Hikaru Gosunkugi (五寸釘 光, Gosunkugi Hikaru)
A creepy, reclusive, unpopular, nerdy sort of boy who has a deep crush on Akane, which she is unaware of, evidently because she was nice to him. Fixated on black magic, but totally inept at it; far more likely to hit his thumb when trying to perform Ushi no Koku Mairi (a Japanese cursing ritual) than make it actually work. He even got himself struck by lightning once in the anime, after apparently managing to call a storm to school successfully. In the manga, he's a pathetic member of Akane's class, ignored by just about everyone, while in the anime he's an equally pathetic transfer student introduced in the sixth season.
- Black Magic: He wants to master this and use it to get rid of his rivals for Akane's hand, most notably Ranma, but it basically never works. On the other hand, the one time that he actually got his hand on real magic (the control paper dolls), he only used it to mildly embarrass Ranma through a pratfall, so it is very questionable if he is really ruthless, or just doing harmless venting, in the same way many others use fighting games.
- Butt-Monkey: Unlucky in basically all his appearances. So unlucky, in fact, that most of his appearances in the anime are gone. (Often replaced with the anime-only character Sasuke.) He does get to make an appearance in the SNES Ranma ½: Hard Battle game, though.
- Camera Fiend: Takes pictures of Akane whenever he can, in the manga took pictures of Ranma while trying to learn something to use against Ranma (failed since Ranma could sense where he was at all times), and also took one of the photos Kodachi altered in that canon.
- Demoted to Extra: He appears very late in the anime series and most of his roles in the earlier part of the manga were taken over by Sasuke or other one-shot filler characters.
- Dogged Nice Guy: To Akane, for a while.
- Hollywood Voodoo: Actually, averted. While the various rituals and spells he performs look a lot like Hollywood Voodoo to Westerners, to the extent that it's the source of his Fan Nickname, they are actually all 100% authentic Japanese mysticism. The habit of wandering around with lit candles strapped to his head is from Shinto; they're supposed to help him see ghosts and into the spirit world. The little straw fetishes he's always driving nails into are from a cursing ritual called "Ushi no Koku Mairi", which is actually illegal in Japan.
- Loners Are Freaks: A chicken and egg trope here; is he left alone because he's such a freaky little guy, or is he such a freaky little guy because nobody wants to be his friend?
- Looks Like Cesare: The pallor, tightly drawn skin and circles under his eyes are part of what defines him as "the class creep", adding to his spooky mine. Amazingly, they're hereditary; both of his parents look the same.
- Nightmare Fetishist: Perhaps more so in the anime than in the manga; even beyond his cursing ritual obsession, he's a fanatic for gathering grimoires of black magic (especially those focuses on cursing), thinks that taking a girl to a purportedly haunted graveyard and telling her about various methods of inflicting curses on people you don't like are romantic dates, and his only problem when he realised his girlfriend was a ghost was the fact that if he got serious with her, he'd have to give up on Akane.
- Paper-Thin Disguise: In a episode, Gosunkugi dressed himself up as Ranma and began committing lame crimes against schoolgirls at night in order to ruin his reputation. Somehow, he managed to fool the entire school. Obviously, he didn't fool the REAL Ranma, who encountered him in his girl form.
- Powered Armor: In the manga, buys a "Warsuit" that latches onto Ranma's wrist to power up. However, this Ranma-level suit was designed with three major limits to prevent misuse: once assembled and worn, it can't even move unless latched onto the primary target; once engaged, the user MUST land a punch on the target within a time limit, or the suit will self-destruct; if the user successfully lands a punch, the suit will deactivate and fall apart. Since its advertised as a weapon against bullies, it's an intelligent method of self-control.
- Stalker with a Crush: Takes photographs of Akane working out during gym class, but in both canons she doesn't really notice him given he's so low-key and subtle compared to the flamboyant and much more vivid Kuno and (somewhat) Ryoga. Sneaking around in her backyard taking photos of her or staking out her jogging route kind of fall into second place compared to attacking her with a sword in front of school every morning while bellowing declarations of love.
- Thinks Like a Romance Novel: He tends to daydream along the lines of Romance Sitcoms whenever he thinks about Akane.
- Ungrateful Bastard: Gosunkugi gets cornered and beaten up by delinquents, and Ranma jumps in to save him. How does Gosunkugi thank him? By ordering a special mechsuit to use to beat Ranma. How justified you find this depends on whether you read the original manga (more accurately, the fan translation thereof) or the officially translated version by Viz. In the former, Ranma says something along the lines of "it's the duty of a martial artist to help the weak and downtrodden!", and it's the second part that sets off Gosunkugi's pride. The Viz translation has Ranma go "As if there could be a thing like you without embarrassment, Gosunkugi!" — he says it with the same blithe, well-meaning look on his face, but worded like that, it's really hard to see Ranma as not deliberately adding insult to (near) injury.
