## Main characters
### Kamen Rider Revice

Kamen Rider Revice is the eponymous duo of Ikki Igarashi and his inner demon partner Vice whose arsenal revolves around Vistamps (バイスタンプ, Baisutanpu), a series of rubber stamp-like items reverse-engineered from the Giff Stamp (ギフスタンプ, Gifu Sutanpu) and designed to harness the power of inner demons as well as channel the human user's genetic memory. Utilizing the Rex (レックス, Rekkusu) Vistamp in conjunction with the Revice Driver (リバイスドライバー, Ribaisu Doraibā) belt, Ikki and Vice can transform into Kamen Riders Revi and Vice Rex Genome (レックスゲノム, Rekkusu Genomu) respectively. While transformed, Vice gains a physical form that is adorned with the Buddy Buckle (バディバックル, Badi Bakkuru) belt, which connects to Ikki's Revice Driver via the built-in Genome Receiver (ゲノムレシーバー, Genomu Reshībā). As Rex Genome, Ikki and Vice gain increased leg and tail strength respectively. They also share three sidearms: the Ohinbuster 50 (オーインバスター50（フィフティー）, Ōinbasutā Fifuti), which can switch between Gun Mode (ガンモード, Gan Mōdo) and Axe Mode (アックスモード, Akkusu Mōdo); the Gundephone 50 (ガンデフォン50（フィフティー）, Gandefon Fifuti), which can switch between Phone Mode (フォンモード, Fon Mōdo) and Gun Mode; and the Osutoderuhammer 50 (オストデルハンマー50, Osutoderuhanmā Fifuti), which can combine with the Ohinbuster 50 to form the Revicelasher (リバイスラッシャー, Ribaisurasshā) sword. As Ikki and Vice are separate halves of Revice's forms, they can use the Remix (リミックス, Rimikkusu) ability to fuse into an animal-like state based on their current form. Additionally, the duo possess several other Vistamps, each of which is based on a different animal, and their corresponding Genome (ゲノム, Genomu) forms are modeled after a different past Shōwa, Heisei, or Reiwa Kamen Rider.

* Kamakiri Genome (カマキリゲノム, Kamakiri Genomu): A Kamen Rider Gaim-themed auxiliary form accessed from the Kamakiri (カマキリ) Vistamp that grants Ikki and Vice the use of the bladed Kamakiric Arrow (カマキリックアロー, Kamakirikku Arō) bow and proficiency in Northern Praying Mantis respectively.

While Vice initially remains in his Rex Genome, he compensates with the Barid Shield (バリッドシールド, Bariddo Shīrudo), a DIY weapon he built from the by-products of Ikki's transformation.

#### Ikki Igarashi

Ikki Igarashi (五十嵐 一輝, Igarashi Ikki) is the oldest son of the Igarashi family who can become Kamen Rider Revi (仮面ライダーリバイ, Kamen Raidā Ribai). Originally, he was a promising soccer player who abandoned his career to live a normal life and help with the Igarashi family business out of guilt for accidentally injuring his friend Kōji Ikeyama (池山 浩二, Ikeyama Kōji), nicknamed "Zico", during high school. Additionally, he formed a contract with Vice to protect his family from Vail as a child, but repressed the memory. However, the Deadmans' threat on his family causes him to accept Fenix's offer to join them in their battle against the evil cult. Amidst their battles together, Ikki and Vice end up merging together, causing the former's repressed memories to resurface, and discover Ikki and his siblings are Giff's descendants. Furthermore, Ikki learns the contract he made with Vice as a child is slowly erasing his memories of those he considers family whenever he becomes Revi, though Vice sacrifices himself to prevent this. Ikki loses his memories of Vice as a result, though he rejoins the soccer team and resumes his normal life.
During the events of the crossover film Kamen Rider Geats × Revice: Movie Battle Royale, Ikki participates in the Desire Royale as a Desire Grand Prix (DGP) Kamen Rider, with his primary Form Raise Buckle being Beat.
Ikki Igarashi is portrayed by Kentaro Maeda (前田 拳太郎, Maeda Kentarō). As a child, Ikki is portrayed by Atsuki Morinaga (盛永 晶月, Morinaga Atsuki) in episodes 9-11 and 42 and Yurito Mori (森 優理斗, Mori Yurito) in episodes 25 and 42.

