The Main Characters
Voice Actors: Masami Kikuchi (Japanese), Matt K. Miller (English), Christopher Corey Smith (English; GXP only), Carlos Carvajal (Latin-American Spanish)
The main hero of the franchise, who is always presented as an ordinary high school student that ends up surrounded by women lusting after him as he struggles through various hijinks, and doesn't usually have much personality beyond that apart from being a nice guy.
- All-Loving Hero: Tenchi is the gentlest, most forgiving guy in his universe, ranging from tolerating the girls' hijinks most of the time to slapping and then embracing a Woobie, Destroyer of Worlds in the middle of a sobbing Villainous Breakdown.
- Amnesiac God: He has lost his memory of being a god.
- Armor-Piercing Slap: Only done twice between the second film (The Daughter of Darkness), and in the final episode of Tenchi in Tokyo.
- In the first instance, it was to break up the fight between Ryoko and Mayuka, in which Ryoko appeared to be the aggressor. Tenchi slaps her on impulse, to make her stop, but apologizes for it immediately afterward and tried to explain that he didn't know what to make of Mayuka. Though, later in the film, his grandfather reveals Ryoko had been acting on instinct to protect Tenchi, because she had sensed Mayuka was a threat to him.
- The one he gives Yugi was comeuppance for manipulating him and his family to split them apart, but was done mainly done to calm her down as she'd been in the midst of a Villainous Breakdown. After which, he tells her that he and the others didn't hate her and would've agreed to be friends with her had she simply asked.
- Author Avatar: Tenchi Masaki and Masaki Kajishima. It gets more obvious when you learn that the OVA is partly a showcase of Kajishima's personal harem fantasies. And the fact that the character essentially becomes stronger than the Chousin who created the universe is a strong hint too.
- Babies Ever After: While it's All There in the Manual, Tenchi will have several children with multiple members of his harem.
- Bad Liar: Sakuya calls him this in episode 10 of Tenchi in Tokyo, when he went on a date with Ryoko instead of her:Sakuya: I knew you'd be a terrible liar, Masaki.
- Beware the Nice Ones: He rarely gets angry, but when he does, he'll either give you a stern verbal smack down about your behavior, or her will fight you to the death
- Book Ends: The final scene of the third film in the Tenchi Universe continuity, mirrors the one from the first film's ending, by having him and Ryoko in the exact spot as his parents were and plays out in similar fashion: Ryoko finds him sketching on the hill, overlooking their home and, after brief bit of dialog, it ends with a still frame of them together (seen at 2:10-3:43). Which had affirmed them as the official pairing in the TV show.
- Brainwashed: Happens to him in an episode of Tenchi in Tokyo
- Chaste Hero: Unlike his sires, Tenchi has no perverted impulses and actively averts his eyes around naked women, even if they're trying to make him look.
- Clueless Chick Magnet: He honestly has no idea what these women see in him.
- Crouching Moron, Hidden Badass: He's an average student with average grades... then it turns out he's a part-alien prince with Laser Sword-wielding powers. In the Ryo-ohki OVAs, he also turns out to be a being stronger than the universe's gods!
- Deadpan Snarker: He has his moments, and when he does his wit has some of the sharpest barbs in the series.
- Facial Markings: In his Jurain armor.
- Flat Character: In most continuities, Tenchi just seems to exist as a plot device to keep the girls together and beat the enemy with awesome power. It's not really his fault as we rarely get to see things from his perspective because once the female characters show up their competition for him pretty much takes over the spotlight until it's time for him to come in and save the day. Other than those moments he is a Butt-Monkey who is Genre Savvy about being a Flat Character, "Tenchi Muyo!" roughly means "No Need For Tenchi!" much to his chagrin. This is a bit more mitigated in Tenchi in Tokyo where he has a bit more of a personality and tries to go out and live his own life without being defined by his Unwanted Harem, as well as Tenchi Universe.
- God in Human Form: In the OVAs, Tenchi turns out to be the human avatar of the god that created all of existence in the Tenchi Muyo franchise (yes, that includes Dual! Parallel Trouble Adventure and El-Hazard: The Magnificent World), and who is above even the Tenchiverse's three resident Choushin (lit. "super-deities"). He has no direct memory of this, but has recently been told about it.
- I Just Want to Be Normal: In Tenchi in Tokyo, where he moves away from his Unwanted Harem so he can have a peaceful life away from them. Naturally, this doesn't help, and not just because of them stalking him.
- Missing Mom: Kiyone (not to be confused with Kiyone Makibi) in the OVA continuity, Achika in the Universe and Tokyo continuities.
- Nice Guy: Most of the time, he's a very decent fellow.
- Nigh-Invulnerability: The power Light Hawk Wings give him. Things like Kagato's attacks, black holes, and pretty much anything less than complete destruction of the universe are nothing to him. but as he's a God in Human Form, he's actually not nighinvulnerable
- Not So Weak: Sure, he seems pretty harmless and innocent at first glance, he doesn't like fighting or hurting others, plus there's all the craziness he's subjected to by his harem. But do NOT mistake that for weakness, if Tenchi has to fight, or even kill, to protect those he cares about, HE WILL.
- The Omnipotent: In the Ryo-ohki OVA series, where it's revealed he's the entity that the Three Goddesses have been seeking — who is as far above them as they are above mortals.
- Story-Breaker Power: As demonstrated by Z, not only can Tenchi create the Light Hawk Wings, he can collapse all of reality solely by existing. Not to mention he's stronger than the three beings who created the Multiverse. So long, story conflict.... OVA only, however.
- Strong as They Need to Be: His power is confirmed by Z to work exactly like this. This applies to each Alternate Continuity as well in a meta sort of way for viewers who were around during Tenchi's run on Toonami.
- Super Weight: Level 6 normally. Level 7 as Kami Tenchi.
- Took a Level in Badass: In the second OVA and the Tokyo series Tenchi grows somewhat more assertive in his personality and isn't as afraid to give the girls hell (especially Ryoko) when he feels they've crossed a line.
- Tranquil Fury: Very notable in one story in the manga where, after Washu undoes the Laser-Guided Amnesia on the gang after Minagi is able to convince the others of Washu's existence and her need for help, the first thing he does is pull her into a hug, then tell her how disappointed he is in what she did.
Voice Actors: Ai Orikasa (Japanese), Petrea Burchard (English; Most of the series), Mona Marshall (English; OVA 3, GXP), Rosario Zamora (Latin-American Spanish)
An aggressive Space Pirate (who often doesn't do much of anything pirate related) and flirt that is usually the first girl Tenchi meets. Is by far the most flirtatious and hotheaded of the girls.Is the most popular girl amongst western audiences.
- Action Girl: Ryoko is one of the more adept at fighting among the main cast, being capable of flight, swordplay, energy attacks, and super strength. Some continuities vary her strength, but in all of them, she's superhuman at the least.
- Adaptational Wimp: Like many characters from the OVA, she gets a heavy downgrade in the powerscale in the Universe and Tokyo animes. Although, perhaps in a bit of a subversion, she's less often worfed in those continuities.
- Animal Motifs: Has a catlike tail and eyes, and a few feline traits, such as scratching at Tenchi's door when she wants his attention.
- Anti-Hero: Mellowing over time.
- Artificial Human: In the 11th episode of the OVA continuity, Washuu reveals that she created Ryoko by using her own egg cells and DNA from the Massusnote . Prior to that, Kagato said she was merely a "prototype" he had helped Washuu create. And Funaho eventually came to Earth so she could personally request that Washuu mass produce clones of Ryoko to strengthen Jurai's military. Washuu flatly answers, "no".
- Babies Ever After: Has a daughter in Masaki Kajishima's Tenchi Sokuhou manga who seems to have similar facial features as Tenchi◊.
- Blood Knight: Originally, and still loves to blow things up or get a good scrap. She tended to put in severe Power Limiters, so anybody whatsoever could pose any challenge.
- Book Ends: See the related entry in Tenchi's section.
- Brainwashed and Crazy: She gets corrupted Kagato.
- Butt-Monkey: She is usually on the receiving end of physical comedy.
- Cassandra Truth: In the second film, her statements about Mayuka being a threat is dismissed by Tenchi at first.
- Combo Platter Powers: She has so many powers that she periodically displays new ones without anyone commenting on it.
- Cry Cute: In the OVA, also sheds Manly Tears, Tender Tears, and Ocular Gushers. Come to think of it, she cries a lot, especially for an uber-badass Space Pirate Physical God(dess). Then again, considering the nature of her mother (see Washuu's Abusive Mom entry below), the fact that she was locked in a tomb for 700 years, and spent a good amount of time before that as a psychotic killing machine massacring millions if not billions for Kagato, her options were probably either tears or Stepford Smiler. Probably both.
- Damsel in Distress: In the first two OVAs, by Kagato and Dr. Clay, and in the SNES game.
- Subverted in the first episode of the Universe canon, where she just plays the part in order to get Tenchi and his folks on her side.
- Death Seeker: Implied as a part of her backstory in the OVA Continuity, as she was fully aware of Kagato's control over her, and was very self-destructive about it.
- Do Not Taunt Cthulhu: In the second episode, she laughs off Ayeka's initial attempts to torture her, then immediately regrets it as Ayeka simply changes methods, with more effective results.
- When Ayeka and Sasami's mother comes to visit, Ayeka explicitly warns Ryoko not to tease her for what she is about to do, which is calling her mother "Mommy". Ryoko doesn't listen, with predictable results.
- Double Entendre: In the second OVA episode:Ryoko: Now, I want your balls, please!Tenchi: Huh? (grabs his groin) No way! They're mine, and I'm gonna hang on to them!Ryoko: Oh, you numbskull, I meant the jewels on your sword!
- Double Standard: Rape, Female on Male: Exaggeration, but her constant clinging to Tenchi often borders on sexual harassment.
- In the Mihoshi Special (a Tall Tale story Mihoshi told based on one of her cases, with the Tenchi-crew filling the closest roles of the participants), "Ryoko" ties "Tenchi" to her bed, proceeds to undress him, and was about to rape him, but she was stopped by Pretty Sammy. This is somewhat averted though, although her sexual advances are Played for Laughs most of the other characters are not okay with them.
- Everyone Has Standards: In Tenchi in Tokyo she thinks that she may be a bitch, she may drink a bit too much and be quite selfish... but she will never betray anyone's trust and lie behind their backs.
- Exotic Eye Designs: She gets catlike eyes when she transforms into one.
- Facial Markings: While wearing her battlesuit.
- Femme Fatale: In the first few OVA episodes, before the audience learns where her affections lie.
- First Girl Wins: At least, in the original ending of the Universe continuity with the third film ("Tenchi Forever"), which resolved the Love Triangle between Ryoko and Ayeka, by having Ayeka concede that Tenchi had chosen Ryoko in his heart, and made peace with it (at 6:02-6:43).
- Good Bad Girl: Ryoko's flirtatious, but loyal to Tenchi.
- Hard-Drinking Party Girl: Expect to see her with a bottle of sake. Since she has the ability to instantly purge her body of any toxins, she never has to worry about a hangover...which is a good thing given that she probably drinks more alcohol in a night than a frat house does in a week.
- Frothy Mugs of Water: In the Toonami-edited version, Ryoko's sake becomes "tea," though no attempt is made to hide the fact that she's drunk.
- Intangible Man: She can phase through solid objects effortlessly. Combining this with her personality means she frequently invades Tenchi's privacy without warning.
- Iron Butt-Monkey: More justified in the OVA continuity, where she's capable of regenerating from anything. Interestingly, she tends more to be the one inflicting the pain in said continuity.
- Irony: In an official doujin by Masaki Kajishima, hers and Ayeka's daughters are best friends despite their mothers' intense rivalry.
- Jerkass: Generally, but Washuu, and mainly the merger with Zero, rehabilitated her remarkably quickly, so Jerk with a Heart of Gold when we last see her.
