     Main Characters 

Ataru Moroboshi

Miss! What's your address and phone number?

Voiced by: Toshio Furukawa (JP), Steve Rassin (EN, Movies 1, 3-6), Michael Sinterniklaas (EN), Vinnie Penna (EN, Movie 2)

The main protagonist of the series. A lazy student at Tomobiki High School, Class 2-4, Ataru suffers from an incredible amount of bad luck, having been born on Friday the Thirteenth, during a major earthquake, and Butsumetsu, the unluckiest day of the Buddhist calendar. Thanks to this lack of good fortune, his triumph in the game of tag that saved Earth from Oni invasion turned into a defeat for him. His victory statement, intended to confirm his then-girlfriend Shinobu's promise to marry him if he won, was misinterpreted by Lum to be a marriage proposal. Much to his chagrin, she accepted.

Lum Invader

Darling no BAKA!!

Voiced by: Fumi Hirano (JP), Shannon Settlemyre (EN, Movies 1,3-6), Martha Ellen Senseney (EN), Roxanne Beck (EN, Movie 2), Larissa Murray ("Lum the Invader Girl" dub)

The female protagonist of the series. She is a beautiful Oni alien who is capable of flying and generating electrical shocks and even lightning. She falls in love with Ataru after his "marriage proposal". While generally good-natured, sweet, faithful, and innocent, Lum is very jealous and has a very hot temper.

Shuutarou Mendou

"Waaaah! It's dark! It's cramped! I'm scared!!!"

Voiced by: Akira Kamiya (JP), Robert Rogan (EN, Movie 1,3-6), Vinnie Penna (EN, Movie 2), Brian Hudson (EN, TV)

Heir to the Mendou Conglomerate with staggering wealth and its own private army. He commutes to school in a gigantic helicopter that is more like a flying mansion. A descendant of a samurai family, Shutaro often carries a katana with him, which at any moment could be flying at Ataru's face, who has become adept at blocking it with his bare hands. Although very handsome and intelligent, he is truly just as foolish and lecherous as Ataru, just much more sophisticated in his approach.

Shinobu Miyake


Voiced by: Saeko Shimazu (JP), Danielle Sullivan (EN, Movie 1,3-6), Katherine Burten (EN)

Ataru's childhood friend and classmate. Until Lum showed up she was also Ataru’s girlfriend. She claimed that if Ataru won the tag game, she would marry him, which while encouraging enough Ataru to win, became his victory cry that led to Lum deciding to marry him. She is a neat, sweet, petite young lady. Despite these feminine characteristics, Shinobu often displays super-human strength, with her being one of the strongest characters in the story, able to easily throw the desks of the classroom and almost any other large/heavy object/structure at hand as needed.

     Tomobiki High School 


Voiced by: Tomomichi Nishimura (JP), Jeremy Griffin (Movie 4), Draidyl Roberts (Movie 2)

The principal of Tomobiki High School. A soft-spoken, balding, nearsighted middle-aged man, he treats all of the weird goings-on at the school as harmless student shenanigans.


Voiced by: Michihiro Ikemizu (JP), Bradley Evans (EN, Movies 3-6), Sean Barret (EN, BBC dub), T. Roy Barnes (EN, Movie 2).

The English teacher of the Class 2-4, "Classroom of Failure". Originally contracted by the Principal of Tomobiki via the "Trump-Card Teachers" Organization. A sad, middle-aged man, whose only interest is to teach at Tomobiki High, but he fails due to the constant interruptions during class, when the classroom itself is not destroyed by Lum, Ten or Shinobu.

Ryuunosuke Fujinami

Voiced by: Mayumi Tanaka (JP), Morgan Jarrett (EN)

A classmate of Ataru. She is a girl, but her eccentric father has raised her as a boy. Her greatest desire is to behave appropriately for her gender.

Kousuke Shirai

Voiced by: Kappei Yamaguchi

Ataru's classmate and best friend.

