List of Kamen Rider W episodes

The Nasca Dopant and Kamen Rider Double FangJoker fight, and the Nasca Dopant has the upper hand with his newfound super speed powers until he suddenly falls in pain. Philip is ready to deliver the finishing blow until Shotaro stops him, saying that killing him would not be right, citing the Futo-kun poster on a nearby wall and Kirihiko's love of Futo as a reason. Double and the Nasca Dopant end the fight and go their separate ways as Shotaro takes Toma to the hospital. Later at the Agency, as Akane blames herself for Toma, Philip returns from the Gaia Library and reveals the real Living Connector on Akane. She tells them that after she was having problems completing the high jump at school in preparation for an event, a woman approached her and gave her the Bird Memory to help. Later, as Akane rests, Shotaro leaves to contact Akane's father that they have found her. However, Akane wakes up and attacks Philip and Akiko in a withdrawal rage before running off with one of the Spider Shock's trackers attached on her. Akane returns to the school where she comes across Saeko, the woman who had given her the Living Connector in the first place, and the Bird Memory is returned to Akane. At the Sonozaki Family mansion, after seeing Saeko coming out of a secret doorway, Kirihiko enters it and finds himself in an underground cave system with a strange piece of equipment within it. Ryubee reveals it to be the source for the first set the Gaia Memories and the center of the Museum. Furthermore, Kirihiko learns that Ryubee intentionally allowed the Bird Memory to be given to children to test the new Gaia Memory's power, regardless of the consequences. An enraged Kirihiko threatens to kill Ryubee as the Nazca Dopant unless he is told how to defeat the Dopant without harming the child. But once he learned the answer, he begins writhing in pain as Ryubee explains that because he is also used to test the Nasca Memory's powers, revealing that its Level Two power is slowly killing him. Ryubee then transforms into the Terror Dopant to put him out of his misery as the Nasca Dopant escapes to only be chased by the Smilodon Dopant. But Wakana arrives and turns into the ClayDoll Dopant to save Kirihiko. Kirihiko thanks Wakana as she tells him to be true to himself, leaving to help the Kamen Rider with the knowledge he gained. By that time, Shotaro finds Akane just as she uses the Bird Memory and flies away. Shotaro and Philip transform to give chase, eventually summoning the RevolGarry to use the HardTurbuler to chase her in the air. During the fight with the Bird Dopant, she evolves into a stronger form and knocks Kamen Rider Double out of the HardTurbuler. Double changes into CycloneTrigger and tries to hold off the attacks until the Nasca Dopant appears to help by knocking the Bird Dopant out of the air and reveal its weak point with his Driver. Akane is freed after the Trigger Bat Shooting and the Nasca Dopant regresses into a pain stricken Kirihiko as reveals Museum's existence to Double before giving him his Futo-kun keychain and leaves. Later, Kirihiko calls Saeko and asks if she would leave town with him out of love. Saeko, in response, transforms into the Taboo Dopant and blasts him with one of her energy balls, taking the Nasca Memory and saying that she has bigger plans for the Gaia Memories. As she leaves, Kirihiko feels the breeze and disappears into a cloud of dust that drifts away in the wind.

