One of the two first girlfriends together with Karane. The daughter of a wealthy family is absolutely infatuated with Rentarou and wastes no chance to show it to him. Or to seduce him, for that matter.
----
* BigBreastPride: ''Very'' proud. When Rentarou asks around about Meme, Hakari asserts her estimation that Meme is around her own bust size while taunting [[ACupAngst Karane]] over it. Which makes it [[BreakTheHaughty a bitter pill to swallow]] when it turns out Meme is [[HiddenBuxom even]] ''[[HiddenBuxom larger]]''.
* CovertPervert: Likes to show a prim and proper image, but in private, she's very physical in her affection and not ashamed of it. Another notable trait [[GenerationXerox inherited from her mother]]. The covert part is almost non-existent later in the series, as her perverted habits become well known among everyone.
* ADateWithRosiePalms: Possibly referenced. It's repeatedly shown that Hakari's body is... unusually sensitive, which the volume 5 extras attribute to her "[[UnusualEuphemism daily pursuit of knowledge]]".
* ADayInTheLimelight:
** After debuting in Chapter 1, she gets more attention in Chapters 15 and 16, when her mother holds her prisoner in their home until the conflict is resolved.
** Chapter 103 has Hakari's desires in overdrive after watching a movie with a racy scene in it, and she spends the entire chapter trying to find ways around Rentarou's CelibateHero mindset.
* DeadpanSnarker: At either Karane or Hahari’s expense. Sometimes insincerely, sometimes blunt like a bat (mostly Hahari.)
* DeconstructedCharacterArchetype: Being closer to Rentarou on their CrashIntoHello, she is technically the First Girl, and unlike how the first girl tends to be an overly perfect person with little personality, Hakari is [[BeAWhoreToGetYourMan one of the most aggressively sexual]] and devious girls, possibly because she wants to cement her "claim" ahead of the others. At the same time, she's ruled by her feelings to the point that she doesn’t understand them, and [[GenerationXerox her mother couldn’t help her with that]].
* DisappearedDad: Her father died from a terminal illness shortly before she was born.
* DrivenToSuicide: Is willing to jump to her death if she can never see Rentarou again. Fortunately, it doesn’t come to that.
* EstablishingCharacterMoment: The reason she and Karane are introduced at the same time is to make it clear that most of the annoying harem cliches will be averted, as they both accept the idea of sharing Rentarou instantly, as well as letting other girls in.
* EveryoneHasStandards: Hakari is a shameless pervert when it comes to Rentarou, but she does have her limits.
** She's horrified upon seeing an ImagineSpot with Chiyo tied up, stating that showing a young girl in such a position isn't legal.
** She's frequently disgusted by her mother's even more perverted antics.
* FailureIsTheOnlyOption: Played With. Rentarou [[LoveFreak being who he is]], he’s affectionate towards Hakari either way. But any attempts she makes to seduce him or just get his attention on her own terms are always doomed to fail. Typically because Rentarou is too clever or too pure to fall for her tricks. She’s fully aware that the manga itself would never allow her to win, to the point where she [[spoiler: hallucinates beating him in a sumo match and stripping naked to glomp him.]]
* {{Foil}}:
** She's all feelings, in contrast to Nano’s rational viewpoint.
** Her tender attitude and cunning nature is a contrast to Karane's rudeness and bashful dishonesty.
** While Hakari and Hahari are both lustful, Hakari is comparatively more restrained in who she targets, how many she targets, and what she'll do to them, and takes a dim view of her mother's childish behavior.
* ForgottenFirstMeeting: She and her mother met a kindergarten-age Momiji at a moon-bounce, and cemented Momiji's love of touching soft things.
* GagBoobs: Quite a few of the jokes in the [[BreatherEpisode breather chapters]] relate to the size of her chest.
* HeroicBastard: It's never commented or brought up after Hahari's appearance and past, but Hakari's parents were ''never'' married despite being in love. {{Justified|Trope}} since Hahari and "Father-in-law" were only ''13''[[note]]Meaning they can't legally wed, as the legal marriage age in Japan for a male and female has to be 18 and 16 respectively.[[/note]], with the latter dying from a terminal illness and the former going through an impulsive decision of getting an IVF so they could be a family after his death.
* LivingEmotionalCrutch:
** Rentarou is this for her as a result of her own deep infatuation and being tied to him as his soulmate. When her mother intends to separate them, Hakari is more than willing to end her life there.
** She was this to her mother Hahari, as the latter's existence saved her from the despair after the death of her father.
* LoveFreak: Not as bad as Rentarou (Which says nothing at all, it's a high bar), but it seems that ''anything'' he does will make her swoon over him no matter how over the top.
* MadeOfIron: Or at least has a high pain tolerance. She is only slightly injured from getting hit square in the chest with a baseball, and recovers in seconds, despite it going fast and despite getting hit in the chest being almost as painful for girls as [[GroinAttack getting hit in the balls]] is for guys.
* ManipulativeBitch: Is not above manipulating people to get what she wants.
* MeaningfulName: "Hakari" is pronounced the same as the Japanese word for calculating or scheming, alluding to her manipulative tendencies.
* MsFanservice: The first one; she does not hesitate to use her assets to conquer Rentarou.
* RoseHairedSweetie: She has pink hair with flower decorations on it and is genuinely sweet to Rentarou and the other girls. [[PlayingWithATrope But uh... ]] it's more of a cultivated image that she uses to achieve her goals. She's more cunning and manipulative than the usual example.
* ParentalSexualitySquick: As alike as she and her mother are in their feelings towards Rentarou, Hakari regularly gets creeped out at Hahari's questionable fantasies towards both him and the other girlfriends.
* ShamelessFanserviceGirl: She has no issue with Rentarou (accidentally) groping her whatsoever.
* ShesGotLegs: She's got noticeably healthy thighs, something that the manga loves to emphasize. And it’s on purpose, she keeps her skirt up.
* SitcomArchnemesis: To Karane, and it’s Hakari who instigates it. She gets a kick out of poking fun at Karane’s bust size or taking advantage of her {{Tsundere}} nature to rile her up.
* SomeoneToRememberHimBy: She was conceived because Hahari wanted to have children with her dying boyfriend.
* StarCrossedLovers: Her mother subjects her to this trope when she finds out about Rentarou's other girlfriends. It doesn't last long, though.
* StealthInsult: Usually towards Karane concerning her ACupAngst, while still maintaining an innocent and dignified tone.
* {{Stripperific}}: Her idea of a "freedom outfit" is a ribbon wound around her body to hide her private parts and melted chocolate hearts painted on her bare skin.
* ThreesomeSubtext: While she is very close and friendly with the other girlfriends when it comes to her feelings for Karane, they are often shown to be just as strong and sexual in nature as her feelings for Rentarou. You can bet anytime she gets close to or kisses Rentarou she will also inevitably have a similar experience or kiss with Karane. Unlike with Rentarou though, Hakari is shown to get jealous if Karane gets close to anyone else.
* TooCleverByHalf: Rigs a [[DrawingStraws breakable chopstick]] under the assumption Nano will take the closest one on the grounds of being more efficient, only for Nano to say the most efficient course of action is to all draw at the same time.

[[caption-width-right:275:The {{Tsundere}}]]
One of the two first girlfriends with Hakari, a ''tsundere'' at heart due to her feelings of inadequacy but ''cannot'' deny how much she's in love with Rentarou.
----
* ActionGirl: Quite capable in a fight, easily holding the line against the leader of the Gorilla Alliance, a huge and beefy woman.
* ACupAngst: Confesses to Rentarou that she worries that he cares more for Hakari or Nano than her because she’s flat-chested and they’re stacked by comparison. Rentarou assures her that nothing of the sort is the case.
* AngerBornOfWorry: She becomes extremely livid with Hakari after the girl's near suicide attempt.
* AppearanceAngst: Actually played for drama at first. Karane is insecure enough about her own body type that she brought a raincoat to a spa. She even thinks less of herself compared to Shizuka, who has a similar build to her but believes she has a cuteness factor that she doesn't. Rentarou finds her appealing anyway, and she manages to get over it.
* AudienceSurrogate: Serves this role through her reactions to the insane events throughout the manga.
* BadLiar: She might be better at it if she didn’t constantly say something along the lines of [[{{Tsundere}} “it’s not like I did this ‘cause I care about you or anything!”]]
* BadassArmFold: Does one after taking the cape off a Gorilla Alliance member.
* BelligerentSexualTension: She and Hakari are typically at each other's throats, but are shown to be attracted to one another more than they realize or would like to admit.
* BestFriend: It's not clear if it's something she just says in the heat of the moment or not, but when faced with Ahko's old friends dismissing the way they treat her and continuing to say nasty things about her, she declares ''she's'' Ahko's BFF now, and Ahko very much appreciates it.
* BullyingADragon: Downplayed. Karane makes it clear that she doesn't just assault anybody for no good reason, and only responds to teasing with yelling. It's only when someone gets too physically touchy for her (Like MarshmallowHell for example) to tolerate that she throttles them.
* ButtMonkey: Hakari and the narrative itself ''love'' reminding Karane that she has a flat chest. And the other girlfriends' antics test her sanity and dignity every chapter.
* {{Catchphrase}}: "It's not like I'm X or anything!"
* CovertPervert: Far more covert than Hakari or her mother.
** When the decision has been made to peep on Rentarou in the bath, she immediately caves before they can even try convincing her, claiming she doesn't want to fall behind the others. [[SuspiciouslySpecificDenial And definitely not because she was interested in his body or anything.]]
** She will vehemently deny any attraction to Hakari, but then blush furiously whenever the other girl gets intimate or anywhere close to her. She also uses ACupAngst style jealousy to hide the fact she has a large breast fetish.
** When Hakari's desires are out of control, Karane explains that it happened after the two of them and Nano watched a movie with an adult scene in it. It then flashes back to Nano's perspective after said movie, [[HypocriticalHumor showing that Karane was out of commission in exactly the same way]].
* CursedWithAwesome:
** Her Tsundere-ness causes her no shortage of angst, both comical and non-comical. It's also revealed to be the source of her unusual strength and what makes up her strong will.
** She ''oh-so'' wishes she had massive breasts like Hakari or other girls who're gifted with them, but on the plus side her slim figure means she's ''far'' less likely to succumb to fatigue and cramps like them in more physically active areas, like dancing for idol practice.
* CuteLittleFangs: As befitting her tsundere nature. They’re visible whenever she’s agitated.
* DeadpanSnarker: If something out of the ordinary happens ([[WorldOfWeirdness Which is ordinary in this series]]) and Karane is there, expect her to snark at it.
* DeconstructedCharacterArchetype: Acting like a tsundere means she has difficulty expressing her feelings properly; the LieDetector is a notable example of this as she is lying not on whether or not she loves Rentarou but about how much she loves Rentarou. (She then immediately complains that the machine destroyed her self-esteem, which said machine registers as true) It also makes everyone freak out when she gets angry, as they think she’ll slap someone, despite her having more control over her emotions than that.
* DoubleStandardAbuseFemaleOnMale: Overall {{Zigzagged}}, depending on RuleOfFunny. While she has something of a HairTriggerTemper and can hit Rentarou over tiny misunderstandings, she's also quick to apologize when things are cleared up. On the other hand, one chapter casually mentions she put him in a ''[[AmusingInjuries full-body cast]]'' at least once.
* EstablishingCharacterMoment: Shares one with Hakari; their willingness to share Rentarou immediately shows that the girls aren’t gonna be jealous in this series.
* ExpressiveAccessory: Her hair ties sometimes reflect her mood, drooping when she's upset or sticking straight up when she's excited or mad.
* {{Foil}}:
** Her honesty and directness to Hakari's tenderness and habit of keeping secrets.
** Her straightforward attitude to Shizuka's shyness.
* HeroicWillpower: Or rather "Tsundere factor". Karane's physical strength is tied to her will, as the harem finds out when she takes Kusuri's Tsundere Un-maker drug. Without the parts that make her a tsundere, she's too weak to even beat Kusuri at sumo or harm Iku. Later on, Rentarou realizes that it takes every ounce of her will just to say "I love you".
* HiddenDepths: Is more well-rounded than most tsunderes. She doesn't physically attack anyone at the drop of a hat without a good reason. Furthermore, she's actually so ashamed enough of being a tsundere that she takes an "anti-tsundere" drug and protests reversing the process.
** Chapter 88 reveals that she has a talent for making cookies.
** [[{{Tsundere}} Ironically]], she's been shown to be one of the more emotionally-perceptive characters, and has repeatedly noticed when one of the other girls has been hiding their feelings about something.
* MusclesAreMeaningless: She's a slender petite young girl, and strong enough to toss people like softballs.
* OnlySaneMan: Other than Rentarou, she is most likely to object to wacky hijinks, such as when Hahari encourages the other girls to spy on Rentarou in the shower (Which she goes along with anyway).
* PunnyName: Her full name sounds like ''"Janainda kara ne"'', a very typical ''tsundere'' phrase meaning "It's not like I like you or anything!"
* StraightMan: Something that the family ''and'' manga itself lampshades and pokes fun about. Even Kurumi admits that she's second to Karane regarding this.
* StrongerThanTheyLook: [[MusclesAreMeaningless Slim as she is]], Karane's gone toe-to-toe with the Gorira Alliance's leader, nearly broken Rentarou's back with a bear hug, and sent Iku flying hundreds of feet onto a speeding car [[HomeRunHitter with a baseball bat]]. Rentarou believes her strength is tied to her force of will, seeing as she loses it after [[ItMakesSenseInContext drinking Kusuri's "tsundere unmaker" drug.]]
* SuspiciouslySpecificDenial: Karane often says, "It's not like I," before saying what she's thinking or doing, which also makes her a BadLiar.
* ThreesomeSubtext: While she is friendly with the other girlfriends when it comes to her feelings for Hakari, they are often shown to be just as strong and sexual in nature as her feelings for Rentarou. You can bet anytime she gets close to or kisses Rentarou she will also inevitably have a similar experience or kiss with Hakari.
* {{Tsundere}}: Her defining trait. Usually a mild form of ''tsun'' in daily life (mostly shown in her honest, rude opinions) but the ''dere'' comes out rather easily when Rentarou gets in a serious mood.

-->'''Voiced by:''' Creator/ManakaIwami (voice drama)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shizuka_yoshimoto_0.png]]
[[caption-width-right:350:The CuteMute [[CuteBookworm Bookworm]]]]
A tiny classmate and book lover who becomes Rentarou's 3rd girlfriend after bonding over their shared passion for romance novels.