The Lum Stormtroopers: Megane, Perm, Chibi and Kakugari

Megane is voiced by: Shigeru Chiba (JP), Marc Garber (EN), Colin Hackman, Craig Wollman (EN, Movies)
Perm is voiced by: Akira Murayama (JP), Adrian Monte (EN), Jonathon Guggenheim
Chibi is voiced by: Issei Futamata (JP), Steven Paul (EN)
Kakugari is voiced by: Shinji Nomura (JP), Langley McArol (EN)

Four schoolboys from the same class as Ataru who are in love with Lum and have sworn to protect her from Ataru.
  • Ascended Extra: In the anime.
  • Ax-Crazy: Megane in some episodes.
  • Composite Character: In the anime, Perm and Megane take most of the roles Kousuke had in the manga. It helps that Perm actually looks similar to Kousuke.
  • Only Known by Their Nicknames: The names they are known with refers to some physical characteristic of them, and means glasses (Megane), permanent (Perm?), tiny (Chibi) and crew cut (Kakugari). That said, Megane's, Chibi's and Kakugari's real names are actually known (Satoshi, Akira and Hiroyuki respectively), with only Perm's being unknown.
  • Those Four Guys



Voiced by: Yuuko Mita (JP), Satu Rautaharju & Natasha Malinsky (EN, Movies).

An alien girl of Gods of Luck clan and Lum's childhood friend.


Voiced by: Noriko Ohara (JP), Jaime Phelps (EN, Movies)

Lum's other childhood friend and the Queen of Neptune, which in the series is a frozen, snowy planet populated entirely by women, as most of the men have to go off-planet to find work.


Voiced by: You Inoue (JP), Kazue Komiya (JP, later OVA's), Morgan Jarrett (EN)

Lum's "best" childhood friend. She appears to be a sweet and lovely redhead, but in actuality has a violent, evil side. Her special power is the ability to suck the vitality out of a person’s mouth while kissing them. She can also use this power in reverse. As a child, Ran was often hurt or got into trouble because of the antics of the more carefree and irresponsible Lum. Also, she is in love with Rei who unfortunately still loves Lum. This are the reasons why she hates Lum and wants to revenge against her.


Voiced by: Tessho Genda (JP), Jeremy Griffin (EN)

Lum's ex-fiance. A very handsome oni, to the point of wooing almost any girl just by them seeing his face. While he is constantly interested in eating, he has a muscular yet slim build, which furthers his good looks. Rei has not yet learned to speak Japanese fully, so he can only speak 1-5 words at a time in Japanese. Lum broke up with him because of his low, simple intelligence and obsession with food. However he followed her to Earth to regain her love. He has the ability to transform into an "ushitora", a huge creature resembling a cross between a tiger and a bull.

Princess Kurama

Voiced by: Rihoko Yoshida (JP), Daisy Talley (Dub for public TV and movie 1 dub), Stacey Jefferson (Dub for BBC 3)

The "crow princess". A humanoid female from an alien race of crow tengu, she is destined to mate with the man that awakens her from her slumber with a kiss. Unfortunately for her, that person turns out to be Ataru. Although she has no real desire to sleep with him, for the sake of her race, (And initially because when Lum first dragged Ataru away from their initial meeting, Kurama responded "What is it about other peoples things that makes me want them"), she goes to great lengths in an attempt to turn the perverted letch into a man worthy of fathering her children while fighting off both Lum and Shinobu. She has the ability to create powerful gusts of wind with her multi-use giant leaf.

Jariten (a.k.a Ten)

Voiced by: Kazuko Sugiyama (JP) Shannon Settlemyre (EN, Movies 1,3-6), Mindi L. Lyons (EN), Paula Parker (EN, Movie 2)

