Kamen Rider Gaim

Main characters

Kota Kazuraba

Kota Kazuraba (葛葉 紘汰, Kazuraba Kōta) is an earnest and cheerful yet naïve and short-sighted young adult who wants to help others, but sometimes ends up causing more trouble than good. He was originally the second-in-command of Team Gaim before quitting the team to pursue odd jobs and help his older sister, Akira, after their parents died, before eventually getting a job at Drupers. However, his life is changed after Team Gaim's leader Yuya Sumii arranges a meeting with Kota to show him something that could help their team. This leads Kota to search for Sumii in what he later learns is the Helheim Forest, finding a Sengoku Driver (戦極(センゴク)ドライバー, Sengoku Doraibā; Warring Driver) belt that his friend bought from the mysterious Lockseed Dealer Sid, and an Inves that Kota manages to destroy via the Sengoku Driver and a padlock-like Lockseed (ロックシード, Rokkushīdo) device. While figuring out how best to use his newly acquired powers, Kota witnesses his rival, Kaito Kumon's, summoned Inves go on a rampage and becomes determined to protect people as the samurai-themed Kamen Rider Gaim. After he rejoins Team Gaim in the apparently missing Sumii's stead, Kota inspires others to become Armored Riders themselves.

In the middle of the series, Kota continues his fight towards the corrupt Yggdrasil Corporation after discovering the company's shady attempts at covering up the Inves attacks with the Beat Riders being scapegoated as a result. Kota then obtains Kiwami Arms to oppose the Overlord Inves' invasion on Earth and eventually duels against Kaito in the final battle to obtain the Forbidden Fruit. With Kota emerges as the victor, he ascends to the title of Man of the Beginning, removing Helheim's influence on Earth to another planet as their new ruler alongside Mai.

Utilizing one of several Lockseeds in conjunction with the Sengoku Driver, Kota can transform into Kamen Rider Gaim. While transformed, he wields the Musou Saber (無双セイバー, Musō Seibā; Unrivaled Saber) pistol sword, which can combine with certain Arms Weapons (アームズウェポン, Āmuzu Wepon) to access alternate modes. His personal Lock Vehicle (ロックビークル, Rokku Bīkuru) is the Sakura Hurricane (サクラハリケーン, Sakura Harikēn) motorcycle, which is summoned from the eponymous Lockseed. Additionally, he can use other Lockseeds to assume varying Arms (アームズ, Āmuzu) forms that each possess a unique Arms Weapon, which are as follows:

Orange Arms (オレンジアームズ, Orenji Āmuzu): Kota's default form accessed from the Orange (オレンジ, Orenji) Lockseed that grants the use of the Daidaimaru (大橙丸; Great Orange Circle) sword, which can combine with the Musou Saber to access the former's double-bladed Naginata Mode (ナギナタモード, Naginata Mōdo).

Kaito Kumon

Kaito Kumon (駆紋 戒斗, Kumon Kaito) is the brooding leader of Team Baron who bears a strong hatred towards the Yggdrasil Corporation, who bought out his father's construction company as part of their redevelopment plans for Zawame. As a result, Kaito grew up in a poor household, his father became abusive towards him and his mother, and both of his parents eventually committed suicide, leading to Kaito being placed into an orphanage at a young age. This childhood cemented a survival of the fittest-like mentality in his later years and fostered a personal desire to acquire power for himself as he believes he cannot trust anyone else.

In the present day, Kaito ascends to the leadership of Team Baron and obtains the means to become the knight-themed Kamen Rider Baron (仮面ライダーバロン, Kamen Raidā Baron) as part of the Inves Games. When Yggdrasil made their move to turn the Beat Riders as scapegoats, Kaito retires from Team Baron and put Zack as his replacement leader while he launches his fight against the company as an independent Armored Rider. During the Helheim's invasion on Earth, Kaito joins forces with the rest of the Armored Riders against the invaders, but his infection and determination to reverse the status quo of the weak twisted his mind to mutate into the Overlord Inves form; Lord Baron (ロード・バロン, Rōdo Baron).

Despite going to an elite school, Mitsuzane wishes to follow his own path rather than follow in his brother's. After his friend Kota Kazuraba is nearly killed by Kamen Rider Zangetsu, Mitsuzane convinces Sid to give him a Sengoku Driver so he can become Team Gaim's second Armored Rider, the Chinese soldier/dragon-themed Kamen Rider Ryugen (仮面ライダー龍玄, Kamen Raidā Ryūgen).

