PlotEdit

The story revolves around the nine previous universes of the Heisei Kamen Riders merging into one, something that would destroy all the worlds. To prevent this, Tsukasa Kadoya transforms into Kamen Rider Decade and is told that to protect his own world he must travel with Natsumi and her grandfather to the other Kamen Riders' Worlds (referred to as an A.R. World or Another Rider's World) and eliminate the anomaly in that world. Along the way, confronting the mysterious Narutaki and the thief Daiki Kaito, they are joined by Yuusuke Onodera of the World of Kuuga and Kivala of the World of Kiva.

Rider WarEdit

The Rider Army (ライダー軍, Raidā Gun?), first revealed in Natsumi Hikari's dream, composed of many Kamen Riders, all of whom where seemingly defeated by Kamen Rider Decade. However, Kamen Rider Kuuga survived the initial battle, assuming Ultimate Form to confront Decade once again with the two seemingly destroying each other in the ensuing battle. As Narutaki explains to Natsumi, the dream is a predestined event in which Decade will destroy all the worlds.
