Main characters
Takumi Inui
Takumi Inui (乾 巧, Inui Takumi) is a mysterious loner who became the Wolf Orphnoch (ウルフオルフェノク, Urufu Orufenoku) after being hit by a car when he was a child. He attempted to use his newfound powers to protect people, but his failure to save the Ryusei School reunion from Kitazaki and an implanted memory that made him believed he was the culprit forced Takumi to isolate himself from others out of fear of betraying them and forget that he became an Orphnoch. By chance, he encounters Mari Sonoda and follows her under the belief that the Faiz Gear case she was carrying was stolen from him days earlier. As a result, he reluctantly becomes involved in her crusade to fight the Orphnochs as Kamen Rider Faiz. Amidst conflicts with Masato Kusaka and Yuji Kiba, Takumi accepts his role as Faiz and joins the latter in protecting humans. Eventually, Takumi remembers his true nature as an Orphnoch and learns the truth behind the Ryusei School massacre before settling his rivalry with Kiba while defeating the Arch Orphnoch together.
As the Wolf Orphnoch, Takumi possesses increased power compared to sired and most original Orphnochs and superhuman speed and agility. As Kamen Rider Faiz, he utilizes the SB-555P Faiz Phone (SB-555P ファイズフォン, SB-555P Faizu Fon) in conjunction with the SB-555B Faiz Driver (SB-555B ファイズドライバー, SB-555B Faizu Doraibā) belt to transform. While transformed, he can perform Exceed Charge (エクシードチャージ, Ekushīdo Chāji) finishers and wields a variety of gadgets from the Faiz Gear, such as the SB-555L Faiz Pointer (SB-555L ファイズポインター, SB-555L Faizu Pointā) flashlight that he can use in Kick Mode (キックモード, Kikku Mōdo) to perform the (Axel) Crimson Smash ((アクセル) クリムゾンスマッシュ, (Akuseru) Kurimuzon Sumasshu) Exceed Charge, the SB-555C Faiz Shot (SB-555C ファイズショット, SB-555C Faizu Shotto) digital camera that he can use in Knuckle Mode (ナックルモード, Nakkuru Mōdo) to perform the (Axel) Grand Impact ((アクセル) グランインパクト, (Akuseru) Guran Inpakuto) Exceed Charge, and the SB-555H Faiz Edge (SB-555H ファイズエッジ, SB-555H Faizu Ejji) sword that he can use to perform the (Axel) Sparkle Cut ((アクセル) スパークルカット, (Akuseru) Supākuru Katto) Exceed Charge. The SB-555H Faiz Edge also doubles as a handlebar for his personal vehicle, the SB-555V Auto Vajin (SB-555V オートバジン, SB-555V Ōto Bajin) motorcycle, which can transform into a support robot to aid him in combat. Additionally, certain gadgets allow Takumi to assume stronger forms, which are as follows:
Axel Form (アクセルフォーム, Akuseru Fōmu): Takumi's super form accessed from the stopwatch-like SB-555W Faiz Axel (SB-555W ファイズアクセル, SB-555W Faizu Akuseru) brace in Axel Mode (アクセルモード, Akuseru Mōdo) that enhances his physical attacks, grants superhuman speed, and allows him to perform enhanced versions of his original Exceed Charges with the appropriate gadgets for 10 seconds.
Blaster Form (ブラスターフォーム, Burastā Fōmu): Takumi's ultimate form accessed from the SB-555T Faiz Blaster (SB-555T ファイズブラスター, SB-555T Faizu Burastā), which doubles as the SB-555V Auto Vajin's trunk, in conjunction with the SB-555P Faiz Phone that equips him with the Photon Field Floater (フォトンフィールドフローター, Foton Fīrudo Furōtā) jetpack, whose thrusters double as the twin shoulder-mounted Bloody Cannons (ブラッディ・キャノン, Buraddi Kyanon), and grants significantly increased power via photon energy. He can also use the SB-555T Faiz Blaster in either its shotgun-like Photon Buster Mode (フォトンバスターモード, Foton Basutā Mōdo) to perform the Photon Buster (フォトンバスター, Foton Basutā) Exceed Charge or its sword-like Photon Breaker Mode (フォトンブレイカーモード, Foton Bureikā Mōdo) to perform the Photon Breaker (フォトンブレイカー, Foton Bureikā) and Super Strengthen Crimson Smash (超強化クリムゾンスマッシュ, Chō Kyōka Kurimuzon Sumasshu) Exceed Charges.
