Story

In the ecologically-minded city of Futo (風都 Fūto^?, the "Windy City"), where nearly everything is powered by windmills, the people live in harmony. However, the Sonozaki Family sell mysterious devices resembling USB flash drives called Gaia Memories to criminals and other interested parties who use them to become monsters called Dopants, committing crimes with the police force powerless to stop them. To make matters worse, the Gaia Memories carry a dangerous toxin that cause their users to go insane to the point where they could die from the life-threatening devices. After the death of his boss, the self-proclaimed hard-boiled (actually half-boiled) detective Shotaro Hidari works with the mysterious Philip, who possesses the true Gaia Memory, to investigate crimes which involve Dopants. Using their own Gaia Memories, Shotaro and Philip use the Double Driver belts to transform and combine into Kamen Rider Double to fight the Dopant menace and keep Futo safe. While joined in their fight by investigator Ryu Terui, who transforms into Kamen Rider Accel, the mystery of Philip's past, his relation to the Sonozaki Family, and their Museum organization are revealed.^[2][9]

Wind Wave Internet radio

Main article: Wind Wave FM

To tie into the show, TV Asahi, Toei, and Avex Trax have produced the Wind Wave FM Internet radio station. Only one of the shows, Wakana's Healing Princess (園咲若菜のヒーリングプリンセス Sonozaki Wakana no Hīringu Purinsesu^?), also exists within the fiction of Kamen Rider W. The other programs, DJ Hurry Kenn's FU-TO Hit on Groove music show and Tsuyoshi and Ayano's Head Wind: One-Game Match!! (向い風 一本勝負!! Mukaikaze Ipponshōbu!!^?) show, treat the television series as fiction, explicitly referring to the songs they play as theme songs (as part of a mail in request, DJ Hurry Kenn played AAA DEN-O form's "Climax Jump", and referred to it as the theme song for Kamen Rider Den-O). All of Double's theme songs have been played as part of the various radio shows, several of which were first heard on the "radio" before being utilized as part of an episode's soundtrack. On March 7, a new radio show featuring Queen & Elizabeth titled Queen & Elizabeth's White Hearts!! (QueenとElizabethの白抜きハートマーク!! Kuīn to Erisabesu no Shironuki Hātomāku!!^?) began "airing", but was discontinued a month later. To mirror the current events in the show's story, Healing Princess was cancelled on June 13, 2010.

These feature a Dopant from the DVD volume in a completely different role than it had in the series proper. These are then followed by members of the cast discussing their favorite parts of the episodes included on the DVD volume.
