List of Kamen Rider Geats characters

Kamen Rider Geats (仮面ライダーギーツ) is a Japanese tokusatsu series that serves as the 33rd installment in the Kamen Rider franchise and the fourth entry in the Reiwa era.

Ace Ukiyo
Ace Ukiyo (浮世 英寿) is a mysterious man who was born in the year 21 BCE as the son of a previous DGP navigator Mitsume and an unnamed previous "Dezashin" (デザ神), who acquired the ability to reincarnate from his subconscious need to find his mother. After competing in the first DGP and its subsequent tournaments, unaware of his parents' past involvements, he gained additional abilities and earned the title of Dezashin for his undefeated winning streak throughout his succeeding reincarnations across the centuries while attempting to wish for Mitsume's return so he can ask her why she granted him his initial ability. In the present, after losing his pet dog Constantine in a car accident and graduating from high school, Ace becomes a celebrity, referred to as the "Star of the Stars of the Stars" (スター・オブ・ザ・スターズ・オブ・ザ・スターズ), after winning the "Daybreak" DGP and later makes DGP staff members Tsumuri and Girori part of his family after winning the "Encounter" DGP, intending to use the wish he will gain from winning the "Conspiracy" DGP to further infiltrate the organization and uncover the reason behind Mitsume's disappearance. As rules are put in place to limit him, his reincarnations come to light before Ace declares war on the DGP upon discovering what the tournament organizer Suel did to his parents. Ace manages to prevent Suel from erasing the world by fully awakening the power he inherited from his mother, becoming the Creator God (創世の神) and recreating the world based from his memory with everyone aware of the now absent DGP's existence. Ever since acquiring the power of the Boost MarkIII Buckle, Ace prepares his death at the hands of Black Tsumuri, to revive himself as a god per Mitsume's tips, and properly destroys Suel, thereby erasing the DGP and restoring peace properly.

Utilizing the Desire Driver, Ace can transform into the kitsune-themed Kamen Rider Geats. While transformed, he is adorned with the Geats Tail (ギーツテイル) scarf. His primary Form Raise Buckles are Magnum and Boost, which he can use to assume Magnum Form (マグナムフォーム) and Boost Form (ブーストフォーム) respectively. He can also use the Magnum and Boost Buckles at once to assume either Magnum Boost Form (マグナムブーストフォーム) or Boost Magnum Form (ブーストマグナムフォーム). Magnum Form first appears in the film Kamen Rider Revice the Movie: Battle Familia.
 * During the "Conspiracy" DGP, Ace acquires a Fever Slot Buckle, which he can use in conjunction with either the Magnum Buckle to assume Fever Magnum Form (フィーバーマグナムフォーム) or the Boost Buckle to assume Fever Boost Form (フィーバーブーストフォーム). In these forms, his Geats Tail evolves into the Fever Cross Tail (フィーバークロステール).
 * During the "Lamentation" DGP, Ace acquires the Boost MarkII Buckle, which he can use either on its own to assume the evolved Boost Form MarkII (ブーストフォームマークII) or in conjunction with Ziin's Laser Raise Riser to assume the hybrid Laser Boost Form (レーザーブーストフォーム).
 * During the "Longing" DGP, Ace acquires the Boost MarkIII Buckle, which he can use either in its one-piece state to assume the imperfect Boost Form MarkIII (ブーストフォームマークIII) or as the two-piece Boost MarkIX Buckle to transform into his nine-tailed fox-themed ultimate form; Kamen Rider GeatsIX (仮面ライダーギーツIX).

Four Aces
The Four Aces (4人の英寿) refers to the four iterations of Ace Ukiyo in the film, Kamen Rider Geats the Movie: Four Aces and the Black Fox. As a result of Mela's machinations, Ace splits into four versions of himself, each representing one of his four key traits and thus losing the power of creation. Mela absorbs three of the clones to become Kamen Rider XGeats, forcing the remaining clone to fight against the former when his comrades are defeated.

As with the original Ace, his four split clones are also portrayed by Hideyoshi Kan.


