Novel: Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~ (小説 仮面ライダーディケイド: 門矢士の世界~レンズの中の箱庭~, Shōsetsu Kamen Raidā Dikeido Kadoya Tsukasa no Sekai~ Renzu no Naka no Hakoniwa~) is part of a series of spin-off novel adaptations of the Heisei Era Kamen Riders. Similar to Agito and Kiva, this novel is the reimagination of the TV Series.

The novel itself is 248 pages long, with 8 chapters and is a parallel universe. It does not follow what happened in the TV series. Throughout the novel, Tsukasa Kadoya, Natsumi Hikari and Daiki Kaito travel to 3 different worlds while stopping at Tsukasa’s world in between every world. The group has already traveled to 6 different worlds when the novel begins, leaving only Den-O, Kuuga and Kabuto’s world to be explored. The worlds he travels to are supposed to be the original worlds. The novel was released on April 12, 2013.

Summary[]

Tsukasa Kadoya is generally the same personality wise. His world is different from the world in Kamen Rider Decade: All Riders vs. Dai-Shocker movie. He has no sister and his parents live overseas. In the novel he’s described as a young NEET (Not in Education, Employment, or Training) tired of his mundane life, the only thing he finds interesting is photography. He ends up stumbling upon an abandoned photo studio, inside he finds an old camera standing on a tripod. Tsukasa picks it up and peeks through the viewfinder. Through the viewfinder, Tsukasa sees a completely different world. The photo studio isn’t some ordinary photo studio that was just abandoned. It actually manifests itself in front of people that are tired of their own world and want to find a new world. Natsumi, Kaito and Narutaki, all found the photo studio in their own respective home worlds.


Tsukasa meets Natsumi in the first unnamed world he traveled to. A world where monsters are attacking humans. Natsumi sees this and calls Tsukasa by the name ‘Decade’ and gives him the Decadriver, telling him he must transform. A confused Tsukasa goes along with it and becomes Decade for the first time. They travel to another world together and meet Daiki Kaito. He acts hostile towards Tsukasa, but still decides to follow the two on their travels. Narutaki appears in every world the trio went to, yelling at Tsukasa, calling him the Destroyer of All Worlds (though it was actually Narutaki himself) and he’s really mad at him.

The novel doesn’t reveal much regarding the other 6 worlds they’ve already traveled to and jumps straight ahead to Den-O’s world. Tsukasa’s clothes change into a doctor’s uniform as they arrive. Tsukasa meets Ryotaro Nogami, but his Imagin friends are missing. Tsukasa agrees to help him find them.

Kuuga’s world is set somewhere early in the TV show, where Kaoru Ichijo is the only person who considers Kuuga to be an ally of humanity, while the rest of the police forces consider Kuuga as a threat. They team up with Yusuke Godai, who refers to Tsukasa’s transformed identity as “Dickens.” In this world, Tsukasa is dressed as a painter, an identity in which he meets a mysterious unnamed girl, with her sentences spoken in broken grammar. This girl approaches different men saying “Do you want me?” The girl is referred as Yuri after Tsukasa sees her holding a lily flower, yuri in Japanese. She asks the question to Tsukasa, but Natsumi doesn’t like it and uses her Laughing Pressure Point technique. Yuri takes a liking to Tsukasa and connects with him. Tsukasa says they are the same type of people, and relate to each other. But he reveals that he never really paid attention to her and never cared about her. From the start, Natsumi oddly suspects that Yuri is a Gurongi who causes people to explode by sticking moth scales from her wings on people. Decade and Kuuga defeat her together. Godai gives Tsukasa a thumbs up as they leave.

They shortly move onto the world of Kabuto, where they meet Soji Tendo, still as arrogant and confident as ever, and considers himself as the strongest Rider ever. The group enters Bistro La Salle where Hiyori Kusakabe works. Hiyori sees Kaito and Tsukasa, dressed as ZECTroopers, claiming that the two of them ate without paying. Tendo hears this and is enraged. The three of them fight and Tendo actually beats them with only a pair of chopsticks. Turns out it was a pair of Worms that ate without paying. Tsukasa and Kaito are eventually captured by ZECT, only to have Tendo save them. Tsukasa thanks him and says that he never thanks people. Tsukasa starts respecting Tendo. Tendo presents the Clock Up AttackRide Rider Card to Tsukasa after he realizes that he is Kamen Rider Decade. In the end, the Worms that impersonated both Tsukasa and Kaito are defeated. As the fight is over the trio goes back to Tsukasa’s world.

Between all the traveling, a vampire has been attacking in Tsukasa’s world, leaving behind drained corpses. The group investigates and they find out that Narutaki is the vampire. Just like the group, Narutaki originally had his own homeworld, but abandoned it to find a new one. However, he’s been traveling for so long that his mind has been deteriorating and can barely remember who he really is. He was originally a human, but somehow in his journeys, he had lost his humanity. The Kamen Riders have a very pure energy that Narutaki seeks to consume: the Rider Cards. Thus, he sends Kaito, who wishes to help create the new world after his family was murdered by a crook who subsequently walked, to steal them for him. Kaito reveals his betrayal towards the team and gives Narutaki Tsukasa's 9 Heisei Rider Cards and Narutaki reveals his real form: a red-hued demon.

Kaito suddenly has a change of heart, and sacrifices himself to save Tsukasa. All hope seems to be lost; Tsukasa even uses a Diend card with the DecaDriver. While it turns him into a cyan-hued version of Decade, armed with a gun. However, he was badly overpowered by Narutaki and reverts into human form again. Natsumi, who had just realized that she has special powers all along, creates a special Kamen Ride card with the 9 previous Heisei Riders on it. Tsukasa uses it, which summons the previous 9 Heisei Riders to perform their finishers onto Narutaki. They then turn into Kamen Ride cards and attached themselve onto Decade, turning him into Final Kamen Rider Decade, Tsukasa then finishes off Narutaki via a Rider Kick. In his dying words, Narutaki laments that he wanted to destroy all worlds and then create his own ideal world. He dies looking at Natsumi, knowing that she had the power to do what he wished for.

With the crisis over, Tsukasa returns to his world and Natsumi decides to go with him and live in his world. When they return, Tsukasa, having found an article where it says Tsukasa's world version of Natsumi had died after committing suicide due to worldly troubles years prior, wonders when she will be forced out to return to her own world.