Lum's infant cousin. He has a single horn on his head and can breathe fire.
  • Bratty Half-Pint: He loves to act high and mighty, and puts on a façade of innocence ("I'm a good boy" is pretty much his Catch Phrase), but in reality he mixes a considerable amount of mischievousness with the same lecherous attitudes as Ataru and Mendo. He loves to stir up trouble to keep himself amused, playfully flirts with every girl he sees, and because he's considered an adorable infant, he can usually rely on women to protect him when he gets into more trouble than his ability to fly and breathe fire can handle. And even when they turn against him, Lum always supports him, to the extent she pays it no mind at all when, say, Ten shows up at Ataru's school and starts randomly biting people to soothe his toothache.
  • Catch Phrase: "I'm a good boy!"
  • Chew Toy
  • Deliberately Cute Child
  • Disappeared Dad: Ten's dad was never mentioned.
  • Jerkass/Jerk with a Heart of Gold
  • Kansai Regional Accent: He occasionally displays features of Kansai-ben.
  • KidAnova
  • Meaningful Name: Jari sort of means "brat". So calling him by his full name Jariten is the same thing as calling him "bratty Ten".
  • Playing with Fire
  • Precocious Crush: On Sakura.
  • Spoiled Brat
  • Wise Beyond His Years

Lum's parents (Mr and Mrs. Invader)

Lum's father is voiced by: Ritsuo Sawa (JP), David Krause (EN), Anthony Lawson (EN, Movies)
Lum's mother is voiced by: Reiko Yamada (JP), Kristen Foster (EN)

Lum's father is a huge, pudgy oni, and tends to be loud and scary. However, he is just as afraid of his wife as Ataru is of Lum. Lum's mother is a pretty woman who can only speak in the oni language.

Ten's mother

Voiced by: Keiko Yokozawa

A firefighter who takes great pride in her work. When Ten was living with her, she would tell him stories of her work in the field, expressing her contempt for arsonists and pyromaniacs, who she feels should be sent straight to Hell. She is very busy and would leave him with a robotic nanny, which has contributed to his precociousness. Since her son breathes fire and uses his power liberally, he lives in terror of what will happen should she ever find out. She loves Ten very much, despite the rareness of her being able to visit him.
  • Catch Phrase: "FIRE!!"
  • Hot Mom: Being old enough to be a mother has done nothing to detract from her looks.
  • In Harm's Way: It's implied that she feels the most comfortable when fighting fires—the bigger, the better.
  • Parents as People: While she usually left Ten int he care of a robotic nanny, she regrets not being able to spend more time with her son.
  • Unnamed Parent
  • Workaholic: She constantly carries around her firefighting equipment.

The Spice girls: Sugar, Ginger and Pepper

Voiced by: Tarako (Sugar), Chika Sakamoto (Ginger), Rumiko Ukai (Pepper)

A trio of teenage girls who currently attend the same junior high school that Lum, Benten, and Oyuki did. Due to their seniors' reputation for causing mischief, the Gang of Three seeks to outdo their predecessors by defeating them in combat, but most of the time, they resort to simple pranks and underhanded schemes.

Ran's mother

Voiced by: Yukiko Nashiwa

An extremely strict parent. She always blamed Ran for many misdeeds that Lum committed as a young girl and constantly punished her with a severe spanking.


The antagonist from the first movie, Only You. She is the lovely ruler of planet Elle. When Ataru was a child, he played a game of shadow tag with Elle and it is a custom on her planet that stepping on someone's shadow counts as a marriage proposal. Now she has came to claim her husband.


Voiced by: Kaneto Shiozawa

The prince of a world of total darkness, giant mushrooms, and flying pigs. It was arranged by his great-grandfather that he would marry Lum.


Voiced by: You Inoue

Rupa's childhood friend. Ever since they've been children, Carla has loved Rupa. When one day Rupa showed Carla a picture of Lum, his bride-to-be, Carla changed from a childhood friend to a violent assailant.

     Other Characters 

Ataru's parents

Ataru's father is voiced by: Kenichi Ogata (JP), Marc Matney (Dub for public TV), Alan Marsh (Dub for BBC3), Jerry Winsett (EN, Movies 1 and 3-6 dubs), Larry Robinson (Movie 2 dub)
Ataru's mother is voiced by: Natsumi Sakuma (JP), Dorothy Rankin (Dub for public TV), Stacey Jefferson (Dub for BBC3), Belinda Keller (EN, Movies 1 and 3-6 dubs), Jackie Tantillo (EN, Movie 2 dub)

