History Characters / UruseiYatsuraWeirdoes

* PetTheDog: 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.

* AdaptationalLateAppearance: In the manga, he appears in an early story where Ataru and Lum travel to the future. The anime has him appear until the Inaba story arc, which is one of the last arcs of the series.

* CassandraTruth: Ran tried telling her while she was being spanked that it was actually Lum that wet the bed. She never believed her and punished her even harder for "lying" or "letting (her) friend take the fall for (her)".

** In the first anime, she automatically assumes that it was Ran who flooded the bathroom and doesn't believe her daughter when she (truthfully) says it was actually Lum. Then proceeded to spank her for "lying", which in turn made Lum scared of her and frame Ran for her bed wetting. There's no scene like this in the manga or 2022 anime.

* DidntThinkThisThrough: After Ran told her mother that it was Lum that wet the bed, not her, she proceeded to harshly ask Lum if that's true, even saying that she would spank Lum for it. Why she would think that a little girl would admit to her fault knowing that after seeing her violently spank her own daughter beforehand is anyone's guess.

* DisproportionateRetribution: She was a FAR stricter parent compared to Lum's and much harsher when it came to discipline. An action that Lum's parents would deem innocent (like wetting the bed), she would viciously spank Ran for. And for an action that caused Lums parents to spank her, she punished Ran by grounding her for half a year.

* PetTheDog: She was actually very nurturing to Ran when she was sick and throwed her a descent birthday party.

* SelectiveObliviousness: Ran did do a few things that she considered bad behavior when she was young (Ran admitted to Lum that she wet the bed once) and Lum didnt do anything bad (in front of her) whenever she stayed at her house. So she was quick to assume that Ran was responsible for anything bad that happened (even when Lum didn't even try to frame her, or even when Lum tried taking the fall for her) because she got it in her head that her daughter was "shameful" and Lum was an angel.

* WouldHurtAChild: She would (rather violently) spank her daughter to the point of tears for perceived bad behavior. Also, the reason Lum let Ran take the blame for her was because Rans's mother specifically said that she would have spanked Lum too for misbehaving, even though she wasnt her daughter. She also wasn’t against smacking her daughter on the back of the head while harshly criticizing her, once again hard enough to make Ran cry. Keep in mind they were FIVE at the time.

* InconsistentSpelling: She's called "Kurala" in the Viz Media transltion of the manga.

* IJustWantToHaveFriends: He just want to become friends with the humans who come to visit his "home" at the pool.

* PaperThinDisguise: His ability to shapeshift is rendered moot by the fact that all of them retain his small stature as well as his cute little nose, small, tiny, mouth and beady black eyes, as well as his ears and tail being visible too.

** Like Lum, Elle is a beautiful AlienPrincess who wishes to claim Ataru as her husband because [[AccidentalMarriage he beat her in a game of tag]]. [[spoiler:With the difference that it turns out that Ataru actually ''lied'' about beating Elle.]] Both try forcing Ataru to marry them even after he resists, but Lum is one hundred percent committed with Ataru alone. Elle, on the other hand, has amassed a thousands-strong "harem" of handsome men by seducing them and then cryogenically freezing them, but hypocritically claims to only love Ataru alone, despite still maintaining her "collection".

* KidAnova: Flirts with every girl he sees. Howewer Ten is still essentially a child and quite naïve; around women he is usually cute and diminutive.

* SmallGirlBigGun: She can uses her bazooka, machine gun and explosives to cause massive destruction.

* TownGirls: The tomboyish, bad-mouthed and violent Butch to Lum's Neither and Oyuki's Femme.

* AnIcePerson: She has the power to generate ice and snow, sometimes by blowing across her hand, but also simply radiationg cold. She can selectively grow ice in any shape, size and quantity that she likes, and has repeatedly been seen imprisoning people in ice blocks as well as creating ice "spears" to threaten or capture people withouit freezing them.

* TheTease: In her introduction story, Oyuki undresses in front of Ataru to show off her skimpy leotard before inviting him into her bedroom. The 2022 anime takes it even further, as Oyuki wraps her arms around Ataru's neck and leads him to lay on top on her in bed.
* TownGirls: The calm, demure and feminine Femme to Lum's Neither and Benten's Butch.

* TheExsNewJerkass: Later on, Lum's ex-boyfriend Rei starts dating Ran, even if only to get food from her. While this makes her less actively antagonistic towards Lum, Ran still dislikes her and gets paranoid whenever Lum is in close proximity to Rei, accussing Lum of still having feelings for Rei and planning to steal him back from her, even though Lum clearly ''hates'' Rei.

* GirlyGirlWithATomboyStreak: She's extremely girly, and both her hair and clothes are pink. When angry, however, she behaves more like gangster and her speech patterns turn much more crude.

* NeverMyFault: Even with the FreudianExcuse, 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.

* TokenEvilTeammate: Out of Lum's friends, she's the only who has devious and malicious intentions to the point of often being a FalseFriend to the others, especially Lum.

* WithFriendsLikeThese: Despite Lum viewing Ran as a friend, Ran hates her and is out for revenge for all the times Lum inadvertedly made her suffer.

* DubNameChange: Changed to Raymond in the BBC GagDub

* MsFanservice: She wears a skimpy outfit, has several bath scenes and in one occasion her breasts are visible when one of her tengu remove her bodice.

* {{Stripperiffic}}: Kurama has an outfit well established in all the episodes in which she 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 ImpossiblyLowNeckline.

Sugar, Ginger and Pepper. A trio of teenage girls who attended 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.

* EstablishingCharacterMoment: In their introduction, they "greet" Lum, Benten , and Oyuki by [[TongueOutInsult sticking out their tongues]], just to make clear they're obnoxious brats right away.

* HumanAliens: Like other aliens in the series, Sugar and Pepper look just like humans. Ginger mostly looks human too, but has [[CatGirl cat like ears]].

An alien girl from a race of {{Human Alien}}s based on the Seven Lucky Gods, who name is typically translated as the "Gods of Luck Race/Gang", and Lum's childhood friend. In the anime, she's shown to be the head of a hover-biker gang made up entirely of Lucky God girls like herself, all daughters of Lucky God aliens who are named after the other six members of the actual pantheon (whereas Benten is based on the sole female member of the pantheon); Kuro (Daikokuten), Meguro (Ebisu), Shala (Bishamonten), Roku (Fukurokujin), Kotobuki (Jurojin) and Tei (Hotei).

