This is a list of characters of the 2009–2010 Japanese tokusatsu series Kamen Rider W.

Narumi Detective Agency[edit]

The Narumi Detective Agency (鳴海探偵事務所 Narumi Tantei Jimusho?) investigates Dopant activity, founded by Sokichi Narumi who is murdered while he and Shotaro found Philip during an investigation into the Dopants, leaving Shotaro as his successor.

Shotaro Hidari[edit]

Detective Shotaro Hidari (左 翔太郎 Hidari Shōtarō?) is the man on the streets, having been taught by Sokichi Narumi how to be a private investigator. After Sokichi's death, Shotaro investigates Dopant crimes, and with Philip he fights Dopants as the body of Kamen Rider Double (仮面ライダーダブル Kamen Raidā Daburu?).

During the events of W Forever, Shotaro receives Sokichi Narumi's Lost Driver, allowing him to become Kamen Rider Joker (仮面ライダージョーカー Kamen Raidā Jōkā?) on three occasions. This belt is retrieved by Philip and given to Shotaro before his disappearance, allowing him to become Kamen Rider Joker, again.

Shotaro Hidari is portrayed by Renn Kiriyama (桐山 漣 Kiriyama Ren?). As a child, Shotaro is portrayed by Issei Kakazu (嘉数 一星 Kakazu Issei?). Kakazu later portrays Akira Aoyama in the television series' final episode.


The mysterious Philip (フィリップ Firippu?) is Shotaro's partner in the detective agency who lost his memory and uses his special abilities to access the Gaia Library to solve Dopant crimes. To help fight Dopants, normally Philip uses his mind and consciousness to become Kamen Rider Double. But with the Fang Memory, Philip switches places with Shotaro as Double in FangJoker (ファングジョーカー Fangu Jōkā?) form. Eventually, Philip learns that he is Raito Sonozaki (園咲 来人 Sonozaki Raito?) and had been used by his father Ryubee to create the artificial Gaia Memories for the Museum.

During the events of the novel Kamen Rider W: The One Who Continues After Z, Philip uses the Lost Driver and the Cyclone Memory to transform into the wind-powered Kamen Rider Cyclone (仮面ライダーサイクロン Kamen Raidā Saikuron?).[1]

Philip is portrayed by Masaki Suda (菅田 将暉 Suda Masaki?). As a child, Philip is portrayed by Tomoya Hashimoto (橋本 智哉 Hashimoto Tomoya?).

Akiko Narumi[edit]

Akiko Narumi (鳴海 亜樹子 Narumi Akiko?) is Shotaro's boss and landlord at the Narumi Detective Agency. Because of her young appearance and attitude, Shotaro refers to her as "Middleschool Girl" (女子中学生 Joshi Chūgakusei?) and sees her as a threat to his public image. She has come to Futo from Osaka to find her father and reclaim the agency's building, initially unaware that her father had died and was a Kamen Rider until the events of the Begins Night film. She serves as a personal assistant as well as the boss of the place while on the job as well as keeping Shotaro on the right track by slapping him with a green sandal; she has also used this tactic on other characters, including Dopants. She has a black and white view of the world and tends to say "I won't hear of it!" (私聞いてない! Atashi kiitenai!?) when she is caught off guard by something. Despite her somewhat childish personality, she has shown signs of promise as a detective, particularly in her ability to decipher clues that leave Shotaro, Philip, and Ryu stumped, as well as being extremely protective of clients, a trait she shares with her father. Akiko harbors a crush on Ryu Terui, but her advances are ignored as he maintains a professional demeanor towards her, until he finally gives in to his feelings for her. However, she is ultimately torn due to unresolved issues with her father until the events of Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core when she learns the full story of her father before her wedding to Ryu. During the events of Kamen Rider Accel, due to his inability to call her by name, Akiko believes that Ryu doesn't love her, further worsen after seeing Ryu on the run with Aoi Katsuragi, believing that he cheated on her. But when held captive by the Commander Dopant and saved by her husband, Akiko learns that Ryu truly loves her, though he insists to not call her by her name. In Drive Saga: Kamen Rider Chaser, it is revealed that Akiko and Ryu now have a daughter named Haruna Terui (照井 榛名 Terui Haruna).

Akiko Narumi is portrayed by Hikaru Yamamoto (山本 ひかる Yamamoto Hikaru?). As a child, Akiko is portrayed by Saho Ueda (上田 紗帆 Ueda Saho?) in Kamen Rider Skull: Message for Double.

Sokichi Narumi[edit]

Main article: Kamen Rider Skull

Sokichi Narumi (鳴海 荘吉 Narumi Sōkichi?) is Shotaro's mentor and founder of the Narumi Detective Agency, referred by Shotaro as "Boss" (おやっさん Oyassan?). His policy with investigations is to ensure the client's safety above all else, and unlike Shotaro, he is truly hardboiled in the sense that he will make difficult decisions when he needs to, and follows through with it. However, during the events depicted in Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core, Sokichi became involved in the Dopant cases and gaining the means to become Kamen Rider Skull (仮面ライダースカル Kamen Raidā Sukaru?) from Shroud, who is an old friend of his. Sokichi later accepts a job from Shroud to get Philip away from the Sonozaki Family, transforming into Skull to fend off the Taboo Dopant and an army of Masquerade Dopants during the raid on their factory. But in the end, after talking Philip into coming with him to decide his own fate and find his own atonement, Sokichi is shot in the back and dies telling Shotaro to continue in his place and giving him his white fedora, his dying words being for Shotaro to "grow into a man worthy of wearing it".

Sokichi Narumi is portrayed by singer-songwriter Koji Kikkawa (吉川 晃司 Kikkawa Kōji?).[2] Kikkawa also performs the song "Nobody's Perfect" under the name of his character.