----
* AccidentalPervert:
** She accidentally sees Rentarou naked while trying to stop the other girls from doing so.
** She notices Meme hiding under Mei's dress, and lifts the skirt up to call her out ...only for Meme to [[NinjaLog disappear]], leaving her looking at Mei's underwear. They're both very embarrassed about it.
* AnimalMotifs:
** She has a slight one with rabbits thanks to her innocent cuteness and size. She gains actual bunny ears more than once, courtesy of Kusuri's drugs.
** She has also been compared to a squirrel on more than one occasion.
* {{Balloonacy}}: Is so small and light that she is swept into the air by holding onto ''a towel''.
* [[BigBrotherInstinct Big Brother/Sister Instinct]]: Rentarou's girlfriends and Rentarou himself are extremely protective of Shizuka. When Jurassic High's baseball team [[KickTheDog makes her cry]] to secure a win, [[RoaringRampageOfRevenge everyone kicks into high gear to utterly demolish them]].
* {{Catchphrase}}: "She laughed aloud".
* CompetenceZone: Due to her looks, she is often treated like a small child despite being the same age as Rentarou.
* CuteBookworm: Her defining trait. Loves fantasy romance books with a passion.
* CuteMute: Only speaks with her voice in dire circumstances, because her voice is so naturally quiet.
* TheCutie: Shizuka is one of the sweetest and most innocent members of the family.
* DarkHorseVictory: She’s the one who catches the bouquet, due to having been swept into the air by the breeze, and so caught it in the middle of a fight. She’s also the only one to walk in on Rentarou in the bath, her reaction to which was immense embarrassment.
* DeconstructedCharacterArchetype: Being almost mute caused most people to find her creepy and not associate with her, such that she had no friends before meeting Rentarou, and social interaction terrifies her, making her even more reluctant to speak, and so on. And considering [[AbusiveParents how her mother treats her]], any self-esteem she had would have dissipated long ago. Rentarou and his girlfriends are the first people to be kind to her ''at all''.
* EarlyInstallmentCharacterDesignDifference: Her hair color fluctuated in some of the earlier colored illustrations, ranging from green to brown, before settling with a [[ShyBlueHairedGirl dark blue.]]
* ForgotICouldntSwim: She tries to save Rentarou and Hakari when the duo fall into the Hanazono family pool...and nearly drowns due to being unable to swim, forcing Kusuri to save her.
* FriendlessBackground: Was afraid of even talking to others, let alone befriending them.
* MeaningfulName: Her given name Shizuka means "quiet" (referring to how quiet she is in general), while the characters for her family name translate as "a good book" (due to her being a CuteBookworm).
* MessyHair: It looks a bit unkempt, but it's just naturally curly. When Chiyo straightens her hair, Shizuka's attempts to keep it that way quickly turn into something resembling Whack-a-Mole.
* NiceGirl: Shizuka is a helpful sweetheart, something evident even with her trouble with speaking.
* OlderThanTheyLook: She's a teenager, but her looks, naïveté, and willingness to play a doll game with Kusuri makes that easy to forget.
* PhotographicMemory: Shizuka uses book text to "speak". By Rentarou's observation, this means that she's able to recall the passages of a book so well that she can flip to the page she wants (later scroll to the passage in the app she wants) immediately.
* RelativeButton: She's the button. A rival baseball team making her cry royally pissed the harem off and turned the tide of the game very quickly.
* ShrinkingViolet: Unbelievably bad at speaking up and relating to others (to the point of using book excerpts to communicate).
* SignatureLaugh: Not in the traditional sense. Her actual laugh isn't heard, but she uses ''her speech app'' to narrate her laughter. Even on repeat while being tickled.
--> "She laughed aloud".
* SophisticatedAsHell: Sometimes speaks in excerpts from classic novels, and other times from books that say, "No kiddin', man."

[[folder:Nano Eiai]]
-->'''Voiced by:''' Emiri Suyama (voice drama)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/nano_eiai.png]]
[[caption-width-right:350:The {{Emotionless|Girl}} [[TheAce Ace]]]]
The hyper-rational, intelligent, unfeeling 4th girlfriend, who became moved by Rentarou's sincerity.
----
* AcademicAthlete: She has shown herself to be extremely capable in many physical activities.
* TheAce: Not only the highest-scoring student in the school, but a decent athlete whenever she puts her mind to it, ''and'' pretty enough to have won a pageant over Mimimi with zero conscious effort.
* AmbiguousDisorder: It wouldn't be too outlandish to think she has some sort of psychological condition. Most of her behavior seems consistent with UsefulNotes/AspergerSyndrome.
* BadassBookworm: While it ''usually'' doesn't come to the fore even in the manga's few action-centric stories, it's played gleefully straight in the [[ItMakesSenseInContext maid-uniform watergun fight]], where she uses AwesomenessByAnalysis to match Mei's GunFu shot-for-shot.
* {{Bifauxnen}}: When Hahari has Nano crossdress, she pulls off the look of a {{bishonen}} man very well.
* BlueAndOrangeMorality: She views everything in terms of efficiency, from suggesting poison as a faster means of suicide than {{Seppuku}} to wanting to poke out the eyes of a friend's pets to incapacitate them.
* CannotConveySarcasm: Zigzagged. Her lack of emotion makes it difficult to tell if her comments that would come off as sarcastic from someone else are [[DeadpanSnarker actually sarcastic]] or [[LiteralMinded dead serious]].
-->'''Nano''': (''When Karane jams a piece of short bread into Rentarou's eye without looking'') So this is what "a feast for the eyes" means.
* ChekhovsGun:
** Her fear of heights is first shown in chapter 7 and gets exploited in chapter 26 to stimulate her appetite during an eating contest.
** Her ability to remember an insane number of digits of pi comes in handy in Chapter 83, when she orders the "Jugemu Jugemu Gonzalezurikire Kaijohnnysuigyou-no Suigyoumatsu Unraimatsu Fully-Made-Two Kuunerutokoro-ni Nomutororo Yaburakouji-no Bra-Burglar Paipopaipo Paipo-no [[Creator/ArnoldSchwarzenegger Schwarzenegger]] Shuuringan-no [[GratuitousGerman Guten Morgan]] Guurindai-no Ponpokopii-no Pen Island-no Choukyuumei-no [[Manga/JojosBizarreAdventure Josuke's]] Just Great-as-Hell Challenge Ramen" without missing a single word.
* ColdHam: You know things have gotten wild as hell when Nano foregoes her stoic nature by even a slight amount.
* TheComicallySerious: Nano's humorous moments borrow from her lack of visible reaction to anything and her blunt, calculating nature.
* CutenessProximity: Her brain tends to short-circuit when Shizuka is involved, logic and reason disappearing the minute Shizuka gives her puppy dog eyes. Once when Shizuka was made the subject of Mimimi's "beauty-seeking contest", Nano was only able to identify her "cute" features rather than "beautiful" ones.
* DeconstructedCharacterArchetype: Of the EmotionlessGirl. She’s actually very capable of feeling emotion but has consciously suppressed all feeling because it’s [[StrawVulcan illogical]], so once she feels romantic love for the first time she doesn’t know what to do. At the start, she scorns friendship, and her life seems completely unfulfilling before Rentarou comes along.
* DefrostingIceQueen: One of her defining traits. Her hyper-efficient approach to life made her realize her love for Rentarou but also told her to reject the relation as nothing efficient could come of it.
* DullEyesOfUnhappiness: Her default expression, even after having long accepted her feelings for Rentarou.
* EmotionSuppression: Does not allow herself to feel anything, and freaks out when this fails.
* EyePoke: Nano's preferred method of incapacitating someone is to poke them in the eyes.
* FlatEarthAtheist: PlayedForLaughs in Chapter 52, where she claims that it's pointless to honor the souls of the animals that make up her lunch. Cue Chiyo ''[[MediumAwareness flipping to an earlier chapter]]'' to prove that yes, Heaven exists in this setting.
* {{Foil}}:
** Her rational attitude is sometimes contrasted with Hakari's (who eschews rationality for her feelings).
** She is emotionless due to never smiling, while Mei is emotionless due to constantly smiling.
* FriendlessBackground: By her own choice, as friends are “inefficient”.
* FullNameBasis: How she addresses Rentarou and the other girls.
* GodivaHair: She loses her clothing in chapter 72 when the body-shrinking drug wears off, resulting in this trope when she wakes up in the morning.
* InconvenientAttraction: Unlike most of the other girlfriends she rejects her mutual attraction to Rentarou at first, seeing no purpose to it and attempting to end it. She gets over this at the end of their date, when she finds emotional attachment to photos she took with him at an amusement park.
* IntelligenceEqualsIsolation: Seemingly exaggerated before she started dating Rentarou. It's already evident that she limited her social interactions in her life out of maximizing efficiency, but the way she reacts to the attractions at the amusement park, you'd think she'd never even heard of amusement parks at all before.
* JerkassRealization: Having the chance to develop herself through her love for Rentarou enables her to realize how coldly she came off on Mimimi during the beauty pageant years earlier and apologize to her.
* {{Kuudere}}: After becoming the fourth girlfriend. She's still robotically stoic, but she's more social and caring than her first appearance.
* LudicrousPrecision: One of her CharacterTics is spelling out the percentage of something happening or being true.
* LuminescentBlush: All the girls do this, but with Nano it's the only sign that she's feeling positive about something.
* MouthfulOfPi: She recites a ludicrous number of digits of pi to ''stay focused''.
* NotSoAboveItAll: Participates in trying to see a glimpse of Rentarou naked, and is affected by the drug that makes the drinker want to do nothing but kiss her beloved as much as anyone else.
* PerpetualFrowner: She most likely thinks smiling is inefficient. She doesn't so much as smirk even when she's happy.
* PhotographicMemory: She can easily remember minute details, as demonstrated during the idol training arc and when ordering a ramen dish with a ridiculously long name.
* PrimalFear: She's afraid of heights. During the eating competition, she exploits this in order to stimulate her appetite.
* PurpleIsPowerful: She has purple eyes, and [[TheAce not only is she beautiful and smart]][[note]]She perfected ''every'' subject during the midterm exam, ranking her ''1st'' in the whole school[[/note]], [[ActionGirl she's also got some combat capabilities]] as seen when she was [[MundaneMadeAwesome exchanging shots with Mei on a water gun fight]] or [[BackToBackBadasses standing back to back with Mimimi to hold off]] [[ItMakesSenseInContext Hahari's perverted tentacle hair]].
* SlenderManStandIn: She has unusually long legs, wears a black jacket and tie, shows little (if any) emotions, and was the subject of school rumors before she began dating Rentarou. Also, her reasons behind maximizing efficiency in her life remain a mystery.
* TheStoic: Will have a neutral expression even when everyone else is freaking out.
* StrawVulcan: Has suppressed all emotions, including positive ones, because they are allegedly inefficient. She largely grows out of this once joining the group. She's still as logical and calculating as ever, but values Rentarou and the girls.
* VerbalTic: Uses "Efficient" or "Inefficient" a lot.
* WhiteHairedPrettyGirl: She has glossy silver-colored hair.
* WholesomeCrossdresser: Hahari dresses her in a typical prince outfit to wake up a "sleeping princess" (i.e. Rentarou, [[ItMakesSenseInContext unconscious and also crossdressing]]), and pulls the look off well.

[[folder:Kusuri Yakusen]]
-->'''Voiced by:''' Creator/HisakoKanemoto (voice drama)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/100kusuri.jpg]]
[[caption-width-right:350:The HotScientist and her [[TokenMiniMoe Loli Alterego]]]]
The crazy scientist of the group and the 5th girlfriend. Usually, a small hyperactive girl... until the drugs in her body are neutralized and she reverts to her original form, that is.
----
* BareYourMidriff: When in her original form, as a result of her clothes being too small to fit all the way.
* BerserkButton:
** Kusuri becomes utterly livid if someone messes with her smartphone, as seen when she snaps at her beloved grandmother for slamming her phone on the ground.
** She doesn’t take kindly to other people seeing Yaku as their granny.
* BewareTheNiceOnes: She doesn't show genuine anger until Chapter 84, and it is ''terrifying''.
* BlindWithoutEm: Kusuri can't see very well without her glasses in her older form.
* BoundAndGagged: Gets tied up and gagged by Nano in Chapter 13.
* BrainyBaby: Made her first new drug at eight months old.
* CallingYourAttacks: Tries to do this with a baseball pitch. Nano points out that that is silly and [[AwesomeButImpractical inefficient]], much to Kusuri's confusion.
* CatSmile: Shows up most of the time regardless of the form.
* DeconstructedCharacterArchetype: Represents the kind of HotScientist often seen in fetish works of the kind seen on Website/DeviantArt, and also overly sexualized lolis who are technically okay because [[OlderThanTheyLook they’re actually over 18]]. She vacillates between sexy adult and annoying child due to drug use, and the hilarious side effects of her fetish-enabling inventions actually come with serious consequences. The other characters lampshade her fetish attributes and find them unnerving, especially when she is aged down.
* DualAgeModes: Most of the time she's in her younger form, but she can return to her older form for 10-20 minutes if she takes a neutralization drug. She prefers her younger form for experiments, as her older form has poor eyesight and her hair can get in the way because it's longer.
* EasilyForgiven: There are no hard feelings about her almost trapping the other girls in an AndIMustScream state for the rest of their lives. To be fair, it was an accident, and she feels ''horrible'' about it.
* EveryoneHasStandards: She thinks that Naddy's refusal to "hold back" extends to not bothering with a JarPotty while watching TV, and is disgusted by such a notion.
* ExactlyWhatItSaysOnTheTin: ''All'' the names of her drugs are explanations for what they do. Thankfully for Rentarou and the girls, it gives them enough reason to not take the more dangerous ones.
* {{Expy}}: More or less a scaled-down version of [[Anime/TenchiMuyo Washu]], complete with red hair.
* {{Fangirl}}: She's a fan of the show "Pepepe no Pentarou", which shows in multiple chapters:
** She plays with a Pentarou doll with the others in chapter 29.
** At the karaoke bar, she sings the show's theme song.
** In chapter 91, she's inspired by an episode to pair the girls together as "equipment".
* FormFittingWardrobe: {{Averted}}. Many of her clothes in her default "child" form look rather loose, but that means she doesn't need to change clothes when she transforms back to her "older" form. However, [[SurprisinglyRealisticOutcome said clothes would also likely cover less skin than before]].
* FriendlessBackground: Sensing a pattern here? The difference is that she actually used to have friends before accidentally turning them into {{Technically Living Zombie}}s and alienating everyone else.
* GenkiGirl: Easily the most hyperactive of the girls. Though it's partly because [[CheerfulChild she's physically a child]]. She's more relaxed in her 18-year old form, but even then she can still get cheery.