#### Vice

Vice (バイス, Baisu) is the benevolent yet mischievous and wisecracking inner demon who embodies Ikki's repressed desires and selfishness. As Ikki is the only person to perceive his presence initially, the latter's transformation allows Vice to become Kamen Rider Vice (仮面ライダーバイス, Kamen Raidā Baisu). Thanks to his contract with Ikki, Vice obtains a corporeal form, which he uses to assist and protect Ikki as their lives are linked and should Ikki die, he will also perish. Moreover, Vice has a habit of breaking the fourth wall. After Ikki acquires the Gundephone 50, Vice can enter its system, which allows him to communicate with people without transforming.
Late into the series, it is revealed that Vice first manifested during Ikki's childhood when Vail destroyed the first version of Shiawaseyu and formed a contract with the boy to protect Ikki's family. Ikki repressed the memory while Vice went dormant until the former acquires the Revice Driver in the present. Furthermore, Vice became a technological genius following his re-awakening, which he primarily uses to maintain Ikki's father, Genta's, desire to promote Shiawaseyu through online videos. Eventually, after Ikki loses all memory of his family, Vice decides to play the role of a villain and force Ikki to fight him in a suicidal gambit to restore his partner's memory with help from his host's family and their allies, among other people they had helped. Following his successful self-sacrifice, Vice is memorialized by Shiawaseyu painting a rubber duck with Vice's face to serve as the bathhouse's "guardian spirit" and Daiji rebranding the joint Fenix-Weekend organization as Blue Bird.
During the events of the crossover film Kamen Rider Geats × Revice: Movie Battle Royale, Vice is temporarily revived and participates in the Desire Royale as a DGP Kamen Rider, with his primary Form Raise Buckle being Monster.
Vice is voiced by Subaru Kimura (木村 昴, Kimura Subaru), who also portrays a fictionalized version of himself in episodes 30, 31, and 50.

### Kamen Riders Live and Evil

Kamen Riders Live and Evil are the duo of Daiji Igarashi and his inner demon Kagero, respectively, who usually share one body. Utilizing the Bat (バット, Batto) Vistamp in conjunction with the Two SiDriver (ツーサイドライバー, Tsū Saidoraibā) belt and the Two Side Weapon (ツーサイドウェポン, Tsū Saido Uepon), they can transform into their Rider forms, which are as follows:
* Kamen Rider Live (仮面ライダーライブ, Kamen Raidā Raibu): Daiji's Honduran white bat-themed Rider form accessed by using the Two Side Weapon in its Live Gun (ライブガン, Raibu Gun) mode. While transformed, he gains photokinesis.
* Kamen Rider Evil (仮面ライダーエビル, Kamen Raidā Ebiru): Kagero's brown long-eared bat-themed Rider form accessed by using the Two Side Weapon in its sword-like Evil Blade (エビルブレード, Ebiru Burēdo) mode. While transformed, he gains umbrakinesis.
If necessary, Daiji and/or Kagero can also use Ikki and Vice's Vistamps to assume varying Genomes, with the latter assuming dark Kamen Rider-themed forms, which are as follows:

** Kamen Rider Evilyty Live (仮面ライダーエビリティライブ, Kamen Raidā Ebiriti Raibu): The evolved form of Holy Live accessed from the Perfect Wing (パーフェクトウイング, Pāfekuto Uingu) Vistamp, which is created from the Holy Wing Vistamp, that grants a pair of Perfect Wings and the ability to freely switch between the Two Side Weapon's modes and summon a shadow-like copy of Kamen Rider Evil for combat assistance. If necessary, Kagero can assume control of the form.
* Kamen Rider Live Marvelous (仮面ライダーライブマーベラス, Kamen Raidā Raibu Māberasu) and Kamen Rider Evil Marvelous (仮面ライダーエビルマーベラス, Kamen Raidā Ebiru Māberasu): The respective ultimate forms of Daiji and Kagero accessed from the Mega Bat (メガバット, Mega Batto) Vistamp in conjunction with the Revice Driver that grants the latter a separate body. While transformed, Daiji and Kagero wield the Ohinbuster 50 and Revicelasher respectively. These forms appear exclusively in the V-Cinema Revice Forward: Kamen Rider Live & Evil & Demons.
Daiji Igarashi and Kagero are portrayed by Wataru Hyuga (日向 亘, Hyūga Wataru).

