This is a list of characters of the 2009–2010 Japanese tokusatsu series Kamen Rider W and its manga sequel, Futo Detectives.

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.

Kamen Rider Double[edit]

Kamen Rider Double (仮面ライダーW (ダブル), Kamen Raidā Daburu) is a Kamen Rider transformed by both Shotaro Hidari and Philip through the Double Driver (ダブルドライバー, Daburu Doraibā) belts and their own set of purified USB memory-like Gaia Memories (ガイアメモリ, Gaia Memori). The Double Drivers linked, they are used to transfer Philip's consciousness into Shotaro along with the former's inserted Gaia Memory. Their catchphrase at the start of a battle is "Now, count your sins!" (さあ、お前の罪を数えろ!, Saa, omae no tsumi o kazoero!), which is originally used by Sokichi Narumi. Double's ability to function is dependent on the condition of both Shotaro and Philip, as any disruption physical or mental could affect the Kamen Rider's mobility or cancel the transformation entirely. Double rides the modified Honda CBR1000RR motorcycle called the HardBoilder (ハードボイルダー, Hādo Boirudā), using the Rotation-Interchange Base RevolGarry (回転換装ベースリボルギャリー, Kaiten Kansō Bēsu Riborugyarī) mobile garage to covert it into the HardTurbuler (ハードタービュラー, Hādo Tābyurā) hovercraft or the HardSplasher (ハードスプラッシャー, Hādo Supurasshā) personal water craft.

Normally, Double uses different combinations of Gaia Memories to access various combinations of powers, weapons, strengths, and weaknesses through Half Changes (ハーフチェンジ, Hāfu Chenji), switching from one form to another by switching out one or both Gaia Memories in the belt in a Memory Change (メモリチェンジ, Memori Chenji). Each Half Change uses a Maximum Drives (マキシマムドライブ, Makishimamu Doraibu) finisher, which is designed to destroy a Dopany's Gaia Memory via Memory Break (メモリブレイク, Memori Bureiku).

  • CycloneJoker (サイクロンジョーカー, Saikuron Jōkā): Double's default form using the Cyclone and Joker Memories, the most well-balanced of Double's usual form with his wind-powered kicks having increased damage and cutting potential. This form's Maximum Drive finisher is a Rider Kick called the Joker Extreme (ジョーカーエクストリーム, Jōkā Ekustorīmu), during which a tiny controlled tornado lifts Double into the air before the Kamen Rider's body splits down the middle as the halves reach their target in a drop kick fashion before reconnecting.
    • CycloneMetal (サイクロンメタル, Saikuron Metaru): A Half Change accessed through the Cyclone and Metal Memories, using the Metal Shaft to creates blades of wind. This form's Maximum Drive finisher is the Metal Twister (メタルツイスター, Metaru Tsuisutā) where Kamen Rider Double spins around while swinging the Metal Shaft covered in an aura of wind.
    • CycloneTrigger (サイクロントリガー, Saikuron Torigā): A Half Change accessed through the Cyclone and Trigger Memories, using the Trigger Magnum to shoot out highly compressed air. This form's Maximum Drive finisher is the Trigger Aerobuster (トリガーエアロバスター, Torigā Earobasutā), firing multiple shots of pressurized air at the enemy.
  • HeatMetal (ヒートメタル, Hīto Metaru): Double's form using the Heat and Metal Memories, considered the strongest, yet slowest of the 9 forms while imbuing the Metal Shaft with fire to increase its destructive abilities. This form's Maximum Drive finisher is the Metal Branding (メタルブランディング, Metaru Burandingu), causing one or both ends of the Metal Shaft to ignite on fire and deliver a final blow to the opponent. First used in Kamen Rider Decade: All Riders vs. Dai-Shocker.
    • HeatJoker (ヒートジョーカー, Hīto Jōkā): A Half Change form accessed through the Heat and Joker Memories, enabling Double to throw flaming punches. This form's Maximum Drive finisher is a Rider Punch called the Joker Grenade (ジョーカーグレネード, Jōkā Gurenēdo), during which Kamen Rider Double somersaults in mid-air, then HeatJoker's body splits down the middle during descent as the halves each hit the target with elementally energized hooks. First used in Kamen Rider Decade: All Riders vs. Dai-Shocker.
    • HeatTrigger (ヒートトリガー, Hīto Torigā): A Half Change accessed through the Heat and Trigger Memories, using the Trigger Magnum to shoot blasts of fire. This form's Maximum Drive finisher is the Trigger Explosion (トリガーエクスプロージョン, Torigā Ekusupurōjon), which fires a single constant stream of fire that completely vaporizes the enemy. HeatTrigger is the only form of Kamen Rider Double's that has attempted to perform a Twin Maximum, in which the Trigger Magnum blasts out a massive fireball that incinerates anything in its path.
  • LunaTrigger (ルナトリガー, Runa Torigā): A form accessed through the Luna and Trigger Memories, effective in long range using the Trigger Magnum to fire curving gold and blue energy bolts that home on their intended target. This form's Maximum Drive finisher is the Trigger Full Burst (トリガーフルバースト, Torigā Furu Bāsuto), which fires multiple charged homing shots at the enemy.
    • LunaJoker (ルナジョーカー, Runa Jōkā): A Half Change accessed through the Luna and Joker Memories, enabling Double to stretch his right limbs to extend his strike range. This form's Maximum Drive finisher is a Rider Chop called the Joker Strange (ジョーカーストレンジ, Jōkā Sutorenji), during which LunaJoker splits down the middle, the Luna half makes four copies of itself, and all five Luna halves execute rapid-fire karate chops on the target, and then the Joker half strikes the target with an energy powered chop.
    • LunaMetal (ルナメタル, Runa Metaru): A Half Change accessed through the Luna and Metal Memories, enabling the Metal Shaft's range to be extended to the point of the weapon being used like whip. This form's Maximum Drive finisher is the Metal Illusion (メタルイリュージョン, Metaru Iryūjon) where Kamen Rider Double spins the Metal Shaft around to create golden rings that float around Kamen Rider Double, before unleashing them upon the target all at once.