* AdaptationDyeJob: She has sky blue hair in the 1981 anime, while the 2008 OVA and ''All-Stars'' anime give her bluish white hair to make it look like ice. Likewise, the leotard under her kimono is orange in 1981 anime, but light blue in the ''All-Stars'' anime.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/lum_fpc.png]]

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.

* BigEater: He got so big due to eating so much of his wife's food. The second opening for ''All Stars'' even shows him happily gorging on sweet potatoes with Rei in his "Tiger-Bull" form, matching his boundless appetite.
* BigFun: He's a large and overweight man who is very affable and lovable even when he's threatening to invade Earth.
* BigOlEyebrows: He has possibly the thickest eyebrows out of the cast.
* FormerlyFit: He gained ''a lot'' of weight because his wife stuffed him up with her cooking.
* {{Gonk}}: Only a few one panel joke Oni have been as monstrous as Lum's father.
* HenpeckedHusband: He likes to pretend he's the tough and powerful man of the house, but his wife very firmly puts him in his place, even beating him up if he really makes her mad. He even bonds with Ataru because neither of them can win an argument against their strong-willed YamatoNadeshiko wives.
* IWasQuiteALooker: He used to be handsome and thin. Decades of being spoiled by his wife left him {{gonk}}y and grossly fat.
* TheUnapologetic: One time, Lum's father eats his wife's meal after he finishes his. Then ''he'' demands that she apologize when she kicks him out to put him in his place.

[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/lum_mpc.png]]

A pretty woman who can only speak in the oni language.

* GoodParents: Lum and her mother seem to have the best mother/child relationship out of everyone else in the series, as the only one who's not abusive or totally absent from the narrative. When Lum's mom arrives for the parent/teacher conference, Lum's overjoyed to see her and rushes into her arms. This is especially prominent when she's contrasted with Ran's mother, to the point of trying to get the other woman to calm down when it looked like Ran wet the bed at Lum's house (of course it was Lum).
* InTheBlood: Like her daughter, she's an affectionate, dutiful and loving wife not above disciplining her husband when he steps out of the line, managing to get him fear her anger.
* MyHovercraftIsFullOfEels: Lum sometimes translates when her mom is present, but she must be doing something very wrong. In one example, Mendo's mother challenges Lum's mom to a duel. When Lum relays this, her mom begs Mendo's mom to reconsider, since they're both women... and besides, she's already married!
* SdrawkcabSpeech: In the 2022 anime, her lines are just Fumi Hirano's lines backwards, and the Japanese broadcast even has an additional track [[https://twitter.com/naonao3naonao3/status/1603490563525087232 where her lines aren't backwards]].
* StarfishLanguage: She does not speak any Earth language, with strange characters and symbols being used in the manga or subtitles whenever she's speaking.
* StrongFamilyResemblance: She strongly resembles her daughter except with her hair cut short.
* YamatoNadeshiko: Much like her daughter, Lum's mother is a beautiful alien woman who is willing to lavish her husband with affection, but is able to rule her household with an iron fist and unwilling to put up with her husband's rudeness.

!!Ten's mother
!!!'''Voiced by:''' Creator/KeikoYokozawa
[[quoteright:255:https://static.tvtropes.org/pmwiki/pub/images/tens_mother_4.png]]

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 (ab)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 [[https://www.artelino.com/articles/edo_firemen.asp the firemen of Edo Japan]].

* AbusiveParents: Zigzagged. She genuinely loves Ten, but she also left him permanently traumatized by telling him horror stories about the horrible punishments she would dole out to arsonists and pyromaniacs. She's completely oblivious to the fact that these stories have left Ten literally too scared to cry since he was a little baby, having thought he ''enjoyed'' them, so her abuse is completely unintentional.
* AffectionateGestureToTheHead: She casually pets Ten's head when asking him if he has been a "good boy"
* BerserkButton: Arsonists and pyromaniacs. When Ten was living with her, she would tell him stories about the horrific punishments she and her colleagues would inflict on any arsonists that they caught. Considering Ten's own fire-related shenanigans, he understandably is ''utterly terrified'' of his mother finding out about the things he has done.
* BewareTheNiceOnes: When she introduces herself to Ataru, she is perfectly pleasant, polite and nice, even taking Ataru's attempts to hit on her in stride. It's only when the topic of arsonists and pyromaniacs comes up does the temperature drop, showing why Ten is so afraid of his mother finding out about his own fire-related antics.
* BloodKnight: She enjoys fighting fires and arsonists with equal gusto.
* CharacterCatchphrase: She screams "FIRE!!" whenever anyone rings a firebell, followed by her rushing to put out the flames.
* DoesntKnowTheirOwnChild: She doesn't know Ten is a fire-breathing BrattyHalfPint because Ten is ''terrified'' of what his mother might do to him if she knew his true self and pretends to be well-behaved whenever she's around.
* InHarmsWay: It's implied that she feels the most comfortable when fighting fires -- the bigger, the better.
* ObliviousGuiltSlinging: 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.
* ParentsAsPeople: She's so devoted to her job that a robotic nanny and Lum raised Ten in her place, but regrets not being able to spend more time with her son.
* UnnamedParent: Like Lum's mother and father (and Ataru's), we never get a name for her.
* {{Workaholic}}: She constantly carries around her firefighting equipment.

Sugar, Ginger and Pepper. A trio of teenage girls who attended 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.

