Main Characters

    Ataru Moroboshi

"Miss! What's your address and phone number?"

Voiced by: Toshio Furukawa (JP, original series), Hiroshi Kamiya (JP, All-Stars), Steve Rassin (EN, Movies 1, 3-6), Michael Sinterniklaas (EN, test dub), Wayne Grayson (EN, Movie 2), Matt Lucas (EN, BBC gag dub), Candice Moore (EN, Animax Dub)

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 of April during a major earthquake… which also happened to be 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 to her. Much to his chagrin, she accepted.

  • Abhorrent Admirer: To nearly all the supporting female characters and every pretty girl he sees. He literally throws himself at the girls he likes and always gets beaten up as a result.
  • Accidental Proposal: In the first chapter/episode, after he catches Lum in the game of tag, he yells "Now I can get married (to Shinobu)!". Lum misinterprets his statement as a marriage proposal for her and she considers him her fiancé from then on.
  • Affectionate Nickname: Lum calls him "Darling".
  • Anti-Hero: He's a good guy deep down, but is often a selfish, lazy, and lecherous Loser Protagonist. Overall, he's mostly a Classical Anti-Hero.
  • Aw, Look! They Really Do Love Each Other: He has his moments with Lum. While he would never admit it, he cares for her deep down and is ready to rescue her when she is in danger.
  • Barehanded Blade Block: Ataru is a master of this, usually against Mendou. In fact, he provides the trope image!
  • Beady-Eyed Loser: The unluckiest and most perverted man in the universe. And also the most beady-eyed.
  • Be Careful What You Wish For: When Ataru sees his dream reality, he learns that in exchange of him getting a harem, Lum leaves him because he extorted and neglected her. He then realizes a harem isn't worth it if Lum isn't with him.
  • Belated Love Epiphany: He has one every time Lum apparently leaves him and he starts missing her badly. He returns to denial once she comes back, though.
  • Belligerent Sexual Tension: With Lum. While their feelings are mutual, he's too much of a lecher and she's too possessive. Since they're both very stubborn, neither of them wants to ever change and they keep arguing forever.
  • Big Eater: When he's not chasing girls, his sole other interest is in food.
  • Blessed with Suck: His Accidental Marriage to a beautiful alien princess who genuinely loves him and sees his better qualities… and is a Tsundere Clingy Jealous Girl Lethal Chef who will electrocute him every time he chases another girl.
  • Book and Switch: He is shown hiding a girly mag inside one of his books.
  • Book Dumb: He’s often shown to be a slacker and an underachiever with his schoolwork, but can be quite crafty when it comes to his schemes.
  • Born Unlucky: His birthday is even April 13th† , and the litany of bad luck omens associated with him appeared before he was even born, such as being born during an earthquake. Not to mention his Meaningful Name (roughly translated, "hit on the head with a falling star").
  • Brilliant, but Lazy: While he's most definitely not dumb, he doesn't care about school and just wants to live for the day.
  • Butt-Monkey: This guy never catches a break. He gets better in later chapters where he actually becomes more clever and able to come out on top, especially in his petty rivalries with Mendou or Ten. Though he still gets a lot of punishment when he's being a Casanova Wannabe.
  • Cannot Spit It Out: Ataru can't admit he really loves Lum because, if he did, he'd have to give up his dreams of a harem. Though in the fifth movie when Lum threatens to erase the memory of herself from everyone on Earth, he won't say it because if he said it at that point it would be a Cassandra Truth.
  • Can't Act Perverted Toward a Love Interest: Played with. Lum is the only female in the universe he doesn't harass. Ironically, she is also the only female who'd be happy to get his attention. However, the reason behind this is, at least in the beginning, that he simply doesn't want Lum as a Love Interest – at first, he prefers Shinobu, and later he'd prefer any other woman but Lum. It takes some relationship development before he properly fits this trope.
  • Can't Live With Them, Can't Live Without Them: Ataru constantly chases all girls other than Lum. Yet whenever Lum disappears from his life, he'll instantly drop his perverted maneuvers and go to great lengths to get her back. That doesn't stop him from immediately resuming his lecherous ways the moment she's safely back.
  • Casanova Wannabe: He is always ready to ask a random girl off the street for her address and phone number. This despite having an alien beauty (who has electric powers and is deathly jealous, to boot — just do the math) for a fiancée. His main trait, though, is Cosmic Plaything considering how much he pays for this.
  • Childhood Friends: He's known Shinobu since they were in Kindergarten. In the anime, he's known the Stormtroopers since they were children as well, though their friendship is more vitriolic than most childhood friends.
  • Childhood Friend Romance: With Shinobu during early chapters… until she dumps him over his inability to get rid of Lum.
  • Class Representative: Gets elected class president as a Dork Horse Candidate to prevent Mendou from coming to power. He's so ineffective that later on, everyone had forgotten it.
  • Commitment Issues: He does love Lum, but he hates the idea of settling down with only one girl.
  • The Corrupter: If he's hanging with a male who doesn't know any better, Ataru likes to bring them down to his level and teaches them about women...from the perspective of an irredeemable lech.
  • Cosmic Plaything: He was born on the second unluckiest day in the Japanese calendar: The thirteenth of April – the fourth month of the year, as well as the day remembering the death of Buddha. His name means "hit by a shooting star", which would take phenomenally bad luck.
  • Crazy Jealous Guy: He won't admit it, even to himself, but he does not like seeing Lum with other guys.
  • Crouching Moron, Hidden Badass: He can stop Air Jousting Benten and Ryuunosuke in one move using bathing implements, in midair. He can also run 100m in 7 seconds as long as there's a girl involved.
  • Deadpan Snarker: Often tends to make snide remarks at other characters, especially Mendou or Ten.
  • Determinator: Whenever something tries to get between him and a cute girl or if he's faced with the chance of losing Lum, there's nothing that will stop him from getting what he wants.
  • Dork Horse Candidate: In Shuutaro Mendou's introductory episode/chapter, Mendou runs for class president on the platform of draconian punishments for misbehavior… except not for the girls (this is all it takes to win the vote of every girl in class). Ataru is pressed into running against him by the boys, leading to a tied vote. To resolve that, they duel and Ataru wins, making Mendou the vice president.
  • Dude, Where's My Respect?: He saved the world in the first episode/chapter, and Shinobu had promised to marry him in reward. Not only is he treated as a nuisance even by his parents, but Shinobu went back on her promise.note 
  • Dumbass No More: In the early chapters, he's very much an Idiot Hero who hardly ever does anything smart. In later chapters, he's portrayed as a perverted but cunning trickster who regularly outsmarts people, and only has Idiot Ball moments when he's lusting after girls (very often, but still).
  • Everyone Has Standards: In Movie 1, he rejects Elle for being a Harem Seeker who collects handsome young men and keeps them in carbon freeze. But mainly for being much more of a man-eater than he is a womanizer.
  • The Friend Nobody Likes: Apart from Lum, none of the other characters like him that much. The guys are jealous of his relationship with Lum and the girls can't stand his perverted behavior. And Lum's cousin Ten hates him because he is an "idiot".
  • Frying Pan of Doom: His weapon of choice against Jariten, since it doubles as both a shield from Jariten's fiery Breath Weapon and a pounding club.
  • Harem Seeker: His stated goal in life is creating his own harem with all of the attractive girls he knows. However, after seeing a reality where he gets a harem in exchange of Lum leaving him, he realizes he doesn't want a harem if Lum isn't in it.
  • Hormone-Addled Teenager: Played straight to an insanely ridiculous extent. Most teenagers in the series are like this, but none are as shameless as Ataru.
  • Idiot Hero: A very obvious example of the typical lazy and idiotic Japanese protagonist. Though he's not actually stupid, being rather intelligent but a complete slob.
  • Insufferable Imbecile: He's a selfish pervert, and has several Idiot Hero traits to the point that he's considered a Dumbass Teenage Son even by his own parents. However, he becomes less dumb as the series goes on.
  • Interspecies Romance:
    • He's a human guy who is chased after by an unwanted wife, Lum, who's an Oni. He has also chased after Oyuki (Neptunian), Benten (unnamed alien), Kurama (half-human half-karasutengu), Ran (vampire-like alien) and Elle (human alien), amongst others.
    • Subverted in an early manga chapter when he seemingly becomes the love object of a female kappa, who basically looks like a slender, long-haired humanoid turtle. Ataru had absolutely no interest in her.
  • Iron Butt-Monkey: It's even lampshaded in one book, where he gets a broken arm, and everyone is in disbelief.
  • Jerkass Has a Point: He may be a Jerkass, but he has every right to be annoyed by Lum. She's the one who assumed Ataru wanted to marry her (when all he said was "Now I can get married", referring to Shinobu), and basically intruded on every aspect of his life since then, acting like a possessive Clingy Jealous Girl.
  • Jerk with a Heart of Gold: Ataru is very lecherous, lazy, rather selfish, and stubborn, but he has deeply buried noble qualities that most people, including himself, can't see. Most of all, it's shown many times he genuinely has a good heart and cares about people, especially Lum.
  • Kavorka Man: He's considered by most girls to be the most undesirable boy in Tomobiki – unattractive, lecherous, obnoxious, selfish, and a Jerkass to boot, but he does get the affections of a few attractive girls, most notably the beautiful Alien Princess Lum.
  • Loser Protagonist: Mainly because of his lechery and other human faults. He was born on the most unlucky day of the year in Japan. His own parents often have no shame in saying how much they wish he wasn't born. He's unpopular with most of the boys and almost all the girls at his high school. Even when the beautiful female alien, Lum, comes into his life, he's still unlucky because of all the baggage she brings with her.
  • Lovable Sex Maniac: In the 10th anniversary movie Always My Darling, Princess Lupika's computer pinpoints him as the most lecherous man in the universe.
  • Love You and Everybody: In the rare occurrence where he admits he does want Lum, he'll proceed to list all the girls he plans to include in his harem.
  • Meaningful Name: Ataru means "to get hit" and Moroboshi means "falling star". A metaphor for his cosmically miserable luck. Several opening and ending themes show a star smacking him in the head at the end.
  • Noble Male, Roguish Male: The roguish to Mendou's noble. However, it's subverted to an extent since deep down Mendou is just as roguish as Ataru.
  • No Guy Wants to Be Chased: He's always chasing women who want nothing to do with him, yet tries to get away from the only girl who is always chasing him because she's a bit too possessive for his taste.
  • No Sense of Personal Space: He does it on purpose when he's flirting, and really enjoys it, even though he will always receive a violent punishment for it a second later.
  • Offscreen Teleportation: In the later half of the manga, he can basically appear out of nowhere to hit on a girl and/or troll Mendou.
  • Other Me Annoys Me: In Inaba's introductory arc, Ataru becomes disgusted with one version of himself in a future where he succeeds to create his own harem by chasing Lum away through treating her more poorly than usual without a shred of guilt or remorse, to a point Ataru considers that version of himself a Slimeball who is more selfish than his current self.
  • The Peeping Tom: He is far from being above spying on women who are changing, bathing, or otherwise completely or nearly naked.
  • Red Oni, Blue Oni: The brash and impulsive Red to Mendou's calm and polite Blue.
  • Significant Birth Date: He was born on April 13th, the second-unluckiest day of the year in the Japanese calendar, and in the year he was born was also the anniversary of the Buddha's death.
  • Smarter Than You Look: He’s frequently referred to as stupid and is considered the village idiot by nearly everyone (including his own parents and sometimes Lum herself). But despite his usual foolish behavior, he can be quite cunning and resourceful. He has managed to outwit nearly everyone else in the cast at least once.
  • The Trickster: Eventually evolves into this. Lampooning authority and making basically everybody around him look as foolish as he does.
  • Tsundere: At first, he clearly can't stand Lum, but becomes attached to her as he does find her cute when she acts more normal. Later in the series, it becomes obvious that he cares about Lum, although he is still too proud to admit it and usually only shows his true feelings when he's afraid of losing her.
  • Unlucky Everydude: He falls behind in the "Everydude" part, though, seeing as how he's a Determinator and Lovable Sex Maniac of such intense perversion he's outright stated to be the most concentrated source of lust in the known universe. He comes off as average because everyone else he hangs out with is even more bizarre…
  • Unrequited Love Switcheroo: Ataru was actually attracted to Lum the first time he meets her, while Lum was indifferent to Ataru's shameless flirting. Lum falls for Ataru only after he defeats her in the game and, due to a misunderstanding, assumes he wants to marry her. From that point on, Lum is madly in love with him, while Ataru finds her annoying and only wants to avoid her.
  • Unsympathetic Comedy Protagonist: While he has his redeeming qualities (deep down), Ataru is a Jerkass and deserves about 80% of what happens to him. However, the rest of the cast isn't much better than him.
  • Vitriolic Best Buds: With Mendou.
  • Weirdness Magnet: The name of the series itself can be translated as "Those Annoying Aliens", suggesting that the galaxy and series' version of Earth is teeming with sentient species who are all irritating in their own ways. Ataru is therefore simply unlucky enough to catch the attention of all of them.
  • Will They or Won't They?: With Lum. They're technically engaged, but Ataru refuses to go through with the marriage because he prefers to hit on every other cute girl he encounters. While it's repeatedly made clear he does want Lum in his life, we never get to know whether they'll ever be able to have a stable relationship.
  • Wouldn't Hit a Girl: At least, he wouldn't beat up a girl and, as seen in one of his rare Pet the Dog moments, he would even physically hurt himself rather than hurt Lum.


"Darling no BAKA!!"

Voiced by: Fumi Hirano (JP, original series), Sumire Uesaka (JP, All-Stars), Shannon Settlemyre (EN, Movies 1,3-6), Martha Ellen Senseney (EN, test dub), Roxanne Beck (EN, Movie 2), Anna Friel (BBC gag dub), Claudia Thompson (EN, Animax Dub)

The female protagonist of the series. Lum is a beautiful Oni Alien Princess who can fly and can generate electricity from her body, up to and including lightning bolts. She falls in love with Ataru after she misinterprets his "marriage proposal" (referring to Shinobu) as one for her. Most of the time she's good-natured, sweet, innocent, and faithful… but she's also prone to intense jealousy and has a very hot temper, which never bodes well for her "fiancé".