Seiichiro Matsui[edit]

Seiichiro Matsui (松井 誠一郎 Matsui Seiichirō?), or simply known as Matsu (マツ?), was Sokichi Narumi's former partner from the year 1999. He often helped in Sokichi's cases by researching in libraries, as he is described to be a "1999 version of Philip" by Akiko. But he had a bit of envy towards Sokichi for always getting the girl. Meeting with Melissa where she hires him to save her from Yaguchi, a chain of events occur that result in Matsu becoming one of the first Gaia Memory users initially to protect Melissa. However, the Spider Memory warps Matsu's mind to the point of him wanting Melissa for himself, as he always had feelings for her. As the Spider Dopant (スパイダー・ドーパント Supaidā Dōpanto?), he can use threads known as the Spider web (スパイダーウェブ Supaidā Webu?) for attacks and other uses, as well as implanting little Spider Bombs (スパイダーボム Supaidā Bomu?) into humans that would spin silk around a person's loved ones and explode upon touch. Matsu dies after his Gaia Memory is destroyed in a fight with Sokichi as Kamen Rider Skull, who still calls him his "partner". He appears in the film Kamen Rider × Kamen Rider OOO & Double featuring Skull: Movie War Core, when the Pteranodon Yummy uses the Memory Memory to reveal the events of Sokichi Narumi's past.

His organization style in his research is the same style used in the continuation of an episode arc where it shows important individuals involved in the case (including themselves), how they relate to each other, and other possible clues to the case.

The Spider Dopant is an homage to the inhumanoid Spider Man (蜘蛛男 Kumo Otoko?) from the original Kamen Rider television series.[3]

Seiichiro Matsui (Matsu) is portrayed by Taro Yamamoto (山本 太郎 Yamamoto Tarō?).[4]

Futo Police Department[edit]

The Futo Police Department (風都署 Fūtosho?, FPD) force attempts to fight the Dopant crime wave.

Mikio Jinno[edit]

Mikio Jinno (刃野 幹夫 Jinno Mikio?) is a senior detective of the Futo Police working on the Dopant case who is very gullible, falling for the same trick every time until the Jewel Dopant case when he is arrested and vows to himself to be less gullible after being cleared of all charges. Despite his personality, he is a dedicated officer and sometimes wise. He also happens to be a friend of Shotaro's with whom he discusses cases, while unaware of his Shotaro's connection to Kamen Rider Double. It is implied that he has known Shotaro when he was younger as Shotaro recalls being chased by him when Jinno was an officer. He is almost never seen without his back scratcher. In Kamen Rider Accel, after taking down the Kamen Soldiers by himself, Jinno is shot with Ryu's firearm by the Commander Dopant. However, the wound is not fatal and he makes a complete recovery.

Mikio Jinno is portrayed by Takeshi Nadagi (なだぎ 武 Nadagi Takeshi?).

Shun Makura[edit]

Shun Makura (真倉 俊 Makura Shun?) is Jinno's rookie partner, an unpleasant guy who is doubtful of Shotaro's skills and sees his involvement with police investigations unnecessary. He and Shotaro often get into fights when they are together, at times requiring Jinno to break them up. He is extremely impulsive, often jumping to conclusions when it comes to solving crimes and accusing people of committing crimes with little or no proof except from the word of a superior officer. He is nicknamed "Macky" (マッキ Makki?) by Shotaro and the others.

Shun Makura is portrayed by Shingo Nakagawa (中川 真吾 Nakagawa Shingo?).

Ryu Terui[edit]

Main article: Kamen Rider Accel

Ryu Terui (照井 竜 Terui Ryū?) is a young man who is a Superintendent appointed to the Futo Police Department's Paranormal Crime Investigation Division (超常犯罪捜査課 Chōjō Hanzai Sōsaka?), much to the chagrin of Shotaro, Jinno, and Makura. Though he becomes an ally to Shotaro in fighting Dopant crimes as Kamen Rider Accel (仮面ライダーアクセル Kamen Raidā Akuseru?), Ryu originally becomes a Kamen Rider to find his family's murderer, Dr. Shinkuro Isaka. However, it is only after Isaka's death that Ryu learns that there is more to the story behind the death of his family.

Ryu Terui is portrayed by Minehiro Kinomoto (木ノ本 嶺浩 Kinomoto Minehiro?).

Futo Irregulars[edit]

The Futo Irregulars (風都イレギュラーズ Fūto Iregyurāzu?) are denizens of Futo that Shotaro goes to for information and assistance. They are named after the Baker Street Irregulars of the Sherlock Holmes stories. Most of the Futo Irregulars' true names are a mystery.


Watcherman (ウォッチャマン Wotchaman?) is the username of an otaku blogger who is Shotaro's informant on Dopant activities. He also owns a bicycle called Futo-kun Bicycle (ふうとくんバイシクル Fūtokun Baishikuru?) that he won in a mail-in contest.[5] During the events of W Forever, Watcherman obtains the T2 Violence Memory and it forces him to become the T2 Violence Dopant (T2バイオレンス・ドーパント Tī Tsū Baiorensu Dōpanto?), whose left arm and Violence Ball form are pure destruction. After being restored by Double LunaJoker's Joker Strange Maximum Drive, Watcherman is taken to a free clinic where he stays during NEVER's attack.

Watcherman is portrayed by Nasubi (なすび?).


Santa-chan (サンタちゃん?) is a mysterious man who is seen throughout Futo, the owner of a pet shop who promotes local companies by giving out freebies in a Santa Claus outfit. He gives out presents which always seem to help out the recipient. During the events of W Forever, Santa-chan obtains the T2 IceAge Memory and it forces him to become the T2 IceAge Dopant (T2アイスエイジ・ドーパント Tī Tsū Aisueiji Dōpanto?), with the ability to make absolute zero ice. After being restored by Double LunaJoker's Joker Strange Maximum Drive, Santa-chan is taken to a free clinic where he stays during NEVER's attack. One year after the final battle with the Utopia Dopant, Santa-chan is seen as the owner of a pet shop that Shotaro visits, breaking up a fight between Shotaro and an unnamed employee who is later revealed to be the Energy Dopant. Though he is seen in a Santa Claus outfit almost all the time, he ironically dons a reindeer outfit on Christmas Day instead.

Santa-chan is portrayed by Zennosuke Fukkin (腹筋 善之介 Fukkin Zennosuke?).

Queen & Elizabeth[edit]

For the fictional band, see Queen & Elizabeth.