Double also uses Memory Gadgets (メモリガジェット, Memori Gajetto) are items powered by artificial Gaia Memories called Giji Memories (ギジメモリ, Giji Memori, "Pseudo Memories") that change from Gadget Mode (ガジェットモード, Gajetto Mōdo) to Live Mode (ライブモード, Raibu Mōdo) to give Double's weapon's a boost with the use of a Soul Memory activating a Maximum Drive.

  • The Stag Phone (スタッグフォン, Sutaggu Fon) are two cellular phones Shotaro and Philip own which switch between Cell Phone Mode (携帯モード, Keitai Mōdo) and Stag Mode (スタッグモード, Sutaggu Mōdo) with the use of the Stag Memory (スタッグメモリ, Sutaggu Memori). Double uses a Stag Phone to normally summon and control the HardBoilder and the RevolGarry, but attaches it to Trigger Magnum to execute a Trigger Stag Burst (トリガースタッグバースト, Torigā Sutaggu Bāsuto) Maximum Drive or with the Metal Shaft to perform the Metal Stag Break (メタルスタッグブレイク, Metaru Sutaggu Bureiku) Maximum Drive.
  • The Spider Shock (スパイダーショック, Supaidā Shokku) is a G-Shock wrist watch that switches between Wrist Watch Mode (腕時計モード, Udedokei Mōdo) and Spider Mode (スパイダーモード, Supaidā Mōdo) with the use of the Spider Memory (スパイダーメモリ, Supaidā Memori). It has a grappling hook in Wrist Watch Mode. It can also shoot out trackers which can be tracked in Wrist Watch Mode. When attached to the Trigger Magnum, it allows Kamen Rider Double to fire out a net that can capture Dopants. When attached to the Metal Shaft, it allows Kamen Rider Double to shoot out a webbed string that restrains a Dopant
  • The Bat Shot (バットショット, Batto Shotto) is a digital camera that switches between Digicam Mode (デジカメモード, Dejikame Mōdo) and Bat Mode (バットモード, Batto Mōdo) with the use of the Bat Memory (バットメモリ, Batto Memori). A live video feed can be linked to the Stag Phone while in Bat Mode. Its flash can disorient others, and when attached to the Metal Shaft (a combination that Shotaro dubs the Sonic Shaft (ソニックシャフト, Sonikku Shafuto)), it can emit sonic waves strong enough to shatter solid objects. The Bat Shot also has a Maximum Drive for the Luna Memory, allowing its flashes to reveal and stun any hidden targets in its vicinity. When attached to the Trigger Magnum, it allows Kamen Rider Double to perform the Trigger Bat Shooting (トリガーバットシューティング, Torigā Batto Shūtingu) Maximum Drive, locking onto the target through the Bat Shot and then firing a concentrated blast from the Trigger Magnum.
  • The Frog Pod (フロッグポッド, Furoggu Poddo) is a speaker that switches between Speaker Mode (スピーカーモード, Supīkā Mōdo) and Frog Mode (フロッグモード, Furoggu Mōdo) with the use of the Frog Memory (フロッグメモリ, Furoggu Memori), which is similar to a MP3 Player that acts as a sound recorder. When the recording is played back, the Frog Pod can modulate the sound to be anyone's voice. Its primary uses are for audio recording and analysis. The Frog Memory and manual for building the Frog Pod are sent to Philip by what he assumed to be Shroud.
  • The Denden Sensor (デンデンセンサー, Denden Sensā) is a pair of night vision goggles that switches between Goggle Mode (ゴーグルモード, Gōguru Mōdo, also translated as "Night Scope Mode") and Denden Mode (デンデンモード, Denden Mōdo) with the use of the Denden Memory (デンデンメモリ, Denden Memori). Its primary ability is to detect changes in the light spectra and alert its user to targets invisible to the naked eye. It is also used as a surveillance device, being able to store 8 terabytes of information in its Giji Memory. The Denden Sensor is the second Memory Gadget Philip is seen constructing from a set of instructions sent to him by Shroud.

