The Left-handed Lurning Wrench serves as the instrument of Agatha's introduction to Gilgamesh Wulfenbach aboard Castle Wulfenbach.[1] We don't know exactly what it does (as usual for Sparky tools), but Gil needs one to work on his flying machine. She brings it in the next scene, with no small element of frost in her demeanor, as she holds Gil responsible for the death of Tarsus Beetle, whom she idolized in her student days at Transylvania Polygnostic University.[2] Gil takes the opportunity, however, to clue her in on just what was going on in that laboratory -- and a relationship is born, such as it is.