Queen (クイーン Kuīn?) and Elizabeth (エリザベス Erizabesu?) are two teenage girls who serve as Shotaro's informants in high school settings. The two are also singers, who get a major label release for their song "Love♡Wars". In Begins Night, it is revealed that Elizabeth has feelings for Philip. During the events of Kamen Rider W Forever: A to Z/The Gaia Memories of Fate, Queen is seen with the T2 Queen Memory (T2クイーンメモリ Tī Tsū Kuīn Memori?), which can be used to form a barrier around the user. The Gaia Memory attempts to take control of Queen and forms a Living Connector on her arm, but she is able to resist and throw the Memory away. Elizabeth also finds the T2 Accel, Key, and Bird Memories (referencing the real band the two actresses are a part of), giving them to Shotaro without being affected by them.

Queen and Elizabeth are portrayed by Tomomi Itano (板野 友美 Itano Tomomi?) and Tomomi Kasai (河西 智美 Kasai Tomomi?) of AKB48, respectively.[6]

Isamu Bito[edit]

Isamu Bito (尾藤 勇 Bitō Isamu?), also known as Sam (サム Samu?) is a stallholder and an old client of Sokichi Narumi. He has a habit of flicking people painfully in the face with his hand when they say something that annoy him, which he often performed on Shotaro. Ten years ago, Bito took the heat for an armored car robbery involving the Beastman, actually his employee Maruo Arima and Suzuko Arima, a woman he had feelings for. However, after the case is solved, Bito continues with his job.

Bito appears in Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core, where he owns a stall selling pinwheels in the year 1999. Bito introduces Sokichi to Stone to help him solve the "Spider Man" case.

Isamu Bito is portrayed by Kazuyoshi Ozawa (小沢 和義 Ozawa Kazuyoshi?).


Stone (ストーン Sutōn?) is an architecture otaku who is introduced to Sokichi Narumi by Isamu Bito to help them solve the "Spider Man" case with his lock picking talents. Helping Sokichi sneak into the Yaguchi Talent Agency, Stone is captured and murdered by the Bat Dopant. He appears in the film Kamen Rider × Kamen Rider OOO & Double featuring Skull: Movie War Core when the Pteranodon Yummy uses the Memory Memory to reveal the events of Sokichi Narumi's past.

Stone is portrayed by Shiro Tsubuyaki (つぶやき シロー Tsubuyaki Shirō?).[7][8]

Sonozaki Family[edit]

The Sonozaki Family (園咲家 Sonozaki Ke?) is an aristocratic family in Futo who founded the organization known as the Museum (ミュージアム Myūjiamu?). When his son Raito died and was reborn as an avatar of the true Gaia Memory, Ryubee used his organization to produce and distribute the Gaia Memories in the criminal underworld, resulting in the Dopant (ドーパント Dōpanto?) crimewaves. This enabled the Museum to follow through with the Gaia Impact (ガイアインパクト Gaia Inpakuto?). With the exception of Raito and Fumine, each member of the Sonozaki Family owns a special Gaia Memory, called Gold Memories (ゴールドメモリ Gōrudo Memori?), allowing them to assume Dopant forms with the use of a prototype Gaia Driver (ガイアドライバー Gaia Doraibā?) belt which prevents the Gaia Memories from corrupting their minds, though it comes with the cost of unable to use these Memories at full power, but that does not seem to inconvenience them in any way. In the end, when Ryubee's plan almost succeeds, it results with the family estate burning to the ground, marking the end of both its patriarch and the Museum. At the end of the series, when Wakana sacrifices her body to give Philip (Raito) his body back, the family becomes a part of the Earth to watch over Philip and tasks him with the family duty to protect Futo and to change the world for the benefit of mankind.

Ryubee Sonozaki[edit]

Ryubee Sonozaki (園咲 琉兵衛 Sonozaki Ryūbee?) is the seemingly wise yet maniacal head of the Sonozaki Family and leader of the Museum, who is almost always seen smiling or laughing. He sports a commanding presence and can adequately terrify many even without the use of his Terror Memory, which is the main reason why the police leaves him alone even though they have suspicions regarding his activities. He acts as a godfather in the organization and sees the entirety of the city of Futo as his personal kingdom, not letting anyone get in the way of his vision for the city, not even his wife and children. With the Terror Memory, Ryubee can transform into the Terror Dopant (テラー・ドーパント Terā Dōpanto?), who can increase the fear in his victims to maddening levels. He could also summon the Terror Field (テラーフィールド Terā Fīrudo?) to burn his victims or teleport himself and others across long distances and project his power into the Terror Crown (テラークラウン Terā Kuraun?) to create a Barong-like familiar known as the Terror Dragon (テラードラゴン Terā Doragon?). As the head of the Museum, Ryubee oversees the distribution of Gaia Memories, using those who can use them as research specimens, regardless of the harm and deaths that ensued. He does not seem to consider the Kamen Riders fighting the Dopant crimewave a threat, using the data off of them as a means to perfect his plans for Wakana before turning his attention to regain Philip and complete his plan to initiate the Gaia Impact.

It is revealed that Ryubee was an archaeologist who bought the grounds his estate was built on after finding deposits of fossils and relics beneath it, forming the collection at the Futo Museum where he works as its curator. He eventually discovered the location of the planet's consciousness, dubbed the Gaia Memory (地球の記憶 Chikyū no Kioku?), and brought his family to see it. However, when his son Raito fell into the "fountain" of the Gaia Memory and died, but was somehow resurrected by the planet's powers, Ryubee began his plan for the Gaia Impact: an event that would ensure the future of the human race by making them one with the planet itself, much like his son had become. To reach his goal, he used an item dubbed the "Evil Tail" (イーヴィルテイル Īviru Teiru?), an archaeologist's brush with the names of his family inscribed on it, to overcome the fear that would go along with sacrificing them to reach his goal, eventually making him go mad. When he sacrifices Raito (Philip) once more into the Gaia Memory to make his daughter Wakana one with the Earth, he is confronted by both Kamen Riders. While Kamen Rider Accel as the AccelTurbuler destroys his Terror Dragon, Shotaro is able to retrieve Philip's mind and then his body from the aspects of the Gaia Memory in ClayDoll Xtreme to transform into Kamen Rider Double CycloneJokerXtreme to defeat the Terror Dopant and destroy the Terror Memory, along with most of the Sonozaki estate. With Ryubee's mind still broken from years of planning, he enters the still burning ruins of his home, glad that he finally initiated the Gaia Impact. He dies in the blaze, thinking of the good times he had with his family before he discovered the Gaia Memory and claiming that he has no regrets about his life as he dances madly by himself.