* GreenEyedMonster: Gets jealous over Kishika calling Yaku 'Gwanny', protesting "She's ''my'' granny, yep yep!", and is wary Kishika is out to take Yaku from her.
* {{Hammerspace}}: Zigzagged. She has a wide variety of drugs that she can produce at any time, but she can't do ''everything'' imaginable with her drugs, and Chiyo does succeed in confiscating ''all'' of her drugs at one point.
* HiddenDepths:
** Gives up the once-in-a-lifetime chance to develop pharmaceuticals in America in order to help Rentarou rescue Hakari.
** She's something of a sumo fanatic and has regularly challenged the other girlfriends to square off against her.
** The reason she invented the immortality drug was so that her grandmother could live forever.
* HotScientist: 18 year old Kusuri is... a sight. It doesn't help that her clothes don't completely fit.
* IdenticalGranddaughter: Her child form looks almost identical to her grandmother Yaku's child form, although her hair's shorter and messier. Her older form looks pretty close to the brief glimpse of older Yaku we've had, but with glasses and, again, messier hair.
* IdiotHair: Has a giant one popping from the top of her head in both forms.
* InnocentlyInsensitive: Kusuri has a habit of casually insulting others without actually trying to, probably due to her child brain. Even when she makes accurate descriptions and compliments, the words she uses couldn’t be more tactless. Even her dead granddad isn’t safe.
* ItRunsInTheFamily: Chapter 74 reveals that not only are her mother and father drug developers as well, but her family have been in the drug-making business for generations.
* ItsAllMyFault: This is her reaction after the kissing zombie arc, as it was her drug that caused the problem.
* KissingUnderTheInfluence: Attempted twice in her introductory arc, but she fails both times. The first time, she serves Rentarou tea spiked with a LovePotion to get him to accept her confession, but he tries to regurgitate the drug when he finds out, and she has to administer a neutralizer when his body becomes overwhelmed by the drug. The second time, she drugs a thermos to get Rentarou to make out with her, but everyone thinks the thermos is for the girls, and the drug turns them into kissing zombies.
* MadScientist: Her defining trait. Good at creating potions that have disastrous side effects. In fact, her changing body is because she tested one of her creations on herself, and it's not the only time she tested drugs on herself.
* MagicAntidote: Almost all of her drugs can be negated with a common neutralizer. The most notable exceptions are her prototype immortality drug (where the effect is only temporary), her de-aging and body shrinking drugs (which would kill the user if consumed too early or at all), her father's bodybuilding drugs (which are actually strengthened by the neutralizer), and the version of the immortality drug used on her grandmother (which can't be negated at all).
* {{Malaproper}}: Frequently mixes up words.
* MeaningfulName: Her family name means "medicinal cooking" and her given name is a homophone for medicine or drugs.
* TheMindIsAPlaythingOfTheBody: Her body also slightly affects her mindset, such as her younger form having the energy befitting of a kid over her older form's slightly calmer disposition, or the latter being embarrassed playing with the Pentarou doll when moments ago she was playing just fine in her child form.
* MyGodWhatHaveIDone: Has this reaction when she finds out the girls drank from the wrong Thermos. She would have quit making drugs altogether had Rentarou not talked her out of it.
* MyGreatestFailure: When she first made the kissing drug, she didn’t know about its side effects, so is devastated when her friends are stuck like that forever. This caused people to avoid her after that, [[MyGreatestSecondChance until she meets Rentarou]], who loves her anyway.
* OlderThanTheyLook: She is 18 and used to actually look it. Then she took a drug that she thought would make her immortal but just made her look like a kid. In this form, she’s shorter than Shizuka!
* OneOfTheKids: Plays with dolls, doesn't really care about safety procedures, and cares more about looking cool with several baseball bats at once than actually playing the game. Though it's shown that the drug that makes her appear as a child factors into this. She’s visibly more ashamed playing with dolls in her grown-up form.
* OOCIsSeriousBusiness: When she drops her childishness and shows actual concern for someone, that concern is well placed. So far, this has happened during her FreakOut when she accidentally turns the girls into kissing zombies, when she chooses to help save Hakari instead of going to America, and when Iku passes out and has to go to the infirmary.
* PoorCommunicationKills: Thinks that it’s obvious which unlabeled Thermos is spiked with a LovePotion — [[MarsAndVenusGenderContrast Rentarou is male so the huge one is for him, while the small one is for the girls.]] Of course, everyone else thinks the big one is for five people and the little one for Rentarou, so when she leaves it unattended the girls drink the wrong one and turn into kissing zombies. And the worst part is that ''this has happened before''.
* ProfessorGuineaPig: Has a very cavalier attitude to testing her drugs on herself. Or on other people.
* PsychologicalProjection: Any time someone else leaves to go somewhere, she tends to jump to the conclusion that [[PottyEmergency they need to pee]].
* RuleOfCool: Tries to play baseball with two gloves and [[Manga/OnePiece three bats]], justifying it with the inherent coolness when questioned. [[RuleOfThree In the bonus page]], she tries to clean the field with two rakes, again justifying it with the inherent coolness when questioned.
* ShapeshiftingExcludesClothing: Kusuri's clothes don't change size when she changes forms, except for her lab coat, which seems to get ''smaller'' in her older form.
* TamperingWithFoodAndDrink: She spikes Rentarou's tea with a LovePotion when they first meet.
* ThirdPersonPerson: As part of her {{Kawaiiko}} aesthetic. This gives her away on two occasions: first when she tries to subdue Zombie!Nano while in her older form, and second when she [[FreakyFridayFlip ends up in Hakari’s body]] due to an unforeseen drug interaction.
* TokenMiniMoe: Parodied. She’s a year above Rentarou, and in her normal form, she’s a bombshell. Unfortunately, an immortality drug gone wrong caused her to look like a child unless she takes a temporary neutralizer. When Rentarou meets her after she reverted back, he has no idea she’s the same woman he felt become his soulmate. And yet she acts the age she looks most of the time.
* TVGenius: Her drugs can pretty much do anything at all, even if [[ItRunsOnNonsensoleum they make no sense]].
* UnaffectedBySpice: Supposedly a side-effect of her drinking so many experimental drugs all the time; it's what [[ThisLooksLikeAJobForAquaman allows her to win the Insanely Spicy Mapo Tofu round of the eating contest]] in Chapter 26.
* VerbalTic: Ending her sentences with "Yep yep!".[[note]]In the original Japanese version, it’s ”nanoda”.[[/note]] And sometimes "Nope nope!" depending on the situation. She does it less in her original form, and by then she only says "yep" once.
* WhatYouAreInTheDark: She's the only one who knows about her drug that makes people able to see infrared, and could easily keep quiet about it so that she can send it to the company she wants to work for. She immediately gives it up to help Rentarou and the others rescue Hakari.
* WomanChild: Justified. She acts like a young child because she's stuck in the body of one. She's more composed in her original form.

Hakari's mother. Overprotective, cold, and focused... until she and Rentarou meet each other's eyes, at which point she becomes the 6th girlfriend.
----
* AbhorrentAdmirer: While she openly lusts after all the girls, daughter included, she has become increasingly attached to Kurumi the most, something Kurumi is less than thrilled about.
* AbsurdlyYouthfulMother: She’s 29. That’s right, she had her daughter at ''13''. This is because she was madly in love with a fellow classmate who suffered from [[VictorianNovelDisease a terminal disease]], and she, knowing he would not survive the year, got herself artificially inseminated with his sperm so that they could be a family before he died.
* AgeGapRomance: With her SecondLove, Rentarou. Being a 29-year-old widow in a relationship with a high schooler, and the oldest member of the harem until Yaku joined.
* AmazinglyEmbarrassingParents: Hahari's perverted antics are a frequent source of embarrassment for her daughter Hakari.
* BenevolentBoss: Hahari is shown to be very considerate of her maid Mei, as Mei is one of the few people Hahari displays any restraint towards, and she frequently shows concern for Mei's well-being.
* CameraFiend: Will unabashedly take photos of anyone in the harem acting or looking cute, [[StalkerWithACrush whether they're aware of her being there or not.]]
* CloudcuckoolandersMinder: To Mei. While [[LovableSexManiac Hahari herself]] is the ''[[DepravedBisexual furthest]]'' [[ComedicLolicon thing]] from a StraightMan, even she thinks the level of Mei’s devotion to her is insane and has to tone down her rigid sense of duty before she goes too far in carrying out her orders.
* ComedicLolicon: Has been {{Flanderized}} into this, with her actions (especially involving Kurumi, as well as during the hair chapter) crossing the line from funny to creepy.
* CommonalityConnection: Turns out Rentarou is not the only one to have more than one soulmate. The difference is that her previous lover is long dead, but it does mean that he can understand how she feels when she worries that dating Rentarou would betray her earlier boyfriend’s memory.
* CutenessOverload: She absolutely adores cute things, including but not limited to her soulmates and the shorter members of the family; when she first saw Mei, who was collapsed on the street in the snow, she decided to help because she thought she was just too cute.
* DeconstructedCharacterArchetype: Of the AbsurdlyYouthfulMother. To begin with, she's only as attractive as she is because she gave birth at a ridiculously young age, having impulsively decided to get pregnant before her terminally ill boyfriend died. Though she loves her daughter, she made immense sacrifices as a result and is paranoid that Hakari will get pregnant and throw her life away as well, leading to her imprisoning her child in her own home and threatening to kill her boyfriend. Then, the instant she meets said boyfriend, she loses it and proposes to him immediately, despite him being, you know, ''her daughter’s boyfriend'', and ''a teenager''. Even a decade and a half later, she still has no self-restraint and can’t stop pining over her dead boyfriend. Her character arc basically shows how psychologically damaged a MILF would have to be to actually reciprocate the fantasies of a teenage boy.
* DepravedBisexual: PlayedForLaughs because there is always someone to stop her before she goes too far, but she spends most of her time after joining the harem gushing over how cute Rentarou and the girls are. She frequently tries to start activities meant to emphasize that cuteness, and some of them are far too erotic for the girls to accept. Chapter 42 downright states her most basic desire is to grab and stroke anything cute, which of course includes the girls of the harem.
* EasilyForgiven: Once she becomes a soulmate, no one brings up her deplorable prior actions ever again, and as her character is developed they seem [[CharacterizationMarchesOn more and more out of character]].
* EveryoneHasStandards: Generally whenever she ponders and tries drawing a moral line, the girls are quick to call her a hypocrite. Nonetheless...
** Hahari for all her DepravedBisexual tendencies has never so much as asked for a kiss from Mei, because knowing full well Mei would literally do anything she asks, Hahari saw it as an abuse of power. Once she does, she asks specifically as Mei's friend and not her master.
** Even with [[ItMakesSenseInContext her drugged-up hair]] [[NaughtyTentacles playing tentacle with everything in range based solely on her own instincts]], the extras show that they only tickled [[PurityPersonified Mei and Shizuka.]]
** She also makes clear that Rentarou should ask Chiyo's parents permission before dating her at least, and when Rentarou informs her that her father is the one who set them up in the first place, she calls him out.
** After smacking Iku's behind once, she makes sure to ask permission before continuing.
** She expresses concern about Hakari's grades slipping if Hakari keeps getting caught up in delusions about Rentarou.
** After discovering Yaku's older than her, she's extremely embarrassed about having gone all CutenessOverload towards her, thinking she was a little girl.
* {{Fiction 500}}: Her house is enormous, the hallways have a laser security system to ward off intruders, she was able to get IVF treatment as a teenager, and she employs a legion of housekeepers who are trained to attack any boyfriend her daughter brings home. Once she joins the harem, she buys out their high school to become the “chairwoman” so as to spend time with him, despite having no teaching credentials. She lampshades this in Chapter 58 when asked how she managed to get thirteen outfits done for Rentarou's family overnight: "The power of capital is enough to make any ridiculous demand a trivial matter".
** In chapter 79, her parents are mentioned to have managed a company that sponsored a popular kids show when she was young, holding enough sway over said show that [[spoiler:the toys started having closed mouths due to Hahari French kissing her dolls]].
* FlowersOfFemininity: Like her daughter. Only they're ''all over'' her hair.
* TheFriendNobodyLikes: Apart from [[ExtremeDoormat Mei]], pretty much none of Rentarou's other girlfriends really respect her (despite all the authority she bought herself into at their school), and even her own daughter tends to be at most exasperatedly tolerant. Kurumi is particularly prone to putting her down whenever she gets handsy. Even ''[[NiceGirl Shizuka]]'' has snarked at her expense a few times.
* FriendlessBackground: After her boyfriend died, she refused to date anyone else out of fear of disrespecting his memory. For the next decade and a half, her only company was her daughter, her maids, and the mansion's guards.
* GagBoobs: Her boobs are so big that when she trips and falls while baserunning in Chapter 36, her boobs are able to touch the base and get her called safe, despite neither of her hands touching it.
* {{Gainaxing}}: When pitching a baseball, there is a closeup on her boobs, complete with a "BOING!" sound effect.
* GirlOnGirlIsHot: Gets a {{Nosebleed}} watching her daughter making out with Karane.
* GirlsLoveStuffedAnimals: She goes gooey over the Teddy Babies in Chapter 79, and is excited at the prospect of winning one in a quiz.
* HeroicBSOD: Temporarily isolates herself in her bedroom after her MyGodWhatHaveIDone reaction to covering the whole world in her hair.
* HypocriticalHumor: A good chunk of the jokes surrounding her are of this flavor.
* KarmaHoudiniWarranty: Brought up in Chapter 55, where Toruru points out that if word of her perverted behavior went public, she - and the people she pervs on, who are students at her school - would face serious consequences in society.
* KnightTemplarParent: Her daughter has a boyfriend, so what does she do? Imprison said daughter in her own home and ''try to kill the boyfriend''. Granted, this was also after finding out that her daughter had become part of a polyamorous harem, but straight-up murder is going too far.
* LikeMotherLikeDaughter: Her personal story shows she's as driven by her feelings as Hakari is (one of the reasons she does not approve of Rentarou at the beginning). Her fear of having her beloved daughter suffer the same things she suffered at her age explains a lot of her initial attitude.
* LovableSexManiac: She openly lusts after the other girlfriends, including her own daughter, nearly, if not more, than she does for Rentarou. The girls are very annoyed, but they mostly tolerate it because they know she means no harm. Some of her antics include:
** Convincing all the girls except Shizuka to peep on Rentarou while he's taking a bath (with the express purpose of seeing his peepee, as Kusuri delicately puts it).