Tofu Ono (小乃 東風, Ono Tōfū)
A minor character introduced as the local chiropractor and acupuncturist, who has tended to Akane's injuries since she was a little girl, which caused her to develop a Precocious Crush on him. Fixated on Kasumi, turning into a bumbling idiot whenever he hears her voice or even sees a photo of her, never mind actually seeing her. Dropped from the manga by the end of the Full Body Cat's Tongue Pressure Points story, making one final appearance at the very beginning of the Moxibustion arc, but remains a minor fixture of the anime.
- Amazingly Embarrassing Parents: In the anime version exclusively. Tofu's mother is his only living parent, but she's crazy enough to make up for his deceased father. She never goes anywhere without a family shrine strapped to her back to honor Tofu's deceased father, and that's the least weird thing about her. She's absolutely obsessed with grandchildren, and because of that she's obsessed with big-hipped women, as she believes big hips on a woman will naturally result in lots of healthy children — she even announces her wish for her son to marry a huge-hipped, incredibly gonky female wrestler because of the woman's mighty hips (that the woman had released a country music song called "The Big Hips Blues" didn't hurt), and will spontaneously grab women's hips and fondle them in order to see if they might be a good match for her son. And if he says something that disagrees with her even the slightest, no matter how gently he puts it, she will attempt to guilt him into compliance by dramatically threatening to commit suicide.
- Big Brother Mentor: To Akane, which is the basis of her crush on him.
- Butt-Monkey: Downplayed, but the anime's version of the character is often used for comedy in how things tend to go wrong for him. The anime's very first filler episode revolves around him being visited and humiliated by his crazy mother, including being robbed of a good amount of money by Nabiki Tendo. Then there's the episode where he tries to take Kasumi on a date at an amusement park... only for the rest of the Tendo Household and all of Ranma's fiancees and rivals to tag along with them, so he never gets the chance to do anything romantic with her.
- Chuck Cunningham Syndrome: He vanishes without a word once Cologne takes his place as official font of obscure wisdom. He shows up from time to time in filler episodes late in the anime, but his plot importance was gone by the end of Season 2. In the manga, after volume 12 he's gone for good.
- Dogged Nice Guy: Tofu is never anything other but sweet and chastely affectionate for Kasumi, but she never returns his feelings. In fact, it's subtly implied by canon that she's not even aware that he is in love with her!
- Informed Ability: We're told he's a strong and skilled martial artist, but we never see him do anything other than manipulate pressure points, and then for health purposes. Downplayed in the anime, where a seventh season episode seems him subdue a good number of the Frog Hermit's knife-wielding attack frogs]] with a flurry of rapid-fire paralytic pressure point touches... only to then be reduced to a catatonic, mumbling imbecile when presented with a picture of Kasumi.
- In the Blood: In the anime's first season, a filler episode states that Dr. Tofu's father, Mr. Ono, used to get just as love-drunk around Mrs. Ono as Dr. Tofu gets around Kasumi.
- Love Makes You Crazy: Dr. Tofu's most famous trait is that whenever he sees or hears Kasumi, he's so overwhelmed by his romantic feelings for her that he turns into a bumbling imbecile, prone to babbling like a fool, losing track of where he is or who people are, and doing strange, nonsensical things. Just how bad it is depends on how they interacted; just hearing her on the phone can leave him a little mixed up for a few moments, whilst in face-to-face meetings, he gets extremely mixed up. A compliment or a touch from her can result in him doing things like running through the streets and dancing with his model skeleton.
- Love Makes You Dumb: When Dr. Tofu goes into love-crazed mode, he's a legitimate danger to himself and everyone around him, to the point that his clients all know to reschedule appointments if Kasumi's been nearby, as he could seriously hurt them. And the there's the infamous moment during the Memory-Sapping Shampoo story where he insists on dropping by with the vital notebook needed to cure Akane's amnesia... and then promptly starts shredding it into pieces when Kasumi speaks to him.
- MayDecember Romance: Invoked. Dr. Tofu is deeply infatuated with Kasumi, despite the age gap between them - she's only 19, whilst his age is never specified, but reasonably he's somewhere in his late 20s to early 30s.
- Not So Above It All: Normally, he's one of the most normal characters in the series. When Kasumi's around, on the other hand...
- There's also the fact he's named his model skeleton "Betty", and likes to play little pranks on people with her.
- Oblivious to Love: He's seemingly unaware of Akane's crush on him, which is ironic, given the implications that Kasumi is likewise completely oblivious to his crush on her.
- Only Sane Man: Putting his issues with Kasumi aside (well, well aside), he's the most down-to-earth, intelligent, well-adjusted, and observant character in the series. In stories where Kasumi doesn't figure, he's a major asset and invaluable support to Ranma and Akane, and the community loves him.