During the events of OOO, Den-O, All Riders: Let's Go Kamen Riders, Terror Dopant appears to be a member and leader of Shocker in normal timeline.

Ryubee Sonozaki is portrayed by Minori Terada (寺田 農 Terada Minori?). In the music video for "Nobody's Perfect", the Terror Dopant make a cameo as he fights Kamen Rider Skull.[9][10]

Saeko Sonozaki[edit]

Saeko Sonozaki (園咲 冴子 Sonozaki Saeko?) the eldest of the Sonozaki children who runs an IT company called the Digal Corporation (ディガル・コーポレーション Digaru Kōporēshon?), which serves as a front for Gaia Memory production and distribution. As the Taboo Dopant (タブー・ドーパント Tabū Dōpanto?), she gains the ability to fly and generate deadly plasma balls. Ryubee strictly raised Saeko to believe that their family is superior to all others and that they are destined to rule the world. This loveless upbringing caused her to grow up secretly hating her father, often taking the resulting rage out on her younger sister Wakana, serving as fuel for her own ulterior motives of taking over the Museum to prove herself to her father to be its ideal successor. She also has a tendency to kill her boyfriends if they do not live up to her expectations. When Saeko spares Kirihiko due to his capabilities, she marries him and lets him live until he threatens the Museum's livelihood. He has no problems executing Kirihiko as she had never loved him. After Kirihiko's death, Saeko begins to visit Shinkuro Isaka to improve her Dopant form and focus on her plans for the Museum. After he is almost defeated by the Kamen Riders, she begins to show that she cares for Isaka's well-being, which is likely to be genuine attraction to the doctor. Once her coup against her father fails and Isaka is killed off, Saeko goes on the lam and is hunted down by the Smilodon Dopant, who takes the Taboo Memory and leaves her for dead. However, Saeko is saved by Kazu who offers his support in her scheme to take control of the Museum. After infiltrating the Digal Corporation, now with Wakana as its head, to obtain the Nasca Memory and then using an L.C.O.G on herself instead of using the Memory with a Driver. Without inhibitions posed by a Driver, Saeko is able to use the Gaia Memory in its Level 3 state to become the R Nasca Dopant (Rナスカ・ドーパント R Nasuka Dōpanto?, "R" for both "Red" and "Revenge") to overpower her sister. However, when Wakana evolves to ClayDoll Xtreme, which Saeko proves to be utterly powerless against, she is forced to go after other options to make herself more powerful, such as the Jewel Memory, before the Nasca Memory is destroyed in a confrontation with ClayDoll Xtreme. Later, after her father's death, Saeko is disillusioned until she learns of Wakana's survival and regains the Taboo Memory from Kazu after he announces that she has become the head of the Museum. However, no longer having a reason to prove herself with her father dead, Saeko fights Kazu in order to save her sister. As a result, the Taboo Dopant sacrifices herself to hold off the Utopia Dopant to give Wakana time to run away, resulting in Saeko's death as she finally admits the irony of her last moments in her final breath.

Saeko Sonozaki is portrayed by Ami Namai (生井 亜実 Namai Ami?).[11][12]

Wakana Sonozaki[edit]

Wakana Sonozaki (園咲 若菜 Sonozaki Wakana?) is the youngest daughter and middle child of the Sonozaki family who since her brother's death has been secretly raised to become the key element in her father's plans. Working as a DJ at the local Wind Wave (ウインドウェーブ Uindo Wēbu?) radio station, she hosted the Wakana's Healing Princess (園咲若菜のヒーリングプリンセス Sonozaki Wakana no Hīringu Purinsesu?) show and gained a loyal fanbase as a result. While she puts up a shy and kind persona on the show or whenever a crowd is around, her true personality is the complete opposite. As a member of the Museum, Wakana is able to transform into the ClayDoll Dopant (クレイドール・ドーパント Kureidōru Dōpanto?), enabling her to produce gravitational energy shots, as well as the ability to reform her Dopant body after it is shattered into thousands of pieces. Out of all of the members of the Sonozaki Family, she is the least involved with the Gaia Memory business, as she was doted upon while growing up. After encountering Philip, Wakana begins to have second thoughts about being a Dopant and discards the ClayDoll Memory. It is returned to her by her father, who is aware that she did not lose it as she claims; he later decides to bring her into the family business after Kirihiko's death and is the one chosen to view the effects of the Xtreme Memory on the true Gaia Memory. Before this, Wakana also becomes one of Shinkuro Isaka's unwilling experiments after he modifies her Gaia Driver, subjecting her to more of her Gaia Memory's influence and its short term side effects showing her compatibility with its powers.

After trying to run away with Philip, her father takes her to the Museum's true base of operations. Made to believe by unknown means that she is serving a greater good for the planet's sake, Wakana runs the Museum and the Digal Corporation, bent on bringing Philip back to the Museum to complete the Gaia Impact. Her personality now resembles Saeko, but more ruthless and unforgiving. She is also given the Prototype Organic Information Controlling Organ Body Gaia Progressor (有機情報制御器官試作体・ガイアプログレッサー Yūki Jōhō Seigyo Kikan Shisaku Tai Gaia Puroguressā?), a device based on the Xtreme Memory that is designed to evolve her into the godlike ClayDoll Xtreme (クレイドールエクストリーム Kureidōru Ekusutorīmu?) to prepare her for the Gaia Impact so she become one with the planet's vast knowledge. While armed with tendrils and exponentially more power, Wakana becomes a being like Philip with access to the true Gaia Memory, much like CycloneJokerXtreme. When the Gaia Impact seems to succeed after Philip is thrown into the source of the true Gaia Memory, becoming a living Gaia Memory and fully integrated with the ClayDoll Memory, Wakana loses control when Philip is removed from her body, causing an explosion that destroys the Sonozaki estate. However, in midsts of the blaze, Wakana's unconscious body is carried off by Kazu to the Foundation X research facility to be of use in his own version of the Gaia Impact. However, Shotaro manages to save her before taking her to the hospital. A few days later, Wakana attempts to force her way out of the hospital to resume her family's goal before finally learning that Philip disappeared into the Gaia Memory to save her. After getting the means to invoke the Gaia Impact from Shroud in her final moments, Wakana sacrifices her own existence to bring her brother back via the Xtreme Memory.