** And then, crossdressing Rentarou and Nano just to enjoy the view and die of cuteness.
** Sneaking underneath Iku's hospital bed to take cute photos of her while asleep. [[WhatTheHellHero Kurumi is not amused.]]
* LoveFreak: Of the "I'm everyone's mommy" variety. A rather comically depraved variety.
* MaidCorps: She has numerous maids working in her mansion, two of whom are among Rentarou's soulmates.
* MeaningfulName: Hahari contains "Haha", the Japanese word for Mother.
* MrsRobinson: She absolutely adores cute things, like younger men... and Rentarou-chan and Rentarou-chan and Rentarou-chan...
* TheMourningAfter: Downplayed, as she does become one of Rentaro's girlfriends, but even so she feels guilty about betraying her first boyfriend's memory.
* MumLooksLikeASister: She doesn’t look much different than her daughter, especially during closeups.
* MyGodWhatHaveIDone: Does not take being responsible for covering the entire planet with living hair as a result of her impulsiveness well, to the extent that she locks herself in her room the day after. It takes Rentarou showing her that her hair didn't hurt anyone and that she [[ItMakesSenseInContext averted an early Ice Age by refueling the Sun with her hair, saving the planet]], to bring her out.
* NoHeroToHisValet: Sure, Mei adores her,[[note]]this is not an {{Inversion}} because Administrivia/TropesAreFlexible[[/note]] but her daughter Hakari often finds her behaviors bizarre and disappointing, though she learns to appreciate her more after the girls are accidentally turned into babies.
* NoseBleed: Experiences a pretty severe one while watching the cross-dressing fashion show Rentarou puts on for her. She experiences another while eavesdropping on Hakari and Karane when the latter two are in the bath.
* NotWithThemForTheMoney: On the receiving end of this with Hakari's father and Rentarou.
* OjouRinglets: Sometimes wears the full twin-set at home, though at school she usually opts for [[FashionableAsymmetry only one on the side]], and the rest tied back in a PrimAndProperBun.
* OlderThanTheyLook: At least in a school girl outfit, Hahari can pass off as a third-year student to onlookers. She's basically Hakari but with longer hair.
* ParentalIncest: Hakari is not exempt from Hahari's sexual perversions, and it's not anything new; as revealed in Chapter 44, she would often kiss Hakari when she was small, through her daughter doesn't remember it. Ironically enough, it happens again in the present, and she still isn't aware of it, [[ItMakesJustAsMuchSenseInContext as Hakari was asleep thanks to Kusuri's sleeping drug and Hahari, was blindfolded]]. The narrator has to tell the reader what happened because none of the characters know.
* ThePiratesWhoDontDoAnything: After she assumes the position of chairwoman, she is rarely seen running the school, just hanging out with Rentarou and the girls at recess.
* PsychopathicWomanchild: She is, quite possibly, ''the'' most messed-up character in the whole series, whether as KnightTemplarParent or DepravedBisexual. Nano comments at one point that it's hard to say her development since her intro has been an improvement.
* ShipperOnDeck: While she mostly wants to get intimate with them herself, she also enjoys any of the girls being intimate with either Rentarou or each other. Her biggest ship by far is Hakari and Karane; she nearly died of a nose bleed after spying the two bathing together, though admittedly the two were [[SkinshipGrope borderline having sex at the time.]]
* StepfordSmiler: Never got over the death of her boyfriend from middle school, and absolutely cannot handle romantic love.
* StrongFamilyResemblance: Flashbacks show her to have looked exactly like Hakari when she was that age, except for the long hair.
* StrugglingSingleMother: Hahari loves her daughter deeply, but she made it clear that raising her without Hakari's father was incredibly hard. She never wanted for money, but she describes it as a task that required her complete devotion and strength.
* TeenPregnancy: She gave birth to Hakari when she was 13 years old.
* TrademarkFavoriteFood: Shark fins.
* UnlimitedWardrobe: Hahari loves dress-up and has a gigantic closet filled with everything from costumes to baby clothes. If she doesn't have something specific, she'll pay for them to be tailored overnight.
* UnusuallyUninterestingSight: None of the girls to join the harem after her find it at all strange that she, an adult woman, is one of Rentarou's girlfriends (among whom is her ''daughter.'')
* WhatYouAreInTheDark: Shown in her first meeting with Mei. She didn't ''have'' to run outside and help a bedraggled, half-frozen urchin, but she did anyway. (Admittedly, it was because she thought Mei was too cute more than anything else, but still, she ''did'' help her.)

[[folder:Kurumi Haraga]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/kurumi_haraga.png]]
[[caption-width-right:350:The BigEater]]
A middle school student who is hungry all the time, and the 7th girlfriend, who unfortunately lashes out at people due to hunger.
----
* BigEater: Gets hungry very quickly, and her unusually fast metabolism is the only reason why she isn’t obese. (Although, not even Kurumi is immune from feeling sick if she eats ''far'' too much at once.)
* CuteLittleFangs: Possesses a little fang in her mouth.
* DeadpanSnarker: Shares this role with Karane.
* DeconstructedCharacterArchetype: She’s a BigEater because of a medical condition, which makes her obsessed with food to the point that it interferes with her day-to-day life.
* DefrostingIceQueen: To Rentarou at first, though mainly because of her hunger issues. She was also this to the harem, stating upfront that she only intended to be close to Rentarou. Her attitude changed after the eating contest, and she later on admits that she enjoys spending time with them.
* DoesNotLikeSpam: [[{{Irony}} Walnuts]]. She doesn't ''hate'' them, but she's been long sick of eating them every time she heard her own name, which is Japanese for "walnut".
* ExtremeOmnivore: She will even bite into inanimate objects if they remind her of food shaped like the aforementioned objects. She doesn't succeed in swallowing them, though.
* FatalFlaw: Gluttony. She'll even try to eat a baseball because it reminds her of candy.
* {{Foil}}:
** She and Hakari are both slaves to their passions. However, Kurumi doesn't like her food obsession but can do nothing to stop it.
** Like Karane, she's a tsundere. However, whereas Karane is a "traditional" tsundere, Kurumi has no control over when she's nice and when she's mean. She acts like a bitch when she's hungry and is nice otherwise.
* FoodAsBribe: A frequent victim of this trope, befitting her BigEater status.
* HeadphonesEqualIsolation: She wears big headphones and a hood to avoid hearing or seeing anything that would trigger her food obsession.
* HeroicSelfDeprecation: Since she’s not herself when she’s hungry (which is all the time) and pushes people away, as a result, she thinks she has zero redeeming qualities.
* HonorBeforeReason: When she reveals that she developed a craving for a french kiss in Chapter 44, she admits that she'd rather suffer with the craving than ask Rentarou for one because 1) none of his other girlfriends have gotten one and she refuses to get special treatment, and 2) Rentarou giving all of his girlfriends french kisses wouldn't be family-friendly.
* HyperactiveMetabolism: Gets hungry again quickly even after she's finished eating.
* InTheHood: She's only seen without her hood on when she's not wearing her jacket in the first place.
* InstantTasteAddiction: Exaggerated. She will start craving a food whenever she sees or hears anything that bears the slightest resemblance to it or its name.
* IronicName: A rare justified example: Kurumi means "walnut", and walnuts are the one food that she ''doesn't'' like... because her food obsession used to trigger so often from hearing her own name that she's sick of them.
* UsefulNotes/JapaneseHonorifics: Does ''not'' like being addressed as “-chan”, which Rentarou notes is a first for the girls.
* JekyllAndHyde: Usually a sweet girl, but once she becomes hungry, she becomes aggressive until her hunger is satisfied; she's practically a [[VideoGame/PokemonSwordAndShield Morpeko]] in human form.
* JerkassHasAPoint: Though she does yell too much when they first meet, the fact that a high school boy is taking such an interest in her when she’s in middle school would in fact be perceived as stalkerish [[FourthWallMyopia to someone unaware of the soulmates thing]], so it’s understandable that she constantly tells him to scram.
* LittleMissSnarker: Frequently mentions that the group is abnormal, and is one of the younger members of the group.
* MeaningfulName: Her last name is a pun on a phrase meaning "I am hungry", and is considered a somewhat rude one at that.
* NightmareFace: The expressions she makes when she's hungry can be rather [[DeathGlare unnerving.]]
* ObsessedWithFood: Pretty much anything can remind her of food.
* OneTrackMindedHunger: When hungry (which is almost always), she will become aggressive and can't help but think about the food she wants.
* OnlySaneMan: Whenever the subject is not food, she will [[LittleMissSnarker point out how insane the rest of the girls' eccentricities are]].
* OOCIsSeriousBusiness: To sell how she's desperate she is to relieve her french kiss craving, she admits that she would let Hahari be the one to do it if it meant her suffering would be relieved a little.
* OrgasmicallyDelicious: Her reaction when she gets to eat what she's craving.
* OutsideContextProblem: While she was able to control her cravings with food before, Chapter 44 has her deal with a craving for a french kiss after watching a movie one day.
* PickyEater: Downplayed. Once she starts thinking about a particular food, nothing else will satisfy her craving no matter how similar it is.
* SempaiKouhai: The ''kouhai'' to most of the cast. It even annoys her that she has the urge to pat Shizuka on the head.
* StraightMan: She considers herself second to Karane in this department.
* {{Tsundere}}: Though she's less of a parody than Karane. She's grumpy and hostile to everyone when she's hungry, but apologetic and demure when fed. She's also more upfront (albeit reluctant) about her feelings than Karane. According to Kusuri, her disposition is the result of the "hangry factor".
* WhatBeautifulEyes: Kurumi has striking eyes that are shaped differently than everyone else's, and Rentarou finds them beautiful.
* WingdingEyes: Her eyes turn into four-point stars when she's enjoying food.

[[folder:Mei Meido]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/meido01_eyeclosed_2.png]]
[[caption-width-right:350:The [[HyperCompetentSidekick Hyper-competent]] {{Maid}}. [[labelnote: Click here to see her eyes]] https://static.tvtropes.org/pmwiki/pub/images/0030_017.png[[/labelnote]]]]
Hahari's trusty maid, who becomes the 8th girlfriend after Rentarou gets her to open her [[EyesAlwaysShut always-shut eyes]].
----
* AllThereInTheManual: Her first meeting with Hahari, and the outline of her background, are covered in volume 4's bonus story. Her background was cut from the main manga for being so heart-rending it clashed too heavily with the tone.
* AmbiguouslyBi: Is obviously attracted to Rentarou, but is also so devoted to Hahari that it practically crosses the line into HomoeroticSubtext. The clothing she and Rentarou were picking out as a gift for Hahari made them both gasp at the thought of her wearing them. Even her compliance to (attempt to) kiss Hahari is based on her asking.
* AnimalMotifs: Mei is repeatedly compared to a dog, with how eagerly and excitedly she obeys her master's commands. She even gains ears and a wagging tail at times. Rentarou isn't too thrilled to make the comparison when she brings a cherry blossom branch to him at his request.
* BerserkButton: If you intend to cause Hahari harm in any fashion, you'd better hope she doesn't grant Mei permission to retaliate.
* BewareTheNiceOnes: Submissive to her masters she may be, but she doesn't take kindly to underlings who cause trouble for the people she knows.
* BlindDriving: She can drive a car ''while completely blind''. And then she repeats the stunt with ''[[ExaggeratedTrope a helicopter]]''.
* BrokenAce: She's ridiculously good at anything that's feasibly possible and isn't social, by virtue of being practically blind. Driving, water gun fights, trimming Mimimi's hair, etc. Unfortunately she's lacking in common sense and self-worth.
* CatchPhrase:
** "Understood."
** "If I may be so bold."
* ChekhovsGunman: She was a LivingProp for several chapters after Hahari joined the harem, before receiving ADayInTheLimelight culminating in her becoming one of the girlfriends too.
* DeconstructedCharacterArchetype: Mei embodies the fantasy of the servant who is utterly devoted to their master, who will obey their every command, who absolutely lives to serve... and as a result, she has nothing she lives for ''outside'' of her masters, not even herself. It turns out this is because she didn't value her life in the first place, her abusive childhood having effectively obliterated it.
* DeniedFoodAsPunishment: Implied. She mentions in chapter 89 that the food being served as part of the training would've been a veritable feast for her before she met Hahari.
* DisabilityImmunity: Because Mei's eyes are always closed, she's completely unaffected by the "steamy-as-hell challenge ramen", which was designed to hurt a person's eyes.
* EarlyBirdCameo: Her first confirmed appearance at the end of Chapter 20,[[note]]while it isn't confirmed, it's possible that she was the maid who informed Hahari of her daughter attempting to jump out the window[[/note]] where she provides Hahari with a coil of rope as she and Hakari head off to peep on Rentarou. In the next chapter, she escorts the girls up to the attic above the bath, and in the chapter after that, she and Hahari see off Rentarou and the girls as they head home to collect their school uniforms.
* EmotionlessGirl: To the point where even [[HypocriticalHumor Nano]] comments on it. She has no thoughts or desires that don't pertain to serving her master.
* ExtremeDoormat: She never questions a single order (real or perceived) from Hahari or Rentarou, to the point where she won’t hesitate to attempt suicide if she thinks she failed either of them.
* EyesAlwaysShut: Mei has kept her eyes shut for so long she's forgotten how to open them. Not being able to see, she relies on her other senses instead.
* {{Foil}}: To several of the other girlfriends.
** Mei is emotionless due to constantly smiling, while Nano is emotionless due to never smiling.
** Mei is willing to hurt herself if it means obeying what she thinks are orders from her master, while Iku is willing to hurt herself purely for pleasure.
** Mei is completely obedient to Hahari (and later Rentarou) to a fault, while Naddy doesn't hesitate to assert herself against Hahari despite the latter being the former's boss.
** Mei is older, a flawless maid, and devoted to her masters. Mai is younger, a {{cute clumsy|girl}} {{maid}}, and devoted to Mei especially. Mei's devotion compels her to go above and beyond in the name of duty, while Mai's devotion distracts her from her duty. Mei is an ExtremeDoormat, while Mai knows full well what she wants, and takes action to get it.
** Mei and Momoha were kicked out of their family's homes and eventually found by Hahari, and they both do work for her in exchange for living where they work. But while Mei's parents disowned her due to being crippled by loan shark debts, Momoha was disowned because her parents thought she was doing too much for them.
* GratuitousFrench: The song she sings at the karaoke bar has French lyrics.
* GrewASpine: Downplayed. Her second {{Catchphrase}} "If I may be so bold" is first spoken in chapter 54. It's a sign that she's learning to be more assertive.
* HandicappedBadass: Mei might effectively be blind, but her other senses are so sharp that she can do anything a person with sight can do, and she's consistently portrayed as one of the most competent members of the family.