- Jerkass Has a Point/No Good Deed Goes Unpunished: In the second film, Ryoko's instincts alerted her to the fact that Mayuka was a threat to Tenchi's life, leading her to his bedroom just as Mayuka had been about to take him to Yazuha's realm in his sleep. Since the others didn't believe her when she tried to tell them, she took it upon herself to get rid of Mayuka by dropping her in the lake. Except she had a change of heart at the last moment and saved her, then opts to leave Mayuka stranded in a tree instead. When Mayuka finally makes it back to the house, she retaliates by slapping Ryoko, sparking a fight between them. Tenchi walks in moments later and assumes Ryoko started it, despite her attempts to warn him about her, and slaps Ryoko to get her to stop. At that point, she resigned herself to the fact that no would believe her and leaves.
- The Lad-ette: Ryoko's the most aggressive and boorish of the girls in all continuities.
- Lethal Chef: Her first attempt at cooking created some kind of acidic pink froth that dissolved the stove - out of what appeared to be the ingredients for vegetable soup. Later incidents tone it down, but her cooking (which involved incidents like frying fish by hurling energy bolts at them) still gets divided between the things that turn out wrong and the things that nobody gets to try. Supplementary materials say she has no sense of taste, which explains her cooking being bad, but is no excuse for it being actually destructive.
- Manic Pixie Dream Girl: She's about as manic and pixie as girls can get(perhaps moreso, as in many continuities she's engineered thus), and livens up Tenchi's life in a way he quickly becomes addicted to, but also demonstrates a Logical Weakness in MPDGs; Those lovable personality traits have led her to become a career criminal with absolutely zero impulse control.
- Meaningful Name: While "Ryoko" is a common Japanese feminine name, the kanji that are used to spell it in this case are very uncommon. This Ryoko's name translates to bringer of demons. Its meaning is even mentioned in the OVA (subtitled as "The Devil Caller.")
- New Powers as the Plot Demands: She can basically do anything within scale limits, including constructing extremely advanced inventions of her mother's design out of thin air.
- Ninja Pirate Zombie Robot: Lovesick, half-android, hyperintelligent, immortal demi-goddess, alien, drunkard layabout, bratty reformed space-pirate, child-soldier slave. To be honest, in-universe descriptions of her get very inclusive and vague. The Space and Time Adventures make this even worse by selectively including and excluding various traits and associated names to suit whichever 'reality' the characters are currently in.
- Physical Goddess: Not only her mother is one, but she has crazy amounts of power of her own.
- Pirate Girl: Allegedly.
- Considering her rap sheet in the OVA continuity...
- Psychopathic Womanchild: Originally, but she didn't have much of a choice, paid enormously for her crimes, and is much nicer nowadays, really. Just a trickster troll, but don't attack her, or threaten anybody she cares about. Worse, she was aware of what she was and tried a large number of self-destructive things before being defeated by Yosho.
- Reality Warper: In the OVA continuity, anyway.
- Sensual Spandex / Leotard of Power: Ryoko's black and red battle outfit.
- Shameless Fanservice Girl: She's happy to take Tenchi with her to the hot spring.
- Space Pirate: The one trait of hers that remains consistent through the continuities.
- Story-Breaker Power: In theory, she could generate up to ten lighthawk wings - That's twice as many as Z and as much as Tsunami's ship form if she could master her gems, making her incalculably powerful. Even without them, her Combo Platter Super Powers mean she'd be a force to be reckoned with, so she's usually not allowed to cut loose
- Suicide by Cop: One of the darker reasons for her limiting her powers in her backstory for the OVA continuity was because Kagato kept her under his control and she couldn't kill herself to break free.
- Superpowered Evil Side: In Tenchi in Tokyo.
- Super Weight: Level 4 with one gem. Level 6 at full power.
- Technopath: She can control Ryo-Ohki telekinectically, and she's been shown manipulating highly advanced machinery without using any technology.
- Teleporters and Transporters: Most incarnations of Ryoko can teleport to places she has previously been to.
- Tomboy and Girly Girl: The Tomboy to Ayeka's girly girl, Ryoko being the feisty fighter while Ayeka is a prim princess.
- Too Kinky to Torture: Averted. In the second episode, she explicitly tells a flustered Ayeka that she prefers sadism over masochism, yet right after she says this, Ayeka figures out a more effective method of torturing her, which results in Ryoko screaming in agony and begging her to stop.
- Vitriolic Best Buds: With Ayeka, in the Tenchi Universe continuity, where they segue from being bitter enemies, to simply taking digs at each other.
- Voluntary Shapeshifting: She became one with Zero, and could freely manipulate her body in extremely advanced fashions even before this, including duplication, phasing, regeneration, merging with inanimate matter, and so onwards.
- White Hair, Black Heart: She has white hair and a vicious personality.
- What You Are in the Dark: During the fight with Kagato, she could have easily defeated him , but it would have killed Ayeka in the process. Even though this would probably not have any future negative consequences for her, she refused to do so, even though she sorely wanted Kagato dead
- The Worf Effect: You can tell how powerful Kagato, Dr. Clay, and Z are because all three take her down easily (albeit in different ways). With the exception of Z, who really is just that powerful, the reason she lost is just below
- Worf Had the Flu: We've really never seen her at her full strength, let alone her full potential strength. She only ever had all 3 genuine gems in the flashbacks to where she was attacking Jurai, and even then she was under Kagato's control and trying to limit herself purposely. This goes a long way to explain why she rarely seems to be as effective as she should be
Ayeka Masaki Jurai
Voice Actors: Yumi Takada (Japanese; from 1st OVA to 3rd OVA), Haruhi Nanaonote (Japanese, from Ai Tenchi Muyo! onward) Jennifer Darling (English), Rebecca Forstadt (English; GXP only), Laura Orlazabal (Latin-American Spanish)
Princess of Jurai that has fierce rivalry with Ryoko over Tenchi, amongst other things.
- Action Girl: She's not as strong as Tenchi or Ryoko, but she's able to hold her own in a physical fight if she needs to throw down.
- Barrier Warrior: Ayeka's powers tend to focus on creating barriers to shield or entrap (and then zap) others. When serious, she skips the entrapment and zapping part to ram others with her force fields. It's strong enough to disintegrate robotic drones and hallways on the Souja.
- Berserk Button: She hates being called an "old maid", or "old bag", "old witch", etc. But more than that, Ryoko always brings out the worst in her.
- Bitch in Sheep's Clothing: In Tenchi Universe she can border on this. In the OVA she is simply a case of The Fettered. Almost maniacally attempting to manage a genetically very bad temper through excessive politeness.
- Brainwashed and Crazy: In the manga.
- Brother–Sister Incest: Ayeka was engaged to her half-brother Yosho so they wouldn't be rivals for the throne. While she was madly in love with him and was happy to be his bride, Yosho only saw Ayeka as his little sister. Incest apparently is not uncommon among the Juraian royalty, so this is never seen by any of the characters as a strange engagement.
- Covert Pervert: Rarely seen, but she has her moments:
Ayeka: (smiles suggestively) "Oohh myyy... so does that mean you-?"Ryoko: (smirks) "Hm...?"Ayeka: (regains composure) "N-nevermind that."
- Such as when she interrogated Ryoko, after capturing her, and noted the torture didn't seem to be working. Which made her wonder if Ryoko was a masochist. When she replies she's a sadist, Ayeka cups her face and blushes:
*Ryoko takes a closer look at what Ayeka's wearing*Ayeka: (nervously) "Wha-what is it? What do you want??"Ryoko: (smug) "Hmm... a new nightie... light makeup... (gasps, then grins) Why, I can smell your hormones!"Ryoko: (imitating Ayeka) "My mind and body are PURE!! MAKE LOVE TO ME!!" (smirks) "That's the message you're really trying to send."Ayeka: (red faced) "I-I-I AM NOT A WOMAN OF LOOSE MORALS!!"
- There was also the time Ryoko called her out on trying to seduce Tenchi, in episode 7:
- Damsel in Distress: Three times in the manga. Once by Yakage, another by Yataka and once again by Garyu. In the series proper, she was kidnapped by Kagato in Tenchi Universe.
- Demoted to Extra: By the time of the 3rd OVA, she appears less frequently.
- Everything's Better with Princesses: She has her moments, but isn't quite as sweet as Sasami.
- Facial Markings: In her Jurain battle armor.
- Graceful Ladies Like Purple: She has purple hair and is a proper princess. However, it's slightly cheating, since Word of God states that her hair is actually blue and she altered it to be purple in order to attract her half-brother/fiance Yosho.
- The High Queen: While Ayeka may have her vices and shortcomings, there's no denying her sense of nobility and strongly believes in fulfilling her royal obligations as crowned princess of Planet Jurai.
- I Want My Beloved to Be Happy: Near the end of the third and final film, Ayeka finally realizes Tenchi had chosen Ryoko in his heart, and makes peace with it. Then urges Ryoko to go to him while there was still time, before the parallel world collapsed. Just before the final scene, when she asks if anyone's seen Tenchi, Sasami replies he was at the top of the hill and that she'd seen Ryoko heading after him. Ayeka simply smiles.
- Jerk with a Heart of Gold: She's short-tempered and a prissy bitch, true, but if extremely caring and protective of those she loves (i.e. Tenchi and Sasami).
- Ki Attacks: She can shoot Ki blasts out of her hands, although she rarely uses them.
- Lady Drunk: Ayeka can really put away her sake, but rather than Ryoko who becomes a louder version of herself, Ayeka becomes more bitter and unladylike.
- Lady of War: She's able to fight with the best of them despite being a Proper Lady.
- The Nicknamer: She has several regarding Ryoko, with "monster-woman" and "demon" being the two she most often uses. But whenever Ryoko's being perverted, Ayeka calls her "dirt-for-brains".
- Noblewoman's Laugh: In the Japanese version. The English dub, especially of Tenchi Universe, does try to convey this.
- Not So Above It All: As much as she tries be and wants to believe she is... she really isn't. She can be just as juvenile as Ryoko, depending on the circumstances, or when she's riled up.
- The Ojou: She's girlish, of very royal blood and tries to be as ladylike as she can. Problem is, she has more pride and a hotter temper than she should...
- Onee-sama: To Sasami.
- Parental Neglect: Well, her father "had an empire to run", as they say in the UK, and as for her mother... well, calling her Cloud Cuckoo Lander is pretty generous, to say the truth. In the end she (and Sasami) was mainly raised by their grandmother.
- Princesses Prefer Pink: Her usual outfit is pink colored Japanese formal wear.
- Proper Lady: She tries her uttermost to maintain the decorum of a prim and proper princess, in order to set a proper example for her sister, Sasami. But Ryoko's teasing makes it difficult for her, to say the least.
- Rapunzel Hair: Like Ryoko's, her hair is long enough that extends halfway down her legs.
- Sparkling Stream of Tears: In the final episode of Tenchi Universe.
- Spell My Name with an "S": Either "Ayeka" or "Aeka" are acceptable, and the pronunciation is the same for both. note
- Spoiled Brat: Though not as much as some fanworks exaggerate her as.
- Super Weight: Level 3 on her own. Level 6 with Ryu-Oh.
- The Unfavorite: In the OVA continuity. It's not that bad, actually, but it's still Sasami who is Seto's darling.
- Verbal Tic: "-de arimasu".
- Vitriolic Best Buds: With Ryoko, in the Tenchi Universe continuity.
- Whip It Good: In her Image Song, "Call Me Princess!"
- The Woman Wearing the Queenly Mask: Especially in Tenchi Universe, where she shows genuine insecurities about her place and her duty within the Juraian royal family and considers herself as a mere puppet of them. Also see The Unfavorite.
- Yamato Nadeshiko: Attempts to play this role, but her own arrogance and jealousy undo her.
- You Gotta Have Blue Hair: She sports purple hair.
- In OVAs supplements it's mentioned that she originally had the same blue Kamiki hair as Misaki and Sasami, but altered her appearance to look more like Yosho's mother Funaho as an attempt to get closer to him. Apparently purple was as close as she could manage to Funaho's black hair. The process also made her hair straighter. This◊ is her natural appearance.
