Ep. 2: Eiji and friends visit Sandman's castle, leading to a chaotic picnic and a runaway G-Driller incident.

Eiji’s friends discover a map on the Earthgertz website and travel through a jungle to reach Sandman’s castle. Inside, they find the pilots exercising, and Eiji confronts them about the Gran Divas’ role in defeating the Zeravire. Eina and the maids provide a tour of the hangars and control room, where Sandman announces a picnic. The pilots bring the Gran Divas along for protection. During the event, Mizuki attempts to flirt with Raven, while Eiji notes he has not seen his sister. Kaori accidentally activates the G-Driller, launching herself and Yumi into the sky. The team pursues them, and Sandman rides his horse to catch up. He uses a crystal to reset the G-Driller and combine it with Gravion. Finally, the Earth Federation Alliance President examines an eighteenth-century painting of Sandman, identified as the alchemist Count Saint-Germain.