!!In General
* AdaptationDyeJob: In the manga, Sugar's hair is pink and Ginger's hair is black. In the 1981 anime, their hair colors were changed to black and blonde respectively. However, later anime adaptations make Sugar's hair pink like in the manga. Meanwhile, Ginger's hair is blonde in the 2008 OVA and black with a dark green tint in the 2022 anime.
* BigBadWannabe: 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 a real threat.
* BlondeBrunetteRedhead: In the 2008 OVA, Sugar has pink hair, Ginger has blonde hair, and Pepper has black hair.
* BrattyHalfPint: They're a bunch of stupid brats who play pranks on their "senior delinquents" so they can pretend to be a gang, but are just annoying more than anything.
* BullyingADragon: They pick a fight with [[BadassBiker Benten]], [[ShockAndAwe Lum]], and [[AnIcePerson Oyuki]], despite each of them being known as a force to be reckoned with. Even the Spice Girls know they're screwed if Benten's "gang" gets serious against them.
* TheDividual: The three of them are often seen together, causing trouble for Lum and her friends.
* EdibleThemeNaming: All three of them are named after spice-related condiments.
* EstablishingCharacterMoment: In their introduction, they "greet" Lum, Benten , and Oyuki by [[TongueOutInsult sticking out their tongues]], just to make clear they're obnoxious brats right away.
* GoldfishPoopGang: These three lack the sense, power, or competence to be any real threat most of the time.
* HumanAliens: Like other aliens in the series, Sugar and Pepper look just like humans. Ginger mostly looks human too, but has [[CatGirl cat like ears]].
* IneffectualSympatheticVillain: They're such stupid and incompetent antagonists that all their evil plans either backfire or fail humiliatingly.
* KarmicButtMonkey: 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.
* NotSoHarmlessVillain: 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 HeelFaceTurn to help Lum.
* RedBaron: They call themselves "Seven-colored" Sugar, "Buddah" Ginger, and "Poisonous Snake" Pepper.
* SmallNameBigEgo: They give big speeches about how they're superior to Lum, Benten, and Oyuki. They... ''[[EpicFail really]]'' ...aren't.
* SuperSentaiStance: They did this at least once in the anime, ironic since ''none'' of these girls are heroic.
* TerribleTrio: 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 [[UnknownRival ignored by them]].
* WhatKindOfLamePowerIsHeartAnyway: While ChameleonCamouflage, FauxDeath, and GivingThemTheStrip ''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 [[ShockAndAwe Lum]], [[BadassNormal Benten]], and [[AnIcePerson Oyuki]], who are flat-out leagues above them.

The leader of the trio. She wears a Chinese-style tunic and bun hairstyle. She has the ability to blend in with her surroundings to the point of invisibility.
----
* AnimeChineseGirl: Although she's an alien, Sugar wears a Chinese-style outfit and has the double bun hairstyle that's common for Chinese girls in anime.
* ChameleonCamouflage: Sugar's special ability allows her to blend in with her surroundings. While this ''would'' be useful for sneak attacks, Sugar's habit of [[CallingYourAttacks announcing the technique as she's using it]] makes it easy to track her down.
* RoseHairedSweetie: {{Inverted|Trope}}. Sugar's hair is pink (except in the 1981 anime), but she's every bit as bratty as Ginger and Pepper.

* CatGirl: Despite being an alien, Ginger looks like a girl with cat ears.
* FauxDeath: Ginger is able to slow down her bodily functions to the point that an untrained observer will believe that she is dead.
* RaceLift: Ginger's skintone is much lighter in the 1981 anime. The 2008 OVA and 2022 anime do give her the dark skin from the manga.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/ran_mom_2023.png]]

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.

