Ace Ukiyo (浮世 英寿, Ukiyo Ēsu) is a mysterious man who was born before 1 A.D. who acquired the ability to reincarnate from his mother Mitsume after she disappeared. After competing in the first DGP and its subsequent tournaments, unaware of Mitsume's work with them, he gained additional abilities and earned the title of "Desashin" (デザ神, Dezashin, Desire Deity) 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, Ace becomes a famous celebrity 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.[1][2][3][4][5] As rules are put in place to limit him, his reincarnations come to light before Ace declares war on the DPG upon discovering what the tournament organizers did to his mother.[6][7][8][9][10]

Following this, Keiwa competes to fulfill his new wish of reviving dead DGP players and gains a job at his favorite soba restaurant.[12][17][5][18][19]

Michinaga Azuma (吾妻 道長, Azuma Michinaga) is a construction worker, former high school delinquent, and the runner-up of the "Daybreak" DGP with an ambitious desire to surpass Ace Ukiyo, whom he considers a rival and blames for the death of his best friend and fellow former delinquent, Tōru Imai, who Ace failed to save from traitorous Kamen Riders during a previous DGP. 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.[1][2][16][24][25][22] After Ace is eliminated during the "Conspiracy" tournament, Michinaga's overconfidence leads to him being fatally wounded during the final round.[26] 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.[27][6][28] Despite being brought back to the Jyamato garden by Niram and Samas to be killed, Beroba intervenes and convinces Michinaga to fight for the Jyamato to achieve his wish.[29] He eventually wins the JGP, becomes the "Jyamashin" (ジャマ神, Jamashin, Jyamato Deity), and sets out to fulfill his wish as well as destroy the DGP.[9][30]

During the events of the film Kamen Rider Geats × Revice: Movie Battle Royale, which is set between his death and waking up in Archimedel's garden, Michinaga is temporarily revived for the Desire Royale.

The Desire Grand Prix (デザイアグランプリ, Dezaia Guran Puri, DGP) is a cult-like organization that hosts a virtual reality-based survival reality show of the same name that can be viewed across time and space.[31] 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.[2][14][24][3]

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 "Desastar" (デザスター, Dezasutā), who has been given secret orders from the DGP staff, before they reach the final round and automatically win the season.[6][29] 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, Jamato Guran Puri, JGP),[6][32][31][33]. Sueru 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.[10]

Each participant carries a Desire Driver (デザイアドライバー, Dezaia Doraibā) belt, which can combine with a personalized ID Core (IDコア, Ai Dī Koa)[lower-alpha 1] disc to transform them into a base Entry Form (エントリーフォーム, Entorī Fōmu)[lower-alpha 2] Kamen Rider, and a Spider Phone (スパイダーフォン, Supaidā Fon), which can switch between Phone Mode (フォンモード, Fon Mōdo) and Spider Mode (スパイダーモード, Supaidā Mōdo). 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, Misshon Bokkusu) by defeating Jyamato, completing Secret Missions (シークレットミッション, Shīkuretto Misshon), or getting help from their Supporters (サポーター, Sapōtā), fans from the future; to gain additional armor with multiple configurations,[2] with rare Jyamato offering stronger Raise Buckles.[13]

The Supporters utilize Laser Raise Riser (レーザーレイズライザー, Rēzā Reizu Raizā) rayguns in conjunction with a Raise Riser Card (レイズライザーカード, Reizu Raizā Kādo) to transform into a customized Kamen Rider form that embodies the user's personal desires.[6][32][31][33]

High-ranking DGP staff members utilize the Laser Raise Riser's successor, the Vision Driver (ヴィジョンドライバー, Vijon Doraibā) belts, in conjunction with a Providence Card (プロビデンスカード, Purobidensu Kādo) to transform into an Eye of Providence-themed Kamen Rider,[8] which grants them access to the Goddess of Creation (創世の女神, Sōsei no Megami) and approve the winner's wish. The Game Master (ゲームマスター, Gēmu Masutā) possesses one to manage the DGP's system while Niram possesses the second.[32][31]

Tsumuri (ツムリ) is a mysterious navigator for the DGP who provides the players with equipment and information[1][2] while reporting to her masked superior, later revealed to be Girori.[24] After Ace wins the "Encounter" tournament, he uses his wish to make Tsumuri his older sister, much to her dismay despite being disgusted by her co-workers attempting to sabotage Ace.[4] Nonetheless, she gradually opens up to Ace and the other DGP Kamen Riders before manifesting abilities similar to the Goddess of Creation's.[30]