  • Abhorrent Admirer: Downplayed. Lum is a beautiful and charming Alien Princess who is totally head over heels in love with Ataru, but she also is extremely jealous, possesses an explosive temper and is not afraid to use her explosive lighting powers on her "husband" whenever he tries hitting on other woman or just upsets her. Meanwhile, Ataru tries to stay as far away from her as he can help it. It's an interesting case, as Ataru is sincerely attracted to Lum, but her demands to be the only girl in his life, as well as intruding on all aspects of it, is what keeps him from returning her affections.
  • Adaptation Dye-Job: In the colored manga artwork, Lum was originally given iridescent hair; the difficulties faced in animating this caused the anime to replace it with a solid dark green color, which was later used in the manga as well. The 2022 anime looks to be going back to iridescent hair, though still primarily green.
  • Alien Catnip: Thanks to Bizarre Alien Biology, she often gets famously smashed from eating umeboshi (pickled plums).
  • Alien Lunch: Oni have a much greater tolerance of spice than humans. She comments that Earth-food is completely flavorless and enjoys drinking Tabasco sauce straight out of the bottle. As a result, things go poorly when she tries to give Ataru some of her home cooking.
  • Alien Princess: She's the princess of the Oni planet and has plenty of gadgets of advanced alien technology.
  • Arranged Marriage: With Rupa. Their great-grandfathers made an arragement that their descendants would get married when a girl was born in Lum's family.
  • Bare Your Midriff: Obviously. Her Iconic Outfit is a tiger-print bikini.
  • Belligerent Sexual Tension: With Ataru. Their basic dynamic is Ataru pissing her off by ignoring her and harassing other girls, which always results in Lum electrocuting him. Even though Ataru does have feelings for her, both are too stubborn to make their relationship stable.
  • Betty and Veronica: In the early parts of the series, Lum plays the Veronica to Shinobu's Betty. Completely opposite to Ataru's childhood friend Shinobu, Lum is a skimpily dressed, hot alien girl who falls for Ataru and tries to forcefully make him hers only. Once it was decided that Lum was going to be the main heroine instead of Shinobu, the Love Triangle was dropped.
  • Beware the Nice Ones: She's quite sweet-natured, but that doesn't stop her from (non-fatally) electrocuting Ataru whenever he does anything perverted… which is nearly all the time.
  • Big Sister Instinct: Lum is very protective of Ten, especially when Ataru picks on him, but she also scolds him sometimes when he’s being too much of a brat.
  • Birds of a Feather: It's subtly hinted that part of the reason why Lum is attracted to Ataru (the other part being that she can recognize his deeply buried noble qualities) is because they're much the same; Lum is also sneaky, mischievous, bad-tempered, and uninhibited. Also, in a way, she can be a bit of a lecher herself (though not at his level) and her ways of pursing him are a more downplayed example of how he asks girls out. She is constantly glomping him and invading his personal space, trying to steal kisses from him, make him take her out on dates and hates it when another woman gets his attention... which are things that Ataru has done in the past when he is girl hunting. Then there's her brazen offer of sexual activity, making it clear that if Ataru wanted to have sex with her, she would be more than happy to give it to him.
  • Breakout Character: She was supposed to be a One-Shot Character, but fans (and Takahashi's editor) loved her so she returned in the third chapter and became a Deuteragonist, love interest, and poster girl for the series. In many foreign adaptations, she also becomes the title character and she's often believed to be the main character due to this. To this day, she remains one of the most recognizable comic characters ever created.
  • Catchphrase Insult: Whenever Ataru angers her, Lum yells "Darling, you idiot!" or "Darling, I hate you!"
  • Characterization Marches On: Early chapters of the manga portrayed her as a clear-cut antagonist, if not an outright villain. Needless to say, her characterization wildly changed before the manga was even a single year old, making her the short-tempered yet more likable character we are familiar with. This very likely has something to do with the fact that Lum wasn't originally meant to be the main heroine, but an obstacle for Ataru's relationship with Shinobu, but Lum's popularity forced Rumiko Takahashi to change the Official Couple.
  • Childhood Friends: With Benten, Oyuki, and Ran.
  • Clingy Jealous Girl: She is very possessive of Ataru and usually zaps him with lightning as a punishment for his "infidelity".note  She also intentionally torpedoed his relationship with Shinobu out of pure jealousy. And in the first movie, she nearly started an intergalactic war to keep him from marrying another Alien Princess.
  • Closet Sublet: The Trope Codifier. She lives in Ataru's closet (possibly a pun on the Japanese slang for Pretty Freeloader). She's sometimes shown living in her spaceship at times, however.
  • Cool Big Sis: To Ten, although she's actually a Cool Big Cousin, but she treats him like a little brother.
  • Covert Pervert: She might not be at Ataru's level, but it's been hinted at times that she can be a bit of a lecher herself, though it's only towards him. It's implied that she wouldn't mind Ataru's perversions if he only did it towards her and no one else.
  • Crazy-Prepared: Lum nearly always carries around some kind of weird alien device useful to the situation at hand (but usually it makes the trouble one hundred times worse).
  • Cross Cultural Kerfuffle: Lum's limited understanding of human society is a common recurring problem between herself and Ataru. One notable early example is at the start of the 4th volume; when she gets mad and zaps her Stormtroopers, who then claim it feels good to be zapped by her, she wonders if this means Ataru is a "deviant" for not enjoying her zapping. She promptly electrocutes him into unconsciousness to try and "cure" him, only to then learn, to her horror, that humans can die from being electrocuted.
  • Cute Little Fangs: Has them. However, when she gets angry and screams, we see she's got an entire mouth full of them.
  • Cute Monster Girl: Lum looks like a cute teenage girl with green/iridescent hair and little horns, but is explained as being an alien whose race is the inspiration for Oni. Her being such is actually lifted straight from Japanese mythology, where Oni women are supernaturally beautiful but capable of assuming fearsome visages when angry or jealous.
  • Defeat by Modesty: How Ataru defeated her in the tag game. He stole her bikini top and this made Lum let her guard down long enough for him to catch her horns.
  • Demon Head: On rare occasions, when extremely angry, Lum's face takes on a more monstrous mien with prominent fangs and sometimes even elongated horns.
  • Depending on the Writer: Her own view on her "marriage" to Ataru. At times, she insists they are married in every possible way and views him as her husband, yet when given the chance, she will try to drag him down the aisle.
  • Deuteragonist: The female lead character and love interest of the protagonist.
  • Double Standard: Abuse, Female on Male: Lum uses her electricity to shock Ataru multiple times a day.
  • Dude Magnet: Almost every named male teenager in the series is in love with her, and therefore intensely jealous of Ataru. Even Rei, despite being only interested in food and largely indifferent about girls, is seemingly in love with her. Ironically the only one who is not interested in her is Ataru himself, or so it seems (deep down he is).
  • Everyone Has Standards: She is a Love Martyr who is eternally devoted to a loser like Ataru, getting a What Does She See in Him? from everyone. However, it's revealed that her ex-boyfriend Rei was even worse (a complete idiot and even more selfish than Ataru) and Lum actually broke up with him because she couldn't stand his behavior. This proves that she still has more standards than many other girls (especially Ran) who are more than willing to date someone like Rei, just because of his good looks.
  • Exposed to the Elements: Although Lum might sometimes don winter clothes, it's more to fit in than from any need of protection. She's seen wearing her tiger bikini whatever the weather, including while flying on a windy, snowy night, with no sign of discomfort.
  • Forceful Kiss: She has kissed Ataru, whether he wants it or not.
  • Fur Bikini: She wears a tiger-striped bikini (based on the tiger-striped loincloths of mythical oni, which were made out of man's bad karma). It is her Iconic Outfit.
  • Genki Girl: She has a cheerful but feisty personality.
  • The Glomp: To Ataru. Usually accompanied by a painful electric shock.
  • Horned Humanoid: Being an Oni, she has two small horns.
  • Horrible Judge of Character: Ataru is certainly better than her ex-boyfriend, but he's still pretty terrible to her. But she still thinks he's her One True Love and nothing will make her change her mind.
  • Human Alien: Lum and her family look almost exactly like humans, only with two small horns and green hair. Well, her dad just barely makes the cut.
  • Instant Fanclub: Lum's Stormtroopers, a band of losers from Ataru's class who instantly became enamored with Lum.
  • Interspecies Romance: She's an Oni alien who is in love with and wants to marry a human, Ataru. She was also engaged to marry a guy from a different race of Human Aliens, Rupa, when they were children.
  • Jerk with a Heart of Gold: Lum is clingy, possessive, controlling, and can get violent when she's angry. But she's also sweet and loving towards the people she cares about. In later chapters she Took a Level in Kindness and, despite her many flaws, she's a friendly and nice person (nicer than Ataru, at least, who still remains a Jerk with a Heart of Gold).
  • Kaleidoscope Hair: In the manga's colored pages, she was given iridescent hair. Changed in the anime to its iconic green because iridescence was next to impossible to animate in 1981 (and is still extremely difficult today).
  • Kiss-Kiss-Slap: She's very affectionate to her 'Darling', but doesn't hesitate to zap him with lightning whenever he hits on another girl, which happens a lot.
  • Lethal Chef: There's nothing technically wrong with her cooking; it's just that she tends to overuse the spices to make it taste like the food on her home planet (and by Oni standards, she's actually a good cook).
  • Light Feminine and Dark Feminine: The sexually aggressive Dark Feminine to Shinobu's demure Light Feminine.
  • Limited Wardrobe: Aside from her school uniform and occasional street clothes, the only outfit she owns is her trademark bikini and go-go boots combo. When it gets stolen by Tobimaro and his henchwomen, Lum angrily chases them down while screaming about how that's her only good set of clothes.
  • Love Hungry: She is very desperate for Ataru's love and has done rather questionable things in order to have him all to herself.
  • Love Martyr: Ataru is lecherous, obnoxious, selfish, and a Jerkass to boot, but Lum still loves him and would do anything for him despite how he's often rude to her and would have no problem groping/flirting with other women, even in front of her.
  • Love Revelation Epiphany: She fell in love with Ataru after she misinterpreted something he said to himself as a marriage proposal to her.
  • Magical Girlfriend: A famous parody. Ataru is an Unlucky Everydude whose life gets turned around when the beautiful alien princess Lum falls in love with him. Ataru is also a slovenly, pitifully-desperate pervert who usually deserves all the trouble he goes through, and Lum is a Tsundere/borderline-Yandere who loves him despite his lechery but isn't averse to zapping him with her electrical powers when he strays. She's also somewhat bumbling, usually causing more problems than she solves. Add to this that when she showed up, he already had a girlfriend he liked better.
  • Meaningful Appearance: Early on, Ataru forces Cherry to give him a set of yellow ribbons that, if tied around Lum's horns, make her lose her powers.
  • Modesty Shorts: A teacher once gave her a pair of gym shorts to wear under her skirt after noticing that she was flashing her classmates whenever she would fly.
  • Monster Roommate: Zigzagged. Depending on the chapter, she switches from living in Ataru's closet to staying in her spaceship.
  • Mood-Swinger: Lum is a very sweet, innocent, faithful, and good-natured girl, but she can also be jealous and has a very hot temper.
  • Ms. Fanservice: One of the most famous. She is a beautiful alien princess who wears a tiger-striped bikini, and Ataru stealing her bikini top leaving Lum with her naked breasts exposed in the first episode is one of most iconic scenes in the anime world.
  • Never Gets Drunk: Due to Bizarre Alien Biology, alcohol has no effect on her, so she can outdrink any human.
  • No Accounting for Taste: No-one can figure out why such a beautiful girl as Lum is in love with a lecherous loser like Ataru. This includes Ataru himself.
  • No Sense of Personal Space: Early in the series, she's very touchy with Ataru, eager to smother him in hugs and kisses at any given chance (whether he wants it or not). It's downplayed after Character Development.
  • Nurse with Good Intentions: As Ran knows from experience, whenever her friends are ill she comes to help... but only causes more trouble, up to blowing up their home.
  • Parental Substitute: To her little cousin Ten. In a way Lum is the only consistent mother figure he has ever had in his life. She's his legal guardian and takes care of him almost as if he was her child.
  • Pretty Freeloader: She stays for free at Ataru's house.
  • Required Secondary Powers:
    • Alongside with her ability to generate electricity, she's naturally immune to electric shocks herself. She in fact can absorb electricity from other sources, which can result in her getting supercharged — afterward, she'd shock anybody she'd touch, even involuntarily, until enough is discharged. Of note is that her iconic tiger-striped bikini is impervious too; in one occasion, generating a stronger discharge than usual has vaporized her clothes, but not the bikini she uses as underwear. This certainly explains why she's so attached to it.
    • Additionally, when questioned about her attire while out in a snowy landscape, Lum replies she is extremely resistant to cold and wind. This makes sense as she's commonly seen flying high up in the sky in the aforementioned bikini, perfectly comfortable, despite being Exposed to the Elements.
  • Second Love: She and Ataru are this to each other. It's played with: Lum openly loves Ataru and flat-out hates her First Love Rei, but Ataru would never admit that he loves Lum and still tries to win his ex-girlfriend back (while hitting on all the other girls he meets).
  • Self-Proclaimed Love Interest: She considers herself to already be engaged/married to Ataru, even though he flees at the mere mention of marriage and commitment from her.
  • Shock and Awe:
    • Lum (and her mom) can generate electricity, both shocking whoever they touch and launching lightning bolts from their fingers. Lum routinely uses this to punish Ataru for angering her, but she can't entirely control it, resulting in the obvious implication that Ataru's hesitance to get near her is partially due to her tendency to shock him accidentally when she hugs him or tries to sleep in his bed.
    • One chapter shows that she actually will generate electricity as a form of affection. In the chapter, she will fall for whoever holds her heart and act like a smitten teenager around that person. Several people got her heart, but she only electrocuted Ataru, even claiming that to be special exclamation of love.
  • Single-Target Sexuality: While she has an ex-boyfriend (Rei, whom she can't stand), Lum never shows interest in anyone but her "Darling" throughout the series.
  • Spotlight-Stealing Squad: To the point that, when Ataru tries to give up one of his positions (class representative) and everyone assumes he's giving up his spot as the main character, she says it can't be that because SHE is the main character.
  • Stalker with a Crush: Some of her behavior can come like this at times, such as constantly following Ataru around, ruining his dates/flirting and even forcing him to let her live with her are some examples.
  • Strong Family Resemblance: Lum and her mother look very similar to each other.
  • The Tease: Early in the series, she tries to get Ataru to sleep with her, only to be denied by him, even waving her bikini top in the air while she laid under the covers of the futon. Another instant is when she and Ataru are fighting, as in a "roughhousing" sort of way, Lum only complains that he should just let her pull out the futon first.
  • Town Girls: She's neither tomboyish nor girly when compared to the demure Oyuki's Femme and the tomboyish Benten's Butch.
  • Tsundere: Sweet type. She's very sweet and affectionate, but Ataru chasing other girls brings out her hot-tempered and possessive side.
  • Turn the Other Cheek: She always forgives people who are close to her, even if they always treat her badly, like her "boyfriend" Ataru or her childhood "friend" Ran.
  • The Ugly Guy's Hot Daughter: The huge, monstrous king of the alien Oni looks nothing like his green-haired bombshell of a daughter, Lum, who definitely takes after her mother.
  • Unwanted Spouse: Ataru is engaged to Lum because of a misunderstanding and he's very open about not wanting to marry her.
  • Verbal Tic: "-datcha" (or "-tcha") at the end of almost every sentence.
  • Victoria's Secret Compartment: She occasionally pulls some Oni-tech gizmo from her bikini top.
  • Walking Swimsuit Scene: When she isn't wearing her school uniform or street clothes, her default outfit is her tiger-patterned bikini and go-go boots. The tiger pattern is a reference to how oni are typically depicted wearing loincloths made of tiger skin.
  • Well, Excuse Me, Princess!: A Trope Codifier. While Lum actually doesn't really mind Ataru being a pervert, she would like him to do better with his life instead of just being a lecherous loser. She would also much rather Ataru act like that toward her rather than every girl except her.
  • What Does She See in Him?: No one seems to understand why Lum is in love with Ataru, particularly her many admirers. For the record, Ataru has no idea either.
  • Will They or Won't They?: With Ataru. For the entire series, Lum is trying to get Ataru to marry her with no success. She does get several proofs of Ataru wanting to be with her, but she just can't ever get him to admit he loves her.
  • Yandere: While it's Played for Laughs, she's determined to keep Ataru to herself no matter how much it literally hurts him or others. This includes jamming his phone conversations, throwing things at him or beating him up when she is not electrocuting him, blackmailing him with the world's entire oil supply to force him into letting her live with him, drugging him with a love potion to keep his eyes on her only and at one point, even traveled back in time to train his younger self to be more obedient and faithful to her.

     Shinobu Miyake


Voiced by: Saeko Shimazu (JP, original series), Maaya Uchida (JP, All-Stars), Danielle Sullivan (EN, Movie 1, 3-6), Katherine Burten (EN, test dub), Jeannette Ann Wallace (EN, movie 2), Lauren Laverne (EN, BBC gag dub), Andrea Kwan (EN, Animax dub)

Ataru's childhood friend and classmate. Until Lum showed up she was also Ataru's girlfriend. As encouragement for Ataru during the tag game, she promised him that if he won she would marry him. This did indeed spur him to victory, but it also resulted in his victory cry that led to Lum deciding to stay and claim Ataru instead.

Shinobu is a neat, sweet, petite young lady of above-average physical attractiveness. Despite these very feminine characteristics, however, she has an extremely short temper and often displays superhuman strength — she's one of the strongest characters in the series, able to easily throw classroom desks or any other large/heavy object/structure on-hand as needed.

