She is Lum's best childhood friend from elementary school, but when they got older they both fell in love with the handsome shape-changer Rei. Rei chose Lum, but she eventually realized he was a shallow glutton and dumped him and soon after got engaged to Ataru Moroboshi. Because of all of this, Ran has come to Earth in order to exact revenge on Lum.
She follows Lum to Earth and enrolls in Tomobiki High School, but has a different class than Ataru and the main cast. She plans to exact on Lum by kissing Ataru and stealing his youth. As the series progresses, she begins to date her beloved Rei. Although Rei seems to be mainly interested in the food she cooks for him, Ran is happy with whatever she can get.
Ran tends to act very cutely in public. She shows an sweet, child-like if not even elegant side when she is happy but when she becomes suspicious or even angry her personality turns into complete opposite. When she was a child she was usually violently punished by her mother which could have traumatized Ran to develop her split personalities. She shows her anger and suspiciousness towards Lum, who she believes wants Rei back.
Ran is desperately in love with Rei and is jealous of Lum, as Rei is in love with her.
At first glance, Ran seems to be a sweet and lovely redhead, but in reality this is all merely an act. While she usually behaves as an elegant maiden, when she gets angry her fangs and violent nature are exposed and she begins speaking in Kawachi dialect.
She apparently did not develop her sweet persona until sometime after she fell out with Lum, as Lum is shocked to encounter it when Ran first arrives on Earth. (It seems likely that she took it up in the hopes of wooing Rei back.) When Lum asks her why she does not simply act naturally, she replies that if she were to break character even once it would destroy the credibility of her newly adopted personality. Hilariously, Ran is wrong—boys are so captivated by it that they never seem fazed at all no matter how many times they witness her harsher side resurfacing.
She is usually seen wearing a skimpy silver bikini (pink bikini in the manga and in Urusei Yatsura 3: Remember My Love) or a light-colored dress and chiffon (the latter more than the former). While attending Tomobiki High School, she wears the standard girl's uniform.

Ran spent most of her childhood as Lum's friend which led her to numerous problems which her mother would punish her later. Lum and Ran even shared the same love interest, Rei, but Lum left him. When meeting again, Ran and Lum were first happy to see each other but then Ran remembered that she wanted to exact vengeance for her traumatic childhood and broken heart on Lum. They still do act like friends, though Lum becomes more and more careful with her and Ran is suspicious on Lum because of believing that she is still in love with Rei.
Ran usually takes advantages over Atarus flirtatious personality. In couple of her first appearance Ataru was her weapon for revenge towards Lum as she tried to suck his youth, eventually not failing each time (Though she unofficially succeed one time but Ataru had drank Youth Restoration Potion made by Cherry, making it look that she failed). Apart from Lum, Ran is only one to call Ataru "Darling".
Ran is desperately in love for Rei, who chooses Lum over her. Ran and Rei start dating at one point and Ran prepares a lot of food for him each time, though food is probably the reason why Rei dates her since Rei still tries to find possible ways to get Lum back. Ran does anything to keep love between Rei and Lum from triggering again.