- Scary Shiny Glasses: In both anime and manga, his glasses, usually clear, flash and instantly fog up whenever he spots Kasumi, and they stay that way until his love madness recedes (which might be long after Kasumi has gone).
- Shipper on Deck: Works very subtly to get Ranma and Akane together, even if it means inflicting a temporary disability on the former to make the latter's caring side come out.
- Strong Family Resemblance: According to the anime, Dr. Tofu's deceased father looked exactly like him when he was younger, and his portrait in the family shrine that his wife still carts around from place to place is literally "Dr. Tofu with a triangular mustache".
- Will They or Won't They?: There's a fair bit of Ship Tease between the two in both anime and manga, but Tofu Cannot Spit It Out and Kasumi remains Oblivious to Love.
Nodoka Saotome (早乙女 のどか, Saotome Nodoka)
Ranma's long-absent mother is a late-comer to the series. Back when Ranma was just an infant that had yet to learn how to walk, his father took him away from home, assuaging Nodoka's complaints by vowing he and Ranma would commit Seppuku if he failed to make Ranma a "man among men". After Ranma's little accident at Jusenkyo, Genma decided it would be best to avoid Nodoka, though she eventually did find out — fortunately for her son and husband, the precise event had Ranma at some of his best behavior and she decided that the curse wasn't grounds to make Ranma kill himself. Generally a very sweet and motherly sort, but she is just as fixated on honor as her son and husband are (perhaps more so), and she's still carrying that sword around by the series' end, watching and judging Ranma's behavior...
- Abusive Mom: While Played for Laughs almost as much as her husband is, she's just as bad, if not worse. Despite the fact that the contract consists of a verbal vow ("I will make Ranma a man among men") and a written seal ("I will commit Seppuku: Genma, Ranma"), both of which are incredibly vague, she is totally willing to call it in if she ever judges Ranma to somehow be unmanly. Nodoka is so fixated on the idea that whenever she visits looking for Ranma, she keeps a sword in constant reach, in preparation for the decapitating strike she will be called on to use in the ceremony. In fact, she seems to have the swordswoman's equivalent of an itchy trigger finger, being quite willing to draw it at the slightest hint that her son is being unmanly (both before and after finally meeting him,) and going all the way to donning the requisite regalia if he does something very unmanly. She doesn't get many appearances in the series once she moves into the Tendo Dojo, though, so this aspect is somewhat glossed over.
- Cute Clumsy Girl: Don't stand near her if she draws her sword. Or if she sits on a "DO NOT SIT" water valve.
- The Dreaded: Played for Laughs. Among the few non-villainous examples in media, she invokes fear in Genma and Ranma like nobody's business, before and even after they finally reveal themselves.
- The Fettered: She holds fast to, and takes pride in, her honor as "a warrior's wife". Thus, she's frequently believed to cling so tightly to the contract in order to draw the emotional strength from it she needs to survive being separated from her son and husband for so many years. And then there's the secondary task she's meant to perform if forced to fulfill the seppuku promise.
- Additionally, the infamous "seppuku promise" doesn't involve just her honor, but Genma and Ranma's honor too. While they themselves may have little use for it at present time, and in fact stomp all over it more often than not, Nodoka is bound to uphold her husband and son's honor, and hold them up to it, whether she likes it or not. So her insistence on carrying a sword "just in case" is less a case of her being abusive and more being put on the spot by Genma's ill-conceived conditions.
- Honor Before Reason: She will hold Ranma to the contract Genma wrote up come hell or high water, despite the fact it is so vague it is impossible to truly determine what would actually fulfill it successfully. Furthermore, she will commit ritual suicide herself after fulfilling that task, according to family honor. She does partially avert the trope when she declares that Ranma's Nyannniichuan curse does not merit an automatic failure to live up to the contract, due to the sheer heroism of the way he saved her despite exposing it to her in the process.
- Iconic Item: The Saotome Family Sword. Wrapped in a bundle, sheathed, or live, it's pretty much glued to her hand.
- Kimono Is Traditional: Nodoka the Yamato Nadeshiko wears one at any given time.
- Mama Bear: Tries to protect Akane and Ranma with everything she has, if she thinks they're being threatened.
- Missing Mom: So much that Ranma didn't even remember her prior meeting her.
- Parents as People: What saves her from being a downright abuser is that the poor woman does love Ranma as much as her seriously warped nature allows, as seen in Mama Bear. She also spent some time sewing a customized winter coat for Ranma when he was still a baby in expectation that he'd wear it some day. Before she found out the truth, she doted on, cared for, and worried about "Ranko" just as much as a mother would, becoming seriously distressed when she thought the girl was in trouble. And as stated in Mama Bear above, she's absolutely devoted to Akane as well—when under the impression that a "molester" was stalking Ranko and Akane, Nodoka hid herself in the Tendo home without telling anyone, just so she could keep an eye on them and spring on the stalker at a moment's notice (the fact that even she couldn't pull so many all-nighters without falling asleep from exhaustion, but ''still' appeared immediately when needed, only humanizes her further.)
