I Don't Get It, Not One Bit!

Riding conditions spark the opening squabble: Yoko crowds into Gurren beside Kamina because sitting on the team's bare metal transport block leaves her sore. Kamina fires off one crack too many about her backside, she answers with live rounds, and in the chaos he tramples the exact patch of terrain Leeron has just flagged as unstable. The whole brigade drops straight into the earth.

They come to inside an underground settlement whose residents mistake them for angels, since anyone descending in a Gunman must be divine; the villagers hold Gunmen to be face gods. Their first acquaintances are Rossiu, the village leader's son, and a pair of orphans named Gimmy and Darry. Father Magin, the head priest, arrives to receive the visitors, and he and Kamina despise each other on sight.

Generous hospitality hides a brutal custom. The settlement caps its population at fifty, and once the count is exceeded, lots decide which two residents ascend to "heaven," in truth banishment to the surface. The draw condemns Gimmy and Darry. Kamina explodes at the priesthood, insisting the world above is closer to hell than paradise for small children, and nearly comes to blows with an angered Rossiu. The standoff breaks when a hostile Gunman crashes into the cavern. Kamina and Simon merge their machines into Gurren-Lagann to meet it, but the village's own idol rises and joins the battle, flinging the intruder down an enormous waterfall. Its pilot turns out to be Magin himself, who quietly asks the outsiders to move on. The orphans' exile still stands, Rossiu elects to accompany them, and Team Gurren brings all three aboard as the journey toward the return point continues.

Rossiu makes his first appearance, alongside the debuts of Gimmy and Darry; all three leave the underground village and join Team Gurren. The episode also reveals that the settlement's worshipped god Gunman is a working machine with Father Magin at the controls, and it marks another successful Gurren-Lagann combination in battle.

The episode premiered in Japan on April 29, 2007, with the English broadcast following on August 11, 2008. It sits between Episode 4 and Episode 6 in the series order, and its title comes from a line of Kamina's, following the first part's naming convention.