  • Betty and Veronica: The Betty to Lum's Veronica. She serves as the down-to-earth childhood friend to Ataru who dated him first, in contrast to the glamorous and sexy alien Lum who spends the early parts of the series trying to steal Ataru away from Shinobu. This lasted until the romantic relationship between Shinobu and Ataru was abandoned so Lum could be the main heroine.
  • Beware the Nice Ones: Shinobu usually acts like a cute, fragile teenage girl who still likes to speak her mind. However, when her temper is pushed too far, she gets violently mad, easily able to lift heavy objects and throw them at her target (usually Ataru).
  • Brainy Brunette: She has brown hair and it's mentioned she's a pretty good student.
  • Catchphrase Insult: "Men be damned!"
  • Childhood Friends: She has known Ataru since they were kindergarteners. In the anime, Shinobu has also known the Stormtroopers since she was seven.
  • Childhood Friend Romance: She's Ataru's childhood friend and on-again-off-again girlfriend during the early part of the series. By the time Lum establishes herself as the female protagonist, Shinobu becomes a regular friend to Ataru.
  • Clingy Jealous Girl: Early chapters have her constantly fighting with Lum over Ataru, as well as punishing him for always chasing after other girls.
  • Cute Bruiser: She is a cute girl, but also inhumanly strong.
  • Demoted to Extra: Thanks to Lum becoming the Breakout Character and replacing her as the other half of the Official Couple, Shinobu loses prominence later in the series. In early stories, she's The Rival to Lum for Ataru's affections, but eventually loses interest in him and becomes just The Generic Girl who often hangs out with Ataru and his friends.
  • Engagement Challenge: She used this to encourage Ataru during the game of tag. It worked, but it led to Ataru's Accidental Marriage with Lum.
  • Fatal Attractor: The only guys who have any interest in her are creeps and weirdos. Fortunately, she meets Inaba near the end of the series.
  • First Love: She and Ataru were this to each other, but they eventually get over it.
  • Girl Next Door: Ataru's pretty-but-down-to-earth childhood friend.
  • Girly Girl with a Tomboy Streak: She genuinely tries to be a serious, polite, and ladylike girl who thinks about romance and wants to find the best boy for her. However, her bad temper and violent tendencies combined with Super Strength are not very ladylike.
  • Hair-Trigger Temper: She has a tendency to get angry and overreact to the littlest things.
  • Hopeless Suitor: Toward Mendou. He ends up disappointing her because he only has eyes for Lum.
  • I Can Change My Beloved: Early in the story, it was obvious Shinobu really cared about Ataru. Unlike Love Martyr Lum, she actually wanted him to change his obnoxious ways and become a better person (Lum wouldn't mind Ataru's perversion if he directed it toward her). This obviously never happens and Shinobu gradually loses interest in him.
  • Light Feminine and Dark Feminine: The demure Light Feminine to Lum's sexually aggressive Dark Feminine.
  • Looking for Love in All the Wrong Places: She certainly has bad luck with men.
  • Meaningful Name: Shinobu means "to endure" and she truly has endured a lot.
  • Megaton Punch: A specialty of hers, particularly towards Ataru and Soban.
  • Nice Girl: She's usually very kind and friendly, at least when you don't make her angry.
  • Official Couple: She starts dating Inaba towards the end of the series.
  • Only Sane Woman: When not angry, she is one of the most normal characters, at least compared to the rest of the cast.
  • Shipper on Deck: Strangely enough, she eventually becomes this for Ataru and Lum. In a later episode, when she hears the rumor that they are about to break up, she fears that Lum could start to like Mendou instead, so she teams up with the girls of the class (who all want a chance with Mendou) to make Lum stay with Ataru.
  • Single Girl Seeks Most Popular Guy: Her crush on Mendou is this (and she's pretty enough to at least get him to consider her). Averted with her ex, Ataru, who is about the least popular guy in school.
  • Single Woman Seeks Good Man: Ends up with Inaba, who is probably the only truly nice character in the series.
  • Super Strength: Her super-strength evolved from sight gag to full-fledged superpower.
  • Throw the Dog a Bone: After having such terrible luck with men throughout the series, she finds a true Nice Guy to be her boyfriend.
  • Took a Level in Kindness: In the first volume of the manga, Shinobu is a lot nastier, being short-tempered, violent, suspicious and distrustful of Ataru even before Lum arrives.
  • Tsundere: Sweet type. She's normally nice and sweet, but she's also short-tempered and violent.
  • Yamato Nadeshiko: She considers herself a responsible and ladylike Japanese girl. She's not completely this because of that temper.

     Shutaro Mendou

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

Voiced by: Akira Kamiya (JP, original series), Mamoru Miyano (JP, All-Stars), Robert Rogan (EN, Movie 1,3-6), Wayne Grayson (EN, Movie 2), Brian Hudson (EN, test dub), Russell Wait (EN, Animax Dub)

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 the face of Ataru, 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.

  • Animal Motifs: The Mendou family crest is an octopus, and Mendou himself keeps several as pets. Furthermore, he is offended if people eat takoyaki in his presence.
  • Arranged Marriage: With Asuka.
  • Bishōnen: The greatest difference from Ataru is that Mendou is a pretty boy who is so handsome he almost looks like a woman.
  • Broken Ace: Introduced as The Ace (and his clueless fangirls still see him as such), but it's very obvious he's anything but. He frequently makes a fool of himself, especially when he's being too vain or Holier Than Thou, and Ataru is able to use Mendou's claustrophobia and ego against him.
  • Bodyguarding a Badass: Even before he levelled up to get Super Strength, he was always more formidable than his hordes of incompetent, foolish sunglasses-wearing security forces. It's so bad that the security team actually begged Mendou to protect them from Asuka when she was rampaging at the Mendou residence. That said, they are loyal and will gladly do whatever minor but labor-intensive job Mendou requests of them.
  • Butt-Monkey: His claustrophobia and fear of the dark put him in embarrassing situations as a Running Gag. He also gets caught up in almost as much slapstick humiliations as Ataru (such as when rumour-spreading alien flowers convinced the whole town, including Shinobu, that Mendou is a bedwetter).
  • Charles Atlas Superpower: He apparently developed it while trying to escape from all the bells Ataru closed him into.
  • The Charmer: In contrast to Ataru, he knows how to approach a woman, thanks to his suave and sophisticated manners.
  • Chick Magnet: He is very popular with all the girls at school… except Lum, the only girl he wants.
  • Claustrophobia: Except anytime a hot girl's looking at him – his ego is stronger than his fear.
  • Custom Uniform: He wears a white gakuran instead of the standard black one other male students wear, just to show off how rich he is.
  • Ditzy Genius: It's mentioned in the manga that he's an Academic Athlete who does well in school, but he doesn't seem smarter than pretty much anyone else in the cast, except maybe Rei. In fact, he's prone to Idiot Ball moments just as much as Ataru and it's frequently lampshaded (though his female classmates would disagree). In later chapters, even Ataru appears to be more clever than him, despite being less charismatic.
  • Foil: To Ataru. Ataru comes across as a moronic, lecherous, selfish jerk but he has more Hidden Depths and Hidden Heart of Gold than expected. By contrast, Mendou seems a handsome, suave, smart gentleman, but he's actually just as petty, foolish, and lecherous as Ataru, and in many ways is an even bigger jerk.
  • The Friend Nobody Likes: Downplayed. In his class, all the girls (except Lum) love him but all the guys hate him. Out of the people he frequently hangs out with (Ataru, Lum, Shinobu, Ten, Sakura, Megane, etc.), only Shinobu likes him.
  • Gentleman and a Scholar: Downplayed. Mendou is responsible, one of the best students in the class, and acts polite and well-mannered to girls, but he's too much of a stuck-up Spoiled Brat to qualify.
  • Handsome Lech: Mendou is the same as Ataru, except he's rich, handsome, and suave.
  • I Hate Past Me: In one chapter/episode Mendou traveled back in time and very literally scared his younger self — the child Mendou acted like such an obnoxious brat to his future self that he provoked the latter into attacking him with a sword. The young Mendou hid in a jar until the older Mendou returned to his own time, but that experience was what gave him his claustrophobia and fear of the dark ("WAAAN! KURAI YO SEMAI YO KOWAI YO!"). And what's more, the reason he traveled back in time in the first place was to prevent himself from getting that claustrophobia and fear of the dark.
  • Iconic Sequel Character: He is Ataru's main foil/rival, the second most important male character, and probably the Tritagonist of the entire series (replacing Shinobu in that role), but he isn't introduced until the third volume.
  • Inferiority Superiority Complex: Anytime he finds himself second best at something he feels he should be best at, he tends to collapse - The time Rei turned up and was better looking then him (Mendou's response after coming out of shock "Money is more important than looks!!"), and all the times Ryuunosuke winds up getting a bigger pile of fan mail then him.
  • Instant Fanclub: His army of fangirls sprang up the instant he arrived, since he's handsome and rich.
  • Jerkass Has a Point: The most malicious thing he ever did (In the anime version at least) was taking advantage of Lum's amnesia and claiming she is his fiancée (thus taking advantage of a woman to a degree that not even Ataru would ever do), he does out of disgust towards Ataru's apathy concerning Lum's disappearance. Even then, it takes Lum's Stormtroopers to convince Ataru to get his head in the game.
  • Katanas Are Just Better: Subverted. On said occasions, Mendou draws his katana (in the anime it is called Murasame) and attempts to slice Ataru in two, but he never succeeds.
  • Ladykiller in Love: Maybe for Asuka. His relationship with Lum also has this vibe.
  • Last-Name Basis: Everyone calls him Mendou. (except Lum)
  • Lord Error-Prone: He's incredibly wealthy, carries a sword everywhere he goes, and generally acts the cool sophisticate, an act for which the local girls fawn over him in adoration. Scratch the gloss, however, and he's really no better than Lovable Sex Maniac Ataru Moroboshi himself. In fact, he's arguably worse, given that he's utterly afraid of the dark, claustrophobic, and a Dirty Coward, while Ataru is capable of insane acts of bravery and determination.
  • Madness Mantra: "Waah, it's dark! I'm scared!" he'll break into this line and keep repeating it while he's trapped in a dark, cramped space.
  • Meaningful Name: Mendou means "trouble".
  • Mirror Character: Take away his power and sophisticated manners, and Mendou is the same as Ataru. If anything, one could argue that he's worse, since Ataru has a noble side he buries deep down, whilst Mendou, under his superficial charm, is an arrogant, self-entitled lech who looks down on his own gender, is blatantly biased in favor of women, and is a Dirty Coward.
  • My Sister Is Off-Limits!: Tends to beat up any guy that shows interest in Ryoko. Ryoko takes advantage of this by pretending to be interested in other guys (usually Ataru or Tobimaro) to arouse her brother's wrath on them.
  • Noble Male, Roguish Male: He acts as the noble to Ataru's roguish. However, deep down Mendou is just as roguish as Ataru.
  • Perfectly Arranged Marriage: After seeing how she really looks like under her armor, Mendou becomes very motivated to marry his arranged fiancee Asuka. Asuka, on the other hand, comes to accept him after she finds out he's a "big brother" like Tobimaro.
  • Red Oni, Blue Oni: The calm and polite Blue to Ataru's brash and impulsive Red.
  • The Rival: He clashes with Ataru fairly often. At first, he appears to be the Always Someone Better to Ataru's loser, especially when it comes to girls, but their rivalry is actually balanced, as Mendou has his own weaknesses and Ataru knows that.
  • Royal Brat: Mendou is first introduced to the series proper by hitching a ride to school... in a massive heavy bomber jetplane, out of which he skydives while several jets/helicopters fly in escort. In the original manga, there is no escort, and he comes by helicopter instead of a bomber. That said, the helicopter used is the massive and extremely rare Mil V12, which just so happens to be the biggest helicopter ever made!
  • Screw the Rules, I Have Money!: Does this a LOT. In addition to commuting to school via aircraft, he regularly summons his family's private military to the school if something doesn't go his way.
  • Selective Obliviousness: Never realizes that his sister isn't being seduced by other men, and that actually she's pretending to be interested in other men to annoy him as part of her cruel games.
  • Sheltered Aristocrat: He's the pompous and mean-spirited buffoon kind.
  • Spoiled Brat: Shutaro might border on being a Royal Brat, due to the fact his family is insanely wealthy (among other things, they have their own private army and own a considerable chunk of Japan).
  • Token Rich Student: Mendou is the heir to the richest family in Japan, who has its own private army. He's frequently seen parachuting from his private jet to go to school, which is the same public high school of the main characters.
  • Took a Level in Jerkass: In a anime-original 2-parter story where Lum's UFO crashes on the Mendou estate, causing her to lose her memory. Shutaro takes advantage of this by claiming her as his fiance and then isolating her from outside contact. When Lum's Stormtroopers get ready to launch a rescue mission, Megane even leaves behind his will as he does not expect to survive, and he's right as the Mendou private army is sent out to kill them!
  • Tyrant Takes the Helm: During his debut, he ran for the role of Class President, promising to install a torture chamber to punish tardy students, rip out the tongues of students found guilty of lying, and execute students who cheated! ...But only male students; the girls would be exempt, of course.
  • Vitriolic Best Buds: Whilst he and Ataru often do things together and even act almost like friends, neither of them likes or respects the other.
  • Why Did It Have to Be Snakes?: Due to a time-travel incident intended to actually fix his fears, he has horrible nictophobia and claustrophobia.

Tomobiki High School

     The Principal 

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

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

  • Cloud Cuckoolander: The principal has a very slow and proper way of talking and he has a tendency to spew out boring speeches about school spirit that never seem to go anywhere. In an early manga story, when he learns Ataru has been caught holding a secret vote on who is the most beautiful girl at Tomobiki in class, he decides to hold a schoolwide beauty contest... which promptly turns farcical by including an Eating Contest and an unarmed brawl against wild animals donated by the local zoo.
  • No Name Given: He is just "The Principal".
  • Odd Friendship: He is accompanied by the ghost cat Kotatsu-neko on almost every occasion.
  • Skewed Priorities: You'd think he should become irate over the constant alien invasions, destruction, parties, chases and such, but it doesn't really faze him at all. But be seen running in the halls and you'll be holding buckets of water.
  • The Stoic: He's a very calm old man who rarely acts in anger and always keeps a straight face.
  • Unfazed Everyman: All of the truly insane things that happen in the school every day don't seem to have any effect on him.

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.

  • Adapted Out: At one point in the manga, he refers to having a wife and kid at home, they're never mentioned again, and don't exist in the anime where he has a hopeless crush on Sakura.
  • Authority in Name Only: No one respects him, and is often abused or beaten up by Ataru or other students.
  • Big Ol' Eyebrows: Has some of the largest in a series full of 'em.
  • Butt-Monkey: No one at Tomobiki High has any respect for him. His students regularly ignore him, and then hogtie him if he tries to enforce the rules.
  • The Chew Toy: Bad things tend to happen to him. More often than not, those bad things tend to involve Amusing Injuries.
  • Hidden Depths: In the second movie, it's him that figures out the "Groundhog Day" Loop well before the rest of the cast, even Sakura.
  • Hopeless Suitor: To Sakura in the anime, unfortunately for him she is already in a relationship with Tsubame. His dream wife in Beautiful Dreamer even resembles her.
  • Hot for Student: In a few episodes, the students think Onsen is attracted to one of his students, though Onsen always turns out to be innocent.
    • When Ryuunosuke was taking lessons from Onsen to be a proper lady, her father, spread the slanderous rumor that Onsen was forcing her to date him.
    • One night, Shinobu watched a drama where a teacher was abusing his position to harass his student, unfortunately that happened to be the night Onsen was visiting the homes of all his students causing Shinobu to think he was pursuing her, Hilarity Ensues.
  • Jerk with a Heart of Gold: Despite being a very angry man, Mark really does have his students' best interests at heart, and is even one of the few adults to inquire about Fujinami's questionable parenting.
  • Not So Above It All: Onsen once admitted that he does enjoy the chaos Lum brings.
  • Only Known by Their Nickname: His real name is never revealed, with everyone (including the principal) calling him Onsen-Mark after his clothes, decorated with a hot spring mark. Maybe it really is his name? The English translated 2-in-1 manga even refers to him as "Hot Spring Emblem", because that's the literal translation of his nickname!
  • Only Six Faces: He bears a resemblance to an older Kakugari, as well as Lum's father without the fangs.
  • Sitcom Arch-Nemesis: To Ataru, one of the biggest slackers in his class.
  • Stern Teacher: Especially to Ataru, since they see each other as archenemies.
  • Villain Decay: Was a rather menacing Sadist Teacher in his debut, while later episodes made him more of a pathetic chewtoy with an underpaid job.