- Perpetual Poverty: Her prior, "poor" house was demolished and she had to move to another one, and has to recycle martial arts scrolls just to have paper to make envelopes. Ranma says she's the model wife of a poor martial artist. Even more so after the Fiancee Brigade (Shampoo, Kodachi, and Ukyo) destroyed her house due to a misunderstanding.
- The Pollyanna: Even though her situation would give anyone soul-crushing despair, she's always cheerful and optimistic during her visits, and is more than happy to help around the house or completely spoil "Ranko".
- Principles Zealot: She is so fixated on the concept of a "Man among Men" that she lets Genma take a toddler Ranma away, despite literally fighting against it tooth and nail just moments before, all because Genma provided a two-part promise. Verbal: "I will make Ranma a man among men." Written: "I will commmit seppuku." While it's all fine and dandy, both ethically and legally, for Genma to sign such a contract, making an infant who can't read or write "sign" by inking his hand and slapping it on the paper goes beyond the pale, even in the most "conservative" of Japanese homes. Thus, by Nodoka's understanding, if Genma was so utterly dedicated to this goal as to go that far, she had no choice but follow both sides of the contract to the letter. Fortunately, she decided that, curse or no curse, Ranma was a man through and through no matter what body he's in —it's "only" if his personal behavior proves otherwise that she starts pulling out her sword.
- Shipper on Deck: Not as bad as her husband Genma, but she takes it as granted that Akane and Ranma are engaged and is excited to hear what Akane thinks of her son, and is all too happy to help move the relationship along.
- Stepford Smiler: As cheerful as she is whenever she visits the Tendo home, especially when she gets to spend time with "Ranko", she turns sad and lonely as soon as she's out of sight from them, and she tends to be disappointed to find out she "just missed" Ranma and Genma yet again. In a particularly heartbreaking scene, she confesses to Ryu Kumon that she had already figured out he wasn't her real son, but that she enjoyed the deception for a while. However, it's made clear to the reader that, despite her words, losing her son a second time hit her very hard.
- Strong Family Resemblance: Allowing for age and height, the only difference between female Ranma and Nodoka in the anime is hair and eye color. In the manga, there's not even that.
- Supreme Chef: Genma says as much, to which Ranma gets pissed since it reminds him that he's never had his mother's cooking his entire life.
- Took a Level in Badass: As clumsy as she was with her sword at first, later appearances showed a dramatic improvement in skill and confidence. It's never made clear how good she actually is, however.
- Ugly Guy, Hot Wife: It's a mystery how a beautiful woman like her ended up married to a man like Genma, who can be most generously described as "strong-featured". At least we now know where female Ranma got her good looks from.
- Yamato Nadeshiko: Fixated on honor, wears a kimono, carries a katana, and supported herself during the years her husband and son were in their training journey.
Sasuke Sarugakure (猿隠 佐助, Sarugakure Sasuke)
For reasons that will never be known, the anime's creative team decided to drop the minor character Hikaru Gosunkugi, Akane and Ranma's creepy classmate who would sometimes become a reluctant ally or flunky to Tatewaki Kuno. Instead, they decided to create a new character to take the role of Kuno's dedicated servant, and thus was born Sasuke Sarugakure, whose name means something like "Ninja from the Hidden Monkey Village". This ugly midget Ninja is most frequently seen at Tatewaki Kuno's side, but he will also serve "Mistress Kodachi" if she needs his assistance as well. Sasuke serves as something of the Jack-of-all-trades manservant to his masters, doing everything from spying on their enemies/love interests, to cooking their food, to cleaning their house, to making shadow puppets to help them sleep, to helping them train or fighting at their side — it's implied he may have actually been their primary caretaker when they were children. In return, he is rewarded with horrific mistreatment. He is forced to sleep outside in all weathers like an animal, fed only leftover scraps (and that infrequently; he once had to live for ten days on a single bowl of brine, and he's forgotten what milk and watermelons taste like), forced to drink the water from the storm gutters, and frequently beaten and berated by his charges.
- Butt-Monkey: Even more so than Kuno, as he generally doesn't mean any more harm than needing to serve his master and is fairly amiable if not being compelled by that, but he still gets physically abused a lot.
- Canon Foreigner: Created exclusively for the anime.
- Combat Pragmatist: He's a ninja, what were you expecting? He's aware that he's pretty lousy fighter, so he uses traps, ambush tactics, deception, trickery and basically any dirty trick he can come up with to even the odds.