During the events of the V-CinemaKamen Rider 555 20th: Paradise Regained, Takumi utilizes the SB-555P20 Faiz Phone 20 Plus (SB-555P20 ファイズフォン20 Plus, SB-555P20 Faizu Fon Tuenti Purasu) in conjunction with the SB-555BN Faiz Driver Next (SB-555BN ファイズドライバーNEXT, SB-555BN Faizu Doraibā Nekusuto) belt to transform into Kamen Rider Next Faiz (仮面ライダーネクストファイズ, Kamen Raidā Nekusuto Faizu), which also has access to Axel Form.

Mari Sonoda
Mari Sonoda (園田 真理, Sonoda Mari) is a member of the Ryusei School who strives to see the good in others and dreams of becoming a beautician. Though she was sent the Faiz Gear and SB-555V Auto Vajin by their foster father, Hanagata, she was unable to use them. After seeing Takumi Inui successfully use the equipment, she insists he accompany her in fighting the Orphnochs.
In an alternate timeline depicted in the film Kamen Rider 555: Paradise Lost, Sonoda serves as the leader of the Human Liberation Army (人間解放軍, Ningen Kaihō-gun), a guerilla force of anti-Orphnoch resistance fighters and the last known bastion of human resistance in an Orphnoch-dominated world.
During the events of the V-Cinema Kamen Rider 555 20th: Paradise Regained, Mari becomes the Wildcat Orphnoch (ワイルドキャットオルフェノク, Wairudokyatto Orufenoku) due to the activation of her implanted Orphnoch DNA by Smart Brain.

Yuji Kiba
Yuji Kiba (木場 勇治, Kiba Yūji) is a friendly and polite young man who became the Horse Orphnoch (ホースオルフェノク, Hōsu Orufenoku) after dying in a car crash and ending up in a comatose state for two years. Upon awakening, Yuji discovers his uncle sold his family's company and his girlfriend Chie Morishita left him for his cousin Kazuaki Kiba. After murdering Kazuaki and Morishita in anger, Yuji turns to Smart Brain for protection, only to learn of their tactics and resolve to fight them and protect humans using his Orphnoch powers. In pursuit of this goal, he befriends Yuka Osada and Naoya Kaido, but forms a rivalry with Takumi Inui due to a misunderstanding until they learn each other's true identities and intentions. Upon learning of Yuka's death, who he believed was killed by the police, Yuji kills Masato Kusaka for the Kaixa Gear, discards his ideals, and eventually replaces Kyoji Murakami as the chairman of Smart Brain. However, Yuji's humanity is restored following a final battle with Takumi and he later sacrifices himself to help him defeat the Arch Orphnoch.
In an alternate timeline depicted in the film Kamen Rider 555: Paradise Lost, Yuji maintained his desire to protect humans from other Orphnoch until Osada and Naoya are killed by the Elasmotherium Orphnoch and Yuji is manipulated by Smart Brain into believing humanity had betrayed him. Accepting the Orga Gear, one of two "perfect" Rider Gears created by Smart Brain that can only be used by Orphnoch, he agrees to serve them as Kamen Rider Orga (仮面ライダーオーガ, Kamen Raidā Ōga) and fights Takumi, who eventually defeats Yuji and shows him the error of his ways. Yuji subsequently sacrifices himself to weaken the Elasmotherium Orphnoch so Takumi can kill it.