* AbusiveMom: She was a ''very'' strict parent and her go-to whenever (she thought) Ran did something wrong (like wetting the bed) was to violently spank her to the point of making Ran cry. And thanks to Lum, Ran was often blamed for things that she didn't even do. What separates her from [[ToughLove a parent that is strict and harsh because they think it will help their child be better]], [[NotSoWellIntentionedExtremist is that it is clear her punishments are more because she’s mad at Ran than anything else.]] She also hit Ran while harshly comparing her to Lum, made it clear she liked the other girl better and verbally assaulted Ran while spanking her which can be considered emotional abuse. Her very first appearance even has her automatically blaming something bad that happened on Ran without considering it could have been Lum, then spanking Ran and verbally assaulting her for lying when she said it was actually Lum.
* AdaptationDyeJob: Her bikini is black in the original manga and anime, but the 2022 anime made it golden.
* AdaptationalDumbass: In all three versions, she automatically believes that Lum was trying to take the fall for Ran breaking one of her antiques then punished her daughter for it. While she actually ''was'' right, her reasoning is less reasonable in the original anime. In the manga and 2022 anime, she sees through it because she sees the darts in Ran's hands match the one in the doll. [[RightForTheWrongReasons In the original anime, she thinks for a moment then concludes that it was really Ran since Lum is the "good girl" and Ran is "shameful."]]
* CassandraTruth: Ran tried telling her while she was being spanked that it was actually Lum that wet the bed. She never believed her and punished her even harder for "lying" or "letting (her) friend take the fall for (her)".
* CharacterExaggeration:
** In the first anime, she automatically assumes that it was Ran who flooded the bathroom and doesn't believe her daughter when she (truthfully) says it was actually Lum. Then proceeded to spank her for "lying", which in turn made Lum scared of her and frame Ran for her bed wetting. There's no scene like this in the manga or 2022 anime.
** Inverted example: In the manga, when Ran was tricked by a conman into buying lots of expensive gadgets, her mother grounded her for half a year. In the original anime, she just took away her allowance for that time-period.
** Another inverted example: The 2022 anime tones down her abusive treatment of Ran by removing the scenes where she gives her physical punishments, but she still screams and verbally assaults her.
* DidntThinkThisThrough: After Ran told her mother that it was Lum that wet the bed, not her, she proceeded to harshly ask Lum if that's true, even saying that she would spank Lum for it. Why she would think that a little girl would admit to her fault knowing that after seeing her violently spank her own daughter beforehand is anyone's guess.
* DisappointedInYou: She called Ran a shameful daughter for her (supposed) bedwetting and for (supposedly) not being as good of a child as Lum. She especially called Ran shameful for "letting" Lum try and take the fall for her on one of the few things Ran actually did do wrong (it was to try to make up for getting her in trouble before but she didn't know that).
* DisproportionateRetribution: She was a FAR stricter parent compared to Lum's and much harsher when it came to discipline. An action that Lum's parents would deem innocent (like wetting the bed), she would viciously spank Ran for. And for an action that caused Lums parents to spank her, she punished Ran by grounding her for half a year.
* TheDreaded: Both Ran and Lum were afraid of her.
* EstablishingCharacterMoment:
** In her first scene in the manga, it's her telling her daughter right before she goes to sleep that if she were the bed she will spank her, and Ran replies with a scared “yes ma’am”.
** In her first scene in the original anime, she automatically assumed the bathroom flooding was Ran's fault. This is just one of the many misdeeds Ran got blamed and unfairly punished for.
* FieryRedhead: Her daughter got her red hair and explosive temper from her.
* HairTriggerTemper: She was quick to anger, her spankings were violent and she even smacked her daughter and made her cry for no other reason than was reminded [[HorribleJudgeOfCharacter of how much Lum is a sweet girl compared to her.]]
* HateSink: She has little to no characterization aside from being Ran's AbusiveMom who traumatized her daughter into becoming a psycho and contributing to the latter's resentment towards Lum.
* HorribleJudgeOfCharacter: She thought her daughter Ran was a naughty brat while Lum was an angel. She couldn't have been more wrong at that age.
* {{Irony}}:
** She thought Ran was a bad kid when she was little, but her constant punishments in return ended up making Ran into a psycho as a teenager.
** She always fell for Lum's attempts at framing Ran for her bed wetting, but when Lum tried to take the fall for Ran accidentally breaking one of her antiques (a dancing robot toy) she immediately saw through it.
* {{Jerkass}}: Strict parenting aside, she wasn't very nice to her daughter overall, harshly judged her for unintentional mistakes, seeing the worst in her and tended to automatically assume Ran did something bad (then promptly punish her) without bothering to determine if it was another person, such as blaming Ram of flooding the bathroom when it was really Lum (which then made Lum scared of her and start framing Ran onward) to naturally assuming that a pee-stain in a drying bedsheet came from Ran (again it was Lum).
* MisplacedRetribution: She harshly punished Ran for things that Lum actually did. Most of the time it was because Lum framed Ran, but a few times it was because she automatically assumed the worst in her daughter.
* PetTheDog: She was actually very nurturing to Ran when she was sick and throwed her a descent birthday party.
* PosthumousCharacter: We only ever see her in flashbacks. Her current status and relationship with her daughter is unknown.
* SelectiveObliviousness: Ran did do a few things that she considered bad behavior when she was young (Ran admitted to Lum that she wet the bed once) and Lum didnt do anything bad (in front of her) whenever she stayed at her house. So she was quick to assume that Ran was responsible for anything bad that happened (even when Lum didn't even try to frame her, or even when Lum tried taking the fall for her) because she got it in her head that her daughter was "shameful" and Lum was an angel.
* SexyBacklessOutfit: Her bikini top only covered her breasts, leaving her back fully bare.
* StrongFamilyResemblance: She looks exactly like an older Ran.
* UnnamedParent: We never get a name for her.
* WalkingSwimsuitScene: Flashbacks only show her wearing a bikini.
* WhyAreYouNotMySon: Thanks to Lum framing Ran for her bed wetting, she thought Lum was a better child than her daughter and made that clear to Ran. She once smacked Ran in the back of the head so hard it made her cry, while harshly asking her why she couldn't be more like Lum.
* WouldHurtAChild: She would (rather violently) spank her daughter to the point of tears for perceived bad behavior. Also, the reason Lum let Ran take the blame for her was because Rans's mother specifically said that she would have spanked Lum too for misbehaving, even though she wasnt her daughter. She also wasn’t against smacking her daughter on the back of the head while harshly criticizing her, once again hard enough to make Ran cry. Keep in mind they were FIVE at the time.

Now she has came to claim her husband. [[spoiler:Their engagement becomes null after Ataru remembers he lied about winning their game.]]
* AndNowYouMustMarryMe: She sends her minions to Earth to claim Ataru as her husband and he's down for it until he finds out about Elle's "hobby" to collect and freeze handsome men. When Ataru tries to call the wedding off, she takes him prisoner and tries forcing him to go through with it, only to be stopped by Lum.
* BigBad: She's the villainess of the first movie.
* BitchInSheepsClothing: She seems nice at first, until she reveals that she makes a "hobby" out of freezing her lovers to add them to her large collection.
* BondVillainStupidity: 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.
* CanonForeigner: She's an original character of the first movie and doesn't exist in the manga.
* ChildhoodMarriagePromise: 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. [[spoiler:At the end it turns out Ataru never stepped in her shadow in the first place and therefore their engagement is null.]]
* TheCollector: 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).
* DudeMagnet: She's attracted a considerable number of suitors by the time she shows up.
* EvilCounterpart: To Ataru and Lum. Rather, she's a more flawed and antagonistic counterpart.
** Ataru and Elle are both lusty pursuers of the opposite sex, but Ataru is open about being a HaremSeeker, whilst Elle is a {{hypocrite}} who seduces men as a "hobby" and then keeps saying she only loves Ataru. Also, Ataru would never ''force'' a woman to join his harem, as opposed to Elle having no shame about cryo-freezing her would-be suitors, treating them more like trophies than Ataru ever would.
** Like Lum, Elle is a beautiful AlienPrincess who wishes to claim Ataru as her husband because [[AccidentalMarriage he beat her in a game of tag]]. [[spoiler:With the difference that it turns out that Ataru actually ''lied'' about beating Elle.]] Both try forcing Ataru to marry them even after he resists, but Lum is one hundred percent committed with Ataru alone. Elle, on the other hand, has amassed a thousands-strong "harem" of handsome men by seducing them and then cryogenically freezing them, but hypocritically claims to only love Ataru alone, despite still maintaining her "collection".
* FlowersOfFemininity: She's a beautiful queen and wears a white rose in her hair, as well as having a "rose" theme to all her belongings. Even her ''planet'' looks like a rose!
* ForgottenFriendNewFoe: She met Ataru when they were both little kids, but Ataru forgot all about her until she shows up during the movie.
* GodSaveUsFromTheQueen: She's a beautiful queen beloved by the people of her planet, but the men that she takes a liking to will either become part of her frozen collection or her slave.
* LeotardOfPower: She wears a rose-red leotard beneath a regal white cape.
* LightIsNotGood: She's very beautiful and wears a white cape over her body, but she's still a villain and nowhere near as nice as she seems.
* LordCountry: Exaggerated. Elle rules over an entire ''planet'' that shares her same name.
* NakedOnArrival: Her first official appearance shows her naked from the back as she comes out of her bath.
* PsychoPink: She has rose-colored hair and serves as the main villain of the first movie. Although she doesn't seem bad at first, even the perverted Ataru is repulsed by Elle's true twisted and depraved nature.
* RoseHairedSweetie: Subverted. She has pink hair and presents herself as a sweet woman who is smitten with Ataru, but she's actually a shameless man-eater who treats handsome men as collectibles and tries forcing Ataru to marry her after he realizes her true nature.
* SignificantGreenEyedRedhead: Her rose hair and green eyes signify her relevance as royalty and the villain of the first movie.
* TermsOfEndangerment: She calls Ataru "Honey" because she thinks he's her husband. He's pleased with her displays of affection until he discovers what a dangerous woman she really is.
* TheUnfettered: She's determined to have her way no matter what.
* UniversallyBelovedLeader: She's a beloved ruler on her homeworld.
* VillainBall: She just ''had'' to try and freeze Mendou, which only ends up exposing her true nature as an evil man-eater to Ataru and makes him lose any intention to marry her willingly.
* VillainousCrush: Elle is the first movie's villain because she wants to take Ataru from Lum and make him her husband. Ataru actually likes the idea at first, but changes his mind after he finds out about [[TheCollector Elle's frozen collection of handsome men]]. Elle still attempts to make him marry her by force.
* WhiteAndRedAndEerieAllOver: Her outfit consists of a red leotard with a white cape and accessories. Her color scheme is a hint at her being dangerous despite good first impressions.
* WorldsMostBeautifulWoman: She's considered the most beautiful woman of ''the entire universe''.
* {{Yandere}}: She has the "hobby" of imprisoning and freezing the men she's attracted to, even keeping a very big collection inside a giant refrigerator. When Ataru realizes this and changes his mind about marrying her, Elle will ''not'' let him go willingly and is determined to make Ataru hers, whether he wants it or not.

