|This article is about a/an A.R. World (another rider's world) in Kamen Rider Decade.|
The World of Den-O (電王の世界 Den'ō no Sekai) is the version of reality in which Kamen Rider Den-O supposedly takes place. The backdrop used to enter this world depicts the DenLiner moving across the sands of time, which Ryutaros doodles on later in the episode arc. Within this world, Tsukasa finds himself wearing a trenchcoat and bucket hat, the same clothing as the Past Man and given abilities similar to those of a Singularity Point. Daiki's treasure in this world is the DenLiner.
The World of Den-O arc coincides with theatrical release of Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship, which takes place within the continuity of Decade like Kamen Rider Den-O: I'm Born! did with Den-O. And later Daiki returns to the World of Den-O to settle things with Reiji Kurosaki who transforms into Kamen Rider G Den-O in Episode Yellow: Treasure de End Pirates, part of Kamen Rider × Kamen Rider × Kamen Rider The Movie: Cho-Den-O Trilogy. His treasures are the pistol heirloom from the Kurosaki family and the Diend K-Touch which transforms him into a Complete Form.

In the novel reimagination of the Kamen Rider Decade TV series, Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~, the World of Den-O is, as one of the Nine Worlds, is just like in the TV series, the original world. Having already traveled to six worlds, the World of Den-O is the first of the three remaining worlds the Hikari Studio group, Tsukasa/Decade, Kaito/Diend, and Natsumi, explore during the novel.
Tsukasa’s clothes change into a doctor’s uniform as they arrive in Den-O's World. Tsukasa meets Ryotaro Nogami, but his Imagin friends are missing. Tsukasa agrees to help him find them. The Den-O characters feel very off-character as their characteristics are different. Momotaros comes off as rather polite compared to his jerkish and self-centered TV counterpart, and actually refers to people by their real names instead of snarky nicknames. The Final Form Ride remains the same, as Tsukasa turns Den-O into Momotaros.
