Dokonjou Gaeru

Dokonjo Gaeru/Gutsy Frog was already one of Imaishi's biggest influences even before this show came announced (see the art in his Abenobashi episodes); however, those influences were more visual than anything else. Kill la Kill takes the inspiration to the next level by featuring a living, talking, moving piece of clothing that uses its sleeves as limbs and can overpower its wearer. 

Both involve magical wise-cracking creatures who go on silly adventures and wacky hijinks with young boys.
