## Story

In Zawame City (沢芽市, Zawame-shi), a large company known as the Yggdrasill Corporation transformed the once-bustling suburb a city into a jōkamachi. To escape the resulting feeling of oppression, many of the youth in Zawame formed dance crews called Beat Riders to bring joy back into people's lives. Also rising in popularity is the Inves Game, a simulator that uses strange devices known as Lockseeds to summon monsters known as Inves. Kota Kazuraba, a member of the dance group Team Gaim, tries to find his place in the world while torn between his loyalty to his teammates and his sister Akira's insistence that he starts acting like an adult and finds a proper job. When Team Gaim's captain disappears after informing Kota of a strange belt he found, Kota discovers that the Lockseeds and Inves are from an alternate dimension known as Helheim Forest. Encountering a mysterious girl resembling his Team Gaim teammate and close friend Mai Takatsukasa, Kota uses a Sengoku Driver belt and the Orange Lockseed to become a samurai-armored warrior that is later named Armored Rider Gaim. In the meantime, including Team Baron's leader Kaito Kumon as Armored Rider Baron and Kota's Team Gaim teammate Mitsuzane Kureshima as Ryugen, other Armored Riders appear to amass social power throughout Zawame: Team Raid Wild's Ryoji Hase as Kurokage, Team Invitto's Hideyasu Jonouchi as Gridon, and the perfectionist ex-soldier Oren Pierre Alfonso as Bravo. Unbeknownst to the Armored Riders, the Yggdrasill Corporation monitors them and the Inves Games while the head of its R&D division, Mitsuzane's older brother Takatora, is the enigmatic white Armored Rider Zangetsu who is protecting a dark secret hidden within Helheim Forest.
Eventually, when Kota confronts Takatora as he becomes a New Generation Armored Rider alongside the Armored Rider development scientist Ryoma Sengoku as Duke, his aide Yoko Minato as Marika, and the Lockseed Dealer Sid as Sigurd, he learns the horrible truth of Helheim Forest: that it was home to a once-prosperous civilization that was eradicated by the strange plants growing throughout it, as anyone who consumed the fruit of these plants is turned into an Inves. Finding an ally in DJ Sagara, a pirate radio DJ who knows more than he is letting on such as the intelligent Overlord Inves, Kota finds himself in the middle of a Sengoku period-like brawl among various factions for the right to possess the power of Helheim Forest–the proverbial forbidden fruit itself–and the fate of life on Earth as he knows it. But while adamant to obtain the Golden Fruit to save the world, Kota notices the disastrous news from Oren and Hideyasu that Kaito transforms into his monstrous form and goes insane. His main objective is to use the fruit's power to shatter the status quo of the world before Kota stops his rampage. After Kota successfully stops Kaito's reign and leaves with Mai to another planet, Mitsuzane and the others face off against Kota's old enemy, Kogane.

## Production and development

Trademarks on Kamen Rider Gaim were requested in May 20, 2013, and the show was officially announced on July 25, 2013. The series producer, Naomi Takebe, wanted Gaim to return to the style of early Heisei era series, in which multiple Riders are featured. Drawing inspiration from the Sengoku period, Bandai presented the idea of using fruits as a core theme to Takebe, which led to the creation of the Arms Change. Takebe approached Gen Urobuchi, known for Puella Magi Madoka Magica and Fate/Zero, to serve as the series main writer, and Ryuta Tasaki, who had previously worked on Kamen Rider Agito and Kamen Rider Ryuki, to direct. In an interview, Urobuchi states that Takebe requested that the series not follow the two-episode structure of recent series, as well as saying that he hopes to create the same kind of excitement he felt from Kamen Rider Black to a new generation. Urobuchi's company Nitroplus also assisted with designs.
The show's lead role went to 2011 Junon Super Boy Contest Grand Prix winner Gaku Sano, portraying Kota Kazuraba. Sano said that he grew up wishing he could be the character from Kamen Rider Kuuga, and now that he would portray Kamen Rider Gaim he hopes that he will inspire a new generation of boys. Rounding out the main cast are Yutaka Kobayashi as Kaito Kumon/Kamen Rider Baron, Mahiro Takasugi as Mitsuzane Kureshima/Kamen Rider Ryugen, Yuumi Shida from idol group Yumemiru Adolescence as the heroine Mai Takatsukasa, and Yuki Kubota as Takatora Kureshima/Kamen Rider Zangetsu.
