[[quoteright:350:[[labelnote:CLICK FOR HIS GENDER-SWAP APPEARANCE AS "RIKO"]]http://static.tvtropes.org/pmwiki/pub/images/riko_toloveru.jpg]][[/labelnote]]
->'''Voiced by:''' Creator/AkenoWatanabe
->'''Sainan High School:''' 2nd Year
The protagonist and resident ChickMagnet. An ordinary, shy teenage boy who's deeply in love with his long term crush Haruna Sairenji, but has ''the'' worst luck when it comes to love much less telling her how he feels about her. After sulking in his bathtub one night, a sexy naked pink-haired girl emerges from his tub. Turns out that said girl -- Lala -- is an extraterrestrial royal princess from the faraway planet of Deviluke looking for an excuse not to go home, setting off Rito's daily routine of trouble and unintentional perversions which get more and more ridiculous as the series progresses.

----
* AboveTheInfluence: So much so that he can even resist [[CharmPerson Sephie Deviluke]]'s natural allure without issue. She mentions that the only other person to share this iron clad resolve is her husband.
* AccidentalKiss: With Ren. Naturally Rito takes it hard, moreso in the manga, where he beats up Ren for it, starting with a [[DynamicEntry flying kick]] and progressing to a BigBallOfViolence.
** In Chapter 54 of ''Darkness'', he has one with [[spoiler: Haruna Sairenji]].
* AccidentalPervert: Quite possibly a contender for TropeCodifier. Rito is often a victim to streams of otherworldly mischief and chaos around him, such as Lala's inventions, Oshizu's psychic powers, or Celine's pollens. But even without such interferences throwing him around, Rito is already often clumsy enough around women to trip over minor obstacles or absolutely nothing, and when he does, he rarely fails to accidentally reach his hands or face into the breasts or other private parts of any girl in close proximity to him. In "Darkness", his clumsiness becomes even more frequent and violating as well as strangely inventive and surreal. He has shown to be able to accomplish difficult feats, such as reaching his hands or various objects into the clothing and undergarments of girls or partially strip off their clothing, and grab several private parts of several girls all at once, all of which purely by accident. And trying to prevent a perverted accident, will just make the accident worse.
** Several characters such as Nana even lampshade his piss poor luck when it comes to over the top ecchi scenarios. Momo calls Rito's ''ability'' a god-like skill. Even Nemesis is impressed by this (for the wrong reasons)!
** [[spoiler: During his IKnowYoureInThereSomewhereFight with Darkness Yami, he must ''literally'' do that on his own free will, when '''any''' other time would be the end of him.]]
** Doctor Mikado suspects that Rito's strange and godly "acts of god" manifested because of the way Rito extremely restrained himself with the girls, causing his "libido" to accumulate and release in form of accidentally groping girls' bodies and all other perverted stuffs happened so far. She called his act a disease, namely ''Cataplectic Indecency Syndrome''. The more he supressed, the more extreme and unbelievable his next "accidents" would be. His libido can act freely when Rito's own consciousness weakens, and the most prominent example is how he became frisky during his sleep, molesting Momo in the process. According to Mikado, his disease is incurable, and she told him to live with it.
** Currently the Pantheon God of Accidental Perverts
* AccidentalProposal: Played completely straight in the first anime series (never happen in the manga), combined with ThanksForTheMammary and it's how the story begins. Lala teleports naked into his bathtub, while he's there, winds up with her breasts in his hands, and that's an official marriage proposal for Deviluke.... [[FridgeHorror Which makes one wonder about how she met all her other suitors.]]
* AllergicToLove: Even touching a girl's "parts", just thinking about Haruna in a swimsuit or seeing a naked girl will freak the hell out of him and send him running away. He gets a lot better as time goes on, but is still liable to freak out if it goes too far.
** In regards to Lala, Rito isn't certain if what he feels for her is genuine love or merely lust.
* AnchoredShip: He's well aware of Lala's affections for him (as well as his own to her) and the possibility of the hots the other girls have for him (thanks to Momo), but decides not to act on any of it in the meantime until he is finally able to confess to Haruna. This causes quite a bit of stress for him.
* ArousedByTheirVoice: When a phone is broken and repaired/enhanced by Lala it has the side effect of enhancing his voice so that anyone talking to him on the phone a sensation akin to being fondled and caressed. Yui ends up enduring an entire conversation with him leaving her in post-orgasmic afterglow unable to move or talk. Momo collapses in a heap after ''one sentence.''
* AttractiveBentGender: [[http://www.mangahere.co/manga/to_love_ru/v12/c101/1.html Very]] [[http://www.mangahere.co/manga/to_love_ru/v12/c101/3.html much]] [[http://www.mangahere.co/manga/to_love_ru/v12/c102/4.html so]].
** Whenever Rito is "Riko", this unfortunately has the side effect of his best male friend lusting after him/her.
* BalefulPolymorph: A RunningGag in the series is that Rito is constantly getting transformed into different shapes or things, whether they be animals, objects, or different sizes due to Lala's inventions; whether or not it was a malfunction or an accident.
* TheBeard: Lala initially uses him as a fake fiancé, but when he tells her she shouldn't marry someone she doesn't love (him) she takes it as him understanding her situation of constant marriage meetings and falls for him for real.
* BeneficialDisease: According to Mikado in chapter 66 of Darkness, Rito's near constant "accidental" pervert situations result from an incurable disease of alien origin. While Rito doesn't see it as "beneficial," every girl in his harem does, including Yami [[{{Tsundere}} though she's not likely to admit it.]] And yes, it's contagious. Several of Rito's love interests already suffer from it.
* BewareTheNiceOnes: While the manga has less emphasis on this, give Rito a good reason and he ''will'' hit you. This was first displayed when Ghi Bree kidnaps and starts molesting Haruna, and Rito attacks him outright. He's shown no hesitation in fighting Ren when the latter [[http://mangahere.co/manga/to_love_ru/v08/c063/3.html attacks him]] or does [[AccidentalKiss something else]] that pisses him off, and on several occasions yells at girls that [[http://mangahere.co/manga/to_love_ru/v07/c056/8.html give him grief]].
* CannotSpitItOut: Part of his problem with the fairer sex.
** At the end of the original manga, [[spoiler:Rito ''finally'' has the guts to confess to Lala his true feelings for her and she encourages he do the same to Haruna. Just as he's about to confess to the girl of his dreams, Oshizu accidentally undoes Haruna's top from afar causing her to run away in embarrassment. Having come this far, Rito goes ahead and shouts the three magic words ''to a group of girls who like him to varying degrees''. He later sulks about this in the bathtub despite quickly explaining he meant he loved ''the pool'' to said group]]
* CatchPhrase:
-->"It's not what it looks like!"
* CharacterizationMarchesOn: He began the story as a guy who couldn't even ''think'' of Haruna in a swimsuit without overheating, fainting, and nosebleeds. By the time the ''Darkness'' series comes around, he's only mildly annoyed with Nemesis manifesting in a way that makes it look like she's auditioning for hentai.
* ChasteHero: He's generally more concerned about the hijinks the girls will cast him upon than their feelings for him. With that being said, one has to wonder ''how in the bloody hell'' he hasn't lost his virginity yet. Especially in ''Darkness'' which puts [[HotterAndSexier Rito in even ''crazier'' scenarios that straddle the line with being softcore porn]].
** According to Mikado, his chaste nature is the cause of these scenarios, as he's apparently '''too''' chaste for his own good. The sooner he confesses to Haruna, the better off he'll be for it.
* TheChewToy: Especially if Golden Darkness is involved...
* ChickMagnet: For a dork who couldn't confess to the girl he crushed on day in and day out, having a sexy alien princess come into his life has done wonders for Rito in more ways than one. He has so many girls after him, a good majority of which are royalty, that Momo has decided that it would be much simpler if he just married all of them.
* ChivalrousPervert: Lampshaded. He calls himself a pervert when he realized that he recognized Momo from the shape of her butt (while transformed into a mouse and looking up at her from the floor.)
* CovertPervert: He is one which a bit of a surprise considering he is AllergicToLove to a small degree. First it began with the few and far between {{Imagine Spot}}s centered solely around Haruna, before branching out a bit to include others. By ''Darkness'' he seems to be strangely fine with the 'Harem Plan' and dreaming of naked girls in the bath, or any time one (or more) of the girls makes sexual innuendo, especially Momo.
* CrossdressingVoices: Can be temporarily averted every time he turns into "[[GenderBender Riko]]".
* CursedWithAwesome: Many people on both sides of the fourth wall would love to be able to find themselves in very erotic situations with girls that are quite physically attractive, be able to legitimately call it an "accident" and have those girls fall madly in love with them, as a direct result. Unfortunately, Rito's quite AllergicToLove, and gets quite a bit of UnprovokedPervertPayback too.
* FemaleGaze: Several girls see him naked in ''Darkness''. Momo since the first chapter where both are in the bathtub and Rito gets up suddenly.
* FirstKiss: Ren notwithstanding, with [[spoiler: Haruna Sairenji]] as of Chapter 54 of ''Darkness''.
* {{Flanderization}}: In the first series, his perverted accidents were more often caused by Lala's inventions, rather than Rito's own clumsiness. In the sequel "Darkness", he can hardly take a step without tripping onto a girl in a suggestive position. As a result, this has become his principal hallmark.
** Additionally, Rito's {{nice guy}} personality was nowhere near as prominent in the early chapters as it is today.
* ForgottenFirstMeeting: [[spoiler:Oblivious to the fact that he and Yui, who has just recently remembered, met many years ago.]]
* GenderBender: Happens five times, all thanks to Lala. Complete with the alias "Riko".
* GenreSavvy: In ''Darkness'', it's gotten to the point that when Lala introduces new untested inventions, he forcefully ''confiscates'' them to keep trouble to a minimum. [[YouCantThwartStageOne It malfunctions on him anyway]].
* GoodParents: Unlike his own [[MarriedToTheJob father]], and his [[WhenYouComingHomeDad mother]], he's made damn sure Celine is left wanting for nothing, food, clothing, shelter, or especially affection.
* HatesBeingTouched: Hates it when girls start clinging onto him. This is more due to [[AllergicToLove embarrassment]] than anything else. Lately, though, he starts to improve, and even stood up for Run when Yui chastised her for clinging to him.
** This also extends to the times when he's a she for the rest of the chapter/episode.
* HeavySleeper: Stated to be "wild" when he's asleep according to Momo.
* HotBlooded: Despite being a normal human, he's more than ready to dive headfirst into the line of fire to protect the girls around him.
* IJustWantToBeNormal: Except that's ''not'' gonna happen anytime soon...
* InexplicablyAwesome: While his unique clumsiness with the girls is not exactly a true skill which he would ever be proud of, it's nonetheless become one of his trademark characteristics, the frequency and coincidence of which are nothing less than extraordinary.
** Chapter 66 of ''Darkness'' lampshades this, when [[spoiler: Doctor Mikado is convinced that all of his AccidentalPervert situations are not the disease, but instead '''his natural talent!''']]
* InstantWakingSkills: Rito wakes up fast when Momo or Lala sneak into his bed...sometimes.
* IronButtMonkey: Just how does he manage to recover from all that slapping and/or beating up from various characters?
* LustObject: A male example. All the girls love him, but some of them have also a sexual desire. Especially Momo. She often sneaks into his room and enjoys it when he "plays" with her body while he is sleeping.
* MadeOfIron: More like he's protected by PlotArmor.
* MaleFrontalNudity: Hits Yami with this. Since he immediately falls unconscious, rather that getting beaten up, she re-dresses him, and tries to pretend that nothing happened.
* MoralityPet: Many of the girls in his UnwantedHarem have become better people as a direct result of interacting with him. Yami went from being a cold-blooded, emotionless assassin, to an adorable little {{Tsundere}} who just CannotSpitItOut. Mea actually saved Rin's life despite being introduced as someone who would perform RapeByProxy by using MoreThanMindControl, and even Nemesis has become more mischievous than outright malicious.
* NiceGuy: A veritable saint for not snapping/forcing himself onto one of the (many) hot girls after ''all this sexy extraterrestial insanity''. Sadly, the lengths to which he goes to restrain himself only make his AccidentalPervert situations increasingly outrageous.
** At least several of the girls (Momo and Run at the bare minimum) would have absolutely no problem with Rito "forcing himself" upon them. That's not to say he HASN'T given the idea of having sex with one of the many beautiful girls who like him a thought or two. What he says to Yui in Chapter 4 of Darkness after she says she doesn't mind if he does "shameless things" to her and ''only'' her (although she tries to pass said words off as a joke) pretty much implies this.
* NotSoDifferent: Surprisingly to ''Gid Deviluke.'' To wit, their lists of berserk buttons is nearly identical, they're both so AboveTheInfluence as to be immune to Charmian powers, or just about any form of mind control, and they're both a BadassPacifist, although Gid is a MartialPacifist while Rito is a TechnicalPacifist. Still, it's a good thing Gid found Yami's creators first, as Gid only killed them due to being enemies in a war. When Rito heard what they did to Yami, he wanted them to ''suffer'' first, perhaps so much so that they ''would outright beg for death.''
* SharingABody: [[spoiler: After Nemesis' battle with Gid nearly killed her, Rito offered his body for her to use as a temporary vessel until she recovered her strength. Much to his chagrin, this allows her to take control of his body to say and do things he normally wouldn't such as being openly perverted and jumping Momo to fondle her.]]
* SexGod: Despite being a generally innocent boy without perverted intentions, Rito appears to have sexual talents which he himself is not entirely aware of. Nemesis complimented his "technique" on pleasuring women when she ordered him to massage her shoulders. Momo believes the same thing about him when he fondles her in his sleep, which she greatly enjoys, and has made it a goal of hers to bring out his "inner harem king". Other times, whenever Rito trips and falls into a girl, some of the ways he manages to accidentally touch them seem to overtake them with an overwhelming sense of aroused euphoria before they notice what's just happened.
** Chapter 66 states that this is a result of Rito extremely holding himself back around women, and his accidents are his body and subconscious venting his excess libido. Yes, it's as ridiculous as it sounds.
* TheSoCalledCoward: Rito didn't hesistate to rush in to fight [[http://blog-imgs-40.fc2.com/m/a/r/marushou/20080509184634.jpg this guy]] to protect Haruna and Lala. Sure, Ghi Bree turns out to be a frail weakling with powers of VoluntaryShapeshifting that made him ''look like'' a roid-raging demon, but nobody told him that. In Darkness, he was willing to go up against Azenda the Tyrant, the previous #1 assassin in the galaxy, while protecting Yami and Mikan, and actually (briefly) held his own until Momo came to the rescue.
* SweetTooth: At least twice while he was talking in his sleep, usually whenever unconsciously feeling up the latest girl who sneaks into his bed.
* TalkingInYourSleep: Usually about sweets.
* ThisIsUnforgivable: Though he didn't say it out loud, he definitely believed this concerning Ghii Bree's treatment of Haruna.
* ThisLoserIsYou: Originally, though he does develop as a character over time.
* TookALevelInBadass: The overarching plot in ''Darkness'' has given Rito something to do, rather than being a passive victim of the universe. To wit, he manages to face down Gid Deviluke [[spoiler: for the sake of Nemesis]], Gid's duly impressed.
* TrainingFromHell: Yami credits her near-constant attempts to kill him for coming across this way. Many characters note that he has survived situations no normal human possibly could.
* TranquilFury: It doesn't happen very often, but when he's calm, quiet, and rooted in place, it means he's well and truly ''pissed!'' Ghii Bree was the first to experience this. Had Rito not realized that Ghii is a truly pathetic weakling, Ghii would have been pound into paste, literally, for what the latter did to Haruna.
* TwiceShy: With Haruna.
* UnderstandingBoyfriend: To legendary levels. Although he does have hard limits, and yells at any of his haremettes who go too far, he takes pretty much everything they throw at him in stride, and clearly treasures each and every one of the girls that surround him, regardless of their wacky antics.
* UnluckyEverydude: Has trouble confessing his love to Haruna, then after Lala comes along, he seems unable to go through a day without being an AccidentalPervert and chastised by any girl he happens to fall on.
* UnwantedHarem: '''THE''' shining example of this trope. As of ''Darkness'' roughly 7-8 women all having varying interests in him and theres even a few women who could potentially become part of the harem should circumstances permit.