#### Daiji Igarashi

Daiji Igarashi (五十嵐 大二, Igarashi Daiji) is Ikki's athletic younger brother and an honor student who volunteers to work for Fenix as a squad leader and the intended recipient of the Revice Driver before his brother, Ikki, gets ahold of it. Following the latter event and Hiromi Kadota's failed attempt to use the Revice Driver, Daiji is left traumatized. Although Daiji holds no ill intent towards Ikki, the former's desire to stand out stems from a mix of jealousy and an inferiority complex towards the latter, resulting in his own inner demon, Kagero, immediately possessing his body shortly before Daiji receives new Rider equipment from George Karizaki. Kagero attempts to use Daiji to kill Ikki and Vice, but Daiji becomes aware of Kagero's presence and initially struggles to keep the demon from hurting his family until he realizes that they have always looked up to him, allowing him to regain control of his body. Upon discovering he and his siblings are descendants of Giff and being separated from Kagero, Daiji settles his differences with the latter in combat, with Kagero seemingly dying in the process. This absence causes a detrimental effect on Daiji's sense of self as he is slowly corrupted by his own ideals. Following his colleague Akemi Mikoshiba's death, he betrays his family and allies to avenge her. To this end, he kills Akaishi, only to take his role as Giff's protector and attempt to form a pact with the demon, only to be thwarted by Vice. With Hiromi Kadota's help, Daiji realizes the error of his ways and reunites with Kagero. After helping Vice restore Ikki's memories, Daiji leads the merged Fenix-Weekend organization, Blue Bird, in the former's memory.
As a child, Daiji is portrayed by Atsuki Yamada (山田 暖絆, Yamada Atsuki).

#### Kagero

Kagero (カゲロウ, Kagerō) is Daiji's malevolent and calculative inner demon who embodies his host's jealousy and inferiority complex towards Ikki and trauma from overusing George Karizaki's Vistamp-based Rider System. At the time of his awakening, Kagero briefly possesses Daiji's body and secretly steals a Vistamp from Fenix. When George notices Kagero's presence within Daiji's body, he allows Daiji to transform into a Kamen Rider for the first time, allowing Kagero to completely possess his host's body. After the demon joins Deadmans, Fenix's executives and Daiji discover what happened and the former bar the latter's family from knowing until Kagero reveals his presence to them. While attempting to eliminate Ikki, Kagero discovers George used him to help Daiji regain control of his body before Kamen Rider Revice defeat him. Despite this, Kagero is able to retake control when his host becomes incapacitated. Gradually weakening after the Igarashi siblings discover their connection to Giff, Kagero acquires the Crow Vistamp and uses it to separate himself from Daiji so they can settle their differences in a duel. Daiji emerges victorious, with a mortally wounded Kagero giving him the Vistamp before entering it in order to heal. Kagero's absence causes Daiji to become unstable and more reckless and adopt the former's warped outlook on justice until Daiji eventually sees the error of his ways, fully healing Kagero.
During the events of the crossover film Kamen Rider Geats × Revice: Movie Battle Royale, Kagero and Daiji’s encounter with Keiwa foreshadows the DGP player’s downfall at the hands of his inner demon, which ultimately occurs during the early rounds of “Creation” DGP tournament, much to their fears.

### Sakura Igarashi

Sakura Igarashi (五十嵐 さくら, Igarashi Sakura) is Ikki and Daiji's younger sister, a high school student, and a karateka. Following Kagero's awakening and possession of Daiji, she develops a grudge against Deadmans for ruining her family and develops a rivalry with cult member, Aguilera. In pursuit of joining her brothers in combat, Sakura receives her own Rider equipment from a mysterious individual, later revealed to be an agent from the secret organization, Weekend. Following Giff's defeat and Vice's sacrifice, she plans to enter medical school.
Utilizing the Cobra (コブラ, Kobura) Vistamp in conjunction with the Libera Driver (リベラドライバー, Ribera Doraibā) belt, Sakura can transform into Kamen Rider Jeanne (仮面ライダージャンヌ, Kamen Raidā Jan'nu).