Girori (ギロリ) is the salon concierge of the DGP who is later revealed to be the organization's masked Game Master.[1][2] 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.[4] 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.[23] 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 Niram firing Girori.[26][27]

Utilizing the Vision Driver, Girori can transform into the black-colored Kamen Rider Glare (仮面ライダーグレア, Kamen Raidā Gurea). While transformed, he possesses the ability to attach Hypnoray (ヒュプノレイ, Hyupunorei) drones from his armor onto other Riders, forcing them to serve as his GM Rider (GMライダー, Jī Emu Raidā) puppets and use them as living bombs.[23]

Win Hareruya (晴家 ウィン, Hareruya Win) is an energetic punk rock guitarist who tried to become a famous musician, but was forced to take a part-time job as a DGP staff member instead with help from his grandfather, whose company sponsors the organization.[23] He initially appears in the "Encounter" tournament 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" tournament while Girori tasks him with sabotaging Ace.[4][17] 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,[18][23] who eventually kills him in an attempt to destroy Ace.[27] Win is later resurrected by Sueru during the second Desire Royale tournament.[34]

Utilizing the Desire Driver, Win can transform into the grizzly bear/pumpkin/jack-o'-lantern-themed Kamen Rider Punk Jack (仮面ライダーパンクジャック, Kamen Raidā Panku Jakku). While transformed, he is adorned with the Punk Jack Cloak (パンクジャックマント, Panku Jakku Manto), which grants increased jumping capabilities.

When Sueru rebranded the DGP, Mitsume disagreed and attempted to resign. However, she was forcibly turned into the Goddess of Creation to power their wish granting system due to her potential for granting impossible wishes, though she is able to temporarily regain her free will to help her son, such as granting him his ability to reincarnate and the means to create the Boost Mark II Buckle.[3][23][8][22][9]

The Raise Buckles (レイズバックル, Reizu Bakkuru) are a series of belt buckle-like items used by the Riders in the DGP to access new powers and abilities. Utilizing a Raise Buckle on the right-hand side of the Desire Driver affects the Rider's upper body while utilizing 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, Duaru On) 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, Rivorufu On) rotating function.

The two primary types of Raise Buckles are the plentiful small-sized Armed (アームド, Āmudo) Raise Buckles, which grant the players a corresponding Armed Weapon (アームドウエポン, Āmudo Uepon), and the rare large-sized Form (フォーム, Fōmu) Raise Buckles, which allow the players to assume armor-based forms and augment Armed Weapons. 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 also special small-sized Legend Rider (レゲンドライダー, Rejendo Raidā) Raise Buckles, which allow the players to assume armor forms that grant weaponry and powers based on past Kamen Riders and are exclusive to special events:[36]