Wakana Sonozaki is portrayed by Rin Asuka (飛鳥 凛 Asuka Rin?). As a young child, Wakana is portrayed by Natsuki Kasa (笠 菜月 Kasa Natsuki?).[13][14]

Kirihiko Sudo[edit]

Kirihiko Sudo (須藤 霧彦 Sudō Kirihiko?) is a young man who initially works for the Museum as one of its best Gaia Memory dealers. He also has a professed love of the city of Futo, and in his youth created the city's mascot Futo-kun (ふうとくん Fūtokun?). In his work with the Museum, Kirihiko eventually catches the eye of Saeko and they marry, taking on the Sonozaki surname in place of his own. In being welcomed into the family, he is granted a Gaia Driver along with the ability to become the Nasca Dopant (ナスカ・ドーパント Nasuka Dōpanto?), an expert swordsman armed with the Nasca Blade (ナスカブレード Nasuka Burēdo?) with the powers of flight from the Nasca Wings (ナスカウイング Nasuka Uingu?). As an in-law, Kirihiko is not as fully aware of the truth behind the family business or Kamen Rider Double's existence until confronting him in battle. He eventually discovers that Shotaro is Double, and begins to confront him as a rival to test his Gaia Memory's powers. When he finally discovers the truth behind the Gaia Memories, while suffering near-lethal side effects from eventually reaching Level Two of the Nasca Memory's powers, he tries to take Saeko away from the Museum, but she kills him as he is now a threat to her future plans. Saeko kept his Nasca Memory, eventually using it to transform into the R Nasca Dopant before it was destroyed by ClayDoll Xtreme. In episode 33, it was revealed that he had a sister, Yukie Sudo.

Kirihiko Sudo is portrayed by Yuki Kimisawa (君沢 ユウキ Kimisawa Yūki?).[15]


Mick (ミック Mikku?) is Ryubee's beloved pet blue British Shorthair, named by his son Raito (Philip). Despite being a cat, the Smilodon Memory can transform Mick into the humanoid Smilodon Dopant (スミロドン・ドーパント Sumirodon Dōpanto?) that can discharge electricity and move at blinding speeds, fast enough to evade the homing shots of Kamen Rider Double LunaTrigger and outmaneuver Kamen Rider Accel Trial. He appears to be more intelligent than the average house cat, in that he appears to know that he is able to transform into the Smilodon Dopant and he knows how to transform back into a house cat at will. He is often utilized by the Sonozaki Family to deal with matters outside their estate, such as hunting down Philip and traitors, as well as bodyguard and spy. Mick also appears to favor Wakana over the other members of the family though will faithfully follow Ryubee's orders. While targeting Kyoko, the Smilodon Dopant defeats Accel Trial before Double CycloneMetal catches the cat off guard before destroying his Gaia Driver and Smilodon Memory with the Metal Stag Break Maximum Drive. After Ryubee's death, Mick is brought to live at the Narumi Detective Agency.

Mick is played by a cat named Buri-chan (ブリちゃん?). The Smilodon Dopant's vocalizations are performed by Yasuhiro Takato (高戸 靖広 Takato Yasuhiro?).[16]

Foundation X[edit]

Foundation X (財団X Zaidan Ekkusu?) is a mysterious research foundation that investigates provides funding to the Museum for their work in Gaia Memories. After Saeko is saved by one of its members, she unwillingly becomes an ally to their cause in return to take over the Museum from her father and sister. When Ryubee dies and the Museum is dissolved, Foundation X takes over the Gaia Impact project. But in the end, after Kazu dies, Foundation X cancels all investment in Gaia Memory research to focus on other prospective projects which include the O Medals and Mituaki Gamou's Cosmic Energy research.

Jun Kazu[edit]

Jun Kazu (加頭 順 Kazu Jun?) is the white lab coat-wearing researcher for Foundation X, a valuable member of the organization who allows himself to be modified by the research of those he represents. He appears cold and emotionless, speaking in a flat monotone and when he sees others display emotions, he will drop whatever object he is holding in his hand. However, when roused to sufficient anger he releases his emotions like a torrent. Becoming a sponsor to the Museum and overseeing their investments, Kazu obtains a Gaia Driver and a Gold Memory. This Gold Memory, known as the Utopia Memory, allows him to become the seemingly omnipotent Utopia Dopant (ユートピア・ドーパント Yūtopia Dōpanto?), with reality-bending powers that result from the Utopia Memory's ability to grant its user's wishes, mainly used to repel attacks aimed at him, and absorb the emotions of living beings to further power itself. During the events of Kamen Rider Eternal, Kazu is revealed to have been Doctor Prospect's liaison to the Foundation and gain the psychic abilities of a Quark that enhances his Dopant abilities. At that time, he could use the Eternal Memory to become Kamen Rider Eternal. However, his incompatibility with the imperfect T1 GaiaMemory only enabled him to assume the weaker Red Flare (レッドフレア Reddo Furea?) mode. When Katsumi Daido manages to synch up with the Gaia Memory and negates the Utopia Memory, Kazu is killed by a perfected Kamen Rider Eternal with his body taken by the Foundation to be revived as a Necro-Over.

