Kota Kazuraba

"This is my stage now!"

- Gaim's pre-battle quotes

Kota Kazuraba (葛葉 紘汰) is one of the main characters and the main protagonist as well as the titular character of the Kamen Rider Series installment, Kamen Rider Gaim. When he accidentally found the Sengoku Driver and a pair of Lockseeds (Orange and Ichigo), he gained the ability to transform into Kamen Rider Gaim (仮面ライダー鎧武 [ガイム]). But by doing so, he was labeled Test Subject 01 by Ryoma Sengoku.

History
When Kota is called by Team Gaim's leader Yuya Sumii, who wants to show him something to help their team out. But finding Yuya no where while finding his old friend and former team mate Mai, Kouta instead finds a portal to a mysterious forest. There, Kota finds a mysterious belt and ends up using it with a freshly ripened Lock Seed to fight an Inves that followed him and Mai to their reality. Learning the belt is a Sengoku Driver that Yuya bought from the mysterious Lock Seed Dealer Sid, using it to destroy the attacking Inves, Kota attempts to figure out a means to best use his new ability. It is only after an Inves Game between him and Team Baron's Kaito Kumon ends badly with his summoned Inves going on a rampage that Kota sees his purpose and transforms into Kamen Rider Gaim to stop the monster. This event spreads across the city, earning Kota the name of "Armored Rider Gaim" as he decides to help Team Gaim as an official member in Yuya's stead. However, Kota finds more five more Armored Riders appearing in Zawame with his Team Gaim team mate Mitsuzane becoming their group's primary Armored Rider Ryugen so he would not focus his life around them. Eventually, learning the Inves' home is called Helheim Forest, Kouta and Mitsuzane learn of that Sid is working with the Yggdrasill Corporation in an experiment involving the Armored Riders. Though the majority of the Yggdrasill Corporation believes his use to them is over, Kota finds himself receiving an Energy Lock Seed and a Genesis Core from DJ Sagara. Later, due to his status as a Beat Rider, he is unable to find a job until the Beat Riders' public reputation restored. Soon after, Kota begins to learn the truth of Helheim Forest and Yggdrasil's goals and intended to stop the latter's agenda. However, Kota is stopped by Takatora who proceeds to break the boy's spirit by revealing that the first Inves he killed was actually Yuya. While he is still trying to figure out what to do with this new information, DJ Sagara approaches him and tells him his new purpose should be in destroying the rules the Yggdrasill Corporation is following in order to change the world for the better, rather than allow them to cull humanity. To achieve this goal, DJ Sagara creates the Kachidoki Lock Seed and gives it to Kota.

Gaim is set to appear with Kachidoki Arms as his final form in the new Battride War.

Personality
Kota is a cheerful person who concerns himself with helping and protecting everyone and due to this, "protecting people" is his very reason in fighting when it comes to his duty as a Armored Rider. This is shown when he rescues the Yggdrasill Corporation scientists from a horde of Elementary Inves despite holding a grudge against them for using the Beat Riders dance crews and their Inves Games as tests and lab rats (this also includes the Armored Riders).

Still learning to live as an adult, his world view is very limited and as such, he is very naïve and can be oblivious to consequences and the price that comes with having great power. He does not have any interest in battling other Riders, or anyone if he can avoid it for the matter and decides that he and other Riders should use their powers to save humanity.

Initially due to his inexperience and naïveté, he foolishly and recklessly used the power of Gaim for his own personal gain such as using it for his part-time jobs (and failed spectacularly to boot) and battling at the Inves Games. As such back then, he regarded himself as nothing more than being lucky to have found the Sengoku Driver and saw the whole thing as little more than a game. But after a short encounter with Zangetsu, Kota felt stressed and traumatized but recovered and realized the price that comes with such power.

Arms
Like his fellow Lockseed-using Armored Riders, Kamen Rider Gaim's forms are called Arms (アームズ). With the exception of Suika Arms, all of his Japanese Samurai, Ninja, and Shogun-themed Arms' helmets share the title Kabuto (カブト), while his visors are called Pulp Eye (パルプアイ).

Portrayal
Kota Kazuraba is portrayed by Gaku Sano (佐野 岳), 2011 Junon Super Boy Contest Grand Prix winner. Sano said that he grew up wishing he could be the character from Kamen Rider Kuuga, and now that he will portray Kamen Rider Gaim which he hopes that he will inspire a new generation of boys.