Ataru's father is a typical salaryman. Wearing a yukata around the house, he desires a nice and quiet homelife. In the anime his home is frequently destroyed, causing him to lament over the mortgage. Ataru's mother is a typical housewife, who is extremely ashamed of her son.
  • Catch Phrase: Ataru's mother usually says "We never should have had him!"
  • Housewife: Ataru's mother.
  • No Accounting for Taste
  • Parental Neglect: Mostly because of Ataru's mother; in the first manga story, Ataru's mother said "Ataru, you be sure to come home for the holidays!" and she always laments "I wish I never had him" throughout the manga and anime (sometimes in hearing range of Ataru). Atop that, there's the "omiai" scene in the movie Only You, where Ataru's parents force join with Lum's parents to force him to marry her officially...all so that Ataru's parents will get better lives for themselves on the Oni homeworld.
  • Salaryman: Ataru's dad works long hours and worrying about the mortgage, especially since his house is routinely destroyed.
  • Unnamed Parents
  • Why Couldn't You Be Different?: Ataru's mother is constantly going "I wish I never had him." There's also a scene where both parents are away reminiscing about their life, and when they start talking about Ataru, both say that they had wanted a girl at the time.
  • Your Cheating Heart: Ataru's mother has a crush on Rei, to her husband's despair.

Sakuranbou aka Cherry

Voiced by: Ichirō Nagai (JP), Eric Paisley (EN)

A wandering monk. Cherry has amazing spiritual powers (or so he claims) and he often predicts doom for Ataru.


Voiced by: Machiko Washio (JP), Karen McIntyre (EN)

Cherry's niece. She was once a very sickly girl who suffered from a variety of ailments. Many of them were the result of spirits that infested her body. After meeting Ataru the first time, she tried to exorcise him, during which process, the demons who inhabited her transferred themselves to the unlucky young man, rendering her perfectly healthy. Soon afterward, she took a job as the Tomobiki High school nurse, where she again encountered Ataru and half accidentally exorcised the disease spirit still haunting him from that encounter. Like her uncle she loves eating and sometimes gets into a fight with him over it.

Tsubame Ozuno

Voiced by: Kazuhiko Inoue (JP), Sean P. O'Connell (dub for public TV), Eric Meyers (dub for BBC 3)

Sakura's fiance. Tsubame is mellow and somewhat weak-willed in comparison to the strong and powerful Sakura. He is also a magician, trained in Western magic but with very little success.


Voiced by: Tomohiro Nishimura

A giant ghost cat that goes to great lengths to sit under a kotatsu because it hates being cold. He originally was a kitten who was abandoned centuries ago and froze to death, so the spirit does little else but seek out warmth. He often can be seen as a companion for either Cherry or the Tomobiki High Principal, usually enjoying tea with them. He also occasionally acts as a companion to Ten which could be in part due to Ten's ability to breathe fire.

Ryouko Mendou

Voiced by: Mami Koyama (JP), Michele Seidman (Dub produced for public TV and movie 3 dub), Toni Barry (Dub for BBC 3)

Shuutarou's younger sister. Ryoko is a spoiled girl whose only amusement seems to be the creation and execution of elaborate plans intended to drive her older brother mad.

Shuutarou and Ryouko's parents

Mendou's father is voiced by: Mugihito (JP)
Mendou's mother is voiced by: Akiko Tsuboi (JP)

The very proud and dignified heads of the Mendou conglomerate. The father is a bit of a flake and a jokester which he often hides behind an air of seriousness. The mother is old fashioned and refuses to use modern conveniences.

Tobimaro Mizunokuji

Voiced by: Bin Shimada (JP), Scott Whiteside (Dub for public TV and movie 4 dub), David Jarvis (Dub for BBC 3)

The son of the second richest family in Japan and Mendou's rival. Although he and Mendou were childhood friends, they had a falling out concerning a long-standing baseball rivalry, even though neither is any good at baseball—Ton can't pitch and Mendou cannot swing, and so Ton returns to settle the score.