Arriving in Futo after his conversion, Kazu saves Saeko from her near death at the hands of the Smilodon Dopant out of love while offering the Foundation's support in her attempt to overthrow her father and Wakana. The briefcase he carries with him at all times contains the 26 T2 Gaia Memories; he eventually relinquishes this briefcase to Tabata to send it back to Foundation X's research facilities. After Ryubee's death, Kazu manages to save Wakana from the burning wreckage of the Sonozaki estate with the intent to use her in the Foundation's own version of the Gaia Impact: digitizing her into one of the Foundation's satellites in order to kill all life on Earth that is not compatible with Gaia Memories in an act of cleansing the human race's impurities. However, Wakana's comatose state forces Kazu to wait until her power resurfaces. In order to awaken her and reclaim Saeko, Kazu reveals himself to the Kamen Riders and assumes his Dopant form to overpower them. After discovering that Philip's emotions are tied to Wakana's powers as ClayDoll Xtreme, he decides to attack everyone close to him in order to initiate the Gaia Impact. After he is exposed as a Necro-Over, Kazu professes his love for Saeko and reluctantly kills her when she rebuffs and attacks him. Shotaro breaks into his lair and uses the Memory Gadgets to disable him and save Wakana, catching Kazu as the Utopia Dopant in a massive explosion as the lab goes up around him. He survives, however, and comes after them, battling Kamen Rider Double CycloneJokerXtreme. The duo manage to further weaken him by overloading him with Philip's final feelings before using the Double Prism Xtreme Maximum Drive to defeat the Utopia Dopant. Stumbling to his feet, Kazu asks if his own crime was to love and clicks the Utopia Memory one more time before it shatters and he dissolves away into nothingness.

During the events of OOO, Den-O, All Riders: Let's Go Kamen Riders, Utopia Dopant appears to be a member of Shocker in the altered timeline.

She is often seen with a stopwatch, as she is very strict when it comes to keeping schedules. She is shown to check her stopwatch frequently and doing strict allocations of time for matters, even interrupting others' talking and not sparing even a second more, should it affect her schedule. After Jun Kazu's defeat, she officially decides to end the foundation's Gaia Memory research.

Neon Ulsland is portrayed by Maria Theresa Gow (マリア・テレサ・ガウ Maria Teresa Gau?). She previously played Georgie Leland, one of the XIG American members, in Ultraman Gaia.[18]

Doctor Prospect[edit]

Doctor Prospect (ドクター・プロスペクト Dokutā Purosupekuto?) was a Foundation X scientist who during the events of Kamen Rider Eternal was studying the use of psychic ability and created an army of psychic-powered soldiers known as Quarks (クオークス Kuōkusu?). To enforce his will upon the Quarks, Prospect can assume the form of the Eyes Dopant (アイズ・ドーパント Aizu Dōpanto?), able to detect an opponent's next move to counterattack, to brand the Quarks with an eye marking on their foreheads that would kill them should they try to escape. He also uses barrier known as Heaven's Horn (ヘブンズホーン Hebunzu Hōn?) to weed out weaker Quarks and ensure they die a peaceful death. In his fight with Katsumi Daido as Kamen Rider Eternal, he manages to kill all of the Quarks, including Mina as it seemed at the time, which enrages Daido and makes him go mad, killing Doctor Prospect by destroying his Gaia Memory and leaving him victim to its psychic killing effect.

Doctor Prospect is portrayed by Jyunichi Haruta (春田 純一 Haruta Jun'ichi?).


Lloyd (ロイド Roido?) was one of Doctor Prospect's Quarks bodyguards before he was killed off by Gozo.

Lloyd is portrayed by Sho Tomita (富田 翔 Tomita Shō?).

She is a suit actress in Japan Action Enterprise who has worked on various Super Sentai and Kamen Rider Series productions, including being in the Geki Yellow suit for Juken Sentai Gekiranger and the Shinken Pink suit for Samurai Sentai Shinkenger; Hitomi also had a small out-of-costume part in Gekiranger episode 36 as the thief Lily.


The Special Mercenary Force "NEVER" (特殊傭兵部隊NEVER Tokushu Yōhei Butai Nebā?) are composed of humans who have been revived from death and turned into super soldiers called Necro-Overs (ネクロオーバー Nekuroōbā?), the product of research, which was initially a project initiated by Maria Daido attempting to resurrected her son who died from a traffic accident, by Foundation X to duplicate the conditions that revived Raito Sonozaki (Philip) after his demise in the source of the true Gaia Memory. However, they are required to regular injections of a bio-stabilizer to keep their bodies intact. Leaving Foundation X after being rejected in favor of Gaia Memory research for the latter far greater diversity in abilities, NEVER became mercenaries, leaving a path of destruction in their wake to convince the Foundation that they are better than the Museum's "toys". However, an encounter with Doctor Prospect drove their leader insane and they decided to destroy the Museum by obtaining the T2 Gaia Memories in order to power the X Bicker (エクスビッカー Ekusu Bikkā?) and convert the residents of Futo into Necro-Overs. Though much stronger, faster and more durable than normal humans, their ability to feel emotions diminishes with time, gradually rendering them increasingly undead-like. Like normal humans, they also display exceptional compatibility with certain Gaia Memories. However, Necro-Overs use Gaia Memories at even greater risk than normal humans, for being struck with a Maximum Drive will, instead of reverting to human form as with the case of humans, cause them to disintegrate instead. A Scanning Charge, Kamen Rider OOO's finisher, can also cause a Necro-Over struck by it to disintegrate, and they can become destabilized if injected with a bio-stabilizer blocker fluid. This is reversible only if the Necro-Over can be treated with an antidote quickly. NEVER primarily appears in Kamen Rider W Forever: A to Z/The Gaia Memories of Fate, but their origins are revealed in Kamen Rider Eternal.

