Meanwhile, the Kishiryu were placed in a deep sleep as a failsafe should the Druidon return. The chosen knights choose to live in peace while passing their mantle down across generations. In the present day, the Druidon return to reclaim Earth as the current generation of knights, the Ryusoulgers, battle them with the support of Ui Tatsui and her father Naohisa Tatsui.
