Sentou, Banjou and Kasumi fight their way deeper into Pandora’s tower, while Sawa and Misora uncover some shocking truths about Banjou’s past.
Sentou has the government declare him an outlaw so he can take the fight to Seito directly. Also Misora is an alien now! So is Banjou!! And maybe Soichi too??? Who even knows anymore!
All out war erupts between Seito and Touto as Stark begins to use the power of Pandora’s Box to build a mighty tower.
Sawa reveals she was the mole amongst the good guys (again!) but fortunately Sentou has devised a cunning backup plan.
Our heroic Kamen Riders find out that Seito is putting on another winner-takes all Proxy Battle. Everything comes down to the final round between Build and Rogue.
Our heroes are saved from the rampaging Rogue by Misora’s sudden awakening to mysterious powers, but Gentoku is still determined to get his hands on Pandora’s Box.
With seemingly unlimited power at his disposal, Gentoku leads the invasion of Touto, forcing Build and Grease to team up in an attempt to put him down.
