* AmericansHateTingle: Naru. She came in first place in the Japanese character poll. In the United States, she doesn't share that universal appeal, especially her anime incarnation.
* BaseBreaker: Naru is either an hilarious {{Tsundere}} who brings up a lot of the humor, or a horrible DomesticAbuser who should be thrown in jail. (Again, this is more her anime incarnation. She's more liked in the manga thanks to her CharacterDevelopment, although even there, she still tends to push the limits of UnprovokedPervertPayback very close to DomesticAbuse Territory.)
* CanonFodder: Whenever a throwaway line of dialogue is needed, one of the characters, usually Keitaro, says some variation of "...It had three holes, and I really wanted one." The mysterious object with three holes is never revealed, and is probably an inside joke among the creators.
* DryDocking: At least one fan was ''very'' happy that Keitaro ended up with Naru, leaving Motoko single.
* DudeNotFunny: A common criticism for the series is Naru's violent tendencies bordering on DomesticAbuse territory.
* EarWorm: The anime's theme song grows on you... a lot.
* FanPreferredCouple: Mutsumi and Keitaro, Motoko and Keitaro, Shinobu and Keitaro...
** Pretty much, Keitaro and anybody who is not Naru, at least among [[AmericansHateTingle American fans]].
* HilariousInHindsight: Kanako becoming Naru's [[spoiler:sister-in-law]] (in the manga at least) is quite funny since their respective [[Creator/DorothyEliasFahn English]] [[Creator/MelissaFahn voice actresses]] are in-laws in RealLife.
* JerkSue: Many fans see Naru this way, due to her [[DoubleStandardAbuseFemaleOnMale knee-jerk reactions]] to whatever Keitaro does; made worse since [[AccidentalPervert it's usually unintentional.]] Yet, she never gets called out on it, or suffers any karmic backlash, at least in the anime (and in the manga it takes A LONG TIME to happen).
* LesYay: Naru and Mutsumi in the shower shortly after Mutsumi is first introduced in the manga.
** While Keitaro is away, Mutsumi "dresses up" as him (by putting on glasses and rearranging her hair) in the hot springs and puts the moves on Naru. While the reason she gives is to merely try and make it easier for Naru to express her feelings for Keitaro, Cue Naru {{Megaton Punch}}ing her by mistake.
** When Kanako first arrives in ''Love Hina Again'', she disguises herself as Naru and feels up a number of the residents of Hinata Inn as research for her disguises. Motoko's "examination" takes place in an alleyway, and draws quite a crowd of {{nosebleed}}ing men.
*** Much more discreet in the manga, where Kanako-as-Naru attacks Motoko inside the Hinata House, using the convenient pretense of privately teaching her about what could be in the entrance exams.
* {{Moe}}: Shinobu. With those vulnerable eyes, [[LuminescentBlush luminscent blushes]], embarrassed stutterings, and that impossibly cute squeal, how could anyone ''not'' want to hug her?
* MoralEventHorizon: The girls cross it in the Spring Festival when they kidnap Keitaro's two friends and start torturing because they think that they might know where Keitaro went. When they beg Naru for mercy, she cruelly orders the girls to continue torturing them. Remember folks, these girls are our heroes!
* RonTheDeathEater: The hatred some fans have for Naru or Motoko (or Kitsune, sometimes) reaches ridiculous levels at times...
* ShipToShipCombat: Put a Motoko/Keitaro and a Naru/Keitaro shipper in the same room. There '''will''' be blood.
** And don't add a Shinobu/Keitaro shipper. You risk getting an EarthShatteringKaboom right in your face.
** Even worse: bring in a Mutsumi/Keitaro shipper. '''Say your prayers, everyone.'''
** DieForOurShip: Either Motoko is an abusive bitch without any sympathetic traits and wants to steal Keitarou from Naru, or Naru is a cruel DomesticAbuser who should be tied up and forced to watch as Motoko marries Keitarou.
* SubbingVsDubbing: LoveHina is pretty infamous between voice actors and fans alike for being ''a royal pain to dub'' in almost every language. The Mexican Spanish, German and American dubs are some infamous cases, especially the Mexican one, which practically destroyed the perception of the franchise in Latin America.
** The English dub subverted this and it managed to include also the [=OVAs=] too.
** On the other hand, the Mexican Spanish translation of the original manga has an excellent translation, handled by the same translator who translated the scripts of both ''Anime/SailorMoon'' and Anime/CardcaptorSakura's animated adaptations to Mexican Spanish.
* UnfortunateImplications: "If you're a [[DoubleStandardAbuseFemaleOnMale male in this series... it's A-okay to harrass you, beat you up, treat you like a thing]], and call [[AccidentalPervert you]] a [[AllMenArePerverts pervert]] even if you're not. ''And'' [[TheUnfairSex you'll have to apologize to your own abusers, no matter how in the wrong they are, simply because they're women]]!"
** The fact that Naru is based on KenAkamatsu's [[WriteWhoYouKnow wife]] really says a lot about [[DomesticAbuse his home life]].