     Ryuunosuke Fujinami
Voiced by: Mayumi Tanaka (JP), Morgan Jarrett (EN, movies 3-5), Kimberli Wayman (EN, movie 2)

A student in Class 2-4 with Ataru et al. She was born a girl and sees herself as a girl, but her eccentric father raised her as a boy and calls her his "son", leading to her extremely masculine speech (and name). Her greatest desire is to behave appropriately for her gender.

  • Action Girl: Due to daily fights with her father, she is an excellent fighter. Basically, think of her as a proto-Ranma Saotome.
  • Ambiguously Bi: Due to Ryuunosuke's character concept being built around her gender issues, it can be interpreted that she might be a lesbian or bisexual:
    • In general, Ryuunosuke is more polite and demure around other girls, and more aggressive around other guys. But that can be explained by a combination of her admiration of other girls for being more feminine than she is, as she wishes to be more like that, and her reacting negatively to the various perverts, lechers and weirdos she encounters throughout the series — when dealing with guys who aren't trying to molest her, she is just as polite to them as she is to the girls.
    • Whenever Ataru and Mendou try to hug or kiss her, she immediately strikes them for it. On the other hand, given that this is Ataru and Mendou, there's a reason for even a straight girl to do that.
    • When Ryuunosuke first meets Ran, she initially seems very smitten with her, keeping the handkerchief Ran gives her and smelling it to remind herself of Ran's scent before asking her on a date... however, she notes to herself that her "date" is just a cover so her father won't interfere; what she really wants to do is study the kawaiiko alien in hopes of improving her own feminine ineptitude.
    • When her interactions with Shinobu are mistaken for a lover's spat, she is is livid and attacks the people who made the comparison.
    • When she is asked to go on a date with Shinobu in order to convince Shinobu's unwanted Stalker with a Crush, the delinquent boss of Butsumetsu High, to leave her alone, she agrees. However, other characters note in-universe that this is uncharacteristic of Ryuunosuke, as she hates being mistaken for a guy, and it's revealed she only agreed because the Butsumetsu High delinquents bribed her with a bra.
    • As part of her fake date with Shinobu, when the delinquents following them demand Ryuunosuke kiss Shinobu, she immediately goes to do so... whilst the only thing on her mind as she does so is the bra she was promised. When the afronted Shinobu slaps her, Ryuunosuke angrily insists that she's straight, she just wants that bra.
    • In the "Miss Tomobiki" arc, when Ran kisses Ryuunosuke to suck out her youth, the Wholesome Crossdresser is left devastated, even crying over how she was kissed by a girl. She even tries to fight to avoid being kissed by Ran again in the same arc, despite this being the fastest way to restore her youth.
    • When her father convinces the naive Ryuunosuke that eating Valentine's Day chocolate she got from one of her female admirers will physically turn her into a boy, she immediately leaps onto Ataru's plan to instead present some chocolate to a boy and tell him that she loves him when he claims that this is the "cure".
    • When Ataru tricks Ryuunosuke into wearing magnetic lipstick that will compel the user to kiss the person with the opposite polarity lipstick (It Makes Sense in Context), which turns out to be Lum, Ryuunosue is repelled and tells Lum to stop trying to kiss her.
    • After she asks Ran on a date, Mendou is told to put the moves on Ryuunosuke. When he asks her to be his girlfriend, she hits him and declares she has no interest in boys. Although later on she will insist that she's straight.
    • After meeting Benten, whose similarly macho behavior also has caused many fans to speculate about her sexuality, Ryuunosuke forms a close bond with her as a fellow warrior-woman, which some fans have interpreted as repressed attraction to her.
    • When she first learns that Nagisa, who has been aggressively trying to kiss her, is actually a really Bishōnen boy in a dress, she recoils from him and asks if he's gay. Prior to that, she was adamant that she wouldn't kiss someone that she believed to be a girl.
  • Arranged Marriage: Her dad and Nagisa's betrothed them before they were even born. Ryuunosuke despises him.
  • Berserk Button: She does not like when people mistake her for a boy or treat her like a boy.
  • Bifauxnen: So much that even girls who are aware of her gender swoon.
  • Boyish Short Hair: Almost certainly mandated by her insane sexist father.
  • Calling the Old Man Out: Several times a day.
  • Catchphrase: "I'm a chick, dammit!!!"
  • Contralto of Danger: In the anime, she has one of the deepest voices of any girl in the series.
  • Custom Uniform: Ryuunosuke wears the standard boy's outfit... at her father's insistence (the latter being in denial about not having a son).
  • Does Not Like Men: Zigzagged. When guys are treating her with respect, she can get along with them just fine, and she's normally got no problem with them. When they start getting pervy, then she hits the roof — in no small part because of her father's gender conditioning. This mainly expresses itself in a deep aversion to being touched by guys, as well as knee-jerk expressions of disgust at the idea of being with one. Unfortunately for her, she's engaged to a guy with No Sense of Personal Space.
  • Even the Girls Want Her: Yes, the female population of the school is aware that she's female and forced into Bifauxnen status by her father. They don't care — she's still hot. Subverted with Kagura and Ran; both alien girls mistake her for a boy, and lose interest once the truth comes out.
  • Hidden Buxom: Her father forces her to conceal her bust under a tight chest-wrapping bandage because he doesn't want to accept that Ryuunosuke is a girl. On the rare occasions her sarashi comes off, she's shown to be surprisingly stacked.
  • Hilariously Abusive Childhood: Her Father raising her as a boy is Played for Laughs mostly.
  • Hot-Blooded: Has a brutish temper and is prone to fighting.
  • Hypocritical Humor: Part of the comedy of her engagement to Nagisa is that she despises Nagisa for being not only as screwed up in terms of proper gender roles as she is, but actively enjoying his femininity, despite Ryuunosuke's own desire to become more feminine herself.
  • Iconic Sequel Character: She doesn't appear until the 15th volume, but since her introduction she quickly becomes a fairly prominent character, usually hanging out with the core cast and getting a lot of focus and A Day in the Limelight.
  • Jerk with a Heart of Gold: Once you get past her rough behavior, Ryuunosuke is actually one of the nicest characters in the series. She is genuinely nice to people who want to be her friends and doesn't even know what "cunningness" means.
  • Masculine Girl, Feminine Boy: She's the Masculine Girl to Nagisa's Feminine Boy. Ironically, she uses this trope as an excuse to dislike Nagisa all the more, since she wants to be normal, but Nagisa happily embraces his gender-blender nature.
  • Naïve Newcomer: She tends to be a bit clueless about things, but it's justified due to her warped upbringing.
  • Ore Onna: She uses "ore", a hyper-masculine and rather rude personal pronoun. Her catchphrase is the rather self-defeating "Ore wa onna da zo!" ("I'm a (woman/chick), dammit!"). Lampshaded and made more ridiculous by Ataru and Mendou trying to teach her to talk like a girl and showing themselves really proficient at it.
  • Raised as the Opposite Gender: Ryuunosuke's dad wanted a boy to carry on his family sea-side shop and decided to raise his only daughter as one. Ryuunosuke knows she's really a girl and wants to be more girly, but fails due to her father's meddling.
  • Real Women Don't Wear Dresses: A rather hypocritical In-Universe example towards Nagisa.
  • Sarashi: Wears one not only to demonstrate her tough combative nature, but also as a substitute for the bra her father won't let her wear.
  • She Cleans Up Nicely: In an episode where she wears the same dress as seen in My Fair Lady.
  • Tomboy Angst: She might be tough and aggressive due to her upbringing, but Ryuunosuke really just wants to be feminine. She wants to wear dresses, put on makeup and date just like normal girls do. It's difficult since her overbearing father keeps foiling her every effort to be like a woman.
  • Tomboyish Name: She has one of the most stereotypically masculine names that can exist in Japanese. To explain: As a rule, -suke is masculine, it's almost like -son (Jacobson, etc.) in English. Further, Ryu means dragon and is never a part of a girl's name (the homophone Ryu means "willow"). This is due to the fact her father is one of the most extreme examples of 'wanted a boy' in fiction - he forces her to act, talk, dress, and pretend to be a boy when she wants to be feminine… which she can't pull off because of her upbringing.
  • Tomboyish Voice: She has a voice so deep it can easily pass as a teenage boy's that hasn't broken yet.
  • Whole Costume Reference: The same dress in My Fair Lady, seen here.
  • Wholesome Crossdresser: She wears the boy's uniform. Oddly enough, she gets to wear the girls' gym uniform despite her father explicitly registering her at Tomobiki as a boy.
  • Women Are Wiser: Compared to her father, she's clearly the brains of the family. And given how unearthly Ryuunosuke can be, that's saying something.
  • Wouldn't Hit a Girl: She reveres girls so much that she'd never hit a girl.

     Kousuke Shirai 
Voiced by: Kappei Yamaguchi

Ataru's classmate and best friend.

  • Adapted Out: Never appears in the anime outside of cameos. His role was instead split amongst Lum's Stormtroopers, mostly Perm who closely resembles him.
  • Composite Character: In the anime, he was combined with a nameless member of Lum's Stormtroopers to create Perm.
  • The Generic Guy: As generic as Ataru's best friend can be, anyway.
  • Hidden Depths: Discussed in the manga's special chapter, where it's revealed that he's actually quite popular with the girls in school.
  • Satellite Character: Little is shown about shown about his characterization and he mainly appears to give Ataru someone to talk to at school.
  • Those Two Guys: Kosukes often appears with a chubby friend of Ataru who is never given a name.
  • Youthful Freckles: Unlike Perm, he has freckles.

Megane, Perm, Chibi, and Kakugari. Four schoolboys from the same class as Ataru who are in love with Lum and have sworn to protect her from Ataru.

They are as follows:

  • Megane: The bespectacled leader of the group, a manic Otaku who worships Lum and the only one to take the club seriously. The most focused of the group.
  • Perm: A tall and thin teenager with a perm hairdo. More athletic then the other stormtroopers, Perm takes the club most casually of the Stormtroopers. Perm receives the second most focus of the Stormtroopers.
  • Chibi: A short teenager with buck teeth, hence the name Chibi. A rather wimpy boy who collets models.
  • Kakugari: A large, shy teenager with a crewcut, Kakugari being Japanese for crewcut. Kakugari is a close friend of Chibi and likes wrestling. He is the least focused on of the group.

  • Ascended Extra: In the manga, they only show up for the first few chapters then leave once Mendou appears and are never given names. In the anime, however, the four are regulars, especially Megane.
  • Ax-Crazy: Megane in some episodes.
  • Back for the Finale: In the manga, they reappear for the cast spread in the final volume.
  • Bully and Wimp Pairing: Kakugari tends to roughhouse with Chibi, who oddly doesn't seem to mind.
  • Butt-Monkey: Chibi is a short, timid crybaby who is often beaten up by the rest of the Gang.
  • Childhood Friends: In the anime, its shown the four were inseparable even ten years ago. They also had a casual friendship with Ataru and Shinobu since they were kids.
  • Chuck Cunningham Syndrome: They vanish from the manga shortly after Mendou shows up. Averted in the anime where they become regulars.
  • Composite Character: Perm is a composite of Kousuke and one of the nameless members of the stormtroopers in the manga. Like the former, he is a semi athletic friend of Ataru and takes Kousuke place in most stories, and like the latter is a curly haired member of the Stormtroopers. Perm even resembles Kousuke more then the curly haired Stormtrooper.
  • Fanboys: Lum's Fan Club, as they are all obsessed with her.
  • Hopeless Suitor: Megane (and, to a lesser extent, the others), to Lum, outside of Megane, all of them realize this.
  • Hot-Blooded: Megane. In on one memorable scene from episode 64, he runs up the wall, breaks through the ceiling, and stands on the roof shouting into a megaphone.
  • Large Ham: Megane is often very loud and hammy.
  • The Leader: Megane is the leader of the Lum Stormtroopers.
  • Only Known by Their Nickname: 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 name, Satoshi, is said twice in the anime, whilst supplementary materials say Perm, Chibi's and Kakugari's real names are Koseke, Akira and Hiroyuki respectively).
  • Otaku: Megane is a caricature of a crazed, obsessed otaku taken to an extreme. The best hits are the battle armor he built for himself and the ability to identify on sight the exact variant of a tank-and operate it.
  • Scary Shiny Glasses: Megane's glasses often shine when he gets an obsession.
  • Spotlight-Stealing Squad: At times, Megane rivals the screen time of Mendo, one of the four main characters.
  • Take That, Audience!: Their obsession with Lum parodies fans of the show.
  • Too Kinky to Torture: In volume 4 of the manga, they get zapped for the first time after annoying Lum, and instead wax rhapsodic about how happy it makes them to be zapped by Lum—they're that desperate for her attention.
  • Vitriolic Best Buds: They are Childhood Friends with Ataru, but frequently fight with him. In the first episode, Megane asks Ataru to pay him back if he dies, which is given a callback in a later episode where Ataru asks Megane the same question.
  • With Friends Like These...: While technically Ataru's "friends", their interest in Lum leads them to plot against him often. Despite their antagonism towards Ataru, they often hang out with him. They're also a major cause of trouble, and in fact one could blame Lum's entire presence at Ataru's house on them.

     Class 2- 4 
The background classmates of the main cast who usually participate in the chaos.
  • Cast Full of Crazy: All of them are completely off their rocker most of the time.
  • Hormone-Addled Teenager: Whether it's the girls pining after Mendou and Ryuunosuke or the guys with Lum and Sakura, pretty much every student in the class has some sort of lustful desire.
  • Sucky School: The teachers and Principal frequently run extremely dangerous competitions and resort to ruthless tactics to keep their rowdy students in line.

Lum's infant cousin. He has a single horn on his head and can breathe fire.

  • Achilles' Heel: Ten is scared of his own mother, who is an firefighter and extremely strict towards pyromaniacs (ironically Ten can breath fire and shamelessly uses this to his advantage). He seems to be hiding this ability from her so he wouldn't get into trouble with her.
  • Adaptational Early Appearance: In the anime adaptation he's introduced in the story in the third episode. In the manga he appears much later.
  • Adorably Precocious Child: Though the "adorable" part is merely an act, he's very smart and precocious for someone still in diapers.
  • Bratty Half-Pint: He loves to act high and mighty, and puts on a façade of innocence ("I'm a good boy" is his Catchphrase), 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.
  • Breath Weapon: His fire breath.
  • Cannot Keep a Secret: Telling him a secret and the whole Class 2-4 will know it.
  • Catchphrase: "I'm a good boy!"
  • Children Are Innocent: Aside from constant fights against Ataru and not-so-innocent attraction towards women, Ten causes troubles left and right due to naïve understanding of how the world works, including the consequences of his actions, rather than out of malevolence. When encountering something strange, he usually displays curiosity and observance rather than arrogance. The downside of this is that he's so gullible that even Ataru can fool him. All in all, Ten's character embodies the feeling you have when little kids unknowingly mess with your precious stuffs.
  • The Chew Toy: Like Ataru, misfortune seems to visit Ten with considerable frequency.
  • Deadpan Snarker: Especially snarky towards Ataru.
  • Deliberately Cute Child: Whenever he's around girls — or, more noticeably, his mother — Ten tends to be much better behaved.
  • Dirty Kid: Despite being a toddler. It's played straight more in the manga than in the anime.
  • Disappeared Dad: Ten's dad was never mentioned.
  • The Fake Cutie: Because of his Deliberately Cute Child act, all the women find him adorable and are protective of him. He just uses his cuteness to get close to girls, but when he's around men he shows his true (and bratty) colors.
  • Friend to All Living Things: While he can be a brat, Ten has a soft spot for animals.
  • Iconic Sequel Character: While he doesn't appear until the 7th volume, he becomes such a prominent character in the manga that he gets an Adaptational Early Appearance in the anime, where he's introduced in the third episode.
  • Jerkass Has a Point: He may be a brat, but he's kind of right when he says that Lum deserves better than Ataru.
  • Kansai Regional Accent: He occasionally displays features of Kansai-ben.
  • Kid-anova: Flirts with every girl he sees. Howewer Ten is still essentially a child and quite naïve; around women he is usually cute and diminutive.
  • Meaningful Name: Jari sort of means "brat". So calling him by his full name Jariten is the same thing as calling him "bratty Ten".
  • Precocious Crush: He once had a crush on Sakura as well as the woman who ran the flower shop, Kurama and a few others.
  • Sitcom Arch-Nemesis: Ten and Ataru utterly despise each other. Their petty rivalry is very much Played for Laughs.
  • Spoiled Brat: He's not really spoiled by any of his caregivers, but he's definitely bratty enough to count.
  • Tagalong Kid: Obviously much younger than the rest of the cast.
  • Wise Beyond His Years: Or, at the very least, more intelligent than most toddlers tend to be.