* HappinessInSlavery: [[DownplayedTrope Not quite slavery]], but she turned down an offer to be adopted into the Hanazono family in favor of working as a live-in maid.
* ImprobablePilotingSkills: Can fly a helicopter while blind.
* LoveAtFirstSight: Literally. While all the girls start falling for Rentarou this way, Mei is introduced to him several chapters before she's revealed as one of his soulmates when she makes [[EyesAlwaysShut actual eye contact]] with him.
* {{Maid}}: Of course!
* MajorInjuryUnderreaction: She never reacts to any kind of injuries (real or fake) more strongly than in a calm manner.
* NightmareFace: As her eyes-open portrait demonstrates. While her eyes are ''[[TakeOurWordForIt supposedly]]'' lovely rainbow-like things, that can't really come across in a black-and-white medium. Combine that with the fact that she can only open those bright eyes when she’s [[OhCrap shocked]] or [[GameFace about to wipe the floor with you]]...
* NinjaMaid: She is unexpectedly agile in her maid uniform, to Karane's shock when she effortlessly dodges out of the way of her squirt gun. She's ultimately the last one standing in that game, only to be disqualified on a technicality. (Not that it matters, because Rentarou kisses everyone anyway as a reward.)
* OhCrap: Invoked by Rentarou. Realizing the humiliating story he told her was about Hahari and not Rentarou is what finally causes her to open those bright eyes. Afterward, it's notable that the only time her eyes open is when she's having a moment like this.
* OOCIsSeriousBusiness: She has also been seen with open eyes when she's donning a GameFace.
* ParentalAbandonment: Mei reveals in volume 4's bonus story that her parents, who were deep in debt to loan sharks, [[AbusiveParents abused her]], then eventually abandoned her to make her own way on the streets. By the time Hahari first met her, she already put little to no value on her life.
* PerpetualSmiler: Believes a maid should never stop smiling in front of her master. For some reason, this includes having her eyes closed, too.
* PhraseCatcher: "That wasn't an order!"
* RecruitedFromTheGutter: After Hahari learned Mei had been abandoned to wander the streets by her AbusiveParents, she and Hakari offered to adopt her as part of the family. Mei couldn't accept that, so she instead agreed to become a live-in maid.
* SatelliteCharacter: Deconstructed. Mei is so devoted towards Hahari and Rentarou that making her own decisions is alien to her, and sees no value in taking care of her self. Rentarou and Hahari make efforts to break her from this.
* StevenUlyssesPerhero: Her family name is Meido, and she's a maid (though they're not written the same way in Japanese).
* SuicideAsComedy: Has a bad habit of offering to kill herself if she makes a mistake while serving her mistress. Hahari is very fast to talk her out of it.
* SuperSenses: Due to having her EyesAlwaysShut, blindfolds and blinding attacks have no effect on her, and her other senses are heightened to ludicrous levels.
* SurprisinglyRealisticOutcome: Normally a character with EyesAlwaysShut is just a design choice and they can see perfectly fine. Mei is actually blind because her eyes are always closed.
* TechnicolorEyes: Mei has hypnotic, rainbow-colored eyes.
* UndyingLoyalty: Mei takes this to an extreme; she has no interests outside of serving her masters (Hahari and Rentarou), and she will obey any order given to her no matter how dangerous it may be to her health. She sees no value in taking care of herself because all she values are being of use and worth to her masters. Rentarou gets her to realize that her mere existence is valuable to him.
** She has also believed Kurumi to be giving her orders on occasion.
* WhatBeautifulEyes: Her eyes are ''rainbow-colored'', which Hahari comments on. Too bad that she rarely opens them.
* WholeEpisodeFlashback: Her backstory was relegated to a bonus chapter due to [[TearJerker clashing too heavily with the rest of the manga]].

[[folder:Iku Sutou]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/img_20201130_090311.jpg]]
[[caption-width-right:350:The [[PassionateSportsGirl Sporty]] [[TooKinkyToTorture Masochist]]]]
The 9th girlfriend. She is the only available member of the Girls' Baseball Club, and a major masochist.
----
* {{Bokukko}}: Uses the ''[[UsefulNotes/JapanesePronouns boku]]'' pronoun, and Rentarou mentions her "boyish charm".
* BoyishShortHair: Iku has short neck-length hair, befitting her status as a tomboy.
* {{Catchphrase}}: “It hurts…!❤️”
* CharacterTics: She has a habit of scratching her cheek when embarrassed.
* ClarkKentOutfit: She's not overly buff and appears to have the average muscle build of a teenage girl, but she has a toned figure underneath her outfit.
* ADayInTheLimelight: Shares one with Mei in Chapter 89, which sees the two of them embark on intense ascetic training.
* DeconstructedCharacterArchetype: Somehow, "[[PassionateSportsGirl sporty girl enthusiastic about her dying club]]" becomes "masochist obsessed with TrainingFromHell", determination getting exaggerated into masochism, then looping back round into determination again. She's so determined to train she collapses due to spending all night swinging, not even her masochism enough to keep her going.
* {{Determinator}}:
** Trains overnight to the point she collapses, in response to how Rentarou and the others helped her.
** Also parodied: at one point, she declares "If there's something I can't do, then that just means I wasn't trying hard enough!", which is fairly standard determinator-speak... except she's talking about filling in for an entire baseball team by herself.
* DidntThinkThisThrough: The reason why her club is about to be disbanded is that the other members went to America to study, with only her behind. Rentarou even calls this surpassing tunnel vision.
* {{Foil}}: Iku endures pain out of pure enjoyment, while Mei endures pain if she thinks it's her master's request.
* GoneHorriblyRight: When she was much younger, Iku was a crybaby who would give up on something once it got too tough. Her older brother tried to correct this once she started getting into baseball by telling her that she had to keep at something to improve at it, [[{{Determinator}} even if it hurt.]] Unfortunately, Iku came to the conclusion that "if powering through pain = getting better, [[ComicallyMissingThePoint then pain = a good thing]]", which awakened her masochism.
* HeroicRROD:
** Spends all night practicing her swing, then immediately passes out once she meets Rentarou and the girls the next day.
** [[PlayedForLaughs More comedically]], it's later revealed that she does this to herself on purpose so that her muscles are in a constant state of pain. When Momiji forces her into a massage to alleviate it, Iku starts ''crying in remorse.'' The effect is compared to a case of ReviveKillsZombie.
* IAmNotPretty: Downplayed; she thinks she looks plain compared to the rest of the harem, consisting of beautiful women and cute girls.
* IronicName: "Sutou Iku" is a pun on "[[GratuitousEnglish stoic]]". She is anything but.
* LoudGulp: A frequent reaction to seeing something that could be painful.
* MadnessMantra: Tries to sneak out of the infirmary after passing out from exhaustion, still saying, "Practice... gotta train..."
* ReviveKillsZombie: One of the few things that can upset her is when Momiji massages away her carefully cultivated muscle pain.
* TomboyWithAGirlyStreak: She's as tomboyish as they come, but is perfectly happy to wear a skirt for her movie date with Rentarou.
* TooKinkyToTorture: She's a masochist that gets off to pain, physical or emotional. Even getting her ''heart broken.''
** According to Momiji, Iku's always in extreme pain due to her workouts causing muscle damage, to the point that Momiji wonders how Iku is able to even walk let alone act normal.
** She also deliberately messes up her concentration in chapter 89 so that the machine monitoring her keeps smacking her. The ReadingsAreOffTheScale when the monk overseeing the training returns.
* TraumaButton: She once hit a homerun that injured a girl in the audience, and since then standing in the batter's box causes the memory to resurface, and she freezes.
* {{Understatement}}: Says she is going to get in a little more practice after everyone leaves... and when they all return to school the next morning, she's done ''more than 100,000 practice swings'', having been there all night without a break. To her, this is perfectly normal.[[note]]And since there are only 86,400 seconds in a day, and she was only there for about eight hours, she must have managed to do about four or five swings per second! Of course, that's assuming her counting wasn't thrown out of whack during that time.[[/note]]
* VerbalTic: Parodied. Her dialogue balloons have heart symbols when she's experiencing pain.
* WhenSheSmiles: Chapter 36 ends with her giving a huge smile after hitting a walk-off grand slam and kissing Rentarou after he caught it, telling him she loves him.
* WholeEpisodeFlashback: Volume 5's bonus chapter is Iku's older brother Ikuya explaining how she became a masochist.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/screenshot_2020_11_30_08_57_47_92.jpg]]
[[caption-width-right:350:The {{Narcissist}}]]
The 10th girlfriend. She is Rentarou's upperclassman by one grade and is obsessed with looking beautiful.
----
* AttentionWhore: She absolutely adores being the center of attention, even using this desire to distract a CameraFiend trying to snap photos of Meme.
* {{Catchphrase}}: "Naturally." In Japanese, it's "Ustukushi", which is part of her surname.
* ComicallyMissingThePoint: When Meme mentions wishing she could be more like Mimimi, the latter thinks Meme wants to look as beautiful as her, even though Meme was actually talking about having confidence in herself.
* DeconstructedCharacterArchetype: Of the {{narcissist}} obsessed with their own beauty. As far as she's concerned, beauty can't simply be bought, it has to be worked for as well, and she puts a lot of work into making herself beautiful, earning her own money, cutting costs wherever she can, doing facial regimens, and teaching herself elocution.
* EndearinglyDorky: Mimimi puts on an air of sophistication as another layer of beauty. While she ''can'' be genuinely dignified at times, her blatant attempts to stay that way and inability to act modest towards compliments (imagined or not) make her appear more "cute" than just beautiful. Rentarou lampshades as much about the latter on their first date.
* TheFashionista: Takes pride in dressing well and dresses up Rentarou in her style.
* {{Foil}}: To Meme. Mimimi constantly works towards being beautiful, while Meme tries to make herself stand out less. Mimimi loves being noticed and admired, while even ''slight'' attention being thrown her way causes Meme to make herself disappear.
* ForeheadOfDoom: Mimimi's hairstyle shows off her prominent forehead, which has at least once been used to pull off the classic BlindedByTheLight gag
* GoshDangItToHeck: She never uses any profanity, no matter how mild.
* HairOfGoldHeartOfGold: Mimimi's official hair color is blonde, and in a departure to the usual {{Narcissist}} she values ''inner beauty'' the most and is supportive towards others. At worst she's just condescending without actually being malicious.
* HiddenDepths:
** She believes that beauty isn't simply bestowed and it has to be created through continuous effort and earns her own money in order to do so. When a guy jeers at her, she ignores it, telling Rentarou that being envied is a consequence beautiful people must accept. She also views beauty as involving more than just external appearances, seeing Rentarou as having a beautiful heart.
** Besides her beauty, her part-time job as a newspaper courier makes her a VERY fast runner.
* HoistByHerOwnPetard: Her skin is so smooth that Rentarou is unable to maintain a firm grip on her during the sumo tournament. But it also makes it harder for her to stand barefoot, causing her to lose.
* LargeHam: She's nothing if not flowery in her mannerisms.
* MeaningfulName: Mimimi is "beautiful" repeated three times, and Utsukushisugi means "extremely beautiful".
* {{Narcissist}}: Lampshaded by Rentarou. To the point where she expresses envy towards him for dating ''her'' when they just met. Although she does love Rentarou for his inner beauty.
* NonUniformUniform: She pretty much doesn't wear the uniform at all, instead wearing a bodice over her top and fancy stockings and boots below her skirt. Yet she still designs something completely different when Naddy has the girls dress the way they always wanted to instead of what the school demands of them.[[note]]Given that her "freedom outfit" was three times as tall as herself, it's understandable that her normal outfit is what it is.[[/note]]
* NotGoodWithRejection: Downplayed. Nano coldly rejecting her hand at friendship made her sensitive to it, which she admits is what made her act oblivious to Rentarou questioning her upfront proposal to be his girlfriend.
* ThePratfall: Her skin is so smooth that if she takes her shoes off and the ground under her is smooth, she risks slipping and falling.
* ProudBeauty: ''Very'' much so, though it's made clear in her introduction chapter that she's proud because she puts so much work into being beautiful.
* PunnyName: To English speakers, Mimimi [[LuckyTranslation happens to sound like]] "Me, me, me!" which plays into how she comes across as a vain narcissist.
* TheRival: To Nano. In the past Nano had bested Mimimi in a beauty pageant (Which Mimimi orchestrated for Nano to sign up for in the first place) and [[GracefulLoser when Mimimi offered a hand in friendship]] Nano, already deep into being an emotionless logic-driven being, snubbed her. This caused resentment in Mimimi in the present and she challenges Nano to a beauty contest for Rentarou's affections.
* StatuesqueStunner: She has a few inches over Rentarou and the rest of the girls (Aside from [[BigBeautifulWoman Yamame]]).
* StepfordSmiler: Parodied. When put in less-than-comfortable situations, like getting cramped in a photo booth with several people or in the middle of a storm, she just smiles to endure.
* StraightMan: Zig-Zagged. On occasion she snarks at the series’ weirdness, though her own narcissism tends to mess it up half the time.
* VerbalTic: Tends to say "naturally" and "of course" a lot, especially when explaining something or receiving (what she thinks is) a compliment.
* WorkplaceAcquiredAbilities: Uses her beautician skills ([[ImprobableWeaponUser and a hair brush]]) to parry Hahari's attacking hair.

[[folder:Hakari Hanazono]]
-->'''Voiced by:''' Creator/ReinaUeda (voice drama)
[[quoteright:275:https://static.tvtropes.org/pmwiki/pub/images/hakari_hanazono_color.png]]
[[caption-width-right:275:The LoveFreak [[FirstGirlWins First Girl]]]]
One of the two first girlfriends together with Karane. The daughter of a wealthy family is absolutely infatuated with Rentarou and wastes no chance to show it to him. Or to seduce him, for that matter.
----
* BigBreastPride: ''Very'' proud. When Rentarou asks around about Meme, Hakari asserts her estimation that Meme is around her own bust size while taunting [[ACupAngst Karane]] over it. Which makes it [[BreakTheHaughty a bitter pill to swallow]] when it turns out Meme is [[HiddenBuxom even]] ''[[HiddenBuxom larger]]''.
* CovertPervert: Likes to show a prim and proper image, but in private, she's very physical in her affection and not ashamed of it. Another notable trait [[GenerationXerox inherited from her mother]]. The covert part is almost non-existent later in the series, as her perverted habits become well known among everyone.
* ADateWithRosiePalms: Possibly referenced. It's repeatedly shown that Hakari's body is... unusually sensitive, which the volume 5 extras attribute to her "[[UnusualEuphemism daily pursuit of knowledge]]".