!!Mikan Yuuki
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/mikan_toloveru.jpg]]
->'''Voiced by:''' Creator/KanaHanazawa
Rito's younger, more level-headed sister, Mikan's ''way'' too mature for an eleven-year-old (later twelve), having learned to take care of herself at a young age and reportedly has hordes of admirers. That being said, accusations are leveled against Mikan by her own friends and peers as to where her true affections lie.
----
* ACupAngst: Like most girls in the cast, she is also aware of her breast size and often feels inferior when comparing other girls' to hers, mostly Lala, although her physique is quite normal for her age. Despite this, she still feels insecure about this, and has developed a positive connection with Nana due to their similar chest-related angst.
* BigBrotherAttraction: The series skirts this trope quite a bit, more so come ''[[HotterAndSexier Darkness]]'', such as telling Rito that they may be NotBloodSiblings just to see his reaction.
* BrainwashedAndCrazy: By Azenda the Tyrant in chapter 6 of Darkness. She recovers when Momo takes down Azenda.
* CoolBigSis: It was far more obvious early in the manga, but the calmer, more rational Mikan served as an "older sister" of sorts to her older brother Rito despite being younger than him. She was the one who listened to him, hung out with him, and she also did almost all the chores and cleaning in the house at first in the manga.
* DudeMagnet: She is continually being asked out by the boys in her class. Unfortunately for the guys, she's a Bro-con in denial. It seems the Yuuki family is God's gift to the opposite sex.
* EroticEating: Official art really likes showing her sucking and licking on ice cream and popsicles.
* GirlishPigtails: In her younger years.
* GoodParents: To Celine. On those rare occasions where Rito ''can't'' take care of Celine, Mikan is the primary one to fill in. Of note, Mikan is Celine's favorite bathing partner, and if Celine ever catches Mikan bathing, she will strip herself and leap into Mikan's arms. Also, Celine's crib is in Mikan's room.
* LittleMissSnarker: Especially when she catches her older brother in a compromising position with either Lala or Momo...
* LittleSisterInstinct: Like a big sister or mother, she would try to protect Rito from sexual temptations, and doesn't like it when girls with more perverted tendencies like Momo and Mea would do perverted things to him. She tries as often as she can to watch out whenever Momo gets the opportunity to be alone with Rito, and even guards his room at night to stop her from sneaking in and sleeping next to him.
* MoralityPet: To Yami. Mikan is essentially the only person Yami truly considers as a friend, and has become willing to put her own life at risk to protect her.
* MagicalGirl: Two of her school friends believe her to be one after seeing her [[http://www.mangafox.com/manga/to_love_ru/v14/c121/9.html chase a criminal with Lala's outfit courtesy of Peke]].
* OnlySaneMan: It's a worrying state of affairs when one of the most mature, down-to-earth kids in town is a little girl who has barely hit puberty. Partially downplayed come ''Darkness'', though, where puberty does hit her hard emotionally.
* SupremeChef: She is a very good cook, and ends up teaching Yami and Mea a little bit as well.
* ThoseTwoGirls: She is seen to have two female friends at school named Sachi and Mami.
* TokenMiniMoe: After Celine, is the youngest character in the cast.
* WiseBeyondTheirYears: As a younger sister, Mikan is widely known for her maturity and reliability for her age. She basically acts as a big sister, wife, or mother to Rito and all who live in her house.
* ZettaiRyouiki: Type B.
----

!!Saibai Yuuki
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/saibai_toloveru_7.jpg]]
->'''Voiced by:''' Creator/KeijiFujiwara
Rito and Mikan's father, who's a manga artist. Rito would sometimes stop by his father's workplace to help draw the finishing touches.
----
* BumblingDad: He seems to have a bit of a goofy side.
* HappilyMarried: With Ringo
* MarriedToTheJob: He lives in his own apartment/studio where he does his work as a mangaka.
* MartialArtsHeadband: Wears a red headband.
* OpenMindedParent: Like Mikan, he is very casual, even amused, with his son's relationship with an alien girl, something Rito finds perplexing about his family.
----

!!Ringo Yuuki
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/ringo_toloveru.jpg]]
->'''Voiced by:''' Creator/SayakaOhara
Rito and Mikan's mother, who works overseas as a fashion designer. From time to time, she returns to Japan to check up on the family.
----
* AmazinglyEmbarrassingParents: Just for the sake of acquiring their "measurements", she has no issue fondling with Lala and Haruna's bodies, and was on the verge of stripping them down before Rito stepped in to stop her.
* TheFashionista: Ringo's profession.
* HairDecorations: A pair of sunglasses.
* HappilyMarried: With Saibai.
* MarriedToTheJob: Normally working overseas, every once in a while she returns home to check up on the family.
* StrongFamilyResemblance: Rito and Mikan got their eyes from her side of the family.

[[folder:Sainan High School]]

!!Haruna Sairenji
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/haruna_toloveru.jpg]]
->'''Voiced by:''' Creator/SayuriYahagi
->'''Sainan High School:''' 2nd Year
The original subject of Rito's affections (and sometimes perverted fantasies), Haruna is the sweet, kind GirlNextDoor of their class. As it turns out, she, too, has unspoken feelings for the boy. When Lala came into their lives, instead of a simmering love triangle she quickly became friends with Lala, and even admits to her that she also loves Rito, a feeling Lala ''encourages''.
----
* AccidentalKiss/ FirstKiss: With [[spoiler: Rito]] in ''Darkness''.
* ACupAngst: Played with -- she's got quite a decent chest, but when the idea that Rito likes girls with big breasts gets planted into her head, she starts getting more depressed and self-conscious. Only after remembering a speech by Rito about how TrueBeautyIsOnTheInside while comforting Nana (herself suffering from a twice-in-magnitude, justifiable case of this) does she snap out of it and regains confidence in herself.
* BettyAndVeronica: The Betty to Lala's Veronica.
* ClassRepresentative: She's representative for a year, then declines to run again. Then Lala and Yui vie for the spot the next year. Haruna wins anyway because no one wants to vote for Lala or Yui. (Yui's a hardass, and Lala [[TheDitz has no clue what she's doing.]])
* CovertPervert: One chapter of ''Darkness'' has her fantasizing about [[ItMakesSenseInContext Rito bathing her]]. And by "bathing" we mean heavy petting with sexual undertones.
* CurtainsMatchTheWindow: Haruna has both blue hair and blue eyes.
* DemotedToExtra / OutOfFocus: Haruna began declining in appearances for quite awhile as Yui was slowly overtaking her spotlight. Understandable, considering the fact that by this time in real-life Kentaro Yabuki's wife, who served as model for Haruna, divorced him, triggering his CreatorBreakdown that eventually resulted in the cancellation of the original series.
** Though in more recent chapters of ''Darkness'', she is getting the occasional DayInTheLimelight again.
* GirlNextDoor: Very much so.
* GrievousHarmWithABody: While trapped in a haunted house and confronted with the prospect of being raped, an adrenaline and fear-fueled Haruna picks up Rito and tosses him into the monster.
** Haruna's typical reaction to anything threatening is to pick up Rito and use him as a hammer. On one occasion, it [[http://www.mangafox.com/manga/to_love_ru/v02/c016/11.html creates a tornado]].
* HairColorDissonance: Early in the manga, Rito describes her with black hair; subsequent recoloring changed it to dark purple.
* HairDecorations: She always wears a red vertical hair clip on the left of her head.
* NakedApron: In Chapter 42.5 of the ''Darkness'' manga during her ImagineSpot of cooking for Rito.
* NotHerself: A rather frequent victim of this. Over the course of the series, she successively freaks out from fear and starts using Rito as a weapon, becomes a GenkiGirl when possessed by Oshizu, turns into a sadistic AlphaBitch because of an alien medicine, and in ''Darkness'' gets drunk on a Devilukian soda, [[InVinoVeritas making her much more forward toward Rito.]]
* NiceGirl: In contrast to Lala's {{Genki Girl}} and Yui's {{Tsundere}} tendencies. Haruna is also a very kind, understanding and patient person, to the point that she's polite to everyone around her, especially to Rito. Despite his perverted clumsiness, she always forgives him in time.
* OnlySaneMan: In her family, between her sister misreading events between her and Rito and her parents being SickeninglySweethearts. In ''Darkness'', she's obviously humiliated by her parents' chatter while stuck together with Rito.
* RedOniBlueOni: Blue Oni to Lala's Red.
* ShyBlueHairedGirl: It is her genuine wish to be with Rito, though her shyness and his clumsiness stand as the obstacles for her to advance.
* SingleTargetSexuality: She love Rito since from middle school.
* SingleWomanSeeksGoodMan: Haruna first took notice of Rito existence when he won the school festival for his class, and she has realized and remembered that he must be a kind person since she noticed him taking care of the flowers at school when they were neglected by others.
* WhyDidItHaveToBeSnakes: She has a severe fear of ghosts and the supernatural with the exception being Oshizu, but only for a while. When frightened, she has a habit of grabbing the nearest thing around her typically Rito and swinging wildly, in an attempt to get rid of whatever frightens her.
* YouGottaHaveBlueHair: Has blue hair.
----

!!Yui Kotegawa
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/yui_toloveru.jpg]]
->'''Voiced by:''' Creator/KaoriNazuka
->'''Sainan High School:''' 2nd Year
Head of Sainan High School's Public Morals Committee, Yui is seemingly obsessed with everything being proper and decent. Much to her displeasure, most of Rito's troubles has dragged her along with him. Thanks to spending time with him, Yui admits she can't deny she has some affection for Rito, but develops an exceptional case of "CannotSpitItOut".
----
* AccidentalMisnaming: A common gag is that some characters cannot remember Kotegawa's family name, calling her "Kokegawa" instead.
* AccidentalPervert: Come Darkness, and she has caught Rito's now contagious "godly falling technique" causing her to pull his pants down and plant her face right in his crotch, in full view of Risa and Nana... She's suitably horrified.
* AscendedExtra: Following a certain point in the first manga, Yui was given increasingly greater exposure even as [[DemotedToExtra Haruna appeared less and less]].
* ButtMonkey[=/=]TheChewToy: Initially, the harder she tries to keep order, the more screwy fate treats her. Seriously, just how many times has she been involved in Rito's... accidents?
* BuxomIsBetter: As [[LovableSexManiac Risa]] thinks of her. She telling Yui that she should appeal to boys using her chest.
* CannotSpitItOut: Much like Rito, Yui cannot be honest with her feelings.
* CatchPhrase
-->"How shameless!"
* CharacterDevelopment: After going through DefrostingIceQueen. As the series goes on, her {{Tsundere}}, and CovertPervert, traits really start to take over.
* CharacterExaggeration: Anime first series make her seems a real bitch, in her first introduction, compared to manga. In the episode she beleaves that Rito is cause of all the inapropriate actions happening in school and persuad the Principal to punished him by forbbiding him from making any contact with girls for two weeks, also outside school. Just at the end, she notices how wrong she was and that Rito is a kind person.
* CharacterizationMarchesOn: In her debut chapters, Yui played up the straight man to the otherwise wacky cast's antics; a stern girl who believed in rules and ideals. Come the end of the original manga, she's used as the comic relief/guinea pig for various perverted situations. And by ''Darkness'' she's no less odd/wacky than the rest of the cast.
* ClingyJealousGirl: Being a tsundere, this is natural. She hates seeing and hearing about Rito's accidents with other girls. When she hears that Risa took Rito up to the roof, she ''sprints'' up several flights of stairs in short order to reach them.
* ControlFreak: An extreme example. One chapter shows her giving demerits for every wrongdoing of her classmates. This even extends to her household, where she hounds her older brother for going around shirtless.
* CoolBigSis: To Nana, who sees her as a role model.
* CovertPervert: She protests Rito's AccidentalPervert moments a little ''too'' vigorously, and she's the one non-overtly-perverted cast member who's receptive of Rito's ''attention'', much as she's loathe to admit it. She also often imagine herself married with him and...pregnant.
* DefrostingIceQueen: She initially acts bitchy to both Rito and Lala. Over time, she loosens up a bit and even picks on Rito when he has one of his classic "accidents". This ultimately culminates in Chapter 4 of Darkness where [[spoiler: she finds herself in Rito's room laying on his bed wearing nothing but a button up shirt confiding to Rito that she finally understands that basically boys will be boys even if they do perverted things. She even implies she wouldn't mind if Rito would like to do "shameless things" with her as long as it's ''only her''. Yui then tries to pass off what she said as a joke and even claims it was all a test afterwards when Rito fumbles for the right response.]]
* FanServicePack: Compared to her first appearance, she is considerably more buxom as noted by many characters.
* ForgottenFirstMeeting: [[spoiler:Recently remembered that she already met Rito a long time ago.]]
* GirlishPigtails: As a child.
* GoingCommando: After an incident involving a school thug and Yami (where the latter accidentally cut off her underwear in the process), she is forced into this situation.
* HeIsNotMyBoyfriend: Almost completely in denial about her feelings for Rito, even unto herself -- more so when she makes him chocolate for Valentine's, all the while insisting that it's just "obligatory chocolate", and after imagining herself becoming ''married'' to Rito and eventually ''pregnant''. Right, Yui, you just keep saying that to yourself...
* HypocriticalHumor: Risa notes how hilarious it is that a {{Sour Prude|s}} like her has [[http://mangahere.co/manga/to_love_ru/v13/c115/11.html so curvy a body]].
* IfItsYouItsOkay: What she says to Rito in Chapter 4 of ''Darkness''. In typical Tsundere fashion, Yui tries to ''deny'' being serious about what she said...
* InconvenientSummons: A flashback in chapter 44.5 shows she's been the victim of this due to one of Lala's inventions; she is accidentally summoned by Rito while she is naked in the bath. An event which parodies and deconstructs the Anime's rendition of Lala's first meeting with Rito.
* KindheartedCatLover: Only short of owning one. She even goes window-shopping at pet stores and a lot of her belongings are cat-themed, including a meowing ringtone set to ([[ShipTease you guessed it]]) Rito's number.
* TheModestOrgasm: In one of the bonus chapters from the Darkness series, Yui ends up in a compromising position on a train with a bag containing a vibrating toy pressed up against her crotch. The afterglow in the subsequent scene makes it obvious what happened, but she apparently controlled herself well enough that nobody noticed.
* MsFanservice: Of the human girls, she provide the majority of {{Fanservice}} (unintentionally).
* NotSoDifferent: With Rito of all people when it comes to relationship woes minus the over the top ecchi scenarios.
* OnlySaneWoman: She sees herself in this way. WordOfGod stated that she was introduced for have a character with a common sense in the group.
* ReluctantFanserviceGirl: Almost every encounter with Rito usually ends up with her embarrassed, naked or groped (sometimes all three combined).
* RescueRomance: After Rito saves Yui from a group of delinquents, she develops feelings for him.
* {{Sour Prude|s}}: Frequently chides other students for their "inappropriate" behavior and asserts herself to be uninterested in anything related to sex.
* {{Tsundere}}: A classic Type A. Her default expression in the beginning seems to be a scowl, and Rito is surprised the first time he sees her smile. She even acts tsundere towards a cat in an episode of Motto To Love-Ru.

