Ep. 12: Eiji and Leele split forces to defeat three Zeravire and restore communication
Gravion struggles against the Zeravire due to a jamming signal blocking the Gran Knights' summoning. Yumi wakes up and urges Eiji to pilot the robot while Cookie rescues her. Sandman identifies a third Zeravire in the atmosphere as the signal source and orders its destruction. After being overwhelmed and falling back to Earth, Eiji and Leele reunite with the disassembled Gravion. Ignoring Sandman's caution, they split their forces to attack all three enemies simultaneously. The G-Driller destroys the first Zeravire, which reforms, while Leele, Mizuki, and Eiji defeat the airborne one. Its final laser broadcast ends the jamming signal, allowing Gravion to breach the ground Zeravire's barrier and destroy it. After eliminating the last enemy, Eiji visits the recovered Yumi and returns to the castle to rejoin the fight.
