Furthermore, Ora has created Another Den-O after finding a suitable target: a man who is jealous of his sister's lover...

Continuity and Placement

 * Kamen Rider Den-O: After the events of Kamen Rider Heisei Generations FOREVER. However, since Sougo doesn't remember the DenLiner, Another Den-O, and Imagin, the film might as well be non-canon, as previously stated by the show's producer Shinichiro Shirakura.

Plot
"Apologies, it seems I may have spoiled a future of what's to come. Please forget what you saw. However two individuals seems to have their eyes set on Sougo Tokiwa from the shadows. Just who would they might be? Let us return to the story, to when two Watches remained have yet been collected..."
