Decade re-imagined

- Kadoya Tsukasa is an amnesiac Photographer who only knows that he is Decade and must restore the 9 rider cards to have enough power to stop an impending threat.

- To restore the rider cards he must find the 9 riders and simply just get their data to be the ultimate rider. But there is only one problem.... all of the riders sacrificed themselves years ago to save Earth and are nowhere to be seen. It is not until he meets Onodera Yuusuke that he can extract Rider Data by temporarily giving certain people who exhibit traits of the past riders the ability to become Kamen Riders.

- Yuusuke is the Phillip/Ank/Kengo/Shunpei of the show who also happens to help Tsukasa find out about the "Kamen Ride" system that allows civilians to become riders temporarily.

- After Yuusuke and Natsumi form a trio with Tsukasa, the following episodes would follow this format until Tsukasa gets all cards with the help of Yuusuke and Natsumi going place to place helping the victim of the week by letting them be a Kamen Rider while Tsukasa gets data in return. Narutaki would be pretty much the same always "ONORE DIKEIDO"ing Tsukasa for some reason.

- Second and final arc would be where Tsukasa finds out his true past and gets all of his Rider Cards stolen by the true villians as well as Natsumi. We are then introduced to Diend, who actually has a complete collection of non-protagonist riders (i.e. Knight, Garren, Gatack, etc.) at his disposal. Instead of the thief character we all know, Daiki is a rider gone rogue who works with Narutaki to stop Foundation X.

- Tsukasa's past and identity as a sleeper agent is revealed through Foundation X, and Narutaki realizes that the Decade that he has been cursing is not Tsukasa, but Foundation X's Ultimate Rider a.k.a Dark Decade who was thought to have been destroyed by the former Heisei Riders.

- Tsukasa then goes into a personal struggle until he is helped by the 9 people who he has gathered data from. Tsukasa and the 9 new riders including Yuusuke will then become the 10 Kamen Riders ensuing in a brawlfest with Dark Decade and Foundation X. Tsukasa acquires Complete Form thanks to Daiki who stole the by-product of Tsukasa's data-mining a.k.a. the K-Touch, and finishes off Dark Decade while Foundation X runs away. Tsukasa saves the day and rescues Natsumi.

- In the end, Tsukasa decides to go on a journey to find out more about his past and see if he can unveil more about Foundation X. Natsumi and Yuusuke decides to tag along which he allows.

After end credits roll, Foundation X remnants target their next base of operations using Gaia Memories as Fuuto.