!!Saki Tenjouin
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/saki_toloveru.jpg]]
->'''Voiced by:''' Creator/AyakoKawasumi
->'''Sainan High School:''' 3rd Year
Sainan High's queen bee who considers Lala her rival. Of course, her numerous attempts at showing Lala up just made her embarrass herself in the end. She has a crush on Zastin, and is dismayed to learn that he's Lala's servant.
----
* AlphaBitch --> LovableAlphaBitch: She initially comes across as the typical bitchy queen bee. Though as her [[ADayInTheLimelight focus chapters]] reveal, [[JerkWithAHeartOfGold there's more to her than just that high-and-mighty attitude]].
* ArtEvolution: Her hair in the original anime was a [[https://53rg10.files.wordpress.com/2008/07/toloveru_08-00.jpg much lighter shade of yellow]] compared to the color seen in today's episodes.
* AttentionWhore: She loves to be in the spotlight. The reason for her initial resentment towards Lala is that Lala receives much more attention from the boys at school.
* DemotedToExtra: While the first series portrayed her as more of a regular character, ''Darkness'' has Saki very rarely appearing. Probably because she is one of the few girls who's very likely to not end up a part of Rito's harem.
* ItsAllAboutMe: She is determined to prove that she is a magnificent person, and even gives herself many different titles as a self-proclaimed queen. She is highly arrogant and believes that no one is greater than her.
* JerkWithAHeartOfGold: While having an arrogant attitude most of the time, Saki has been shown to deeply care about those who are close to her, and throw parties or get togethers which she invites the rest of the cast to on numerous occasions.
* LargeHam: As expected of a pretentious rich person.
* LethalChef: After feeding her servants a meal she made herself they all got sick.
* MsFanservice: In the first series where most of her appearances seem to only serve the purpose of being a victim to the perverted mishaps that surround Rito. Less in ''Darkness'' because she is DemotedToExtra.
* NoblewomansLaugh: She has a proverbial laughter that is very stereotypical to her stuck-up personality.
* OdangoHair
* {{Ojou}}: She is a type two: stuck up and prideful, but [[JerkWithAHeartOfGold shows a kind side]] towards people in need.
* OjouRinglets: She has light gold hair that's lightly permed in the back and curled into spirals over her shoulders.
* RunningGag: Things ''never'' go her way when she tries to tell Zastin how she feels about him.
* ShipperOnDeck: Saki supports Rito/Rin and sets up a date between them in chapter 52 of ''Darkness''.
* SpoiledSweet: She is very caring towards her friends, and is polite and grateful towards her domestic workers and guardians, showing a great deal of worry for them and never looking down on them as mere servants or commoners.
* UnknownRival: Saki considers Lala to be her eternal rival, and goes through any means to prove that she is better than her, even though her plans usually backfire and she sometimes ends up naked in the process. Lala remains totally oblivious that Saki holds a competitive grudge against her and considers Saki a good friend of hers.

* ActionGirl: Rin is known to practice Kendo, and is often seen carrying a shinai. She has shown to also have some sharpshooting skills.
* BodyguardBabes: Rin.
* DefrostingIceQueen: Rin has shown kindness and hospitality to Mikan and finds the younger sister to be a lot more reliable than her brother because Rito's clumsiness persists to harass her and Saki. However, after Rito saved her from being possessed by the sword, Bladix, she appears to have changed her impression of him losting her usual composed and aloof self, and she likely has begun to grow affectionate feelings towards him and has earned back her respect.
* FlatCharacter: Compared to Saki, and Rin thanks to her development in ''Darkness'', Aya doesn't have much going for her.
* {{Meganekko}}: Aya.
* PromotedToLoveInterest: Rin joins Rito's potential harem candidates after the cursed sword chapters in ''Darkness''.
* RescueRomance: Rin develops feelings for Rito after he saves her from a cursed sword (with the help of Mea and Yami).

->'''Voiced by:''' Creator/ChiemiChiba (Mio) and Creator/RyokaYuzuki (Risa)
->'''Sainan High School:''' Both 2nd Years
Haruna and Lala's classmates and good friends, Mio and Risa are a pair of [[ThoseTwoGirls inseparable friends]]. Both are more than willing to help their classmates with their personal problems ranging from beauty to smarts, but aren't above doing perverted things to them.
----
* ADayInTheLimelight:
** Chapter 147 of the original series; the only chapter where Risa is the main protagonist.
** ''Darkness'' finally throws Risa another bone with chapter 64 where Nemesis turns the table on her latest attempt to tease her schoolmates, and is now on the verge of [[ShipTease being another candidate]] for Rito's harem.
* BiTheWay: Risa is all but confirmed to be either full blown bisexual, situationally bi, or merely bi-curious. Mio might be in the same boat as well since she too has no problem squeezing other girls boobs just for the heck of it!
** Supporting the theory that Risa in particular might go both ways is that she's not only attracted to Rito in general, (though she could just be teasing him) but also his "Riko" persona has definitely ''not'' gone unnoticed (nor untouched for that matter) by Risa.
** In an extra chapter of Darkness, Momo hangs out with Risa during the weekend and ends up showering at her place after getting covered in both drink and food curtousy of Run and Kyuoko running away from the perverted principal of Sainan High. While in the middle of her shower, a naked Risa barges in and offers to help clean Momo's back which quickly devolves into the former appearing to have her way with the latter. Geez, it sure looks like Risa knew what she was doing huh?
* FanServiceWithASmile: Mio works at a maid cafe as a waitress and Risa is always coming there.
* GirlishPigtails: Mio hairstyle.
* GoodBadGirl: Risa is somewhat implied not to be a virgin, and seems to ''really'' know what she is doing when trying to get Rito to have sex with her... All said and done, that fact doesn't stop her from being a bright and good-natured girl who cares about and looks out for her friends.
* {{Meganekko}}: Mio; may overlap sometimes with ScaryShinyGlasses.
* NotSoAboveItAll: Risa has always played as TheTease to get a reaction out of the people she interacts with, but the moment Nemesis takes control of Rito to push forward against Risa's latest tease in chapter 64 of ''Darkness'', she is shown to be confused, and [[ShipTease turned on]] at Rito's possible forwardness.
* LovableSexManiac: Both Risa and Mio have no problem with touching other girls' breasts.
* SatelliteCharacter: Mio is [[FlatCharacter rarely ever seen on her own]] without Risa.
* SkinshipGrope: Both are just too happy to "feel up" other girls, but Risa does it the most out of the two.
* TheTease: Until Momo appears, Risa was the official user of this trope for the series. One particularly memorable scene has the girls discussing beauty tips. When Risa asks Rito for his opinion, he states that TrueBeautyIsOnTheInside. Risa responds with [[http://www.mangahere.co/manga/to_love_ru/v13/c115/9.html this]]. In another instance, she teases Momo while in the shower, causing her to freak out and bail. She regrets overdoing it, but cheekily notes how similar Momo's reaction was to Rito's.
* ThoseTwoGirls: Mio is almost always seen with Risa while Risa has some chapter where she is whitout Mio.

!!Oshizu Murasame
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/oshizu_toloveru.jpg]]
[[caption-width-right:350:Ghost Form || Artificial Body]]
->'''Voiced by:''' MamikoNoto
->'''Sainan High School:''' 2nd Year
A 400-year-old ghost wandering an abandoned school building, Oshizu was mistaken to have been haunting the place (in reality, it was extraterrestrials trying to find a place to live). From then on, she moves freely around the school campus; in addition, Mikado-sensei creates her an artificial body (with the same face and hairstyle as her original form) for her to inhabit. Oshizu begins working as an assistant nurse to pay off the expenses for her new body.
----
* BigDamnHeroes: [[spoiler: Manages to free Mea from Nemesis' control in ''Darkness''.]]
* CastFromLifespan: Despite already being ghost, her psychic powers require her mental energy to be used. If she were to exhaust all of it then she would cease to exist.
* ChekhovsSkill: In one of the earlier ''Darkness'' chapters, she uses her PsychicPowers on Mea and subsequently enters her mind. Later, [[spoiler: she uses those same skills [[LiteralSplitPersonality to free Mea]] [[EnemyWithout from Nemesis' grasp.]].]]
* CuteGhostGirl: Initially. She gets an artificial body later on, but she is still basically just possessing that body.
* FishOutOfTemporalWater: Having remained within the old school building for four centuries, Oshizu was rather ignorant of modern Japanese culture (such as why BuxomIsBetter) and is fascinated by technology. In fact, the concept of dieting for the sake of getting thin is a BerserkButton for her, since she lived during times of poverty and famine.
* GivingUpTheGhost: She tends to leave her artificial body when scared or hit.
* HeroicSacrifice: Tried this when her powers lead to the Lala's inventions malfunctioning and causing its power source (a tiny black hole) to risk destroying the school, an act that would have likely made hr exhaust her mental energy and cease to exist. Luckily for her, Mea prevented this from happening.
* HimeCut
* JourneyToTheCenterOfTheMind: Can pull this off to those she possesses. [[spoiler: Which she later uses on Nemesis to free Mea.]]
* PsychicPowers: After being a ghost for so long, Oshizu developed decent telekinetic abilities. Unfortunately, her powers can go out of control when she's frightened. Over using them can actually threaten her life too.
* ShipperOnDeck: Supports Haruna/Rito.
* SuperpowerMeltdown: When she's scared, her poltergeist-like powers will go berserk. Given the nature of the series, her powers always go berserk in a way that generates {{Fanservice}} and [[AccidentalPervert makes Rito look like a pervert]].
* [[WhyDidItHaveToBeSnakes Why Did It Have to be Dogs?]]: The easiest way to trigger a SuperpowerMeltdown.

Rito's "best" (for want of better description) friend since junior high, Kenichi is envious of Rito for all of his AccidentalPervert situations. He does, however, especially in the earlier chapters, support Rito/Haruna and sometimes goes out of his way to arrange time for the two to be together.
----
* ADayInTheLimelight: In two episodes of the anime first series.
* AnimeHair: He has black spiky back hair, most of which is pointing back.
* BromanticFoil: He's there [[PluckyComicRelief just to be the envious friend]] that is jealous of Rito's ever growing harem. His CasanovaWannabe antics are also the exact opposite of Rito when it comes to trying to impress girls.
* ButtMonkey: In an omake, Saruyama tried to imitate Rito's "incidents." Sadly...he falls on [[DirtyOldMan the principal]].
* CasanovaWannabe: Envies Rito's popularity with girls, and has no luck finding a girlfriend of his own.
* DemotedToExtra: Gets pushed to the background when ''Darkness'' comes around. The few times Saruyama ''does'' appear are usually just brief cameos.
* GreenEyedMonster: He can be really jealous of Rito (along with almost all the boys in the school) because of how close he is with a lot of pretty and popular girls.
* InterspeciesRomance: Only in the first anime with an unnamed cat-like woman alien who saw him as a perfect father for her child.
* LovesMyAlterEgo: Fell in love with "Riko", Rito's [[GenderBender genderbent]] version.

----
* {{Bishonen}}: The pretty-boy of Sainan High School.
* ButtMonkey: Despite his good-looks, he can never impress anyone, which always depresses him after getting rejected.
* CasanovaWannabe: Tries to get with every girl he comes across, but fails each time.
* ChuckCunninghamSyndrome: Now to be fair, Taizou was never that much of a noteworthy character to begin with, but even then, he's an actual named person that made appearances on occasion. However, after his early appearances, [[WhatHappenedToTheMouse he just seems to drop off the face of the earth]]. It wouldn't be that surprising at all if you've forgotten that this character even existed at this point.
* EverythingsBetterWithSparkles: Goes with the whole {{Bishonen}} look that Taizou has going on.
* ThePeepingTom: Motemitsu is a closet pervert having taken shots of girls changing. He was once found out (accidentally by Rito that has mistaked him for an alien) taking photos of girls in the swimming pool during a swimming class, and was suspended from school for two weeks.

----
* TheDividual: Pretty much the entire club is all the same character. The biggest difference being that Nakajima is the leader of the club in order to give the group some realm of existence.
* {{Expy}}: The TLR version of Megane from ''Manga/UruseiYatsura''. A boy with glasses that leads a fanclub of an alien princess, and hates the male main character.
* {{Fanboy}}: A major one towards Momo.
* GreenEyedMonster: Due to Rito getting along with Momo, as well as the friendly atmosphere he has with many other females of the school, Nakajima, and the club, hates his guts.
* InstantFanClub: The head of a fan club dedicated to serving Momo. They even surround Momo to make sure that people talk through the club members first before being allowed to speak to Momo.

----
* AbhorrentAdmirer: Especially to Yami, who happens to be one of the strongest females in the series who doesn't tolerate perverts.
* ButtMonkey[=/=]TheChewToy: The biggest in the series. His only role is getting beat up by the female characters when he dashes towards them.
* DirtyOldMan: Frequently seen with porn magazines in his hands, and he will happily strip himself and chase any of the teenaged girls he sees.
* EveryoneCallsHimBarkeep: His real name is unknown.
* FatBastard: PlayedForLaughs, of course.

The homeroom teacher for Class 2-A, which is Rito's, and most of the main cast's, classroom at Sainan High.
----
* CharacterTics: He's always shown to be shivering.
* FlatCharacter: He's a minor character with no focus except for the need of a teacher in the 2-A classroom setting of the series. His personality is also relatively unexplored apart from being incredibly unassertive towards his class, which causes him to constantly shiver, and lose control of his students.
* IWasQuiteALooker: It was shown when he was sprayed by the Modori Skunk that he was a handsome man when he was younger.

