Rito Yuuki is a [[OrdinaryHighSchoolStudent hapless high school teenager]] who's hopelessly in love with the shy, gentle Haruna Sairenji, but just can't work up the nerve to confess his feelings. One night while taking a bath, however, a gorgeous (and naked!) alien princess named Lala Satalin Deviluke crash-lands into his bathtub, and things just spiral out of control from there...

Written by Hasemi Saki and illustrated by Kentaro Yabuki of ''Manga/BlackCat'' fame, ''To-Love-Ru'' is, well... you probably haven't ''seen'' {{fanservice}} until you've seen or read at least a minimal amount of this series. The manga debuted in April 2006, while an AnimatedAdaptation premiered two years later and ran for 26 episodes. Six {{OVA}}s have been released, and a second TV series, ''Motto To LOVE-Ru'', began airing in June 2010.

Unfortunately, due to Yabuki's messy divorce and subsequent custody battle over his three year-old daughter (see CreatorBreakdown below), the manga was officially and [[CutShort very abruptly]] cancelled in the Japanese ShounenJump magazine. He has since gotten better, and did an eight-month stint illustrating [[MayoiNekoOverrun another manga series]] (which has cameo appearances from To-Love-Ru characters and takes place in the same city).

A SpinOff[=/=]sequel manga titled ''To-Love-Ru Darkness'', launched in October 2010, reunites the author and artist. It is centered around Momo's plan to share Rito with the others whose happiness depends on him, and an unknown antagonist who controls several assassins similar to Yami, as well as Yami's DarkAndTroubledPast. While characters of the original manga return, ''Darkness'' [[AscendedExtra promotes]] both Yami and Momo to main characters and [[DemotedToExtra significantly downplays]] the original protagonists. The fanservice in ''Darkness'' has been amped UpToEleven, to the point where Rito has "AccidentalPervert'ed" his way through at least ''five'' heavy make-out sessions with ''entirely different women''. An anime adaptation premiered in October 2012.

Note that "To-Love-Ru" is a [[BilingualBonus multilingual]] {{pun}} on the word "trouble"; in Japanese, these are pronounced identically (''toraburu'').

----
!!To Love-Ru and Motto To Love-Ru provide examples of:

* AboveTheInfluence: While painful for him, Rito will often resist the advances the many girls push on him.
* AccidentalMarriage: Groping an alien princess breasts is grounds for [[DisproportionateRetribution engagement]]. In the manga, it's more of his speech about freedom of choice that causes her to fall in love with him, and she decides he's the only wedding candidate worthy of her.
* AccidentalKiss: Rito and Ren.
* AccidentalPervert: Played Straight, Exaggerated, Inverted, Subverted, ''Double'' Subverted, Deconstructed, Reconstructed, Enforced, Lampshaded, Invoked and Played for both Laughs and Drama.
* ACupAngst: Nana is not well developed, much to her frustration.
* AdaptationDyeJob: Devilukean tails are actually (very dark) red. The anime always shows them as pitch black, instead.
* AdaptationExpansion: ''Motto'', as part of the improvements, sometimes added scenes, usually only very small, that generally added connectivity or depth. For example, in Risa's DayInTheLimeLight Episode, the manga ends with Rito receiving Risa's text. In ''Motto'', there is a following scene where Risa stares at her phone longingly, implying she was serious about her offer.
* AllThereInTheManual: ''Motto To LOVE-Ru''; while it doesn't expect you to know certain things, doesn't exactly explain them either. For example, if you want to know why Celine has a human form? You can only find the full explanation in the manga and an OVA episode. There are other things too, but most are minor.
* AlwaysInClassOne
* AManIsNotAVirgin: Averted. While it's safe to say Rito probably has thought about having sex with one of the girls in his harem, his problems with girls in general see to it that he will stay a virgin for quite some time.
* ArtEvolution: There's a noticeably different art style between the first season, the OVA, and ''Motto To LOVE-Ru''. The OVA enlarges nearly everyone's eyes and headed into UncannyValley in the process, while ''Motto'' has a new directing staff. The characters don't look ''bad'', but they do look quite different from the original manga now.
* ArtificialRiverbank: Where Rito takes Lala in an early effort to break up with her. [[spoiler:She falls for him instead]].
* AttemptedRape: Happens to Rito several times.
** Rito, tied up to a bed as an [[TheAmazon Amazon]] slowly reaches lower, while talking about how he will be her husband, before Lala intervenes. Make of ''that'' what you will.
** Implied with one of the early villains and his use of naughty tentacles.
* AttractiveBentGender: [[strike:Rito]] "Riko" gives the other {{fanservice}}-females a run for their money.
* AwesomeYetImpractical: Yami's barehanded fighting is quite flashy, as demonstrated when they go to Planet Mistletoe.
* BadassAdorable: Yami, for certain. Lala also qualifies to a smaller extent.
* BadassNormal: Rito Yuuki, ActionSurvivor OrdinaryHighSchoolStudent UnluckyEverydude from a series full of MegatonPunch and StuffBlowingUp, also [[GrievousHarmWithABody living human weapon]]. Guaranteed [[JokerImmunity to survive]] any [[AccidentalPervert any accident]] because he's [[strike:MadeOfIron]] [[NighInvulnerable composed of Adamantium-level bones, Wolverine-level-healing muscles and superelastic skin compiled with fireproof hair]] being merely human.
* BarbieDollAnatomy: And thank goodness; considering just how ''often'' the manga's frames are placed at crotch level (even for Mikan and Yami) during {{Furo Scene}}s, TLR would've been unavailable outside the R-18 shelf without this trope.
** The serialized version used this trope in conjunction with nipples, but it's averted in the volumes, where nipples are clearly shown.
* BeachEpisode: Chapter 113 is adapted into the third OVA, and is so overloaded with {{fanservice}} it seemingly forgets to have a plot or dialog and just features the girls posing in swimsuits to ambient music for several minutes at a time. And then there's the comparison of tanlines near the end...
* BerserkButton:
** Nana with flat-chested comments.
** Lala with suitors fighting over her.
** Ren being called unmanly.
** Yami, with any form of ecchi.
** Rito, when someone close to him seriously threatened. {{Beware|TheNiceOnes}}. [[http://static.tvtropes.org/pmwiki/pub/images/toloveru06_25_8156.jpg OH SHI-]]
* BewareTheNiceOnes:
** Lala is quite obvious, but so is Rito, just ask Ghi Bree.
** Get Momo mad and you could very well be in trouble. Even Yami was impressed with her killing intent.
* BigBrotherAttraction: Evidence has piled up that Mikan has a deep-seated crush for her brother Rito. [[spoiler:Made ''more'' obvious in the second OVA with a jealous Mikan wondering what it would be like if they [[NotBloodSiblings weren't related]] right after joking about marriage]].
** Her reaction for being questioned by Nana about love interest.
** The infamous Chapter 157, in which:
*** Mikan's accused of turning down her male classmates' affection because of, as her friends put it, her "awesome brother". Cue SuspiciouslySpecificDenial to the accusation.
*** She has an unusually jealous reaction to Momo hanging onto and teasing Rito.
*** "T-that's not marshmallow!"...You'll need to read the chapter to understand the context of that.
*** She questions herself, thinking "What exactly am I trying to do here...?" In the end, it seems she's rather content to be the beloved little sister.
** She plays with this trope a bit when she tells Rito they are not related by blood just to see his reaction, only to admit she's just kidding afterwards. Later, Celine [[LoveIsInTheAir works her usual magic]] on Mikan, which results in some sexual tension.
* BigDamnHeroes: Averted hilariously in episode 4. Zastin busts into a classroom with some giant octopus/squid, and gets thwarted by them each time he tries to save Lala, Rito and Haruna.
* {{Bishonen}}: Yuu, Rito, Ren and Zastin, Lala's bodyguard. Note: Despite being straight bishonen, Rito [[InvertedTrope isn't]] [[ChickMagnet attractive]] because of his [[BiShonen coolness]], it's his [[DoggedNiceGuy kindness]] that become the magnet. On the other hand, Ren is [[IncrediblyLamePun straight]] example, being [[JerkWithAHeartOfGold somewhat rude]]. And Yuu is brand-new of ChivalrousPervert-HandsomeLech hybrid.
* BumblingDad: Saibai Yuuki, Rito's father
* ButtMonkey: Zastin; quite explicitly in the manga, while he's merely an idiot in the anime.
** There's also the perverted principal who's so perverted he makes Rito look like Jesus Christ in comparison!
*** Lastly, Rito himself. Many of his perverted accidents end up with a certain yellow haired assassin hot on his trail.
* BreatherEpisode: Episode 14's a refreshingly mundane, but heartwarming look at what Rito and Haruna's relationship could be like without all the extraterrestrial insanity. A wise directorial choice, considering for the '''rest''' of the series, this blessed normality '''never''' returns again.
* {{Cameo}}: In return for visiting [[MayoiNekoOverrun Stray]], Peke gets some peculiar manga to read.
* CanNotSpitItOut: Rito's repeated attempts to confess to Haruna.
