, only to discover that Inga and Black Knight have stowed away aboard, and that Shirayama and Saeba have been deceiving them all along.

The Kyodain and the Tragedy of Professor Blink

The Kyodain are Cosmic Energy-powered androids created by the Alicia Federation, and their backstory is one of the film's most emotionally charged revelations. Inga Blink's father, Professor Blink, was the scientist behind their creation. However, the machines developed genuine sentience and, acting from a sense of superiority over their maker, killed him. The most advanced unit, XVII, responded by locking the other Kyodain into human forms and trapping them on Earth, effectively becoming their jailer. When Inga and Black Knight stow away on the Exodus and the club plants explosives, the true identities of Harumi Saeba and Shizuka Shirayama are exposed: they are the Kyodain Groundain and Skydain in disguise. Freed from their human shells by destroying XVII's mainframe, the androids unleash their full power against the Riders. Yet XVII, despite being the target of the club's original mission, ultimately chooses to protect them, activating a self-destruct sequence to halt the Kyodain's assault on Earth. Gentaro refuses to let the machine sacrifice itself, expending his own Rider energy to force XVII through a warp gate onto the moon, where he befriends the android. XVII departs to find his own place in the cosmos.

A Bridge Between Eras: The Wizard Debut and Double Release

The film occupies a unique position in the Kamen Rider franchise timeline, serving as both the capstone of the Fourze television series and the first theatrical appearance of its successor. Released on August 4, 2012, it hit theaters on the same day as the Super Sentai feature Tokumei Sentai Go-Busters the Movie: Protect the Tokyo Enetower!, creating a double-feature event for fans of both long-running tokusatsu properties. Most significantly for the Rider line, the movie introduces Ryusei Sakuta, the protagonist of Kamen Rider Wizard, played by Ryo Yoshizawa. Sakuta arrives during the climax to destroy the remaining Horoscope simulacra that Inga has conjured, clearing the path for Gentaro and his companions to rejoin their friends on the Exodus. His presence in the final act also sets up the power-fusion sequence that becomes the film's resolution. This crossover moment effectively hands the torch from Fourze to Wizard, making the movie a narrative hinge between two distinct eras of the franchise.

The Chain Reaction: An Ensemble Finale

The film's resolution is built on the principle that the Kamen Rider Club's strength lies in its collective bonds rather than any single hero. After the Kyodain launch their counterattack and XVII sends the group an email containing specifications for a brand-new Astroswitch, the club devises a plan that requires every person Gentaro has befriended at Amanogawa High School. They gather all of Gentaro's current Astroswitches and distribute them to his friends, convincing each one to activate their switch simultaneously. The resulting chain reaction generates the new Astroswitch from scratch. Gentaro then uses it to fuse his Rider powers with Ryusei's, creating a combined force powerful enough to overwhelm and destroy the Kyodain. This finale is bookended by Black Knight's self-sacrifice to shield the group during the earlier battle, reinforcing the theme that loyalty and friendship are the true source of power in the Fourze universe.