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

  • Action Girl: She loves to fight.
  • Badass Biker: It hovers and can fly through space!
  • Biker Babe: She is the quintessential of this.
  • Celibate Heroine: It is unknown by even Lum and Oyuki whether or not she has ever had a boyfriend. However, she's seen supporting Ryuunosuke on her father issues and became excessively flustered when teased that Ryuunosuke might be in love with her.
  • Chained by Fashion: She also draps a chain over her shoulder.
  • Chainmail Bikini: Benten wears a red skimpy metal bikini, arm protector, and boots.
  • Childhood Friends: With Lum and Oyuki. They went to elementary school together and Benten is Lum's most loyal friend in the galaxy. Subverted with Ran; they know each other through Lum, but they dislike each other.
  • Contralto of Danger
  • Fashionable Asymmetry: She wears a shoulderpad on just one shoulder, simply because it makes her look cool.
  • Hot-Blooded: She is very strong willed and her mood is usually either laid back or violent.
  • Human Alien: Easily the most human-looking of the aliens — no horns, fangs, pointy ears, or shiny hair.
  • Japanese Delinquents: Downplayed. She deliberately invokes a number of "Biker Gang Girl" tropes common to Japanese manga of the time, mostly in her costume; that said, while she's tomboyish and rather ungraceful, she doesn't seem to be guilty of delinquency.
  • Jerk with a Heart of Gold: Although she can be impulsive, unpredictable, and has a really short fuse, Benten's a really good friend to have.
  • The Lad-ette: She's the most boyish and masculine-acting of Lum's circle of alien friends.
  • Meaningful Name: She is named after Shichifukujin Benzaiten (one of the Seven Lucky Gods), the Shinto goddess of knowledge, art, and beauty.
  • Red Oni, Blue Oni: The hotheaded and passionate red to Oyuki's chilly and stoic blue. She also once served as the blue to Ran's red.
  • Small Girl, Big Gun: She can uses her bazooka, machine gun and explosives to cause massive destruction.
  • Stripperific: See Chainmail Bikini.
  • Super Strength: Not as much as Shinobu, but she's shown to be quite powerful.
  • Tomboyish Voice: Which perfectly fits her attitude.
  • Town Girls: The tomboyish, bad-mouthed and violent Butch to Lum's Neither and Oyuki's Femme.

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.

  • Absolute Cleavage: For the casual swimsuit type outfit she wears when not sporting a Kimono.
  • Beware the Nice Ones: She's usually gentle and is very rare to see her angry, but Ran has very good reason to be completely traumatized by the first time she saw Oyuki get angry when they were kids.
  • Childhood Friends: With Lum and Benten. They went to elementary school together. As with Benten, she's known Ran for just as long, but she doesn't like her.
  • Deadpan Snarker: She has a great ironic wit, although it's hard to tell when she's joking.
  • Elemental Hair Colors: Icy blue hair for the ice woman.
  • Elemental Hair Composition: In the manga, her hair appears to literally be made of ice.
  • Emotionless Girl: She never shows strong emotions and remains the picture of demureness under any circumstance.
  • Hidden Depths: She's quite possibly the most powerful character in the series.
  • The High Queen: The very placid and graceful Queen of Neptune.
  • Human Alien: If not for her hair (and ice powers), one could easily mistake her as human.
  • An Ice Person: Occasionally freezing everything around her in a huge block of ice.
  • Meaningful Name: Oyuki means "honourable snow".
  • Personality Powers: As expected of An Ice Person, Oyuki is unemotional and tranquil.
  • Red Oni, Blue Oni: The chilly and stoic blue to Benten's hotheaded and passionate red.
  • The Stoic: Oyuki does have emotions like everyone else but her expression never changes much.
  • The Tease: In her intro chapter she laments at how "things were just getting started," in front of Lum after Ataru got chased away from her.
  • Town Girls: The calm, demure and feminine Femme to Lum's Neither and Benten's Butch.
  • Tranquil Fury: On the rare occasions where Oyuki does get mad, she doesn't appear to be angry on the surface, but she gets a serious look on her face as the temperature surrounding her starts to drop drastically. Suddenly, her ice powers go absolutely haywire. Ice, wind and snow rage causing unparalleled carnage and sealing any unfortunate passers-by in a block of ice or skewering them on huge icicles.
  • Winter Royal Lady: Oyuki is a Yuki-onna queen who rules over the snow planet Neptune. As for her name, Yuki means snow and the O as a prefix is an honorific character which is one way of adding a level of politeness when referring to a certain word.
  • Yamato Nadeshiko: Calm, feminine and graceful, wears a kimono, and is highly cunning and calculative.
  • Yuki-onna: She is a Trope Codifier in modern Japanese depictions of the yo-kai. Due to Oyuki's popularity, many modern depictions of yuki-onna have them with crowns on their head.

Lum's "best" childhood friend. She appears to be a sweet and lovely redhead, but in actuality has a violent, evil side. She is a succubus who has the ability to suck the vitality out of a person through kissing them on the lips.

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 madly in love with Lum's ex-boyfriend Rei (who still likes Lum, much to both girls' horror). As a result, she hates Lum and often wants to take revenge on her.

  • Beast and Beauty: She loves Rei's beast form just as much as his bishonen form.
  • Berserk Button: Stealing Rei from her. Or doing something that makes her think you're stealing Rei from her. Or screwing up her plans for a date with Rei. Or, for variety, being caught in the collateral effect of whatever Lum's up to at any given time.
  • Becoming the Mask: She desperately tries to do this with her kawaiiko persona, with rather dubious success.
  • Bitch in Sheep's Clothing: She appears to be a sweet and lovely redhead, but in actuality has a violent, evil side.
  • Butt-Monkey: The most prone of any of the female cast. As a child, she was always punished for Lum's mistakes and mideeds (even when Lum owned up to them). Plus, Rei chose Lum over her (and then Lum dumped him). And her revenge plots always fail.
  • Catchphrase: "Ran-chan is sooo happy!"
  • Chainmail Bikini: If she's not in a school uniform or a cutesy dress, she'll be wearing a silver bikini.
  • Character Development: It's subtle, but Ran gradually moves from being the closest thing the series has to a Big Bad to an occasional nuisance and Token Evil Teammate. It's shown best in "Visiting a Friend with a Cold", when she has a flashback to one of the times Lum actually stayed to care for her after her shenanigans made her cold worse, and realizes that Lum isn't actively trying to make her life hell.
  • Childhood Friends: With Lum, more or less.
  • Clingy Jealous Girl: She absolutely won't forgive anyone who "steals" Rei away from her.
  • Cloudcuckoolander: She is a bit spacey and unstable, to say the least.
  • Contralto of Danger: Ran usually speaks in a cutesy voice, but it abruptly changes to a deep gruff voice when the nastier side of her personality comes out.
  • Cute and Psycho: She is the poster child for (and likely the inspiration for all other) characters of the type, at least in anime. On the outside, she's a cute redhead who likes frilly clothing, baking, and flirting with Ataru. In reality, she's an embittered childhood rival of Lum who is out for some very violent revenge on the girl for, well, a lot of things that aren't entirely Lum's fault.
  • The Dreaded: Downplayed in that this really just applies to Lum, but as the series progresses, the oni becomes more and more likely to break out into a cold sweat when Ran is around, and especially if Ran's looking for her.
  • Easily Forgiven: Lum may get annoyed but eventually ends up always forgiving Ran despite all her revenge plots and is still hanging out with her later in the series.
  • Enemy Mine: In Movie 1, Elle learns the hard way that you do not steal a girl's boyfriend from her when said girl's rival was planning to use him to torment her. Needless to say, Ran assists Lum in rescuing Ataru from the planned shotgun wedding.
  • The Fake Cutie: Don't let her appearance fool you. She's anything but innocent.
  • Freudian Excuse: She grew up with a very strict, abusive mother. No wonder she's so messed up.
  • The Friend Nobody Likes: Downplayed. Lum genuinely likes Ran, and is willing to ignore Ran's one-sided vendetta because of that friendship. Despite the fact that they've known her just as long, neither Oyuki nor Benten likes Ran, and they make it clear that they're watching her when they interact with each other.
  • Game Face: Ran seems perfectly human most of the time... until she gets mad. Then her hair puffs out and her fangs are more pronounced.
  • Green-Eyed Monster: Towards Lum, whom she feels has "stolen" Rei from her.
  • Hair-Trigger Temper: It doesn't take much from Lum, even unintentionally (which is most of the time) to set Ran off.
  • Hilariously Abusive Childhood: When she was a child she was usually violently punished by her mother which could have traumatized Ran to develop her split personalities. This is Played for Laughs, of course.
  • Hopeless Suitor: For Rei. However, he eventually begins to cling to her, mostly because Ran keeps feeding him.
  • Human Alien: Except for the Cute Little Fangs (and red hair), she appears to be a normal human.
  • Kawaiiko: The surficial part of her personality.
  • Kiss of Death: Ran has the power to suck the youth from someone by kissing them. She tries to use the power on an unsuspecting Ataru, who had just downed a vitality elixir two minutes earlier (so the effects cancelled out), so he just assumed she likes him. She can also reverse the process with another kiss.
  • Know When to Fold 'Em: When Oyuki quietly-yet-sternly tells Ran to stop fighting, Ran immediately stands down. She's seen what Oyuki can do, after all.
  • Mad Bomber: When her Berserk Button gets hit, one of her favored methods of retaliation is to either unleash robotic dolls in her likeness that explode upon reaching their target, tossing hammer grenades, or just throw subtlety out the window and haul out a rocket launcher.
  • Meaningful Name: Ran has two meanings, both of which are suited to her warped personality. One meaning can be taken as "orchid", the other as "civil war".
  • Mood-Swinger: The two sides of her personality constantly compete for dominance. Because of that she switches from psycho-bitch to airhead and vice-versa rather suddenly and frequently.
  • Never My Fault: Even with the Freudian Excuse, a lot of the misfortune that befalls her is just karma due to her selfishness and irresponsibility. She always blames Lum, Benten and Oyuki for it.
  • Our Vampires Are Different: At least on paper: Ran's human appearance, coupled with large fangs, her succubus-like style, sexuality, and ability to literally suck the life from others are all pretty vampiric in nature, even if she's never actually called this.
  • Pet the Dog: In "My Darling's Peril", Ran's about to let Lum have it for interrupting her date with Rei... but then sees Lum weeping over Ataru's (presumed) death, and gently tries to reassure her that everything's all right.
  • The Resenter: Towards Lum.
  • Rose-Haired Sweetie: Her kawaiiko persona fits the sweet and romantic variety, but she's actually the Bitch in Sheep's Clothing variant.
  • Single-Target Sexuality: She's madly in love with Rei and no-one else.
  • Small Girl, Big Gun: When she gets ahold of Benten's missile launcher. She's later seen hauling out bazookas of her own for combat.
  • Supreme Chef: She is a superb cook and is often cooking special dishes for Rei, whom she frequently dates.
  • Third-Person Person: "Ran-chan is sooo happy!"
  • Through His Stomach: 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. It's even compared to raising a pet in the manga's omake.
  • Throw the Dog a Bone: Eventually, Rei starts hanging around her quite a bit, if only because of her good cooking. However, he's actively put her safety ahead of the food, as seen in the climax of "Lover Thief."
  • Token Evil Teammate: Out of Lum's friends, she's the only who has devious and malicious intentions to the point of often being a False Friend to the others, especially Lum.
  • Used to Be a Sweet Kid: In the flashbacks with Lum, she was an innocent, well-behaved little girl who was often punished because of Lum's irresponsible behavior.
  • Vitriolic Best Buds: By the later chapters of the manga, Ran and Lum have this dynamic. She gets triggered into psycho mode quite a bit, but she's not out for revenge as badly as she was in her introduction.
  • With Friends Like These...: Her "friendship" with Lum.
  • Yandere: Ran normally acts with a sweet façade before flipping out with her true violent and malevolent personality. This is usually, but not always to keep other girls away from Rei. Especially Lum. This is fine by Lum, who would rather Rei stay away from her, though Ran seems willfully ignorant of this dynamic.

Lum's ex-boyfriend. Rei is a very handsome Oni, to the point that most girls fall for him just by seeing his face. However, he regularly shapeshifts into an ushitora — a huge goofy-looking cross between a tiger and a bull. He speaks almost no Japanese because what little intelligence he has is channeled into eating or looking for things to eat. Lum dumped him some time before the start of the series because she tired of his stupidity, but he followed her to Earth to try and get her back. Ran is madly in love with him and plies him with her cooking in hopes of getting his affection.

  • Big Eater: He's a non-stop eating machine who is hardly ever seen not stuffing his face, or looking for eats.
  • Bishounen: Rei is a tall, stoic, green-haired space bishōnen who drives men to despair and women to squee.
  • Brainless Beauty: He can woo any human woman, regardless of her age, with his beauty, but he's also dumb as a post. It was even stated in the manga that looks are all he has going for him.
  • Catchphrase: "Lum!" and "Food!" are the main words that come out of his mouth. "Ran!" starts coming up later, though.
  • Chick Magnet: Rei breaks up loving couples just by walking past them, and causes squees whenever anything of the female gender sees him. His being dumb as a plank and loving only food does nothing to dissuade the girls... except Lum.
  • The Ditz: He's incredibly stupid, and he largely uses what little intelligence he has for eating and looking for things to eat. He's so stupid that the only reasons he's The Quiet One are because his Japanese isn't very good, and also because he can only say one word at a time.
  • Eating Contest: He actually loses one against Ataru (Rei did manage to barely out-eat Ataru in a sweet potato eating contest, but the effort caused him to lose control of his shape-shifting and collapse while Ataru was still somewhat okay).
  • Flat Character: He has not a whit of personality.
  • Hidden Depths: Despite being a Flat Character, there's hints of some complex thought in there somewhere. In the two-part story "Lover Thief", Rei's first instinct when he sees Ran falling alongside the platter of snacks she made is to save her rather than grab the food. Yes, he goes after the food next, but only when Ran's safe. Furthermore, when we get a glimpse of Rei's subconscious at the end of the anime adaptation of this story, we see multiple images of Lum... and one of Ran, sitting right next to Rei.
  • Hopeless Suitor: Lum can't stand Rei, but he still pursues her, which is honestly kind of pathetic to watch.
  • Human Alien: He looks just like a handsome, green-haired human man... unless he transforms.
  • Language Barrier: Rei doesn't speak much. Whenever he does, he is only capable of uttering one word at a time. This is mostly because Rei doesn't know how to speak Japanese, but also because he's just so incredibly, unbelievably stupid.
  • Meaningful Name: Rei means "zero". This is a good approximation of his IQ. Or his "deep" personality.
  • Not What It Looks Like: Most displays of romantic affection from him are actually his pursuit of food — one time, he kissed Ran because she had bean paste on her lips that he was trying to snag.
  • Obsessed with Food: To the point that he doesn't care about anything else other than food. Though, as we see in "Lover Thief", Ran and Lum may be equal to it in what passes for his mind.
  • The Quiet One: Not very talkative because he doesn't know how to speak Japanese. Also because, as described before, he's too dense to be eloquent.
  • Single-Target Sexuality: Lum is the only girl (or person) he has ever shown interest in, otherwise he only cares about food. He's probably too stupid to realize she hates him. Still, he hangs around Ran willingly enough, if only because she prepares a lot of delicious treats for him.
  • The Stoic: In his human form. Not so much when he gets excited and turns into a monster.
  • Through His Stomach: He reveres anyone who brings him food... or whatever can even be considered food. He dates Ran pretty much because she keeps feeding him, and Rei just learns through conditioning that Ran=food. It's been compared to keeping a pet.
  • Voluntary Shapeshifting: He can transform himself into an ushitora -– a big demonic bull-tiger hybrid –- whenever he's excited or angry.