Just as Kamen Rider Accel prepares to attack Makiko, Kamen Rider Double HeatMetal intervenes allowing Makiko to escape. Enraged that Double's getting his way of executing owner of the W Gaia Memory, Accel forces him to revert and was about to kill Shotaro for his ideology until Akiko stops him. Ryu leaves after admitting that he hates Futo and sees no good in it. As Shotaro refuses to accept Ryu's ideology and heads out, Philip decides to investigate Ryu's relation to the W Gaia Memory in the Gaia Library. While Ryu follows Kiyoshi to his mother, Shotaro goes to see Watcherman for information on Makiko. Shotaro arrives just as Accel is about to kill her with Philip helping her escape. Forming Kamen Rider Double FangJoker, Philip manages to subdue Accel before revealing he knows about Ryu's family being killed by a Dopant with icy powers. Enraged that his past is revealed, Philip asks Ryu to tell him what had happened. Ryu tells how his father, before he died, told him that his family's murderer was a man with a Gaia Memory with the letter W. Ryu met Shroud soon after, receiving the Accel Memory and Engine Blade to get his revenge. Before he walks off to find Makiko, Shotaro informs him that she is not the Dopant. Taking Ryu to a dance club, Shotaro reveals Kiyoshi to be the icy Dopant and that his mother has only been protecting him. Suddenly, Makiko arrives, pleading for Kiyoshi to stop, but he shoves her off and escapes as the icy Dopant. After telling Makiko not to burden herself, Shotaro and Philip give chase as Ryu begins to contemplate how Shotaro kept him from making a big mistake. As HeatJoker and then HeatTrigger, Kamen Rider Double has trouble with the icy Dopant's abilities and is overwhelmed until Ryu appears once more and transforms into Kamen Rider Accel. Using the Engine Memory's Steam abilities in the Engine Blade, Accel deflects the Dopant's attacks before using a Maximum Drive to expel the Gaia Memory from Kiyoshi. After nearly giving Shotaro and Makiko a fright, everyone is surprised as Ryu slaps handcuffs on Kiyoshi instead of attacking him, stating that he will play by Shotaro's rules while in Futo. As Makiko comforts her son, Ryu picks up the Gaia Memory and realizes that it is the IceAge Memory, and not the W Memory.

Queen and Elizabeth approach Shotaro as clients to investigate the goings on at the Fuuuuuutic Idol competition. While performing their song "Love♡Wars" to get a major release, the audience loves them but for some reason the three judges –Aya Kamiki, TAKUYA, and Ichirouta Oonuki (Ichirou Mizuki)– eliminate them in favor of street musician Jimmy Nakata whose singing is terrible, blaming an individual known as the "Radio Tower Clown" for their failure and his promotion. Though warned by the two informants, when Shotaro and Akiko investigate Jimmy, they reel in pain from his painful singing of his song "Futo Tower" (風都タワー, Fūto Tawā^?). Shotaro begins asking him about his "spilk" (スピック, supikku^?, "spinning to folk") style until his fan Yukiho Sumita barges in, asking for another of Jimmy's autographs. At the Sonozaki Mansion, after Ryubee sees Saeko heading off to see the W Memory owner, Wakana turns on the TV to watch Fuuuuuutic Idol as Jimmy wins his second win to the audience's distress. When Ichirouta Oonuki steps up to the stage to call on an audience member to perform: Philip in a yellow mask. Shotaro tries to stop him, but he hands Shotaro a blue mask and Philip dubs themselves the "Kamen Singers". As the duo perform "Finger on the Trigger", Ryu confronts the "Radio Tower Clown" and fights him as Kamen Rider Accel behind the scenes, supposedly destroying his Gaia Memory with the A-Slasher. After Shotaro and Philip's performance, they too are eliminated in favor of Jimmy Nakata. Though Shotaro tells him the contest is fixed, Jimmy does not believe it. At the Narumi Agency, Ryu states that the "Radio Tower Clown" is a Dopant who was responsible for Jimmy's wins and holds up the destroyed Gaia Memory to prove it, only to find out what he had picked up earlier is actually junk and not a broken Gaia Memory. While Philip helps Ryu track down the Gaia Memory, Shotaro attempts to find Yukiho, who he believes is responsible. However, he instead finds poet and street calligrapher Sachio Sawada before Santa-chan tells the two that Yukiho works at a recycling plant. They two watch her from afar before Yukiho passes out, taking her to the Isaka Internal Medicine Clinic where she reveals her intent to do anything for Jimmy. They pursue her when the strange Dopant appears with Yukiho paying him for help. However, feeling that he is not being paid enough, the Dopant refuses to help her anymore. Accel arrives, revealing that their opponent is the Liar Dopant and how he has manipulated the judges into making Jimmy win. After Shotaro transforms, Kamen Riders Double and Accel double-team the Liar Dopant until Yukiho interrupts Double LunaTrigger as he prepares the Maximum Drive. As Yukiho pleads that she needs the Dopant to help Jimmy win, Jimmy arrives as the Liar Dopant has arranged, revealing the lie to him. Upon realizing his success was all a farce, he breaks down in tears.

