Sorry to keep you waiting! I'm Lum.
Lum misunderstood Ataru Moroboshi's proposal and has forced her way into his life as his "loving wife".
Lum met Ataru when he was randomly selected by a computer to face her in a game of tag with the fate of the earth on the line. Ataru had been promised marriage by Shinobu if he could win, so upon catching Lum he declared "Now I can get married!" Lum mistook this as a proposal to herself and accepted it. On her planet, engagements are sacred, she is completely determined to be married to Ataru for the rest of her life, falls completely in love with him, and refers to him as "Darling (ダーリン, Darling?)". She violently shocks him whenever he looks at or flirts with another girl (or if he insults her or does something to make her unhappy), but almost always forgives him in the end.
Urusei Yatsura: Only You
Lum appears in this film of Urusei Yatsura: Only You and attends Tomobiki High School, flying over Ataru. When she sits in the classroom for her lesson. Lum saves Ataru in inside the Clock Tower of school and hugs him.
Lum is a very sweet, innocent, faithful, and good-natured girl, but she can also be jealous and get very hot-tempered, usually due to Ataru and his incessant addiction of flirting.
Her ears are slightly pointy and she has long green hair. She has two tiny horns on her temples. She also has fangs on the top of her mouth.
She wears a tiger-striped bikini (based on the tiger-striped loincloths of mythical oni, which were made out of man's bad karma). Her bra is also used to hold some of her special devices.
When she began attending school, she wore a sailor suit and tried to act like a typical earth girl.
Powers and other Abilities
- Flight - Lum can fly to various heights into the sky, according to her own free will.
- Electric Shock - Lum can generate massive electrical discharges, usually from her hands.
- Creates Various Devices - Lum usually creates various devices that almost always lead to turmoil, if not chaos, whenever used.
- Storing Energy - Lum can store excess amounts of electricity in her body to supercharge her Electric shock, sometimes turning her body blue or gold in the process.
- Moroboshi Ataru - In the beginning of the story, Lum is constantly hugging and kissing Ataru (whether he wants it or not), but by the end she has calmed down considerably and simply holds onto his arm whenever they are walking somewhere. She is usually together with Ataru and does almost everything with him, be it eating lunch, going to and from school, or going to a festival. Because of this, she has come to consider and treat his room as her home, though Ataru insists she sleep sin the closet. Takahashi's reason for this is that two high school students shouldn't be sleeping together. They also share a kiss in the last episode of the series "All-Star Banquet! We Are Immortal!"
- Miyake Shinobu - She initially saw Shinobu as a rival that challenged her love for Ataru. However, as the story dragged on, they eventually become close friends and allies, using Shinobu's strength and Lum's electrical powers to accomplish things together. Shinobu gradually concedes and moves onto trying to build a relationship with Mendou, and then Inaba later in the series. She also sees Shinobu as her rival for Mendou and the Stormtrooper's affections, even though Shinobu has no interest in the Storm Troopers.
- Mendou Shuutarou - Lum has always viewed Mendou as a reliable and close friend. Although Mendou strictly loves just Lum, to where she is all that his eyes can perceive, Lum is only interested in Ataru. Mendou is very defensive and protective of Lum and is always looking out to assist her whenever needed, whether with his troops or with his own life. He treats Lum in a formal fashion and usually treats her to invitations and events.
- Benten - Lum and Benten are childhood friends that have always caused trouble and havoc. They help each other whenever it is needed.
- Oyuki - Lum and Oyuki are also childhood friends, but Oyuki in contrast to Lum has always held back and usually exhibited good behavior, although she has participated in the troublesome activities that Lum has participated in. Oyuki comes to Lum's assistance whenever she needs it, usually through the classroom's closet, freezing everything in her path.
- Ran - Lum and Ran are childhood friends, but they share a great rivalry that is largely based in vengeance. Lum respects Ran and is fearful of her tantrums, often "forgetting" events in the past where she got Ran in trouble. As a child, Ran looked up to Lum as a protector, but she felt victimized by all the numerous times that Lum has gotten her in trouble, such as blaming bed wetting on her, or almost allowing her to get eaten by a dinosaur. She also despises Lum for having stolen Rei's love in the past, and feels threatened that Lum may be trying to steal Rei again. Ran followed Lum to Earth to plot her revenge. Initially, her plan was to take Ataru away from Lum, and potentially poison him with her lips. At other times, she plots to poison her herself. Despite all the hostile ambitions, Ran views Lum as a friend that is always there for her, such as during the time when she was sick and Lum stayed by her bedside all night long.
- Ruu - He is Lum's and Ataru's descendant in this movie. Ruu and Lum meet each other.
Lum refers to herself in the first person as "uchi (うち, uchi?)" and is famous for usually ending her sentences with "~datcha (～だっちゃ, ~datcha?)". When used by itself, "datcha" means "Yes". A similar speech pattern appears in Takahashi's debut work Katte na Yatsura, where the dappyamen add "dappya (だっぴゃ, dappya?)" at the end of all of their sentences.

- Originally, Lum was not supposed to be a main character. She was meant to be a one time character and Shinobu was to take her place as the main love interest. However, fans loved Lum so much, that Lum became a main character; which is why Lum was absent for some parts of the first chapter of Urusei Yatsura.
- Her voice actress would voice a character from another work of Rumiko Takahashi : the mother of Kyoukai no Rinne's protagonist Sakura Mamiya. In fact, her color scheme may be a strong reference to Lum, and she is physically similar to Fumi Hirano.
- Another character from Kyoukai no Rinne, Renge Shima has two oni horns just like Lum.
- Lum makes a cameo in episode 4 of Kyoukai no Rinne as one of the dolls in the claw machine, along with Ranma, Akane, P-chan, and Genma's panda form from Ranma 1/2. However, Lum has purple hair instead of her iconic green.