* ADayInTheLimelight:
** After debuting in Chapter 1, she gets more attention in Chapters 15 and 16, when her mother holds her prisoner in their home until the conflict is resolved.
** Chapter 103 has Hakari's desires in overdrive after watching a movie with a racy scene in it, and she spends the entire chapter trying to find ways around Rentarou's CelibateHero mindset.
* DeadpanSnarker: At either Karane or Hahari’s expense. Sometimes insincerely, sometimes blunt like a bat (mostly Hahari.)
* DeconstructedCharacterArchetype: Being closer to Rentarou on their CrashIntoHello, she is technically the First Girl, and unlike how the first girl tends to be an overly perfect person with little personality, Hakari is [[BeAWhoreToGetYourMan one of the most aggressively sexual]] and devious girls, possibly because she wants to cement her "claim" ahead of the others. At the same time, she's ruled by her feelings to the point that she doesn’t understand them, and [[GenerationXerox her mother couldn’t help her with that]].
* DisappearedDad: Her father died from a terminal illness shortly before she was born.
* DrivenToSuicide: Is willing to jump to her death if she can never see Rentarou again. Fortunately, it doesn’t come to that.
* EstablishingCharacterMoment: The reason she and Karane are introduced at the same time is to make it clear that most of the annoying harem cliches will be averted, as they both accept the idea of sharing Rentarou instantly, as well as letting other girls in.
* EveryoneHasStandards: Hakari is a shameless pervert when it comes to Rentarou, but she does have her limits.
** She's horrified upon seeing an ImagineSpot with Chiyo tied up, stating that showing a young girl in such a position isn't legal.
** She's frequently disgusted by her mother's even more perverted antics.
* FailureIsTheOnlyOption: Played With. Rentarou [[LoveFreak being who he is]], he’s affectionate towards Hakari either way. But any attempts she makes to seduce him or just get his attention on her own terms are always doomed to fail. Typically because Rentarou is too clever or too pure to fall for her tricks. She’s fully aware that the manga itself would never allow her to win, to the point where she [[spoiler: hallucinates beating him in a sumo match and stripping naked to glomp him.]]
* {{Foil}}:
** She's all feelings, in contrast to Nano’s rational viewpoint.
** Her tender attitude and cunning nature is a contrast to Karane's rudeness and bashful dishonesty.
** While Hakari and Hahari are both lustful, Hakari is comparatively more restrained in who she targets, how many she targets, and what she'll do to them, and takes a dim view of her mother's childish behavior.
* ForgottenFirstMeeting: She and her mother met a kindergarten-age Momiji at a moon-bounce, and cemented Momiji's love of touching soft things.
* GagBoobs: Quite a few of the jokes in the [[BreatherEpisode breather chapters]] relate to the size of her chest.
* HeroicBastard: It's never commented or brought up after Hahari's appearance and past, but Hakari's parents were ''never'' married despite being in love. {{Justified|Trope}} since Hahari and "Father-in-law" were only ''13''[[note]]Meaning they can't legally wed, as the legal marriage age in Japan for a male and female has to be 18 and 16 respectively.[[/note]], with the latter dying from a terminal illness and the former going through an impulsive decision of getting an IVF so they could be a family after his death.
* LivingEmotionalCrutch:
** Rentarou is this for her as a result of her own deep infatuation and being tied to him as his soulmate. When her mother intends to separate them, Hakari is more than willing to end her life there.
** She was this to her mother Hahari, as the latter's existence saved her from the despair after the death of her father.
* LoveFreak: Not as bad as Rentarou (Which says nothing at all, it's a high bar), but it seems that ''anything'' he does will make her swoon over him no matter how over the top.
* MadeOfIron: Or at least has a high pain tolerance. She is only slightly injured from getting hit square in the chest with a baseball, and recovers in seconds, despite it going fast and despite getting hit in the chest being almost as painful for girls as [[GroinAttack getting hit in the balls]] is for guys.
* ManipulativeBitch: Is not above manipulating people to get what she wants.
* MeaningfulName: "Hakari" is pronounced the same as the Japanese word for calculating or scheming, alluding to her manipulative tendencies.
* MsFanservice: The first one; she does not hesitate to use her assets to conquer Rentarou.
* RoseHairedSweetie: She has pink hair with flower decorations on it and is genuinely sweet to Rentarou and the other girls. [[PlayingWithATrope But uh... ]] it's more of a cultivated image that she uses to achieve her goals. She's more cunning and manipulative than the usual example.
* ParentalSexualitySquick: As alike as she and her mother are in their feelings towards Rentarou, Hakari regularly gets creeped out at Hahari's questionable fantasies towards both him and the other girlfriends.
* ShamelessFanserviceGirl: She has no issue with Rentarou (accidentally) groping her whatsoever.
* ShesGotLegs: She's got noticeably healthy thighs, something that the manga loves to emphasize. And it’s on purpose, she keeps her skirt up.
* SitcomArchnemesis: To Karane, and it’s Hakari who instigates it. She gets a kick out of poking fun at Karane’s bust size or taking advantage of her {{Tsundere}} nature to rile her up.
* SomeoneToRememberHimBy: She was conceived because Hahari wanted to have children with her dying boyfriend.
* StarCrossedLovers: Her mother subjects her to this trope when she finds out about Rentarou's other girlfriends. It doesn't last long, though.
* StealthInsult: Usually towards Karane concerning her ACupAngst, while still maintaining an innocent and dignified tone.
* {{Stripperific}}: Her idea of a "freedom outfit" is a ribbon wound around her body to hide her private parts and melted chocolate hearts painted on her bare skin.
* ThreesomeSubtext: While she is very close and friendly with the other girlfriends when it comes to her feelings for Karane, they are often shown to be just as strong and sexual in nature as her feelings for Rentarou. You can bet anytime she gets close to or kisses Rentarou she will also inevitably have a similar experience or kiss with Karane. Unlike with Rentarou though, Hakari is shown to get jealous if Karane gets close to anyone else.
* TooCleverByHalf: Rigs a [[DrawingStraws breakable chopstick]] under the assumption Nano will take the closest one on the grounds of being more efficient, only for Nano to say the most efficient course of action is to all draw at the same time.

[[folder:Karane Inda]]
-->'''Voiced by:''' Creator/HarukaShiraishi (voice drama)
[[quoteright:275:https://static.tvtropes.org/pmwiki/pub/images/karane_inda_color.png]]
[[caption-width-right:275:The {{Tsundere}}]]
One of the two first girlfriends with Hakari, a ''tsundere'' at heart due to her feelings of inadequacy but ''cannot'' deny how much she's in love with Rentarou.
----
* ActionGirl: Quite capable in a fight, easily holding the line against the leader of the Gorilla Alliance, a huge and beefy woman.
* ACupAngst: Confesses to Rentarou that she worries that he cares more for Hakari or Nano than her because she’s flat-chested and they’re stacked by comparison. Rentarou assures her that nothing of the sort is the case.
* AngerBornOfWorry: She becomes extremely livid with Hakari after the girl's near suicide attempt.
* AppearanceAngst: Actually played for drama at first. Karane is insecure enough about her own body type that she brought a raincoat to a spa. She even thinks less of herself compared to Shizuka, who has a similar build to her but believes she has a cuteness factor that she doesn't. Rentarou finds her appealing anyway, and she manages to get over it.
* AudienceSurrogate: Serves this role through her reactions to the insane events throughout the manga.
* BadLiar: She might be better at it if she didn’t constantly say something along the lines of [[{{Tsundere}} “it’s not like I did this ‘cause I care about you or anything!”]]
* BadassArmFold: Does one after taking the cape off a Gorilla Alliance member.
* BelligerentSexualTension: She and Hakari are typically at each other's throats, but are shown to be attracted to one another more than they realize or would like to admit.
* BestFriend: It's not clear if it's something she just says in the heat of the moment or not, but when faced with Ahko's old friends dismissing the way they treat her and continuing to say nasty things about her, she declares ''she's'' Ahko's BFF now, and Ahko very much appreciates it.
* BullyingADragon: Downplayed. Karane makes it clear that she doesn't just assault anybody for no good reason, and only responds to teasing with yelling. It's only when someone gets too physically touchy for her (Like MarshmallowHell for example) to tolerate that she throttles them.
* ButtMonkey: Hakari and the narrative itself ''love'' reminding Karane that she has a flat chest. And the other girlfriends' antics test her sanity and dignity every chapter.
* {{Catchphrase}}: "It's not like I'm X or anything!"
* CovertPervert: Far more covert than Hakari or her mother.
** When the decision has been made to peep on Rentarou in the bath, she immediately caves before they can even try convincing her, claiming she doesn't want to fall behind the others. [[SuspiciouslySpecificDenial And definitely not because she was interested in his body or anything.]]
** She will vehemently deny any attraction to Hakari, but then blush furiously whenever the other girl gets intimate or anywhere close to her. She also uses ACupAngst style jealousy to hide the fact she has a large breast fetish.
** When Hakari's desires are out of control, Karane explains that it happened after the two of them and Nano watched a movie with an adult scene in it. It then flashes back to Nano's perspective after said movie, [[HypocriticalHumor showing that Karane was out of commission in exactly the same way]].
* CursedWithAwesome:
** Her Tsundere-ness causes her no shortage of angst, both comical and non-comical. It's also revealed to be the source of her unusual strength and what makes up her strong will.
** She ''oh-so'' wishes she had massive breasts like Hakari or other girls who're gifted with them, but on the plus side her slim figure means she's ''far'' less likely to succumb to fatigue and cramps like them in more physically active areas, like dancing for idol practice.
* CuteLittleFangs: As befitting her tsundere nature. They’re visible whenever she’s agitated.
* DeadpanSnarker: If something out of the ordinary happens ([[WorldOfWeirdness Which is ordinary in this series]]) and Karane is there, expect her to snark at it.
* DeconstructedCharacterArchetype: Acting like a tsundere means she has difficulty expressing her feelings properly; the LieDetector is a notable example of this as she is lying not on whether or not she loves Rentarou but about how much she loves Rentarou. (She then immediately complains that the machine destroyed her self-esteem, which said machine registers as true) It also makes everyone freak out when she gets angry, as they think she’ll slap someone, despite her having more control over her emotions than that.
* DoubleStandardAbuseFemaleOnMale: Overall {{Zigzagged}}, depending on RuleOfFunny. While she has something of a HairTriggerTemper and can hit Rentarou over tiny misunderstandings, she's also quick to apologize when things are cleared up. On the other hand, one chapter casually mentions she put him in a ''[[AmusingInjuries full-body cast]]'' at least once.
* EstablishingCharacterMoment: Shares one with Hakari; their willingness to share Rentarou immediately shows that the girls aren’t gonna be jealous in this series.
* ExpressiveAccessory: Her hair ties sometimes reflect her mood, drooping when she's upset or sticking straight up when she's excited or mad.
* {{Foil}}:
** Her honesty and directness to Hakari's tenderness and habit of keeping secrets.
** Her straightforward attitude to Shizuka's shyness.
* HeroicWillpower: Or rather "Tsundere factor". Karane's physical strength is tied to her will, as the harem finds out when she takes Kusuri's Tsundere Un-maker drug. Without the parts that make her a tsundere, she's too weak to even beat Kusuri at sumo or harm Iku. Later on, Rentarou realizes that it takes every ounce of her will just to say "I love you".
* HiddenDepths: Is more well-rounded than most tsunderes. She doesn't physically attack anyone at the drop of a hat without a good reason. Furthermore, she's actually so ashamed enough of being a tsundere that she takes an "anti-tsundere" drug and protests reversing the process.
** Chapter 88 reveals that she has a talent for making cookies.
** [[{{Tsundere}} Ironically]], she's been shown to be one of the more emotionally-perceptive characters, and has repeatedly noticed when one of the other girls has been hiding their feelings about something.
* MusclesAreMeaningless: She's a slender petite young girl, and strong enough to toss people like softballs.
* OnlySaneMan: Other than Rentarou, she is most likely to object to wacky hijinks, such as when Hahari encourages the other girls to spy on Rentarou in the shower (Which she goes along with anyway).
* PunnyName: Her full name sounds like ''"Janainda kara ne"'', a very typical ''tsundere'' phrase meaning "It's not like I like you or anything!"
* StraightMan: Something that the family ''and'' manga itself lampshades and pokes fun about. Even Kurumi admits that she's second to Karane regarding this.
* StrongerThanTheyLook: [[MusclesAreMeaningless Slim as she is]], Karane's gone toe-to-toe with the Gorira Alliance's leader, nearly broken Rentarou's back with a bear hug, and sent Iku flying hundreds of feet onto a speeding car [[HomeRunHitter with a baseball bat]]. Rentarou believes her strength is tied to her force of will, seeing as she loses it after [[ItMakesSenseInContext drinking Kusuri's "tsundere unmaker" drug.]]
* SuspiciouslySpecificDenial: Karane often says, "It's not like I," before saying what she's thinking or doing, which also makes her a BadLiar.
* ThreesomeSubtext: While she is friendly with the other girlfriends when it comes to her feelings for Hakari, they are often shown to be just as strong and sexual in nature as her feelings for Rentarou. You can bet anytime she gets close to or kisses Rentarou she will also inevitably have a similar experience or kiss with Hakari.
* {{Tsundere}}: Her defining trait. Usually a mild form of ''tsun'' in daily life (mostly shown in her honest, rude opinions) but the ''dere'' comes out rather easily when Rentarou gets in a serious mood.
[[/folder]]
[[folder:Shizuka Yoshimoto]]
-->'''Voiced by:''' Creator/ManakaIwami (voice drama)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shizuka_yoshimoto_0.png]]
[[caption-width-right:350:The CuteMute [[CuteBookworm Bookworm]]]]
A tiny classmate and book lover who becomes Rentarou's 3rd girlfriend after bonding over their shared passion for romance novels.
----
* AccidentalPervert:
** She accidentally sees Rentarou naked while trying to stop the other girls from doing so.
** She notices Meme hiding under Mei's dress, and lifts the skirt up to call her out ...only for Meme to [[NinjaLog disappear]], leaving her looking at Mei's underwear. They're both very embarrassed about it.
* AnimalMotifs:
** She has a slight one with rabbits thanks to her innocent cuteness and size. She gains actual bunny ears more than once, courtesy of Kusuri's drugs.
** She has also been compared to a squirrel on more than one occasion.
* {{Balloonacy}}: Is so small and light that she is swept into the air by holding onto ''a towel''.