[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/lala_toloveru.jpg]]
->'''Voiced by:''' Creator/HarukaTomatsu
->'''Sainan High School:''' 2nd Year
The runaway crown princess of Deviluke, having had enough of her father, Emperor Gid Lucion, forcing her into several {{Arranged Marriage}}s, Lala first appeared on the scene by accidentally (or rather, ''conveniently'') landing in Rito's bathtub... while he was in it. She winds up getting engaged to Rito, deeming him suitable enough to be her fiancé, though this was only to escape her father and her bodyguard Zastin. Eventually, Lala does genuinely come to love him and even encourages Haruna's love, despite the fact it interferes with her own.
----
* BadassAdorable: Sweet, good-natured and sunny she certainly is, so it's ''very'' easy to forget that she also belongs to a race of world-destroying warriors... who can fight the galaxy's best assassin to a standstill in ''unarmed combat'', and taking on an AmazonBrigade empty-handed until they figure out her "weak point".
* BadassPrincess: Can put up a hell of a fight against the likes of Golden Darkness when push comes to shove.
* BettyAndVeronica: The Veronica to Haruna's Betty.
* BewareTheNiceOnes: Sees an assassin come after her fiance? Let's make friends with her! Still, she does have limits. In the anime, she hits the rocket boy StalkerWithACrush so hard, he's sent flying into space, crashing head-first on a planet light years away, and the only reason she doesn't literally pound Laposcopo into the dust is that the only weapon she has that can harm him is her tail laser, and that would outright kill him.
* BunglingInventor: Lala's inventions were originally made for pranks, and have a tendency to either backfire or succeed in the wrong way. For example, her Warp-kun device can teleport the user(s) - but not their clothes.
* CoolBigSis: Especially in ''Darkness'' where is shown that Momo and Nana have very high respects for their sister.
* CorruptTheCutie: Played with in some chapters. Lala's still her sweet bubbly self no matter what her female friends and peers try to get her to do regarding her relationship with Rito.
** [[spoiler:Surprisingly played straight in ''Darkness'' when Peke reminds Lala about her own personal happiness with Rito. She spends the entire afternoon clinging onto him like she usually does, but Rito naturally doesn't look too much into it. Cue Momo introducing her older sister to an 18+ dating sim and Lala later surprising Rito by teleporting into his bath tub much like she did at the start of the series. Only this time she has a reason for being in Rito's bathroom. That reason being she wants to experiment with kissing. But of course, in typical TLR fashion, things don't go as planned when Rito has another one of his classic "accidents". In the end, Lala settles for giving Rito a kiss on the cheek.]]
* CuteBruiser: Her physical strength (without any inventions or powers) is pure brute force to the point where one punch can cause a shockwave and create a small crater on a wall without making physical contact to it.
* DitzyGenius: Has a wide range of [[GadgeteerGenius quirky gadgets]] she invented herself and gets straight [=As=] in school as soon as she masters Japanese, yet has the emotional maturity of a ten-year-old.
* {{Expy}}: Of Lum from ''Manga/UruseiYatsura''. Both are beautiful alien princesses in love with a human boy. Both have all sorts of inventions that hardly work right or do not work at all. And they both love to cook food that is way too spicy or inedible for humans to eat.
* FantasticArousal: Her tail. When someone touches Lala's tail, she becomes weak and perhaps has an erotic feeling.
* {{Flanderization}}: Goes from being a cheerful, smart girl with some occasional lasps in judgement to more or less a comic relief DitzyGenius, used as little more than as an initiator of wacky inventions that causes the cast to change in the more recent chapters of ''Darkness''. [[spoiler:And then she gets turned into a little kid, making her look as childish as she acts now.]]
* FlyingBrick: She's much stronger, faster, and tougher than Earthlings. Her costume allows her to fly. She is also a GadgeteerGenius. If she wasn't in a HaremAnime show, she would make a good SuperHero.
* GadgeteerGenius: Though just how useful or ''necessary'' they can be is another matter.
* {{Gainaxing}}: The anime manages to focus on Lala's bouncing boobs even when she's completely covered in shadows. That, my friends, is ''talent'' .
* GenkiGirl: Especially in the early chapters where she's the FishOutOfWater.
* GirlishPigtails: Usually wears this style after [[spoiler:she used her full power and regressed to a pre-teen, fitting her new figure.]]
* GreenEyes: Has emerald green eyes.
* HairDecorations: Peke, her companion.
* IdiotHair: [[TheDitz fittingly enough]].
* InnocentFanserviceGirl: Lala doesn't really seem to care all that much about anything like modesty or not being naked all the time, due to being used to having servants around to dress and undress her.
* KiAttacks: [[http://www.mangafox.com/manga/to_love_ru/v09/c072/19.html Or something like that]]. Since the series isn't really {{Shounen}} so to speak, we don't see a whole lot of use.
* LethalChef: Likes to use alien recipes whenever she decides to cook for her fiancé, which he doesn't appreciate.
* MacGyvering: The primary source of most of the "trouble" in the story.
* MakeMeWannaShout: She ''pushed a typhoon off course'' by yelling at it... because she didn't want it to ruin her trip to the beach.
* MagicalGirlfriend: Even if she is an alien, fits perfectly.
* MagneticGirlfriend: Literally, thanks to her [[DraggedByTheCollar magnet]]-[[CrashIntoHello bot]].
* MsFanservice: Stated by Peke to have gotten her good looks from her mother; ''the most beautiful woman in the galaxy period!''. And she has no problem showing off the goods (albeit unintentionally!)
* NamesToRunAwayFromReallyFast: Lala '''[[{{Satan}} Satalin]]''' Deviluke.
* NiceGirl: A sweet, bubbly girl who always tries to help whenever she can. [[spoiler:She's even willing to share Rito with Haruna, so that everyone can be happy. Peke calls her out on this, reminding her that she should also care about her own happiness.]]
* NiceHat: Doubles as a magical wardrobe.
* NonHumanHumanoidHybrid: As it turns out, she and her sisters are half-devilukean, half-charmian. Lala inherited more devilukean traits than her sisters, though.
* OlderThanSheLooks: [[spoiler:Her body regressed to a pre-teen girl's due to using too much power protecting Rito from Darkness!Yami. However, she states that this condition is temporary and only lasts for a short while, as she did not exhaust as much power as her father did.]]
* OneWomanArmy: Though she rarely gets the chance to show it.
* OutOfFocus: In the first half of "Darkness" Lala is more or less a background character.
* ThePowerOfLove: Rito's confession is enough to change her back to normal after her personality was changed by an alien cold.
* PrehensileTail: And it shoots ''FrickinLaserBeams''.
* PrettyFreeloader: Possibly [[AvertedTrope averted]]. Presumably Rito's parents are source of Rito and Mikan's money. They probably save enough on hired help by using Zastin et al that sending a bit more to their kids isn't a problem.
* RapunzelHair: Has long bubble gum pink hair.
* RazorWind: A properly-motivated Lala can throw punches of compressed air strong enough to smash concrete. Since she rarely has interest in fighting, this is just as seldom-seen as the tail lasers.
* RebelliousPrincess: What kicks off the story initially.
* RedOniBlueOni: Red Oni to Haruna's Blue.
* RoseHairedSweetie: Her pink hair reflects her sweet and cheerful personality.
* SecondEpisodeMorning: Second chapter has Rito waking to find her in his bed. Becomes a RunningGag.
* SingleTargetSexuality: She has several suitors, but she want only Rito.
* SingleWomanSeeksGoodMan: Played at beginning. After that Rito saves her (or rather tries to save her) from Zastin and his subordinates and reasons the necessity of love and freedom in marriage, Lala mistakenly assumes that Rito truly understood her feelings and she really does fall in love with him and wants to marry him.
* VaporWear: Supposedly, she dislikes wearing a bra.
* WeaksauceWeakness: Her sensitive tail. If an opponent grabs it, she becomes unable to fight.
* YouGottaHaveBlueHair: Her hair is pink.

! Peke
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/peke_toloveru.jpg]]
->'''Voiced by:''' Creator/SatomiArai
Lala's robotic servant, partner and wardrobe.
----
* AIIsACrapshoot: Averted. Peke may be quite snarky on occasion, but is honest, hard-working, and kind, not to mention completely loyal to Lala.
* EquippableAlly: Peke most often takes the role of Lala's outfit.
* HairDecorations: Peke is one on most appearances.
* LittleMissSnarker: Peke can look like a small human girl, but she's very snarky.
* MyMasterRightOrWrong: Peke will stand by Lala no matter what, even if Peke is snarky about the choices Lala made that lead to a conflict.
* PowerPerversionPotential: Peke ''is'' Lala's outfit and has full control over everything covering Lala's body, and yes, we mean ''everything.''
* RidiculouslyHumanRobot: Peke's ADayInTheLimelight episode in Darkness had her assume a form passable as a small human girl.
* UndyingLoyalty: To Lala. Peke worships the ground Lala walks on, and is honored to serve and protect her. When Peke was kidnapped by an evil alien {{Fashionista}} who threatened to MindWipe her into his loyal minion, what terrified Peke the most was that she'd never see Lala again. [[spoiler: This is one of the few times Rito actually managed to actually beat the alien antagonist with GoodOldFisticuffs.]]

!!Momo Belia Deviluke
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/momo_toloveru.jpg]]
->'''Voiced by:''' Creator/AkiToyosaki
->'''Sainan High School:''' 1st Year
Lala's younger sister and the younger twin to Nana, Momo is rather well-endowed for her age (much to Nana's angst) and the more mischievous of the twins. Both twins fled to Earth to escape their studies back on Deviluke. She has a unique ability to talk to plants. In ''Darkness'' she decides to come up with a plan to "make all the women in Rito's life happy" and calls it the ''Harem Plan''.
----
* AxCrazy: Has a violent side she keeps hidden, and can be a little sadistic when dealing with people who threaten her loved ones.
* BattleAura: Rarely seen, but [[http://www.mangafox.com/manga/to_love_ru/v15/c127/1.html she's got it]].
* BeneathTheMask: Always puts up a smile in front of everyone, when behind the scenes she can be quite [[ManipulativeBastard manipulative]] and [[AxCrazy violent]]. And also ''very [[LovableSexManiac horny]]''. So far, only Nana, and to a lesser extent, Rito, knows of what goes on inside her head. Momo once even expressed regret over being forced to show her violent side to Rito, but not so much with her perverted side. It should also be noted that she mostly shows her violent side [[http://www.mangahere.co/manga/to_love_ru_darkness/c006.5/33.html when someone threatens the people she cares about]]. Under her facade, she's actually a pretty decent person.
* BerserkButton: Violent retribution awaits (s)he who [[ViolentlyProtectiveGirlfriend dares hurt Rito]] ''or'' her friends!
* BreakoutCharacter: Like Yami, Momo was a recurring secondary character, until ''Darkness'' promotes her as a protagonist.
* ClingyJealousGirl: When Nemesis is around Rito. She also doesn't seem too fond of Mea's aggressive teasing as well.
* ADateWithRosiePalms: Once fondled her own tail while thinking of Rito. Until she got interrupted.
* [[EveryoneHasStandards Even Perverts Have Standards]]: As much as she enjoys molesting Rito, Momo's reaction to hearing Nemesis describe how she wants to ''break'' him is equal parts disgust and fury.
* EvilLaugh: Which freaks Rito out.
* TheFakeCutie: Puts on an innocent front to hide her true personality. Only a few characters, such as her twin sister Nana and the [[WiseBeyondTheirYears mentally mature]] Mikan, can see through her façade. This is not exactly a ''bad'' thing, mind you.
* FanservicePack: She has become noticeably bustier between her introduction in the original series (where she was more or less on par with Haruna) and the latest chapters of Darkness. May be justified by still being growing.
* FantasticArousal: Her tail. She may take full advantage of this [[ADateWithRosiePalms by fondling it]] while fantasizing about Rito.
* ForHappiness: The basis of her "Harem Plan" is to make sure everyone who loves Rito gets a happy ending, herself included.
* GamerChick: Playing games has apparently become one of Momo's hobbies. She has a particular interest in gal games, [[ShoutOut and thinks that they'll]] [[Manga/TheWorldGodOnlyKnows help her get Rito girls]] for the "Harem Plan".
* GenreSavvy: Granted her knowledge comes from dating sims, but her methods concerning the Harem Plan actually work for the most part. The only problem being Nemesis trying to have Rito all to herself.
* GoodIsNotSoft: When facing down Azenda the Tyrant, she summons plants that shoot seeds with the force of cannonballs, and "accidentally" misses a shot, right next to her head, and then denies showing Azenda any mercy.
* GuileHeroine: She manipulates people in order to get what she wants, but is still one of the good guys. For example, her "Harem Plan" is not actively malicious. [[ForHappiness Quite the opposite]], in fact.
* HaremSeeker: A rare inverse version in ''Darkness'', where Momo, herself a harem girl, is doing this not for herself, but for Rito. And oddly, she even wants to add girls who have shown no interest at all in Rito to the harem (even including Saki, the only girl with a clearly-stated romantic interest in a guy ''other'' than Rito). That said, one of the reasons she wants this to work is because she doesn't think she had a chance to be with Rito otherwise. [[spoiler:That's starting to change.]]
* HiddenDepths: At first glance, she's a [[TheCutie sweet, kindhearted princess]]. [[BeneathTheMask Beneath that facade]] she's horny, manipulative, and has a serious violent streak. As ''Darkness'' progresses, however, we get to see more and more of her personality, and she's a surprisingly complex character. Her love for Rito is ''very'' genuine, and she's actually shown some hesitation when it looks like he's starting to respond to her advances. In addition to this, her violent side tends to come out only when someone threatens her friends and family. Even her "Harem Plan" is intended to give the [[AccidentalHarem various girls crushing on]] [[ChickMagnet Rito]] a happy ending with him. She may just be ''acting'' like TheCutie, but she's undoubtedly a good person.
* HornyDevils: Not a devil per se, but a ''very'' naughty alien princess. Plus, she has a devil-like tail.
* IfItsYouItsOkay: Even Rito's "[[GenderBender Riko]]" persona is not safe from her perverted antics.
* InstantFanClub: One is formed by some of the boys at their school for her. Though she initially thinks it's cute, she gets rather annoyed by them partly because they're often rude to Rito, but also because they take time away that she could be spending with him as well.
* JerkWithAHeartOfGold: No matter how manipulative and naughty she can be, she genuinely cares for her family and friends.
* LittleMissBadass: At the very least, she can dodge punches like [[Film/TheMatrix Neo]], then summon plants to take down her attackers.
* LovableSexManiac: Even moreso than Risa. Her current goal in life is to win Rito's love and affection not just because ''she'' loves ''him'', but also so she can have sex with him. Interestingly though, she totally freaks out when Risa starts to make thinly veiled sexual advances to ''her''.
* MatchmakerCrush: While she actively pursues Rito to hook up with all his girls, his harem, nevertheless, includes herself, as she wants just as much affection from him, finding his "[[LuminescentBlush flushed face]]" cute.
* MsFanservice: Moreso in Darkness, but much like her big sister, Momo's got very nice assets and isn't afraid to tease Rito with what she's got either.
* NamesToRunAwayFromReallyFast: "Belia" is supposed to refer to "[[DemonLordsAndArchdevils Belial]]".
* NonHumanHumanoidHybrid: As it turns out, she and her sisters are half-devilukean, half-charmian.
* NotSoDifferent: Though she would never admit it, Momo isn't that much different from Nemesis in terms of making Rito feel sexually uncomfortable. What separates them is Momo genuinely likes Rito, whereas Nemesis sees him as a "servant"; Momo cares about others besides herself whom she considers friends, while Nemesis is self-centered and tries to make Rito hers (thus undoing the work Momo has put into the Harem Plan) and [[spoiler: activating Yami's true potential as a living weapon via the "Darkness" protocol]].
** More surprising is Momo's very similar to ''Rito'': his fantasies are just as explicit as hers, and when Momo has someone come on to ''her'', she experiences a FreakOut and runs away as he does.
* OhCrap: Has a really big one when she sees [[spoiler: Mea transform into Nemesis.]]
* PervertedDrooling: Occasionally happens to her when she thinks of Rito.
* PinkIsFeminine: Despite her violent tendencies, not only does she wear a lot of pink (as well as having pink hair), but she's very feminine. She can do the household chores, including cooking, at least as well as Mikan can. Mikan had a brief identity crisis as a result.
* {{Polyamory}}: What she's aiming for. Momo doesn't care if she shares Rito with other girls, so long as he loves her too. [[spoiler: At first.]]
* PrettyFreeloader: At first. As of Darkness, it's averted completely. When she's not helping Rito deal with some crisis, she can be seen helping Mikan with the household chores.
* RoseHairedSweetie: Her pink hair contributes to her cute and innocent front. [[TheFakeCutie Don't let her fool you, though.]]
* ShamelessFanserviceGirl: Momo is more than willing to step into the bathtub with Rito, wake him up straddling him half-dressed, etc.
* ShipperOnDeck: Taken UpToEleven with the "Harem plan", where she ships pretty much every girl who's interested in Rito, including herself.
* SingleTargetSexuality: Ignores all the guys who hit on her at school in favor of Rito, even in his "[[AttractiveBentGender Riko]]" form. Taken UpToEleven when he gets transformed into a mouse by one of Lala's devices and she's STILL attracted to him. And she didn't even know it was Rito.
* SingleWomanSeeksGoodMan: She started falling for Rito when she how determined he was to rescue Celine from her apparent illness.
* SpellMyNameWithAnS: Is it "Belia" or "Velia"?
* SupremeChef: She's every bit as good as Mikan in the kitchen. So much so, that Mikan was once afraid that Momo was going to steal away her place in Rito's heart. Momo made it very clear to her that this is not the case, much to her relief.
* TheTease: She regularly sneaks into Rito's bed, asks him where his Ero-mags are, and in one notable insistance pops up between his legs and offers to help him with his love problems. She even freely admits that she wants to be his mistress. And this before ''Darkness''!
* TomboyAndGirlyGirl: The girly girl to Nana's tomboy.
* ViolentlyProtectiveGirlfriend: The most protective among Rito's love interests. When she thought Yami was trying to kill Rito and decided to interfere with their conversation, Yami commented that she could sense Momo's bloodlust. On another occasion, when her [[InstantFanClub fan club]] tried to "save" her from Rito (by shooting him with [[NerfArm Nerf Guns]])... she [[GlowingEyesOfDoom was]] ''[[http://www.mangahere.com/manga/to_love_ru_darkness/c017/38.html not amused]]''. In chapter 6 of Darkness, she showed the world, especially Azenda the Tyrant, precisely why the Deviluke family should be respected, and ''feared.''
* YouGottaHaveBlueHair: Her hair is pink.

