Spoilers for the Kamen Rider Decade novel entitled, "The World of Tsukasa Kadoya ~The Garden Inside the Lens~" has surfaced online. The novel is written by Aki Kanehiro, and this is his debut work according to Toei producer Shinichiro Shirakura.
Spoiler alert! Read at your own risk!
The Decade novel will feature the original Riders, or might be the original Riders because the novel uses the names Godai and Tendou. Even if that is the case, the novel is full of errors, there is one point in the novel that there are two Ryutaros, and Kabuto transformed into the Gouram. Decade also gains two new "forms", and lastly, Narutaki is a vampire.
To put it simply, the novel is bad, really bad.