- Fragile Speedster: He's rather fast but sucks at combat, and his ability to take a hit is atrocious. Combined with his clumsiness, Sasuke has a tendency to knock himself out in a fight.
- Happiness in Slavery: Downplayed. Sasuke makes it quite clear that he would like if the Kunos treated him better, but he's a strong believer in the duties of a servant, so he tolerates the abuse and does his best to fulfill their every command.
- Made of Iron: While not very good in combat, he has a tremendous threshold for pain, quite capable of feats like remaining in an exposed mailbox, in the middle of a blistering heatwave, for three whole days with no food or sleep in order to wait for his designated quarry to pass by.
- My Master, Right or Wrong: He's well aware that his masters are insanely abusive and barely capable of feeding themselves without him, yet stays loyal to them and refuses to leave. In the eisode "Les Miserables of the Kuno Estate", he even leaves Akane, whom he had been planning to transfer his loyalty to after being fired by the Kunos, because Tatewaki promised to start treating him better.
- Punch-Clock Villain: Has no problem with Ranma or his relationship with Akane personally, he just becomes antagonistic to them when one of the Kunos orders it.
- Ninja: A parody or subversion as, in a city full of practitioners of Supernatural Martial Arts, he's a clumsy incompetent with minimal fighting skills and armed with basic ninja tricks. He is, however, incredibly fast (able to go from one end of the school gym to the other, help Akane spring over the leaping horse, and then dart back into the shadows where he started from, all without anybody seeing him) and very skilled at the art of camouflage... though not so good with outright disguise.
- Old Retainer: Not that old, but he has worked for Kuno since he was a child.
- There Was a Door: Sasuke once bursts up through a loose panel in the floor to give a report in person.Kuno: I meant through the door, you blithering idiot!
Hinako Ninomiya (二ノ宮 ひな子, Ninomiya Hinako)
The last of the major characters to be introduced (in the manga — the anime was cancelled before she was created, so in that canon she was merely the subject of an OAV and appears in a second one, Nightmare Incense of Spring Sleep). Miss Hinako was hired by Principal Kuno ostensibly as a new Homeroom/English teacher for Ranma's classroom, but, aware of her fame dealing with troublesome students, with the express purpose of having her pacify and discipline his unruly students. Hinako's story begins many years before the series, when she was a little girl in the hospital for an unidentified ailment. Happosai, wandering by, dropped in and either took pity on her, saw someone he could use to help him steal underwear from the nurses, or both. He subjected her to a regime of Pressure Point manipulation that would endow her with the ability to drain the Battle Aura from other people, which he insisted would help her get better. Flash forward to the present day, and she's all better... but now she's stuck looking like a kid unless she drains somebody's Battle Aura, and she'll only remain in her adult form until she uses up the ki she stole. Obsessed with stomping out "delinquency", she frequently clashes with Ranma, particularly after she falls in love with Soun Tendo.
- Achilles' Heel: A simple set of five pressure points hit simultaneously will knock out her powers for an entire day. The two on her back aren't much of a problem, but the three in front are right over her breast - the resulting attack looks a lot like someone's wrestling her into submission and groping the hell out of her.
- Action Girl: Perhaps the second strongest recurring female character (behind Cologne). The only one who can hold her own at Ranma's level, albeit by use of her ki-draining skills as opposed to hand-to-hand combat.
- Aloof Dark-Haired Girl: In her adult form, she is tall, beautiful and acts very aloof and elegant. However, if she stays this way too long, she will revert to her childish personality.
- Aren't You Going to Ravish Me?: During the "Little Hawaii" story, a bunch of male students from Fūrinkan are infected by the "Aloha virus" thanks to the Principal's latest ploy. This makes them act like "honeymooner tourists in Hawaii", the dream of any Japanese. Thus they begin assaulting female Ranma, Akane and Ukyō to make them their "wives"... but they twice ignore Hinako-sensei since she looks like a little girl. She feels quite insulted by that.
- Attention Deficit... Ooh, Shiny!: She takes her role as an educator and disciplinarian VERY seriously, but she's JUST as easily distracted by toys, games, manga, snacks, and generally anything that would capture the attention of a little kid.
- Chronic Hero Syndrome: The biggest case in the series, exceeding even Akane.
- The Ditz: In child form, or after going too long without changing into it, she has an incredibly short attention span and tends to make very poor judgments about the world around her.
- Dual Age Modes: Between "child" and "adult", via the "Happo Go-en Satsu".