As the Horse Orphnoch, Yuji wields a sword and shield and can transform further into a centaur-like Gallop Mode (疾走態, Shissō-tai). In the series finale and Paradise Lost, Yuji evolves into the Horse Orphnoch's Raging Mode (激情態, Gekijō-tai), gaining increased power. As Kamen Rider Orga, he utilizes the SB-000P Orga Phone (SB-000P オーガフォン, SB-000P Ōga Fon) in conjunction with the SB-000B Orga Driver (SB-000B オーガドライバー, SB-000B Ōga Doraibā) belt to transform. While transformed, he wields the SB-000S Orga Stlanzer (SB-000S オーガストランザー, SB-000S Ōga Sutoranzā) sword, which can switch between Dagger Mode (短剣モード, Tanken Mōdo) and Longsword Mode (長剣モード, Chōken Mōdo); the latter of which allows him to perform the Orga Stlash (オーガストラッシュ, Ōga Sutorasshu) Exceed Charge.
Yuji Kiba was portrayed by the late Masayuki Izumi (泉 政行, Izumi Masayuki).
Masato Kusaka
Masato Kusaka (草加 雅人, Kusaka Masato) is a student of the Ryusei School and childhood friend of Mari Sonoda, having fallen in love with her after she saved him from bullies, and failed to attend the Ryusei School reunion. After learning of the massacre, he vowed to destroy the Orphnochs with extreme prejudice and wipe his hands of the blood he essentially spilled that night. To this end, he acquired the Kaixa Gear, which can only be used by Orphnochs or humans implanted with a sufficient amount of Orphnoch DNA, and became Kamen Rider Kaixa (仮面ライダーカイザ, Kamen Raidā Kaiza), using his implanted Orphnoch DNA to survive the belt's fatal side effects longer than its past human users and developing a rivalry with Takumi Inui. Eventually, Masato begins to suffer from the Kaixa Gear's side effects before he is killed by Yuji Kiba.
In an alternate timeline depicted in the film Kamen Rider 555: Paradise Lost, Masato is killed by Kamen Rider Psyga.
During the events of the V-Cinema Kamen Rider 555 20th: Paradise Regained, an android modeled after Masato and programmed to kill alumni of the Ryusei School who became Orphnochs is sent by Smart Brain, only to be destroyed by Takumi Inui as Kamen Rider Faiz. A second android Masato takes the android Kitazaki's place after the latter's destruction.
Masato utilizes the SB-913P Kaixa Phone (SB-913P カイザフォン, SB-913P Kaiza Fon) in conjunction with the SB-913B Kaixa Driver (SB-913B カイザドライバー, SB-913B Kaiza Doraibā) belt to transform into Kamen Rider Kaixa. While transformed and similarly to users of the Faiz Gear, he can perform Exceed Charges and wields a variety of gadgets from the Kaixa Gear, such as the SB-913B Kaixa Pointer (SB-913B カイザポインター, SB-913B Kaiza Pointā) binoculars that like the SB-555L Faiz Pointer can be used in Kick Mode for him to perform the Gold Smash (ゴルドスマッシュ, Gorudo Sumasshu) Exceed Charge and the SB-913C Kaixa Shot (SB-913C カイザショット, SB-913C Kaiza Shotto) digital camera that like the SB-555C Faiz Shot can be used in Knuckle Mode for him to perform his own version of the Grand Impact. Unlike Faiz, Masato also wields the SB-913X Kaixa Blaygun (SB-913X カイザブレイガン, SB-913X Kaiza Bureigan), which can switch between Gun Mode (ガンモード, Gan Mōdo) and Blade Mode (ブレードモード, Burēdo Mōdo); the latter of which allows him to perform the Kaixa Slash (カイザスラッシュ, Kaiza Surasshu) Exceed Charge. His personal vehicle is the SB-913V Side Basshar (SB-913V サイドバッシャー, SB-913V Saido Basshā) motorcycle/sidecar combination, which can convert into a walker-esque support mecha.