Sasami Masaki Jurai
Voice Actors: Chisa Yokoyama (Japanese), Sherry Lynn (English), Kari Wahlgren (English; GXP only), Alison Viktorin (English; Sasami: Magical Girl"s Club), Loreto Ayala (Latin-American Spanish)
Ayeka's younger sister, who despite being the youngest girl is generally the most mature. Is always close friends with Ryo-Ohki. Stared in her own series, Pretty Sammy and it's subsequent spin-offs.
- Apologetic Attacker: Right before her fight scene with Mashisu, Sasami gives this thoroughly characteristic line, "I'm not just gonna stand there and let you catch me. I'm really sorry." She then proceeds to wallop Mashisu.
- Badass Adorable: She's so huggable but don't forget she's Jurian royalty and has the power that comes with the title.
- Beware the Nice Ones: As a GP Agent finds out the hard way.
- Bratty Half-Pint: Mostly Flanderized away as time passes.
- Breakout Character: As the OVAs became a set of anime series, her importance grew and grew until she became the main focus in Tenchi in Tokyo alongside Tenchi himself. Let's not get started on the Pretty Sammy series where's she's the main character.
- Cheerful Child: Always upbeat.
- Cute Bruiser: in Tokyo where she pilots a Mini mecha.
- Dreaming of Things to Come: Her first dream prophesies Kagato's arrival and the second tells of Tokimi's involvement with Tenchi. However, Sasami can never remember the dreams fully - even though she called out Tokimi's name in the dream, she tells Tenchi that a woman was taking her away and that she never seen her before. As well, they also tend to be very disturbing.
- Bad Dreams: Because of Tsunami's influence on her.
- God Was My Copilot: She merged with Tsunami, of the three goddesses, in the OVAs.
- Morality Pet: For the Big Bad in Tenchi in Tokyo.
- No Periods, Period: Subtle mentions in OVAs 8 and 9.
- Only Sane Woman: Arguably the most emotionally stable girl in the main harem.
- Parental Neglect: Same with Ayeka, their parents were way too busy/crazy to pay them much attention, so Seto and Utsutsumi had to raise them.
- Precocious Crush: Sasami is implied (or outright stated) to have a crush on Tenchi in just about every continuity. She manages to fulfill this trope even in the OVA despite the fact that she's...
- Really 700 Years Old: Sasami is the official Trope Namer.
- Shy Blue-Haired Girl: Averted. She's outgoing and befriended Yugi
- Super Weight: Level 3 on her own. Level 7 as Tsunami.
- Team Chef: She does the Tenchi household's cooking.
- That Man Is Dead: Or in her case, "This Girl is Dead" She believes so in the OVA, since as a little girl she took a critical fall and Tsunami had to fuse with her. She believes that the real Sasami died then, and that she's just a copy created by Tsunami. In actuality she did survive, but barely. Doubles as Dark and Troubled Past because she was terrified Ayeka wouldn't love her anymore if she knew.
- Third-Person Person: In the Japanese version.
- Token Mini-Moe: The youngest and the cutest.
- Wise Beyond Their Years: The youngest and the most mature.
- You Gotta Have Blue Hair: She has a teal-blue shade of hair with it's brightness depending on the series (sometimes it looks like light blue-green and sometimes it looks a bit sky blue)
Voice Actors: Yuko Mizutani (Japanese), Michie Tomizawa (Japanese, OVA 4) Ellen Gerstell (English; OVAs 1-2, Mihoshi Special, Universe, Movie 1, Pretty Sammy Ep. 1), Rebecca Forstadt (English; Tokyo, Movies 2-3, Pretty Sammy Eps. 2-3, OVA 3, GXP), Colleen Clinkenbeard (English; Sasami: Magical Girls Club), Keyros Guillén (Latin-American Spanish)
An extremely clumsy and idiotic police officer that tends to end up chasing Ryoko. She is quite ditzy and has numerous running gags revolving around her airheaded nature and clumsiness.
- Adaptational Dumbass: See Flanderization below.
- Ambiguous Disorder: She takes ditziness and awkwardness to unprecedented new heights.
- Aren't You Going to Ravish Me?: Played as a running gag in the manga and PC-FX games, as Mihoshi's addiction to soap operas made her mistake some of Tenchi's actions as if he wanted to elope with her or just rape her. The catch? Mihoshi was more than happy with the idea, much for Tenchi's puzzlement.
- Boke and Tsukkomi Routine: Most definitely the boke to Kiyone's tsukkomi.
- Born Lucky: The laws of nature and causality bend around her to such an extreme that even Washuu can't predict her actions.
- The manga dedicates a full chapter to try to explain Mihoshi's weird ability to set any probability to her favor and benefit even from accidents and blunders. And showed how absurdly dangerous she'd be if she could actually control it.
- Cloud Cuckoolander: She seems like a complete airhead, but manages to save the day on several occasions. This is usually the result of her outrageous luck, but it's also indicated that she is much smarter than she seems... at least in the OVA continuity.
- Contralto of Danger: When she gets really serious, her voice sounds quite raspy and hulking.
- Cute Clumsy Girl: She's pretty and sweet, but she brings whole new meaning to the term "klutz"
- Dark-Skinned Blond: A trait shared by her entire extended family.
- Dumb Blonde: In most continuities. In the OVA she's more of a Genius Ditz.
- Fair Cop: An attractive space cop
- Flanderization: In the OVA she was a competent cop, but had been overworked to the point that she had a nervous breakdown and was forced to take a leave for her health. She'd just been reinstated when the series began, but she still wasn't back on the ball and made silly mistakes. The third OVA implies that something terrible and traumatic happened to her that caused her mental break, but nothing definite is ever pinned down. All other continuities portrayed her as a ditz from the get-go, with the understanding that she'd always been incompetent.
- The Fool: In most of the franchise timelines, whenever Mihoshi does anything useful, it's just through the sheer blind luck. She's a bit better in the OVAs, where she's more of a Genius Ditz rather than the complete idiot, and sometimes does (surprizingly complex) things on her own merit, but she's still a ditz even there.
- Friend to All Living Things: The genuinely kindest cast member.
- Genius Ditz: or The Ditz, depending on the series. Usually an expression of her Ambiguous Disorder, however; she's an excellent investigator... right up until she actually gets within six feet of who she's looking for. She writes extraordinarily precise reports that often contain useful information... if one can paw through hundreds of pages of it.
- Genki Girl: Always cheerful and full of energy, despite what damage she causes.
- Hard-Drinking Party Girl: In the OVA and manga, especially during the trip to Ryuten.
- Heavy Sleeper: Though she's also a sleepwalker. In fact, in the manga, she's the one who claims Tenchi's virginity; by sleepwalking into his bed on his wedding night and making love to him in her sleep — Ayeka and Ryoko are so busy squabbling that they don't notice until after she's finished.
- Imagine Spot: In the manga, they tend to involve some very lewd fantasies with Tenchi, which leave Mihoshi blushing and drooling, much to everyone's confusion.
- Innocent Fanservice Girl: Played straight on the PC-FX and Sega Saturn videogames, where Mihoshi's clothes tend to be much more revealing and she displays little or just no concern whenever Tenchi catches her half undressed. This is especially noticeable during the hot spring scenes, where Mihoshi doesn't even bother to cover herself with a towel whenever Tenchi enters into the bath, and is cranked up to eleven on the Sega Saturn game, where Mihoshi spends a considerable amount of time and cutscenes completely nude, without thinking twice about it.
- The Millstone: Especially in Tenchi Universe.
- Nice Girl: One of the sweetest of the group, surpassed only by Sasami
- Noodle Incident: The OVA universe has several mysterious references to an incident that destroyed Mihoshi's effectiveness as a detective, leading to her being reassigned to patrol near the Earth by the time she first appears.
- Reality Warper: With absolutely no control over, or even knowledge of, her powers — a trait apparently inherited from her mother in the OVA universe.
- Romantic Two-Girl Friendship: Mihoshi seems strangely attached to Kiyone, and even Kiyone has her moments, especially in episode 6 of the Universe series.
- Satellite Character: In the Universe and Tokyo continuities, Mihoshi's whole purpose seems to revolve around hanging off Kiyone. Kiyone herself may fit to a lesser degree.
- Saying Too Much: One of Mihoshi's running gags in Universe is thoughtlessly blurting out information that embarrasses another character — usually revealing a particularly pathetic aspect of the Perpetual Poverty she and Kiyone live in.
- Super Weight: Level 3 physically, but who knows her real level? Her causality-bending abilities are so powerful that even Washuu cannot circumvent them, but they're completely uncontrolled.
- Tangled Family Tree: Is Washuu's great-great-granddaughter, and Ryoko's great-grandniece. She's also related to about half of the important people at the Galaxy Police thanks to being a daughter of the powerful Kuramitsu family.
- Took a Level in Dumbass: In the OVA 1 she went from a ditzy but focused officer to a lazy fool that couldn't remember her own brother's name by the end of OVA 3.
- It was less that she couldn't remember his name and more that apparently her image of him is stuck on his teenaged self. He had to show a picture of him when he was younger for her to recognize him, but she recognizes other people from his crew with whom she has only occasionally interacted quite easily. Her backstory suggests her overall goofiness came about when a past Did You Just Romance Cthulhu? relationship went Horribly Wrong and she only survived with this much of her mind intact because she's Washu's descendant and has the luck to make a leprechaun jealous.
- In some of the alternative universe stories, she's literally so stupid she has trouble telling the difference between left and right, up and down, etc.
- Verbal Tic: "-desu".
Voice Actors: Yuko Kobayashi (Japanese), Kate T. Vogt (English), Jessica Gee (English; GXP only), Luci Christian (English; Sasami: Magical Girls Club), Carol Knuckey (Latin-American Spanish)
A cheerfully neurotic mad scientist who won't do anything unless it amuses her. Fortunately for her housemates, heroism and support thereof are two things that amuse her. Unfortunately for the same, so are public humiliation, Baleful Polymorphs and S&M. Her inventions treat the laws of physics more like guidelines, and often jumpstarts plots - either due to Deus ex Machina or simply because she's every bit as childish and irresponsible as her daughter Ryoko, whom she fights with almost as often as Ryoko fights with Ayeka.
- Abusive Parent: In the OVA (where she created Ryoko), she once straps Ryoko into an apparently escape-proof lab-table, turns off the lights and then runs off and hides. Ryoko is so afraid of being trapped alone in the dark that she starts crying and pleading for Washu to come back and rescue her. Washu is not only well aware of how badly this scares Ryoko, but is actually just around the corner, gleefully taping Ryoko's cries for "mommy."
- Animal Motifs: Washu's signature is a happy crab. It makes sense when she wears head coverings, and her bangs take the shape of crab legs. Apparently this was meant as a connection to Kagato, whose symbol was the serpent, thus linking the two to an old Aesop's fable about a crab and a snake once being friends but eventually turning on each other when the snake refused to stop being evil.
- Brick Joke: When dealing with Dr. Clay and Zero.Zero (disguised as Ryoko): If I take you to Dr. Clay, then I won't have to kill Tenchi!Washuu (having replaced herself with a doll of herself): What are you doing with that? I didn't know Dr. Clay went for that sort of thing! If it's a present, I can put a ribbon on it!'''
Washuu: I even remembered the ribbon!Dr. Clay: *growls*Washuu: If you give back Ryoko and leave Tenchi alone, I'll give it to you as a gift! But don't do anything indecent with it, ok?
- Later, when evading Dr. Clay's Combat Tentacles trap in exactly the same way...
- Broken Bird: In the OVA continuity; she's still strongly scarred from when the man she loved was forcibly forbidden from being with her due to different social standings (he was higher classed than she), which was made worse than they kidnapped the son (who turns out to be Mihoshi's great-grandfather) they had and refused her access to him for the rest of her life.
- Compressed Hair: How does she get all that pink hair under that little green cap in episode 12, anyway?
- Crystal Prison: In the OVA, she was trapped in a huge gem placed inside a closed Pocket Dimension within Kagato's ship. When Mihoshi stumbles into said dimension and starts fighting a monster inside it, the energy released starts cracking the gem's surface; once the monster somehow becomes Taken for Granite (and just few inches away from poor Mihoshi), Washu is able to break free safely, crushes the petrified monster and introduces herself to Mihoshi.