• Magnum (マグナム, Magunamu): Equips the user with the twin arm/leg-mounted Armored Guns (アーマードガン, Āmādo Gan) and grants the use of the Magnum Shooter 40X (マグナムシューター40X, Magunamu Shūtā Fō Zero Ekkusu) firearm, which can switch between Handgun Mode (ハンドガンモード, Handogan Mōdo) and Rifle Mode (ライフルモード, Raifuru Mōdo) as well as combine with the Magnum Buckle to access its Machine Gun Mode (マシンガンモード, Mashin Gan Mōdo). Its primary half is the Boost Buckle.
• Boost (ブースト, Būsuto): Grants increased offensive capabilities and the use of the BooStriker (ブーストライカー, Būsutoraikā) motorcycle, which can change from Bike Mode (バイクモード, Baiku Mōdo) to an Animal Mode (アニマルモード, Animaru Mōdo) based on the user's motif when they execute a Boost Time (ブーストタイム, Būsuto Taimu) 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 executed, and is the most difficult to find.[2] Its primary half is the Magnum Buckle.
  • Boost Mark II (ブーストマークII, Būsuto Māku Tsū): An upgraded version created 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, Bīsuto Mōdo) ability, allowing the user to transform into an evolved version of the BooStriker's corresponding Animal Mode via the Revolve On function. However, it consumes the user's stamina, which causes them to faint after cancelling the transformation.[7] By utilizing the Boost Mark II Buckle in conjunction with a Laser Raise Riser, the user can stabilize their stamina and gain gyrokinesis.[8]
• Zombie (ゾンビ, Zonbi): Equips the user with the poisonous BerserClaw (バーサークロー, Bāsākurō) gauntlet/sabaton and grants the use of the chainsaw-like Zombie Breaker (ゾンビブレイカー, Zonbi Bureikā) sword. While transforming, the Zombie Buckle produces poisonous liquid capable of dissolving the user's enemies into nothingness.[2]
• Ninja (ニンジャ): Grants ninjutsu and the use of the double-bladed Ninja Dueler (ニンジャデュアラー, Ninja Duarā) sword, which can separate in half to form a pair of daggers.[3]
• Monster (モンスター, Monsutā): Equips the user with either the Monster Glove (モンスターグローブ, Monsutā Gurōbu) gauntlets or the Big Boot (ビッグブーツ, Biggu Būtsu) sabatons.[4] During the events of the film Kamen Rider Geats × Revice: Movie Battle Royale, the Monster Buckle is temporarily used by Kamen Rider Vice for the Desire Royale.
• Beat (ビート, Bīto): Grants symphokinesis and the use of the Beat Axe (ビートアックス, Bīto Akkusu) electric guitar, which can switch between Guitar Mode (ギターモード, Gitā Mōdo) and Axe Mode (アックスモード, Akkusu Mōdo) as well as grant the additional use of cryo-, electro-, and pyrokinesis.[17] During the events of the film Kamen Rider Geats × Revice: Movie Battle Royale, the Beat Buckle is temporarily used by Kamen Rider Revi for the Desire Royale.
• Fever Slot (フィーバースロット, Fībā Surotto): A right-hand side exclusive Raise Buckle that allows the user to randomly summon either the armor of an existing Form Raise Buckle or the Armed Weapon of an Armed Raise Buckle. If the summoned Form Raise Buckle matches the one on the Desire Driver's left-hand side, the user assumes a Fever Form (フィーバーフォーム, Fībā Fōmu), whose power level is increased two-fold without using the Revolve On function. To signify the difference between regular Form Raise Buckle armors, Fever Forms replace the user's personal accessory with a gold-colored Fever Cross (フィーバークロス, Fībā Kurosu) variant. Five copies of the Fever Slot Buckle were created by Girori to counter the Jyamato's increasing power.[5]
• Command Twin (コマンドツイン, Komando Tsuin): A two-in-one Raise Buckle consisting of the orange-colored Command Jet (コマンドジェット, Komando Jetto) Buckle and the blue-colored Command Cannon (コマンドキャノン, Komando Kyanon) Buckle that grants the use of the Raising Sword (レイジングソード, Reijingu Sōdo). Utilizing the Command Jet Buckle on its own allows the user to assume a base Raising Form (レイジングフォーム, Reijingu Fōmu) while utilizing both Command Twin Buckles at once after charging the Command Cannon Buckle in the Raising Sword allows them to assume an armored Command Form (コマンドフォーム, Komando Fōmu), the latter of which can switch between Jet Mode (ジェットモード, Jetto Mōdo) and Cannon Mode (キャノンモード, Kyanon Mōdo) via the Revolve On function.[19][26]
• Powered Builder (パワードビルダー, Pawādo Birudā): A right-hand side exclusive Raise Buckle that equips the user with a pair of manipulators on the front and back of the armor's body as well as combine with one of three Gigant Buckles (ギガントバックル, Giganto Bakkuru), which are stored in the left-hand side exclusive Gigant Container (ギガントコンテナ, Giganto Kontena) Buckle, to grant them a corresponding Gigant Weapon (ギガントウエポン, Giganto Uepon). This set of Raise Buckles first appears in the film Kamen Rider Geats × Revice: Movie Battle Royale.[20] The Powered Builder Buckle can also combine with one of four Weapon Buckles (ウエポンバックル, Uepon Bakkuru) to grant the use of a Form Raise Buckle's corresponding sidearm.[37]

Sara Sakurai (桜井 沙羅, Sakurai Sara) is Keiwa's older sister and a fan of Neon Kurama, and later Ace Ukiyo, who cares for Keiwa after their parents were killed in the crossfire of a previous DGP and were not revived in subsequent resets.[38][2][12]

After the monster is mortally injured by Kamen Riders Na-Go and Kyuun,[21][22] he allows the Dunkleosteus Jyamato to devour him so the monster can fully heal, with the Jyamato adopting Archimedel's form and personality as a result.[39]

But the Dunkleosteus Jyamato "Archimedel" grabs Daichi’s ID Core before Michinaga could destroy it.[34]

If a Jyamato Rider is defeated, another will take its place.[5] Furthermore, if a DGP player uses it for an extended period of time, the Jyamato Buckle will gradually turn them into a Jyamato.[6][29]
