Prelude to the SiegeEdit
Tsukasa Kadoya, also known as Kamen Rider Decade had overseen Samus's activities in the present time where she connects with other Riders besides him. Tsukasa decides to travel to the future not only to destroy her world, instead starts with the Galactic Federation. Tsukasa returns to the Hikari Studios, a photography studio where he works and is a place that allows him to travel into different parallel worlds. However, the Rider Cards containing Kamen Riders Double to Drive allowed Tsukasa to travel into the future, and so tags along with Kaito, and the Ganma Prince, Alain.
When Narutaki meets the Hikari Photo Studio crew, he joins with Decade's plan to lure the Federation to a trap; using the dimensional doorways as a medium, luring a Federation infantry in sight to their doom.