- Cute Bruiser: Even in her child form, she's capable of lifting a heavy chair and punching through solid concrete. In the manga, she even suplexes her Evil Counterpart. Would count as a Genius Bruiser if she was more muscular. But then again, Muscles Are Meaningless when you've got the power to shape the universe.
- Demoted to Extra: Had a diminished role in both the Tenchi Universe and Tenchi in Tokyo series, to the point where she barely had an impact in the second half of both shows until their respective finales.
- Double Standard: Rape, Female on Male: See Naughty Nurse Outfit.
- Dual Age Modes: At least in the OVA, she switches between child and adult forms.
- For Science!: Washu does a lot of less-than-wise things in the pursuit of scientific advancement. Universe Washu may be the most infamous, where she invents (and is implied to have tested) dimension-oscillating bullets, an ozone destroyer cannon and a space/time converting tachyon ray — and is then baffled where the fact she did this is considered grounds to imprison her in a stasis capsule and exile her to a backwater part of the universe (and after being pardoned, she goes on to invent a cannon capable of destroying galaxies) — but even OVA Washu has done this from time to time.
- Genius Ditz: A nice way of looking at Universe Washu; she's a scientific genius, but not very sensible. In her first episode she genetically transmutes Ayeka and Ryoko into kappas for perceived mockery. Her Mad Scientist antics seem to be done purely for a combination of the love of inventing without thinking of the consequences (even if she did blast three worlds with Wave Motion Cannons, her cause was purely to test that they worked — she never stopped to think about the consequences except in the "break a few eggs" sense). She even has two drones in the form of Super-Deformed dolls of her that exist solely to stroke her enormous ego.
- God Was My Copilot: In the OVA, it turns out she's one of the three goddesses who created the universe.
- Immortal Immaturity: For all of her criticism of Ryoko, it's clear on occasion that Washu's just as lacking in the maturity department if not moreso—and not just because of her youthful disguise.
- Insistent Terminology/They Call Me Mister Tibbs: "No! I'm not gonna help you unless you call me Little Washu!" (Washu-Chan in the Japanese version).
- Jerk with a Heart of Gold: Occasionally bordering on Jerk Ass, but she is mostly a nice and caring, if very quirky, person.
- Mad Scientist: Especially in Tenchi Universe, where it's taken to new levels.
- Moment Killer: In the final episode of Tenchi in Tokyo. Ryoko strangles her for ruining her moment.
- Naughty Nurse Outfit: In OVA 7 for her... experiments on Tenchi. And then Mihoshi walks in the lab...
- Omnidisciplinary Scientist: By her own words, she's created things from Ryoko to Souja, so she has a grasp of everything from genetics to engineering. She's also good at medicine if the infamous Nurse Washu scene is any indication.
- When asked why she's unable to escape from Souja, given that she created and thus should know all its weaknesses, Washu points out that her creating it is why Souja doesn't have any weaknesses to exploit.
- The Omnipotent: In the OVA, she's one of the three gods who created the omniverse and all higher dimensions as an experiment to find a being greater than themselves.
- Really 700 Years Old: Looks like a child/young teenager, but is in fact older than all of 22-dimensional reality.
- She Is All Grown Up: Looks like a teen girl, but has an adult form that is breathtakingly beautiful. And her Goddess state, which is essentially her adult form with a Pimped-Out Dress, fits what you'd expect from a Physical God(dess). This only applies in the OVA, whereas the child-like form seems to be her natural form in Tenchi Universe and Tenchi in Tokyo.
- Super Intelligence: She is , by far, the most intelligent character in the series.
- Super Weight: Level 3 or 4 in mortal mode. Level 7 in Megami form.
- Truly Single Parent: Of Ryoko in the OVA, whom she created using one of her eggs and the Mass, a sentient alien species.
Voice Actors: Etsuko Kozakura (Japanese), Debi Derryberry (English), Mona Marshall (English; GXP only), Zach Bolton (English; Sasami: Magical Girls Club), Viviana Navarro (Latin-American Spanish)
A rabbit like alien with a cat's head and ears as long as her body that makes cat noises. As such fans refer to her as a cabbit. She is close friends with Sasami and eats nothing but carrots, and transforms into a space ship.
- Animal of Mass Destruction: Her ship form is often depicted as this.
- Big Eater: Tenchi often has fields of carrots just so Ryo-Ohki can eat them.
- Bizarre Alien Biology: OVA Ryo-Ohki is technically Ryoko's half-sister, as both of them are based upon the genetic information of the alien lifeforms known as Mass. Ryoko simply hybridizes Mass genes with Washu's genes.
- Cute Kitten Bunny: She combines the cuteness of kittens with the cuteness of bunnies, for a massive cuteness overload.
- Cute Monster Girl: In the OVA continuity, she learns to shapechanges into a more anthropomorphic form. In fact, she develops two forms; one fully mature, and one child-like, tending to use the latter so she can properly adjust to things like walking on two legs. In the adult form, she basically looks like a cabbitgirl version of Ryoko.
- Dating Catwoman: In Tenchi Universe she falls in love with Ken-Ohki, who belongs to Ryoko's rival Nagi.
- Extreme Omnivore: In the OVA, she infamously ate Mihoshi's gun once.
- Head Pet: Ryo-Ohki likes to ride around on peoples' heads and shoulders, particularly Sasami's in the OVAs.
- Interspecies Romance: In the manga, she eventually masters her humanoid form and marries Tenchi as well, giving birth to his triplet daughters.
- Living Ship: She's a spaceship, but she's also alive and fully sentient and sapient
- Mix-and-Match Critters: Which is what Ryo-Ohki (as well as Fuku and Ken-Ohki) are. Specifically, rabbits and cats (dubbed "cabbits").
- Only One Name: She is only referred to by her actual name.
- Precocious Crush: Yep, she loves Tenchi, too. So much that, in the manga, she went to great lengths to learn how to walk in her adult form, just to go on a date with him. The OVAs portray this as more of a Precocious Crush seeing as her standard form is a small child with cabbit ears.
- Ridiculously Cute Critter: A fluffy little cabbit — a cat/rabbit hybrid. She also turns into a starship - a Cool one, not a cute one, though. In Tenchi in Tokyo, she also has a Mini-Mecha form. This one is cute.
- Series Mascot: Appears on almost all Tenchi-related merchandise. She's also the reason carrots are such a recurring motif throughout the various series.
- Shapeshifter Baggage: Can transform from a cat-sized creature to a house-sized spaceship. She can also transform into several hundred cat-sized creatures, and many other things in between.
- Super Weight: Level 3 in humanoid form according to the Seikishi Monogatari Doujinshi. Level 6 as a spaceship.
- Trademark Favorite Food: Carrots. She's so obsessed with them that she causes Sasami's ship to crash in Tenchi Universe by charging full-speed into it, while in ship form, after seeing on a video-link that Sasami has a carrot. Heck, she and Tenchi bonded over carrots in the OVA, since he's the one always planting and harvesting them.
- Transforming Mecha: In Tenchi in Tokyo, Ryo-Ohki can transform into a pink Cabbit mecha, who can move autonomously, or is piloted by Sasami.
- Truly Single Parent: Ryo-Ohki can produce eggs containing physical/mental clones of herself as a way to survive if she takes too much damage. She does this in both the OVA and Tenchi Universe, and in both continuities Ryoko uses her egg to play a joke by claiming Ryo-Ohki is actually her and Tenchi's love-child.
Katsuhito Masaki/Yosho Masaki Jurai
Voice Actors: Takeshi Aono (Japanese; Katsuhito), Takehito Koyasu (Japanese; Yosho), Kunihiko Yasui (Japanese; Binpachi), Masamichi Ota (Japanese, child), Jay Hopper (English; 1st Katsuhito), Matt K. Miller (English; 1st Yosho/Binpachi), Richard Cansino (English; 2nd Yosho), Bob Papenbrook (English; 2nd Katsuhito/3rd Yosho), Barbara Goodson (English, child), Marco Antonio Espina (Latin-American Spanish)
Tenchi's grandfather. A shinto priest and a skilled warrior, he is training Tenchi to follow in his footsteps. He is also the crown prince of planet Jurai.
- Badass Grandpa: Literally, how much depending on the continuity, anyway. OVA-wise, he took on and defeated a 3-Gem Ryoko in single combat and sealed her. The same Ryoko who had previously curb-stomped the entire Jurian Military, minus a few key players.
- Cool Old Guy: He's a rather swell man and has quite the patience.
- Covert Pervert: He once copped a feel of Ryoko and quite enjoyed it.
- He also proposed that he and Ayeka get married anyway despite being an old man at the time not really.
- In the second movie, he also tells Mayuka that "Next time, you can take a bath with your grandpa!"
- Foreshadowing: One of the early signs that he's more than he appears occurs when he effortlessly blocks a punch from Ryoko, who's visibly puzzled by this. In the background of the following scene she demolishes the stairs with the same punch, seemingly to make sure it still works.
- Momma's Boy: Unusually strongly attached to Funaho, which even gets lampshaded in-universe. It's the reason why Ayeka tried to change her hair from her mother Misaki's bright blue to a black to match Funaho's. The dye didn't take and the closest she could get was her iconic purple.
- Obfuscating Stupidity: Loves acting like an old geezer but is capable of training his grandsons (Tenchi and Kenshi) to master-level martial artists.
- Outliving One's Offspring: He outlives his beloved daughter Achika, the mother of his grandson Tenchi.
- Retired Badass: Not entirely by his own decision, though. Funaho (his tree, not his mother, mind you) apparently took root, and thus he cannot leave Earth anymore, because Juraian royalty can remain immortal only in the range of their trees. Even then, if not for Washuu's gems implanted in the Master Key, he would have died hundreds of years ago. In the Universe version, it's because of the guilt of killing his best friend, Kagato.
- Super Weight: Level 4 on his own. Level 6 in his now stranded royal tree ship.
- Team Dad: When it comes down to it, the other cast members look to him for (grand)fatherly guidance
- Younger Than They Look: In the OVA, he's actually very young looking, but maintains an older guise in order to blend in better Averted in Tenchi Universe where he actually looks his age
Voice Actors: Takeshi Aono (Japanese), Toshiyuki Morikawa (Japanese, young), Jay Hopper (English; OVAs 1-2, Universe, Movie 1), Bob Papenbrook (English; Tokyo, Movies 2-3, OVA 3), Andrew Philpot (English, young), Javier Rodríguez (Latin-American Spanish)
Tenchi's father, a rather well-regarded architect and one of the few relatively normal humans in the cast (except in the OVA). He serves as the perverted Id of the series, generally getting a kick out of the bevy of pretty young ladies who've come to stay in his home.
- Bumbling Dad: He's pretty much an idiot. This is taken up to 11 in Tenchi in Tokyo, where its a wonder how he's still alive.
- Dirty Old Man: He likes to do perverted things to women. Less so in some versions.
- Happily Married: To Rhea in the 4th OVA.
- I Was Quite a Looker: Was a cute Megane when young.
- Older Than They Look: OVA continuity-only), where he's pushing 300.
- Strong Family Resemblance: Subverted. He marries into the Masaki family (Katsuhito's children Achika/Kiyone and Minaho were both female) and took the surname so it wouldn't be extinguished, but he looks remarkably like his father-in-law. Katsuhito lampshades it in Tenchi Universe by saying no one would've guessed that Nobuyuki isn't related to him.
- Justified in the OVA continuity where, though he married into the Masaki family, he was the descendant of the wife Katsuhito married and then buried before marrying Airi. In other words, he is also a grandson/great-grandson of Katsuhito.
- Super Weight: Probably level 2 given that he is over 200 years old.
- Team Mom: Mostly in Tenchi Universe and Tenchi in Tokyo.
- Would Hit a Girl: In one of the manga volumes, Noboyuki slaps Ryoko after she picks on Mihoshi one too many times. He then explains that Mihoshi donates her pay from her Earth jobs to cover the damages she causes with her less than perfect landings.
