This series premiered in 2009 after the finale of Kiva and was billed as the 10th anniversary of the Heisei Rider Series, lasting for only 31 episodes. Tsukasa Kadoya is a photographer with no memory of his past and whose photos never turn out quite right. When dimensional portals open up, trapping his only friend Natsumi Hikari with the various monsters other Kamen Riders have faced, she finds the Decadriver which Tsukasa instinctively uses to transform into Kamen Rider Decade, a being Natsumi has seen in her nightmares. While the world seems to collapse around him, everything freezes and he is approached by Wataru Kurenai who tells him that the multiverse is collapsing, and this world will be destroyed unless he travels to the worlds of the other Kamen Riders and fix them in order to prevent the destruction of every world. However, the mysterious Narutaki disseminates rumors throughout the other realities that Tsukasa will be the destroyer of all worlds, causing the Kamen Riders to turn on him.