     Princess Kurama
Voiced by: Rihoko Yoshida (JP), Daisy Talley (EN, movie 1), Stacey Jefferson (EN, BBC gag dub)

The "Crow Princess". A humanoid female from an alien race of crow tengu, her culture's laws state that she must mate with the man who awakens her from slumber with a kiss. Unfortunately for her, that person turns out to be Ataru. While she has no desire to mate with him, she initially tries to turn the perverted lech into someone worthy of her... but gave up once it became obvious that reforming him is impossible, and subsequently runs in the opposite direction whenever he shows up. She has the ability to create powerful gusts of wind with her multi-use giant leaf.

  • Absolute Cleavage: Her bodice (and later, leotard) leaves little to the imagination.
  • Bizarre Sexual Dimorphism: Males of her people look like bipedal crows that are a few inches tall and have beards when they're older. Kurama (and at least other royal females such as her mentioned but unshown mother) look nearly identical to human women.
  • Blow You Away: She has the ability to create powerful gusts of wind with her multi-use giant leaf.
  • Combat Hand Fan: Her weapon is a giant leaf that she uses as a hand fan.
  • Daddy's Girl: She really loves her dad Minamoto no Yoshitsune and holds him as the standard for a man. She even takes Ataru into the past, so he can learn a thing or two from her dad. Instead Ataru tries to corrupt Minamoto.
  • Dude, She's Like, in a Coma!: She was going through with a tradition where she put herself in suspended animation till a prospective mate woke her up by kissing her.
  • Half-Human Hybrid: Her mother was an alien tengu, while her father was Minamoto no Yoshitsune, a famous Japanese warrior.
  • Human Alien: The only alien traits are the little crow wings on her head.
  • I Can Change My Beloved: She tries to reform Ataru — indeed, she puts a great deal of effort into it, while fighting off both Lum and Shinobu — but eventually gives up once she realizes that Ataru's set in his ways.
  • Jerkass: She's usually a mean person towards others; particularly if they try to interfere with her attempts to land a worthy man. This includes Ran, who was dating Rei when Kurama tried to seduce him.
  • Looking for Love in All the Wrong Places: Every potential mate is a failure. Ataru is a pervert, Mendo turns out to be too pathetic and cowardly, Ryuunosuke isn't really a man like she thought, and Rei seems like the one until she sees he is really an idiotic tiger-cow.
  • Ms. Fanservice: Wears a skimpy outfit, has several bath scenes and in one occasion her breasts are visible when one of her tengu remove her bodice.
  • Pet the Dog: When Ten got caught up in her vortex, she was quick to scoop him up and cradle him gently until he regained consciousness. She was also quite patient when he tried to hit on her, compared to her treatment of the similarly presumptuous Ataru.
  • Really 700 Years Old: She has a youthful appearance, but her father was Minamoto no Yoshitsune, a famous warrior and one of Japan's greatest heroes, who lived in the 12th century.
  • Rich Bitch: A princess with a rude and unpleasant attitude. The only reason she even tried to reform Ataru in the first place (aside from her culture's law) is because Lum dragged him away from their first meeting, prompting this:
    Kurama: What is it about other people's things that makes me want them?
  • Stripperiffic: Kurama has an outfit well established in all the episodes in which he appears, composed of a bodice black / blue laced on the breasts with a yellow bow, boots, several bracelets and a black collar. In the manga, she later swaps it out for a leotard with an Impossibly-Low Neckline.
  • Tengu: She is a Cute Monster Girl version of the Tengu (though she trades the long nose for little crow wings on her head and is thusly Bird People). She's also served by more traditional Karasu Tengu (which are runty little humanoid crows).
  • Weaksauce Weakness: As a side-effect of spending so long in cryo-sleep, she gets sleepy whenever she's cold.

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

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.

  • Big Eater: Lum's father.
  • Big Ol' Eyebrows: Lum's father.
  • Fat Bastard: A downplayed case with Lum's father. He's normally a bit closer to Big Fun, but one time, he ate his wife's meal after he finished his. Then when his wife kicks him out, he demands that she apologize. Thankfully, said wife is quick to put him in his place.
  • Gonk: Lum's father, only a few one panel Joke Oni have been as monstrous as him.
  • Huge Guy, Tiny Girl: Lum's dad towers over most of the cast, while her mother is much closer in height to them.
  • I Was Quite the Looker: Lums's father used to be a decent looking fellow revealed in a flashback. He gained A LOT of weight because his wife stuffed him up with her cooking.
  • Starfish Language: Lum's mother does not speak any Earth language, with strange characters and symbols being used in the manga whenever she's speaking.
  • Strong Family Resemblance: Lum's mother, who strongly resembles her daughter except with her hair cut short.
  • Ugly Guy, Hot Wife: Lum's father is stout and rather brutish-looking. Her mother... considerably less so.
  • Unnamed Parents: We don't get a name for either of them.

     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.

She is based on the firemen of Edo Japan.

  • Blood Knight: She enjoys fighting fires and arsonists with equal gusto.
  • Catchphrase: "FIRE!!"
  • In Harm's Way: It's implied that she feels the most comfortable when fighting fires — the bigger, the better.
  • Oblivious Guilt Slinging: Her gung-ho attitude towards punishing people who set fires leaves Ten terrified. She doesn't seem to be aware of his fire-breathing tendencies around Ataru.
  • Parents as People: While she usually left Ten in the care of a robotic nanny, she regrets not being able to spend more time with her son.
  • Unnamed Parent: Like Lum's mother and father (and Ataru's), we never get a name for her.
  • Workaholic: She constantly carries around her firefighting equipment.

     The Spice Girl Gang
Voiced by: TARAKO (Sugar), Chika Sakamoto (Ginger), Rumiko Ukai (Pepper)

Sugar, Ginger and 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.

  • Adaptation Dye-Job: In the manga, Sugar's hair is pink note  and Ginger's hair is black. In the anime their hair colors were changed to black and blonde respectively, however in the 2010 OVA, Sugar's hair is back to being pink while Ginger's hair is still blonde.
  • Big Bad Wannabe: They want to be a feared trio of delinquents, and frequently menace Lum and her friends to pull it off. Unfortunately for them, their complete incompetence prevents them from being any real threat.
  • Butt-Monkey: None of their schemes really work out, often with humiliating results. Being thoughtless jerks with a high opinion of themselves, they tend to have it coming. They even failed to seduce Ataru.
  • Cat Girl: Ginger.
  • Chameleon Camouflage: Sugar's special ability allows her to blend in with her surroundings. While this would be useful for sneak attacks, Sugar's habit of announcing the technique as she's using it makes it easy to track her down.
  • Dark-Skinned Blonde: Ginger in the anime, especially in the 2008 OVA.
  • The Dividual: The three of them are often seen together, causing trouble for Lum and her friends.
  • Edible Theme Naming: All three of them are named after spice-related condiments.
  • Faking the Dead: Ginger is able to slow down her bodily functions to the point that an untrained observer will believe that she is dead.
  • Giving Them the Strip: Pepper's power is a full-body example of this, where she sheds her skin like a snake to escape being grabbed.
  • Goldfish Poop Gang: These three lack the sense, power, or competence to be any real threat most of the time.
  • Human Aliens
  • Magic Pants: Pepper, who can shed her skin at will. This includes a replica of her clothing, leaving Pepper fully clothed.
  • Not-So-Harmless Villain: In their last appearance, they try using animal minions to even the score with Lum and company. Their first attempts with Benten and Oyuki fail miserably... and then they bring out a giant electric eel to use against Lum, leaving her lightning powers useless. They only fail because their attacks on Lum keep hitting the eel too, ticking it off to the point where it pulls a Heel–Face Turn to help Lum.
  • Small Name, Big Ego: They give big speeches about how they're superior to Lum, Benten, and Oyuki. They... really ...aren't.
  • "Super Sentai" Stance: Did this at least once in the anime, ironic since none of these girls are heroic.
  • Terrible Trio: An especially inept example. Sugar tends to be the leader, but they're all equally dumb. They consider Lum, Benten and Oyuki their rivals, but are ignored by them.
  • What Kind of Lame Power Is Heart, Anyway?: While Chameleon Camouflage, Faking the Dead, and Giving Them the Strip are powers that could be useful in the hands of skilled people, Sugar, Ginger, and Pepper are not bright enough to use them to their best effect. Plus their opponents are usually Lum, Benten, and Oyuki, who are flat-out leagues above them.

     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.

  • Big Bad: Of the first movie.
  • Bond Villain Stupidity: If she had just remained focused on Ataru instead of falling for one of those trying to rescue him, Ataru would likely have never found out about her frozen harem.
  • Chainmail Bikini: Her outfit consists of a rose-red one-piece "swimsuit" beneath a regal white cape.
  • Childhood Marriage Promise: She wants to marry Ataru even if by force because they played a game of shadow tag and on her planet stepping on someone's shadow is considered a marriage proposal. At the end it turns out Ataru never stepped in her shadow in the first place and therefore their engagement is null.
  • The Collector: She collects all of the handsome men that have ever loved her and freezes them for storage inside a giant refrigerator, to "keep their love forever fresh". She plans to make Mendou the 100,000th (and last, as the next day she'd marry Ataru and settle down).
  • Dude Magnet: She's attracted a considerable number of suitors by the time she shows up.
  • Forgotten Friend, New Foe: She met Ataru when they were both little kids, but Ataru forgot all about her until she shows up during the movie.
  • God Save Us from the Queen!: Downplayed example—she's a beloved ruler on her homeworld, but she's rather obstinate and determined to have her way no matter what.
  • Villain Ball: She just had to try and freeze Mendou, didn't she?
  • World's Most Beautiful Woman: Not just of her own planet, but of the entire universe. 99,999 men prior to Ataru certainly thought so.
  • Yandere: Towards Ataru—when he tries to call the wedding off, she will not take no for an answer.

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.

  • And Now You Must Marry Me: He kidnaps Lum and tries to force her to carry out their Arranged Marriage.

  • Arranged Marriage: It was arranged by Rupa's great-grandfather that he would marry Lum.
  • Being Evil Sucks: He ends up admitting to Carla that his blind adherence to his grandfather's wishes in trying to marry Lum caused more trouble than it was worth, and that it made it harder for him to admit to himself who he really loves.
  • Big Bad Wannabe: He triggers the start of the final arc with his engagement to Lum. Ultimately, however, the final conflict boils down to Lum and Ataru's mutual stubbornness, and Rupa finds himself sidelined.

  • Never My Fault: He thinks Carla's behavior is unreasonable, ignoring that she does have a legitimate grievance against him.
  • Stupid Evil: While his schemes actually do manage to work to some extent, he fails at being imposing. In his entrance scene, he crashed into a wall and had to be brought into the infirmary to recuperate.
  • Tohoku Regional Accent: For some reason, he speaks with a Tohoku accent, given the nature of the series this could just be Rule of Funny.
  • Unknowingly in Love: Since he was told that he would marry Lum from a young age, he couldn't understand he didn't want that or that he wanted to marry Carla all along, until the penultimate chapter.

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 arch-enemy.

  • Chainmail Bikini: Like many of the other girls in the series, she favors this.
  • Childhood Friend Romance: With Rupa. Near the end of the movie, Rupa admits that he doesn't really want to marry Lum and asks Carla to marry him.
  • Clingy Jealous Girl: Ever since Rupa told her about his engagement to Lum, she has constantly threatened and terrorized Rupa out of jealousy.

  • Murder the Hypotenuse: She was killing to kill Lum to prevent Rupa from marrying her, either unaware or not caring that Lum wasn't on board with this engagement.
  • Small Girl, Big Gun: The weapons she hauls out tend to be as long as she is tall.
  • Stalker with a Crush: She's in love with Rupa, and did not take it well when he told her he was engaged to Lum.
  • Tohoku Regional Accent: Much like Rupa, she also speaks with a Tohoku accent and it fits with her overall personality.
  • White Hair, Black Heart: She's a possessive and murderous Yandere with white hair.
  • Yandere: She did NOT take Rupa's engagement to Lum well. Since then, she has spent most of her life chasing him and trying to kill him.

Citizens of Tomobiki

    Ataru's parents
Ataru's father is voiced by: Kenichi Ogata (JP), Marc Matney (EN, test dub), Alan Marsh (EN, BBC gag dub), Jerry Winsett (EN, movies 1, 3-6), Larry Robinson (EN, movie 2), Darren Pleavin (EN, Animax)
Ataru's mother is voiced by: Natsumi Sakuma (JP), Dorothy Rankin (EN, test dub), Stacey Jefferson (EN, BBC gag dub), Belinda Keller (EN, movies 1, 3-6), Jackie Tantillo (EN, movie 2), Andrea Kwan (EN, Animax)

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.

  • Abusive Parents: Ataru's mother is the verbally/emotionally abusive type. She's constantly going "I wish I never had him."
  • Adults Are Useless: Ataru's father just sits reading his newspaper hoping the insanity will stop.
  • Aw, Look! They Really Do Love Each Other: Despite their verbal abuse, both parents are genuinely upset when they think Ataru has died in an early chapter, with the mother even bursting into tears. The father cries out that Ataru may have been a fool, but he was their fool.
  • Butt-Monkey: Quiet, timid, and possessing very little dignity, Ataru's father tries his best to hide his face behind the newspaper during bad situations, often wishing he'd be treated better since he's the sole provider for the family.
  • Catchphrase Insult: Ataru's mother usually says "We never should have had him!" about Ataru. Sometimes she even tells him to his face. Thankfully it becomes an Abandoned Catchphrase in later chapters.
  • Housewife: Ataru's mother.
  • Mrs. Robinson: Ataru's mother has a crush on Rei, to her husband's despair.
  • No Accounting for Taste: Together they have an annoyingly common domestic relationship that is either dull as dirt, or on the rocks.
  • No Sympathy: 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.
  • Perpetual Poverty:
    • Ataru's parents are always struggling to make ends meet, even though Ataru's "wife" is a princess from a highly advanced alien planet (at one point, she casually pays an intergalactic taxi fare which amounts to the value of all the oil on planet Earth).
    • Ataru's dad regularly worries about how many more payments he needs to make on the house. Not once does the word "foreclosure" ever come up, and at the end of the series he and his family still have their home (despite it being completely destroyed several times).
  • Salaryman: Ataru's dad works long hours and worries about the mortgage, especially since his house is routinely destroyed.
  • Unnamed Parents: Their names are never revealed.
  • Wanted a Son Instead: There's 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.

     Sakurambou (Cherry)
Voiced by: Ichirō Nagai (JP, original series), Wataru Takagi (JP, All-Stars), Eric Paisley (EN, test dub + movies 1, 3-6), Larry Robinson (EN, movie 2)

A wandering monk. Cherry has amazing spiritual powers (or so he claims) and he often predicts doom for Ataru. A notorious glutton and moocher, nobody likes Cherry, but he keeps popping up despite being unwanted.

  • Big Eater: His vow apparently doesn't apply to food, as he is exceedingly gluttonous, and often offers his services in exchange for a free meal (or simply blatantly eating other's food despite not planning to help with anything, often eating everything before anyone else can have any).
  • Catchphrase: "'Tis fate."
  • The Friend Nobody Likes: He frequently tags along with the main group and everyone is always annoyed by his presence.
  • Gonk: Played horribly straight for those who have to endure his close-ups.
  • The Jinx: "If you're with Cherry, you can get run over crossing the road on a green!"
  • Meaningful Name: His name Sakurambo is the Japanese word for "cherry", as he likes to be called. But in another sense it can also mean "deranged priest", which is an accurate depiction of him.
  • Miniature Senior Citizens: He's only about two feet tall.
  • Sitcom Arch-Nemesis: For reasons known only to the annoying monk himself, Cherry constantly interferes in Ataru's life and gives him grief for his corrupt personality, base desires and bad luck. He has taken a vested interest in seeing through his downfall. That said, he actually never showed any kind of malice and usually attempts to help the characters he came across (and actually did on very rare occasions). It's just that his attempts to help usually cause even more trouble.
  • Verbal Tic: Cherry ends most of his with "-ja", which is pretty stereotypical of old men in Japan.


