Main characters

Ace Ukiyo

Ace Ukiyo (浮世 英寿, Ukiyo Ēsu) 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, Desire Deity), 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, Sutā Obu Za Sutāzu Obu Za Sutāzu), 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, Sōsei no Kami) 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, Gītsu Teiru) scarf. His primary Form Raise Buckles are Magnum and Boost, which allow him to assume Magnum Form (マグナムフォーム, Magunamu Fōmu) and Boost Form (ブーストフォーム, Būsuto Fōmu) 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, Magunamu Būsuto Fōmu) or Boost Magnum Form (ブーストマグナムフォーム, Būsuto Magunamu Fōmu). 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, Fībā Magunamu Fōmu) or the Boost Buckle to assume Fever Boost Form (フィーバーブーストフォーム, Fībā Būsuto Fōmu). In these forms, his Geats Tail evolves into the Fever Cross Tail (フィーバークロステール, Fībā Kurosu Tēru).
• 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, Būsuto Fōmu Māku Tsū) 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, Rēzā Būsuto Fōmu).
• 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, Būsuto Fōmu Māku Surī) 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, Kamen Raidā Gītsu Nain).

Four Aces

The Four Aces (4人の英寿, Yo-nin no Ēsu) 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, Chikara no Ēsu): 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, Chie no Ēsu): 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, Un no Ēsu): 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, Kokoro no Ēsu): 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, Kamen Raidā Gītsu Wan'nesu), 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.

Recurring characters

DGP

The Desire Grand Prix (デザイアグランプリ, Dezaia Guran Puri, DGP) 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, Dezasutā, Desire Star), 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, Jamato Guran Puri, JGP). 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, Gurando Endo), 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, Dezaia Doraibā) belt, which can combine with a personalized ID Core (IDコア, Ai Dī Koa) disc to transform them into a base Entry Form (エントリーフォーム, Entorī Fōmu) 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, with rare Jyamato offering stronger Raise Buckles.

The Supporters utilize Raise Riser Cards (レイズライザーカード, Reizu Raizā Kādo) in conjunction with the Laser Raise Riser (レーザーレイズライザー, Rēzā Reizu Raizā) 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, Burakku Reizu Raizā Kādo) to transform into a Jyamato-esque Premium (プレミアム, Puremiamu) warrior form.

The Game Master (ゲームマスター, Gēmu Masutā) possesses one to manage the DGP's system while Niramu possesses the second.

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, Kamen Raidā Gurea).

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.

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, Kamen Raidā Geizā). While transformed, he gains the use of five Dominion Ray (ドミニオンレイ, Dominion Rei) drones, which can create energy shields, for combat assistance.

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, Isaki Nana) and voiced by Yuka Terasaki (寺崎 裕香, Terasaki Yuka).

Suel

Suel (スエル, Sueru) 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, Kamen Raidā Rigado Omega): 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.

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, Shiriusu Kādo) in conjunction with the Vision Driver's successor, the Zillion Driver (ジリオンドライバー, Jirion Doraibā) 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, Kamen Raidā Rigado).

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. 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, 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. 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 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:

• 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4（フォー）0（ゼロ）X（エックス）, 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); the latter of which has an alternate Machine Gun Mode (マシンガンモード, Mashin Gan Mōdo) 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, Uepon) Raise Buckle based on the aforementioned firearm.
• Boost (ブースト, Būsuto): Grants increased mobility 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 perform 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 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, Būsuto Māku Tsū): 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, Bīsuto Mōdo) 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, Būsuto Māku Surī): 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Q（キュー）B（ビー）9（ナイン）, Gītsu Basutā Kyū Bī Nain), which can switch between Railgun Mode (レールガンモード, Rērugan Mōdo) and Blade Mode (ブレードモード, Burēdo Mōdo). Using the Boost MarkIII Buckle in its one-piece state grants the ability to materialize three fox tail-like energy whips and generate black holes while using it as the two-piece Boost MarkIX (ブーストマークIX, Būsuto Māku Nain) Buckle grants reality manipulation capabilities.
• 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 that is capable of dissolving the user's enemies into nothingness.
• Ninja (ニンジャ): Grants proficiency in ninjutsu and the use of the double-bladed Ninja Dueler (ニンジャデュアラー, Ninja Duarā) sword, which can switch between its one-piece Single Blade (シングルブレード, Shinguru Burēdo) and two-piece Twin Blade (ツインブレード, Tsuin Burēdo) modes.
• Monster (モンスター, Monsutā): Equips the user with the Monster Glove (モンスターグローブ, Monsutā Gurōbu) gauntlets and/or the Big Boot (ビッグブーツ, Biggu Būtsu) sabatons.

