Simon

Simon lives underground in a village where people have spent generations sheltering from earthquakes and cave-ins. He is shy and naïve, unlike his friend Kamina, who insists that a surface world exists above them. While digging, Simon uncovers a small mecha called Lagann. When the village ceiling breaks open and a Gunmen falls through, that discovery gives him and Kamina a way to fight back and reach the surface.

That beginning makes Simon’s contrast with Kamina more than a personality gag. Kamina supplies the bold declaration; Simon discovers the thing that lets them act on it. His technical curiosity is his first form of courage, and it gives Gurren Lagann a grounded entry into its huge, escalating adventure.