Azaka and Kamidake
Voice Actors: Kenichi Ogata (Japanese; Azaka), Wataru Takagi (Japanese; Kamidake), Phil Fox (English; 1st Kamidake), Jack Fletcher (English; 2nd Kamidake), Doug Stone (English; 4th Kamidake), Mark Tracy (English; 1st Azaka, 3rd Kamidake), Michael Sorich (English; 2nd Azaka), Mauricio Aravena (Latin-American Spanish; Azaka) and Pablo Krogh (Latin-American Spanish; Kamidake)
Ayeka's bodyguards, two robots who resemble tree trunks. Only distinguishable by the colored kanji on their "faces." In the Universe continuity, they house the souls of two legendary Juraian knights, and adopt human forms towards the series end.
- Adaptational Badass: One of the few characters that actually got stronger in the Universe canon, they get much more powerful knight forms, who are among the most powerful of the cast. In the OVA, they are more or less jokes.
- I Don't Know Mortal Kombat: In Tenchi Universe, Knight!Azaka gets beaten by Sasami a lot.
- Only One Name: They are referred to only by their first name.
- Robot Buddy: Wooden robot, but still.
- Sealed Good in a Can: In the "Universe" continuity.
- What Happened to the Mouse?: Their Knight forms aren't seen or even mentioned in Tenchi Muyo! In Love, despite it taking place after the end of Universe. They do make small cameos in the film's sequel.
- The Worf Effect: While they are Ayeka's designated bodyguards, they only seem to appear in the story to be quickly defeated by the new bad guy.
Tsunami (OVA and Manga)
Voice Actors: Chisa Yokoyama (Japanese), Sherry Lynn (English), Lara Cody (English; Pretty Sammy Eps. 2-3 only), Maureen Hermann (Latin-American Spanish)
The patron goddess of Jurai, and the "mother" of the royal trees. Washu and Tokimi are her sisters.
- The Omnipotent: "Mother" of the royal trees, which give most of the characters their power.
- Only One Name: Only known by her surname.
- She's All Grown Up: Sort of. Sasami will grow up to
look likebe her.
- Super Weight: Level 7. Her ship form is a 6
- You Gotta Have Blue Hair: She has light blue hair, in this case.
Voice Actors: Yumi Touma (Japanese), Jennifer Darling (English; OVA 2), Mari Devon (English; OVA 3)
A goddess who is the sister of Tsunami and Washu. Called the best fighter of the Choushin by her sisters themselves.
- Blue and Orange Morality: As a Chousin, she knows nothing about what is good and what is evil.
- A God Am I: When asked why she appeared above the altar for a family marriage ceremony, she responds nonchalantly "What more fitting place for a Goddess?"
- Jerkass Gods: Heavily implied to be one of these by the end of OVA 2. By the end of OVA 3, not so much. She honestly didn't expect that ruining a guy's life and giving him phenomenal cosmic power could backfire horribly. She wasn't evil, just terribly naive.
- The Omnipotent: Subverted in OVA 3.
- Only One Name: Only known as Tokimi.
- Super-Deformed: Her appearance after she moves in with Tenchi.
- Super Weight: Level 7
Kiyone Makibi (Tenchi Universe and Tenchi in Tokyo)
Voice Actors: Yuri Amano (Japanese), Sherry Lynn (English; Mihoshi Special, Movie 1, Pretty Sammy Ep. 1, Universe), Wendee Lee (English; Tokyo, Movies 2-3, Pretty Sammy Eps. 2-3), Sara Pantoja (Latin-American Spanish)
A space cop that has the misfortune of being partners with Mihoshi, whose clumsiness continuously ruins any chances of of a promotion. While she doesn't appear in the canon OVA storylines, she is a major presence in the Universe and Tokyo timelines, becoming a full-fledged member of the harem alongside the main five girls.
- The Ace: Of the Galaxy Police, and of any other job she takes on. In Universe, she was even shown as being exceptionally good as a Burger Fool.
- Boke and Tsukkomi Routine: Definitely the tsukkomi to Mihoshi's boke.
- Canon Foreigner: She's never been a part of the canon OVA, although she's in pretty much everything else.
- The Chew Toy: Suffers repeated misfortunes from Mihoshi that sometimes have her as a borderline Woobie.
- Curtains Match the Window: Her eyes are a similar color to her hair
- Fair Cop: She's very attractive for a cop, and unlike Mihoshi, she's actually consistently competent.
- Flanderization: She went from being a likable and generally sympathetic character in her early appearances in Tenchi Universe, to a Jerkass whose only concern was getting promoted in Tenchi In Tokyo, at least until about episode 20.
- Harem Nanny: Generally tries to keep Mihoshi's bumbling in line, and has demonstrated that she could restrain Ryoko during her more violent outbursts. She's also more dependable than the other residents in matters of finances, which becomes a factor when the group runs out of food.
- The Not-Love Interest: Notable in that she's one of the few female characters who is exceptionally close with Tenchi without ever becoming infatuated with him, which gives the two of them a special relationship sometimes bordering on Platonic Life-Partners, at least in Universe. Kiyone falls for him in Tokyo, though, stating that he'd be better off with a law-abiding citizen such as herself. At any rate, in either continuity, her job comes first.
- Only Sane Woman: In Tenchi Universe she is by far the most down-to-earth and reasonable of the women living in the Masaki house.
- Super Weight: Level 2
- You Gotta Have Blue Hair: She has teal hair.
Nagi (Tenchi Universe)
Voice Actors: Mizuki Ohtsuka (Japanese), Julia DeMita (English)
A bounty hunter obsessed with capturing Ryoko.
- Amazonian Beauty: Only seen during the swimsuit competition. Nagi removes her cape, followed by a montage of close-ups of her abs, thighs, and calf muscles, ending with a full-body shot of her figure. The crowd went. Went. WILD! Guess who won?
- Arch-Enemy: To Ryoko.
- Badass Normal: She has no superhuman powers like Ryoko, but she can still best her in a fight.
- Beautiful All Along: She's a very tough and badass bounty hunter but that doesn't mean she's not still a beautiful woman. In the Beach Episode, she easily beat Ryoko and everyone else in a swimsuit contest. Of course Ryoko stole the prize money and fled the planet with others in tow anyway.
- Berserk Button: Do not cheat or swindle her, seriously, just don't. Ayeka learned this the hard way.
- Bounty Hunter: Her chosen profession. and she's real good at it too.
- Dark Action Girl: given her rivalry with Ryoko.
- The Dreaded: She's got quite the reputation, and well deserves it. Her mere implied presence is enough to make Ryoko shed ger typical attitude and become completely serious.
- Hello, Nurse!: Seen when she enters a swimsuit contest to compete with Ryoko. Not only did the judges allow for her last minute entry, the crowd went wild when they saw her figure. She won by a landslide vote.
- The Only One Allowed to Defeat You: Nagi's beef with Ryoko borders on obsession and predates the start of the series by an unspecified (albeit, presumably long) amount of time.
- She won't allow anyone else to capture, or kill Ryoko; not even the Galaxy Police. So she helped Ryoko escape, just so she could capture her later.
- When Nagi found out Ryoko was competing in a swimsuit contest, she initially blew it off and said she'd wait 'til it was over. But the thought of anyone else beating her was too much, causing Nagi to change her mind and join the competition as a last minute entry.
- Only One Name: If she has a last name, its unknown
- The Rival: To Ryoko
- Royal Rapier: A high-tech version of one serves as her Weapon of Choice. Its tip can even fire Frickin' Laser Beams!
- Super Weight: Level 3 with equipment.
- Weak, but Skilled: Ryoko's significantly less powerful in the Universe continuity, but still very much superhuman. Nagi isn't. She dominates Ryoko in their fights anyway.
- Whip It Good: Her other Weapon of Choice: an energy whip that can tear the hell out of anything it makes contact with.
- You Gotta Have Blue Hair: She has grey hair.
Mitsuki (Tenchi Universe)
Voice Actors: Yuka Koyama (Japanese), Debi Derryberry (English), Isabel Quinteros (Latin-American Spanish)
Kiyone's rival at the Galaxy Police.
- Evil Redhead: Maybe evil is too much, but she's an ass.
- Fair Cop: Despite being a complete bitch, she's fairly attractive.
- Jerkass Redhead: She seemed to enjoy arresting Kiyone a bit too much.
- Laser-Guided Karma: Reassigned to be Kiyone and Mihoshi's assistant at the end of the series.
- Only One Name: Or at least, thats all we know.
- The Rival: She seems to have a grudge with Kiyone, though it's never explained why. So any time she's assigned to a major case, or if she gets a promotion, she's quick to flaunt it.
Achika Masaki (Tenchi Muyo! in Love and Tenchi Universe)
Voice Actors: Megumi Hayashibara (Japanese), Grace Zandarski (English)
A girl from 1973 who Tenchi meets during the events of the first movie, who is later met again as a ghost in the modern day during the events of Tenchi Universe. She is actually Tenchi's late mother.
- Action Mom: Tenchi and the girls go back in time to save her from Kain in Tenchi in Love, and end up stopping him thanks to her.
- Beware the Nice Ones: Go ahead, ask Kain why it's a bad idea to piss her off. Oh, right...
- Cast from Lifespan: According to Tenchi's narration at the end of the first film ("Tenchi in Love"), the Jurai power that would have prolonged Achika's life was passed onto him at birth. Which significantly reduced her life span to only a few years afterward.
- Does This Remind You of Anything?: Her final attack is near identical to Squall Lionheart's "Blasting Zone", frame-for-frame (seen at 0:54-1:14).
- Facial Markings: When her Juraian power awakes, a striped triangular shaped marking appears on each of her cheeks.
- Lady of War: Once her powers awaken, she's overcome with Tranquil Fury as an elegant lavender kimono materializes around her body and Sword "Tenchi" transforms into a laser bladed naginata! Kain never stood a chance.
- The Lost Lenore: To Nobuyuki, who hasn't remarried since her death.
- Luminescent Blush: Seen during tender moments between her and Nobuyuki, when they were in highschool. Particularly when she first notices him filming her during their class trip, and while they were alone on the hill overlooking the site where Nobuyuki would eventually build their dreamhouse.
- Mama Bear: She is fiercely protective of Tenchi. even before she gives birth to him
- Nice Girl: In her lifetime, she was warm, compassionate, and well liked by her family and friends.
- Ordinary Highschool Student: At least, she was, until her Jurai powers were awakened.
- Posthumous Character: The film takes place in the past, in the year 1973, which was roughly 17 years before Tenchi was born. She's long deceased in the present, having died several years after giving birth to him.
- Rescue Reversal: Tenchi and the others travelled back in time in order to protect her from Kain. Except she ends up saving them by killing Kain, herself.
- Super Weight: Level 5 versus Kain.
- This Is Unforgivable!: Had Kain left Nobuyuki alone, Achika would've resigned herself to her fate and accepted defeat. But seeing Kain torture the love of her life, right in front of her, was the impetus that made her draw out her full power and smite the hell out of him.
- Tranquil Fury: Instead of Berserker Tears, she goes stonefaced and severs Kain's arm. As he's howling in pain, she firmly tells him why he was about to die. Then unleashes her full fury by splitting him down the middle with a single sword stroke.
Kazuhiko Amagasaki (OVA and Tenchi in Tokyo)
Voice Actors: Toshiharu Sakurai (Japanese), Mark Tracy (English; OVA 1), Michael Sorich (English; OVA 1 Toonami Edit, Tokyo), Pablo Ausensi (Latin-American Spanish)
A perverted classmate of Tenchis'. Gets an expanded role in the series Tenchi in Tokyo.
- All Men Are Perverts: Or at least dirty minded, as upon Tenchi mentioning he fought a mummy (long story), his first thought is as to whether or not the mummy was good looking, and if so, if Tenchi managed to "score". Tenchi clobbers him.
- Ascended Extra: He is a recurring character in Tenchi in Tokyo.
- Gonk: There used to be a Gonk sub-trope named after his physical appearance; The Fat Guy With Big Lips And A Pimply Nose.