Katsumi Daido[edit]

Katsumi Daido (大道 克己 Daidō Katsumi?) is the leader of NEVER who fights with only a combat knife as his side arm. As revealed in The Beginning of N/Blood and Dream, Daido was born in Futo with a congenital heart defect. As a result, combined with a near-fatal car crash, his mother Maria uses her Necro-Over project research to revive her son as the first Necro-Over. Using bio-stimulants to enable him to properly age, Daido proves a superior fighter yet he and his mother turn against Foundation X after the Necro-Over project is rejected. Soon after, he recruits four people who recently died and were revived as Necro-Overs, forming a band of hired mercenaries. During one of their missions, Daido meets Mina and falls in love with her. During that time, Daido gains the experimental Eternal Memory and is able to transform into Kamen Rider Eternal (仮面ライダーエターナル Kamen Raidā Etānaru?). However, being forced to watch Mina seemingly die before his eyes turns Daido into a completely unfeeling monster as he kills Doctor Prospect, with the Eternal Memory getting damaged in the fight. Deciding to destroy Futo to wipe out the Museum, Daido serves as the main antagonist for W Forever and uses the T2 Eternal Memory to regain his Kamen Rider form. After his plans are thwarted by the combined efforts of Shotaro, Philip, and Maria, Daido utilizes all 26 T2 Gaia Memories to overpower Double, but is defeated and slain by CycloneJokerGoldXtreme. Long after their battle with the Museum ends, Shotaro and Philip learned the truth behind Daido's actions and pay their respects.

As Kamen Rider Eternal, Katsumi Daido uses the T2 Eternal Memory (T2エターナルメモリ Tī Tsū Etānaru Memori?) and a Lost Driver to assume the form of Blue Flare (ブルーフレア Burū Furea?) with the Eternal Robe (エターナルローブ Etānaru Rōbu?) cape. His Maximum Drive is called the Eternal Requiem (エターナルレクイエム Etānaru Rekuiemu?) which generates a power wave that neutralizes an enemy Gaia Memory in sight, while the T2 version neutralizes all Gaia Memories with the exception of T2 Memories, a variation of this finisher also executes a Rider Kick to the target. Eternal is armed with the combat knife called the Eternal Edge (エターナルエッジ Etānaru Ejji?), which he uses in another Maximum Drive called the Bloody Hell Blade (ブラッディヘルブレイド Buraddi Heru Bureido?). Eternal can use other T2 Gaia Memories to access their powers like the T2 Unicorn Memory (T2ユニコーンメモリ Tī Tsū Yunikōn Memori?) to create an energy drill around his fist and the T2 Zone Memory (T2ゾーンメモリ Tī Tsū Zōn Memori?) to summon the other T2 Gaia Memories to him. In addition to the Maximum Slots on the Lost Driver and Eternal Edge, Eternal has a series of Gaia Memory Slots on combat belts around its chest, right arm, and left leg; with the Memory Slot in the Lost Driver, a total of 27. By filling all of these Memory Slots with the T2 Gaia Memories, Eternal is powered into his Strengthening Armament (強化武装 Kyōka Busō?) mode, able to absorb the X-Bicker energy to produce the Eternal Wave (エターナルウェーブ Etānaru Wēbu?) green aura that he uses in his Neverending Hell (ネバーエンディングヘル Nebāendingu Heru?) Maximum Drive.[19][20] His catchphrase is "Now, enjoy your Hell" (さあ、地獄を楽しみな Saa, jigoku o tanoshimina?). Eternal's motifs is that of the letter E and a military commando.

The last person he saw alive was Daido, whom he fell in love with and became his right hand man, tending to call him Katsumi-chan and expressing any jealously against anyone who gets close to Daido. Armed with a whip, Kyosui is an expert in grappling and can wrap himself around an opponent's body to snap them like twigs. Using the T2 Luna Memory to transform into the Luna Dopant (ルナ・ドーパント Runa Dōpanto?), he uses the power of illusions to produce the T2 Masquerade Dopants along with extending his whip-like arms to any distance. Though he manages to overpower Double, the Luna Dopant has a tougher time fighting Kamen Rider OOO, who destroys him with the Medajaribur's OOO Bash finishing attack.

Captured by Doctor Prospect's men, she helps Katsumi Daido in saving the Quarks before she is horrified to see the change in his personality after their deaths. However, regardless of the complete change, Reika believed there will was some good left in Daido. Following Daido to Futo, she uses the T2 Heat Memory to transform into the Heat Dopant (ヒート・ドーパント Hīto Dōpanto?) with control over fire. She fights against Kamen Rider Joker but is defeated by his Rider Kick Maximum Drive. She manages to reach Futo Tower before starting to disintegrate, begging Daido for aid.

Masquerade Dopants[edit]

Masquerade Dopants (マスカレイド・ドーパント Masukareido Dōpanto?) are Dopants used by the Sonozaki family as guards and other forms of agents, and later used by the Foundation X. Mass-produced Masquerade Memories are distributed to their Gaia Memory salesmen for the purpose of producing more thugs to do their dirty work. The Masquerade Dopants differ from other Dopants as they retain human form, wearing a masks that have a spine and rib cage design, resembling the bony design of the Dopant Gaia Memories. Masquerade Dopants are also significantly weaker than other Dopants, devoid of any special abilities and can be sufficiently fought against by normal humans. Unlike more advanced Dopants as well, they are completely destroyed when taken down with sufficient force, which can be done without using a Maximum Drive.

Father Roberto Shijima[edit]

Father Roberto Shijima (神父・ロベルト志島 Shinpu Roberuto Shijima?) is a figure within the cult known as the Order of Silence and Darkness (闇と静寂の会 Yami to Seijaku no Kai?). Shijima can become the Dummy Dopant (ダミー・ドーパント Damī Dōpanto?) who can assume any form he wishes. Among these forms is the Death Dopant (デス・ドーパント Desu Dōpanto?), using his powers to mimic the real Death Dopant's ability to bring people back from the grave. Using the Death Dopant's form, Father Shijima targets upper-class people by assuming the forms of their recently deceased relatives to frighten them and push them to an early grave. He uses this power on Asami Mutsuki by assuming the identity of her sister Erika, while assuming Sokichi Narumi's form to discourage Shotaro's interference. Once exposed, the Dummy Dopant evades Double as he finds himself in the middle of Decade's fight with Super Shocker, where he takes control of the Mammoth Mecha (マンモスメカ Manmosu Meka?).