As a manifestation of the latter's weaknesses and childhood past-self, the former lacks her partner's combat capabilities but can be transformed into weapons for Sakura to use. While normally non-combative compared to Vice and Kagero, Lovekov can lash out at humans while being influenced by Giff's aura. Eventually growing tired of being put on the sidelines, Lovekov tries to evolve so she can fight alongside Sakura. Following her evolution at the same time after defeating Giff together with her siblings and allies, Lovekov can finally speak full sentences outside Sakura's mind.
During the events of the film Kamen Rider Revice the Movie: Battle Familia, Lovekov temporarily gains a teenage female humanoid form.

Seven years later, following Vail's attack on the first Shiawaseyu, Yukimi and one of her husband's friends, Shōzō Irabu and Masumi Karizaki, secretly kept in touch while ensuring her children never learned of the incident until they became Kamen Riders and Vail returned in the present.

Following this, Vail emerged and murdered Genta's parents, leading to the latter joining NOAH to find the demon. Amidst his quest, he met and fell in love with Yukimi and received help from Masumi and Shōzō Irabu to leave NOAH, only to learn NOAH and Vail were involved in his parents' murder in the process. After Genta chose to start a family with Yukimi, Vail mounted a failed attempt on their lives before Masumi extracted the demon and sealed him in the Demons Driver. As a result, Genta lost his memories as Shiranami, but became able to survive without a heart as it was extracted alongside Vail. In the present, Hideo Akaishi helps Vail break free of the Demons Driver and re-possess Genta, forcing him into hiding with Irabu to protect his family while he struggles to suppress Vail. Before he does so, Genta entrusts his children to right his past wrongs and protect Yukimi in his stead in the event he sacrifices himself to stop Vail. In response to Giff's invasion, Genta volunteers to undergo a cell transfusion so the Karizakis can create the Giffard Rex Vistamp with the intention of sacrificing himself, though Genta survives the procedure and goes on to settle his rivalry with Vail.
While under Vail's control, Genta utilizes the Kabuto (カブト) Vistamp in conjunction with the Vail Driver (ベイルドライバー, Beiru Doraibā) belt to transform into Kamen Rider Vail (仮面ライダーベイル, Kamen Raidā Beiru).

Following his revival, Giff destroys the Sky Base, killing most of Fenix's operatives. The survivors transfer their operations to an urban development site called ARARAT in the hopes of developing inner demon removal stamps, only to create stamps that have the opposite effect and strengthen Giff. Following Akaishi's demise, Giff's proper defeat, and Vice's sacrifice, Daiji takes command of Fenix's remnants and merges them with that of Weekend's to form Blue Bird (ブルーバード, Burū Bādo).

#### Hideo Akaishi

"Hideo Akaishi" (赤石 英雄, Akaishi Hideo) is a millennia-old Aztec king who once led a kingdom in opposition to Giff before his people were wiped out. Akaishi formed a contract with Giff to spare the rest of humanity from the latter's wrath in exchange for serving as his emissary. The pact resulted in Akaishi becoming an immortal with a drastically slow aging process and the ability to become a Giffdemos at the cost of a deformed right hand, which he covers with a glove. He would later go on to become a NOAH researcher and a member of the US government's Department of Defense in order to secretly manipulate them into improving Giff's potential. Twenty-five years prior to the series, he and his NOAH superior, Agariyama, worked with Vail to murder Genta's parents and use him in the organization's experiments until Genta, among others, leave NOAH. Following this and NOAH's destruction, Akaishi found Vail in the Demons Driver and stole Giff's casket to enact a new plan to facilitate Giff's revival. While publicly founding Fenix and becoming its director-general to cover his activities, he also secretly founded Deadmans and entrusted the newly recruited Orteca to serve as the cult's public face and watch over Giff's casket in his stead.
In the present, as Genta's offspring become Kamen Riders, Akaishi grants permission for the Demons Driver's field deployment to manipulate Hiromi Kadota and Orteca into eventually freeing Vail and sacrificing Orteca to revive Giff. Following Kagero's death, Akaishi manipulates Daiji into unknowingly disrupting his spiritual balance and defect to his cause. After making an enemy out of Hikaru Ushijima and being defeated by Kamen Rider Ultimate Revice, Akaishi sacrifices his immortality in exchange for Giff reviving him as a red Gigademos, deeming humanity beyond redemption and resolving to kill everyone. However, he is defeated by Hikaru and killed by a vengeful Daiji.

