This article is about a/an episode in Kamen Rider Fourze.

Youthful Transformation (青・春・変・身 Sei・Shun・Hen・Shin) is the first episode of Kamen Rider Fourze, introducing the series' setting and the initial main cast following the appearances of Gentaro Kisaragi and Yuki Jojima in Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals and Yuki and Kengo Utahoshi in the finale of OOO. It is the first part of the initial Orion arc.


The new school year begins at Amanogawa High School, and Kengo Utahoshi is detecting strange energies around the school. And things get stranger when yankee-looking Gentaro Kisaragi transfers into the school and decides that he wants to be Kengo's friend.


The new school year begins at Amanogawa High School, as Kengo Utahoshi encounters a strange delinquent who chides him for throwing a girl's love letter into the river. Later, at Ms. Sarina Sonoda's homeroom class while he using a Burgermeal Foodroid to analyze strange energy readings, Kengo encounters the delinquent as he introduces himself to the class as the new transfer student Gentaro Kisaragi. Despite his scary appearance, Gentaro is a nice guy as he recognizes his childhood friend Yuki Jojima, greeting each other with a special handshake, before giving the soaked letter to Kengo with intentions of being Kengo's friend. Refusing to accept Gentaro's offers of friendship, Kengo walks out of class, much to Ms. Sonoda's dismay. Tracking down Kengo, Gentaro arrives at the cafeteria where he meets JK, while making enemies out of the head cheerleader Miu Kazashiro and her boyfriend Shun Daimonji, the captain of the American football team. Gentaro proceeds to defend himself from the football team before he is forced to let himself be Shun's tackle dummy when Yuki is captured. However, a monster appears from out of nowhere and attacks the group.

The football team runs for it as Gentaro fights the monster, but he is seemingly knocked out. Kengo arrives to even the odds in the Powerdizer exo-suit, and Yuki identifies the monster as the Orion Zodiarts. Physically strained from using the suit, Kengo is unable to pursue the escaping monster. After putting the Powerdizer away, Kengo and Yuki enter a concealed locker that transports them to the Rabbit Hatch lunar base, with Kengo intending to use the Fourze Driver. However, the two discover that they were followed by Gentaro who takes the Fourze Driver instead, while elsewhere the Orion Zodiarts resumes his attack on the school.

With Kengo unable to chase him due to his health, Yuki finds the clueless Gentaro as he faces the Orion Zodiarts and directs him to transform into Fourze. Fourze and the Zodiarts begin fighting in the mens' locker room before Fourze uses the Rocket Module to force the Orion Zodiarts off campus. Gentaro begins to get used to the abilities of Fourze, with Kengo's directions in using the different Astroswitches, before he uses a combination of the Rocket and Drill Switches to initiate the Rocket Drill Kick Limit Break, defeating the Orion Zodiarts. However, the victory falls short when Kengo arrives in the Powerdizer once more with the intent to take the Fourze Driver back from Gentaro by force.

Elsewhere, a mysterious man with red eyes is intruiged that Fourze is in his school as he is joined by a trio of unusual Zodiarts.