!!Rupa
!!!'''Voiced by:''' Creator/KanetoShiozawa (JP, Movie 5)
[[quoteright:255:https://static.tvtropes.org/pmwiki/pub/images/rupa.jpg]]

The prince of a world of total darkness, giant mushrooms, and flying pigs. It was arranged by his great-grandfather Uba that he would marry Lum. He is the central antagonist of the final manga arc, which was animated as the movie ''[[Recap/UruseiYatsuraTheFinalChapter The Final Chapter]]''.

* AndNowYouMustMarryMe: He kidnaps Lum and tries to force her to carry out their ArrangedMarriage.
* ArcVillain: He's the antagonist for the final arc where he goes to Earth to claim Lum as his bride.
* ArrangedMarriage: It was arranged by Rupa's great-grandfather that he would marry Lum.
* BeingEvilSucks: 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.
* BetaCouple: With Carla. Their dysfunctional relationship parallels Ataru and Lum's in the final arc. Unlike the main couple getting an open ending, Rupa proposes to Carla and they look happy despite how rocky their relationship has been.
* BewareTheSillyOnes: He's ''not'' an intimidating figure in the slightest. But he unwittingly achieves something that nobody else has in the entire story; destroying Ataru and Lum's trust in each other and causing them to legitimately break up by swapping out the real Lum for an obedient mushroom duplicant at his wedding, causing Ataru to believe that Lum really had chosen Rupa over him and causing him to denounce the real Lum as a two-timing traitor when she broke free in the confusion.
* BigBadWannabe: 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.
* ChildhoodFriendRomance: With Carla. They were close when they were children, but her going {{Yandere}} because of his engagement to Lum made him terrified of her. At the end, however, Rupa admits that he doesn't really want to marry Lum and asks Carla to marry him.
* DisposableFiance: He intended to marry Lum, but ultimately ends up not going through with it.
* HilariouslyAbusiveChildhood: His {{Yandere}} childhood friend Carla has repeatedly assaulted him for most of their lives, sometimes even blasting him with a bazooka. Flashbacks to Carla abusing his child self are PlayedForLaughs.
* HonorAmongThieves: Despite his antagonism towards Ataru, and his breaking things off with Lum, he agrees to have his pigs eat the mushrooms threatening the Earth regardless of whether Ataru wins or loses the match.
* HonorThyAbuser: After giving up on marrying Lum, not only does Rupa instantly forgive Carla for terrorizing him, assaulting him, and almost killing him for years, he even asks her to marry him.
* InLoveWithLove: As Lum and Ten point out, Rupa would have been fine with an ArrangedMarriage with anyone as long as his fiancée was cute. He's confronted about how he's completely disregarding his childhood friend Carla's feelings for him, causing her to go mad over Rupa preferring to marry a stranger over her.
* InTheHood: He's rarely seen outside his hooded black cloak.
* KnightOfCerebus: His arrival kicks off the final arc, which ultimately has the highest stakes seen in the whole story.
* LoveBeforeFirstSight: His great-grandfather gave him a picture of a little Lum when he was a kid. Since she's cute, he decided to go through with their ArrangedMarriage even if he had to force her into it.
* LovingAShadow: He ''thought'' he would like Lum more than Carla, only based on the assumption that Lum wouldn't be as possessive and violent. Lum herself points out she ''is'' very possessive and violent towards the man she loves, so there's no reason why Rupa should like her, especially when they're complete strangers.
* MarryForLove: At the end, he realizes he isn't in love with Lum and breaks off the ArrangedMarriage to marry Carla, the woman he really loves.
* StupidEvil: 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.
* UnknowinglyInLove: 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.

[[folder: Carla]]
!!Carla
!!!'''Voiced by:''' Creator/YouInoue (JP, Movie 5)
[[quoteright:255:https://static.tvtropes.org/pmwiki/pub/images/carla_30.jpg]]

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. Like Rupa, she is a central character in the final manga arc, which was animated as the movie ''[[Recap/UruseiYatsuraTheFinalChapter The Final Chapter]]''.