"Shroud" (シュラウド Shuraudo?) is a mysterious woman who is seeking revenge against Ryubee Sonozaki and the Museum and is Sokichi Narumi's childhood friend. Ryubee refers to her as the embodiment of rage. Her face is wrapped in bandages to obscure her identity as well as her disfigured face, and she is always seen wearing sunglasses, a large black fedora, and a black trenchcoat. Shroud first appears to provide Ryu Terui with the equipment he needs to become and fight as Kamen Rider Accel, seeing him as a kindred spirit in Ryu's goal to seek revenge against his family's murderer: the owner of the W Memory Shinkuro Isaka. She later sends manuals and Gaia Memories to Philip to build the Frog Pod and Denden Sensor. When Philip is nearly killed by the Weather Dopant, Shroud approaches Philip via the Xtreme Memory, addressing him as Raito, to convince him to end his partnership with Shotaro Hidari as Shotaro is only holding back his powers. She is taken aback when Shotaro and Philip manage to become CycloneJokerXtreme, as with Shotaro's body unfit for advanced Gaia Memory use, such transformation should have no chance of happening. Shroud also gives Ryu the Trial Memory to train him to become Accel Trial, planning to have him die due to his inability to use the Gaia Memory properly and his change of heart in his anger towards Isaka.

After it is revealed to Ryu that Shroud is the one who gave Isaka the Weather Memory, she reveals that she is Fumine Sonozaki (園咲 文音 Sonozaki Fumine?), wife of Ryubee and mother to Saeko, Wakana, and Raito (Philip). While a member of the Museum, she developed the Kamen Riders' Gaia Memories and the T2 Gaia Memories. After Raito died and was revived by the Gaia Memory, she wished to take him away from her husband who only wanted to use the boy as a tool in his plans. After he attacked her as the Terror Dopant, severely scarred by his Terror Field in the process, she left him and spent the next ten years plotting her revenge. She claimed that her first attempt was to use Isaka to kill her husband, but she did not predict that he would test his newfound powers with a murderous streak. She later provided Sokichi Narumi with the needs to build the hangar beneath his agency's offices, as well as the Lost Driver and Skull Memory; only if he would be able to save Raito from the Museum. However, after seeing that her plans on having Terui and Philip transform together into CycloneAccelXtreme would be unnecessary, she decides that she no longer needs to fight for revenge, and allows the Kamen Riders to fight as they wish. She returns to the family estate one last time, after Philip is taken in to allow Wakana to initiate the Gaia Impact, and imparts with him the knowledge that Shotaro Hidari is a wild card, as well as Philip's only family from here on out; this allows him to later save himself from the Gaia Memory, thwarting the Museum's plans. After the final battle with Foundation X, Shroud is seen in a flashback where she speaks with Wakana who seeks to initiate the Gaia Impact on her own. After telling her daughter the information she needs is in the Gaia Library, Shroud quietly passes away at Wakana's side. Shroud is last seen within the Gaia Library with the rest of her family, saying their goodbyes to the revived Philip and stating they will keep watch over him from as parts of the Earth.

Shroud has her own refined Gaia Memory called the Bomb Memory (ボムメモリ Bomu Memori?) which she uses in the Shroud Magnum (シュラウドマグナム Shuraudo Magunamu?) gun, a red-colored version of Double's Trigger Magnum. Its Maximum Drive shoots out a sphere of energy which splits into several smaller spheres that explode. Shroud also has several supernatural powers that do not have a basis in Gaia Memory use. She is able to summon up rings of fire that produce various objects, as well as appear out of thin air, and disappear just as easily. How she is able to do so is never explained in the series, although it is implied in the movie's Director's Cut Commentary that she is a Quark.

Shroud is voiced by Naoko Kouda (幸田 直子 Kōda Naoko?), while Yūki Ono (小野 友紀 Ono Yūki?) serves as the suit actor.

Shinkuro Isaka[edit]

Shinkuro Isaka (井坂 深紅郎 Isaka Shinkurō?) is the head physician at the Isaka Medical Clinic (井坂内科医院 Isaka Naika Iin?). Ten years ago, finding no meaning in his life, he encountered Ryubee Sonozaki attacking a group of people as the Terror Dopant. This brings maddening joy to the doctor and he made a point to get the Terror Memory for himself, experimenting on himself with numerous Gaia Memories with various Living Connectors on his body before Shroud gave him the Weather Memory in the hope that he would be powerful enough to eliminate Ryubee. As the Weather Dopant (ウェザー・ドーパント Wezā Dōpanto?), he is armed with the whip-like Weather Mine (ウェザーマイン Wezā Main?) and control over the weather: intense sunlight, heavy rain, lightning, tornadoes, and freezing snow. He originally tested these abilities in a series of murders which include Ryu Terui's family, to whom he is only known as the man with the W Memory (W(ダブリュー)のメモリを持つ男 Daburyū no Memori o motsu otoko?). Isaka does not use a Gaia Driver, as he feels he doesn't need the protection provided, as he is unaffected by their corruption due to him being already intensely psychotic, and the limits imposed on the power of Gaia Memories annoy him greatly. The Weather Dopant can also withstand Maximum Drives, as he has augmented the Weather Memory with other Gaia Memories' powers. This skill and his knowledge of Dopant physiology makes him an ally to the Museum. After his identity is discovered during his failed attempt to add the Invisible Memory to his arsenal, Isaka takes refuge in the Sonozaki estate where he convinces Saeko to take out her father so she can control the Museum and he can get the Terror Memory. Though he originally sees Saeko as merely one of his pawns and research material, he admits to having developed feelings for her. During his attempt to absorb the Quetzalcoatlus Memory, the Weather Dopant is finally defeated by Kamen Rider Accel Trial's Machine Gun Spike Maximum Drive, shattering the Weather Memory. Shortly afterwards, Isaka's excessive use of Gaia Memories causes his body to become covered in Living Connectors that dissolve him away into nothingness as he tells the Kamen Riders that Shroud will be their end. Shroud later expressed regret to Ryu for giving Isaka the Weather Memory, having no idea of what a monster he would become with the Memory.

Shinkuro Isaka is portrayed by Tomoyuki Dan (檀 臣幸 Dan Tomoyuki?).[26]