!!Nana Asta Deviluke
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/nana_toloveru.jpg]]
->'''Voiced by:''' Creator/KanaeIto
->'''Sainan High School:''' 1st Year
Lala's younger sister and older twin to Momo. Having had enough of their studies back on Deviluke, she flees to Earth to pay Lala a visit (with Momo tagging along). Like Momo's ability to talk to plants, Nana can communicate with animals; unlike Momo, however, Nana finds it hard to believe why everyone around Rito likes him, having witnessed a few "incidents" that proves otherwise.
----
* ACupAngst: Poor, poor Nana. It must be hard to grow up alongside [[BuxomIsBetter Lala and Momo]]. She doesn't take too kindly to any derogatory comments or even things that she could interpret as a jab towards her lack of a bust.
* BerserkButton: Even the slightest implication of her "modest" bust size is guaranteed to set her off.
* CatchPhrase
-->''(Usually at Rito)'' "You beast!"
* CharacterDevelopment: Nana starts off with a very negative impression towards Rito, but begins to show feelings for him after he helps mend her friendship with Mea.
* CryCute: [[http://www.batoto.net/read/_/111322/to-love-ru-darkness_ch21_by_cxc-scans/32 The latter half of]] Chapter 21 of ''Darkness'', when Rito confronted her about her realization of Mea's identity.
* CuteLittleFang: She usually has one ridiculously cute fang showing which makes her even more ridiculously cute.
* ADayInTheLimelight: Her [[CharacterDevelopment character arc]] in ''Darkness'' that revolves around her broken friendship with Mea.
* {{Expy}}: In the manga especially, between her pink twin-tailed hair, tsundere tendencies, "atashi" pronoun, ACupAngst, and a lot of her expressions, you'd be forgiven if you thought [[LightNovel/AriaTheScarletAmmo Aria]] took the wrong door.
* FantasticArousal: Her tail.
* FriendToAllLivingThings: Due to Nana's ability to communicate with animals, she has befriended animals from all across space and kept them with her as pets.
* GenderAndJapaneseLanguage: Aside from using the informal-feminine "atashi" to refer to herself, Nana exclusively uses impolite-masculine Japanese in her everyday speech patterns, up to an including the impolite suffix "-yagaru" (which can is the rough equivalent of "goddammit" or "the goddamn") in her sentences when she is bored or annoyed.
* GirlishPigtails
* NamesToRunAwayFromReallyFast: "Asta" refers to "[[DemonLordsAndArchdevils Astaroth]]".
* NonHumanHumanoidHybrid: As it turns out, she and her sisters are half-devilukean, half-charmian.
* PrettyFreeloader: Played straight. She has yet to be seen contributing anything to the Yuuki household.
* PromotedToLoveInterest: Nana starts to show interest in Rito after Mea's friendship mending chapters in ''Darkness''.
* RoseHairedSweetie
* SecretKeeper: Is aware of Haruna's feelings for Rito, which she never told yet to everybody else. Nana promises to keep it secret until Haruna tells Lala about it.
* ShipperOnDeck: Despite [[BlatantLies not liking Rito]] nor understanding why Lala likes him, she's fond of reminding both Rito and the other girls he ''is'' Lala's fiancé, after all.
* {{Sour Prude|s}}: Similar to Yui's case above (in fact more than once in the manga, they're both seen criticizing Rito at the same time during his AccidentalPervert moments), though hers is slightly more downplayed compared to the former. This also makes her even more of a {{Foil}} to her LovableSexManiac sister Momo.
* SpeaksFluentAnimal: With classic animals.
* SpellMyNameWithAnS: Is it "Asta", "Astar" or "Aster"?
* SummonBiggerFish: Against Laposcopo. When he threatened her, Momo, and Lala with his trademark clothes-dissolving frog, she summoned a giant king cobra. Laposcopo finally got the message that messing with the Deviluke family is a ''very bad idea.''
* TomboyAndGirlyGirl: The tomboy to Momo's girly girl.
* {{Tsundere}}: Type B usually, but totally type A towards Rito.
* UncannyFamilyResemblance: With her hair down, Nana looks a lot like Lala.
* VagueAge: While the twins don't look much older than Mikan (who is twelve years old as of ''Darkness''), they attend Sainan High as first-years (roughly 15). This vagueness is {{lampshaded}} when Yui asks the girls if that is their age. Nana [[HandWave responds by telling her not to worry about it, and the Principal helped them out]], although this doesn't prove anything as one of the Principal's favorite sayings is "It's okay because you're cute".
* WasItAllALie: Suffers an emotional breakdown over learning of Mea's true identity and relation to Yami in Chapter 21 of ''Darkness'', wondering if their friendship was all an act, eventually [[CryCute breaking down crying in Rito's arms]].
* WhatDoesSheSeeInHim: Unable to comprehend why everyone (including herself) is falling for Rito's kind personality. Though she may otherwise deny it to save face, Nana ''was'' grateful for Rito comforting her in her hour of need.
* YouGottaHaveBlueHair: Her hair is pink.

!!Gid Lucion Deviluke

[[quoteright:350:[[labelnote:CLICK FOR GID'S NON-CHIBI APPEARANCE]]http://static.tvtropes.org/pmwiki/pub/images/gidnormal_toloveru.jpg]][[/labelnote]]
->'''Voiced by:''' Hidetoshi Nakamura
Father of Lala, Nana, and Momo, ruler of Deviluke and by extension the entire universe as we know it. He tasks Rito with fending off potential suitors who wish to have Lala's hand in marriage. Should he fail, the mysterious ruler of the cosmos threatens to kill not only Rito, but also ''blow up'' the entirety of Earth. Gid is rather antsy about when Rito will succeed him as king.
----
* AboveTheInfluence: The first creature to look directly at his wife's face without being affected by her inherent charm power.
* AuthorityEqualsAsskicking: In his powered down form, he has to suppress his power even further to prevent the Earth from crumbling under him. Then, we he returns to his full powered form, he fights Nemesis, the strongest known enemy so far, and nearly annihilates her, only moving his arms ONCE.
* CharacterizationMarchesOn: In the first series he appears only as a pervert man that use his child-like appearance to get close to pretty girls, but, in ''Darkness'', when regained his adult physique (after the effect of overusing too much energy that turned him into a kid) his personality seems to shift into more serious one.
* ChildhoodFriendRomance: With his queen.
* ADayInTheLimelight: The Gid vs. Nemesis chapters in ''Darkness''. You finally get to see his true, non-chiby form.
* DirtyOldMan: The only reason (in the manga) why he wants his eldest daughter to hurry up and tie the knot with Rito is so he can look up girls skirts all day long.
* EvilIsPetty: While not ''evil'' per se, should Rito fail in keeping Lala off potential suitors hands who also want to marry her, he will first kill Rito and then ''blow up the Earth''.
* GalacticConqueror: How he became Ruler of the Galaxy. Notably though he is trying to hand the position of TheEmperor off to Rito so he can relax.
* HeroOfAnotherStory: He conquered the galaxy in an effort to bring an end to galactic warfare and what we see of him in flashbacks he appears to be very similar to your average Shōnen protagonist.
* TheReveal: Around chapter 46 or so, Gid personally visits Earth in an attempt to hurry along Rito's "courting" of Lala. Earlier chapters built him up to be a legitimate foreboding threat since Gid only bothered communicating via his voice leaving his identity to be a mystery. While Gid is ''not'' someone you want to mess with, you may be easily forgiven for assuming that a seemingly perverted little kid ''couldn't possibly be'' the ruler of the universe.
* SleepModeSize: Why he looks the way he does. He burned so much of his power in the battles to conquer the universe he ended up in his current form. This happens to Lala later in the manga as well, but for nowhere near as long as Gid and is back to normal within a few chapters.
* PintsizedPowerhouse: Even in his current powered down form he is still a LightningBruiser capable of moving at high speeds and strong enough to blow up planets.
----
!!'''Sephie Michaela Deviluke'''
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/sephie_toloveru.jpg]]
The queen of Deviluke, mother of Lala, Nana, Momo, and the last member of Charmian race.
----
* CharmPerson: It's in her species' [[MeaningfulName name]], after all. Not only does she have the power to bend people to her will with words alone, but any male who looks at her uncovered face will immediately lust after her. Sephie hates the [[CursedWithAwesome latter ability]].
* ChildhoodFriendRomance: With her husband.
* CursedWithAwesome: Her beautiful appearance and voice allows her to affect the behaviour of other people but apparently if someone would see her uncovered face they would turn into ''a Beast''.
* CompellingVoice: Seems to be capable of this. She manages to persuade ''the principal'' to give up on pursuing her without a fight.
* {{Expy}}: Visually, of Sephiria Arks from ''Manga/BlackCat''.
* GoodParents: She cares deeply for her daughters, the reason she came to Earth was [[spoiler:because she was worried about Lala who turned into a small girl after overusing her power in a fight against Yami]].
* InformedAttractiveness: She is described as one of the most beautiful women in the universe. While she is certainly very pretty she doesn't particularly stand out in a cast full of attractive girls and women. The CharmPerson powers might have something to do with it.
* InterspeciesRomance: She is from Charmian race while her husband is a Devilukian.
* LastOfHerKind: She is apparently the last living member of the Charmian race.
* MeaningfulName: The Charmian race is known for it's ability to charm males of any other race.
* OddNameOut: Unlike her husband or daughters, she is named after an archangel, and not a demon.
* SingleTargetSexuality: She has this effect on males of other species. Any male from any species will fall for her if he sees her face.
* SingleWomanSeeksGoodMan: Of a sort. She fell in love with Gid because he was the only male to not be affected by her Charmian powers. When Rito also proves to be immune, Sephie surmises that his unshakable will and convictions put him in the same league as her husband. She then tells Rito that she understands why her daughters fell in love with him.
* SoBeautifulItsACurse: Even says this herself. Not that her power helps.
* SuperpowerfulGenetics: Her younger daughters Momo and Nana have inherited variations of her CharmPerson powers. Momo has an affinity for plant life, while Nana has an affinity for animals. Ironically, the daughter with the strongest physical resemblance to her, Lala, takes after her Deviluke father power-wise and has none of her mother's powers.