 * Ace of Power (力の英寿): The clone who represents Ace's brute strength, his lack of common sense means that he requires the help of others to guide him.
 * Ace of Wisdom (知恵の英寿): The clone who represents Ace's genius intellect, at the cost of having motion sickness and poor physical fitness.
 * Ace of Luck (運の英寿): The clone who represents Ace's amazing luck, able to turn the probability of the situation to his favor.
 * Ace of Heart (心の英寿): The last of the Ace clones who represents his heart, hence bearing the strongest will despite being the weakest. He was left behind when Mela absorbed the rest of the clones to become XGeats. Despite being useless in the field, Ace tries to prevail and his resolve resonates with the rest of the DGP Riders to create the Geats Oneness ID Core, the Oneness Buckle, and the Kamen Rider Geats (Oneness Ver.) Ride Chemy Card. Using these items in conjunction with the Boost MarkIII Buckle, Ace transforms into the rainbow-themed Kamen Rider Geats Oneness (仮面ライダーギーツワンネス), allowing him to compensate for the lack of his power of creation and fight on par with XGeats.

Future Ace
The white-haired version of Ace Ukiyo is his future self from 1,000 years later which appeared in the V-Cinema Kamen Rider Geats: Jyamato Awaking. Unable to prevent God Jyamato's uprising and losing his friends in the process, Ace becomes nihilistic and collaborates with the alternate Niramu to return to the past to prevent God Jyamato's reawakening, fighting against his former friends and present self in the process. However as they were able to avert the crisis on their own, the future Ace became convinced to trust humans once again and returned to his original timeline.

Throughout his time in the tournament, he records himself via video phone to archive his experience in case he loses his memories, with Tsumuri allowing it after Keiwa assures her that they are intended for his eyes only,  After sustaining injuries that cause him to be eliminated during the penultimate round of the tournament, Keiwa temporarily loses his motivation until he becomes forcibly involved in the "Conspiracy" DGP, where Ace helps him regain his memories while Girori provides him with a new Desire Driver from a retiring player.

Later, after Sara's supposed demise, his inner demon is able to possess him. Consumed by his inner demon's possession, Keiwa's granted wish during the second round of the "Creation" DGP goes horribly wrong, such as unknowingly reviving irredeemable criminals who died in previous tournaments with his recently revived family killed by Kamen Rider Tarbon. Until Ace temporarily sacrifice his own freedom to undoes Keiwa's mistaken wish, and had Daichi to make amends to make a serum to revive and free innocent casualties from the previous events, starting from Sara, allowing Keiwa to return to the righteous.

Due to what happened, Neon is protected by foreign bodyguards hired by her abusive mother Irumi. Following her participation in the "Encounter" DGP, Neon returns to being her parents' subservient daughter until Kōsei allows her to compete in subsequent tournaments, during which she learns of her family's connection to the organization and her origins before she is encouraged by her supporter, Kyuun, to overcome her past and move forward to honor Akari's memory.

Ever since, Michinaga became cynical, believing that all Riders are self-serving, and competes in the DGP to fulfill Tōru's desire for a landmark in his hometown along with his own to destroy the Kamen Riders and eventually the DGP itself. After Ace is eliminated during the "Conspiracy" DGP, Michinaga's overconfidence leads to him being fatally wounded during the final round. Following the tournament's conclusion, Michinaga's body ends up in Archimedel's garden, where he is resurrected due to prolonged usage of the Zombie Buckle, and escapes. Despite being brought back to the Jyamato garden by Niramu and Samasu to be killed, Beroba intervenes and convinces Michinaga to fight for the Jyamato to achieve his wish. He eventually wins the JGP, becomes the "Jyamashin" (ジャマ神), and sets out to fulfill his wish as well as destroy the DGP. But his wish to destroy solely other Kamen Riders made him weak against non-Kamen Rider combatants like the Jyamato, which remained in effect after Ace restored Michinaga's humanity in the aftermath of Desire Royale finale. Although he regain partial of its power to kill Beroba in the near end of the "Creation" DGP. Ultimately, Michinaga begins to discard his ego and atone to his past deeds, when Daichi infected Keiwa's sister, Sara, with a Stage 2 parasite Jyamato and tricks the former into seemingly murdering her by mistake that leads to Keiwa's downfall, much to his horror. With the DGP erased at cost of losing the memory of Ace's existence, Michinaga finally moves on from Tōru's passing.

