After millions of years, the Deboss Army has returned to attempt to wipe out the world of man, after having nearly succeeded to do so to the world of the dinosaurs.

Standing in their way is Daigo Kiryu, who has been tasked to first find and battle the ZyuDenRyu Gabutyra so he can become one of the Kyoryugers.

Plezuon's warrior Kyoryu Violet appears, revealing he has lost Plezuon on a mission to space half a year ago. The current Kyoryugers demand to get him back, so they seek out the help of a scientist.

Yayoi reveals she has planned to install data into Plezuon that will allow it to defeat Deboth, as it went to investigate a planet that was destroyed before Deboth came to the Earth. However, the Deboth Army plans for this and hopes to speed up the resurrrection of their leader on a particularly rainy day.
