Yuki, whose last name is unknown and is of Japanese descent, is one of Mertle's best friends and Lilo's rivals. She usually travels in a group with her leader Mertle and the other two girls, and seldom say anything other than a sarcastic "Yeah!" in unison with her friends when agreeing with whatever mean thing Mertle has just said about Lilo. It is often hinted that she and the other two girls would probably actually like Lilo if Mertle didn't make them think that they didn't. She and the others have even ditched Mertle to hang out with Lilo for a while, like in the episodes "Tank" and "Shush", and they seemed to have enjoyed their time with Lilo on both occasions up until going right back to Mertle in the end.
Not much is known about her personality because her character was not focused on a whole lot. She obviously enjoys the art of hula dancing, since she attends a hula class along with her friends. While she is mostly mean towards Lilo and Stitch, she is also kind to them as well, usually when Mertle is not around at all, so it's hard to tell whether she is a nice or mean person.
Also, from what as been seen and heard in couple of episode, she appears to have an interest in hockey because in the episode "Cannonball", she drew a doodle of a hockey player, and in the episode "Yaarp", she says, "I still think we need a hockey rink." Additionally, in the episode "Spooky", after Mertle states they shouldn't all be princesses, and that one of them would have to change their costume, Yuki says, "But this was your idea; I wanted to be a hockey player."
If she isn't dressed in her hula dance outfit when performing or practicing hula dancing, then she can be seen wearing a pair of dark green flip-flop sandals, along with a pair of dark green shorts and a short, light green short-sleeved shirt, which exposes her bellybutton. She also has short, straight brown hair with two small light green hair clips in them.
Family and Relatives
At the the very end of the episode "Wishy-Washy", there is picture of her with her parents just to show what they look like, but this is about all that is known about them. Also in the episode "Finder", she apparently has an uncle as well, when she remarks, "I wonder if he could find my uncle Jimbo."
- In the intro sequence of the series, Yuki appears in two squares in the hula dance, her image and movements mirrored to one another.