!!Konjiki no Yami (Golden Darkness)[[spoiler:/Eve]]
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/yaminormal_toloveru.jpg]]
[[quoteright:350:[[labelnote:CLICK FOR YAMI'S DARKNESS FORM]]http://static.tvtropes.org/pmwiki/pub/images/yamidarkness_toloveru.jpg]][[/labelnote]]
->'''Voiced by:''' Creator/MisatoFukuen
->'''Sainan High School:''' 1st Year
One of the deadliest assassins in the galaxy, Konjiki no Yami ("Yami", in shorthand) was originally hired by one of Lala's suitors to kill Rito, until a slip from his mouth reveals that Rito is not what he seems to be. Nullifying her client's contract, she turns against him and stays on Earth for the time being... all the while starting to have a crush on her erstwhile target herself, even as she continually threatens to kill him one day.
----
* ACupAngst: Subverted. She seems to have a case of this, especially compared to [[spoiler:her biological mother]] [[GagBoobs Tearju]], but she could easily remedy that with her shape-shifting powers. However, she notes that a large chest would be impractical in combat.
* AccidentalPervert: She accidentally grabs [[GenderBender Riko]]'s naked boob, and gets screamed at. Yami is so conflicted over this brief moment of role reversal that she can only react with incredulity.
* ArtificialHuman: Was created to be a powerful bioweapon.
* BadassAdorable: She may be a cutie, but don't go getting any ideas. She is a lethal LivingWeapon.
* BadassBookworm: Spends most of her time reading any book she can get her hands on.
* BecauseYouWereNiceToMe: If Rito had not given her that Taiyaki because he thought she looked lost and hungry when they first met, there's no way in hell he'd be alive right now.
* BerserkButton:
** Anyone/anything she considers perverted. Poor Rito, being the AccidentalPervert he is, is her most frequent punching bag whenever he's in close proximity, even if she ''knows'' his latest mishap was an accident, only stopping short of killing him because she admits that she does know. [[spoiler:Her Darkness persona expresses the opposite opinion and openly embraces her sexual side.]]
** It's also not a very good idea to do anything to Tearju around her. Though that may be because she always catches Rito with her while she's naked...or [[http://manga.cxcscans.com/reader/read/to_loveru_darkness/en/1/10/page/17 in post-orgasmic]] [[http://manga.cxcscans.com/reader/read/to_loveru_darkness/en/1/10/page/18 afterglow.]]
** If you value your life, don't ever threaten Mikan.
* BreakoutCharacter: Originally a secondary character ([[BillingDisplacement not that you'd know from her prominence in promotional materials]]), she gets promoted to a protagonist along with Momo for the ''Darkness'' sequel.
* CatchPhrase:
-->"I hate ecchi people!"
* CharacterDevelopment: Has arguably the most in the series, going from completely emotionless killer to caring for those dear to her. Could also be argued that after her "Darkness" persona was released, and brought back to normal, she became much more emotional when she gets flustered.
* TheComicallySerious: She is usually TheStoic, even when attempting to maim Rito for accidentally molesting her.
* ContinuityCameo: Yami's appearance [[http://www.mangafox.com/manga/to_love_ru/v09/c072/19.html in this scene]] is a call-back to [[Manga/BlackCat Eve]], who was forced into a form like this while she was BrainwashedAndCrazy early in the anime adaptation.
* CordonBleughChef: Her first attempts at cooking were rather horrid, though justifiable by her initial limitation of knowledge of Earth's cuisine to taiyaki, so she just put that in everything. Under Mikan's instruction she does quite well at cooking, but still has a fondness for taiyaki, which she expresses by creating taiyaki miso soup, something Rito had to force down.
* CuteAndPsycho: Her [[spoiler:"Darkness"]] persona, who openly admits to being in love with Rito and wanting to be [[{{Yandere}} together with him forever]].
* DarkAndTroubledPast: She is a living weapon created by Dr. Tearju Lunatique from her own cells (making Yami a clone) who named her Eve and raised her. They lived happily and Tearju planned to run away with Eve but her plans were preempted by the Eden organization which found out about the planned flight and attempted to kill Tearju, forcing her to flee without Eve. Eve was then told that Tearju had abandoned her and she would be trained as a weapon and she was renamed Golden Darkness. Eden was destroyed by the hitman Black, setting Eve free of their control. Before she met Rito and Lala, Yami lived alone in the universe.
* EvilCostumeSwitch: [[spoiler:Her "Darkness" form comes with a much skimpier outfit than her trademark one.]]
* {{Expy}}: Of Eve from ''Manga/BlackCat'', [[Film/Terminator2JudgmentDay The T-1000]] and possibly [[LyricalNanoha Fate Testarossa]]. [[spoiler:As of ''Darkness'', however, Yami is implied to be not just an expy, but an AlternateUniverse version of Eve, which turns out to be also Yami's true name. And like her original, she's an enhanced clone of her creator, Tearju Lunatique.]]
* GirlishPigtails: Her regular hairstyle.
* HairIntakes: The two "cat ears" on her hairdo.
* HeelFaceDoorSlam: [[spoiler:InvokedTrope. Her "Darkness" protocol was designed to activate whenever she gains enough peace of mind to consider a HeelFaceTurn.]]
* HellBentForLeather: Her standard outfit.
* HiddenHeartOfGold: {{Pun}} aside, a major part of her CharacterDevelopment in ''Darkness'' has her mellow out considerably, but not necessarily being honest about it.
* InLoveWithTheMark: How her relationship with Rito ultimately developed. The way the relationship started is the real reason why she loves taiyaki so much.
* LittleMissBadass: She looks only a bit older than Mikan but is one of the strongest fighters in the series.
* LittleMissSnarker: She is quite fond of snarking at people. Momo and Rito are her two favorite targets, more so come Darkness.
* LivingWeapon: What she initially considers herself to be, having been indoctrinated as such.
* MsFanservice: Especially in ''Darkness'' where she is often naked and her incidents with Rito are more frequent.
* NoSocialSkills: In ''Darkness'', she once tries to find a fun topic to ease the tension between her and Rito. After glaring for a bit in thought, which was already giving Rito [[OhCrap the wrong impression]], she starts talking about the ''vital points of the human body''.
* OneWomanArmy: What she was intended to be, and for the most part she lives up to her reputation.
* TheOnlyOneAllowedToDefeatYou: The reason she saves Rito's ass so many times... or so she says.
* OvernightAgeUp: Shapeshifting has its [[http://www.mangafox.com/manga/to_love_ru/v12/c100/16.html many]] [[http://www.mangafox.com/manga/to_love_ru/v12/c100/17.html uses]] as change her bodies size and measurements to look more mature and adult-like. Although she choice to remain in her child-like form is most likely due to the fact that it is comfortable when in combat.
* PersonOfMassDestruction: [[spoiler:The "Darkness" protocol's purpose]].
* PowerPerversionPotential: [[spoiler:Milked for all it's worth in her "Darkness" form.]]
* PrehensileHair: Yami's most notable ability is her control over her hair. She can control its movements, extend it's reach and, combined with her shapeshifting abilities, uses it to create giant fists and dragon heads. She can even solidify her hair to form metallic objects like sword blades, metal teeth, battle axe, spiked maces, drills, hammer, wrecking balls, etc...

* ShamelessFanserviceGirl: [[spoiler: "Darkness" form]] has her be more playful, enjoys ecchi things and seems to be more than openly infatuated with Rito, wanting him to do more perverted things to her.
* ShapeshifterWeapon: his ability gives her the power to change any and all parts of her body into weapons like her hands turning into blades, claws or huge mechanical gauntlets. Yami mostly uses this ability to create weapons from her hair, she has also been shown to create non-weapon objects such a frying pan or even some medical equipment but is still useful against opponents.
* ShesGotLegs: A one-off character remarks how sexy her thighs are.
* {{Stripperific}}: In her [[spoiler: "Darkness" form]] she wears a much more revealing leather outfit with clawed gloves.
* SugarAndIcePersonality: Can go from threatening Rito with his life to acting amiable towards Mikan in a heartbeat.
* SuperpoweredEvilSide: [[spoiler: What her Darkness form ultimately is. Played with in that rather than being outright, pure evil, it is instead extremely perverted thanks to a glitch.]]
* SuspiciouslySpecificDenial: After the [[spoiler: Darkness incident]], with a heavy serving of what is likely {{blatant lies}} on the side.
--> '''Yami:''' ''*Gets'' ''{{accidental pervert}}'d'' ''again, shoves Rito away*'' Why does it immediately turn out like this!? I'll just tell this straight so there are no misunderstandings!! Everything I said or did when [[spoiler: I became Darkness]]!! None of that was my true nature! I...I am not that ecchi!! A...And as for you! ''*[[LuminescentBlush Blushing furiously]]*'' I d-d-don't have any feelings for you!! So...
* TheStoic: She rarely shows any emotion.
* TheseHandsHaveKilled: She says this almost word for word to Rito in chapter 6 of Darkness, right before she and Rito were attacked by Azuna the Tyrant. She was greatly relieved when Rito accepted her anyway.
* TookALevelInCheerfulness: She goes from being a cold-as-ice assassin to slowly accepting her humanity.
* TooManyBelts: Five totally pointless but sexy-as-hell belts wrapped around each leg (the lowest of which are hidden by her shoes). She also has a pair of belts on her ''feet,'' another pair of belts on each sleeve, and two more on her abdomen for good measure. Even in her school uniform she keeps one around her left leg.
* TrademarkFavoriteFood: Taiyaki, and [[BigEater she will eat a lot of it]].
* {{Tsundere}}: Develops into a strong Type A for Rito. With other people, she starts as {{Kuudere}} and later starts to show a Type B tsundere side.
* TykeBomb: Created to be a killing machine, [[spoiler:and to inflict wanton destruction on planetary level by the "Darkness" protocol when the universe is on the verge of achieving total peace]].
* UsedToBeASweetKid: [[spoiler:When she was a child she was downright cute and kindhearted. Unfortunately the scientists who created her had other plans.]]
* VoluntaryShapeshifting: She has PrehensileHair which she can transform into anything and she is a living ShapeshifterWeapon. She is also able to change parts of her body into animal-like features that gives her extra capabilities, growing a pair of white feathered wings from her back similer to an angel, to enable her fight. She can also turn her legs into a fish tail similar to a mermaid with gills that lets her breath and swim better underwater.
* WeaponizedTeleportation: [[spoiler:In her "Darkness" form, she can form portals with her hair to send anyone near her to somewhere else, and instantly summon anyone she wants to her.]]
* WhatIsThisThingYouCallLove: Much like Mea and [[spoiler: perhaps Nemesis as well]] Yami doesn't quite get human emotions and love is one of them. Justified in that all she has ever known her whole life is killing.
* WhenSheSmiles: Quite possibly [[http://www.mangafox.com/manga/to_love_ru_darkness/v01/c005/42.html her most]] [[http://i303.photobucket.com/albums/nn139/animangamania/vlcsnap-2012-10-29-10h14m01s136_zps12174ddc.png lethal weapon]].
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Slimy Tentacles?]]: Loathes ecchi things, especially tentacles. Though the latter of those seems to induce more of a panic in her than her standard response to anything else perverted happening to her. She mentions it being a result of being lost on a planet with tentacled monsters, but trails off quickly, obviously [[NoodleIncident not wanting to talk about it.]]
* WoobieDestroyerOfWorlds: A unique interpretation. In addition to her DarkAndTroubledPast, her "creators" [[spoiler:programmed the nanomachines that give Yami her powers with a "Darkness" mode that activates when she comes to accept the mere possibility of being able to live peacefully, turning her into a living weapon of mass destruction to make sure that the universe will never achieve true peace]].
* {{Yandere}}: In her [[spoiler:"Darkness"]] form, she tells Rito that she loves him, and by killing him herself, he can live on in her heart forever.

!!Mea Kurosaki
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/mea_toloveru_4.jpg]]
->'''Voiced by:''' Creator/YukaIguchi
->'''Sainan High School:''' 1st Year
An alien girl introduced in ''Darkness'', who claims to have been created by the same organization as Yami. She has been sent to Earth on a mission to take her "big sister" back.
----
* ACupAngst: She's beginning to understand how Nana feels after one of Oshihuru's outbursts caused her, Tearju and Mikado to be stripped simultaneously.
* AffablyEvil: Unlike her master, Nemesis, she is genuinely nice to Rito and the others [[spoiler: until her HeelFaceTurn]].
* ArmCannon: One of her transformable weapons, which can fire [[http://www.mangafox.com/manga/to_love_ru_darkness/v01/c004/40.html laser beams]].
* ArtificialHuman: She is Yami's younger sister as she was created by the same organization and from the same project (Project Eve) as her.
* BareYourMidriff: In her combat outfit.
* BecomingTheMask: At first she was friendly toward Nana only for the sake of her Master's plan, but then she realised she really cared for her.
* BewareTheNiceOnes: Seems to be quite nice, but is a very strong and ruthless fighter.
* BiTheWay: Spends a good portion of one chapter groping and/or licking Riko.
* BraidsOfAction: She has red hair with a really long braid.
* CatchPhrase:
-->"Wonderful!"
* CharacterDevelopment: Mea starts off as a sadistic killer hiding behind a fake kind-and-sweet persona whose only goal was to activate the "Golden Darkness" within her sister, Yami. However, the school-setting surrounding Rito, as well as establishing a close friendship with Nana, ended up making her fake persona much more genuine as she ends up becoming more of TheTease to help move Momo's "Harem Plan" along.
* [[spoiler:TheDragon: To her master, Nemesis... who happens to be her split personality.]]
** [[spoiler:TheStarscream: After realizing that she really cared for Nana, and later Rito and the others.]]
* FusionDance: When she was first created [[spoiler:she was mentally unstable and merged with her fellow Transform bioweapon Nemesis]].
* FriendlyEnemy: Unlike Nemesis, she is genuinely nice to Rito, Momo, and Nana.
* GenkiGirl: Is almost always smiling and energetic.
* GirlyRun
* GoodBadGirl: While the rest of the cast balk at the topic of sex, Mea shows great curiosity for it, and will openly talk about her fantasy of getting Rito to lick her, to the point of outright asking him to do so. Otherwise, she's usually a very friendly and upbeat person.
* GrandTheftMe: She can, and has taken control of other people's bodies. Most notably she has done so to Rito repeatedly onscreen. This ability was also useful in rescuing Rin from a literally bloodthirsty sentient/empathic sword.
* HairDecorations: A black pin with a white cross.
* HairIntakes: Her hair has two intakes that look like cat ears.
* HellBentForLeather: Her alternate outfit is a copy of Yami's.
* HaremSeeker: Is in favor of the harem plan and agrees to help, but in her own way.
* HeelFaceTurn: [[spoiler: After realizing she actually cared for Nana and the others, and after her split with Nemesis.]]
* IdiotHair
* JapaneseSiblingTerminology: Refers to Yami as "Onee-chan", [[spoiler: mostly likely as they both have similar powers]].
* LiteralSplitPersonality / EnemyWithout: Subverted. In Darkness chapter 39, [[spoiler: Nemesis explains that Mea is a seperate personality that Nemesis created in order to better adapt being around other people. Because Mea has always appeared to see Nemesis face to face before, she was not aware that she and Nemesis were two minds in the same body, and Mea's personality is currently being supressed by the darkness inside Nemesis. After, Mea speaks to Nemesis inside her subconscious, insisting that Nemesis lied about Mea being her alternate personality and demands her body back. Nemesis explains that when they first met, she was in a physically unstable condition and needed a physical vessel to stabilize herself, and so she fused herself into Mea.]]
* LovableSexManiac: She has made more than one reference to Rito having licked her body or her desire for him to do so, though she makes this out as a joke. However it has been discovered by Oshizu (during her possession of Mea) that this desire is in fact completely genuine.
* PrehensileHair: Mea can control and move her hair/pony tail (like an actual tail) and uses it for most of her transformation abilities like many different shape guns, a clawed hand or a blade at the end of it.
* ReusedCharacterDesign: Mea looks identical to Amane Yuka from Kentaro Yabuki's one shot ''Futugami Double''.
* SecretKeeper: Knows about Momo's "Harem Plan", but despite semi-conflicting orders, has chosen to support it. However, she won't help Momo where it comes to Yami.
* ShamelessFanserviceGirl: Mea doesn't show any kind of embarrassment or shame, not even when her clothes got ripped off. She instead prefers to get caught in awkward and/or sexual experiences, showing a sadomasochistic side.
* ShapeshifterWeapon: Similar to Yami, Mea can shapeshift any part of her body into weapons such as blades. However she is capable of creating many different shaped machines like guns that shoot laser beams powerful enough to easily destroy really strong barriers and a micro-black hole.
* SweetTooth: Mea likes her tea with enough sugar cubes to peak over the top of her cup.
* VaporWear: Flashbacks reveal that she doesn't wear anything under her fighting outfit.
* VoiceChangeling: In addition to her shape-shifting abilities, she can also change her voice to sound just like anyone.
* VoluntaryShapeshifting: Mea can alter the shape and size of her body or parts of it, like making her breasts bigger. Mea can also alter her size to copy the form and appearance of anyone (eg: Tearju), similar to shapeshifting.
* WhatIsThisFeeling
-->"For some reason, my body's getting hot... Could this be what they call an {{ecchi}} feeling!?"
* [[WhatIsThisThingYouCallLove What Is This Thing You Call Friendship?]]: Thanks to Nana playing her Mikan, she learns the same thing that Yami did -- a friend's warmth.
* {{Yandere}}