Nonetheless, she gradually opens up to Ace and the other DGP Kamen Riders before manifesting abilities similar to the Creation Goddess's. But her awakened ability makes her a new target of the DGP members who are loyal to Suel, who wants her to be their replacement Creation Goddess, until Ace absorbs it from her while temporarily costing his own freedom. Alongside Kyuun and Ziin, Tsumuri is spared from being erased by Ace when he erased the DGP from existence.

Tsumuri is portrayed by Kokoro Aoshima (青島 心).

DGP
The Desire Grand Prix (デザイアグランプリ) is a cult-like totalitarian organization which governs the future, where Earth was ruined and abandoned and the entire human race exists as data beings, that hosts a survival reality show of the same name that can be viewed across time and space. Originally, the competitors only fought for fame and glory with no casualties, their only prize being a gold coin and recognition as the strongest warriors of their time. This changed when the organization decided to increase the stakes by recruiting players to become Kamen Riders and defeat the mysterious "Jyamato" in a series of tournaments in exchange for granting the winner's wish. Once a chosen participant joins, they are bound by the game's rules, such as protecting civilians from Jyamato, and are forced to keep playing until they are either killed, removed from reality, disqualified, or find a replacement and returned to their regular lives with no memory of the DGP nor motivation towards fulfilling their wish.

During the "Divergence" DGP, new rules are instated in response to Ace's winning streak and Girori's misconduct, including allowing viewers to vote for the winner of each round and the players having to determine and eliminate the player designated as the "Dezastar" (デザスター), who has been given secret orders from the DGP staff before they reach the final round and automatically win the season. However, Beroba's faction and the Jyamato steal the Game Master's Vision Driver and replace the DGP with a full-scale invasion-themed survival series called the Jyamato Grand Prix (ジャマトグランプリ). Suel eventually changes the game's format into a second season of the Desire Royale where the winner gets to decide the fate of the DGP and the world with the additional rule that those who get eliminated are forever banned from becoming Kamen Riders. However, it turns out to be part of the Grand End (グランドエンド), an emergency initiative that the entire management will return to their original world and leaving those behind their memories wiped out.

With Suel's death, Ace erases the DGP from existence and undoes their damage, with Ziin, Kyuun, and Tsumuri being spared, and Girori voluntarily letting himself be erased along with the staff who are loyal to Suel. To dedicate Ace's sacrifice, the DGP is reformed under Ziin's new direction.

Each participant carries a Desire Driver (デザイアドライバー) belt, which can combine with a personalized ID Core (IDコア) disc to transform them into a base Entry Form (エントリーフォーム) Kamen Rider, and a Spider Phone (スパイダーフォン), which can switch between Phone Mode (フォンモード) and Spider Mode (スパイダーモード). The Riders can also equip their Desire Driver with one to two Raise Buckles; which they can earn from Mission Boxes (ミッションボックス) by defeating Jyamato, completing Secret Missions (シークレットミッション), or getting help from their Supporters (サポーター), fans from the future; to gain additional armor with multiple configurations, with rare Jyamato offering stronger Raise Buckles.

The Supporters utilize Raise Riser Cards (レイズライザーカード) in conjunction with the Laser Raise Riser (レーザーレイズライザー) raygun to transform into a customized Kamen Rider form that embodies the user's desires. A Supporter with the DGP's premium membership can use a dark copy of their Raise Riser Card called a Black Raise Riser Card (ブラックレイズライザーカード) to transform into a Jyamato-esque Premium (プレミアム) warrior form.

High-ranking DGP staff members utilize the Providence Card (プロビデンスカード) in conjunction with the Laser Raise Riser's successor, the Vision Driver (ヴィジョンドライバー) belt, to transform into an eyeball-themed Kamen Rider, which grants them access to the Creation Goddess (創世の女神) and approve the winner's wish. The Game Master (ゲームマスター) possesses one to manage the DGP's system while Niramu possesses the second.

Like the participants of DGP, members of the DGP guard also utilize the Desire Drivers to transform into Guard Riders (警備隊ライダー), with a task to preserve the tournament's rules from being violated.