** And even when he manages to, Lala gets in the way.
** Averted for [[spoiler:Rito towards Lala though. As soon as he is sure of his feelings, he takes her aside and tells her he loves her. He then proceeds to, at her insistence, attempt to confess to Haruna, only to be interrupted by her running away and getting replaced by half the female cast just in time for him to say the three magic words.]] This being the end of the last chapter, much rage ensued. The prologue chapter of ''Darkness'' explains he told the girls that he was talking to/about the pool.
** One has to wonder just ''how much'' Yui can possibly hold in every time she's alone with Rito.
* CanonDiscontinuity: It's stated in the first chapter that except for matters dealing with women, Rito is aggressive and strong. Unfortunately, he's almost always dealing with women, so this attribute usually only surfaces when a new haremette shows up that needs to be impressed by his [[HotBlooded hot bloodedness]], or when one of his existing haremettes is in trouble.
* CanonImmigrant: Plots from multiple H-doujinshi have been partially incorporated into the series.
* CaughtTheHeartOnHisSleeve: Episode three
* CaughtWithYourPantsDown: Momo gets caught by Nana while playing with [[FantasticArousal her tail]]. Although she kicks Nana out of the room before she can realize what Momo was doing.
* CensorSteam: Used quite a bit in both the anime and manga. Streams of light coming through a window is rather creatively used for this. CensorSteam and GodivaHair only appear in the serialized version of magazines and episodes. The collected volumes and [=DVDs=] of the manga and anime subverts this and are "uncensored", featuring unobstructed views of the female characters' chests.
* CharacterDevelopment: Subtle, but definitely there.
** Rito goes from boy with crush on a girl he can't even think about in a bikini without a meltdown to a boy in love with two girls and only freaks out if they're naked.
** Lala goes from a bratty princess who only pretended to like Rito to stay away from her suitors to a kind, unselfish and mature(ish) young woman very much in love with Rito ''and'' her best-friend/love-rival, and willing to risk her life to protect ''both'' of them.
** Haruna goes from painfully shy and self-conscious to... less shy and self-conscious.
** Yui drastically mellows out over to course of the series, going from "how indecent" to joking and laughing about Rito's AccidentalPervert moments.
** Golden Darkness arguably received the most character development when it comes to direction, outranking Rito/Yui. She went from cold-blooded assassin to [[spoiler:nearly being killed by an assassin because BrainwashedAndCrazy Mikan was in the way and she refused to harm her, smiling constantly around Rito and Mikan, and even being nicer to Rito]].
* TheChewToy:
** Poor, poor Rito.
** Also, Zastin, quite frequently.
* ChickMagnet: Rito, obviously. Curiously, it seems Mikan's the {{genderflip}}ped version, constantly asked out by boys her age, but always rejecting them. Seems to run in the family. Besides, [[JustifiedTrope she's so cute]]. Rito's status is also [[LampshadeHanging Lampshaded]] rather often, mostly (though not always) by Mikan, who calls him a Playboy, or notes just how many girls surround him. Nana also calls him playboy, and we all know Momo's thoughts on the matter.
* ChuckCunninghamSyndrome[=/=]OutOfFocus:
** Ren hits this ''so'' hard. Sure, we know where he is, but he doesn't appear all that often. Or at all in the last 50 odd chapters. In ''Motto'' he made two appearances over all. Amusingly, this is a case of a character being made OutOfFocus in favor of ''himself'', sort of. Ren and his rivalry for Lala's affections were eventually phased out, and while the humorously embarrassing situations involving him randomly physically and mentally changing into the much more fanservice-bait girl Run became less and less common, Run herself began to appear more and more often on her own with no mention or Ren.
** Characters will rapidly come in and out of focus throughout the story. Barring Ren, Haruna is probably the most affected, as she becomes less prominent in the last fifty or so chapters, and Yui takes up her slack. This is because of [[RealLifeWritesThePlot real life issues]].
** Zastin and his gang.
* ClothingDamage: Metric tons of it, even ''without'' a giant alien frog which literally has no purpose but to melt people's clothes off.
* ClingyJealousGirl:
** Mostly averted: only one or two girls show any sign of jealousy (Run and/or Yui), with the latter debatable. Hell, Lala seems to enjoy it when he [[ShipTease spends time with the other girls]].
** What is interesting is that Run and Yui only display one characteristic; Run is clingy, but doesn't really get jealous, while Yui gets jealous but can hardly be called clingy.
** Rito showed signs of this, particularly early on. He hated it when Ren or other guys got close to Haruna and, to a much lesser extent, Lala.
* ComicbookTime: {{Lampshaded}}
* CompulsorySchoolAge:
** Played straight with Oshizu, but subverted with Nana and Momo. Despite looking around Mikan's age, there's no mention of them going to school. While it isn't outright stated, it's subtly shown they mainly hang out at the Yuuki residence all day.
** Also, Yami, who spends all day hanging around Rito's school reading books.
* ConspicuousCG: The octopus/squid/shrimp/lamprey ingredients in Lala's [[HammerSpace ingredients box]].
* ControlFreak: Yui, though she mellows out quite a bit.
* CosplayOtakuGirl: Mio, one of [[ThoseTwoGuys those two girls]].
* CousinOliver: [[spoiler:Celine, in her little child form.]]
* CrossdressingVoices:
** 16 YEAR OLD Rito is played by Creator/AkenoWatanabe. Yes, that Akeno, who played [[LightNovel/BludgeoningAngelDokuroChan Zakuro]]. Yes, the Zakuro with the high pitched Creator/YuriShiratori-esque voice.
** Fuyuka Oura as Ren/Run, both male and female.
* CrossOver‎:
** An Assist-a-roid from ''LightNovel/AsobiNiIkuYo'' pops up.
** Several ''To Luv Ru'' characters have cameoed in ''LightNovel/MayoiNekoOverrun''.
* CryCute:
** The human form of [[spoiler:Peke]] apparently.
** Also Yui and Run in child form.
* CultureClash: There is a very subtle one between Devilukes and Humans, particularly Lala; she doesn't use honorifics, has [[ShamelessFanserviceGirl no nudity taboo]] which she claims is due to her upbringing, doesn't mind the idea of Rito having multiple lovers as it's considered normal for royalty to have a harem, her people are essentially conquerors and she herself doesn't mind fighting either. Momo and Nana are generally better at fitting in, so it's hard to say what are typical behaviours for a member of the Deviluke race and what are just Lala's quirks.
* CuteBruiser: Given that Yami is, for all intents and purposes, the [[{{Expy}} exact same person]] as [[Manga/BlackCat Eve]], it should come as no surprise she's tiny, adorable, and can kick your ass.
* CuteLittleFang: Nana.
* CutShort: See CreatorBreakdown above, but actually a variation. Unlike most {{Cut Short}}s, this one ended abruptly due to the artist's ManipulativeBastard wife's influence, not the magazine publisher's.
** It was {{Uncanceled}} in the form of ''Darkness'' after the ManipulativeBastard was taken out of the way.
* DemotedToExtra:
** Going to watch the anime? Hope Mikan isn't your favorite character, or you'll be disappointed at how she makes very few appearances after the first 3 episodes or so. Particularly {{egregious}} since most other characters get [[AscendedExtra the opposite treatment]] if anything.
** Thankfully for Mikan fans, the {{OVA}}s and second anime keep her around the whole time and give her fanservice (Though her and Yami are the only ones without shown nipples, sadly. Despite having them in both manga).
* DoubleStandard:
** Yami makes her hatred of "ecchi" people clear by hitting or slashing at men or boys (especially Rito) who ''accidentally'' get a look under her skirt or touch her breasts - or even just look at her with too much admiration. But when a girl fondles her while another flips up her skirt to check out her panties, she merely asks them - rather weakly - to please stop.
** Her early appearances implied she was developing a crush on ''Lala'', not Rito, and she certainly seems rather fond of Mikan.
* TheDulcineaEffect: If Rito didn't have this, we would have said goodbye to 161 chapters.
* EasilyForgiven: The other characters totally overlook the fact that Yami probably killed dozens of others before coming to Earth.
** In the anime an alien assassin comes after Lala and goes into labor during the fight [[spoiler: Lala helps her to the infirmary and gets her taken care of. EasilyForgiven as soon as the fight stops!]]
* {{Ecchi}}: While certainly not the first manga to incorporate loads of fanservice and ''interesting'' shots of semi naked to naked young women, To-Love-Ru takes the trope to a whole 'nother level to put it bluntly! Darkness somehow manages to crank things up to where you'd swear at times you were looking at a Hentai work, not a fanservicey rom-com!
* EroticDream: Being a healthy young man, Rito has a couple.
** One notable instance in the manga is when Rito was dreaming about Haruna, which lead to an AlmostKiss between Rito and Lala because she was in his bed again.
** The most memorable instance in the anime is actually an induced hallucination, featuring Rito, Haruna, ''and'' Lala.
* EverybodyKnewAlready:
** The schoolwide reveal of Lala being an alien only results in "Oh, that explains the tail". People in TLR are just ''way'' too easy-going about extraterrestrials...