!!'''Nemesis'''
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/nemesis_toloveru.jpg]]
->'''Voiced by:''' Creator/RinaHidaka
Mea's master who is the closest thing the series has to a main antagonist. She provides her servant orders to observe Yami's current lifestyle in the hopes of one day turning her back into the heartless assassin she was originally programmed to be. Following her battle against Gid, she is now currently [[spoiler:SharingABody with Rito Yuuki in order to regain her stregnth]].
----
* AffablyEvil / FauxAffablyEvil: Can be either at a moment's notice.
* AbhorrentAdmirer: Seems to have become this for Rito almost immediately after meeting him in person due to his ability to face plant into her crotch before she could react.
* AmbiguouslyBrown: She seems to be fairly tan, not really dark.
** {{Retcon}}: She was, ironically, lighter during her frames in the shadow.
* [[spoiler:BigBad: The closest one to this series as of now.]]
** [[spoiler:BigBadFriend: Nemesis makes this offer to the group at large, particularly to Yami. Momo absolutely refuses to GoKartingWithBowser.]]
* BiTheWay: Just ask Momo.
* BullyingADragon: Arguably, with Momo. The moment Yami distracts her Momo nearly takes her head off with a [[KiAttacks "tail laser" attack]] that was [[EyeScream aimed right at her eye]].
* CharacterDevelopment: Nemesis ends up going almost the same route as Mea. Throughout her attempts to revert Yami back to her original personality, she starts to enjoy taking part in the crazy lifestyle that surrounds Rito. [[spoiler: She even grows to becoming a good friend of Rito after he offers himself as a vessel to heal herself after almost dying in a fight against Gid]].
* TheCorrupter: Seems to have shades of this if her talk about "mental destruction" and turning Rito into a sex slave is anything to go on. [[spoiler: Played completely straight when she herself is solely responsible for awakening Yami's Darkness persona.]]
* CurbStompBattle: Gets destroyed by Gid while he barely took her seriously. [[spoiler: Would have died if Rito didn't save her.]]
* DepravedBisexual: Just look at what she does to Rito ''and'' Momo when she introduces herself to them.
* DesperatelyLookingForAPurposeInLife: As a LivingWeapon, she thought warfare was the only thing she's good for. Rito has shown her otherwise, and she's ''very'' grateful.
* EvilCounterpart: To Momo with regards to Rito and their goals relating to him.
* EvilIsPetty: Her primary reason for going after Rito is because Momo wants him. Nemesis admits that she just loves taking things that other people find precious.
* FriendToAllLivingThings: Cats seem to have a thing for her.
* FusionDance: When Nemesis was first created [[spoiler:she was physically unstable and merged with her fellow Transform bioweapon Mea]].
* GirlishPigtails: After getting her kimono.
* GoingCommando: Wears absolutely [[http://www.mangahere.com/manga/to_love_ru_darkness/c024/11.html ''nothing'']] under her dress. Yabuki was only ''too'' happy to drug the censors [[GettingCrapPastTheRadar and show us exactly]] how much ''[[http://www.mangahere.com/manga/to_love_ru_darkness/c024/12.html nothing]]'' she wears.
* GrandTheftMe: [[spoiler: She can usurp Mea's body at any time, with little to no warning. This because Nemesis reveals that, in the past, she was in unstable physical condition and needed to temporarily fuse with Mea to continue to exist. She plans to leave Mea's body after Darkness kills Rito, and then the three of them will be together.]]
* HealingFactor: Her body is nearly immune to physical and light energy attacks since they'll phase right through her, as she can reconstruct herself from any damage taken, however her body won't be able to keep up if taken too much damage.
* HeelFaceTurn: [[spoiler: After Rito rescues her by offering to share his body,]] she's changed from being outright malicious to simply being wildly mischievous. She's grown to actually support the Harem plan, wants Rito and Momo to get together, being actually disappointed when something [[MoodKiller interrupts them]], and is actively doing whatever she can to make everyone, including Yami, happy with him.
* ItAmusedMe: After Mea and Yami both are "led astray" by their time on Earth, she decides to also pay a visit there. She then decides to tease Rito quite a bit, finding it interesting.
* KimonoFanservice: Type B, of the GoingCommando Variety.
* MistressAndServantBoy: She loves to force Rito to do her bidding, and keeps asserting that he's her servant.
** In one of the comedy {{Yonkoma}} strips, she walk into a MaidCafe, is confronted with a bunch of maids calling her "Mistress" and concludes that it's the Best Place Ever.
* MsFanservice: Well, she is a girl that: never wears panties, can change the size of her breasts or tranform her entire body and has no problem in showing her naked ''anything'' to Rito.
* NamesToRunAwayFromReallyFast: Her name is ''Nemesis''.
* NoSenseOfPersonalSpace: Nemisis has zero sense of personal space and seems to enjoy getting uncomfortably close to others. She has also been shown to be something of a CuddleBug as she ends up clinging to Rito whenever she has the chance.
* NoSocialSkills: Her stated reason for remaining in the shadows.
* NotSoDifferent: From Momo, who finds her ''very'' distasteful.
* OhCrap: [[spoiler: When Mea, with the help of Oshizu's PsychicPowers, manages to separate herself and become free from her grasp.]]
* PowerPerversionPotential: Shares this trait with Yami and Mea, but Nemisis literally hits Rito in the face with this by aging herself up and subjecting him to MarshmallowHell. Momo also notes how "convenient" it is.
** She can change her appearance into anything she desires. Another chapter has her transform her body into Yui, Mikan and Lala in order to tease Rito.
* RapunzelHair: Like Yami she has long hair, but hers is black.
* SharingABody: [[spoiler: After Nemesis' battle with Gid nearly killed her, Rito offered his body for her to use as a temporary vessel until she recovered her strength. Much to his chagrin, this allows her to take control of his body to say and do things he normally wouldn't such as being openly perverted and jumping Momo to fondle her.]]
* ShamelessFanserviceGirl: She is undeniably an exhibitionist. Not only does she like to molest Rito and Momo in public, but after [[spoiler: SharingABody with Rito]], especially when she knows she's being watched, she will manifest in a way that makes it look and sound likes she's having full blown sex with Rito, as much as possible.
* SoftspokenSadist: Is very calm in describing... [[BondageIsBad things]] she want to do to Rito.
* SplitPersonalityTakeover: [[spoiler:Nemesis said that Mea was nothing but a split personality Nemesis fabricated to get close to Rito and Yami, and Nemesis pulls off a hijack once Yami's Darkness protocol activates. It's later revealed, however, that Nemesis lied just to push Yami over the edge and that Mea is an actual person. It's just that they fused when they first met as Nemesis was physically unstable and Mea was mentally unstable.]]
* TrademarkFavoriteFood: Mitarashi Dango, which she's seen with every other time she makes an appearance.
* TheVamp: Probably the most sexual character shown so far. She's far more direct than even Momo and is vastly more depraved. [[spoiler:After her HeelFaceTurn she became more a LovableSexManiac]].
* VoiceChangeling: In addition to her shape-shifting abilities, she can also change her voice to sound just like anyone.
* VoluntaryShapeshifting: Nemesis can alter her appearance and reshape her body to look more adult-like and even change her appearance to look exactly like other people. She can fully transform into animals, even those much smaller than herself, such as a crow or a cat. She can also grow a pair of butterfly wings that gives her the ability to fly.
** BreastExpansion[=/=]OvernightAgeUp: Does this to give Rito a taste of MarshmallowHell. She manages to impress Momo with her [[PowerPerversionPotential power]].
* VoiceChangeling: Part of her skill set, as seen first in the chapter 29 of ''Darkness'', where she used Rito's voice to [[EvilIsPetty get Momo into trouble with Mikan]].

->'''Voiced by:''' Creator/TakehitoKoyasu
Lala's bodyguard and the ace of the Devilukean military, Zastin was tasked to retrieve Lala until he was mistakenly swayed by Rito's words on Lala's ArrangedMarriage, citing he truly understands the princess' feelings (though that wasn't what Rito meant). Choosing to stay on Earth to continue watching after Lala, Zastin in the meantime works as an assistant for Rito's father Saibai and is learning how to draw manga himself.
----

* {{Bishonen}}: Saki fell in love with him because of this.
* BunnyEarsLawyer: Much to Gid's chagrin, Zastin becomes quite an accomplished mangaka under Saibai's direction. [[CompressedAdaptation Well, in the manga, at least]].
* CharClone: His role in the last episode(s) of the 1st anime gives off this vibe. The fact that his [[Creator/TakehitoKoyasu voice actor]] has voiced [[Anime/MobileSuitGundamWing other]] [[Anime/MobileSuitGundamSeed Char]] [[Anime/MobileSuitGundamSeedDestiny clones]] in the past is already saying something.
* TheChewToy: Literally -- the first time Rito meets him, a stray dog starts gnawing the bone-like "armor" on Zastin's leg. The dog shows up, again chewing his armor, at least once more in the series.
* DemotedToExtra: He starts getting less and less screen time in the anime, and doesn't play much of a role by the time ''Darkness'' rolls around.
* {{Expy}}: To Creed Diskenth of ''Manga/BlackCat'', at least in appearance and powers, except he's more of a bumbling but amiable soldier.
** Taking the anime and his voice actor into account, he can arguably be one to [[Anime/MobileSuitGundamWing Zechs Merquise]] or [[Anime/MobileSuitGundamSeed Mu La Flaga]].
* FauxActionGuy: He's supposedly a very competent fighter, but he either arrives late to the party or gets knocked out one way or another at the beginning of the fights.
* IronButtMonkey: Military training in Deviluke sure prepared his body for a ton of harm hurled his way.
* LaserBlade: Zastin always carries a big green energy sword.
* MasterSwordsman: His official occupation.
* NoSenseOfDirection: Justified, since [[FishOutOfWater Earth is an unfamiliar environment to him in the beginning]]. Unfortunately, he gets hammered with this in subsequent reappearances that it mostly derails him.
* ShouldersOfDoom: That he wears ''[[TwentyFourHourArmor contsantly]]'', regardless of how much this makes him stick out like a sore thumb on Earth.
* ThoseTwoGuys: Occasionally seen with his aides, Maul and Smutts.

A childhood friend of Lala, Ren hails from the planet Memorze (a planet shown by one of Lala's flashbacks as [[http://www.mangafox.com/manga/to_love_ru_darkness/v02/c010/31.html an Arabian-styled world]]). When they were children, Lala absentmindedly promised him to marry him should he become manly. Taking it for face value, upon arrival on Earth, Ren arrives to prove that he's manlier than Rito. Unfortunately, his pursuit leads to an unexpected circumstance with "Run", his alter-ego -- and a girl both in body and personality -- triggered by a sneeze. In direct contrast to Ren, Run is infatuated with Rito, leading her to become an idol in hopes of gaining Rito's attention.
----
* AccidentalKiss: Ren with Rito. The surprising thing here is that this incident is what caused Run to fall for Rito.
* ADayInTheLimelight: Their one standout chapter in ''Darkness'' is when [[spoiler:Ren and Run split into two separate beings]].
* BigEater: Run, in the anime only.
* ButtMonkey: Both of them.
* DemotedToExtra:
** Ren. His early role as Rito's rival is put aside in favor of Run. In ''Darkness'', [[spoiler: after that Ren and Run have literally split into two separate individuals]], he rarely appears.
** That said, Run doesn't get to spend much time with Rito either, mostly because of her work as an idol, but also due to the sheer amount of girls around him.
* {{Expy}}: Of Ran from ''Manga/UruseiYatsura'' (their names are almost the same even), minus the BitchInSheepsClothing aspect of her character. Like Ran with Lum, Run was Lala's childhood friend who went through a lot of slapstick abuse and was forced to dress up like a girl as Ren. At least Ren/Run didn't get spanked like Ran did, though.
* GenderBender: Memorzeans can change gender via a particular stimulus. In his/her case, it's a sneeze, though it's supposedly only that easy when on Earth.
* HalfIdenticalTwins: [[spoiler: They become this after their split.]]
* HopelessSuitor: Ren no matter what he does can't change Lala's mind about who she likes. Similarly, Run also has problems trying to seduce Rito.
* IdiotHair: Both of them.
* IdolSinger: Run becomes one around midway through the story.
* IWantToBeARealMan: Ren strives to be manly after Lala absentmindedly agreed to marry him if he did back when they were children.
* JerkWithAHeartOfGold: Ren.
* LiteralSplitPersonality: [[spoiler:As of ''Darkness'', Ren and Run have literally split into two separate individuals as a result of achieving a metamorphosis simply described as "reaching adulthood". Naturally, both have something to be happy about.]]
* PepperSneeze: In case (s)he needs to switch genders on the fly.
* SingleTargetSexuality: Run to Rito and Ren to Lala.
* StalkerWithACrush: Run has some tendencies in this direction, especially in episode 16, which focuses almost entirely on her stalking Rito. Ren initially for Lala; however, with the progress of the series, he seems to have given up.
* UnluckyChildhoodFriend: Ren towards Lala, [[spoiler:though with he and Ren splitting into individual bodies, he may have a chance with Lala again]].
* IWantMyBelovedToBeHappy: In "Darkness", Ren doesn't seem to try to impress Lala or try to compete against Rito anymore, so it's possible that he has accepted him as Lala's lover, although Ren still shows his love for her.
* YouGottaHaveBlueHair: Run has sea-green hair.

Dr. Ryouko provides medical care to other extraterrestrials on Earth, but isn't above providing mysterious concoctions to her students.
----
* AbsoluteCleavage: Mikado often wears a pink top that slightly shows the top of her breasts.
* AdaptationExpansion: She appears a lot more often in the first TV series than she does in the manga.
* ADayInTheLimelight: For ''Darkness'', chapters 65 and 66 are standouts for Mikado as she tries to help Rito correct what she dubbed as his "Cataplectic Indecency Syndrome" disease. After being subjected to Rito's "talent" as an AccidentalPervert, Mikado claim that she doesn't want to defy an act of god anymore, and that he's better off just letting his disease help women fall in love with him.
* CoolBigSis: One of the few adult females in the series, who often gives advice and information to the younger characters.
* DarkAndTroubledPast: Was part of an operation to overthrow Gid Deviluke at one point in her life. These days, she keeps a low profile as a nurse on Earth.
* HaremNanny: Is pretty much the only somewhat sane female character next to Mikan. She does have her moments though...and then ''Darkness'' 66 happened.
* TheImmodestOrgasm: [[spoiler:Rito gives it to her so good, she's convinced that his AccidentalPervert moments are his natural '''talent'''.]]
* LaserGuidedKarma: After using Tearju as a ButtMonkey for the entirety of chapter 66, Rito's treatment regiment has him target ''her'' for his AccidentalPervert mishap. She's ''overjoyed.''
* MsFanservice: Next to Tearju, she's got the biggest breasts in the series easily. Only difference is that Mikado [[AbsoluteCleavage has no problem showing them off]].
* PointedEars: The only visible sign of her alien heritage, though normally concealed by her hair.
* SchoolNurse: She is the school doctor of Sainan High
** HospitalHottie: Outside school, she provides medical care to other extraterrestrials on Earth.
* TheTease: Has no problem teasing Rito from time to time about his particular "issues" over women.

* AscendedExtra: Kyouko was born as fictonial character of her ShowWithinAShow. After, she appears as real character and became Run's best friend. In "Darkness" she is also promoted to new potential harem member of Rito.
* BigBad: Her "role" during the Trouble Game arc. Well, was not the real Kyouko, but a an artificial character created by Lala sisters.
* CatchPhrase: As "Magical Kyouko"...
-->"Whatever the problem is, I'll solve it by [[KillItWithFire burning it]]!"
* ClarkKenting: Inverted with "Magical Kyouko". As Kyouko reveals to Run in an episode where Run costars as a MK villain, she actually DOES have [[PlayingWithFire pyrokinesis]] in real life thanks to her [[HalfHumanHybrid alien heritage]]. "Magical Kyouko" was created by her idol producer as a way for her to use her powers constructively without [[BrokenMasquerade revealing them]], as anyone not involved in the show would believe it to be a special effect.

