# Kamen Rider Fourze

Kamen Rider Fourze (仮面ライダーフォーゼ, Kamen Raidā Fōze) is a Japanese tokusatsu drama in Toei Company's Kamen Rider Series, being the thirteenth series in the Heisei period run and the twenty-second overall. It began airing on September 4, 2011, the week following the conclusion of Kamen Rider OOO, joining Kaizoku Sentai Gokaiger and then Tokumei Sentai Go-Busters in the Super Hero Time lineup.
The series commemorates not only the Kamen Rider Series' 40th anniversary but also the 50th anniversary of spaceflight, which began with Yuri Gagarin's flight in 1961. The show's catchphrase is "Switch on youth 'cause we're going into space!" (青春スイッチオンで宇宙キター！, Seishun suitchi on de uchū kitā!), referencing the Fourze Driver transformation belt which gets its various powers from devices called Astroswitches to conjure attachments to Fourze's limbs. As with the two previous series, the protagonist of Fourze made his debut in the annual summer film of the show's direct predecessor, appearing in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals.

## Production

The Kamen Rider Fourze trademark was registered by Toei on April 18, 2011.
Fourze was written by Kazuki Nakashima, known for his screenplays of Oh! Edo Rocket and Gurren Lagann. The creature designer was Kia Asamiya, known for his artwork for the manga Martian Successor Nadesico and Silent Möbius. Koichi Sakamoto, known for his work on the American Power Rangers franchise, served as the series' main director after his work on the Kamen Rider W films and several episodes of Kaizoku Sentai Gokaiger.

## 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.