** The usual reaction to new girls is "Oh, are you an alien too?"
** Rito's hidden feelings for Haruna have sort of evolved into this. To Saruyama and Mikan (those that know him best or at the very least longest) his crush is painfully obvious. Risa, Mio, Mikado and Ringo are implied to know, or at least suspect, and [[spoiler: as of ''Darkness'' Lala and Momo know all about it.]]
* {{Expy}}:
** Yami '''is''' ''Manga/BlackCat'''s Eve; not only do they share the same seiyuu, but also the same powers, mother, origin, and [[spoiler: name]].
** The manga throws in "Magical Flame Kyoko", who is TLR's version of Kyoko Kirisaki, including a bounty hunter named "Kuro" (Black), none other than the {{expy}} of Train Heartnet, the protagonist of ''Manga/BlackCat''.
* EyeCatch: Each of which is loaded with {{Fanservice}}.
* {{Fanservice}}:
** The anime. Credits are listed in boob tan lines.
** Summed up pretty nicely in the 'follow-up' chapter released after series cancellation, which features Rito thinking back on everything that's happened since Lala came into his life... ''and it's nothing but six solid pages of fanservice shots from across the series''. In color!
* FantasticArousal: The Deviluke race has their tail's, which are dark red in colour and are tipped with semi-individual shapes, which seem to be particularly sensitive. As Nana explians, while it affects both female and male members of her race, men are in general less affected. However, she also notes that it varies from person to person and that Lala, Nana and Momo are particularly sensitive.
* FinaglesLaw: If an opportunity for {{fanservice}} can happen, it ''will'' happen. Especially when Rito is at the short end of it.
* FirstGirlWins:
** Two possible interpretations; Lala, who appears on the first page of the manga, or Haruna who Rito has known since Middle school. He says he loves them both, meaning this applies no matter who you consider "first".
* FirstLawOfGenderBending:
** Ren was initially one of the more recurring secondary characters, but after Run was introduced she's steadily eclipsed his screentime to the point that he basically only appears for a panel or two each time she has a whole chapter about her.
** While Rito has never been stuck as Riko for very long, after the first time it's happened quite a lot more than any similar oddities Lala's inventions caused.
* FirstNameBasis:
** Lala refers to everyone by their first name, as she is a foreigner (alien), and won't understand this aspect of Japanese culture. Similarly, everyone is on first name basis with her. Surprisingly, this includes Rito, who is the only one to call her without honorifics, implying closeness. The rest use -san or -chii.
** Played with with Haruna and Rito, who are on LastNameBasis. However, at least in Rito's head, it's "Haruna-chan" and not "Sairenji", which is what he actually calls her out loud.
** Rito is also on first name basis with Nana and Momo, though Momo adds the -san [[JapaneseHonorifics honorific]].
** Mikan and Rito too; it's especially noteworthy because whenever Mikan is being particularly [[BigBrotherAttraction bro-con-y]] she switches to "Onii-chan".
** And finally Rito and Run, with Run adding -kun.
* {{Foreshadowing}}:
** The OT3 ending was hinted at as early as chapter ''16''.
** Rito's new favourite brand: KING! Hmmm... trying to tell us something, Yabuki-sensei?
** It's been pretty much a ForegoneConclusion for years that Rito will eventually marry Lala and become the new Deviluke king. The only question still up in the air is whether she's the ''only'' one he'll marry. Certainly not if [[HaremSeeker Momo]] has anything to say about it.
* FreakyFridayFlip: The manga's done this on four occasions: one has Rito switching places with a dog, another has Lala and Haruna switching places with each other, Mikan and Yami, and the last one with Rito and Peke.
* FrickinLaserBeams: Yet another feature of Devilukean tails. Or at least of Lala's and Momo's. As the other Deviluke characters haven't shown whether they can do the same, it might just be a unique personal ability, like Momo's plant telepathy and Nana's animal telepathy.
* FullNameBasis: The cold manner in which Yami-chan addresses ''everyone'' (Rito in particular) except Mikan, which is a telling sign of her fondness for her.
* FunSize: Lala's father, Gid Lucione Deviluke, despite being the most powerful being in the galaxy (capable of singlehandedly destroying planets), looks like an adorable little kid. Justified due using a lot of his power during the Unification Wars.
* FunWithAcronyms: "'''T'''echnology of '''O'''ver '''L'''evel '''O'''peration for '''V'''ery heavy command to '''E'''lectronic control unit" in episode 5 of the anime. The "ru" was there as well, but was listed as standing for "Ru...ru?!.ru.ru.'Run!'" in Japanese, which has the [[DontExplainTheJoke implication that even the maker of the control unit didn't know what to do with that extra "ru".]]
* {{Gainaxing}}: The anime manages to focus on Lala's bouncing boobs even when she's completely covered in shadows. That, my friends, is ''talent''.
** The intro for the first seasons OVA's basically consists of nothing but this with ''every'' female cast member [[spoiler: Even Rito's female form, Riko. ]]
* GalacticConqueror: This is what Lala's father does for a living. [[InsignificantLittleBluePlanet No pressure, Rito.]]
* GenderBender[=/=]InvoluntaryShapeshifting:
** Justified for GenderBender, due to Ren's species able to transform into the opposite sex at will, and InvoluntaryShapeshifting because he cannot control it, courtesy of a sneeze. When that happens, he becomes a girl named "Run" that's utterly infatuated with Rito, much to his chagrin.
** Then, purely by accident, Rito ''himself'' becomes a girl. After this, Lala makes a TransformationRay so she can do this to him whenever she wants (as of current in the manga, she's used it ''four'' times).
* GenreSavvy: Yui seems to be genre savvy, at least in regards to Rito's [[AccidentalPervert little moments]].
** Momo as well.
* TheGlomp:
** How Lala generally greets Rito, or anyone she regards as a friend, for that matter. Run has done it a few times to Rito, too.
** How Risa and Mio generally greet Yami, much to the poor little one's confusion.
** Celine also seems rather fond of this. Impressively she usually manages to [[AccidentalPervert knock down her target(usually Rito)]].
* GilliganCut: Risa invites/guilt trips Rito into going into her house for some coffee after he spent an entire day with her, largely against his will. He tries to decline and pull away from her, sort of mumbling/muttering, then cue next scene where they're both inside her house.
* GlowingEyesOfDoom: Yami is scary when she is under the effects of a {{love potion}} type device.
* GirlPosse: Rin and Aya are Saki's mascots
* TheGloriousWarOfSisterlyRivalry: Nana and Momo
* GodivaHair: Lala, also combined with IdiotHair (that cute little spiral ahoge on her head); Yami too, {{justified|Trope}}, since for her, [[PrehensileHair more hair means more weapons]].
* GogglesDoSomethingUnusual: in one chapter Rito dons a pair of [[{{XRayVision}} X-ray glasses]] that somehow latch on to his head. This being To Love-Ru, of course, we get to see "Rito Vision" of various girls in their lingerie. At one point, he accidentally adjusts the intensity, which renders them totally nude after that. He also gets some {{fan disservice}}, because those glasses allow to see through male clothing as well. Near the end, Rito somehow ended up under Run's groin, and she sneezes and transforms into Ren in which Rito commented 'has become something much worse' and he passed out.
* GratuitousEnglish: It's everywhere in the opening theme. "So we are never give up", to start with...
* GrievousHarmWithABody: Haruna's reaction to anything that truly ''terrifies'' her is to panic, scream, and wildly beat the crap out of it with the nearest blunt instrument...which is invariably Rito.
* GuiltyPleasure
* HairDecorations: Plenty of them.
* HalfHumanHybrid:
** Magical Girl Kyoko is half human, half flame alien. It's what gives her her powers.
** Also what Rito's children would be if he had kids with Lala.
* HandsomeLech: Yui's brother, Yuu Kotegawa. Shades into ChivalrousPervert when he defends Riko from the perverted principal.
* HaremAnime
* HeavySleeper: All these girls sneaking into Rito's bed while he's asleep—and he doesn't wake up fully even when one of them pinches his face.
-->'''Rito''' (still mostly asleep): "The marshmallow bit me!"
* HeroicComedicSociopath: Magical Girl Kyoko from the ShowWithinAShow acts like one. Her motto is "Whatever the problem is, I'll solve it by burning it," and she means it, too. When General Mojack is giving people afros, how does she solve it? By lighting their hair on fire.
* HopelessSuitor: [[PhraseCatcher As expected of Motemitsu-senpai!]] He'll be instantly and permanently rejected by any girl he approaches!
** Ren toward Lala also.
* HumanAliens: All the important ones.
* HypocriticalHumor:
** Lala admonishes her sisters for running away from home. Rito immediately [[LampshadeHanging lampshades]] the hypocrisy. The same scene repeats itself, pretty much verbatim, when Saki runs away from home and goes to Rito and Lala for help.
** Risa claiming that teasing women is sexual harassment. The look on her face makes it seem like an InvokedTrope.
* IdolSinger: Run becomes one, which is probably to the dismay of her [[GenderBender alter ego]] [[RatedMForManly Ren]].
