|“||The time for revolution is now!||„|
|~ Shingo Kuwata before transforming into the Flying Smash.|
|“||Takumi Katsuragi is alive!||„|
|~ Shingo Kuwata's last words.|
A researcher at the Touto Institute of Advanced Matter Physics, Shingo Kuwata was a colleague of Sento Kiryu and secret member of Faust who later took part in Faust's theft of the Pandora Box
Kuwata's role was to lower the security around the Pandora Box, but Sento Kiryu interfered. Kuwata then turned himself into a Flying Smash to fight Build, but was defeated by the Rider in his LionCleaner form and reverted back to his normal human form.
After his defeat, Kuwata revealed that he was really a distraction for Sento while Eita Kawai stole the Pandora Box. He then used Nebula Gas to commit suicide, proclaiming that Takumi Katsuragi, the "Devil's Scientist" was still alive before dissolving.
