The name is a reference to the urban legend of the "Daruma Woman". Simply put, it says a woman was kidnapped overseas and years later was found alive with her arms, legs, and tongue cut off in a shop in a foreign country that had "Daruma" in Japanese on its sign. As Lancis said to Misaka Mikoto, "…I’m not sure what you’re expecting, but we can even get you things like human skulls."
