Kamina allows Simon to join his gang, Team Gurren, to help him achieve his dream of visiting the surface world. One day, Simon unearths a drill-shaped key called a Core Drill, followed by a small mecha resembling a face called a Gunmen.910 Shortly thereafter, a giant Gunmen crashes through the ceiling and begins attacking the village, followed by a girl named Yoko who attempts to repel the Gunmen.

Simon and Kamina learn from Yoko that humans on the surface are attacked each day by Gunmen piloted by beastmen, humanoid creatures who serve as Lordgenome’s army.
