So if G. Dustox really is a thing, and not just a fashionable change to fit Klara's style, I think it works like this. Klara's whole deal is that she is a Poison Type expert who LOOKS and acts nice and sweet and cute. But that's clearly all a ruse. Her speaking style indicates that she's not genuine and her name is Japanese can be read "yabai" which literally means "dangerous".
You attract more flies with honey than with vinegar. It's better to be sweet than to be acidic, if you're trying to get something out of someone. She's playing off this idea of being a hidden killer underneath a veil of innocence.-
I think nuDustox is Poison/Fairy. It PRETENDS to be a butterfly, but is not one. Playing off the idea that butterflies and moths are often confused with each other. It's trying to disguise itself as something harmless.