Voiced by: Machiko Washio (JP, original series), Miyuki Sawashiro (JP, All-Stars), Karen McIntyre (EN, movies 3-6)

Cherry's niece. She was once a very sickly girl who suffered from a variety of ailments due to being infested with a plague of malevolent spirits. After meeting Ataru for 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.

  • Absolute Cleavage: Her purple outfit that she wears in the early seasons.
  • Aloof Dark-Haired Girl: She's very tall and beautiful, has long black hair and pale skin and possess a graceful and aloof attitude.
  • Beauty Is Never Tarnished: Despite her gluttonous appetite, Sakura remains incredibly beautiful, and never even succumbs to so much as a Balloon Belly, even when winning a Mega Meal Challenge! The closest that she comes to subverting this trope is when she tries to rest on a floating recliner after the aforementioned Mega Meal Challenge, only for it to sink under her newly increased yet invisible weight.
  • Berserk Button:
    • Lecherous boys feigning sickness or even deliberately hurting themselves in order to have an excuse to check her out. She reacts by violently pummeling the fools who she catches out doing this.
    • Dismissing her spiritual powers and refusing her offers to exorcise people also affront her.
    • Whilst she is the one person who truly respects Cherry, even she doesn't like him very much, and she gets particularly angry when she sees him mooching.
  • Big Eater: Of the "impossibly slender" variety. She's actually the biggest eater in the cast (except maybe Rei), but her figure never changes no matter how much she eats. To put things in perspective, in the manga's 5th volume, she partakes in a Mega Meal Challenge, in which she consumes, in order: a plate of spaghetti, a 300g steak with buttered rice, rare bonito with fresh-cooked rice, a whole roast chicken, five-treasures fried noodles, a wild duck stuffed with vegetables, a cake, a roast leg of lamb, a whole roast turkey, a whole pig, and finally a whole roast COW! And not only are these just the dishes shown on-page, of a meal that contains over 15 courses, but she ate all of this after consuming two "Mannon Rise" diet pills, just one of which magnifies the stomach's perception of its fullness by 300 percent. And she was still peckish afterwards! A short essay on Sakura at the end of the first 2-in-1 English manga even notes that Sakura must have an exorbitant food bill to pay for such a monstrous appetite.
    • During the Tomobiki Beauty Contest arc, when it reaches the Eating Contest phase, she muses to herself how embarrassing it would be to actually win and so decides to only eat until she's "moderately full". Even as she's thinking that, she polishes off a whopping fifty-eight bowls of ramen, leaving her the clear winner, whilst the best Lum and Ryuunosuke manage is four apiece.
  • Charles Atlas Superpower: Like Shinobu, she is capable of feats of Super Strength when she is angry.
  • Cherry Blossom Girl: Her name is Sakura and is related to healing due to being a Miko and a nurse.
  • Contralto of Danger: Has the deepest voice amongst the female cast, and is quite dangerous herself.
  • Cool Big Sis: To Lum and Shinobu.
  • Dude Magnet: Besides her fiance Tsubame, she is the object of affection for pretty much every male at Tomobiki High. Ten also developed romantic feelings for her, but she treats him in a motherly manner.
  • Head-Turning Beauty: Regular reaction of every male to her, especially Ataru (once he gets over his fear of her). When she arrives at Tomobiki High practically every male student gathers outside the gates to greet her in this way.
  • Hospital Hottie: She's the resident nurse at Tomobiki, and she's also incredibly gorgeous, to the extent that many boys will actually willingly get sick or hurt as an excuse to see her. Unfortunately for them, that's one of her Berserk Buttons.
  • Hypocrite: She repeatedly chides Cherry as a glutton and a mooch, but she herself is shown mooching food on more than one occasion.
  • Ill Girl: She was "born with a weak constitution" and suffered from spontaneous illness for most of her life. Her uncle deduced that this was a side-effect of her spiritual powers, which made her a magnet for evil spirits and disease kami—unfortunately, by the time she developed her powers to the point she could cast them out, they had too firmly entrenched themselves, allowing them to disrupt her efforts at self-exorcism. At her uncle Cherry's suggestion, she set out to meet Ataru Moroboshi, whom she offered an exorcism for his bad luck. As Cherry had predicted (although it's unclear if Sakura was in on it), the bad spirits infesting her were drawn to Ataru, freeing her of her diseases and allowing her to both banish them and ward herself against future ailments.
  • Lust Object: For much of the male contingent of Tomobiki High School with Ataru being the first of all.
  • Meaningful Name: Sakura means "cherry blossoms".
  • Mega Meal Challenge: She absolutely loves these as each time she does 'em it's a Curb-Stomp Battle in her favour. In the Hell Course challenge at a beach hotel banquet, she continues long past Cherry and Ataru's losses and ends up eating the hotel out of everything except some dessert (a feat that no one has done before, and this after she had an appetite suppressant pill). For her these events are just an opportunity for free food.
  • Miko: She's actually a full-on priestess with strong spiritual power. She and Cherry are seen many times throughout the series trying to exorcise evil spirits.
  • Ms. Fanservice: She is gorgeous and the most buxom character in the series. No surprise that she is subject to Male Gaze many times.
  • Only One Name: Her full name is unknown, as she is only ever referred to as "Sakura".
  • Only Sane Woman: Compared to the other characters, she's actually very calm (especially when Ataru is not around), wise, and mature.
  • School Nurse: She joins the Tomobiki High School staff as the school nurse.
  • Sexy Walk: Sakura's first day as the school nurse has what looks like the entire student body on the front lawn to watch her walk in... which makes Ataru's reaction all the more interesting.
  • So Beautiful, It's a Curse: Especially if boys like Ataru chase you.
  • Statuesque Stunner: Her height is never stated, but she is one of the tallest (human) characters in the series. And once she's cured of her diseases, it becomes obvious just how beautiful she is.
  • The Ugly Guy's Hot Daughter: Her mother looks like Cherry with a wig, while Sakura is a bombshell.

     Tsubame Ozuno 
Voiced by: Kazuhiko Inoue (JP), Sean P. O'Connell (EN, test dub), Eric Meyers (EN, BBC gag dub)

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.

  • The Ditz: He is indecisive, foolish, and slow witted.
  • Engagement Challenge: He is introduced trying to impress Cherry with his magic so that the old man will approve of Tsubame's engagement to Sakura.
  • Ethnic Magician: Tsubame is a wizard who practised black magic in the west. As a result his magic has a distinctly North American and European flair. In particular, his Summon Magic calls forth creatures from Western pop culture, such as vampires and Frankenstein's Monsters.
  • Inept Mage: He is not very good with the magic.
  • Magicians Are Wizards: The way he executes his skills make him seem more like a performing magician than a wizard.
  • Meaningful Name: Tsubame is the Japanese word for "swallow" (bird). Ozuno means "from Oz".
  • Only Six Faces: Looks like a taller Godai.

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.

  • Badass Adorable: He is a cute giant human-cat, but also very strong. The only character stronger than him is likely Oyuki.
  • Gentle Giant: Despite his monolithic size (for a cat), Kotatsu-Neko is nonetheless one of the most demure and zen-like denizens of the series' universe.
  • Mega Neko: He's a human-sized cat.
  • Mighty Glacier: Arguably qualifies as the series' main example, owing to his simultaneous potent physical strength and demure, leisurely natural demeanour.
  • Odd Friendship: He gets along well with Cherry and Ten, but he seems to be closest to the Tomobiki High School Principal, whom he is often seen drinking tea with.
  • Our Ghosts Are Different: He is a giant ghost cat who is fully corporeal.
  • Super Strength: He's the strongest character in the series, easily capable of overpowering Benten (another character with Super Strength) and defeating Kenshiro in five seconds flat.

     Ryoko Mendou
Voiced by: Mami Koyama (JP), Michele Seidman (EN, movie 3), Toni Barry (EN, BBC gag dub)

Shuutaro'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.

  • All Girls Like Ponies: Not really in her case, but she does love to show off by riding her "horse" which is just a pair of Kuroko dressed as a horse.
  • Annoying Younger Sibling: She finds the greatest pleasure in tormenting her brother which is a full time occupation of hers. She knows how overprotective her brother is of her and she likes to use it against him. She'll concoct intricate plots that serve to ultimately infuriate, humiliate, or even kill him. She'll even flirt with Ataru just to see her brother fly off the handle.
  • Bitch in Sheep's Clothing: She acts like a cute and innocent girl, but she'll try and harm you… and then act like nothing happened.
  • Catchphrase: She frequently states "I hold no grudges" as she is leaving a trail of grenades behind her.
  • Clingy Jealous Girl: Ryoko is one girl you don't want to make jealous, the recipient is almost always her brother such as when she got annoyed about his Perfectly Arranged Marriage with Asuka.
  • Decoy Damsel: Likes pretending to be in danger only to attack her rescuers.
  • Devil in Plain Sight: No one but Tobimaro and Mendo realizes her manipulative and cruel nature.
  • Drama Queen:
    • She makes everything happens around her looks like a fateful challenge. Bringing boxed lunch to brother? Sit in an ox-cart and journey the town for who whole days. Want to hang out with some boys? Make sure to pick the ones that annoy her brother the most so that it'll be a Star-Crossed Lovers story. Said brother has an Arranged Marriage? It means he has cruelly spurned the devotion of his poor, poor sister. The list goes on.
    • Near literal, as she is always escorted by a bunch of kuroko, traditional Japanese stagehands. It reinforces the idea that Ryoko views the world as a big stage play.
  • Dude Magnet: Similar to her brother being a Chick Magnet. When they made a contest at her house, they said the winner will get a kiss from Ryoko and all the guys are very excited by the idea (including Ataru, obviously).
  • Elite Army: Normally the Mooks of the Mendou security forces are a bunch of brain-dead morons. However Ryouko has her Kuroko, these ninja stage hands are extremely skilled and cunning combatants that are loyal only to her. They've even taken down Lum who's normally a walking Mook Horror Show.
  • Faux Affably Evil: The way she acts is almost charming, and it's easy to forget that she's really a devious and twisted Manipulative Bitch.
  • Hime Cut: Her hairstyle to indicate her position as a high-class lady.
  • In the Blood: Her personality includes aspects from both her mother and father. Like her dad, she loves mean-spirited dangerous pranks and from her mom she loves old-fashioned things (though she does like her modern gadgets and firepower).
  • It Amused Me: Played for Laughs. She enjoys tormenting her brother Mendou and the rest of the shows cast whenever she's bored.
  • Karma Houdini: Never pays for her actions.
  • Lack of Empathy: Views other people as her playthings.
  • Loving Bully: An ambiguous case. She has been pranking and tormenting Tobimaro since childhood and also claims to be in love with him. It's not clear if she's serious about her "love" for him, given her sadistic tendencies. If she is, this is still quite disturbing.
  • Manipulative Bitch: She certainly appears to be a sweet girl. But underneath this veil of innocence lurks a twisted mastermind.
  • Noblewoman's Laugh: A more subdued version.
  • Ojou: She acts like a lovely, demure and well-mannered girl.
  • Rich Bitch: A spoiled rich girl who enjoys being cruel to others.
  • Royal Brat: Ryouko has a legion of servants, and dresses in kimonos and Victorian dresses while dutifully pulling out grenades and voodoo dolls or putting on a Wounded Gazelle Gambit to mess with her brother and his friends, all while conveying that she never holds grudges.
  • Sadist: She uses underhanded mischief and devilish practical jokes as a primary source of pleasure.
  • The Sociopath: She requires little to no provocation to mess with her brother or anyone else, all the while bemoaning how she had "done all she could" to help her dear older brother.
  • Spoiled Brat: Like Mendou, but she's less pompous and more sadistic.
  • Star-Crossed Lovers: Invoked mercilessly upon Tobimaro, as Ryouko claims they are seeing each other against the wishes of their feuding families. Ultimately suberted, as once she gets the chance to "elope" with a tied up Tobimaru, the first thing she does is to put him a trash can in a seedy back alley.
  • Troll: Growing up, always getting her way, and having every luxury a girl could want meant Ryoko became bored easily. But she found that causing trouble and watching people squirm was the best form of entertainment.
  • Yamato Nadeshiko: A tradition-oriented and elegant lady, completely devoted to her brother and later her (forbidden) love. It's a pity that those around her "just happen" to end up in disasters.

     Mendou'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.

  • Amazingly Embarrassing Parents. For one example, Mrs. Mendo travels exclusively by ox cart. Cars are too "novel" for her.
  • Good Old Ways: Mrs. Mendo is very old fashioned and is a firm believer in Older Is Better. Her hair and clothing look like something from the Edwardian era (but without the hat). When playing with a Ryouko who was 4-5, she entertained her daughter by doing a hand-held puppet show set.
  • Mistaken for Gay: When Mendou's mother challenged Lum's mother to a duel, Lum's mom thought the thrown glove was a marriage proposal.
  • Strong Family Resemblance: Before art evolution, Mendou's father was his son with a mustache.
  • Troll: Like father, like daughter.
  • Unnamed Parents: Neither one of them is ever referred to as anything other than (Mendou's) mother or father.

     Tobimaro Mizunokoji 
Voiced by: Bin Shimada (JP), Scott Whiteside (EN, movie 4), David Jarvis (EN, BBC gag dub)

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.

  • Barbarian Long Hair: His hair is long to show he's lived in the wilderness.
  • Big Brother Instinct: He comes to care deeply and become protective of his sister Asuka.
  • Bodyguard Babes: He's often flanked by a squad of lovely female bodyguards.
  • Butt-Monkey: Animals Hate Him, his Training from Hell was worthless, he sucks at baseball, his sister is always accidentally injuring him, his mom thinks he’s a screw up, and his rival's sister dedicates her time to torturing him which everyone blames him for.
  • Exotic Eye Designs: His eyes have star-shaped pupils, a parody of a popular sports manga motif at the time.
  • Extreme Omnivore: He can eat baseballs and ceramic plates and bowls. In fact, baseballs are something of his Trademark Favorite Food, as a side-effect of his bungled Training from Hell; he instinctively tries to catch and eat any baseball thrown around him.
  • He-Man Woman Hater: Ton-chan has a certain mistrust and dislike of women, which stems from his childhood with his rival's sadistic sister Ryoko.
  • Hilariously Abusive Childhood: All thanks to Ryoko.
  • Hot-Blooded: Complete with Hot Blooded Sideburns even.
  • Meaningful Name: Mizunokuji is a play on the real-life Mizuno sporting goods company which is known best for their baseball equipment.
  • Noble Bigot: Despite his dislike of women, he tries to be a good brother to Asuka, is respectful to his mom, and doesn't abuse his female underlings.
  • Nosebleed: Seeing his lovely kid sister naked caused him to lose 1/3 of his blood supply out of his nose.
  • No Sympathy: No one gives him any sympathy or aid about his torture at Ryoko's hand. The Guys, especially Mendo, beat him up for seducing Ryoko; the girls think it's romantic.
  • Only Sane Man: Tends to be only person to be fully aware of Ryoko's evil nature, and that her love for him is just her preferred method of torturing him.
  • The Rival: He is Shuutaro Mendou's baseball playing, starry-eyed, childhood rival. Of course, he's actually terrible at baseball.
  • Tragic Bigot: He can't stand women because of a lifetime of torture at Ryoko's hands.
  • Training from Hell: Subverted, his time in the wilderness only gave him the ability to eat baseballs, because he was too inept to forage for himself and so the only thing he had to eat were baseballs.

     Asuka Mizunokoji 
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.