The Xtreme Memory (エクストリームメモリ, Ekustorīmu Memori) is a special bird-like Gaia Memory that changes from Live Mode (ライブモード, Raibu Mōdo) to Memory Mode (メモリモード, Memori Mōdo) for Double to assume his ultimate form: CycloneJokerXtreme (サイクロンジョーカーエクストリーム, Saikuron Jōkā Ekusutorīmu). Being an evolved form of Double's CycloneJoker form, the Xtreme Memory contains a digitized Philip which causes him and Shotaro to fully integrate into a single being for the duration of the form with full access to the True Gaia Memory via the iridescent band going down the middle of the Kamen Rider's body called the Crystal Server (クリスタルサーバー, Kurisutaru Sābā). Double CycloneJokerXtreme uses the Prism Bicker (プリズムビッカー, Purizumu Bikkā) that splits into the Prism Sword (プリズムソード, Purizumu Sōdo), which neutralizes more Dopants' regenerative abilities, and Bicker Shield (ビッカーシールド, Bikkā Shīrudo) which uses the Prism (プリズム, Purizumu) Memory to links the power of four Maximum Drives into one. Double's Maximum Drives in this form are the Double Xtreme (ダブルエクストリーム, Daburu Ekusutorīmu) Rider Kick, Double Prism Xtreme (ダブルプリズムエクストリーム, Daburu Purizumu Ekusutorīmu) kick, Prism Break (プリズムブレイク, Purizumu Bureiku),Bicker Charge Break (ビッカーチャージブレイク, Bikkā Chāji Bureiku) sword and shield charged slash, and the Bicker Finallusion (ビッカーファイナリュージョン, Bikkā Fainaryūjon) laser blast. Double can evolve the form further by assuming CycloneJokerGoldXtreme (サイクロンジョーカーゴールドエクストリーム, Saikuron Jōkā Gōrudo Ekusutorīmu) form being exposed to strong winds, like in Kamen Rider W Forever: A to Z/The Gaia Memories of Fate, with use of the Golden Xtreme (ゴールデンエクストリーム, Gōruden Ekusutorīmu) Rider Kick Maximum Drive.

Shotaro Hidari[edit]

Shotaro Hidari (左 翔太郎, Hidari Shōtarō) is the man on the streets, a self-proclaimed "hardboiled detective" who emulates famous pulp fiction private eyes characters while dressing himself in 1940s fashion with a sharp enough intuition to sometime figure out the culprit behind a crime before having Philip confirm his suspicions with evidence. Vowing to ensure that no one ever feels sad, Shotaro became a protégé of Futo's private investigator Sokichi Narumi after admiring his work as a child. Unlike his mentor, Shotaro was incapable of making the tough decisions most of the time due to his kindhearted nature, which is the main reason why many consider him "halfboiled".

Following Sokichi's death in the Begins Night (ビギンズナイト, Biginzu Naito) incident, their investigation leading to Shotaro meeting Philip, Shotaro promises to continue in his mentor's stead while becoming a man worthy of wearing Sokichi's white fedora. Thus Shotaro works to stop the Dopant crime wave in Futo by providing his body as Kamen Rider Double, taking pride in the role and being called a "Kamen Rider" by the citizens. While his body was not meant to handle Gaia Memories as he was never intended to be partnered with Philip, Shotaro adapted to the situation as he eventually become both worthy of being Double and wearing Sokichi's white fedora.

As Double, Shotaro possesses Gaia Memories called Body Memories (ボディメモリ, Bodi Memori) which form the left side of Double's body while determining the fighting style in conjunction with Philip's Soul Memories. They are also used in Double's Maximum Drive attacks.