* IKnowMaddenKombat: When in the game world, Rito notices that "Knight class" Haruna's swordplay seems to derive from tennis techniques.
* ImprobableWeaponUser: Haruna several times uses ''Rito'' as a weapon. A ridiculously effective one at that.
* InnocentCohabitation: Lala lives with Rito and his sister. In a bit of a subversion, no one really thinks they're having sex, causing local LovableSexManiac Risa to wonder "why not?" She sees it as a bit of a waste, actually.
* InnocentFanserviceGirl: Lala's nudity taboo tends to be plot influenced. If the plot calls for her to be threatened and saved by Rito, she will try to cover herself (so she can't defend herself). Otherwise, she'll happily prance around naked, wondering why Rito's demanding she get dressed. Strangely, her sisters are not. But even she has limits, as shown when she once landed from a stumble, straddling Rito's face while wearing nothing but a jacket, giving Rito a full view of her lower half. Even ''she'' was embarrassed at that one.
* InnocentInnuendo:
** Mikan mistakenly believes Lala and Rito are doing something naughty in Rito's room and immediately interrupts. Slightly justified as his hand was glued to Lala's [[FantasticArousal tail]], but contrast Mikan's reaction in the beginning of the series when finding him in bed with a naked girl only leads to dull surprise.
* InsignificantLittleBluePlanet: Invoked by [[FunSize Gid]] when he threatens to [[EarthShatteringKaboom destroy Earth]].
* InstantCosplaySurprise:
** One time when Peke gets confused and dizzy it ends up flying from person to person, changing their outfits into something much more fanservicey.
** A separate time, when [[spoiler:Rito becomes Peke]] he loses control and transforms half the class's gym clothes into extremely revealing costumes, including Yui wearing a ''whipped cream bikini''.
* InterspeciesRomance: Rito and Lala. Rito and any of the aliens, for that matter.
* InVinoVeritas: The second half of the fifth OVA. To summarize [[spoiler: Nana and Momo release a pollen to test Rito. All the girls but Lala begin acting drunk, including Haruna zigzagging between sweet and violent, angry at Rito for not choosing yet, Yui declaring Rito can only do {{Ecchi}} things with her, and Mikan almost confessing her love. Strangely, Rito is unaffected.]]
* IsThatCuteKidYours: Celine is occasionally mistaken as Rito's daughter. An old woman can be forgiven for the mistake, as she looks about 2 and he's 17, so it's biologically possible. Ringo, on the other hand, should know better.
* IWantMyBelovedToBeHappy: When Lala finds out that Haruna and Rito both have secret crushes on each other, she decides it's her duty to get them together so they will be happy. Of course that doesn't change her plans for her and Rito to ''also'' be together...
* IWasJustJoking:
** As part of her character development, Yui occasionally jokes about Rito's [[AccidentalPervert little moments]] instead of snapping at him as she usually does. It's only when she is in a really good mood though.
* IWasQuiteALooker: Old Honegawa-sensei after he gets sprayed by an alien youth-skunk.
* JerkAss: Gid. He told Rito back during their first meeting that he would destroy Rito and the Earth with it. When asked why he would destroy the Earth, he replies "Because I don't like you."
* JerkWithAHeartOfGold: Peke can be rather mean to Rito, although most likely [[ViewerGenderConfusion she]] only picks at him because she wants the best for Lala and doesn't like Rito's indecisive nature.
* {{Kimodameshi}}: They decide to go on one in episode 17, fittingly titled ''The Ghost in the OldSchoolBuilding''.
* LandingInSomeonesBathtub: This is how Lala and Rito meet, with her teleporting into his bathtub.
* LeftHanging: Due to Yabuki's messy divorce, the series "ended" with NoEnding. Thankfully that was resolved and the series was restarted under the ''Darkness'' title (with slight protagonist shift to Demote Haruna to an Extra).
* LegalJailbait: Yami is 24 Earth Years Old... Fanboys, you can stop feeling bad about owning {{Doujinshi}}s of her now.
* LensFlareCensor: Replaces SpeechBubbleCensoring in the anime.
* LethalChef:
** Lala; almost literally.
** It might be literal: since Devilukeans are sturdier and powerful than humans, they managed to survive this, but if that soup was served to Rito or any other normal human...
** May have shades of AlienLunch - many of Lala's failures in cooking are due to using Dark Matter, which is apparently Lala's favorite seasoning.
* LovePotion:
** The chocolates from chapter 40, but of the aphrodisiac variety.
** [[spoiler: Celine's pollen is slightly more traditional, making anyone who comes into contact with it fall madly in love with Rito, and ''only'' him. It only lasts for about 30 minutes, though.]]
* LoveTriangle:
** The three main characters, Lala, Rito and Haruna shift between different [[TriangRelations Types of Love Triangle]] as time goes on. It starts as a Type 5 (Lala is A, Rito is B and Haruna is C). When Lala and Haruna become best friends, it morphs into a Type 12. And then when its revealed Haruna loves Rito as well it becomes a Type 11 (With Lala as B, Rito as C and Haruna as A). Finally, at the end of the manga's original run its a full on Type [[spoiler:8]].
** From a purely romantic point of view it goes from a Type 5, to a Type 4 before finally settling on a Type [[spoiler: 7]]
** When all the other love interests are included it becomes a LoveDodecahedron, expanding to include Ren/Run (in love with different people, of course), Yui, at least one of Lala's sisters, probably both of them, ''maybe'' Yami, Rito's best (male) friend who's in love with his AttractiveBentGender, hints of [[BrotherSisterIncest Mikan]]...things have gotten complicated.
* MadeOfIron: Luckily, Rito doesn't seem to have a health insurance policy that covers constant beatings from angry women... (nervous laugh)
* ManEatingPlant: The Yuuki family has one in the backyard named Celine. It's mellowed down to become a giant, friendly, recurring pet. [[spoiler:Until it, uh, "blooms" into what looks like a preschool infant with a flower growing from her head]]
* MagicalGirlfriend: Lala probably counts, and that's not mentioning [[spoiler:"Magical Flame Kyoko" in the manga's "Trouble Quest" arc]].
* MagicSkirt: Considering how overloaded with {{fanservice}} the anime is, this is quite a surprise, but only present in the broadcast version of the first season of the anime.
* MagneticGirlfriend:
** Lala; after she sets her sights on Rito, it sets off a chain reaction that sees the latter unwittingly gathering a [[HaremGenre Harem]].
** ''Literally'' when a device made by Lala accidentally [[spoiler:"glues" Rito's hand to her tail with [[HandWave a super-powerful magnet]]]].
* MarryThemAll: In the abrupt manga finale, Lala not only doesn't mind the possibility of both her and Haruna marrying Rito but is actively enthusiastic about it. Later, he accidentally says "I love you" to several of the other girls (even though it was meant for Haruna), Lala doesn't mind sharing him with them, too. It's implied that, by Deviluke law, he can practice polygamy when he becomes king after officially marrying Lala. Hooray for the harem? It had actually been foreshadowed as early as chapter 16, in which Rito, Lala and Haruna top a dare coming in first place. Rumor has it that the couple making it through the dare usually ends as a romantic couple. As of 'Darkness' Momo is VERY aware of this trope regarding Rito and the girls. Her dream is to actually achieve this result with her taking an active approach.
-->'''Peke:''' "When Rito becomes King of the Universe, then the rules of Earth won't matter anymore."
* MarshmallowDream: A variation. When Mikan crawls into Rito's bed to catch one of the other girls in the act of crawling into his bed while he's sleeping, he grabs her in his sleep and his mumblings hint that he is acting like he's grabbed the 'marshmallow'. When she pinches his cheek to have him release her, his response is to claim that the 'marshmallow bit him'.
* MarshmallowHell: Taken to new heights: after one of Lala's machines accidentally shrinks Rito to about 5 inches tall, she hides him by carrying him around in her cleavage all day. Naturally, she's not wearing a bra (she never does); he nearly gets suffocated and/or squashed multiple times.
* MarsNeedsWomen
* MasterOfTheMixedMessage: Rito infrequently does this with his less potent suitors, like Nana and Yami.
* MeaningfulName[=/=]ThemeNaming: Lala and her family. Their second names come from different mythological/religious demons: '''Satalin''' = Satan, '''Velia''' = Belial, '''Asta''' = Astaroth, '''Lucion''' = Lucifer.
* {{Meganekko}}: Mio and Aya, they like ScaryShinyGlasses though
* MegaNeko: [[RecycledInSpace FROM SPACE]]!
* TheMenInBlack: Zastin's assistants, Maul and Smutts, at least ''dress'' the part.
* MomentKiller: Lots, though Rito-Haruna moments suffer the most. Mikan also tries to keep an eye on [[AccidentalPervert Rito]] when any of the girls are around, and when waking him up in the morning. She keeps an eye on [[LoveableSexManiac Momo]] in particular.