Girori
Girori (ギロリ) is the salon concierge of the DGP who is later revealed to be the organization's masked Game Master. Realizing that Ace is using his winning streak to the infiltrate the DGP, despite managing to conceal his true position when Ace used his wish from winning the "Encounter" DGP to make the man his father, Girori decides to have him eliminated in the next tournament with Win's help. When Ace outwits Win, Girori decides to break the rules and abuse his position to intervene personally by becoming Kamen Rider Glare during the "Conspiracy" DGP's penultimate round and force an unwilling Win to eliminate Ace. Upon learning Ace planned ahead and had himself reinstated with full knowledge of Girori's identity, the latter abuses his position to arrange for Keiwa and Neon to kill Ace for him, but they expose him during a broadcast, leading to Niramu firing Girori. Upon his return in finale of DGP, Girori ultimately learns the truth about the dark side of the organization and joins Ace's side. Once Suel is killed, Girori voluntarily lets himself be erased alongside other DGP staffs who are loyal to Suel.

Utilizing the Vision Driver, Girori can transform into the black-colored Kamen Rider Glare (仮面ライダーグレア). While transformed, he gains the use of five Hypnoray (ヒュプノレイ) drones, which can attach onto other Riders to force them into serving as his GM Rider (GMライダー) puppets and become living bombs, for combat assistance.

Girori is portrayed by Shugo Oshinari (忍成 修吾).

Win Hareruya
Win Hareruya (晴家 ウィン) is an energetic former punk rock guitarist of Weather Hearts (ウェザーハーツ) who tried to become a famous musician. Unfortunately, following his band's unexpected disbandment, Win almost suffered a midlife crisis, until he took a part-time job as a DGP staff member instead with help from his grandfather, whose company sponsors the organization. He initially appears in the "Encounter" DGP as a mysterious guest Rider for the teamwork round following Kanato Sumida's elimination, during which he is instructed to conceal his identity from the other participants. Following this tournament's end, Win resolves to become more than a silent non-player Rider in the "Conspiracy" DGP while Girori tasks him with sabotaging Ace. However, the other Kamen Riders learn of Win's motives when Michinaga catches him in the act of sabotaging Ace, resulting in Win eventually losing his DGP privileges for leaking vital information on the organization to Ace and being turned into a GM Rider by Girori, who he thought to have killed him in an attempt to destroy Ace. However, Win survived Girori's attempt but suffers heavy injuries, until Suel recovers him during the second Desire Royale tournament. Nevertheless, Win remains to aid Ace behind the scenes. With the DGP erased at cost of losing the memory of Ace's existence, Win got his old rock band back together and becomes famous without any compromises.

Utilizing the Desire Driver, Win can transform into the grizzly bear/jack-o'-lantern-themed Kamen Rider PunkJack (仮面ライダーパンクジャック). While transformed, he is adorned with the PunkJack Cloak (パンクジャックマント), which grants increased jumping capabilities. His primary Form Raise Buckle is Monster, which he can use to assume Monster Form (モンスターフォーム).
 * During the "Conspiracy" DGP, Win acquires a Fever Slot Buckle, which he can use in conjunction with the Monster Buckle to assume Fever Monster Form (フィーバーモンスターフォーム). In this form, his PunkJack Cloak evolves into the Fever Cross Cloak (フィーバークロスマント).
 * During the events of the web-exclusive special, Geats Extra: Kamen Rider PunkJack, Win's past reveals that he initially started out working for the DGP as a Guard Rider before receiving his own ID Core to become Kamen Rider PunkJack. Like Na-Go, his original primary Form Raise Buckle was Beat, which he could use to assume Beat Form.

Win Hareruya is portrayed by Tsubasa Sakiyama (崎山 つばさ).

Niramu
Niramu (ニラム) is the producer of the DGP who believes in fair play, responding to Girori's conduct by first providing Ace with the Command Twin Buckle at Ziin's behest and then personally firing Girori. During the second Desire Royale, Niramu plans to quickly regain control of the DGP and move it to a different era of Earth's history before a winner is selected. However, when he begins to oppose Suel's machinations for what he did to Mitsume while trying to protect Tsumuri from becoming the Creation Goddess, Niramu is shot by Samasu from behind and ultimately entrusts Ace to undo the DGP's mistakes before dying.

