Gurren Lagann, known in Japan as Tengen Toppa Gurren Lagann (天元突破グレンラガン, Tengen Toppa Guren Ragan, lit. "Pierce the Heavens, Gurren Lagann"), is a Japanese mecha anime television series animated by Gainax and co-produced by Aniplex and Konami. It ran for 27 episodes on Japan's TV Tokyo between April 1, 2007, and September 30, 2007. It was directed by Hiroyuki Imaishi, written by veteran playwright Kazuki Nakashima, both of whom would later collaborate on two more projects, Kill la Kill in 2013 and Promare in 2019, and had been in development since the participation of the famed animator in the Abenobashi mecha-themed episodes by the same studio. Gurren Lagann takes place in a fictional future where Earth is ruled by the Spiral King, Lordgenome, who forces mankind to live in isolated subterranean villages. The plot focuses on two teenagers, Simon and Kamina, who live in a subterranean village and wish to go to the surface. Using a mecha known as Lagann, Simon and Kamina reach the surface and start fighting alongside other humans against Lordgenome's forces, before fighting the forces of their true enemy.