* AbhorrentAdmirer: To Rupa. He did think she was cute when they were kids, but after he told her about his engagement to Lum, Carla became an unhinged {{Yandere}} who obsessively stalks and attacks him because he doesn't reciprocate her feelings. Rupa naturally ended up terrified of her after years of abuse.
* BetaCouple: With Rupa in the final arc. Their relationship problems and Carla's abusive possessiveness make them an obvious parallel to Ataru and Lum, but unlike those two having an open ending, Carla gets a definite happy ending with Rupa admitting he loves her and asking her to marry him.
* ChainmailBikini: Beneath her robe, she wears a skimpy armor that looks like a bikini.
* ChildhoodFriendRomance: She has been obsessively in love with Rupa since they were kids, but their relationship soured ''a lot'' since Carla went crazy with jealousy because Rupa is engaged to Lum. At the end, however, Rupa gives up on Lum and asks Carla to marry him.
* ClingyJealousGirl: Ever since Rupa told her about his engagement to Lum, she has constantly threatened and terrorized Rupa out of jealousy.
* CryIntoChest: When Rupa ''finally'' admits he was wrong about wanting to marry Lum and asks Carla to marry him, Carla hugs him tightly and breaks down in tears.
* DisproportionateRetribution: Carla ''does'' have a legitimate grievance against Rupa, as he readily agreed to marry a complete stranger when he (sort of) had a relationship with Carla when they were kids. However, Carla ''definitely'' went overboard by turning to dangerously possessive and jealous behavior, to the point she has repeatedly assaulted and almost killed Rupa over the past decade.
* DoubleStandardAbuseFemaleOnMale: She has spent most of her life attacking Rupa with heavy weaponry, but this is treated as merely a comedic flaw, even somewhat justified, and Rupa ultimately proposes to her after Lum talks him out of the ArrangedMarriage, even though realistically he has every reason ''not'' to want to marry the crazy girl who has obsessively stalked and attacked him for a decade.
* DrivenByEnvy: Carla was pissed when Rupa told her he was going to marry some girl he'd never even met when he already had her. She has spent years making his life hell since then, and after he kidnaps Lum to force her to marry him, Carla is hellbent on ruining their wedding.
* EarlyBirdCameo: At the start of Episode 18 of the 2022 anime, there's a glimpse of Carla's silhouette.
* EvilWearsBlack: She wears a black wedding dress as she crashes Rupa's forced wedding with Lum, fully intending to stop it even if she has to kill both Rupa and Lum.
* IfICantHaveYou: After Rupa claims to hate her, Carla [[BerserkerTears bursts into tears]] and declares that she's going to commit a MurderSuicide with him, as she won't let anyone else have him.
* InconsistentSpelling: She's called "Kurala" in the Viz Media transltion of the manga.
* KarmaHoudini: After spending years making Rupa's life hell because he kept refusing to marry her, Carla ultimately gets a happy ending with Rupa proposing to her.
* LoveHungry: When she was a child, she forced Rupa to say he loved her by ''holding him at gunpoint''. After she learned he was already engaged to another girl, Carla has been obsessed with assaulting Rupa until he agrees to marry her.
* MurderTheHypotenuse: She was willing to kill Lum to prevent Rupa from marrying her, either unaware or not caring that Lum wasn't on board with this engagement.
* NeverMyFault: She blames Rupa's engagement to Lum as the only reason why he refuses to marry her instead, but a lot of Rupa's reluctance to accept her "advances" could be easily explained as her own fault for resorting to attacking Rupa repeatedly on end for years after hearing he was in an ArrangedMarriage. Rupa even lampshades that this behavior is ''why'' he grew to fear her and want nothing to do with her.
* NotGoodWithRejection: Carla loves Rupa, but he's engaged to another girl. In response to feeling rejected by Rupa, Carla constantly chases him down, attacks him, and even tries to ''kill'' him.
* SatelliteLoveInterest: All aspects of her character tie back into Rupa and her obsession with making him marry her.
* SmallGirlBigGun: The weapons she hauls out tend to be as long as she is tall.
* StalkerWithACrush: After Rupa told her he would marry Lum, Carla began chasing him around to blast him with her bazooka while shouting out her love for him. No matter how far he ran, she would find him and attack him again.
* UnwittingInstigatorOfDoom: She offers the Moroboshi household some Dark World mushrooms that grow explosively when exposed to heat and light, causing the city to become rapidly overgrown with them and potentially nearly smothering the world with them. This directly leads to Lum's challenging Ataru to a second game of tag, with the continued presence of the aliens on Earth and all their memories of them as the stakes, in exchange for getting rid of the mushrooms.
* WhiteHairBlackHeart: She's a murderously possessive {{Yandere}} with white hair.
* WomanScorned: She was in sort of a relationship with Rupa when they were kids, since he told her he loved her (albeit under Carla's violent threats). Then he told her his great-grandfather had already chosen Lum as his fiancée and Carla went ''ballistic''. For the following years, she has attacked him and almost killed him constantly.
* {{Yandere}}: She used to be Rupa's childhood friend with a crush on him. After he told her he was engaged to Lum, Carla has spent most of her life chasing him, violently assaulting him, and trying to kill him for not returning her affections.

* GoOutWithASmile: After she watches the fireworks with Ataru, Nozomi no longer has any regrets and passes on to the afterlife with a smile.
* LovingAShadow: She watched Ataru running to school from her hospital window every day. Since he seemed energetic and enjoying his life, Nozomi created an idealized version of Ataru in her mind and fell in love with him without knowing his heavily flawed personality.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/nagisa_fpc.png]]

Nagisa's father, a kind-hearted man but a terrible businessman who ate himself to death trying to perfect a recipe for sea urchin-flavored kakigori (shaved ice). He somehow arranges for his former property to be sold to his old friend, Mr. Fujinami, for 300 yen, in hopes of attaining spiritual peace.