* MoralMyopia:
** Sure, Lala's a bright, sweet and kind-hearted girl who looks out for and cares about everyone, even ''her romantic rival'', but the fact she's ''never'' shown to be even ''slightly'' disturbed about the fact her father has committed genocidal extermination of millions, if not, ''billions'' of worlds makes you wonder how decent a person she ''really'' is.
** The Devilukeans ''are'' a [[ProudWarriorRaceGuy warrior race]], after all. It's just that the ones we always see are a trio of pampered teenage princesses. Not to mention the revelation that the Great Galactic War lasted for ''[[ForeverWar centuries]]'' (meaning it presumably started generations before any of the cast were born), which would imply that Gid actually ''saved'' countless lives by putting an end to it.
* NakedApron: Lala occasionally does this. For bonus points, it's one of the few things Rito has shown any amount of interest in...at least in the {{OVA}}.
* NakedPeopleAreFunny: Oh, yes they are.
* NiceHat: Lala's hat in her standard costume. ''IT HAS WINGS''! They apparently allow her to fly (note the hat is not held in place in any manner). The manga explains they're anti-gravity wings when they sprout out the back of her bikini in the obligatory BeachEpisode.
* NoblewomansLaugh: In the anime. Just listen to [[AlphaBitch Saki Tenjouin]].
* NoEnding: Initially, Rito was never given an official relationship with anyone. Hopefully, ''Darkness'' will resolve this.
* NotBloodSiblings: Jokingly [[InvokedTrope invoked]] by Mikan to startle Rito.
* NoGuyWantsAnAmazon: Anime only.
* NotHimself:
** A spray Run orders accidentally turns Haruna from sweet and innocent into a pure sadist. Turns into a FunnyAneurysmMoment, given what the real-life inspiration for Haruna turned out to be like.
** And the time an alien cold virus makes Lala act shy and feminine, as opposed to her [[InnocentFanserviceGirl normal]] [[GenkiGirl temperament]].
* NotWhatItLooksLike: This happens so much to Rito, especially in the manga, the very laws of probability weep at the frequency of its occurrence.
* TheNudifier: Lala's personal teleporter has this as a side effect since for some reasons, [[{{Terminator}} it will only teleport the person]]. Any items they may be carrying, including clothes, are left behind. There's also a gas with the specific purpose of dissolving clothing, which Run uses occasionally. It always backfires on her, and fanservice ensues. Later, Lala's attempt to fix this flaw in her teleporter fall rather short: it now allows ''some'' of the person's clothes to be teleported with them. As Rito notes, this isn't actually an improvement over being naked.
* OneMythToExplainThemAll: With the sole exception of the CuteGhostGirl, everything can be explained by alien powers or technology.
* OnlyChildSyndrome: Averted; every main character has a sibling.
* OldSchoolBuilding: Used for the {{Kimodameshi}} where they first meet Oshizu, then briefly turned into a RyokanInn before being destroyed.
* [[TheOnlyOneAllowedToDefeatYou The Only One Allowed to Kill You]]:
** Yami for Rito, although it's just an excuse for her to stay on Earth and become an addition to his [[HaremGenre Harem]].
** Might be played straight when it's Yami for Lala, however.
* OrdinaryHighSchoolStudent: Rito spends quite a bit of time angsting about this in episode 4.
* OurGhostsAreDifferent: Oshizu, [[spoiler:although she does receive an artificial body.]]
* OurDemonsAreDifferent: Despite being called Devilukians, having spade tails, some {{Succubus}} like traits and NamesToRunAwayFromReallyFast for the for the girls(see their character entries)...they really aren't all that scary. Or evil. Momo is probably the closest, but even she doesn't really fit.
* PantyShot:
** Primary method of {{fanservice}}.
** In the anime's first season broadcast, at least, panty shots only show up with tennis skirts for some reason (one assumes because they're [[TruthInTelevision nigh unavoidable with tennis skirts in real life]]).
* ParentalAbandonment:
** Quite a few characters actually, but the most noticeable is Rito and Mikan's parents. Ringo has appeared only twice as she works overseas, and while its implied they see Saibai more often, he's almost never at home (apparently living in his office), proven when he first met Lala after she'd been living with them for at least a few weeks, and that's when she and Rito went to visit him at work.
** The long term effects of their parents' hands-off approach is actually explored somewhat in ''Darkness'', and is cited as the reason that Mikan and Rito are so close. They had no one to rely on but each other.
** Haruna and the Deviluke sisters voluntarily left their parents, the former to live with her sister so she could continue to go to school with her friends, and all the Devilukes ran away; Lala because she was being forced into a marriage, and the twins because they hated studying.
* PhraseCatcher: "As expected of Motemitsu-Senpai!"
* PlantAliens: [[spoiler:Rito's giant plant, Celine, turns into one of these.]]
* PlayboyBunny:
** At the start of the [[RPGEpisode "Trouble Quest" arc]], the Guild assigning "adventurers" their CharacterClass had a staff of Bunnies -- well, actually, multiple copies of one Bunny (there was also a Bunny on the sign outside the door). Then, when Yami shows up, she's been dressed as a Bunny as part of her character class.
** When Rito first suggested Lala should dress to blend in with Earth people, she had Peke transform, of course -- and kept copying inappropriate outfits: a businessman's clothing, a policewoman's uniform, a Bunny... ''That'' one led Rito to wonder in shock where she'd seen it.
* PleasePutSomeClothesOn: Rito's reaction to Lala anytime she shows up in the nude, which is most of the time when they're at home.
* PowerPerversionPotential: A lot of Lala's inventions have this to some degree or another. The teleporter that doesn't take clothes and a device that can control people's bodies immediately come to mind. This is just the tip of the iceberg though...no, ''really''.
* PromotionToParent: In a weird way, both Rito and Mikan promoted themselves to this role for each other in the face of their parents' long absences. It's much more noticeable in Mikan, who is generally more emotionally mature and takes care of the household chores, but Rito, especially in the two's younger years, looked after and protected Mikan, continues to worry over her and goes the extra mile to make sure she's happy.
* PsychopathicManchild: Lala, as a non-villainous example. If you think about it, she fulfills the traits: innocent, strong, very smart, often not considering the consequences of her actions and lacking common sense.
* RelaxOVision: In the anime, Ren's training cuts out several times before different fights to show bathtime footage (of the girls, obviously), instead.
* RobotGirl: [[spoiler:Peke can turn into one.]]
* RPGEpisode: The manga's "Trouble Quest" arc.
* RuleOfCute: Strange alien girls can become students at the school without any form of identification very easily, mostly because they're cute and [[DirtyOldMan the principal is a pervert]].
* TheRunaway: Momo and Nana who ran away from their studies. Lala's of the RunawayFiance variation.
* RunawayFiance: Lala, who ran away because of all the unwanted marriage interviews. She then almost immediately finds a boy she likes and integrates herself into his life, much to his chagrin.
* SceneryCensor: Lala has a ''spade-headed tail'' to go along with her GodivaHair, meaning she can keep all her naughty bits covered '''and''' be stark naked. Of course, since [[FantasticArousal Devilukean tails are erogenous zones]], it's pretty much like she covers up her crotch with her breast.
* ScrewTheRulesIMakeThem: Essentially what Peke tells Rito to do in the final chapter. After all, when you're King of the Universe, why should you follow Earth laws?
* SecondEpisodeMorning: Lala states quite simply, "I wanted to sleep with you".
* SequentialArtist: Yuki's father who treats every page [[HotBlooded like a battle]].
* ShipTease:
** If there are any other points of chapter 157 than to drive Rito/Mikan theorists into a frenzy...
** Some Yui chapters deals with just about the same amount of shipping... and then there's Momo...
* ShirtlessScene:
** Yui's brother's very first appearance was one.
** Rito has had a few in his time, as well.
** Zastin when he is possessed.
** An episode in second season also showed naked Zastin, with just SceneryCensor for the bare minimum.
* ShoutOut: Besides the {{expy}} deal, there's a brief ShoutOut to the ''{{Halo}}'' games in episode 4, with one image showing Rito standing in the sunset of a cratered wasteland holding a gun very similar to the assault rifle from the first game, and another depicting a space battle in the shadow of a gas giant with part of a Halo-like structure and the Covenant capital city.
** The entire character of Run seems to be a ShoutOut to Ran from ''UruseiYatsura''.
** Let's not forget those ''DragonBall'' {{shout out}}s either, such as Lala changing into several different costumes from that series. There's even a ''DragonBall'' reference ''in the first chapter''.
---->'''Lala''': Ah, even though I have a tail, it doesn't mean I'll transform when I look at the full moon.
*** Lala's father Gid, seems to be inspired by this series. Also, when he [[spoiler: Threatens to to destroy the earth if Rito isn't worthy of Lala...in the manga, he implies he doesn't mean with a fleet of Devilukian starships...he implies he'll do it ''personally''. "right now I am suppressing my power. If I were to release it, I could easily crush this planet to pieces."]]
** Yabuki's previous series, ''Manga/BlackCat'', has a tendency to do this. Aside from Yami's conveniently named spaceship "Lunatique" (after "Tearju Lunatique"), the blink-and-you'll-miss-it {{homage}} in chapter 134, wherein Lala plays a target shooting game...dressed as Train, right down to the Hades gun and XIII tattoo. With [[{{Expy}} Yami in Eve's clothing]], of course.