• Beat (ビート, Bīto): Grants sonokinesis 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. During the events of the crossover 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 Raise Buckle which can only be activated on the Desire Driver's right-hand side 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 an upgraded Fever Form (フィーバーフォーム, Fībā Fōmu), whose power level is increased two-fold without the use of the Revolve On function. Five copies of the Fever Slot Buckle were created by Girori to counter the Jyamato's increasing power.
• 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). Using 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 using both Command Twin Buckles at once after charging the Command Cannon Buckle with 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.
• Powered Builder (パワードビルダー, Pawādo Birudā): A right-hand side exclusive Raise Buckle that equips the user with the twin Arm Builder (アームビルダー, Āmu Birudā) manipulators on the front and back of the armor's body and can combine with one of three small-sized Gigant (ギガント, Giganto) Raise Buckles, which are stored in the left-hand side exclusive Gigant Container (ギガントコンテナ, Giganto Kontena) Buckle, to grant the use of a corresponding Gigant Weapon (ギガントウエポン, Giganto Uepon). This set of Raise Buckles first appears in the crossover film Kamen Rider Geats × Revice: Movie Battle Royale.
• Bujin Sword (ブジンソード, Bujin Sōdo): A two-in-one Raise Buckle created by Tsumuri from Keiwa's wish that grants umbrakinesis and the use of the Bujin (武刃, Warrior Sword) katana. Its right half serves as a primary base form while its left half can be replaced with other Raise Buckles.

In truth, Sara is transported and entrapped alongside other victims of Stage 2 parasite Jyamato inside the Tree of Knowledge (知恵の樹, Chie no Ki). While revived alongside their parents through Tsumuri granting Keiwa's wish to revive everyone killed in the DGP, she and her parents end up being killed again by Kamen Rider Tarbon.

After the monster is mortally injured by Kamen Riders Na-Go and Kyuun, 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.

The Dunkleosteus Jyamato, acting out on Archimedel's ideology, would make his presence known in the Desire Royale when he grabs Daichi's ID Core before Michinaga could destroy it.

The Jyamato (ジャマト, Jamato) are plant-based monsters based in a greenhouse within the mysterious Jyamar Garden and appear in the Jyamar Area (ジャマーエリア, Jamā Eria), where they are cultivated and fed broken ID Cores by Archimedel after they spawn. Initially containing the memories and embodying the desires of fallen DGP players, the Jyamato gradually evolve into stronger variants with the ability to mimic the fallen players' forms. Additionally, if the DGP players lose against the Jyamato, the Jyamar Area will become an extension of the Jyamar Garden. The Jyamato were originally created by the future people using mutant plants that they took from a ruined Earth.

Among the Jyamato sub-species are the Bishop Jyamato (ビショップジャマト, Bishoppu Jamato), the Knight Jyamato (ナイトジャマト, Naito Jamato), the Rook Jyamato (ルークジャマト, Rūku Jamato), the Pawn Jyamato (ポーンジャマト, Pōn Jamato) foot soldiers, the sea slug-like giant Slug Fortress Jyamato (スラグフォートレスジャマト, Suragu Fōtoresu Jamato), the Rafflesia-like giant Rafflesia Fortress Jyamato (ラフレシアフォートレスジャマト, Rafureshia Fōtoresu Jamato), and the Dunkleosteus Jyamato (ダンクルオステウスジャマト, Dankuruosuteusu Jamato).

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

After Ace awakened his power, he recreated the world with one of his rules stating that Jyamato should not exist though leftovers have remained even from past Grand Ends with said survivors being written off as folklore monsters; this time, Daichi bypasses that by hybridizing humans and Jyamato, turning himself into one while creating parasitic miniature Pawn Jyamato that can turn human hosts into Jyamato. While the Stage 1 parasite Jyamato can be safely removed from the host's body, Daichi makes a stranger batch while removing that design flaw. If the victims who were infected with Stage 2 parasite Jyamato were presumably killed, their bodies are transported and entrapped inside the Tree of Knowledge where Daichi could use their knowledge to fulfill his desire. After Daichi reforms to atone his crime for being a pawn for the DGP and both Kekera and Beroba, he mass-produces a serum to revive those who were infected by the Stage 2 parasite Jyamato can still be saved. As part of his atonement, ahead of Suel's final plan, Daichi transforms Jyamato into humanity's supporters.