* BackForTheDead: He only appears in the two-parter "Nagisa's Fiance" manga arc in chapters 341-342 (and the {{OAV}} adaptation of said arc). At its climax, as the sun rises, he returns to the afterlife, saying that with his "daughter's" reunion with her "fiance" Ryuunosuke, he can now pass on with no regrets.
* BelievingTheirOwnLies: He describes Nagisa as a "late-blooming girl" after Nagisa shows off his bare, masculine chest to Ryuunosuke.
* CordonBleughChef: When he was alive, he tried making sea urchin-flavored kakigori (shaved ice). However, every time he tried it, the result was disgusting and he died alongside Nagisa because of his futile efforts to at least make it edible.
* DeathByGluttony: He died after eating his 98th successive bowl of kakigori.
* DetrimentalDetermination: He literally ate himself to death trying to come up with a recipe for sea urchin-flavored kakigori (shaved ice) that ''didn't'' taste disgusting.
* {{Foil}}: To Mr. Fujinami. They're both stupidly incompetent businessmen and [[RaisedAsTheOppositeGender forced an opposite gender identity on their children from birth]]. However, they're starkly different in their personalities since despite his faults as a breadwinner and father, Mr. Shiowatari is a decent and good-hearted person who truly wishes for his child's happiness, as opposed to Mr. Fujinami being an [[AbusiveParents abusive]] {{Jerkass}} who actively tries to foil his daughter's attempts to do what she wants.
* FriendlyGhost: He's a ghost by the time of his first appearance, but still friendlier than most of the living characters in the cast.
* GoodParents: He's the complete opposite of his buddy Mr. Fujinami in that he's shown to be a loving, gentle, and caring father, delusions aside. Nagisa absolutely dotes on him, and he's even willing to give up the chance to be restored to life to let his "daughter" be revived instead. He even passes on to the afterlife at peace once Nagisa is revived and given a chance to find love with Ryuunosuke.
* IRejectYourReality: He's in complete denial that his son Nagisa isn't a daughter.
* IncompetenceInc: He was a nice guy, but a ''lousy'' businessman. For starters, he thought a deserted island four miles offshore from the nearest beachside town would be a great place to set up a beach cafe. Then he decided he needed a gimmick to lure the customers in... and decided on sea urchin-flavored kakigori, a dish nobody except maybe an alien would find appetizing.
* ThePrankster: His first appearance has him pulling a practical joke on the Fujinamis, Ataru, Lum, Shutaro and Shinobu, and Nagisa comments on his love of pranks.
* StrangeMindsThinkAlike: He shares similarly terrible business sense with Mr. Fujinami, and likewise his delusions about his offspring's gender.
* UnnamedParent: As it's the norm for the parents in this series, his name isn't mentioned and he's only known as "Nagisa's father".
* WantedASonInstead: Gender-flipped. He wanted a ''daughter'' so badly that he decided to bring up his son as a girl.

A spirit that creates dreams. Unfortunately, most of his pleasant dreams lead to conquest and ruin. Originally a one-shot, non-antagonistic side-character in a single chapter, he made a surprise return as the villain of ''[[Recap/UruseiYatsuraBeautifulDreamer Beautiful Dreamer]]''.
----
* AffablyEvil: He is a genuinely affable spirit that takes the form of a short and squat old man. That being said, he does have a temper and Ataru triggers it.
* AntiVillain: [[spoiler:He starts out just wanting to give Lum perfect happiness. However, everyone else is roped into her dream as well, and things quickly start to go OffTheRails.]]
* ArcVillain: He's the main antagonist of the second movie ''Beautiful Dreamer''.
* DreamWeaver: His powers revolve around creating dreams.
* LetsGetDangerous: He's mostly having fun toying with the cast [[spoiler:until Ataru sets him off and he starts using his powers to turn Ataru into even more of a CosmicPlaything than usual.]]
* MakingASplash: One of his reality-warping abilities is to create water, which he does [[spoiler:to trap Mendou and Sakura.]]
* NotSoDifferentRemark: [[CasanovaWannabe Ataru]] calls him an old pervert after Mujaki claims Ataru doesn't deserve Lum's heart. This absolutely infuriates Mujaki.
* ObliviouslyEvil: Sakura calls him out on giving great dictators and warlords inspirational dreams. Mujaki counters that all he gives ''everyone'' pleasant dreams, and it was them and them alone who chose to do horrific things with that inspiration, things that horrified and upset him to the point he wants to retire.
* RealityWarper: Like many dream weavers, he has endless power at his disposal in the dream world and makes great use of it.
* SecretlySelfish: Ataru accuses him of just trying to have Lum all to himself, calling him an old pervert. The accusation drives Mujaki into a rage.
* ShapeshiftingSeducer: [[spoiler:He disguises himself as Ataru, intending to replace him in Lum's dream after he gets frustrated at how callously Ataru treats her.]]
* TakenForGranite: One of his powers is to turn anyone who opposes him into stone statues. [[spoiler:He uses this ability on Cherry, Onsen-mark, Shinobu, and Ryuunosuke to keep them from disrupting the dream he's running.]]

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/kokerupc.png]]

The son of Ataru and Shinobu in a possible future.
----
* AdaptationalLateAppearance: In the manga, he appears in an early story where Ataru and Lum travel to the future. The anime has him appear until the Inaba story arc, which is one of the last arcs of the series.
* DirtyKid: Despite his young age, he's just as perverted as his dad. He gropes Lum's bosom and flips up a female toddler's skirt.
* KidFromTheFuture: He's born to Ataru and Shinobu in the future where they get married.
* StrongFamilyResemblance: He looks identical to his father Ataru, but with Shinobu's hair bangs.

* BizarreSexualDimorphism: Males of her people look like bipedal crows that are a few inches tall and have beards when they're older. Kurama looks nearly identical to human women. That said, it's shown there are female karasutengu who look just like the males serving her --anthropomorphic tiny crows.

* AccentSlipUp: Whenever she drops the {{Kawaiiko}} act, she slips into a Kansai accent since that's the dialect used by aliens from Lum's planet.

* BigBeautifulWoman: Downplayed. She has a slightly thicker build than any of the other mainstay alien girls. In the 1980s anime, this modest bulk would harden into outright muscle when she was angered whilst in her more revealing outfits or in a state of undress.

* ClingyJealousGirl: She goes crazy mad when someone "steals" Rei from her. Or does something that makes her ''think'' they're getting in the way of her relationship with Rei.

* TheDreaded: {{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.

* TheFakeCutie: She deliberately styles herself as a sugary sweet {{Kawaiiko}}, but her real personality is anything but innocent.