** And of course, when Train, in his Chronos, pre-Saya persona, actually appears.
** Another fun fact: the chapters where Train's {{expy}} appeared have titles that were lifted from two of ''Manga/BlackCat'''s episodes... particularly when [[spoiler:Train saved Eve]].
** Fairly early in the manga, several of the cast go to sing karaoke at a place named Kuro Neko.
** [[{{Mario}} Look very]] [[StreetFighter closely at]] [[http://www.mangafox.com/manga/to_love_ru/v11/c092/9.html this page]].
** During Episode 7 of "Motto To LOVE-Ru" (the second series), Peke is [[http://static.tvtropes.org/pmwiki/pub/images/Peke_JumpSQ_resize_6937.jpg reading a manga]] with [[MayoiNekoOverrun certain familiar characters]] on the cover. [[spoiler: Currently both To LOVE-Ru and Mayoi Neko Overrun! (both drawn by Yabuki Kentaro) are published in Jump SQ. This could also be seen as a fourth wall breaker as the TL-R characters show up in the backgrounds of Mayoi Neko Overrun at least once per chapter, so Peke is reading a comic ''that has her fellow characters in it''.]]
** Rob appears as one of Lala's inventions in Chapter 10 of Darkness
** During Peke's (actually Rito's) malfunction in Chapter 143 / Episode 09 of Motto ToLoveRu, Lala ends up in a tiny swimsuit, Haruna in a PlayboyBunny suit, and Oshizu as [[Anime/HellGirl Enma Ai]].
* SkinshipGrope:
** Haruna's friend Risa tends to feel her and Lala (and any other girl present) up on occasion.
** When Rito's mother meets Lala for the first time, her first reaction is to start feeling her up, though justified because she's a fashion designer and was still in "work mode."
* SlasherSmile: Ghi Bree
* SomethingCompletelyDifferent:
** Episode 20 isn't even an episode of ''To Love-Ru''; it's an entire episode of "[[ShowWithinAShow Magical Kyoko]]."
** There's also episode 23. It focuses sorely on minor character Saruyama's nonsensical DreamSequence composed entirely of references to Japanese historical folktales and period novels, which Saruyama even [[LampshadeHanging lampshades]]. Without knowledge of Japanese culture and folktales (or handy FanSub footnotes), a non-Japanese veiwer will be hopelessly confused.
* SoundEffectBleep: An episode of the ShowWithinAShow ''Magical Kyoko'' in the manga portrayed Kyoko telling a fellow that in thanks for something nice he'd done, she'd "have XXX with you!" (He responded in shock, "Is that alright? [[BreakingTheFourthWall This is a kid's show!"]])
* SpeaksFluentAnimal: Nana and Momo, Lala's twin little sisters, who can talk to animals and plants, respectively.
* SpeechBubbleCensoring
* StalkerWithACrush:
** Run has some tendencies in this direction, especially in episode 16, which focuses almost entirely on her stalking Rito.
** Rito towards Haruna in the beginning, at least a little. Enough that Saruyama teased Rito about it. He very quickly stops as he gets closer to her naturally.
* TastesLikeFriendship: Rito gave Yami a [[TradeMarkFavoriteFood Taiyaki]] when they first met. This created enough doubt in her mind about her mission that she didn't seriously try to kill him long enough for [[BigDamnHeroes Lala]] to show up and correct misunderstandings.
* ThreeShorts: The format to ''Motto To Love Ru''.
* TitleDrop:
** Rito's e-mail address seems to be Rito@[=ToLOVE=]. Its hard to tell the rest, but this should be enough to qualify.
** The example listed under FunWithAcronyms.
** May also happen rather often due to the multilingual pun of To Love Ru being pronounced the same as Trouble; Rito occasionally mentions how his days are filled with ''Trouble'', etc.
* ThanksForTheMammary: Which, for some reason, means a marriage pact in the anime. Also happens fairly often to [[AccidentalPervert Rito]]. By ''Darkness'' he can recognize Lala's chest ''by feel''.
--> '''Rito''': This is a sensation I know all too well!!
* TheTease:
** Risa, so very ''very'' much.
** Momo's no slouch, either.
** [[spoiler: Enter ''Nemesis'', who gives Momo of all people a run for her money. Bonus point for teasing Momo.]]
* TokenMiniMoe: Mikan and Yami are ''clearly'' designed with this in mind. Nana and Momo also qualify, despite Momo being more developed than others.
* TooKinkyToTorture:
** Sorta. See Episode 6 of the anime. Saruyama enjoys being "dissected" by Lala, and the principal asks for "more... more" after being tied up.
** Also, when Haruna got sprayed with a personality-change drug, she made some nasty remarks about Saruyama... and it ''turned him on''.
* TransformationSequence:
** Lala's clothing bot Peke does this for her quite often, but it's thankfully skipped after the first few episodes.
** In the OVA, Mikan of all people does this with Peke's help. She is totally surprised how Peke "forces" her to do the movements Lala normally does.
* TrueLovesKiss: Having accidentally possessed Haruna, Oshizu thought one of these from Rito would wake Haruna's consciousness and free Oshizu from her body.
* {{Tsundere}}:
** Yui's a Type A; her default expression in the beginning seems to be a scowl, and Rito is surprised the first time he sees her smile.
** Saki and Yami in the anime finale: "I'm not doing this for you."
* TwelveEpisodeAnime: The second season, which is just as well as there weren't enough manga chapters left to adapt for a 26 episode season at the rate the ThreeShorts format was burning through them.
* TwiceShy: Rito and [[spoiler:Haruna]].
* UnlimitedWardrobe:
** Sort of: Peke can copy any outfit that Lala asks him to, from casual wear to nurse uniforms. However, too much time spent in clothing-form will cause her to wear down and cause ClothingDamage, and we all know where that leads...
** There's also the fact that if the hat (Lala's primary outfit) or hairpin (all her other outfits) come off, so do the clothes.
** Later in the manga, Peke ends up becoming dizzy and flies from one girl to the other, destroying their current outfits and replacing them with previous outfits Lala wore in the series. When Peke ends up on Rito, it mimics a one-shot joke outfit: a ''whipped cream bikini''...
* UnknownRival: Ren/Run. Saki, too, with her unrecognized "rivalry" against Lala for being the "queen of student body."
* UnmovingPlaid: Prominent art design in Saruyama's DreamSequence.
* UnwantedHarem: Well for starters, Rito didn't ''ASK'' for a hot naked alien princess to teleport into of all places ''his bathtub while he was using it!'' (along with the subsequent [[AccidentalMarriage]]! All he wanted to do was keep trying to confess to the girl of his dreams!
** Nor did the poor sap ask for ''at least'' three to four different cock teases who have all but flat out asked/begged Rito to bang them, a tsundere who secretly likes him and ''also'' wants the D (supposedly at least), despite acting like Rito is a sick pervert (though its not always ''his'' fault perverted shit keeps happening to him), two different assassins; one who ''will'' murder him if he so much as looks at her funny; and one who's intent on making Rito her ''servant'' (read sex slave), and that is probably only scratching the surface!
* UnusuallyUninterestingSight: Lala's tail. A bit of a subversion, as everyone notices, but just thinks it's an accessory of some kind when they first meet her. Even when Rito accidentally reveals to Haruna, [[ThoseTwoGirls Mio, Risa]] and Kenichi that Lala is an alien, none of them think it's any big deal. Aside from thinking that it's cool and explains a lot, they barely react. They're similarly nonchalant about discovering that Ren and Run are [[GenderBender male and female personas]] of [[SplitPersonality the same alien]] and that Yami is an [[VoluntaryShapeshifting alien shapeshifter]]. It soon becomes widely known that the characters are aliens, and nobody at all seems to mind.
** Lala's inventions would also fall under this trope. Possibly averted as Saki's Tenjouin Group also seems to have some interesting technology(more so in the anime). This probably explains why no one was that surprised when Lala admits to being an alien.
* VisualInnuendo: When Risa is [[EroticEating playing]] with a cherry in Motto To Love Ru 10.
* VitriolicBestBuds: Everyone knows [[IneffectualDeathThreats Yami isn't going to kill Rito]]. She may beat him within an inch of his life after [[AccidentalPervert certain incidents]], but she'll protect him just as much as any of her other friends if it matters and no on has any concern about her being around him. Becomes a RunningGag fairly quickly, with Yami saying he is her target and Rito pretending to take her seriously. In one case, he picks her up and carries her to Dr. Mikado when she collapses with an illness.....while taking a swipe at him.
* WelcomeToCorneria: Parodied in chapter 93 of the manga.
* WiseBeyondTheirYears: Mikan, the most emotionally mature and level-headed member of the cast (though with this cast, that's not necessarily saying much, she ''is'' quite mature). Also the youngest.