As Kamen Rider Gaim, his suit actor is Seiji Takaiwa (高岩 成二), who has been the suit actor for the majority of leading Heisei Kamen Riders (except Kuuga and Hibiki).

Behind the scenes

 * Kota is the first Primary Rider since Tsukasa Kadoya who does not make his debut as a cameo appearance in the Summer Movie of his predecessor, instead debuting in the final episodes of that series.
 * It's sort of amusing how Kazuraba has a set of Lockseed Arms associated with the strawberry, with the fruit's name in Japanese being "Ichigo".
 * "Ichigo" can be read as "Number 1" when the "go" kana is given an elongation, the name of the very first Kamen Rider, Takeshi Hongo.
 * Gaim would face off against #1 in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, and also using the Showa Rider Lockseed to assume an Arms based on Rider #1. Thus, Gaim has two Ichigo Arms; "Strawberry Arms" and "#1 Arms". Coincidentally, Gaim also assumes the Strawberry Ichigo Arms during the movie.
 * Splitting the two words "Ichi" and "Go" lead to the numbers "1" and "5", as in 15; Kazuraba is the main Rider of the 15th Kamen Rider Heisei Series since the revival with Kamen Rider Kuuga.
 * Additionally, the Ichigo Lockseed was first seen in episode 1, while Ichigo Arms made its debut in the episode 5.
 * Adding the numbers together also yields its LS number, 06.
 * As the fifteenth leading Heisei Rider, the Heisei era now equals the Showa era in main Riders, as Kamen Rider J is officially considered the 15th Showa-Era Kamen Rider. Thus, Gaim is also the 30th main Rider overall.
 * While Suika Arms resembles a Musha Gundam, it's single red optic is more reminiscent of Zeon mobile suits.
 * In a similar vein, Kachidoki Arms' design resembles a lot like Sengoku Astray Gundam, as they have a similar head and shoulder armor design.
 * Gaim's Sengoku Jidai motif mirrors, the Samurai  who was actually born and raised during the Warring States Period in , Gaim's first Super Hero Time partner.
 * Before him, there was the Shinkengers, who appeared in the World of Shinkenger in a crossover two-episode arc with Kamen Rider Decade, although their motif was just traditional samurai, not a specific part of Japan's history.
 * The Ichigo Arms is similar to that of a ninja, making it the first explicit ninja Rider motif since Kamen Rider ZX.
 * The back of Kota's Team Gaim jacket has a picture which consists of a samurai that resembles Kamen Rider Gaim's Orange Arms.
 * ​His suit design is similar to Kotaro Nogami/Kamen Rider New Den-O.
 * Gaim's transformation, along with the other Riders' transformations is similar to the Kamen Rider Den-O series' Riders in that his basic form is briefly glimpsed before the armor forms.
 * Kota's first transformation occurs without him saying "Henshin" first, similar to Yusuke Godai when he willingly transformed into Kuuga Growing Form for the first time.
 * Kota is the first Neo-Heisei Kamen Rider to reveal his transformation to someone close to him; in this case, his sister.
 * Kota's birthday is revealed to be January 30. Like Kaito, he is 20 years old. With a text message placing the first episode as having taken place on its airdate, October 6th 2013, Kota's birth year would be 1993.
 * Gaim's Jimber Arms serve the same purpose as Kamen Rider Kuuga's Rising Forms and Kamen Rider Wizard's Dragon Styles, as upgrades for the base form. Also, each of the Jimber Arms' abilities and finishers share a visual similarity to a past Rider:
 * Jimber Lemon Arms' Sonic Volley finisher is visually similar to Kamen Rider Blade King Form's Royal Straight Flush and Kamen Rider Decade's Dimension Shoot.
 * The start up of Jimber Lemon Arms' Burai Kick is also similar to Kamen Rider Chalice's Spinning Dance.
 * Jimber Cherry Arms' super speed ability is visually similar to Kamen Rider Faiz Axel Form's Start Up and Kamen Rider Kabuto's Clock Up.
 * Jimber Peach Arms' enhanced hearing ability is visually similar to Kamen Rider Kuuga Pegasus Form.
 * The evolution of Gaim's Super Form (Kachidoki Arms) to Final Form (Kiwami Arms) is similar to Kamen Rider Agito who assumed Burning Form before evolving it into his true Final Form, Shining Form.
 * Gaim's Kachidoki Arms' battle catchphrase "Iza, shutsujin!"  is similar to the battle catchphrase "Iza, mairu!"  from , as both catchprases are references to battlecries used by the ancient Feudal samurai to lead their armies to the battlefield.