Sakuya Kumashiro (Tenchi in Tokyo)
Voice Actors: Mayumi Iizuka (Japanese), Julie Maddalena (English), Viviana Navarro (Latin-American Spanish)
A all round normal girl Tenchi's age that has no crazy personality traits that befriends Tenchi after he moves to Tokyo, so naturally he ends falling for her and she serves as his love interest for the series. Late in the series it's revealed that she was created by Yugi as an ideal girlfriend for Tenchi to drive a wedge between him and the other characters so they will leave and take the crystals that can stop her that they have with them. She has no idea of this, however.
- The Ace: At school she's athletic, popular, rather booksmart, etc. The fact that she's a sort-of "shadow" created by Yugi might have had something to do with it.
- Clingy Jealous Girl: Develops some traits of this, though this is somewhat understandable since she was created solely to love Tenchi and has just begun to realize that there's something wrong with her lack of identity outside of Tenchi.
- Damsel in Distress: Not necessarily her fault, since she's the only one in the Unwanted Harem without powers, weapons, or superpowered mascots.
- Dying Moment of Awesome: She could have sorta lived on in the Lotus-Eater Machine, but she decided otherwise. See Heroic Sacrifice.
- Heroic B.S.O.D.: Sakuya has one when she realizes that she has no memories of any family of her own. When this happens she's seen in a Troubled Fetal Position on the floor, sobbing and murmuring Tenchi's name.
- Heroic Sacrifice: When Yugi locks Tenchi in a Lotus-Eater Machine with Sakuya as a bait, she ultimately chooses to sacrifice the last bits of her existence and willpower to give Tenchi a Rousing Speech and send him back to reality so he can reunite with the girls and defeat Yugi. Easily her Crowning Moment of Awesome.
- Ordinary High-School Student: she at least appears to be at first.
- Proper Tights with a Skirt: Her winter uniform.
- Raven Hair, Ivory Skin: She has pale skin, dark hair and is rated 3 on her school "Must Have List" by all the guys, who get jelous of Tenchi when she starts taking a liking to him.
- Really Dead Montage: The special end credits for episode 24, with her image song, "Kataomoi (Unrequited Love)" performed by her voice actress, Mayumi Iizuka.
- Third-Option Love Interest: And watch Ryoko and Ayeka froth at their mouths!
- Tomato in the Mirror: She is Yugi's shadow, an extension of her body and soul. She didn't know it until Yugi came to reclaim her. And even if you hated her, it's not hard to feel sorry for her.
Mayuka (Daughter of Darkness)
Voice Actors: Junko Iwao (Japanese), Julie Maddalena (English)
A young woman who appears during the events of the second film, Daughter of Darkness, claiming to be Tenchi's daughter from the future.
- Big Brother Attraction: Towards Tenchi, who despite being her "father", acts much more like a protective older brother to her. The other girls are not happy about it.
- Girlish Pigtails: Fitting with her childish personality.
- Half-Human Hybrid: She is formed from Tenchi and Yuzuha's DNA.
- Innocent Fanservice Girl: What's wrong with taking a bath with daddy?
- Kid from the Future: She shows up out of the blue one day calling Tenchi "Daddy" and forming a Laser Sword like Ryoko's (and, while inexplicably not noticed by anyone in-universe, eyes resembling Ryoko's as well), although she never explains any details, and Washu can't find the mother from her DNA. Subverted — she was created by Yuzuha, with no actual time travel involved. Tenchi and company were specifically meant to think she was a kid from the future, though.
- Laser-Guided Tykebomb: Created by Yuzuha just to kidnap Tenchi.
- Manchurian Agent: Yuzuha is able to trigger her to take more direct action. It becomes more difficult as Mayuka's personality grows stronger from interacting with Tenchi's family.
- Supernatural Gold Eyes: A trait she shares with Ryoko, not that anyone in universe notices. It's a Red Herring.
- You Gotta Have Blue Hair: Has blue hair.
Noike Kamiki Jurai (OVA 3)
Voice Actors: Naomi Shindo (Japanese), Kari Wahlgren (English), Mona Marshall (English; GXP only)
Formally introduced in the third OVA, Noike was chosen as Tenchi's fiancee by Lady Seto Kamiki Jurai. Ostensibly chosen as Tenchi's bride purely for political reasons, these reasons actually are spying for the Juraian government, and keeping Tenchi's potentially universe-bending harem from spiraling out of control. Over time, however, it seems that she's begun to develop feelings for Tenchi after all.
- Arranged Marriage: Was told to be only a cover-up, but extra omake material has indeed confirmed the engagement as real.
- Berserk Button: Mihoshi. Noike will handle just about any crisis with nary a hair out of place, but the instant Mihoshi tries to sneak an extra croquette from the dinner table Noike flies into a rage.
- Drives Like Crazy: Apparenty, she does.
- Expy: Of Kiyone from the Universe and Tokyo continuities. The responsible attitude, the partnering with Mihoshi, the hair color — just about everything about her is Kiyone in a different body.
- Fair Cop: Was partnered with Mihoshi for a while.
- Harem Nanny: Forcibly inserted into the harem purely for her ability to keep the other girls in line. Once Noike arrived, fights between the girls died down considerably and everyone started chipping in with the chores.
- Hello, Nurse!: Has formal training as a nurse, and takes care of Tenchi while he's sick.
- Jack-of-All-Trades: Former cop, trained nurse, doting housewife, and Juraian spy.
- Last Girl Wins: Politcally speaking, Noike is the last girl introduced to the Harem, and the first to actually be get engaged by Tenchi (not that anybody bothered to ask his permission). Luckily for the other girls, Jurai standards will allow them to STILL be with Tenchi, and even marry him as well when they are ready in the future.
- Perfectly Arranged Marriage: She fits right in with the circus — Seto's never wrong in her Matchmaker hobby.
- You Gotta Have Blue Hair: Teal or green hair, like Kiyone
A slightly modified clone of Ryoko. The only visual differences are a pair of crescent-shaped scars on her cheeks, and a different-looking energy sword. Her personality is radically different, though, being far gentler and more conventionally feminine.
- Cloning Blues: Initially.
- Heel–Face Turn: After Defeat Means Friendship.
- Only One Name: As she is an artificial being.
- Spanner in the Works: In one story of the manga, Washu inflicts Laser-Guided Amnesia on the gang after her Evil Knockoff attacks Ayeka and Sasami and threatens to do the same to Tenchi. As Washu and Ryo-Ohki are heading off to deal with said knockoff, she passes by Minagi and ignores her when she tries to talk to them. This frightens Minagi that she runs off to tell them and she's nearly driven to the Despair Event Horizon when they have no idea who she is. Thankfully, their emotional connection to Washu (and Ryo-Ohki's disappearance) is enough to listen to her and go hunt them down.
- Weak, but Skilled: Relatively speaking. While she's still far stronger than any human and most Juraians for that matter, compared to Ryoko, Minagi is weaker on account of the gems Ryoko draws power from being impossible to copy. You'd never be able to tell when they fight, though, because the centuries that Ryoko spent sealed in a cave, Minagi spent being trained by her "father," one of the most skilled swordsmen in the universe.
- "Well Done, Son!" Guy: Devoted to Yakage and his memory, even after he's dead.
Kiyone Masaki (OVA 3)
Voice Actors: Yuri Amano, Petrea Burchard (English; 1st), Wendee Lee (English; 2nd)
Is the mother of Tenchi and and Tennyo Masaki in the OVA verse.
- Action Mom: She did a lot of things according to the story she left for Tenchi. However it seems most of it was made up.
- Amazingly Embarrassing Parent: When your mother creates an elaborate practical joke concerning her death and wills her relatives to read it aloud to you, she probably qualifies as this.
- Broken Pedestal: Tenchi was disappointed when he found out his mother's true nature.
- Cloud Cuckoo Lander: A surprising twist on the character. Seems to have been aggravated by her advanced age making her senile.
- Composite Character: In universe, Tenchi eventually realizes that many of his memories of his mother are actually composites of the real Kiyone and his Parental Substitute Rhea, who effectively took over Kiyone's role after her death.
- Face Doodling: Is shown doing this to a sleeping Tenchi in a flashback.
- Identical Grandson: She looks exactly like her mother Airi with white hair, and apparently inherits her sense of humor as well: her practical joke about her death involved both Airi and Tennyo. Rhea too, apparently.
- Older Than They Look: Standard fare for Tenchi characters. She died of old age at over 200, though apparently she still had the appearance of a young woman, probably due to her Juraian ancestry. Unlike her father and sister, Kiyone didn't become bonded to a royal tree and may not have visited Jurai at all (considering Yosho was still considered MIA) which is why she died (relatively) young.
- One Steve Limit: Averted, at least across the franchise at large. She's got the same first name as Kiyone Makibi from the Universe continuity
- Passed in Their Sleep: She died peacefully in her bed with the young Tenchi sleeping beside her.
- The Prankster: Which even extended to a post mortem prank on Tenchi.
Azusa Masaki Jurai (OVA and Manga)
Voice Actors: Akio Ohtsuka (Japanese), John Rafter Lee (English; OVA 2), Dave Mallow (English; OVA 3, GXP)Emperor of Jurai and father of Yosho, Ayeka, and Sasami in the OVA verse. While he is officially the most powerful man in the material universe, even he doesn't hold a candle to the powerful women in his life.
- Disproportionate Retribution: In the manga, he wants to kill a boy who had just lifted Sasami's skirt.
- The Emperor: Of Jurai
- Henpecked Husband: Although in name the most powerful man in the galaxy, he is absolutely terrified of the wrath of his wives and his mother-in-law.
- Papa Wolf: Very protective of his daughters.
- Polyamory: Married both Misaki and Funaho. Though he was originally engaged to Misaki of the powerful Kamiki clan, Azusa met and fell in love with Funaho while stranded on Earth. When he returned to Jurai with his new Earthling wife, Azusa was so terrified of Lady Seto Kamiki's wrath that he married her daughter anyway. No one involved seems to have any problem with the arrangement.
Funaho Masaki Jurai (OVA and Manga)
Voice Actors: Rei Sakuma (Japanese), Grace Zandarski (English; OVA 2), Kari Wahlgren (English; GXP), Carmen Disa (Latin-American Spanish)Empress #1 of the planet Jurai and mother of Yosho in the OVA verse. Originally an Earth woman with distant ancestry that linked her to the very first Emperor of Jurai, Funaho cared for the ailing Emperor Azusa when his ship crashed on her planet. The two fell in love, and Azusa brought her back to his homeworld as his wife despite objections from the racist Juraian noble court. Funaho is a calm, collected tactician, prone to never raising her voice. She acts as the Minister of Intelligence for the whole Juraian Empire, and thus always knows more than she lets on.
- Authority Equals Asskicking: She is the Minister of Intelligence for the Emperor and of Jurai. She is also partnered to the 2nd-gen tree Mizuho.
- The High Queen: Her subjects adore her her kind and graceful demeanor. Some of the noble class however...
- Hime Cut: Demonstrates the classic variation, which makes sense since she was born in Feudal Japan when this was the standard style for young women
- Only Sane Woman: Next to Tenchi, she's the most level-headed member of possibly the entire series. She does have her own moments, however, but they are very few and far between.
- Rags to Royalty: From a girl living on Earth during Feudal Japan whose only real connection to the Masakis was being a distant descendantnote , to a Queen of an inter-galactic superpower.
- Reasonable Authority Figure: Doesn't mind so much that Yosho ran away from home and his duties as the Crown Prince, but he could have at least called her.
- Sibling Team: She is the 'brains' to Misaki's 'brawn', and the two consider each other sisters married to the same husband. Bonus points for their respective 2nd Gen ships also being a 'sibling team' as well.
- Yamato Nadeshiko: Probably the most outright example in the whole canon. It helps that she actually is Japanese.
Misaki Masaki Jurai (OVA and Manga)
Voice Actors: Yoshiko Sakakibara (Japanese), Grace Zandarski (English; OVA 2), Kari Wahlgren (English; GXP), Isabel Quinteros (Latin-American Spanish)Empress #2 of Jurai and Mother of Ayeka and Sasami in the OVA series and manga. While seemingly a scatterbrained, overly doting mother, everyone on their homeland seems to be terrified of her superhuman strength and unstoppable wrath. She was originally the Emperor's intended bride, as her family represented one of the most powerful noble clans in the entire Empire. However, when Azusa returned from his travels abroad with a new Earth wife in tow, he married Misaki anyway rather than face her wrath or the wrath of her mother.