- Energy Absorption: One of her two modes of attack, Hinako's "Happo Go-en Satsu" lets her siphon away the ki from active combatants, an act that temporarily renders the victim too weak to stand. It also makes her immune to even the fiercest of Ki Attacks, as the Go-en Satsu lets her simply drink them up. As a bonus, she can release that energy as a blast that will hit like a speeding truck. If an opponent is wise to her absorption technique and refuses to engage, she can still use the "Happo Gojuu-en Satsu" (Fifty Yen as opposed to Five Yen, for extra punch) to suck the ki of anyone in the effect cone, even onlookers and bystanders.
- Genki Girl: In kid form, she acts somewhere between this and The Ditz, being full of energy and constantly running around until she tires herself out.
- Glass Cannon: To anyone who knows her pressure points. However, even Ranma can only do it over the course of a drawn-out battle, given that she can reduce any fighter to a groaning mass with just one shot, and take out a wall with the resulting firepower.
- Hello, Nurse!: Her adult form tends to understandably attract this kind of reaction.
- Hopeless Suitor: Though she falls head-over-heels for Soun Tendo, his daughters and future son-in-law object to the idea and he himself doesn't seem to reciprocate, partially because he's still mourning his first wife.
- Hot Teacher: Her adult (and true) form is an incredibly beautiful and curvaceous woman, which is an instant target of lustful admiration from her male students.
- Kamehame Hadoken: After she drains ki, she can launch it as a massive blast of ball lightning via her Happo Tsurisen-Gaeshi technique. Using this move expels all of the ki she drained beforehand, which shrinks her back to a child, but the blast usually instantly defeats her opponent if it hits.
- Likes Older Men: While vague, her true age is somewhere in her early twenties, yet she falls in love with Soun, who is anywhere between very late 30s or mid-40s. This is naturally much more pronounced when she regresses to her "little girl" form. Unfortunately for her, Soun only acknowledges her strictly as a teacher when adult, and as nothing more than a child and friend of Akane's otherwise.
- Littlest Cancer Patient: She was one of these until Happosai "cured" her.
- Magic Pants: Her favored one-piece yellow dress was specifically chosen to fit both her child and adult forms. It's just Stripperiffically short-skirted and low-necked on her adult form.note
- The Mind Is a Plaything of the Body: Under normal circumstances, her personality definitely changes whether she's an adult or a child, with the former being stern, serious and seductive, and the latter being a lazy, childish goofball. However, being stuck as a little girl has affected her so much that, if she stays too long in her "real" adult mode, though, her mind will wander and she'll start acting like a kid again.
- Ms. Fanservice: Her adult form. Her yellow dress manages to fit both her child and adult forms, but just so for the latter, resulting in a short skirt and a low neckline (and her adult form sure does fill it).
- Older Alter Ego: Inverted. She's Older Than She Looks - in her twenties - but can only appear thus after draining battle aura. Most of the time she's pre-teen.
- Phlebotinum Overload: Absorbing too much energy, whether accidentally or as a controlled, deliberate action, will lead to this. If controlled, she uses a source of endless battle ki to remain in adult form as long as she can, allowing her to fire off ki blasts as often as she pleases without reverting to child mode... but her mind will eventually drift back to a childish personality and break down even further to a point she absolutely cannot maintain focus at all (where she's otherwise implied to be a competent teacher even in child mode.) But when she accidentally drained the angry, vindictive energy of all the students previously humiliated by the Principal, she became an engine of destruction bent on exacting revenge on him come hell or high water, and it took several, extraordinarily powerful ki blasts (and actually hitting him with the last one) for her to vent all that burning rage and change back to normal.
- Punny Name: Her ki-draining attacks are called the "Happo Go-en Satsu" and "Gojuu-en Satsu", for the five- and fifty-yen coins she uses as a medium. When she gives back the collected ki as a projectile? "Happo Tsurisen-Gaeshi", or "Change-Return". In the English, these are named the "Happo (Number)-Yen Satsu" and "Happo No-Yen Coin Return" instead.
- Rapunzel Hair: Her hair reaches down to her hips.
- Sensei-chan: When she's a kid, she acts more childish than her own students, goofing off, staring into space, sleeping at her desk...
- Soap Opera Disease: She had a "weak constitution" as a child, complete with IV and adorable cough. She got better thanks to Happosai's treatments, which also turned her into a chi-vampire.
- Sweet Tooth: When in child form, her obsession with sweets rivals or exceeds Ranma's.
- Unskilled, but Strong: Hinako has absolutely no fighting skills, having never trained a day in her life. Get close enough to pin down her hands, and she can't retaliate. But you have to get close enough first, which is a huge feat in and of itself, given that her potent ki-drain and ki-blast combo techniques allow her to flatten virtually everybody that goes up against her.