  • 24-Hour Armor: Asuka likes to wear a tank-like suit of armor because it makes her feel safe.
  • Always Someone Better: As mighty as Asuka is, she's puny compared to her mom who easily beats her and chains her to Ataru.
  • And Call Him "George"!: Being loved by Asuka is perhaps more dangerous than scaring her, because one hug from her can crush a man's spine.
  • Arranged Marriage: With Mendou.
  • Beautiful All Along: Asuka doesn't look very attractive at first because of the bulky suit of armor she's wearing at the time. 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. Also 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...
  • Catchphrase: "EEEEK! A MAN!!"
  • Comically Missing the Point: In one story arc involving Asuka, Lum leads her to a tank so she can leave the premises without any men getting too close to her. Asuka thanks Lums, saying it's exactly what she needs...before tearing the tank apart bare-handed and bending the ensuing scrap metal into a makeshift suit of body armor.
  • Does Not Like Men: Being kept isolated from men according to family tradition, with bungled explanations as to what men are, combined with her first exposure to a man being the Lovable Sex Maniac Ataru Moroboshi, means that Asuka is absolutely terrified of men. As in, she starts screaming when she sees one, before trying to throw things at (or beat up) the unlucky man who caught her eye. Unfortunately, she also inherited her mother's super-strength, so she can cause tremendous pain to any man whom she attacks. Of course, that's the lesser evil, as her brother Tobimaro can testify: being classified as a "big brother" (which to her means "a special kind of man who's just like you", and is the one exception to her "men are scary!" mentality), combined with the fact that Asuka developed a crush on him, means rib-crushing, literally-back-breaking hugs.
  • Exotic Eye Designs: Her eyes have star-shaped pupils, like her brother and mother.
  • The Ingenue: She was completely sheltered for the first 16 years of her life.
  • Lovable Coward: Yup even she admits how gutless she is, but she's such a sweetie that most people she encounter just feel protective towards her and convince themselves it's merely timidness and outgrowth of her phobia of men. And she does occasionally get a moment where she gets the backbone to talk back to her mother.
  • Megaton Punch: In this case, it's a hard shove but the effect still means normal people achieve a long flight time.
  • No Social Skills: Being kept in absolute isolation with a bunch of well-meaning but bungling maid-servants all her life means that what Asuka knows about interacting with the real world would probably fit on a handcard.
  • Perfectly Arranged Marriage: She warms up to the idea of marrying Mendou after she finds out he's a "big brother" like Tobimaro.
  • Sheltered Aristocrat: She was kept isolated from the outside world her entire life to avoid contact with any and all males, according to the Mizonokuji family's tradition. As a result, she's very naive and develops an extreme fear of men because of Ataru.
  • Shrinking Violet: Due to being brought up in total isolation from humanity, Asuka is extremely shy and timid. If she weren't super-strong, she wouldn't be anywhere near as dangerous as she is.
  • Super Strength: With the exception of her mother and possibly Shinobu, she's the single strongest character in the series physically.

     Tobimaro'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... which she basically caused. She is even more powerful than Asuka, and has the power to do the "angry big-head" technique.

  • Beware the Nice Ones: The mother seems like a nice enough woman, but she's a lunatic in her own right, has Super Strength, and isn't afraid to express her feelings violently.
  • Demon Head: The mother's "Angry Big-Head" Technique, which she uses frequently enough that it almost feels like a Call-Forward to Soun Tendo of Ranma ½
  • Exotic Eye Designs: The mother has star-shaped pupils in her eyes.
  • Frozen Face: The mother's facial expression never changes from a slight smile, no matter what she's thinking or how she's feeling.
  • Has a Type: The mother likes her men Gonk, when she sees Ryuunosuke Fujinami for the first time she mentions that while the "boy" has a very manly presence, he's not very handsome and then a comic panel shows what she considers handsome.
  • Henohenomoheji: The father is presented this way.
  • Lineage Comes from the Father: Inverted. Unlike the Mendous, the Mizunokuji current line extends from the mother. The father married into it and is unfamiliar with all the Mizunokuji customs such as him not allowed to see his daughter until she's 15. Mrs. Mizunokuji being the lineage holder is also why she and the kids have the star-shaped pupils.
  • Ugly Guy, Hot Wife: Mrs. Mizunokuji is presented as a gorgeous woman. Mr. Mizunokuji... well, his face is literally made up of a bunch of kanji scribbles.
  • Unnamed Parents: As with pretty much every parent in the series, the Mizunokujis are never addressed by personal names.

     Mr. Fujinami 
Voiced by: Masahiro Anzai (JP), Toru Okawa (JP, OVA 12), Langley McArol (EN, movies)

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. 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.

  • Abusive Dad: He fulfills at least several of the types of abuse in regards to his daughter Ryuunosuke. Apparently solely because of his insane levels of chauvinism, he is convinced that a "mere" girl is unable to run his precious (run down) tea shop, and so he has forcibly raised her as a boy, despite her protests, since her mother Masako died left him. He refuses to allow her to buy any feminine clothes, both by refusing to give her money to do so and stealing/destroying any she does manage to get, demands she speak in masculine fashion, refers to her only as a male, frightens off any boys she acts interested in, encourages girls who are attracted to her, insults and mocks her femininity, and otherwise goes out of his way to thwart any attempt by her to discover her feminine side. He routinely enforces his desires with violence, and though she is quick to degrade him and beat the tar out of him in return, he always manages to beat her. For some insane reason he has dozens of pictures of himself, baby Ryuunosuke, and women hired for that purpose posing, so many that even he can't remember which one of them is the real Masako Fujinami, and so Ryuunosuke will never know what her mother looked like (although he has claimed at least that Ryuunosuke looks like her mother –- and Lum checked it with a lie detector just in case). Despite his daughter's extreme distaste and discomfort, he also set up for her an Arranged Marriage with a male-to-female Wholesome Crossdresser, Nagisa.
  • Amazingly Embarrassing Parent: As if every terrible thing he did to make his daughter's life a misery wasn't enough, he's actually no better when he's trying to be loving and supporting, since he acts like a lunatic and shouts at the top of his lungs, even when discusssing embarrassing things.
  • Archnemesis Dad: He is quite insistent on treating his daughter like a man, down to subjecting her to violent fisticuffs and paralyzing poisons on a regular basis, and would only let her act feminine over his dead body. Ryuunosuke hates her father. Then again, it's Played for Laughs.
  • Big Entrance: See Making a Splash
  • Catchphrase: "I LOVE THE SEA!!!"
  • Hidden Depths: Still misses Masako, Ryuunosuke's mom, and talks about remarriage brings that out in him.
  • I Reject Your Reality: Mr. Fujinami is so obsessed with the idea that he has a strong, manly son that he will outright reject and deny any attempts to make him see that his "son" is physically female. These include insisting that Ryuunosuke partake in male Physical Education classrooms, which even Onsen-Mark points out is a terrible idea given what hornballs the boys at Tomobiki High are, and insisting that Ryuunosuke's breasts are just "temporary swellings" that will go down if she wears "his special bandages".
  • Irony:
    • Ironically enough, despite his stern believe in stereotypical gender roles he's the one who has taken up the motherly duties around the house (I.e cooking, cleaning, etc).
    • The reason he and Ryuunosuke move to Tomobiki? When Ataru and Lum tried to "help" the father and daughter make peace by chaining them up so they couldn't fight, the Fujinamis instead tore themselves free, causing their beach cafe to collapse in the process.
  • Jerkass: A complete asshole who doesn't care about anyone but himself. He spends his time making life impossible for his daughter just because he doesn't want to accept she's a girl.
  • Jerkass Has a Point: When Ryuunosuke refused to kiss Nagisa, he points out Nagisa's soul will never be able to pass on until she does. As such Ryuunosuke would essentially be damning Nagisa for all of eternity.
  • Making a Splash: Enters a scene riding a wave wherever he may be regardless of logic or physics. It's implied in the anime that this is a genuine super power of his. It's also implied to be genetic as both his daughter and alien bee son are shown doing it.
  • Never My Fault: He very rarely if ever accepts his own fault in things going wrong. In his introductory story, Ryuunosuke punches him in the face twice for hitting her first, and both times he demands to know why she'd hit him instead of somebody else.
  • Real Men Cook: Cooked for his restaurant for years before they went out of business.
  • Serious Business: In-universe, manliness and running the beach cafe. Unlike other, saner proprietors, Mr. Fujinami keeps his cafe open all year around, even during the winter when the beaches pile high with snow. In fact his Establishing Character Moment involves him cursing at the sea for not staying warm, pleasant and inviting like it is in summer all year around, which is quite surprising given his Catchphrase.
  • Small Name, Big Ego: He is such an egomaniac that he proclaims that the ocean needs his beach cafe as badly as he needs the ocean to run it.
  • Unnamed Parent: His actual name is never given in the series.
  • Wanted a Son Instead: He wanted Ryuunosuke to be a boy... so he deludes himself into thinking she is one, and tries to literally beat Ryuunosuke into humoring him.


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

  • Interspecies Romance: A young kitsune with a huge crush on the human girl Shinobu.
  • Kitsune: He is a little fox spirit.
  • Nice Guy: He's maybe the only character in all the story who isn't obnoxious or dangerous.
  • Rescue Romance: Kitsune developed a major crush on Shinobu after she saved him from getting beat up by a gang of punk dogs.
  • Ridiculously Cute Critter: He is very cute.
  • Shapeshifting: Like foxes of mythology, Kitsune can polymorph. His transformation power allows him to make himself look like a short fox version of the other UY characters.

Voiced by: Kaneta Kimotsuki

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

  • Abhorrent Admirer: The disgusting Soban nearly always charges at Shinobu yelling "Shinobu-san suki da!!!" but is always met with a punch to the face.
  • Determinator: He just won't take no for an answer.
  • Gonk: He is a big-lipped, pea brained juggernaut high-school punk.


Voiced by: Hirotaka Suzuoki (JP), Jonathan Soronen (EN, movies)

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.

  • Dogged Nice Guy: Towards Shinobu.
  • Endearingly Dorky: He's awkward, nervous, and tends to say the wrong things and embarrass himself in front of Shinobu. But he's genuinely innocent (one of the few characters in the series who is not a pervert) and Shinobu begins to fall for him because he's truly a Nice Guy, in contrast to all her previous love interests.
  • Hair of Gold, Heart of Gold: He has blond hair and he's the nicest guy in the series bar none.
  • Love at First Sight: He falls for Shinobu right away.
  • Meaningful Name: His name comes from a children's story called "The White Rabbit of Inaba".
  • Nice Guy: Possibly the only truly nice guy in the series.
  • Official Couple: With Shinobu.

Voiced by: Tōru Furuya

Grandson of the ninja bodyguard of Mr. Mendou, Shingo was lost in the Mendou family's "Electric Jungle" when he was young and grew up there all alone, saving only a television set, which he came to believe was his grandfather due to the sporadically useful life lessons he learned from its constant broadcasts. Discovered by accident when he left the jungle in search of a girlfriend, he was reunited with his eccentric grandfather. He was subsequently trained in the arts of ninjitsu and then reluctantly assigned to the role of Mendou's ninja guardian.

He debuted in chapter 301 of the manga, which was adapted into episode 192 of the anime, and later reappeared as Mendo's guardian in chapter 309, which was adapted into the 6th OAV "The Electric Household Guard".

  • Acquired Poison Immunity: A variant that adheres to the spirit of the trope. A childhood growing up in the Electric Jungle, where he was constantly exposed to raw voltage, has made him immune to electrocution.
  • Bunny-Ears Lawyer: He's a very competent ninja, with incredible speed, strength, agility and skills. But he couldn't give a flip about his job, actively disrespects (or even dislikes) his boss, and would rather lay around watching TV. He also points things out when his boss gives him stupid orders, like sending Shingo to look for Ryoko when Shingo doesn't actually know who Ryoko is or what she looks like.
  • Damage Reduction: He's completely impervious to electricity.
  • Hilariously Abusive Childhood: He was abandoned in a jungle full of electrified trees and electricity-shooting animals as a small child by his senile grandfather, who took him there and then forgot him. When reunited with his grandfather, the man tends to attack him for not being suitably respectful to Shutaro Mendou, and often forgets who his grandson actually is.
  • Love at First Sight: Falls in love with either Shinobu (manga) or Lum (anime) on first seeing them. In his debut story as Mendo's bodyguard, he falls in love with Ryoko upon seeing her and tries to court her.
  • Mysterious Guardian: Invoked, in that Shingo is supposed to be Shutaro Mendou's ninja bodyguard, who remains hidden until needed and even then tries to protect his master without being seen. Subverted, in that Shingo genuinely doesn't care about the job and would rather be watching TV or going on a date.
  • Raised by Grandparents: Played with. His parents seem to have died when he was very young, leaving him to be raied by his grandfather. But...
  • Raised by Wolves: Because Shingo's grandfather is senile, he lost Shingo in the Electric Jungle when Shingo was young, leaving Shingo to raise himself with nothing but his native wits and the "advice" of a television set, which he mistakenly believed was his grandfather.
  • Saw "Star Wars" 27 Times: Shingo's first and foremost love is watching television. Even after becoming a ninja bodyguard, he tends to abandon his role so he can watch TV.
  • Wild Child: Having had to rear himself all alone in a jungle full of electrified trees and lightning-throwing animals since he was young has left Shingo with very pooor social skills and lackluster education at best.

     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 and sweet bean-flavored kakigori. Long ago he was engaged to Ryuunosuke through their parents, and fell in love with her upon meeting her. Debuts in manga chapter #341 and OAV #5.

  • Arranged Marriage: With Ryuunosuke.
  • Back from the Dead: Nagisa gets a new flesh-and-blood body by drinking the tear of the giant sea urchin.
  • Big Eater: He's a huge glutton, and even having literally eaten himself to death hasn't changed that fact. It's actually one of the reasons that Ryuunosuke doesn't like him very much. To put things into context, Mr. Shiowatari died from overeating after consuming his 98th serve of kakigori in a row...Nagisa managed to eat his 166th serving before dying.
  • Charles Atlas Superpower: To the point Ryuunosuke cannot compete with him. He got so strong from participating in the annual beach sumo wrestling competitions, which he won every year.
  • Cordon Bleugh Chef: Suggested that he and his father invent a signature dish to make their seaside restaraunt more popular... and the dish they came up with was kakigori (shaved ice) flavored with sweet beans and sea urchin. The idea visibly repulses Ataru, Mendo and Shinobu.
  • Cute Ghost Girl: In his first appearance, Nagisa was a ghost and since he looks so feminine, everyone thought he was a cute girl.
  • Foreshadowing: His true gender was anticipated by Ataru and Mendou not trying to grope or woo him, and is revealed after they both realized this.
  • Gender-Blender Name: Nagisa is a name which is often given to girls, but boys have this name, too. Makes sense since his father wanted a daughter and raised Nagisa as such.
  • House Husband: Because he acts so much like a Yamato Nadeshiko, despite being male, he seems content to take the role of the "wife" after marrying Ryuunosuke.
  • Love at First Sight: Towards Ryuunosuke. He even claims on their first meeting that he cannot pass on to the afterlife without receiving a kiss from Ryuunosuke.
  • Masculine Girl, Feminine Boy: Feminine Boy to Ryuunosuke's Masculine Girl.
  • No Sense of Personal Space: Nagisa is extremely physically affectionate, and his exaggerated "touchy-feely" nature is one of the things that alienates others — especially his fiancee, who receives the bulk of his attention.
  • Perfectly Arranged Marriage: You'd think that a hyper-feminine guy and a hyper-masculine girl would be a match made in heaven. You'd be dead wrong. Ryuunosuke loathes Nagisa, finding his gender-blurring dress and mannerisms to be creepy as all hell since she herself wants to be "normal", and especially being put off by the way he loves to constantly touch her despite her protests.
  • Raised as the Opposite Gender: Similar to Ryuunosuke's case, Nagisa's father raised him as a girl because he wanted a daughter. Nagisa seems to be more comfortable with his upbringing than Ryuunosuke, though.
  • Silk Hiding Steel: With his very feminine manners, no one though he could win against Ryuunosuke, which he did in seconds.
  • Unsettling Gender Reveal: He reveals he's a man by showing off his bare chest to Ryuunosuke.
  • Wholesome Crossdresser: Zigzagged. Nagisa dresses in women's clothing and acts in a very feminine manner mostly because his father forcibly raised him as a woman, in counterpoint to Ryuunosuke's father. However, Nagisa also genuinely enjoys crossdressing and is, frankly, something of a pervert, albeit usually unintentionally.