  • Joker (ジョーカー, Jōkā): The Joker Memory, also known as the Ace Memory (切り札の記憶, Kirifuda no Kioku), allows the user to increase fighting potential and enhances the users reflexes significantly, becoming the Skill Warrior (技戦士, Waza Senshi). When used, half of Kamen Rider Double becomes the black Ace Left Half (切り札の左半身, Kirifuda no Hidari Hanshin). 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.
  • Metal (メタル, Metaru): The Metal Memory, also known as the Steel Memory (鋼鉄の記憶, Kōtetsu no Kioku) or the Fighter Memory (闘士の記憶, Tōshi no Kioku), empowers the user with great strength and magnified resistance to physical harm, becoming the Superpowered Warrior (怪力戦士, Kairiki Senshi). When used, half of Kamen Rider Double becomes the silver Fighter Left Half (闘士の左半身, Tōshi no Hidari Hanshin). Forms using the Metal Memory are armed with the extendable Metal Shaft (メタルシャフト, Metaru Shafuto) .
  • Trigger (トリガー, Torigā): The Trigger Memory, also known as the Sniper Memory (銃撃手の記憶, Jūgekishu no Kioku), turns the user into an expert marksman, becoming the Gun Warrior (銃戦士, Jū Senshi). When used, half of Kamen Rider Double becomes the blue Sniper Left Half (狙撃手の左半身, Sogekishu no Hidari Hanshin) while arming the form with the Trigger Magnum (トリガーマグナム, Torigā Magunamu). When the Trigger Memory is placed in the Maximum Slot on the Trigger Magnum, the weapon changes from Normal Mode to Maximum Mode to fire an elemental-powered Maximum Drive attack.

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), who also portrays Akira Aoyama (青山 晶, Aoyama Akira) 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. He was originally Raito Sonozaki (園咲 来人, Sonozaki Raito), the third child and only son of the Sonozaki family who died was revived as an avatar of the planet's consciousness Gaia Memory (地球の記憶, Chikyū no Kioku). Thus Raito was considered the "Chosen Child" (運命の子, Unmei no Ko) by his father Ryubee who had Satoshi Yamashiro wipe out the now ageless youth's memories of his former identity to be used by the Museum in the mass production of artificial Gaia Memories. After being rescued by Shotaro and Sokichi Narumi, the latter naming him after the fictional detective Philip Marlowe, Philip aids Shotaro to atone for being used as a puppet willingly by his captors. Normally remaining in the Detective Agency's secret hangar, reading at his spare time with a habit of becoming obsessed with a topic of interest, Philip investigates Dopant activities through his ability to access the Gaia Library (地球(ほし)の本棚, Hoshi no Hondana) and its Infinite Archive (無限アーカイブ, Mugen Ākaibu), a metaphysical realm and Akashic records in the form of white room filled with an endless number of books on an endless number of bookshelves.

While initially a logic-minded sociopath with little common sense who constantly irks all around him, Philip gradually becomes more empathic while eventually learning his former identity as a member of the Sonozaki Family. He was eventually captured and was absorbed by Wakana to restore the Museum's hold on the True Gaia Memory, later extracted by Shotaro. But the event renders Philip's body unstable to the point that should he transform into Kamen Rider Double again, he would break up into data and be completely absorbed by the planet once he cancels transformation. Saving their final transformation to save Wakana and fight Jun Kazu, Philip has Shotaro promise him that he will still fight for Futo even after he is gone. After Kazu is defeated, Philip bids his final farewell to Shotaro as he fades away once the transformation is cancelled. Before he left, Philip left Shotaro a gift containing a Lost Driver buckle and the blank book he used to bring around with him, containing a message thanking Shotaro and asking him to continue to protect Futo. However, after Wakana learns that Philip sacrificed his own physical existence to save her, she initiates her own Gaia Impact: sacrificing herself to bring back the Xtreme Memory and reconstruct Philip's physical body. Before returning, Philip has one last moment with his family who tell him that they will be watching over him. Once revealing himself a year after his physical form is completely restored, Philip resumes protecting Futo with Shotaro.

As Double, Philip possesses Gaia Memories called Soul Memories (ソウルメモリ, Souru Memori) which transfer his consciousness into Shotaro's body, providing both the right half of Double's body and his elemental power.