* [[YouGottaHaveBlueHair You Gotta Have Colorful Hair]]:
** Lala, among others of the cast.
** Notable in that only aliens have impossible hair while humans are shown with realistic hair colours.
** Rito's (and his mother's, probably) red hair is unusual in Japan, except if he's descended from [[http://en.wikipedia.org/wiki/Red_hair Scotland]], and even there, red hair is damn rare (about 13%, with an additional 10% or so carriers of the gene). But yes, it was technically [[RealityIsUnrealistic Realistic]].
*** There ''are'' natural redheads in Japan. They make up less than 1% of the population, and due to Japan's rigid social structure and distaste for anything "different", nearly all of them dye their hair black to fit in.
** [[InformedAttribute Haruna's hair]] [[HairColorDissonance is apparently black]], though in most materials and colour pages, it's violet. Presumably, this also applies to Akiho, her CoolBigSis.
* ZettaiRyouiki: The school uniform is a Grade A example. Probably due to the [[DirtyOldMan principal]]. Nana is a ''Grade S''.

!!''To Love Ru Darkness'' provides examples of:

* AboveTheInfluence: Averted, subverted and played straight in one sequence. During Yui's visit at Rito's, Momo tries to setup a special mood between them, which is seemingly about to be disrupted by their usual antics. She considers an aphrodisiac, but dismisses that thought as she feels it is not appropriate. Then Yui herself makes a move on Rito, but is basically shot down by Rito.
* AlmostKiss: Rito and Yui, who is wearing nothing but a shirt.
* AllMenArePerverts:
** [[CaptainObvious Traditionally]].
** [[IfItsYouItsOkay Kotegawa]] [[CharacterDevelopment accepts this.]]
* AnchoredShip: Rito refuses to move forward with Lala until his feelings for Haruna are resolved. Presumably, this involves a confession.
* ArtEvolution: Compare how the characters looked at the beginning of the series to how they look now in Darkness.
* AttemptedRape: Probably the most outrageous example has to be [[spoiler: Nemesis when she teleports into Rito's bathroom when he's bathing himself]]
* BarbieDollAnatomy: Averted. Nipples and genitalia are drawn, but the latter are obscured or otherwise hidden, and are only indirectly revealed.
* BlindWithoutThem: Tearju
* BlondeBrunetteRedhead: The three LivingWeapon characters: Yami, [[spoiler:Nemesis]] and Mea.
* BookEnds: At least in the anime, it starts off with Momo on top of Rito and ends that way.
* BreakoutCharacter: Yami, though one can argue Momo's getting just as much the protagonist spotlight.
* CallBack: One of the side chapters is about Haruna being turned into a cat and Rito petting and bathing her. The entire thing is a role reversed call back to a chapter in the original To Love Ru where Rito is turned into a dog and Haruna does the same. To drive the point home, Rito even remembers that time while bathing Haruna, not knowing it was her.
** A rather brilliant one in Chapter 34, After Peke advises Lala in the previous chapter to start considering her feelings for Rito and after [[spoiler: Momo of all people shows her a 18+ dating sim, Lala decides to surprise Rito by teleporting into his bathroom much like she did (by accident) way back in the beginning of the series. Only this time, Rito doesn't completely flip his shit and Lala wants to experience a kiss with him...]]
* CharacterDevelopment: For Yui when she and Rito get trapped in "the rain", ending up in Rito's house due to [[spoiler:Momo's trickery]] and use of a shield that projected the rain. Then Yui basically [[spoiler: offers herself to Rito after one of his AccidentalPervert moments]], and Rito appears to almost [[spoiler: ACCEPT this offer without any sort of "freak out" in a CrowningMomentOfHeartwarming]]. She even ends up [[spoiler: ''defending'' Rito when Risa spins her {{DayInTheLimelight}} to tease Haruna. Yui says she knows that Rito wouldn't actually do what is being implied. ]].
* CelibateHero[=/=]ChivalrousPervert:
** Apparently Rito has upgraded himself to these.
** He also against molestation of all forms, PlayedForLaughs. Then again, see GettingCrapPastTheRadar, there's additional [[DoubleEntendre images]] [[PensieveFlashback that we never saw before]].
* CrapsackWorld: Run and Ren's home planet Memorze has been revealed to be this. It's a planet where there are two suns, locking the planet in eternal day time. 80% of the planet is dry desert and the rest is also inhospitable, so much so that the dual-gender bodies evolved in order to help survival in a land with little food and water. Only trade with other planets has given the people relief.
* CringeComedy: Though mostly played for sexiness, there is definitely an element of this to Rito's AccidentalPervert moments in ''Darkness''.
* DarkerAndEdgier: ''Faintly'', in the sense that there is now an actual ongoing conflict revolving around [[DarkAndTroubledPast Yami's backstory]] in addition to the harem antics.
* DatePeepers: Momo, Mea, Nana and Yami all travel in a group to follow Rito and Run on a date, though for different reasons. [[spoiler: Yui also follows them, though we aren't shown her doing this until she and Nana burst out to interrupt the date]].
* ADateWithRosiePalms:
** Semi-invoked with Momo, who looks like she's fighting off the urge to play with herself every time Rito gets into an ecchi situation.
** She more or less gets away with this on-screen in one of extra chapters. How, you may ask? She's thinking about Rito [[FantasticArousal while rubbing her tail]]. Despite not technically being masturbation, it gets the point across well enough, especially when Nana walks in on her.
* DefrostingIceQueen: Yui. Chapter 4. That is all!
** Aside from the harem building, the other major driver of the story is Yami finally thawing from light ship teasing to fully accepting both Rito and her life on Earth.
** Yui is also defrosting at an even quicker pace than before.
* DefusingTheTykeBomb: Probably one of the oddest cases out there. [[spoiler:It's later revealed that the eponymous "Darkness" is in fact Yami's {{Manchurian|Agent}}-esque SuperpoweredAlterId who was supposed to use the full extent of her powers to deliver indiscriminate destruction in a ''planetary scale'' as her creators' way to say "frak you, galactic peace". It turns out that's no longer the case because after a year or so of frequent [[AccidentalPervert "accidents" courtesy of Rito]], Yami ended up enjoying them on an unconscious level. End result: Darkness!Yami runs on her instinctual drives and thinks of Rito as the embodiment of everything it's perverted, good and feels better in the universe, which is bad news for him because in that state her idea of "becoming one with him" involves his death.]]
* DefyingTheCensors: Seems to be doing this in response of the outrage of MoralGuardians towards fanservice. Both a higher density and more risqué fanservice are prominent which show no signs of letting up.
** Supporters of one of Japan's recent censorship laws cited ''Darkness'' specifically as a reason for its passage. Yabuki's response? Take the fanservice [[SerialEscalation up a few notches]], essentially ''daring'' the government to try and stop him. The series was later specifically found not to be in violation of the law.
* DemotedToExtra: Several members of the harem have had drastically less screen time as of Darkness, while the little girls have received much more focus.
* DidYouJustHaveSex: Nana seems to be about to ask this of Rito, though it's more a case of [[DidYouJustHaveSex Were You Just About To Have Sex?]]
* DoubleStandard: In Chapter 9, Momo and Mea get ''very'' excited by their fantasies about Rito finally losing control and ripping Run's clothes off. And Yami doesn't clobber them or even seem angry; she merely remarks "what a bunch of ecchi people."
* DoubleStandardRapeSciFi:
** The rapist in question was being mind-controlled into doing it so she's not to blame. The one controlling her on the other hand... [[spoiler:Fortunately, Momo was on hand to beat the perpetrator within an inch of her life, before turning her over to Zastin to be imprisoned.]]
** Subverted when Mea hijacks control of Rito's body and forces him to lick her all over while simultaneously forcing a MindLinkMates scenario in order to share his senses - while no one calls her on it, she admits that she's using it as a punishment because she knows how uncomfortable it makes him. Meanwhile, Rito uses the opportunity to read her mind...
* DoubleStandardRapeFemaleOnMale: [[NiceGuy Rito]] [[ChivalrousPervert would like to object]].
* DudeShesLikeInAComa: There are some serious rape undertones when Mea straddles a sleeping Rito and gives this comment:
--> '''Mea''': ''[[InnocentInnuendo If we join together]], I might find out what kind of person you are'' ?
* EstablishingCharacterMoment: The fact that she is female, reasonably attractive, the right age and [[HaremSeeker Momo]] ''doesn't'' try to set her up with Rito is a unique one of these for [[spoiler: Nemesis]].
* {{Expy}}:
** Mea Kurosaki a.k.a. [[DarkerThanBlack "Alien Suou"]].
** Kyouko Kirisaki is based on her namesake from ''Manga/BlackCat''.
** As is Tearju Lunatique.
* {{Fanservice}}: Taken to ridiculous levels. The first chapter manages to somehow increase the amount of Fanservice compared to the original, edging dangerously close to {{hentai}} at points. The fact that it blatantly averts BarbieDollAnatomy probably has something to do with this.
* {{Fetish}}: ''Darkness'' has shown us that some of the girls are developing these, particularly Mea who has shown great interest in licking, while Haruna is developing a fascination with bathing.
