Ep. 1: The Earth Federation Alliance battles Zeravire while Eiji and Luna recall Toga's past.
The Earth Federation Alliance deploys new Gran Troopers, piloted by Alex Smith and Faye Xin Lu, to intercept Zeravire. Meanwhile, Eiji and Luna, having lost a Mahjong bet to castle maids, work in the kitchen. Sandman, who has been attending global conferences, is absent from the castle. An emergency warning signals the Zeravire's approach, prompting Eiji and Luna to discover Toga's childhood room. Luna recalls their first meeting and regrets not giving Toga a photo album. The G-Soldiers and Gran Knights launch to intercept the enemy. The Federation forces fail due to a lack of gravity power. Toga's attack is repelled by the Zeravire's shield. Without Sandman, Gran Kaiser cannot activate Elgo Mode to form Gravion. Sandman contacts the team from a grounded airport, allowing Gravion to combine. It destroys the Zeravire using the Double Pressure Punch. On Llambias, Hugi tells his sister Lufira that it is time to remake the planet.