After the Liar Dopant's ruse is revealed, Jimmy breaks down in tears. When Kamen Rider Double's guard is down, the Liar Dopant uses Lie Needles to trick Double into thinking Accel is a Dopant and then redirects Akiko's slipper attack to a tanuki statue. Before he leaves, the Liar Dopant gathers some of Jimmy's tears on a slip of washi paper. The Lie Needles' effects wear off soon after, as Jimmy leaves in a huff with Yukiho in tears. While this all occurs, Dr. Isaka examines Saeko's Dopant form, suggesting to her that she could possibly defeat her father and take over the Museum, offering his services to her. Back at the Narumi Agency, Yukiho reveals how she met Jimmy while in a deep depression and his singing was the only thing that brought her joy. Wanting to return the favor, she says she met the Liar Dopant, who convinced her that he could help Jimmy win the Fuuuuuutic Idol competition. As Ryu and Philip review their battles with the Liar Dopant, especially how the Lie Needles affect them, Shotaro finds Jimmy at the beach and, in an unwilling melodramatic fashion, tells the young man that he has been lying to himself the whole time and now needs to make his own choice. Using washi as a keyword, Philip identifies the Liar Dopant as Sachio Sawada. However, after Shotaro finds Sawada has gone into hiding, Ryu recites something the Dopant said to him, which Philip identifies as one of Wakana's catchphrases. Phoned by Philip, Wakana agrees to help him by claiming she would meet the "Radio Tower Clown" after finishing her broadcast. Hearing it on the radio, Sawada assumes his Dopant form and follows her. When he finds Wakana meeting with the "Radio Tower Clown", the "Clown" directly insults Sawada, bringing the Dopant out of hiding. However, it turns out to be a trap as Shotaro is the "Clown", Ryu is Wakana's bodyguard, Akiko is one of Wakana's (male) fans, and Philip is Wakana. While Akiko is distraught that she had to play the male fan while Philip played a very convincing female role in the trap, Kamen Riders Double and Accel battle the Liar Dopant, with Double assuming CycloneMetal form to use the Spider Shaft combo to disable the Liar Dopant's needle attacks. After being saved by Accel in Bike Form, Double uses Accel's speed to deliver a Joker Extreme to destroy the Liar Memory, bringing Sawada to tears. Back at the studio, with Yuhiko in the crowd, Jimmy arrives and dedicates a song to her which the judges dislike (now that the Liar Dopant's spell is over), but they admit that he put a lot of heart into it and they encourage him to work harder. Backstage, Yukiho approaches Jimmy and they admit their feelings to each other.

After the destruction of the Sonozaki mansion, Shotaro and Akiko present Philip with Mick, who they have found to cheer him up. However, Philip reveals that Wakana is still alive due to the link they made and asks Shotaro to help him find her no matter what happens. While this occurs, the leader of Foundation X, Neon Ulsland, presents the Charming Raven pharmaceutical factory to Jun Kazu to serve as their own Gaia Memory factory as the Museum's funding has been severed in favor of a new project. Kazu reveals that the Museum still has use for them as he reveals that Wakana has been salvaged to complete the Gaia Impact after her body fused with the ClayDoll Memory, and he has someone planned to take over organization. Elsewhere, Shotaro has had Watcherman find Saeko, the person he believes has taken Wakana. They and Ryu find her at the local race track on her motorcycle, only to find Saeko is surprised to hear her sister is still alive. Suddenly, Kazu appears to escort Saeko, introducting himself and revealing that Foundation X has been behind the Museum all along and now is heading the Gaia Impact project. Philip demands that he free Wakana, but Kazu refuses and shows that he has a Gold Memory as he uses it to become the Utopia Dopant. Everyone is lifted into the air until the transformation completes and Ryu transforms into Kamen Rider Accel to fight him. Shotaro prepares to transform, but Philip tells him that they should hold off until they have the chance to save Wakana, as the next time they become Kamen Rider Double, Philip will disappear forever. Accel is easily defeated by the Utopia Dopant's reality altering powers as he takes Saeko with him to the Foundation X headquarters, with Saeko telling Philip that their father must be rolling in his grave. As Saeko is introduced to Ulsland, she learns that the Foundation plans to digitize Wakana into data and beam her into the Foundation's satellites to eliminate all humans on Earth who are not highly compatible with Gaia Memories. As Ulsland leaves to another appointment, Kazu gives Saeko the Taboo Memory. Back at the detective agency, thanks to Saeko giving him the clue in saying "grave",