Upon discovering Takatora is Zangetsu, Mitsuzane initially resolves to uncover the truth behind the Yggdrasil Corporation's ties to the Helheim Forest. However, his desire to protect Kota and their mutual friend Mai Takatsukasa from the truth and discovery of what happened to Team Gaim member Yuya Sumii leads Mitsuzane to help Takatora conceal information on the Helheim Forest instead. Eventually in the middle of the series, Mitsuzane went insane from the influences of both the Yggdrasil workers and the Overlords, secretly opposing Kota and the Armored Riders from the shadows before his treachery is made public. He eventually falls into despair once Ryoma's manipulations caused him to seemingly kill both Kota and Mai at the same time, eventually distancing himself from his former friends out of guilt. Only through the arrival of Kogane, Mitsuzane is able to obtain his closure after meeting Kota again, the two finally burying the hatchet before he joins his brother in hunting the Yggdrasil remnants.

Utilizing the Budou (ブドウ, Budō; Grape) Lockseed in conjunction with the Sengoku Driver, Mitsuzane can transform into Kamen Rider Ryugen Budou Arms (ブドウアームズ, Budou Āmuzu).

Having learned to dance in her youth, she believes her transition into a Beat Rider does not affect her ideals as she tries to teach the others how to dance better, becoming an older sister figure to them. During the Helheim invasion on Earth, Mai is entrusted with the Forbidden Fruit by Rosyuo to safeguard it from Redyue's machinations and ascends to the role of the Woman of the Beginning. However, her attempt at trying to alter the past gets her trapped in an alternate timeline, necessitating for Kota to win the fight against Kaito to bring her back and earning the Forbidden Fruit to himself.

After detecting a high frequency of Crack portals in Zawame City, the company established the Yggdrasil Tower around the city's "sacred tree" for research purposes, disguising their true agenda by using their expertise in several fields and socioeconomic aspects of city-dwelling to redevelop Zawame to prevent widespread panic amongst the populace. Due to their omnipresence however, many of Zawame's citizens feel as if they are living in a "jōkamachi (城下町, castle town)" rather than a bustling city.

He was originally an orphan until he was taken in by Yggdrasil's owner, Amagi Kureshima, who recognized the boy's talents and potential for furthering Yggdrasil's goals. Over the years, Ryoma would go on to become Amagi's right hand, develop Lockseeds, and become acquainted with Amagi's eldest son, Takatora Kureshima. Despite this, Ryoma grew to see the latter as a fool for trying to save humanity first and lacking his father's ambition, leading to Ryoma secretly acting on his own agenda by obtaining the Forbidden Fruit and acquiring its power rather than save the world from the Inves.

Following an encounter with Mitsuzane Kureshima and Sid, Redyue feigns defeat before leading them to the Forbidden Fruit and manipulating the latter into attacking Roshuo. She later reveals to Mitsuzane her desire to claim the Forbidden Fruit's power for herself. To achieve this, she convinces Roshuo to give her the fruit in exchange for using Earth's technology to revive his queen, with the intention of betraying him later on.

Kogane (コウガネ, Kōgane) is a manifestation of the Forbidden Fruit created by the previous Overlords in the past. When one of Ryoma Sengoku's experiments goes awry, Kogane awakens and kills him before taking on the form of a middle-aged man and creating a Locust Monster to either possess a human host to revive themself or infect humans and turn them into mindless monsters. Because of their existence on Earth, Kogane causes most of the Armored Riders to turn against each other in their search for the Golden Fruit. All the while, they masquerade as Yuya Sumii to get close to and manipulate Kota Kazuraba. They later defeat and brainwash him into becoming its vassal, Kamen Rider Gaim Yami, to hunt down Lapis.

Coming across Kota Kazuraba and Mai Takatsukasa's planet, Megahex accessed the former's mind and learned of Earth's existence before seemingly destroying him and capturing Takatsukasa. Upon reaching Earth, Megahex creates facsimiles of Ryoma Sengoku and Kaito Kumon to serve him and assimilates the Cyberoid ZZZ android to become ZZZ Megahex (ZZZメガヘクス, Surī Zetto Megahekusu). However, the Kaito facsimile betrays him before ZZZ Megahex is weakened by Kota, the Armored Riders, Kamen Rider Drive, Mashin Chaser, Heart, and Brain before Kamen Riders Gaim and Drive travel to Planet Megahex and destroy the alien.