- Action Girlfriend: To Azusa.
- Action Mom: Natch. When she was younger, she managed to climb the insanely huge, 5 km tall Tenju tree. She's the Chief Commander of the Jurai Emperor's bodyguards, after all, and invariably snatches all martial arts championships which she can be bothered to enter.
- Amazingly Embarrassing Parents: More in Ayeka's POV than Sasami's, at least in the beginning.
- Arranged Marriage: Supplementary materials reveal Seto arranged her marriage to Azusa, despite her being a child when Azusa was already grown up.
- Perfectly Arranged Marriage: Despite this, Azusa and Misaki seem to genuinely care for each other and the supplementary novels show they were good terms even when she was a child.
- Berserk Button: Don't insult Ayeka or Sasami in front her. Ryoko found this out the hard way.
- Cloudcuckoolander: Apparently thinks that her fling with Yosho, her stepson, (in the novels) is something absolutely normal. Her mother and husband emphatically disagree.
- And there's the fact that when she first sees Ryoko in the OVA, she mistakes her for Sasami. Repeat, she mistakes a well-known criminal for her kid daughter. The only visual similarity between Sasami and Ryoko is that they both have blue hair. It's not even the same shade of blue.
- God Was My Copilot: Or something in the same genre, though in this case it's less "God" and more "Chaos"
- Mama Bear: Do not EVER mock any of her little girls in front of her. Ryoko did it in regards to Ayeka, and Misaki was MOST displeased.
- Superpowered Evil Side: The "Counter-Actor," which is what Misaki will become in the future after both Azusa and Funaho die, which apparently drives her mad with grief. She's powerful enough to take on the Chousin and is only stopped by the future God Tenchi showing up to calm her down
Tennyo Masaki (OVA 3)
Voice Actors: Emi Shinohara (Japanese), Peggy O'Neal (English)
Introduced during the third OVA, Tennyo is the biological sister of Tenchi Masaki and the current head of Masaki village council.
- Cool Big Sis: Once her secret is out of the bag, she wants Tenchi to immediately start calling her 'sister' in every way imaginable and is quite affectionate towards him. She also works hard to keep Airi and other more influential women away from her brother(s), knowing full well what some of them would do to him if they had the chance.
- Cry Cute: Not her directly but she certainly thinks that a crying Tenchi was such. It was enough to make her drop the act of pretending to be their mother when she saw how much Tenchi was affected by it. Later on, she even gushes to Airi about how cute he was.
- Dual Age Modes: Appears either in a mid-twenties form in Jurai or Galactic Union-related circumstances, or as a 80+ granny while dealing with the Masaki village council she's a head of. Her actual age is the second figure.
- Flat Character: Doesn't get much characterization, as she appears only by the end of the third OVA, and doesn't get much exposure in the novels and doujinshis as well.
- Despite being a fairly prominent member of GP, she regularly visits home since she is also the head of the Masaki Village Council which she inherited from Yosho. In other words, any Earth-born Masaki other than her grandfather, father, Tenchi, and the old woman, answer to her.
- Kid with the Leash: In the same way that Minaho is to Lady Seto, she is to her grandmother Airi in keeping the woman in check. She's the only one who can call Airi 'Grandmother' to the woman's face and doesn't care if she gets yelled at since she can keep Tenchi away from her.
- Nice Hat: Wears a spiffy beret in her GXP uniform.
- Older Than They Look: She's 80 years old when she is formally introduced to Tenchi. She's on her way to a class reunion with some of her surviving class members when she drops by to see her brother and also introduce Noike to him.
- Shared Family Quirks: Can't resist a good prank like the rest of the Masaki clan, but is substantially more mellow than all of them, particularly her mother and grandmother. She and Tenchi have a fairly good relationship because of it.
- Smart People Build Robots: Another case of "source material only" info. She is the one that designed the armaments to the original Kamidake. Yeah, ''that'' Kamidake.
- Strong Family Resemblance: Looks exactly like her mom. Who looks exactly like Airi with white hair.
- Theme Naming: Shares a "ten" ("Heaven") element in her name with her brother.
Airi Magma Masaki (OVA3 and GXP)
Voice Actors: Sakiko Tamagawa (Japanese), Kari Wahlgren (English, credited as Renee Emerson in GXP)
Yosho's wife and thus Tenchi and Tennyo's grandmother, Airi is a daughter of the High Priest of the influential Three Lives church worshipping the Choushin, and first met Yosho when he was sent to the Galaxy Academy to let the scandal about his relationship with Misaki to die down. They've got off surprisingly well together, so Seto decided to marry them off for the whole convenience. It helped that this marriage let her sideline the powerful Airai empire, envious of the close relationship the Juraians have with the Choushin. Airi then went to rise off through the ranks of the Galaxy Police to become the Jurai sectoral commander, and is a BFF with the Academy Superintendant Mikami Kuramitsu (not to mention Lady Seto).
- Action Girlfriend: To Yosho, being the GXP sectoral commander.
- Berserk Button: Being called "grandmother", despite having two legitimate grandchildren — only Tennyo is able to call her such without getting the infamous "shark face".
- Comedic Shotacon: Her exasperation of not being able to meet all-grown-up Tenchi due to the piles of paperwork in the fourth OVA is Played for Laughs with the implication that she just wants to bang her own grandson.
- Dating Catwoman: Airaians are the bitter rivals of Juraians, because, as their religion worships the Choushin, they feel that the Jurai unduly grabs them all for themselves. Her marriage with Yosho is still a secret from her own people, and would be a major political bomb had it been revealed.
- Everything's Better with Princesses: Airi is a daughter of the High Priest of Three Lives Church, the main political power in the theocratic Airai empire, which sorta makes her their Crown Princess.
- Heterosexual Life-Partners: The Power Trio of the Great Princesses that basically runs the Galaxy consists of her and her best friends — Mikami Kuramitsu and Seto Kamiki Jurai.
- Innocent Fanservice Girl: She has a great body and sees nothing wrong with flaunting it, cheerfully chatting with Seina in the nude, for example.
- Intergenerational Friendship: It kind of loses its edge with the essentially immortal characters, but Seto is at least a generation or two older than Airi and Mikami.
- Long-Distance Relationship: Because Yosho is essentially stranded on Earth and she has a lot of responsibilities, she can only visit him briefly from time to time.
- Supreme Chef: A trait she picked up from her close association with Lady Seto. In fact, in that little spare time she has, Airi runs an exclusive and very well-regarded restaurant at the GXP headquarter.
- The Prankster: Another trait rubbed off from being a BFF with Seto — or probably a natural one, it's hard to say. Kyone apparently inherited it from her.
- You Gotta Have Blue Hair: Green in her case.
Seto Kamiki Jurai (OVA 3)
Voice Actors: Yukari Nozawa (Japanese), Melora Harte (English)
Azusa's mother-in-law, the head of the arguably most powerful branch of the Jurai royal family, the Kamiki house, Seto is a sarcastic, easygoing woman with the enviable political acumen, snarky wit and impeccable cooking skills — not to mention the impressive fighting ability that makes her The Dreaded among both the Jurai's enemies and its upper circles. Among her close circle, however, she's the loving wife, doting grandmother, and a steadfast friend — just God help you if she chooses you the target of her next prank.
- Action Girlfriend: To the point that her husband Utsutsumi often feels redundant.
- The Dreaded: Goes with her Red Baron title, and space pirates are absolutely terrified of her.
- Everything's Better with Princesses: Or possibly worse, as her title implies.
- God Was My Copilot: Is strongly implied to be the Washu's long-lost best friend Naja Akara. Seto mysteriously appeared in the middle of nowhere with no memory, at the same time that Naja vanished. Since Kagato was an Opposite-Sex Clone of Naja, that would sort of make him Seto's brother.
- Guile Hero: Ayeka admits that Seto is far more powerful than even the Emperor Azusa, in part because she is so adept at forming alliances and twisting the arms of important people.
- Happily Adopted: She's been adopted into the Kamiki house without any usual drama, and gets to be the most powerful person th the Galaxy.
- The High Queen: Princess, actually, but still.
- It Amused Me: Apparently her main motivation.
- Laser-Guided Amnesia: Was found lost and amnesiac in space, and was adopted into the Kamiki family.
- The Man Behind the Man: Gender-flipped. It's her who is a true mover and shaker of the Juraian Empire.
- Manipulative Bitch: Largely for the lulz.
- The Matchmaker: Her main hobby.
- Names to Run Away from Really Fast: Jurai no Onihime, or Devil Princess of Jurai.
- Older Than They Look: Despite her vague thirty-something appearance, Seto is actually at least a couple thousands years old.
- One-Man Army: Just see what she's done with the pirates in GXP.
- Power Trio: One of the Three Great Princesses who actually run the Galaxy
- Red Baron: The Devil Princess of Jurai
- Satellite Character: For all her importance in-story, she appears in the OVA only as a cameo and gets a bigger role only in the spinoffs.
- Supreme Chef: Heavily implied to have taught Sasami
Mikami Kuramitsu (GXP and OVA4)
Voice Actors: Ikuko Sugita (older one), Yoko Soumi (younger one in OVA4) (Japanese), Melodee M. Spevack (English)
Mihoshi's great aunt and the Headmistress of the Galaxy Police Academy, she's a true head of the influential Kuramitsu clan from the planet Seniwa, being the third one of the Three Great Princesses (in addition to Seto and Airi) who actually run the show. Introduced in the GXP as a solemn matriarch in her late middle age, it was revealed in OVA4 that her matronly appearance is just a disguise to hold the unruly cadets in check, and Tennyo even joked that she took the job only to chase after the boys.
- Bunny-Ears Lawyer: Was shown to be a very competent administrator and teacher in GXP, but revealed to be a huge Hard-Drinking Party Girl in her off-duty hours in the fourth OVA series. According to the Word of God, all Kuramitsu are actually like that, always having some eccentric quirk, and the solemn matron from the GXP was actually Nabeshin's idea.
- Comedic Shotacon: In a proud Kajishima's tradition of risque sexual humor, he's found just another sleazy fetish to push onto his fans. Tennyo might've been joking about her chasing the cadets, but Mikami does have some genuine sexual interest in Seina, as revealed in the latest OVA series, which is all Played for Laughs — note that Seina is 15 years old as of the Rhea and Nobuyuki's marriage.
- Creative Differences: On a meta level, apparently, her matronly side came from Nabeshin when he was the Director of GXP. Masaki Kajishima reportedly hated the direction Nabeshin brought the series to, and wanted to treat Mikami in the same Bunny-Ears Lawyer way as all her other relatives, thus the Hard-Drinking Party Girl in the fourth OVA.
- Dark-Skinned Blond: As is her whole extended family, which is apparently an ethnic trait.
- Dual Age Modes: A 50+ matron in her working hours, early-thirties Hard-Drinking Party Girl off-duty.
- Everything's Better with Princesses: Being the effective head of the most influential family of Seniwa, she's just that.
- Hard-Drinking Party Girl: As revealed in the latest OVA series.
- Older Than They Look: Both her appearances are significantly younger than her real age. Yes, even the 50+ one.
- Stripperific: Her off-duty outfit in the OVA, which basically consisted of a leotard with a Cleavage Window and stockings, with a coat for some basic dignity.
Rhea Masaki (OVA 3)
Voice Actors: Rio Natsuki (Japanese), Mona Marshall (English)
- Artificial Human: The Tenchi Ban 13.8 doujinshi and the 4th OVA anime formally revealed that Rhea is an artificial human from Geminar. She was found by Tenchi's mother Kiyone and adopted into the Masaki clan before becoming Nobuyuki's second wife and Kenshi's mother.
- Happily Married: To Nobuyuki in the the 3rd Episode of the 4th OVA.
- Parental Substitute: To Tenchi after Kiyone died.
- Remember the New Guy : Introduced only in the 3rd OVA as a someone with the long connection to the established characters.
