The Dragozaurs' base begins to crumble without a supply of life force, and Diamond Ryugu sends Drago Wing to Earth to command an army of bite lice to invade and cover it with dark energy. The Dino Knights are disabled, and so Kaito, Rena and Rick venture out to stop the lice. However, they and the Dino Knights are unaware that the lice are just to distract them from Diamond Ryugu's true plan.