* TheFriendNobodyLikes: 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 like Ran, and they make it clear that they're watching her when they interact with each other.

* WrongGenreSavvy: Given that Lum "stole" Rei in the past by getting engaged, Ran frequently accuses Lum of wanting to do it again despite Lum's many assertions that she's devoted to Ataru now.
* {{Yandere}}: She's hell-bent on keeping 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.

* AbhorrentAdmirer: To Lum. Rei looks handsome in his humanoid form, but he often changes into an ''ushitora'', which is one of the reasons why Lum broke up with him. That he's a mindless eating machine also repulses her; one story notes that when Lum got him a locket as a symbol of her love, he ''ate it'', sending her away in tears.

* EveryoneHasStandards: Kurama draws the line at forcibly chaging someone's gender, and was ''not'' amused when she discovered Ryunosuke was a girl and the Karasutengu were trying to turn her into a boy.

* HateSink: She has little to no characterization aside from being Ran's AbusiveMom who traumatized her daughter into becoming a phycho and contributing to the latter's resentment towards Lum.

* BullyingADragon: They try to pick up a fight with [[BadassBiker Benten]], [[ShockAndAwe Lum]], and [[AnIcePerson Oyuki]], despite their reputation making each of them known as a force to be reckoned with. Even the Spice Girls know they're screwed if Benten's "gang" gets serious against them.

* EvilCounterpart: Whilst Elle could be considered an EvilCounterpart to both Ataru and Lum, it's a case of a ZigzaggingTrope:
** Like Lum, Elle is a beautiful AlienPrincess who wishes to claim Ataru as her husband because [[AccidentalMarriage he beat her in a game of tag]]. [[spoiler:With the difference that it turns out that Ataru actually ''lied'' about beating Elle.]] Both, in fact, do or have done awful things in the name of forcing Ataru to love them back; Lum even drags Ataru into her ship with plans to force him to marry her and move to Oniboshi at the start of the film, which isn't very different to Elle literally dragging Ataru to the altar in chains at the film's climax. But Lum is one hundred percent committed with Ataru and Ataru alone. Elle, on the other hand, has amassed a thousands-strong "harem" of handsome men by seducing them and then cryogenically freezing them, but hypocritically claims to only love Ataru alone... despite still maintaining her "collection".
** Ataru and Elle are both lusty pursuers of the opposite sex, but Ataru is open about being a HaremSeeker, whilst Elle is a hypocrite, and Ataru would never ''force'' a woman to join his harem, and Elle has no shame about cryo-freezing her would-be suitors, treating them more like trophies than Ataru ever would.,

The antagonist from the first movie, ''Only You''. She is the lovely ruler of planet Elle.

* EvilCounterpart: To Lum. Elle is also an attractive AlienPrincess who lost to Ataru in a game of tag [[spoiler:(although he merely tricked her)]] and wants to claim him as her husband for it. However, Elle is ''far'' worse than Lum ever could be because she keeps a collection of frozen handsome men and is determined to make Ataru hers even if she has to turn him into her slave.

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

* AmbiguouslyHuman: Inaba appears to be a human boy in a bunny-suit that allows him to enter subspace, but if he IS human then no backstory is ever given as to how he came to work at the Bureau given that all the other workers are anthropomorphic rabbits.
* BecauseYouWereNiceToMe: He ends up falling in love with Shinobu after she finds him passed out and hungry in the street and gives him some food.

* SatelliteLoveInterest: He's introduced very late into the series and his only characterization is being a NiceGuy who loves Shinobu, with all of his appearances being about his relationship with her.

->Voiced by: Kaneta Kimotsuki (JP, original series), Koichi Sakaguchi (JP, ''All-Stars'')

* BerserkButton: She'll deliver DisproportionateRetribution to anyone who steals Rei from her. Or does something that makes her ''think'' they're getting in the way of her relationship with Rei. Also, Lum's mere presence usually is enough to send her into psycho mode.

* ClingyJealousGirl: She absolutely won't forgive anyone who "steals" Rei away from her.

* ReallySevenHundredYearsOld: 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.

->Voiced by: Kaneta Kimotsuki (JP, original series)

A spirit that creates dreams. Unfortunately, most of his pleasant dreams lead to conquest and ruin. Seeking fulfilment before he retires from making dreams for good, [[spoiler:he became smitten with Lum and wants to make her happy.]]

* ArcVillain: Of ''Beautiful Dreamer''.

* MakingASplash: One his reality-warping abilities is to create water, which he does [[spoiler:to trap Mendou and Sakura.]]
* NotEvilJustMisunderstood: Sakura calls him out on giving great dictators and warlords inspirational dreams. Mujaki counters that all he gives ''everyone'' pleasant dreams, and it was them and them alone who chose to do horrific things with that inspiration, things that horrified and upset him to the point he wants to retire.

* VoluntaryShapeshifter: [[spoiler:He disguises himself as Ataru, intending to replace him in Lum's dream after he gets frustrated at how callously Ataru treats her.]]

->Voiced by: Masako Sugaya (JP, original series), Creator/RieKugimiya (JP, ''All-Stars'')

->Voiced by: Matsumi Oshiro (JP, original series)

* BrattyHalfPint: 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 almost always supports him, though on rare occasions even she will get sick of him.

* CatchPhrase: "I'm a good boy!"

* CatchPhrase: "Ran-chan is sooo happy!"

* CatchPhrase: "Lum!" and "Food!" are the main words that come out of his mouth. "Ran!" starts coming up later, though.

* CatchPhrase: She screams "FIRE!!" whenever anyone rings a firebell, followed by her rushing to put out the flames.

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.

* AccompliceByInaction: In her school days, Oyuki never joined Benten and Lum when they bullied or picked fights with other students, but she acted like a disinterested bystander through all of her friends' mischief. As a result, she got labeled as a delinquent too, much to her dismay. That said, their teacher CA0-2 has a higher opinion of Oyuki than he does of the other girls in the 1981 anime.

* TakenForGranite: One of his powers is to turn anyone who opposes him into stone statues. [[spoiler:He uses this ability on Cherry and Ryuunosuke to keep them from disrupting the dream he's running.]]
