Ep. 7: Luna visits Okinawa for her father's grave and fights a Zeravire with the G-Driller.

Luna travels to Okinawa, her birthplace, to visit her father's grave one year after his death on a mission to detect the Zeravire. An old family friend urges her to stay longer. At the beach, the G-Driller emerges from the sand with Eina inside. The entire team arrives, having been ordered to relax by Sandman. During a meeting between world leaders about the Zeravire at the International Peace Center, a Zeravire bursts through the floor. Leele senses its presence, and Mizuki receives a message to activate Gravion. Gravion moves to the Peace Center, but the Zeravire is gone. It suddenly bursts through the ground and attacks, going underground again before Gravion can retaliate. Luna takes the G-Driller underground to drive it out. Gravion fires Graviton Missiles at close range with no effect. Luna attempts the Graviton Tornado Punch, a move they have never performed before, and succeeds in destroying the Zeravire. The team returns to relaxing on the beach when Sandman arrives, leaving them stunned.