### Deadmans

The Demon-Worshipping Organization Deadmans (悪魔崇拝組織デッドマンズ, Akuma Sūhai Soshiki Deddomanzu) is a demon cult and splinter faction of the military organization, NOAH, founded by Hideo Akaishi that has been active for fifty years and seek to revive the progenitor of all demons, Giff, by gathering six Gifftex (ギフテクス, Gifutekusu), or Phase 3 (フェーズ3, Fēzu Surī), Deadmen for a ritual sacrifice. To do so, they provide people with Vistamps to form a contract with their inner demon, manifest the latter as a Phase 1 Deadman, merge with it to achieve its Phase 2 form and fully integrate with it to achieve its Phase 3 form. Compared to the other phases, humans that become Gifftex Deadmen run the risk of being killed if they are defeated in combat, though they can be separated by Kamen Rider Revice's Barid and Volcano Rex Genome's powers. However, if a Deadmans member who was originally chosen to become a sacrifice for Giff's revival but became a Phase 3 Deadman instead, they are deemed incompatible as a sacrifice. Additionally, Deadmans members can also use Giff Junior Vistamp on the weakest of their followers to create Giff Junior (ギフジュニア, Gifu Junia) foot soldiers to aid them in battle. The Deadmans was initially based in the Deadmans Base (デッドマンズベース, Deddomanzu Bēsu), a repurposed airship with a nightclub-like interior, before it was destroyed by Fenix.

#### Giff

Giff (ギフ, Gifu) is the mysterious progenitor of all demons who thrives on negative energy and came to Earth several millennia prior to feed off the darkness of humanity, but came to despise them for those who fear him and abuse his abilities for selfish ends. Convinced by Hideo Akashi to spare humanity, Giff made him and Azuma loyal followers to manipulate humanity to ensure his conquest of Earth is unopposed. Giff then entered into a deep sleep within a sarcophagus-like chrysalis called Giff's Sarcophagus (ギフの棺, Gifu no Hitsugi) and arranged for NOAH to recover it fifty years prior to the series. After the organization fell, Akaishi retrieved the casket and entrusted it to a NOAH splinter faction called Deadmans and its leader Orteca, who seek to revive Giff via a ritual involving six Gifftex (ギフテクス, Gifutekusu) Deadmen and a designated sacrifice. While the Igarashi siblings disrupt the ritual and Fenix recovers the sarcophagus in the present, Giff absorbs the remains of the Deadmen and Gifftarians that the Igarashi siblings defeated over the course of their battles against the Deadmans. After bringing Orteca into his private dimension, which is Giff's metaphysical stomach where those sacrificed to him end up, Giff fully revives into his true form.
After Giff pulls Vice into his dimension, he adjusts his plans to exterminate all of humanity save for the Igarashi siblings, who he considers family, before Ultimate Revice and Evilyty Live temporarily seal him within his dimension. Upon returning, Giff produces parasites from his cocoon and uses them to take over humanity's inner demons, with an enthralled Vice by his side. However, Vice destroys his sarcophagus to remove the demon's invulnerability before the Igarashi family's Kamen Riders destroy Giff, whose eyes end up in George's possession.
Giff is voiced by Kazuhiko Inoue (井上 和彦, Inoue Kazuhiko).