  • Cyclone (サイクロン, Saikuron): The Cyclone Memory, also known as the Windy Memory (風の記憶, Kaze no Kioku), allows the user to move at fast speeds, controlling the very power of wind, becoming the Windy Warrior (風の戦士, Kaze no Senshi). When used, half of Kamen Rider Double becomes the green Cyclonic Right Half (旋風の右半身, Senpū no Migi Hanshin). Forms using the Cyclone Memory possess a silver scarf known as the Windy Stabilizer (ウィンディスタビライザー, Windi Sutabiraizā) hanging from the neck. 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]
  • Heat (ヒート, Hīto): The Heat Memory, also known as the Hot Memory (熱き記憶, Atsuki Kioku), empowers the user with the element of fire, becoming the Blazing Warrior (炎の戦士, Honō no Senshi). When used, half of Kamen Rider Double becomes the red Heated Right Half (熱き右半身, Atsuki Migi Hanshin).
  • Luna (ルナ, Runa): The Luna Memory, also known as the Illusion Memory (幻想の記憶, Gensō no Kioku), allows the user to cast illusions, stretching limbs and bending gunshots, becoming the Mysterious Warrior (神秘の戦士, Shinpi no Senshi). When used, half of Kamen Rider Double becomes the gold Fantastical Right Half (幻想の右半身, Gensō no Migi Hanshin).

The Fang Memory (ファングメモリ, Fangu Memori), also known as the Fanged Memory (牙の記憶, Kiba no Kioku), is a special Gaia Memory built to protect Philip and act on his orders, able to change between its Dromaeosaurid-like Live Mode (ライブモード, Raibu Mōdo) to Memory Mode (メモリモード, Memori Mōdo). Philip uses the Fang Memory to transform into Kamen Rider Double's FangJoker (ファングジョーカー, Fangu Jōkā), becoming the body while Shotaro's consciousness is transferred into him. While this allows Philip to go out into the open and utilize Double's power in case Shotaro is physically unable to, the form tends to be a last resort as the transformation is extremely taxing on Philip's frail body while rendering him a berserker. Able to produce the bladed weapons on his body like the Arm Saber (アームセイバー, Āmu Seibā) and the removable Shoulder Saber (ショルダーセイバー, Shorudā Seibā), and the Maximum Saber (マキシマムセイバー, Makishimamu Seibā) used in FangJoker's Fang Strizer (ファングストライザー, Fangu Sutoraizā) Maximum Drive.

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 head of 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 didn't hear of this!!!" (私聞いてない!, Watashi 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 春奈, 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]

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 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 Net (スパイダーネット, Supaidā Netto) 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 is portrayed by Tarō Yamamoto (山本 太郎, Yamamoto Tarō).[4]

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" (マッキー, Makkī) by Shotaro and the others.

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

Ryu Terui[edit]

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.

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.

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.

The Dopants (ドーパント, Dōpanto) are humans who received Gaia Memories from the Museum. Originally, the Gaia Memories were created by using Philip's link to the true Gaia Memory (地球の記憶, Chikyū no Kioku) by means of the Gaia Library (地球(ほし)の本棚, Hoshi no Hondana). But after Philip was taken, Ryubee resorts to using a shrine located under the Sonozaki manor to create Gaia Memories. From there, the Museum would sell them to the highest bidder or to common criminals, both types used as guinea pigs to study the Gaia Memories as part of the Gaia Impact project. Despite the Museum organization being disbanded with Ryubee's death, some Gaia Memories are still unaccounted for.

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 created throughout the criminal underworld for experimentation, resulting in the Dopant crime waves. The ultimate goal of Museum is to use the data gathered for both the Dopants and the Kamen Riders to invoke an effect known as the Gaia Impact (ガイアインパクト, Gaia Inpakuto), which Ryubee plans based on his fears of humanity's extinction to make mankind one with the Earth itself.

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 corruptive effects of usual Dopant Gaia Memories at the cost of reduced power. 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, Āru 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 Shisakutai 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.

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.

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.

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.

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).

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.

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.

Though much stronger, faster and more durable than normal humans, the downsides for Necro-Overs is their ability to feel emotions diminishes with time, gradually rendering them increasingly undead-like, while requiring regular bio-stabilizer injections to keep their bodies intact. When Foundation X abandoned them in favor of the higher diversity presented in Gaia Memory research, the NEVER became mercenaries while leaving a path of destruction in their wake to proof themselves superior to the Museum's "toys". But an encounter with Doctor Prospect drove their leader insane as the group destroy the Museum by obtaining the T2 Gaia Memories, which they use themselves, to power the X Bicker (エクスビッカー, Ekusu Bikkā) and covert residents of Futo residents into Necro-Overs. While Necro-Overs display exceptional compatibility with certain Gaia Memories, they are greater risk than normal humans as being struck with a Maximum Drive or Kamen Rider OOO's Scanning will cause the Necro-Over to disintegrate. They can become destabilized if injected with a bio-stabilizer blocker fluid, which reversible if the Necro-Over quickly administers an antidote.

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.