* FirstNameBasis: Haruna once calls him "Rito-san" when she was thinking about him alone, but uses "Yuuki-kun" when they next meet face to face.
* GenreShift: The manga started out as a fairly standard harem where the only girls who actually had a chance of winning were Lala and Haruna. By the time of Chapter 14 in Darkness, it's combined multiple aspects of ''Manga/BlackCat'' (whereas it only had a few callbacks and Yami herself in the original series) and morphed into a modern ''TenchiMuyo'', complete with MarryThemAll in the works (or at least with Momo actively scheming to make sure it's in the works). It's also become quite a bit more character driven, with character arcs focusing on various girls and less random wacky comedy.
* GettingCrapPastTheRadar: ''To-Love-Ru Darkness'' may as well be subtitled "How can Yabuki sneak glimpses of the girls' vaginas past the censorship laws this month?" Quite possibly the most clever bit so far is when a panty-less Yami-chan is falling towards Rito's head. Rito's eyes look like they're just drawn with pupils, but zoom in some and you can see that the outline of them is actually... well.
* HaremSeeker:
** An interesting inversion: Momo, one of the girls in Rito's {{Harem}}, wants to create the harem for him, with her in it, and pretty much every other female he has ever met. [[spoiler: She thinks if he is forced to pick one, it probably wouldn't be her....so.... ]]
** The example provided only reveals one character who MIGHT hold feelings for another (less love, more of a crush), and showed reasonable amounts of incentive to fall in love with Rito.
* HeadbuttThermometer: used by Rito to check Mikan's temperature in 8.5
* HotterAndSexier: Think the original was overloaded with {{Fanservice}}? Sorry, but Yabuki thinks otherwise.
* IdiosyncraticEpisodeNaming:
** Topic in English~A Flowery Description About Said Topic in Japanese~
** The exception here is the first four chapters, which simply say the same thing twice, but with the same structure. The prologue chapter is an odd one out, using the title "Prologue~Prologue and Activation~".
* IfItsYouItsOkay[=/=]SingleTargetSexuality: Momo, Mea, Lala and Haruna all mention how cute female Rito is. Momo and Mea even go as far as groping and licking him while he's in his female form.
* ImagineSpot: Momo has one of the heavily censored kind when she thinks of Rito. And multiple somewhat less censored ones of how she hopes things will turn out during Rito's time alone with various individual harem-candidates. The actual events are invariably tamer than what Momo is hoping for (though still very much NSFW thanks to his AccidentalPervert nature).
* InnocentInnuendo:
** Yuuki Rito is a beast.
** DoubleEntendre: or single entendre? Besides from referring his AccidentalPervert nature, it also implies [[BiggusDickus something else]].
** Mikan mistakenly believes Momo and Rito are doing something naughty after hearing a bit of suggestive dialogue. It turns out that they're just playing a video game. Mikan even lampshades the familiarity of the scene. Of course, this being Momo (who notes she didn't sneak into Rito's bed "this time"), the innuendo probably wasn't so innocent at all.
* InVinoVeritas: [[spoiler:Haruna gets drunk on Devilukian cola Nana gives her. She ends up clinging to Rito ([[FanService while half-dressed of course]]) and rambling about how he is hers and about Momo's harem plan. She's aggressive enough that even Rito starts to get a clue.]]
* IWasJustJoking: Yui waves off her implication that [[spoiler:she would be willing to sleep with him if he only did it with her]] as a joke, when in truth she was completely serious.
* LongLostSibling: Yami has one, and she really wants Yami to kill Rito and come home. Complicated by the fact that she's ''also'' attracted to Rito.
* LiteralSplitPersonality: [[spoiler:At the end of chapter nine Run goes through a metamorphosis that her species goes through when they reach adulthood. The result? Ren and Run are pulled apart from one another and they become two separate people. They're both absolutely thrilled by this development.]]
* ManIFeelLikeAWoman: Unlike the first few times Rito got turned into Riko, in ''Darkness'' he decides to check himself out in a mirror and feel his breasts. He promptly decides that they'll just get in the way. Only he gets caught by Momo in the process, who tells him that if he wanted to experience the female form, he could have just asked her.
* {{Meido}}: When Saki [[LethalChef makes her mansion staff sick with her cooking]] she recruits people to help out for a day. It ends up with Mea, Nana, Momo, Yami, Aya and [[NinjaMaid Rin]] dressed up this way...because [[LoveableSexManiac Momo]] thought the Tenjouin maid uniforms were "to orthodox and lacked sex appeal"....er, because she [[BlatantLies "didn't want to be a burden on Tenjouin-san." ]]
** As a bonus: [[spoiler: When Nemesis makes a[[TheCameo brief appearance]]...she's wearing ''the same uniform''. Only Mea sees her, so it could have been in her head. ]]
* MundaneUtility: Yami and Mea demonstrate that, yup, VoluntaryShapeshifting can make cooking and cleaning pretty cool.
* MyGodWhatHaveIDone: PlayedForLaughs in the chapter 26 of ''Darkness''. Haruna's older sister [[spoiler:walks in to Rito and Haruna while the latter is wearing a little more than her underwear and draws the obvious conclusion. After Rito excuses himself (read: runs for it), Akiho goes into a breakdown while ''apologizing'' to Haruna for interrupting her time with Rito and remains in such self-recrimination for apparently hours after the fact.]]
* NoodleIncident: Yami, a legendary assassin, is afraid of wriggly, slimy things because she once got lost in a planet with tentacled animals. She refused to elaborate.
* NotHimself: Rito in an extra chapter. Thanks to one of Momo's plants, he becomes a pervert and abuses Lala's inventions. He even agrees to the Harem Plan under its effects.
* PensieveFlashback: Mea induces something like it in chapter 3. May or may not have been influenced by the dream-like state Rito was in at the time. Something was added on that we didn't see before though.
* PornWithPlot: ''Barely'' short of actual sex (Momo's fantasies REALLY push the envelope), the Fanservice in the sequel is so intense that in Taiwan it is outright slapped with an R18 sticker and sold in such sections.
* SelectiveObliviousness: Rito clearly does this about his new batch of Harem (see ChivalrousPervert above).
* SerialEscalation: While the original was Fanservy enough, every chapter of ''Darkness'' seems to be trying to top itself. With the way things are going, very few people are going to be surprised if somebody ends up getting screwed silly.
* SeriousBusiness: Momo really wants to get herself and just about every other girl she knows laid by the same dude. She has intricate {{plan}}s and strategies to achieve this.
* SexyShirtSwitch: {{Invoked|Trope}} by Momo, switching a tracksuit for Yui (at Rito's house) for only one long-sleeved shirt.
* ShipperOnDeck:
** Momo's trying to create a harem for Rito, after all. She appears to be considering each and every female except Peke and his Mom as a love interest.
** Lala also fully supports Rito/Haruna, with the added twist that she is hoping that it'll lead to Rito/Haruna/Lala.
** Risa (and her best friend Mio) seems to be pushing for the Rito/Lala ship, and has been nothing but helpful to Lala in trying to get them together, albeit in [[TheTease her own way]].
** Nana is the edge of this when it comes to Rito/Lala and Rito/Haruna.
** Mikan appears to want Rito/Lala, considering she keeps chastising Momo for coming on to Rito, saying that it'll make Lala upset. However, this could also be due to her own jealousy.
** Yuu wants Rito/Yui, although he is sympathetic to Rito's trouble-filled life.
** Saruyama has often helped to encourage the Rito/Haruna ship.
** Oshizu supports Rito/Haruna. Using her ghost powers. Usually ends in {{FanService}}.
* ShipTease: Chapter 14 is a huge ShipTease between Rito and Yami.
* TakeThat: Yabuki upped the fanservice in response to the pressure to harshen the measures against borderline material and the anti-pedophilia law that's being discussed right now.
* TooHotForTV: Averted! Against all odds, Darkness somehow managed to get adapted into a ''TV series'', despite the HotterAndSexier elements.
* TookALevelInBadass: Several characters, but Rito took this in terms of personality instead, what with his being a legitimate ChickMagnet instead of the [[UselessProtagonist whiny]] HotBlooded HaremHero we knew. Basically, when he's serious, either him or someone badass will hammer the plot.
* TooKinkyToTorture: Mea: after Nana's pets go on a rampage and [[BlackComedyRape lick her all over]]she...develops a fetish for it.
* UmbrellaOfTogetherness: On the cover of Volume 3. Amusingly, the other name is scribbled out leaving only [[http://i1115.photobucket.com/albums/k541/ledtumi/v3.png Rito's name legible]].
* WhamEpisode: Chapter 39.
* WhenSheSmiles: Yami's big pleased smile is unexpected but definitely not unwelcome.
* XanatosSpeedChess: A minor one developing between Mea and Momo and it's a race to see whether the latter's "Harem Plan" will prevail or whether Yami will carry out her original mission to kill Rito. Mikan, Rito and Momo's "wake up" routine could fall under this also. [[spoiler:Currently, the main game is between Momo and [[BigBad Nemesis]] over who should win Rito.]]
