In the ecologically-minded city of Futo, there are many windmills and 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 hardboiled (actually half-boiled) detective Shotaro Hidari works with the mysterious Philip, who possesses the true Gaia Memory, to investigate crimes which involve Dopants. Dopants are normal humans who use Gaia Memories. The Gaia Memories are aspects of the true Gaia Memory, the knowledge of everything on the Earth. These were originally accessed due to Philip's link to the Gaia Memory by means of the Gaia Library. But after he was taken from them, the Sonozaki Family uses a strange temple underneath their mansion to access the Gaia Memory. They then sell these 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. 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.