### Kamen Rider Demons

Kamen Rider Demons (仮面ライダーデモンズ, Kamen Raidā Demonzu) is a moniker used by those who utilize the Spider (スパイダー, Supaidā) Vistamp in conjunction with the Demons Driver (デモンズドライバー, Demonzu Doraibā) belt, which contains Vail and Masumi Karizaki originally intended to be reverse-engineered from the Vail Driver using NOAH's resources twenty-five years prior to the series before Fenix completed it in the present. Due to prolonged usage of the belt, Vail is eventually able to break free, though he maintains his connection to the Demons Driver.
While transformed, the user can produce Demon String (デモンストリング, Demon Sutoringu) for multiple purposes as well as stick to walls and ceilings. Using Shōwa and Heisei Kamen Rider-themed Vistamps, they can assume varying Genomix (ゲノミクス, Genomikusu) forms, which change and enhance part of their body. With incompatible users, the demon will only transform for short periods of time, limit them to one Genomix, and feed on their life force, which physically ages them at an accelerated rate as a side effect and causes them to develop an addiction to the Demons Driver's power. With compatible users, they do not suffer side effects and are able to use multiple Genomixes at once depending on Vail's mood. Additionally, users who already possess an inner demon are immune to Vail's powers, though said demon will be awakened following contact with the Demons Driver.
* Batta Genomix (バッタゲノミクス, Batta Genomikusu): A Kamen Rider 1-themed auxiliary form accessed from the Batta (バッタ) Vistamp that grants a pair of Demon Bottom Higher (デモンボトムハイアー, Demon Botomu Haiā) legs.

* Condor Genomix (コンドルゲノミクス, Kondoru Genomikusu): A Kamen Rider Joker-themed auxiliary form accessed from the Condor (コンドル, Kondoru) Vistamp that grants a pair of Demon Rumble Joker (デモンランブルジョーカー, Demon Ranburu Jōkā) wings.
* Scorpion Genomix (スコーピオンゲノミクス, Sukōpion Genomikusu): A Kamen Rider X-themed auxiliary form accessed from the Scorpion (スコーピオン, Sukōpion) Vistamp that grants the use of the Demon Ridol Stinger (デモンライドルスティンガ, Demon Raidoru Sutinga) tail.

After George upgrades the Demons Driver to counteract Vail's connection to it and make it safer to use by making the user's inner demon power it, a user can utilize the Kuwagata (クワガタ) Vistamp instead of the Spider Vistamp to transform into Kamen Rider Over Demons (仮面ライダーオーバーデモンズ, Kamen Raidā Ōbā Demonzu). While transformed, they can use the right shoulder-mounted O Wingal Shade (Oウインガルシェード, O Uingaru Shēdo) mantle to fly while maintaining their Genomixes, though overuse of these will degrade the user's compatibility and awaken their inner demon over time.
Following Hikaru's successful transformation into Over Demons, George mass-produces more finalized Demons Drivers along with variants of the Spider and Kuwagata Vistamps to aid Hiromi in forming the Kamen Rider Demons Corps. (仮面ライダーデモンズ軍団, Kamen Raidā Demonzu Gundan), consisting of Kamen Rider Demons Trooper α (仮面ライダーデモンズトルーパーα, Kamen Raidā Demonzu Torūpā Arufa) and Kamen Rider Demons Trooper β (仮面ライダーデモンズトルーパーβ, Kamen Raidā Demonzu Torūpā Bēta) soldiers respectively.

To achieve his dream, he eventually joined Fenix and attempts to use the Revice Driver despite not having the proper training, only to be demoted to squad leader when his inner demon ran amok. After Daiji is possessed by his inner demon Kagero, Hiromi is granted use of the Demons Driver despite not being its intended user. Following the revelation of his superior Wakabayashi being murdered by the Chameleon Deadman, Hiromi succeeds him as a new commander of Fenix. However, Hiromi soon learns the truth behind the Demons Driver and of a conspiracy within Fenix, transforming one final time to aid in Deadmans' leader, Orteca's, capture before resigning from Fenix and revealing what he learned to the Igarashi siblings.

While Hiromi survived, he feigned amnesia and returned to his mother in their hometown to recover. Upon learning of what seemingly happened, his allies work to recover his memories until he reveals the truth and, with aid from Wakabayashi's spirit, rejoins them to face Giff by forming and taking command of the Kamen Rider Demons Corps and briefly re-assuming the mantle of Kamen Rider Demons to save Daiji from himself. Following Giff's death and Vice's sacrifice, Hiromi joins Fenix's successor organization, Blue Bird.

