Rap is the language of a man's soul

A naked Gimmy treks across open terrain until he stumbles onto a goofy, bottomless version of Simon waving at him. Gimmy strikes with a kancho, the Japanese schoolyard prank of sneaking up on a victim and jabbing at their backside. The blow sends Simon rocketing free of his signature jacket, and Gimmy takes it before moving on. Kamina suffers the same treatment and loses both his cape and his sunglasses.

Yoko proves a harder target. She senses Gimmy creeping up behind her and freezes him with a menacing glare, but the boy feints a retreat, distracts her, and makes off with her bikini top anyway. Simon, Kamina, and Yoko give chase in Gurren Lagann, only for Gimmy's prank to bring down the mecha itself. A final cut to Gimmy asleep in the nude reveals the whole rampage as his dream.

Gimmy's kancho attacks claim Simon's jacket, then Kamina's cape and sunglasses, and finally Yoko's top. The pursuit in Gurren Lagann ends with the mecha destroyed by the very same prank, and the closing shot reframes everything as a sleeping boy's fantasy.

This short marks one of only two occasions in the franchise where Yoko's nipples are shown. Its premise recalls Episode 6's director's cut, in which Gimmy misreads Simon's instruction to find a hole and Kamina eggs him on while hoping to spy on the women bathing on the far side of the spring. A few shots from that episode resurface in the video.
