Two friends, Simon and Kamina, become the symbols of rebellion against the powerful Spiral King, who forced mankind into subterranean villages.

Simon: Even if we were to be enslaved by the galaxy's cycle of rebirth...
Yoko: ...The feelings that were left behind will open the door!
Leeron: Even if the Infinite Universe was to go against us...
Viral: ...Our burning blood will cut through fate!
Dai-Gurren-Dan: We'll break through heaven and dimensions! We'll show you our path through force! TENGEN TOPPA GURREN-LAGANN! JUST WHO THE HELL DO YOU THINK WE ARE?
[repeated line]
Kamina: Who in the hell do you think I am?
