Yuki, being a skunk of course, has a certain ordor, though unlike a regular skunk it comes from the follicles of her tail rather than...you know...the usual place. It's best not to breathe it too deeply or you might find yourself....rather suggestible.
combatraccoon did this for me a night or two ago! The original idea was that Yuki's tail would literally turn into smoke Sombra style, but with light miscommunication it turned out the more traditional way. Still I quite like it!