Asuka Mizunokuji

Voiced by: Sumi Shimamoto

Tobimaro's sister. The very beautiful and petite girl was isolated, according to the Mizonokuji family's tradition, from any and all males from the moment of her birth until the age of 16, at which time an omiai will be held for her to get married. As such, even her brother was unaware of her existence until then. Thanks to her daily training and the genetics she inherited from her mother, she is insanely strong. Nevertheless she is extremely timid and deathly afraid of males, in part because the first one she ever met was Ataru Moroboshi.
  • Arranged Marriage: With Mendou.
    • Perfectly Arranged Marriage: After seeing how she really looks like under her armor, Mendou becomes very motivated to marry Asuka. Asuka, on the other hand, comes to accept him after she finds out he's a "big brother" like Tobimaro.
  • Beautiful All Along: Asuka doesn't look very attractive at first, because of the armor she wears. After Lum accidentally destroys the armor, we see how beautiful she actually is.
  • Big Brother Attraction: Subversion: the extremely sheltered Asuka fears all men except her "big brother" ("a special kind of man who is just like you!"). She considers Mendou (her fiance due to a family agreement) her brother because she heard Ryoko refer to him as such once and Ryuunosuke, since she was wearing her sarashi that matched her actual brother Tobimaro's. Guess which "brother" has to endure rib-crushing hugs in his bed or bath? Hint: he's rather terrified of this and their mother blames it on him.
  • Break the Cutie: Parodied. She would likely be the one to break anyone in half. Now, if only her nemesis wasn't Ataru...
  • Catch Phrase: "EEEEK! A man!!"
  • Charles Atlas Superpower
  • Does Not Like Men
  • Exotic Eye Designs: Her eyes have star-shaped pupils like her brother.
  • Extraordinarily Empowered Girl
  • Fragile Flower
  • The Ingenue
  • No Social Skills
  • Shrinking Violet
  • 24-Hour Armor: Asuka likes to wear a tank-like armor because it makes her feel safe.

Tobimaro and Asuka's parents

Tobimaro's mother is voiced by: Yukiko Nashiwa
Tobimaro's father is voiced by: Issei Futamata

Heads of the Mizunokuji sporting goods empire. The mother's problem lies with her children's warped relationship. She is even more powerful than Asuka. She can even do the "angry big-head" technique.

Ryuunosuke's father

Voiced by: Masahiro Anzai (JP), Langley McArol (EN)

A very creepy individual. His family ran a small seaside teashop for generations, and he seeks an heir to continue the business after he dies. However, he believes that only a man can run it and his late wife Masako left him only a daughter, Ryuunosuke. Not one to let that get in his way, he proceeded to raise her as a boy and succeeded in making her a man among men, if only she were a man. Mr. Fujinami refused to let Ryuunosuke get a bra, forcing her to wrap her bosom for support, which he claims will reduce the prominence of the sizable "tumors" on her chest. He also is inspired almost entirely by the sea. If he gets too motivated, he shouts "I LOVE THE SEA!!", which is accompanied by a massive tidal wave regardless of his location.


A young kitsune that develops a crush for Shinobu when he first meets her.


Voiced by: Kaneda Kimotsuki

A gang leader of Butsumetsu High School who has enormous lips. He is often seen chasing Shinobu.


Voiced by: Hirotaka Suzuoki (JP), Jonathan Soronen (Movie 5 dub), Edward Glen (Nub for BBC 3)

An employee at the Fate Production Bureau which makes doorknobs to the Dream Realm. A bumbling yet kind-hearted young man who wears a rabbit costume which allows him to travel freely to and from subspace. He ends up falling in love with Shinobu after she finds him passed out and hungry in the street and gives him some food.


Voiced by: Tōru Furuya

A young man who grew up all alone in the Mendou Family Electric Jungle and was raised by his "Grandfather" (a TV). He has built up a resistance to electricity and therefore cannot be affected by Lum's shocks. Shingo falls in love with Lum and kidnaps her, but when she is rescued by Ataru and the others Shingo falls in love with Shinobu. He later becomes Mendou's personal ninja bodyguard.

Nagisa Shiowatari

Voiced by: Mitsuki Yayoi

A guy who was raised as a girl. He is introduced as a ghost because he and his father died as a result of overeating sea urchin-flavored kakigori. Long ago he was engaged to Ryuunosuke through their parents, and fell in love with her upon meeting her. Later Nagisa gets a new flesh-and-blood body and moves in with Ryuunosuke.