Recurring characters
Orphnochs
Orphnochs (オルフェノク, Orufenoku)[a] are humans reborn as gray animal or plant-themed zombie-like monsters who were meant to be the next stage in human evolution. Two types seen throughout the series are "original" Orphnochs, dead humans who are subsequently resurrected as monsters, and "sired" Orphnochs, humans who survive being attacked by an Orphnoch similarly to vampires and werewolves, though they are weaker than originals. While both types are capable of switching between their human and Orphnoch forms, they suffer from a genetic flaw that causes them to eventually and inevitably disintegrate due to the human body being unable to withstand such a rapid evolution, with the use of Rider Gears accelerating the process. Additionally, there exists a third type called "evolved" Orphnochs, who are genetically perfect and significantly more powerful, but lack the ability to turn back into their human forms and can only reach this stage with assistance from the Arch Orphnoch.
All Orphnochs share superhuman abilities and senses as well as the ability to produce tendrils capable of killing humans or converting them into more Orphnochs. Furthermore, they are capable of withstanding conventional firearms, with some capable of withstanding attacks by Rider Gear users.
In an alternate timeline depicted in the film Kamen Rider 555: Paradise Lost, Orphnochs were able to retain the use of their human forms while adapting away the genetic flaw that shortened their life spans after overthrowing humanity as the dominant species on Earth.
Yuka Osada
Yuka Osada (長田 結花, Osada Yuka) is a teenage girl who was bullied by her younger sister, who their parents favored over her, and other girls from her school and basketball team. The emotional stress from this leads to her falling down snow-covered stairs, reviving as the Crane Orphnoch (クレインオルフェノク, Kurein Orufenoku), and slaughtering her sister and the basketball team. Following this, she meets Yuji Kiba and joins him in protecting humans, though she occasionally and secretly kills people she deems "bad guys". Throughout the series, she exchanges texts with Keitaro Kikuchi, eventually developing a semi-romantic relationship with him along the way, and developed a crush on Naoya Kaido, though he does not reciprocate. Near the end of the series, she is mortally wounded by the Bat Orphnoch and killed by Saeko Kageyama.
In an alternate timeline depicted in the film Kamen Rider 555: Paradise Lost, Osada joins Yuji and Kaido in proving to the Human Liberation Army that they were on their side. However, the trio fall into a Smart Brain trap, during which Osada and Kaido are killed by the Elasmotherium Orphnoch.

In his younger years, Kaido played the guitar, but was sabotaged by his teacher, who destroyed his motor skills in his left hand, forcing him to abandon music. After struggling with his nature as an Orphnoch, Kaido lives with Yuji and Osada despite not sharing their desire to protect humans. Throughout the series, Kaido sides with Smart Brain, becoming Kamen Rider Faiz on one occasion and commander of their Riotroopers on a separate occasion, but his conscience ultimately stops him from committing heinous acts at the last second. Following Osada and Yuji's deaths, Kaido reintegrates into human society.
In an alternate timeline depicted in the film Kamen Rider 555: Paradise Lost, Kaido joins Yuji and Osada in proving to the Human Liberation Army that they were on their side, only to fall into a Smart Brain trap and come under attack by the Elasmotherium Orphnoch.

Near the end of the series, the grasshopper-like Arch Orphnoch (アークオルフェノク, Āku Orufenoku), also known as the Orphnoch King, begins to awaken inside Teruo as it uses the boy's shadow to consume other Orphnochs and mature. Upon awakening and possessing Teruo's body, the Arch Orphnoch battles Takumi Inui and Yuji Kiba until the latter sacrifices himself to help the former defeat the Arch Orphnoch, who Saeko Kageyama secretly places in a stasis tank and goes into hiding with.

While attempting to acquire the Genm Musou Corporation's technology to counter the threat of Zein, the Arch Orphnoch confronts its CEO Kamen Rider Genm before Gai Amatsu intervenes in an attempt to suggest an alliance to fight Zein instead. However, Genm and the Arch Orphnoch refuse and take their leave, with the latter declaring that he would never work with humans.