- Wicked Stepmother: Averted with the extreme prejudice. She was so nice that Tenchi's memories of his mother actually latched to her rather than his real Cloud Cuckoolander mom. And when Nobuyuki really got around to marrying her, Tenchi was already all grown up anyway.
Hiwa Takahashi (Manga)
- Playing Doctor: With Tenchi when they were children apparently.
Empress Hinase (Tenchi in Tokyo)
Voice Actors: Yuriko Yamaguchi (Japanese), Brianne Siddall (English)
- I Did What I Had to Do: Didn't exactly like having to seal Yugi away, and even apologizes and sheds tears for her when it's said and done.
Kagato (OVA 1 and Tenchi Universe)
Voice Actors: Norio Wakamoto (Japanese), Michael Scott Ryan (English), John Knuckey (Latin-American Spanish)
Kagato is an unscrupulous and powerful scientist/sorcerer from space with ties to both Washu and Ryoko. He comes to Earth in search of the gems so he can add their power to his own, and is perfectly willing to destroy anyone that gets in his way.
- Animal Motifs: It's more subtle than in Washu's or Clay's case, but OVA Kagato has a theme of snakes going on in his ship and even in his style of hair. The person whom he was based on, Naja, has a snake theme in her name.
- Blood Knight: The Universe version is more interested in fighting Tenchi than conquering anything close to a universe, as he's already taken over Jurai as phase one of his plot. The OVA one, while less so, does seem to enjoy the art of combat
- Blow You Away / An Ice Person: He can create powerful gusts of wind and it starts to snow as soon as he touches down on earth
- Cain and Abel: With Yosho, in Tenchi Universe.
- Cultured Badass: His OVA version is super intelligent, well read and mannered, and just so happens to be nigh unstoppable in combat.
- Deadpan Snarker / Tall, Dark, and Snarky: In the OVA:Kagato: [To Mihoshi] Oh my, oh my...You really frighten me. You see, I've heard much of your heroic episodes in the past. Now, I hear you're overworked and your performance stinks.
Kagato: Is that a term of affection, or do you just not like me?
- And this gem when Ayeka hurls an insult at him while trying to attack him:
- Dub Name Change: Kagato's name is changed to Kayato in the Italian dub due to an unfortunate innuendo involving the character's name.
- Evil Counterpart: To both Washu and Ryoko. Like Washu, he's a Mad Scientist, only he's much more evil. Also, like Ryoko, he's a space pirate with very similar abilities, but whereas she was forced to do evil things and is a Jerk with a Heart of Gold, he's completely selfish and has no qualms about committing various atrocities.
- Evil Sounds Deep: Wakamoto makes this a given, and Ryan pretty much evokes Clancy Brown.
- His universe counterpart is very much an evil Yosho.
- Famous Last Words: "You've won boy."
- Faux Affably Evil: Although his Graceful Loser status may make his affability more than just a front ,at least on some level.
- Genius Bruiser: He's a super genius to be sure, but he's also a very powerful combatant in his own right.
- Graceful Loser: Though moreso in the OVA. He also provides the quote on the trope's page.
- Hermaphrodite: Originally, but split in female and male halves. One of the more strange revelations given by OVA 3.
- All There in the Manual: Makes total sense if one reads the OVA canon novel detailing his backstory. He started out as a clone of Washu's (presumably) dead best friend, Akara Naja, who Came Back Wrong and lacked Naja's playful and carefree personality. The Naja clone fused with a male Ryoko prototype, changed its name to Kagato, and the rest is history. So Kagato is the result of a female clone fusing with a male body. Of course, it would've been nice for OVA 3 to bring any of this up in some fashion...
- Ki Attacks: He can shoot blasts of various sizes much in the same way Ryoko can, only green. In Universe he uses these more in the vein of a Sword Beam
- Knight of Cerebus: In the OVA, things get serious once he appears, and he represents the only real time Tenchi was at risk of dying. Clay and Z have brief moments of tension surrounding them, but they never make the same impression that Kagato did.
- His Universe version fits the trope even better. Things were fairly light hearted until he appeared... he cleanly defeats Tenchi's grandfather, kidnaps Ayeka, and gravely wounds Ryoko. From there, Tenchi is forced into a life or death struggle to rescue Ayeka and save Jurai. Azaka, Kamidake and Ryoko all seem to die but manage to recover.
- Laser Blade: Like Ryoko he can form these out of thin air at his leisure. Kagato Jurai has a dark version of Tenchi's. Both versions resemble large bastard swords, to contrast those of the heroes.
- Like a Badass out of Hell: Kagato Jurai spent some time in "The Darkness of the Universe" after his defeat at Yosho's hands, but he later comes back, even stronger.
- Mad Scientist: In the first OVA, he is a villainous scientist.
- Meaningful Name: In kanji it's basically A God Am I, while in common Japanese it's Heel.
- Only One Name: Although using Jurain naming conventions, his Universe counterpart would be called Kagato Jurai. (and is called such by fans)
- Psycho Prototype: He's (half of) a prototype of Ryoko, but unlike her he's a cruel bastard. He also seems to possess much the same powers as her, and he even seems to have more control and finesse with them. Though because he can't network with the 3 gems the same way she can, he's in fact less powerful
- Red and Black and Evil All Over: Kagato's sword in Tenchi Universe. (In the OVA it's green.)
- Scary Shiny Glasses: In the OV As, he wears shiny glasses.
- Sickly Green Glow: All of his energy attacks and his sword are this in the OVA, In Tenchi Universe, they're Red and Black and Evil All Over.
- Super Intelligence: Likely only the Choushin are more intelligent than he is.
- Super Weight: Level 4 normally. Level 6 with Ryoko's gems.
- Vile Villain, Saccharine Show: Definitely.
Dr. Clay (OVA 2)
Voice Actors: Seizo Kato (Japanese), Wesley Mann (English)
- Animal Motifs: An Octopus, naturally.
- Butt-Monkey: At least to Washu, but he gets a moment where he kills his Ryoko doppelganger for disobeying him, which Washu stops joking around after witnessing.
- High-Class Glass: Which is Ironic, as he is far from classy.
- Kick the Dog: His abuse of "Zero" - an android he created, whom he eventually used to replicate Ryoko. Which had the unforeseen side effect of causing Zero to develop a conscience and feelings of her own, as a result of assimilating Ryoko's memories and her feelings for Tenchi. Clay threatened to destroy her when she began to question his orders, and ultimately tried to kill her when she defied him because she wanted to live with Tenchi.

- Anti-Villain: He's really more petty and vain than evil.
- Crouching Moron, Hidden Badass: As shown in GXP, he's actually a 'very' competent swordsman, he's just a blithering idiot outside of that.
- Sissy Villain: He's a walking Camp stereotype
- Unfortunate Names: Unko, the name of Seiryo's ship. It was the only luck-based name that wasn't claimed already, it means "bringer of fortune." Which works really well for how it looks on paper. Unfortunately, it also means poop. More commonly, in fact. Which works really freaking terribly for actually speaking it aloud.
Misao Kuramitsu (OVA 3)
Voice Actors: Hikaru Midorikawa (Japanese), Tony Oliver (English)
- The Bus Came Back: Shows up again in GXP.
- Dude Looks Like a Lady: Is often mistaken for Mihoshi if one doesn't look closely enough.

- Sissy Villain: Misao actually wears boots with high heels.
Mashisu Makibi (OVA 3)
Voice Actors: Keiko Onodera (Japanese), Lara Cody (English)
- Bodyguard Crush: Elects to work with Misao largely because she loves him.
- Ineffectual Sympathetic Villain: When you get your behind handed to you by a nine year old who up to that point had no previous indication of her martial arts prowless, you've pretty much sunk as far as you can go on the villain scale.
- Love Makes You Dumb: Knows that Misao's plan could lead to war with Jurai...and generally thinks that Misao is stupid but puts up with all of that for love.
- Whip It Good: Has this as part of her arsenal...among other things. They don't do her any good.
- The Worf Effect: The main reason for the easy defeat for Mashisu and her team was just to show off how unstoppable the Masaki household has become.
Z (OVA 3)

- Ax-Crazy: The death of his family drove him to attempt to kill the gods that created the universe.
- Blessed with Suck: He views the power to destroy planets a burden because it was given by the ones responsible of his family's deaths, which is why he wants to kill Tenchi in order to spare him of this burden.
- The Chessmaster: Being the mastermind behind the events of OVA 3.
- Dimension Lord: Can appear in and manipulate all space in the universe.

- Manipulative Bastard: Borders on Magnificent Bastard, and would succeeded if Tenchi didn't turn out to be GOD HIMSELF.
- Nigh-Invulnerability: Much like Tenchi, his Light Hawk Wings are pretty much indestructible by anything on our plane. Even the goddesses cannot destroy him without destroying the universe along with him.
- No-Sell: To Tenchi's powers by surrendering one of his wings for each power.
- Overly Long Name: Why does he go by "Z"? Because his full name is Z-0001332536893. Really.
- Person of Mass Destruction: He is a higher dimensional anomaly, which would give him limitless power by our measuring, despite that the Choushin rank far higher still. He once destroyed most of the Earth and the Moon on a whim, but was going to rewrite time to undo the damage afterwards.
- Power Gives You Wings: Or , in this case, wings give you power. The Lighthawk Wings are nigh unstoppable
- Physical God: Compared to anything on the 3rd dimension at least. Unless they have more Lighthawk Wings than he does.
- Reality Warper: his Lighthawk Wings let him do almost anything, including manipulating time and space
- The Starscream: To Tokimi.
- Story-Breaker Power: He could destroy entire planetary bodies, manipulate dimensions, negate Tenchi's abilities that curbstomped Kagato, and by taxing himself to his limits even caused Tokimi pain. It took GOD Tenchi himself to finally kill him.
- Too Powerful to Live: Although Tokimi resurrected him, and his civilisation, and sent him back thousands of years into the past, to live his life normally with his family.
- Well-Intentioned Extremist: He wanted to stop Tokimi from interfering and killing any more mortal civilisations, including his own parents, and intended to kill Tokimi, save Tenchi from the same fate he suffered, and undo all of the deaths he had caused, including Tenchi himself after he cut off the connection with his higher self.
- You Gotta Have Blue Hair: He has green hair.
Kain (Tenchi Muyo! in Love)

- Only One Name Justified since she's the spirit of the Jurai Tree of Darkness.
- One-Winged Angel: Has one which is a blatant Shout-Out to Chernabog.
- Playing the Victim Card: Part of the moment when she crosses the Moral Event Horizon; after killing her "daughter", she claims that she's in the right because of what Yosho's guards did to her, while mocking Tenchi and friends for grieving.

- Master Swordsman: He works with swords and knows how to use them well.

Brainwash another Jurai official and have him instigate unrest on Ryuten? Check. Personally order your minions to kill the daughter of your rival? Check.

- Artificial Human: She was created as an experiment by the Jurai Royal Family.
- Big Bad: The main antagonist of Tenchi In Tokyo.
- The Chessmaster: She is responsible for all the conflicts that Tenchi and his friends encounter.
- Creepy Child: So creepy she was sealed away by Ayeka and Sasami's ancestor, Empress Hinase. She was, however, fully and painfully aware that Yuugi was just a kid and only did so because she had no other option to save Jurai. Unfortunately she was only successful enough to kick the can down the road about 3500 years.
- Complexity Addiction: Once you learn about her backstory and true motivation, her big plan to Take Over the World is revealed to be unnecessarily complicated.
- Dark Magical Girl: A rare case that is the Big Bad instead of working for one. She is a lonely Artificial Human girl who wanted to have friends, and who went on a rampage through Jurai without truly understanding how much she had hurt the planet, and was sealed away while crying and screaming that she was scared. She's also unusual in that her foil (Sasami) and The Hero (Tenchi) worked together to befriend her and provoke her Heel–Face Turn.

- Morality Pet: Sasami is the only one she shows some affection to. Towards the end, she even kidnaps Sasami so they can be together in their new world.
- Not-So-Harmless Villain: She has her flaws to be sure but you can't forget that she almost destroyed Jurai, and she's one of the few people who can single-handedly hand Ryoko her ass.
