Kishiryu Sentai Ryusoulger

65 million years ago, the knights of the Ryusoul Tribe were chosen to wage war against the dictating Druidon Tribe, whose goal was to rule Earth. But the Druidon’s campaign was halted by the meteor that brought the age of the dinosaurs to an end, forcing them to flee into space. Meanwhile, the Kishiryu were sealed in a deep sleep as a failsafe should the Druidon return. The chosen knights chose to live in peace, handing their mantle down through generations. In the present day, the Druidon return to reclaim Earth, and the current generation of knights, the Ryusoulgers, battle them with the support of Ui Tatsui and her father Naohisa Tatsui.