Utilizing the Vision Driver, Niramu can transform into the white-colored Kamen Rider Gazer (仮面ライダーゲイザー). While transformed, he gains the use of five Dominion Ray (ドミニオンレイ) drones, which can create energy shields, for combat assistance.

Niramu is portrayed by Ryo Kitamura (北村 諒).

Samasu
Samasu (サマス) is an assistant producer of the DGP. She later succeeds Niramu as the new producer by killing him and taking his Vision Driver. Due to being loyal to Suel, whom Ace properly killed, Samasu is erased from existence by the latter.

Samasu is portrayed by Seia Yasuda (安田 聖愛).

Chirami
Chirami (チラミ) is Girori's replacement as the Game Master, taking over during the "Divergence" DGP until Beroba steals his Vision Driver. Though he eventually reclaims it, Chirami is killed by Michinaga during the Desire Royale.

Utilizing the Vision Driver, Chirami can transform into a red eye-themed version of Glare known as Kamen Rider Glare2 (仮面ライダーグレア2).

Chirami is portrayed by Shigenori Yamazaki (山崎 樹範).

Mitsume
Mitsume (ミツメ) is Ace's missing mother and a former DGP navigator from a distant future. When Suel rebranded the DGP, Mitsume disagreed and attempted to resign while also secretly having a forbidden relationship with Ace's unnamed father, the previous Dezashin from a distant past before the Common Era Mitsume gained the ability to alter reality, which also granted Ace a reincarnation ability after his first incarnation's birth. However, when DGP found about this retaliation and caught Ace's father, Mitsume was able to hide her son's existence from them, before being caught and forcibly turned into the Creation Goddess to power the organization's wish-granting system, at the cost of the desires of eliminated DGP players through abusing her ability. Although she can temporarily regain her free will to help her son, such as granting the means to create the Boost MarkII Buckle along with reversing Suel's attempt to simply wish Ace out of existence. Ultimately, Mitsume sacrifices her life force to unlock her son's full potential of his birth power.

Mitsume is portrayed by Nana Isaki (井咲 奈々) and voiced by Yuka Terasaki (寺崎 裕香).

Suel
Suel (スエル) is the DGP's executive producer who rebranded the DGP into a reality show following the first tournament, and forcibly turned Mitsume into the Creation Goddess as well as banished her lover, Ace's father. Suel mostly observed the DGP games from the shadows until Michinaga won the JGP and a revived Ace formally declared war on the DGP. This convinces Suel to host a second Desire Royale to give the two men and the other Kamen Riders a chance to decide the fate of the DGP. But the tournament is revealed to be a distraction Suel devised to get the Kamen Riders to destroy each other while he arranges for the DGP to transfer to another period, intending to erase the world. But he is defeated by GeatsIX, deciding to see the world Ace intends to create while biding his time. He would later return after the defeat of his lackey Zitt to declare a final DGP. However, he cannot depower nor erase Ace from existence, and is properly killed by him.

Although a fellow user of the Vision Driver, Suel assumes the Kamen Rider forms of his deceased DGP staff, with his forms being variants from their previous users:
 * Kamen Rider Gazer: A pink eye-themed version of Gazer, which Suel accesses by utilizing Niramu's Vision Driver. Due to Suel's high authority, Gazer can access its full power through the removal of limiters imposed by the Vision Driver. After being defeated by GeatsIX, Suel abandons this form and returns the Vision Driver to Samasu.
 * Kamen Rider Regad Omega (仮面ライダーリガドΩ): A Cyclops-themed version of Regad, which Suel accesses by utilizing the Zillion Driver and fusing himself with the cameras linked to the audience from the future who share Zitt's sense of sadism. While transformed, the cameras are fused into his armor and function as additional eyes.

Suel is portrayed by Masashi Takada (高田 将司) and voiced by Yoshitsugu Matsuoka (松岡 禎丞), who also voices the Laser Raise Riser and the Vision and Zillion Driver systems.

Zitt
Zitt (ジット) is a Game Master who supervises the bad endings to ensure all participants always lose the contest as Suel's right-hand man. He is tasked to retrieve Tsumuri for the DGP while eliminating Ace and his allies as Chirami's replacement, and attempt to deceive Keiwa into DGP's thrall. He also provided Beroba and Kekera with Black Raise Riser Cards to assume stronger, Jyamato-like forms that are not designated as Kamen Riders, giving them an edge against Michinaga by bypassing the boon from his wish while also able to overpower Riders with regular forms. While Tsumuri is in the Creation Goddess state before her escape and reverts to normal, Zitt takes a sample from her tears to create the power of a Destruction Goddess. Despite being defeated by Geats, he let himself be absorbed by Suel.