* [[BigBrotherInstinct Big Brother/Sister Instinct]]: Rentarou's girlfriends and Rentarou himself are extremely protective of Shizuka. When Jurassic High's baseball team [[KickTheDog makes her cry]] to secure a win, [[RoaringRampageOfRevenge everyone kicks into high gear to utterly demolish them]].
* {{Catchphrase}}: "She laughed aloud".
* CompetenceZone: Due to her looks, she is often treated like a small child despite being the same age as Rentarou.
* CuteBookworm: Her defining trait. Loves fantasy romance books with a passion.
* CuteMute: Only speaks with her voice in dire circumstances, because her voice is so naturally quiet.
* TheCutie: Shizuka is one of the sweetest and most innocent members of the family.
* DarkHorseVictory: She’s the one who catches the bouquet, due to having been swept into the air by the breeze, and so caught it in the middle of a fight. She’s also the only one to walk in on Rentarou in the bath, her reaction to which was immense embarrassment.
* DeconstructedCharacterArchetype: Being almost mute caused most people to find her creepy and not associate with her, such that she had no friends before meeting Rentarou, and social interaction terrifies her, making her even more reluctant to speak, and so on. And considering [[AbusiveParents how her mother treats her]], any self-esteem she had would have dissipated long ago. Rentarou and his girlfriends are the first people to be kind to her ''at all''.
* EarlyInstallmentCharacterDesignDifference: Her hair color fluctuated in some of the earlier colored illustrations, ranging from green to brown, before settling with a [[ShyBlueHairedGirl dark blue.]]
* ForgotICouldntSwim: She tries to save Rentarou and Hakari when the duo fall into the Hanazono family pool...and nearly drowns due to being unable to swim, forcing Kusuri to save her.
* FriendlessBackground: Was afraid of even talking to others, let alone befriending them.
* MeaningfulName: Her given name Shizuka means "quiet" (referring to how quiet she is in general), while the characters for her family name translate as "a good book" (due to her being a CuteBookworm).
* MessyHair: It looks a bit unkempt, but it's just naturally curly. When Chiyo straightens her hair, Shizuka's attempts to keep it that way quickly turn into something resembling Whack-a-Mole.
* NiceGirl: Shizuka is a helpful sweetheart, something evident even with her trouble with speaking.
* OlderThanTheyLook: She's a teenager, but her looks, naïveté, and willingness to play a doll game with Kusuri makes that easy to forget.
* PhotographicMemory: Shizuka uses book text to "speak". By Rentarou's observation, this means that she's able to recall the passages of a book so well that she can flip to the page she wants (later scroll to the passage in the app she wants) immediately.
* RelativeButton: She's the button. A rival baseball team making her cry royally pissed the harem off and turned the tide of the game very quickly.
* ShrinkingViolet: Unbelievably bad at speaking up and relating to others (to the point of using book excerpts to communicate).
* SignatureLaugh: Not in the traditional sense. Her actual laugh isn't heard, but she uses ''her speech app'' to narrate her laughter. Even on repeat while being tickled.
--> "She laughed aloud".
* SophisticatedAsHell: Sometimes speaks in excerpts from classic novels, and other times from books that say, "No kiddin', man."

[[folder:Nano Eiai]]
-->'''Voiced by:''' Emiri Suyama (voice drama)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/nano_eiai.png]]
[[caption-width-right:350:The {{Emotionless|Girl}} [[TheAce Ace]]]]
The hyper-rational, intelligent, unfeeling 4th girlfriend, who became moved by Rentarou's sincerity.
----
* AcademicAthlete: She has shown herself to be extremely capable in many physical activities.
* TheAce: Not only the highest-scoring student in the school, but a decent athlete whenever she puts her mind to it, ''and'' pretty enough to have won a pageant over Mimimi with zero conscious effort.
* AmbiguousDisorder: It wouldn't be too outlandish to think she has some sort of psychological condition. Most of her behavior seems consistent with UsefulNotes/AspergerSyndrome.
* BadassBookworm: While it ''usually'' doesn't come to the fore even in the manga's few action-centric stories, it's played gleefully straight in the [[ItMakesSenseInContext maid-uniform watergun fight]], where she uses AwesomenessByAnalysis to match Mei's GunFu shot-for-shot.
* {{Bifauxnen}}: When Hahari has Nano crossdress, she pulls off the look of a {{bishonen}} man very well.
* BlueAndOrangeMorality: She views everything in terms of efficiency, from suggesting poison as a faster means of suicide than {{Seppuku}} to wanting to poke out the eyes of a friend's pets to incapacitate them.
* CannotConveySarcasm: Zigzagged. Her lack of emotion makes it difficult to tell if her comments that would come off as sarcastic from someone else are [[DeadpanSnarker actually sarcastic]] or [[LiteralMinded dead serious]].
-->'''Nano''': (''When Karane jams a piece of short bread into Rentarou's eye without looking'') So this is what "a feast for the eyes" means.
* ChekhovsGun:
** Her fear of heights is first shown in chapter 7 and gets exploited in chapter 26 to stimulate her appetite during an eating contest.
** Her ability to remember an insane number of digits of pi comes in handy in Chapter 83, when she orders the "Jugemu Jugemu Gonzalezurikire Kaijohnnysuigyou-no Suigyoumatsu Unraimatsu Fully-Made-Two Kuunerutokoro-ni Nomutororo Yaburakouji-no Bra-Burglar Paipopaipo Paipo-no [[Creator/ArnoldSchwarzenegger Schwarzenegger]] Shuuringan-no [[GratuitousGerman Guten Morgan]] Guurindai-no Ponpokopii-no Pen Island-no Choukyuumei-no [[Manga/JojosBizarreAdventure Josuke's]] Just Great-as-Hell Challenge Ramen" without missing a single word.
* ColdHam: You know things have gotten wild as hell when Nano foregoes her stoic nature by even a slight amount.
* TheComicallySerious: Nano's humorous moments borrow from her lack of visible reaction to anything and her blunt, calculating nature.
* CutenessProximity: Her brain tends to short-circuit when Shizuka is involved, logic and reason disappearing the minute Shizuka gives her puppy dog eyes. Once when Shizuka was made the subject of Mimimi's "beauty-seeking contest", Nano was only able to identify her "cute" features rather than "beautiful" ones.
* DeconstructedCharacterArchetype: Of the EmotionlessGirl. She’s actually very capable of feeling emotion but has consciously suppressed all feeling because it’s [[StrawVulcan illogical]], so once she feels romantic love for the first time she doesn’t know what to do. At the start, she scorns friendship, and her life seems completely unfulfilling before Rentarou comes along.
* DefrostingIceQueen: One of her defining traits. Her hyper-efficient approach to life made her realize her love for Rentarou but also told her to reject the relation as nothing efficient could come of it.
* DullEyesOfUnhappiness: Her default expression, even after having long accepted her feelings for Rentarou.
* EmotionSuppression: Does not allow herself to feel anything, and freaks out when this fails.
* EyePoke: Nano's preferred method of incapacitating someone is to poke them in the eyes.
* FlatEarthAtheist: PlayedForLaughs in Chapter 52, where she claims that it's pointless to honor the souls of the animals that make up her lunch. Cue Chiyo ''[[MediumAwareness flipping to an earlier chapter]]'' to prove that yes, Heaven exists in this setting.
* {{Foil}}:
** Her rational attitude is sometimes contrasted with Hakari's (who eschews rationality for her feelings).
** She is emotionless due to never smiling, while Mei is emotionless due to constantly smiling.
* FriendlessBackground: By her own choice, as friends are “inefficient”.
* FullNameBasis: How she addresses Rentarou and the other girls.
* GodivaHair: She loses her clothing in chapter 72 when the body-shrinking drug wears off, resulting in this trope when she wakes up in the morning.
* InconvenientAttraction: Unlike most of the other girlfriends she rejects her mutual attraction to Rentarou at first, seeing no purpose to it and attempting to end it. She gets over this at the end of their date, when she finds emotional attachment to photos she took with him at an amusement park.
* IntelligenceEqualsIsolation: Seemingly exaggerated before she started dating Rentarou. It's already evident that she limited her social interactions in her life out of maximizing efficiency, but the way she reacts to the attractions at the amusement park, you'd think she'd never even heard of amusement parks at all before.
* JerkassRealization: Having the chance to develop herself through her love for Rentarou enables her to realize how coldly she came off on Mimimi during the beauty pageant years earlier and apologize to her.
* {{Kuudere}}: After becoming the fourth girlfriend. She's still robotically stoic, but she's more social and caring than her first appearance.
* LudicrousPrecision: One of her CharacterTics is spelling out the percentage of something happening or being true.
* LuminescentBlush: All the girls do this, but with Nano it's the only sign that she's feeling positive about something.
* MouthfulOfPi: She recites a ludicrous number of digits of pi to ''stay focused''.
* NotSoAboveItAll: Participates in trying to see a glimpse of Rentarou naked, and is affected by the drug that makes the drinker want to do nothing but kiss her beloved as much as anyone else.
* PerpetualFrowner: She most likely thinks smiling is inefficient. She doesn't so much as smirk even when she's happy.
* PhotographicMemory: She can easily remember minute details, as demonstrated during the idol training arc and when ordering a ramen dish with a ridiculously long name.
* PrimalFear: She's afraid of heights. During the eating competition, she exploits this in order to stimulate her appetite.
* PurpleIsPowerful: She has purple eyes, and [[TheAce not only is she beautiful and smart]][[note]]She perfected ''every'' subject during the midterm exam, ranking her ''1st'' in the whole school[[/note]], [[ActionGirl she's also got some combat capabilities]] as seen when she was [[MundaneMadeAwesome exchanging shots with Mei on a water gun fight]] or [[BackToBackBadasses standing back to back with Mimimi to hold off]] [[ItMakesSenseInContext Hahari's perverted tentacle hair]].
* SlenderManStandIn: She has unusually long legs, wears a black jacket and tie, shows little (if any) emotions, and was the subject of school rumors before she began dating Rentarou. Also, her reasons behind maximizing efficiency in her life remain a mystery.
* TheStoic: Will have a neutral expression even when everyone else is freaking out.
* StrawVulcan: Has suppressed all emotions, including positive ones, because they are allegedly inefficient. She largely grows out of this once joining the group. She's still as logical and calculating as ever, but values Rentarou and the girls.
* VerbalTic: Uses "Efficient" or "Inefficient" a lot.
* WhiteHairedPrettyGirl: She has glossy silver-colored hair.
* WholesomeCrossdresser: Hahari dresses her in a typical prince outfit to wake up a "sleeping princess" (i.e. Rentarou, [[ItMakesSenseInContext unconscious and also crossdressing]]), and pulls the look off well.

[[folder:Kusuri Yakusen]]
-->'''Voiced by:''' Creator/HisakoKanemoto (voice drama)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/100kusuri.jpg]]
[[caption-width-right:350:The HotScientist and her [[TokenMiniMoe Loli Alterego]]]]
The crazy scientist of the group and the 5th girlfriend. Usually, a small hyperactive girl... until the drugs in her body are neutralized and she reverts to her original form, that is.
----
* BareYourMidriff: When in her original form, as a result of her clothes being too small to fit all the way.
* BerserkButton:
** Kusuri becomes utterly livid if someone messes with her smartphone, as seen when she snaps at her beloved grandmother for slamming her phone on the ground.
** She doesn’t take kindly to other people seeing Yaku as their granny.
* BewareTheNiceOnes: She doesn't show genuine anger until Chapter 84, and it is ''terrifying''.
* BlindWithoutEm: Kusuri can't see very well without her glasses in her older form.
* BoundAndGagged: Gets tied up and gagged by Nano in Chapter 13.
* BrainyBaby: Made her first new drug at eight months old.
* CallingYourAttacks: Tries to do this with a baseball pitch. Nano points out that that is silly and [[AwesomeButImpractical inefficient]], much to Kusuri's confusion.
* CatSmile: Shows up most of the time regardless of the form.
* DeconstructedCharacterArchetype: Represents the kind of HotScientist often seen in fetish works of the kind seen on Website/DeviantArt, and also overly sexualized lolis who are technically okay because [[OlderThanTheyLook they’re actually over 18]]. She vacillates between sexy adult and annoying child due to drug use, and the hilarious side effects of her fetish-enabling inventions actually come with serious consequences. The other characters lampshade her fetish attributes and find them unnerving, especially when she is aged down.
* DualAgeModes: Most of the time she's in her younger form, but she can return to her older form for 10-20 minutes if she takes a neutralization drug. She prefers her younger form for experiments, as her older form has poor eyesight and her hair can get in the way because it's longer.
* EasilyForgiven: There are no hard feelings about her almost trapping the other girls in an AndIMustScream state for the rest of their lives. To be fair, it was an accident, and she feels ''horrible'' about it.
* EveryoneHasStandards: She thinks that Naddy's refusal to "hold back" extends to not bothering with a JarPotty while watching TV, and is disgusted by such a notion.
* ExactlyWhatItSaysOnTheTin: ''All'' the names of her drugs are explanations for what they do. Thankfully for Rentarou and the girls, it gives them enough reason to not take the more dangerous ones.
* {{Expy}}: More or less a scaled-down version of [[Anime/TenchiMuyo Washu]], complete with red hair.
* {{Fangirl}}: She's a fan of the show "Pepepe no Pentarou", which shows in multiple chapters:
** She plays with a Pentarou doll with the others in chapter 29.
** At the karaoke bar, she sings the show's theme song.
** In chapter 91, she's inspired by an episode to pair the girls together as "equipment".
* FormFittingWardrobe: {{Averted}}. Many of her clothes in her default "child" form look rather loose, but that means she doesn't need to change clothes when she transforms back to her "older" form. However, [[SurprisinglyRealisticOutcome said clothes would also likely cover less skin than before]].
* FriendlessBackground: Sensing a pattern here? The difference is that she actually used to have friends before accidentally turning them into {{Technically Living Zombie}}s and alienating everyone else.
* GenkiGirl: Easily the most hyperactive of the girls. Though it's partly because [[CheerfulChild she's physically a child]]. She's more relaxed in her 18-year old form, but even then she can still get cheery.
* GreenEyedMonster: Gets jealous over Kishika calling Yaku 'Gwanny', protesting "She's ''my'' granny, yep yep!", and is wary Kishika is out to take Yaku from her.
* {{Hammerspace}}: Zigzagged. She has a wide variety of drugs that she can produce at any time, but she can't do ''everything'' imaginable with her drugs, and Chiyo does succeed in confiscating ''all'' of her drugs at one point.
* HiddenDepths:
** Gives up the once-in-a-lifetime chance to develop pharmaceuticals in America in order to help Rentarou rescue Hakari.
** She's something of a sumo fanatic and has regularly challenged the other girlfriends to square off against her.
** The reason she invented the immortality drug was so that her grandmother could live forever.
* HotScientist: 18 year old Kusuri is... a sight. It doesn't help that her clothes don't completely fit.