- Who Will Bell the Cat?: If her pressure points were to be hit every day consecutively for a month, she'd permanently lose her ability to drain battle aura. However, Ranma is the only one capable of doing so (Happosai's more than skilled enough, but his armspan is too short to hit all five at once), and the first time he pulled it off required a drawn-out battle he spent several days recovering from and which practically destroyed his reputation, as everybody thought he was trying to molest her. Understandably, Ranma promptly said "nuts to that" and contented himself with just living with her and exploiting her mental weaknesses to keep her out of his hair.
- World's Strongest Man: Thanks to her ki-manipulating abilities, Hinako is flat-out one of the strongest opponents Ranma goes up against, up there with the likes of Herb and adult Saffron. Her unique ability to siphon off an opponent's fighting energies and return it to them in a deadly energy blast makes a frontal attack effectively impossible; only someone who can out-think her can beat her.
Maomolin (猫魔鈴, Maomōrin)
A giant bareneko (ghostly cat) that Shampoo accidentally brought back to Nerima from a visit to China, Maomolin wants to claim a human wife and will do anything to get one.
- Grand Theft Me: Possessing people is his primary spiritual power. It never does any good as he's a terrible actor, he can be exorcised just by hitting whoever has possessed him, and he tends to choose people that whoever he's fighting would have no problems hitting. Like when he possessed Genma to try and escape the wrath of Ranma.
- Interspecies Romance: Despite the fact he's a cat, he's fixated on taking a human wife.
- I Owe You My Life: In the anime, Ryoga saves him from a pack of dogs, so Maomolin offers to grant Ryoga a wish, declaring he is also a guy and must repay such a debt. Upon hearing about his shyness and how this interferes with his desire to court Akane, he possesses Ryoga and proposes for him.
- Meganeko: He's a cat the size of a grizzly bear.
- Obake: He's the ghost of a cat from China, able to steal bodies and lay curses on people, and is most commonly identified as a "bakeneko" (literally "ghost cat").
Akari Unryu (雲竜 あかり, Unryū Akari)
A sweet, gentle girl who shows up very late into the manga. Heir to the Unryu farm of Sumo Wrestling Pigs, she rides around on her hand-reared Yokozuna Pig, Katsunishiki, seeking a man strong enough to defeat him. This is the only man she will be allowed to marry. When Ryoga succeeds, she instantly falls in love with him, and he quickly becomes attracted to her in return. After her introduction she featured in one more arc before the end of the manga and did not appear at all in the anime.
- Best Her to Bed Her: A variant, in that in her instance, it's her giant sumo pig whom her suitors must defeat.
- Beta Couple: With Ryoga. They are the only couple in the series with a functional relationship and the only one to get a nearly definite happy ending.
- Brooding Boy, Gentle Girl: Gentle Girl to Ryoga's Brooding Boy.
- Compliment Backfire: Akari loves pigs and complimented Ryoga repeatedly by comparing him to a pig. He did not see this as a compliment, in part because he turns into a pig.
- Expy: A nearly identical character, a farmer's daughter with Super Strength called Anna, shows up in the anime. While you'd think the manga was first, the filler episode with Anna (called; "Ryoga, Run into the Sunset") came first.
- Innocently Insensitive: She seriously thinks that comparing someone to a pig is a compliment.
- Kid with the Leash: She usually traipses around Japan riding an ENORMOUS yokozuna --sumo champion-- pig who will attack any man in their way.
- Love Martyr: Believing Ryoga hates pigs, Akari decides to make herself hate them too by having Katsunishiki attack her for an entire week. It fails since she can't bring herself to hate pigs.
- Multicolored Hair: Takahashi's watercolors consistently depict her with forest-green hair and a pink Skunk Stripe.
- Nice Girl: One of the few genuine nice characters in the series. Akari is incredibly sweet, polite and patient. If you get thrown off by her calling you a pig, don't worry, she means it as a compliment.
- Satellite Love Interest: Her personality and appearances in the story are centered around her relationship with Ryoga. She only exists to give Ryoga a happy ending.
- Second Love: For Ryoga, although he still spends some time pining after Akane. By the end of the manga, Ryoga seems to be completely over Akane and is focused on his relationship with Akari.
- Skunk Stripe: She has a lock of lighter hair in both sides of her otherwise dark hair.
- Twice Shy: With Ryoga.
- Yamato Nadeshiko: A sweet, determined, and devoted Japanese girl who comes from a long family line of sumo...pig farmers.
A male ninja raised as a female kunoichi (a female ninja) by his cruel and hideously ugly stepmother and stepsisters. Despite Konatsu being a prodigy in the arts of ninjitsu, he never managed to kill off his stepfamily (not through lack of trying) and was resolved to being their slave. Until the day Happosai, Soun and Genma wandered into the "Sexy Ninja/Red Hot Kunoichi Teashop" and, horrified by the fact the "sexy ninjas" were his stepfamily, destroyed it, whereupon they sent him for revenge upon Ranma. Konatsu decided he'd rather stay in Nerima, particularly after Ukyo treated him kindly and unintentionally caused him to fall in love with her, and began working at Ucchan's Okonomiyaki after his stepfamily was driven away with the help of Ukyo, Ranma and Akane. Though Ukyo still treats him in a way anyone else would consider ridiculously shabby, it's much more than he had at home and so he's content with it. The last main cast member to be introduced to the series, and the only one to appear less than Akari.