* Komodo Dragon Genomix: A Kamen Rider Ryuki-themed auxiliary form accessed from the Komodo Dragon Vistamp that equips Hiromi with the Komodo Dragonic Heat.
In the Beyond Generations side novel, which takes place in a dystopian future in the year 2071, Hiromi retires from being a Fenix officer and became a farmer when Diablo and his army of demons invaded Earth.

Orteca initially manipulates Aguilera into believing she is the cult's leader and Giff's bride while posing as her right hand. When he reveals the truth however, she transforms herself into a Deadman and leaves the cult, forcing Orteca to alter his plans and restructure Deadmans. Despite being defeated and separated from his Deadman form by Kamen Rider Revice and Giff subsequently absorbing his Deadman essence, Orteca allows himself to be captured by Fenix so he can trade the Giff Stamp to Akaishi for the Demons Driver, escaping as the new Demons. While Vail exploits Orteca to break free from the Demons Driver, he allows Orteca to continue using his power until they are defeated by Kamen Rider Holy Live, after which Orteca abandons Vail and retrieves the Anomalocaris Proto Vistamp while committing human sacrifices to hasten Giff's revival until he is defeated by Kamen Rider Revice and devoured by Giff. Months later, Orteca is freed by Kamen Riders Ultimate Revice and Evilyty Live and promptly arrested by Weekend.
Orteca utilizes his personal Daiouika Proto Vistamp to transform into his Daiouika Deadman (ダイオウイカ・デッドマン, Daiōika Deddoman) form, which is armed with the umbrella-like Paranegro (パラネグロ, Paraneguro) sword. After losing the Demons Driver, he uses the Anomalocaris Proto Vistamp and the Giff Stamp to absorb Giff and transform into his Anomalocaris Deadman (アノマロカリス・デッドマン, Anomarokarisu Deddoman) form, which is also armed with the Paranegro.
During the events of the film Kamen Rider Revice the Movie: Battle Familia, Orteca cooperates with George's plan to use the former and another Chimera Driver to break through the barrier surrounding Area 666 in exchange for a reduced sentence.

George is a fan of Kamen Riders, especially those of the Heisei era, and designs Fenix's Rider equipment with them as inspiration. As a child, he unknowingly received Masumi's inner demon, Chic.
After Daiji defeats Orteca and Vail, George retrieves the Demons Driver and uses it to temporarily become the third Kamen Rider Demons, resisting the belt's temptation and unknowingly awakening Masumi's inner demon in the process. Following this, George upgrades the belt to work in conjunction with the Kuwagata Vistamp in order to transform into Kamen Rider Over Demons, stabilize it, and mass-produce the belt, only for Hideo Akaishi to break his arm. In response, George gives the Over Demons equipment to Hikaru Ushijima per the latter's request before successfully mass-producing the Demons Driver and entrusting the copies to Hiromi so he can form the Kamen Rider Demons Corps. Due to the varying crises he and his allies have faced, George moves in with the Igarashi family while his arm heals.
Following Masumi's passing and Giff's defeat, George resolves to create a new Rider System that does not need inner demons to power it due to being unable to reconcile with his father in time and while under Chic's influence. As a result, he creates the Chimera Driver during the events of Birth of Chimera and Kamen Rider Revice the Movie: Battle Familia before a freed Chic steals the belt and modifies it with one of Giff's eyes. George replicates Chic's modifications to create the Juuga Driver (ジュウガドライバー, Jūga Doraibā) belt to use in conjunction with the Juuga (ジュウガ, Jūga) Vistamp he engineered from Revice's Vistamps to become Kamen Rider Juuga (仮面ライダージュウガ, Kamen Raidā Jūga) and attack other demon-based Riders to prove his tech's superiority over them and his father until he learns Masumi did cherish him and used George's childhood drawings as the basis for the Vistamp technology.
In an alternate timeline depicted in the crossover film Kamen Rider: Beyond Generations, an elderly George goes into hiding after Diablo conquered Earth and creates the Cyclotron Driver to alter the past to avert this future from occurring. In addition to gaining Ryunosuke's help to get to the year 2021, George also uses his tablet to turn the time-displaced Vice, Daiji, Sakura, Touma Kamiyama, Rintaro Shindo, and Yuri into Clone Riders (クローンライダー, Kurōn Raidā) to defend Ryunosuke's body from Diablo's army of Devil Riders.