* MagicalGirl: What her show is all about.
* {{Meganekko}}: Her look as student.
* PlayingWithFire: Kyouko possesses the ability of fire manipulation, the power to create and control fire with her mind and burn whatever she may desire. She usually passes this off as magic tricks and special effects on her show during her acting role as Magical Kyōko TV series, or to defend herself from perverts like the Principal. Kyouko is also able to create constructs made of fire, such as flame lettering in the air.
* ShipperOnDeck: Kyouko knows about Run's feelings towards Rito and wishes the best of luck in getting him.
** PromotedToLoveInterest: Although in ''Darkness'' she fall for Rito herself after being subjected to the "[[BridalCarry Princess Carry]]".
* ShowWithinAShow: The star of "Magical Kyouko", an obvious parody of the MagicalGirl genre -- where else can you find a transformation that involves the girl going to the toilets to change, or troubleshooting by burning?

!!Celine
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/celine_toloveru.jpg]]
->'''Voiced by:''' Creator/RyokaYuzuki
Lala's gift to Rito for his sixteenth birthday, Celine was a giant, sentient sunflower kept in his backyard. Like the rest of his plants, Rito makes sure Celine is cared for, even referring to it as his family. After Celine contracts a disease, causing it to dry up and germinate, out pops an infant Celine from the seed. Looking like a human child (except with a noticeable flower on her head), Celine lives with in the Yuuki household and occasionally calls Rito "Mama".
----
* BlushSticker
* CheerfulChild: She loves people, coke, and well anything, being a toddler who's curious about the world.
* ChildrenAreInnocent: She might as well be the poster child for this trope. She is so well behaved that Rito can take her ''anywhere'' without fear of her causing an incident. He's taken her to his high-school without incident, numerous times. She's been in Lala's laboratory, where even Rito himself is not safe, without any issue, as long as she's kept occupied, and has at least minimal supervision. The only time(s) she's gotten in trouble are when she's drunk on soda, or somebody left her unattended in front of a tempting portal. Further, nobody takes issue with her sucking on ample exposed breasts because she's a toddler, and that's what they do.
* DrunkOnMilk: Like [[Manga/AhMyGoddess Belldandy]], Celine can't handle cola.
* GoodParents: Celine is truly blessed to have these. Rito and Mikan are at the top of the list, of course, but everybody in Rito's harem and Saki has had a turn at looking after her, and they are all willing to bend over backwards to make her happy, if they can.
* HappilyAdopted: For all intents and purposes. Despite not being Rito's child, by blood, she recognizes him as "papa."(Which is well deserved.) Unfortunately, despite Lala being the one who actually filled out the paperwork, and brought her to the Yukki household, Celine recognizes ''Mikan'' as "mama." Chapter 36.5 of Darkness makes this explicit on the final page.
* {{Human Alien|s}}
* IsThatCuteKidYours: Frequently mistaken for being Rito's daughter.
* LovePotion: When she is drunk ([[DrunkOnMilk with cola]]) the flower on her head can spray a pollen that temporarily causes anyone who inhales it to fall in love with Rito, man, woman or animal. It was theorized to be a side-effect from Celine's affection for her "Mama".
** In one of the extra chapters from ''Darkness'', we get to see how Celine's pollen works from a first-person perspective: It strongly induces sexual arousal in response to highly specific set of stimuli, i.e. anything related with Rito. Things like his voice, visage, presence and particularly his touch become ''huge'' turn-ons to the person infected with the pollen. Interestingly, it turns out that if said person already has an interest in Rito (eg. Mikan, Yami), they behave distinctly from the rest and are better able to control themselves, probably because they have an easier time differentiating their own feelings from the induced ones.
* MarshmallowHell: Inverted. One of her favorite things to do is latch on an ample bosom and start sucking. Not because she's breastfeeding, but because she's merely curious about the experience. Since she's practically a toddler, nobody bothers to correct her on this. The one who came closest, Lala, just directs her to another target, ''Riko.'' Amusingly, Lala's also the one who innocently gave her the idea by sharing a children's picture book with her that includes breast-feeding.
* OvernightAgeUp: In one chapter, 36.5 of Darkness, she grew to resemble a preteen girl and then reverted back to being an infant.
* PlantAliens: Even as a plant, Celine behaves like a human -- sweating when hot, wearing an oversized scarf when cold, and eating a giant bowl of ramen when hungry. Of course, she subverts it later and becomes a {{Human Alien|s}}.
* TrademarkFavoriteFood: Ramen.
* TokenMiniMoe: Of the entire cast, discounting the preteen Mikan.
* VerbalTic: "Mau!"
----

!! Black
He is a hitman who knows Golden Darkness in the past, as he is the one who set her free from the Eden organization.

* AntiHero
* {{Expy}}: Of Train Heartnet, the main character of ''Manga/BlackCat''. Also his name, Black represents Train's nickname as an assassin "Black Cat". Ans he is also friends with Eve, the character whom Yami resembles in both apearance and abilities.
* EnergyWeapon: Black's primary weapon is a gun he carries around for the use of his skilled marksmanship. This gun that can manipulate psychic energy and fire the energy in the form of bullets.
* TheGunslinger: Black is a master gunman, using his guns to accurately shoot and kill his opponents.
* HeroOfAnotherStory: He was the one who destroyed the Eden organization that created Yami, setting her free.
* TheStoic: He seems to be very moody and hardly shows any emotions.
* TallDarkAndHandsome

!!Prof. Tearju Lunatique
[[quoteright:350:http://static.tvtropes.org/pmwiki/pub/images/tearju_toloveru.jpg]]
->'''Voiced by:''' Creator/MisatoFukuen
->'''Sainan High School:''' Substitute Teacher
A motherly figure to Yami who has taken a job as a Sainan High School substitute teacher in order to continue watching over her. As a foremost genius in the field of biotechnology, Tearju was once a part of a scientific team that [[spoiler:created Yami and also provided her biological makeup; making her technically the latter's mother. She left the group, however, due to disagreements over treating Yami as a LivingWeapon against the Deviluke family, and vanishes without a trace. In reality, she was being hunted down by her former clients until she was found by her university classmate, Dr. Mikado, who convinces her to come to Earth in hopes to help her reconcile with her "daughter"]].
----
* AdoptivePeerParent: Of a surrogate sorts towards [[spoiler:Yami]].
* {{Adorkable}}
* BlindWithoutEm: So blind she can faceplant into Rito's crotch and be more concerned with her missing glasses.
* ButtMonkey: As Rito shares his trait of being prone to bad luck, Mikado forces her to be her guinea pig for testing Rito's ''skill''.
* ChristmasCake: Downplayed. Mikado teases her about how she's not qualified to give romantic advice because her childhood obsession with biology single-handedly strangled every potential relationship Mikado aimed her way. Tearju tries to fire back about Mikado's similar status, but to no avail.
* CuteClumsyGirl: She can be very shy and clumsy, both physically and socially, and can sometimes end up in awkward moments. She can be every bit as klutzy as Rito, even inverting his usual face-planting paradigm.
* {{Expy}}: Of the same-named character in ''Manga/BlackCat''. [[spoiler:''Darkness'' leans her towards being an AlternateUniverse version, with the link between the two Tearjus being the character "Eve" (which happens to be Yami's true name)]].
* GreenEyes: Has green eyes.
* HairOfGoldHeartOfGold: She has very blonde hair and is one of the nicest characters in the entire cast.
* HairIntakes: Her hair has a pair of what look like cat ears.
* HotScientist: Tearju studied Biotechnology and she was part of an organization that would create Eve [[spoiler: (later named Yami)]].
* HotTeacher: [[spoiler: She is currently a teacher at Sainan High. In the first day she is immediately harassed by boys in the class, such as Saruyama, who asks her various questions, such as if she is single]].
* HumanAlien: Out of all the alien characters, she appears to be more human than all the others.
* InUniverseNickname: "Tear", [[spoiler:even by Yami]].
* TheImmodestOrgasm: Subverted. It's pretty clear that in the extra chapter of volume 7 (''It Feels'') she reaches orgasm, but when she actually does climax she covers the mouth with her hand and doesn't make a sound.
* {{Meganekko}}: Always wears glassess.
* MissingMom: [[spoiler: To Yami. Tearju raised her like a little sister.]]
* MotherlyScientist: She was part of an organization that would create Eve [[spoiler: (later named Yami)]]. Tearju raised her like a daughter/little sister, and would really, ''really'' like to resume that relationship; unfortunately, she's not talented at it, and more often comes across like [[MeddlingParents a Meddling Parent]].
* MsFanservice: She is one of the most physically curvaceous characters in the series, possibly only second to Mikado.
* NiceGirl: She is very kind to those around her.
* OhCrap: Has several, but the most telling is seeing (and recognizing) Yami's "Darkness" transformation.
* RapunzelHair: Tearju has long blond hair.
* ReluctantFanserviceGirl: Since her first appearance where she and Rito end up naked thanks to Lala's teleporter device. Special mention when Mikado uses her to test Rito's "skill."

[[folder: Alien Antagonists]]

!!Gid Lucion Deviluke:
See Deviluke Family.

!! Ghi Bree:
One of Lala's other suitors, and the first that Rito has to defend her from.
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/bree_ghi_0.jpg]]

* AbhorrentAdmirer: He is physically and morally repulsive.
* HaremSeeker: Of the "traveling salesman" variety, at least in the anime. He has a history of marrying females of various species, and then running away once he sires offspring.
* {{Jerkass}}: He blackmailed Rito into giving up Lala when taking Haruna hostage, for which Rito describes him being the worst.
* LaserGuidedKarma: In the manga, Lala flushes him down what looks like a toilet. In the anime, the wives and children he abandoned come looking for him instead. YMMV on which is worse.
* ParentalAbandonment: In the anime, he abandons his wives to find new ones once he produces offspring.
* RapeIsASpecialKindOfEvil: Implied. He certainly is not averse to drugging/ paralyzing females, ''deliberately'' stripping their clothes off, against their will, and molesting them. Fortunately, Rito came to Lala and Haruna's aid before we found out if he would go all the way.
* ThisCannotBe: He was utterly stunned that Rito would actually attack him.
* VoluntaryShapeshifting: He can make himself ''look'' like a roid-raging demon, but he lacks the physical strength to match. [[TheSoCalledCoward Rito]] did not hesitate to call his bluff. [[http://static.tvtropes.org/pmwiki/pub/images/ghii3.jpg This]] is his real form.

!! Lacospo:
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/lacospo.jpg]]
The second of Lala's other suitors. He is the one who hired Yami to go after Rito.

* AbhorrentAdmirer: He is every bit as unpleasant as Ghi Bree, and then some.
* BadBoss: Yami made explicitly clear that in order for her to succeed in her contract, the information on her target must be accurate. When she found out he outright ''lied'' about Rito's character, and confronted him on it, he tried to have her SwallowedWhole.
* ClothingDamage: He brings with him a giant frog whose very existence is dedicated to this purpose, before swallowing people whole.
* CoolCrown: He wears a rather nice looking crown.
* TheEvilPrince: Lacospo is a prince from the planet Gaama. Like most of Lala's fiancé candidates, he claims to have deep love interests in her but also like the others, he only cares about being the next successor to Deviluke.
* {{Expy}}: Lacospo has a slight resemblence to a ''Manga/DragonBall'' character, Emperor Pilaf. Both are small evil guy, have odd colored skin, pointy ears and wear a smilar outfit.
* ILied: He outright lies to Yami about Rito's character, and when she confronts him on it, wondering what else he's lying about (like her reward) he tries to kill her by having his pet clothes-dissolving frog swallow her whole.
* {{Jerkass}}: He hired Golden Darkness and Ranjula to assassinate Rito.
* LittleBitBeastly: He has some frog or toad features.
* ScrewTheRulesIHaveConnections: He's apparently the heir apparent for becoming king of his race.
* SmallRoleBigImpact: He only has one episode in the anime, and even less of a presence in the manga, only appearing in a cameo or two, but without him Yami, and later Mea and Nemesis would never have come to Earth.
* SunkCostFallacy: Sends an assassin after Rito to claim Lala for himself. When the assassin in question finds out he was lying, and voids the contract, he sends another assassin after the first, to recover his reputation, and take Lala. When that fails, he sends yet another assassin, and threatens the entire Deviluke family, to take Lala... Until Nana puts him in his place with a Giant Cobra, his race's natural enemy. As of this update, he has yet to return, although at least four bounty hunters, not hired by Nemesis, show up gunning for Yami, and scared off by Mea.

!! Ranjula:
One of the other assassins hired by Laposcopo to try and assassinate Rito.

* EvilGloating: Instead of killing Rito when he had the chance, he stopped to gloat at Yami's apparent helplessness instead. [[spoiler: It allowed Rito to come to Yami's aid and defeat him.]]
* EvilLaughter: When she had Rito and Yami trapped in her webs.
* UnknownRival: To Yami. Yami didn't even know who he was, but one of the reasons Ranjula accepted the contract on Rito, is that he could go after Yami in the process.

!! Mea:
See Living Weapons.

!! Nemesis:
See Living Weapons.

!! Azenda The Tyrant.
[[quoteright:308:http://static.tvtropes.org/pmwiki/pub/images/azenda.jpg]]
A rival assassin from Yami's guild. Formerly the number one assassin in the galaxy before Yami took the title.

* BlondesAreEvil: She's got blonde hair and she's a truly rotten person.
* DarkSkinnedBlonde: Very dark skin, and blonde hair.
* DirtyCoward: Attacks Yami from ambush and then hides behind Mikan to prevent counter attacks.
* EvilGloating: She's not just about killing Yami, she's out to humiliate her too. This would cost her the victory, twice.
* MindOverMatter: She is psychokinetic.
* MoreThanMindControl: Does this to Mikan to prevent Yami from fighting back.
* MuggingTheMonster: Threatened Momo to try to keep her from interfering with Yami's humiliation and execution, using Mikan as a puppet. She quickly realized why that is a bad idea.
* PeoplePuppets: Her preferred method of combat, when on Earth, since humans have little to no resistance to her abilities.
* RapeByProxy: Uses a mind-controlled Mikan to try to rape Yami before killing her.
* TheResenter: Loathes Yami with a passion because Yami dared to be better than her in combat, and in the assassin business.
* {{Revenge}}: Wants to kill Yami both to reclaim her spot as number one assassin in the galaxy and to avenge her (non-lethal) loss in combat.
* SmugSuper: Thinks and acts like she's vastly superior to everyone in the cast. Momo wound up only too happy to show her how wrong she is. [[spoiler: And during their rematch later in Darkness, Yami not only curbstomps her, but makes it ''very'' clear that if she dares go after Mikan again, for any reason, her life is forfeit.]]
* {{Stripperific}}: Her outfit leaves very little to the imagination.
* VillainsWantMercy: She's quick to beg forgiveness and plead for her life when Momo has her cornered, and unable to move. [[GoodIsNotSoft Momo declines, though does not actually kill her.]]
* VirtueIsWeakness: She outright condemns Yami for daring to make friends on Earth, especially Mikan... Until Momo comes to Yami's rescue.
* WhipItGood: She also attacks with a whip when she's not using people puppets or psychokinesis.