- Attractive Bent-Gender: Whichever gender Konatsu deigns to dress up, he's absolutely gorgeous, to the point it's even a minor plot point in his only post-introduction focus story.
- Because You Were Nice to Me: He becomes slavishly devoted to Ukyo because she treats him better than the abusive family that raised him. Not very much better, admittedly, but still better.
- Bishōnen: Actually something of a spoof of the concept; he's a boy who looks so much like a girl that he thinks of himself as a girl.
- Butt-Monkey: The Universe seems to hate this boy. Forget Akane, forget Mousse's claims, or Ranma's vain melodrama. Only Ryoga has ever been as badly off as Konatsu, and only Ryu Kumon comes close.
- Camp Straight: He's a girly crossdresser and is in love with Ukyo.
- Cinderella Circumstances: Konatsu's mother died at a young age and his father, for reasons unknown, married a grotesquely hideous woman who already had two disgusting daughters, then died himself. Jealous of Konatsu's appearance, his stepmother and stepsisters treated him hideously and forced him to become their slave. Konatsu is pretty much Cinderella, except that here "she" turns out to be a man.
- Combat Pragmatist: He's a ninja and has very much assimilated this aspect of their fighting style.
- Crouching Moron, Hidden Badass: Yes, he's very goofy. But Happosai called him a "Genius Kunoichi" for a reason... even if he was wrong about the gender.
- Dogged Nice Guy: Loves Ukyo, but, unlike the rest of the cast, doesn't really act on it... at least not beyond trying hard to be of use to her, rescuing her if anything dangerous happens, and writing "I LOVE UKYO" all over his diary.
- Extreme Doormat: All capacity for active resistance has been beaten out of him (literally) over the years.
- Gender-Blender Name: Konatsu is a feminine Japanese name, which makes his gender reveal even more surprising.
- Last Minute Hookup: Subverted. Konatsu has all the right traits to fit this trope, being a Love Interest for Ukyo who is introduced in the last four volumes of the manga, and has only one story featuring him in a major role that isn't his introduction. The subversion is that Ukyo never shows any signs of reciprocating his feelings, and of course the manga concludes on its infamous No Ending, so nobody ever really hooks up conclusively.
- Leaning on the Fourth Wall: He can hide behind speech balloons.
- Long-Haired Pretty Boy: He has long hair that he wears tied back in a ponytail, which only contributes to his feminine looks.
- Masculine Girl, Feminine Boy: Feminine Boy to Ukyo's Masculine Girl.
- Me's a Crowd: Knows a legendary technique that allows him to do this.
- Mistaken for Gay: At first, Ranma and Akane assume that "she" is a lesbian when they discover Konatsu loves Ukyo, as they're convinced both that Konatsu is female and that "she" is aware of Ukyo's true gender.
- Ninja: A parodiac version, although in a different way to Sasuke.
- Perpetual Poverty: His stepfamily kept him in the most appalling conditions, never giving him the slightest amount of money. He, consequently, has almost no grasp of how money works; this is even central to his only post-intro focus story.
- Raised as the Opposite Gender: Biologically, Konatsu is male and he never denies it, but he's been brutalized and forced into the female role by his evil stepfamily for so long that he dresses, speaks and even instinctively reacts like a girl note . He also considers his love for Ukyo "forbidden" because of his instinctual identity.
- Skewed Priorities: A financial version. Due to being brought up under hideously Abusive Parents, Konatsu has absolutely no understanding of the real value of money whatsoever. Played simultaneously for laughs and drama (it's that sort of series) in his only post-intro focus story, where he almost bankrupts Ucchan's due to his incomprehension of how normal people define "average", "poor", and "extravant" by, amongst other things, selling his okonomiyaki for only 2 yen apiece because he thinks that's a fair price.
- Strong Family Resemblance: He looks very much like his deceased mother.
- Unsettling Gender Reveal: Does this to everyone in the cast at the end of his introductory story when his clothes get torn off and reveal the cute Konatsu as a guy.
- Wholesome Crossdresser: Dresses and acts like a girl because he was brought up to do so, but seems to avoid male garb only because he's too used to dressing as a girl and/or Ukyo likes his ability to attract hungry guys to her shop.
- Wooden Katanas Are Even Better: Zigzagged. Konatsu wields a wooden sword only because he's so poor that he pawned his steel blades to buy food. However, he's still devastating with his wooden swords because he's just that badass.