Utilizing the Sirius Card (シリウスカード) in conjunction with the Vision Driver's successor, the Zillion Driver (ジリオンドライバー) belt, Zitt can transform into a crimson-colored evolution of Glare/Gazer known as Kamen Rider Regad (仮面ライダーリガド). While transformed, he gains the use of two Sovereign Ray (ソブリンレイ) drones for combat assistance.

Zitt is portrayed by Ryuji Sato (佐藤 流司).

Black Tsumuri
Black Tsumuri (黒いツムリ) is a clone of Tsumuri that Zitt creates to make a new Destruction Goddess (破壊の女神). Being created to be loyal to Suel, the Black Tsumuri is erased by Ace, after he killed Suel properly.

Black Tsumuri is portrayed by Kokoro Aoshima, who also portrays Tsumuri.

Raise Buckles
The Raise Buckles (レイズバックル) are a series of belt buckle-like items used by the Riders in the DGP to access new powers and abilities. Using a Raise Buckle on the Desire Driver's right-hand side affects the Rider's upper body while using one on the left-hand side affects their lower body. If two Raise Buckles are used at once for the Dual On (ヅアルオン) combining function, a Rider can switch both sides of the Desire Driver to the opposite side via the Revolve On (リヴォルヴオン) rotating function.

The two primary types of Raise Buckles are the plentiful small-sized Armed (アームド) Raise Buckles, which grant the players a corresponding Armed Weapon (アームドウエポン), and the rare large-sized Form (フォーム) Raise Buckles, which allow the players to assume armor-based forms. Unlike the Armed Raise Buckles, the Form Raise Buckles' designs have a matching center design denoting their primary halves. As these Raise Buckles are difficult to find normally, most of them can be found quickly through either Secret Missions or emergency situations. Additionally, there are the special-exclusive Legend Rider (レゲンドライダー) Raise Buckles, which allow the players to assume armor forms that grant weaponry and powers based on past Kamen Riders:
 * Magnum (マグナム): Equips the user with the twin arm/leg-mounted Armored Guns (アーマードガン) and grants the use of the Magnum Shooter 40X (マグナムシューター) firearm, which can switch between Handgun Mode (ハンドガンモード) and Rifle Mode (ライフルモード); the latter of which has an alternate Machine Gun Mode (マシンガンモード) that can be accessed by combining with the Magnum Buckle. Its primary half is the Boost Buckle. The Magnum Shooter 40X can also be used in Powered Builder Form by combining the Powered Builder Buckle and a small-sized Weapon (ウエポン) Raise Buckle based on the aforementioned firearm.
 * Boost (ブースト): Grants increased mobility and the use of the Boostriker (ブーストライカー) motorcycle, which can change from Bike Mode (バイクモード) to an Animal Mode (アニマルモード) based on the user's motif when they perform a Boost Time (ブーストタイム) finisher. Unlike other Form Raise Buckles, the Boost Buckle will eject from the user's Desire Driver and fly away after a Boost Time finisher is performed, and is the most difficult to find. Its primary half is the Magnum Buckle.
 * Boost MarkII (ブーストマークII): An upgraded version created by Mitsume from five copies of the Boost Buckle that grants superhuman speed, pyrokinesis, and the use of the Beast Mode (ビーストモード) ability to transform the user into an evolved form of the Boostriker's corresponding Animal Mode via the Revolve On function. However, using it drains the user's stamina, causing them to faint after canceling their transformation. By setting a Laser Raise Riser into the Desire Driver alongside the Boost MarkII Buckle, the user stabilizes their stamina and gains gyrokinesis.
 * Boost MarkIII (ブーストマークIII): A two-in-one upgraded version of the Boost MarkII Buckle created by Ace from his rage that grants the use of the Geats Buster QB9 (ギーツバスター), which can switch between Railgun Mode (レールガンモード) and Blade Mode (ブレードモード).