* IdenticalGranddaughter: Her child form looks almost identical to her grandmother Yaku's child form, although her hair's shorter and messier. Her older form looks pretty close to the brief glimpse of older Yaku we've had, but with glasses and, again, messier hair.
* IdiotHair: Has a giant one popping from the top of her head in both forms.
* InnocentlyInsensitive: Kusuri has a habit of casually insulting others without actually trying to, probably due to her child brain. Even when she makes accurate descriptions and compliments, the words she uses couldn’t be more tactless. Even her dead granddad isn’t safe.
* ItRunsInTheFamily: Chapter 74 reveals that not only are her mother and father drug developers as well, but her family have been in the drug-making business for generations.
* ItsAllMyFault: This is her reaction after the kissing zombie arc, as it was her drug that caused the problem.
* KissingUnderTheInfluence: Attempted twice in her introductory arc, but she fails both times. The first time, she serves Rentarou tea spiked with a LovePotion to get him to accept her confession, but he tries to regurgitate the drug when he finds out, and she has to administer a neutralizer when his body becomes overwhelmed by the drug. The second time, she drugs a thermos to get Rentarou to make out with her, but everyone thinks the thermos is for the girls, and the drug turns them into kissing zombies.
* MadScientist: Her defining trait. Good at creating potions that have disastrous side effects. In fact, her changing body is because she tested one of her creations on herself, and it's not the only time she tested drugs on herself.
* MagicAntidote: Almost all of her drugs can be negated with a common neutralizer. The most notable exceptions are her prototype immortality drug (where the effect is only temporary), her de-aging and body shrinking drugs (which would kill the user if consumed too early or at all), her father's bodybuilding drugs (which are actually strengthened by the neutralizer), and the version of the immortality drug used on her grandmother (which can't be negated at all).
* {{Malaproper}}: Frequently mixes up words.
* MeaningfulName: Her family name means "medicinal cooking" and her given name is a homophone for medicine or drugs.
* TheMindIsAPlaythingOfTheBody: Her body also slightly affects her mindset, such as her younger form having the energy befitting of a kid over her older form's slightly calmer disposition, or the latter being embarrassed playing with the Pentarou doll when moments ago she was playing just fine in her child form.
* MyGodWhatHaveIDone: Has this reaction when she finds out the girls drank from the wrong Thermos. She would have quit making drugs altogether had Rentarou not talked her out of it.
* MyGreatestFailure: When she first made the kissing drug, she didn’t know about its side effects, so is devastated when her friends are stuck like that forever. This caused people to avoid her after that, [[MyGreatestSecondChance until she meets Rentarou]], who loves her anyway.
* OlderThanTheyLook: She is 18 and used to actually look it. Then she took a drug that she thought would make her immortal but just made her look like a kid. In this form, she’s shorter than Shizuka!
* OneOfTheKids: Plays with dolls, doesn't really care about safety procedures, and cares more about looking cool with several baseball bats at once than actually playing the game. Though it's shown that the drug that makes her appear as a child factors into this. She’s visibly more ashamed playing with dolls in her grown-up form.
* OOCIsSeriousBusiness: When she drops her childishness and shows actual concern for someone, that concern is well placed. So far, this has happened during her FreakOut when she accidentally turns the girls into kissing zombies, when she chooses to help save Hakari instead of going to America, and when Iku passes out and has to go to the infirmary.
* PoorCommunicationKills: Thinks that it’s obvious which unlabeled Thermos is spiked with a LovePotion — [[MarsAndVenusGenderContrast Rentarou is male so the huge one is for him, while the small one is for the girls.]] Of course, everyone else thinks the big one is for five people and the little one for Rentarou, so when she leaves it unattended the girls drink the wrong one and turn into kissing zombies. And the worst part is that ''this has happened before''.
* ProfessorGuineaPig: Has a very cavalier attitude to testing her drugs on herself. Or on other people.
* PsychologicalProjection: Any time someone else leaves to go somewhere, she tends to jump to the conclusion that [[PottyEmergency they need to pee]].
* RuleOfCool: Tries to play baseball with two gloves and [[Manga/OnePiece three bats]], justifying it with the inherent coolness when questioned. [[RuleOfThree In the bonus page]], she tries to clean the field with two rakes, again justifying it with the inherent coolness when questioned.
* ShapeshiftingExcludesClothing: Kusuri's clothes don't change size when she changes forms, except for her lab coat, which seems to get ''smaller'' in her older form.
* TamperingWithFoodAndDrink: She spikes Rentarou's tea with a LovePotion when they first meet.
* ThirdPersonPerson: As part of her {{Kawaiiko}} aesthetic. This gives her away on two occasions: first when she tries to subdue Zombie!Nano while in her older form, and second when she [[FreakyFridayFlip ends up in Hakari’s body]] due to an unforeseen drug interaction.
* TokenMiniMoe: Parodied. She’s a year above Rentarou, and in her normal form, she’s a bombshell. Unfortunately, an immortality drug gone wrong caused her to look like a child unless she takes a temporary neutralizer. When Rentarou meets her after she reverted back, he has no idea she’s the same woman he felt become his soulmate. And yet she acts the age she looks most of the time.
* TVGenius: Her drugs can pretty much do anything at all, even if [[ItRunsOnNonsensoleum they make no sense]].
* UnaffectedBySpice: Supposedly a side-effect of her drinking so many experimental drugs all the time; it's what [[ThisLooksLikeAJobForAquaman allows her to win the Insanely Spicy Mapo Tofu round of the eating contest]] in Chapter 26.
* VerbalTic: Ending her sentences with "Yep yep!".[[note]]In the original Japanese version, it’s ”nanoda”.[[/note]] And sometimes "Nope nope!" depending on the situation. She does it less in her original form, and by then she only says "yep" once.
* WhatYouAreInTheDark: She's the only one who knows about her drug that makes people able to see infrared, and could easily keep quiet about it so that she can send it to the company she wants to work for. She immediately gives it up to help Rentarou and the others rescue Hakari.
* WomanChild: Justified. She acts like a young child because she's stuck in the body of one. She's more composed in her original form.

[[folder:Hahari Hanazono]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/hahari_hanazono.png]]
[[caption-width-right:350:The AbsurdlyYouthfulMother]]
Hakari's mother. Overprotective, cold, and focused... until she and Rentarou meet each other's eyes, at which point she becomes the 6th girlfriend.
----
* AbhorrentAdmirer: While she openly lusts after all the girls, daughter included, she has become increasingly attached to Kurumi the most, something Kurumi is less than thrilled about.
* AbsurdlyYouthfulMother: She’s 29. That’s right, she had her daughter at ''13''. This is because she was madly in love with a fellow classmate who suffered from [[VictorianNovelDisease a terminal disease]], and she, knowing he would not survive the year, got herself artificially inseminated with his sperm so that they could be a family before he died.
* AgeGapRomance: With her SecondLove, Rentarou. Being a 29-year-old widow in a relationship with a high schooler, and the oldest member of the harem until Yaku joined.
* AmazinglyEmbarrassingParents: Hahari's perverted antics are a frequent source of embarrassment for her daughter Hakari.
* BenevolentBoss: Hahari is shown to be very considerate of her maid Mei, as Mei is one of the few people Hahari displays any restraint towards, and she frequently shows concern for Mei's well-being.
* CameraFiend: Will unabashedly take photos of anyone in the harem acting or looking cute, [[StalkerWithACrush whether they're aware of her being there or not.]]
* CloudcuckoolandersMinder: To Mei. While [[LovableSexManiac Hahari herself]] is the ''[[DepravedBisexual furthest]]'' [[ComedicLolicon thing]] from a StraightMan, even she thinks the level of Mei’s devotion to her is insane and has to tone down her rigid sense of duty before she goes too far in carrying out her orders.
* ComedicLolicon: Has been {{Flanderized}} into this, with her actions (especially involving Kurumi, as well as during the hair chapter) crossing the line from funny to creepy.
* CommonalityConnection: Turns out Rentarou is not the only one to have more than one soulmate. The difference is that her previous lover is long dead, but it does mean that he can understand how she feels when she worries that dating Rentarou would betray her earlier boyfriend’s memory.
* CutenessOverload: She absolutely adores cute things, including but not limited to her soulmates and the shorter members of the family; when she first saw Mei, who was collapsed on the street in the snow, she decided to help because she thought she was just too cute.
* DeconstructedCharacterArchetype: Of the AbsurdlyYouthfulMother. To begin with, she's only as attractive as she is because she gave birth at a ridiculously young age, having impulsively decided to get pregnant before her terminally ill boyfriend died. Though she loves her daughter, she made immense sacrifices as a result and is paranoid that Hakari will get pregnant and throw her life away as well, leading to her imprisoning her child in her own home and threatening to kill her boyfriend. Then, the instant she meets said boyfriend, she loses it and proposes to him immediately, despite him being, you know, ''her daughter’s boyfriend'', and ''a teenager''. Even a decade and a half later, she still has no self-restraint and can’t stop pining over her dead boyfriend. Her character arc basically shows how psychologically damaged a MILF would have to be to actually reciprocate the fantasies of a teenage boy.
* DepravedBisexual: PlayedForLaughs because there is always someone to stop her before she goes too far, but she spends most of her time after joining the harem gushing over how cute Rentarou and the girls are. She frequently tries to start activities meant to emphasize that cuteness, and some of them are far too erotic for the girls to accept. Chapter 42 downright states her most basic desire is to grab and stroke anything cute, which of course includes the girls of the harem.
* EasilyForgiven: Once she becomes a soulmate, no one brings up her deplorable prior actions ever again, and as her character is developed they seem [[CharacterizationMarchesOn more and more out of character]].
* EveryoneHasStandards: Generally whenever she ponders and tries drawing a moral line, the girls are quick to call her a hypocrite. Nonetheless...
** Hahari for all her DepravedBisexual tendencies has never so much as asked for a kiss from Mei, because knowing full well Mei would literally do anything she asks, Hahari saw it as an abuse of power. Once she does, she asks specifically as Mei's friend and not her master.
** Even with [[ItMakesSenseInContext her drugged-up hair]] [[NaughtyTentacles playing tentacle with everything in range based solely on her own instincts]], the extras show that they only tickled [[PurityPersonified Mei and Shizuka.]]
** She also makes clear that Rentarou should ask Chiyo's parents permission before dating her at least, and when Rentarou informs her that her father is the one who set them up in the first place, she calls him out.
** After smacking Iku's behind once, she makes sure to ask permission before continuing.
** She expresses concern about Hakari's grades slipping if Hakari keeps getting caught up in delusions about Rentarou.
** After discovering Yaku's older than her, she's extremely embarrassed about having gone all CutenessOverload towards her, thinking she was a little girl.
* {{Fiction 500}}: Her house is enormous, the hallways have a laser security system to ward off intruders, she was able to get IVF treatment as a teenager, and she employs a legion of housekeepers who are trained to attack any boyfriend her daughter brings home. Once she joins the harem, she buys out their high school to become the “chairwoman” so as to spend time with him, despite having no teaching credentials. She lampshades this in Chapter 58 when asked how she managed to get thirteen outfits done for Rentarou's family overnight: "The power of capital is enough to make any ridiculous demand a trivial matter".
** In chapter 79, her parents are mentioned to have managed a company that sponsored a popular kids show when she was young, holding enough sway over said show that [[spoiler:the toys started having closed mouths due to Hahari French kissing her dolls]].
* FlowersOfFemininity: Like her daughter. Only they're ''all over'' her hair.
* TheFriendNobodyLikes: Apart from [[ExtremeDoormat Mei]], pretty much none of Rentarou's other girlfriends really respect her (despite all the authority she bought herself into at their school), and even her own daughter tends to be at most exasperatedly tolerant. Kurumi is particularly prone to putting her down whenever she gets handsy. Even ''[[NiceGirl Shizuka]]'' has snarked at her expense a few times.
* FriendlessBackground: After her boyfriend died, she refused to date anyone else out of fear of disrespecting his memory. For the next decade and a half, her only company was her daughter, her maids, and the mansion's guards.
* GagBoobs: Her boobs are so big that when she trips and falls while baserunning in Chapter 36, her boobs are able to touch the base and get her called safe, despite neither of her hands touching it.
* {{Gainaxing}}: When pitching a baseball, there is a closeup on her boobs, complete with a "BOING!" sound effect.
* GirlOnGirlIsHot: Gets a {{Nosebleed}} watching her daughter making out with Karane.
* GirlsLoveStuffedAnimals: She goes gooey over the Teddy Babies in Chapter 79, and is excited at the prospect of winning one in a quiz.
* HeroicBSOD: Temporarily isolates herself in her bedroom after her MyGodWhatHaveIDone reaction to covering the whole world in her hair.
* HypocriticalHumor: A good chunk of the jokes surrounding her are of this flavor.
* KarmaHoudiniWarranty: Brought up in Chapter 55, where Toruru points out that if word of her perverted behavior went public, she - and the people she pervs on, who are students at her school - would face serious consequences in society.
* KnightTemplarParent: Her daughter has a boyfriend, so what does she do? Imprison said daughter in her own home and ''try to kill the boyfriend''. Granted, this was also after finding out that her daughter had become part of a polyamorous harem, but straight-up murder is going too far.
* LikeMotherLikeDaughter: Her personal story shows she's as driven by her feelings as Hakari is (one of the reasons she does not approve of Rentarou at the beginning). Her fear of having her beloved daughter suffer the same things she suffered at her age explains a lot of her initial attitude.
* LovableSexManiac: She openly lusts after the other girlfriends, including her own daughter, nearly, if not more, than she does for Rentarou. The girls are very annoyed, but they mostly tolerate it because they know she means no harm. Some of her antics include:
** Convincing all the girls except Shizuka to peep on Rentarou while he's taking a bath (with the express purpose of seeing his peepee, as Kusuri delicately puts it).
** And then, crossdressing Rentarou and Nano just to enjoy the view and die of cuteness.
** Sneaking underneath Iku's hospital bed to take cute photos of her while asleep. [[WhatTheHellHero Kurumi is not amused.]]
* LoveFreak: Of the "I'm everyone's mommy" variety. A rather comically depraved variety.
* MaidCorps: She has numerous maids working in her mansion, two of whom are among Rentarou's soulmates.
* MeaningfulName: Hahari contains "Haha", the Japanese word for Mother.
* MrsRobinson: She absolutely adores cute things, like younger men... and Rentarou-chan and Rentarou-chan and Rentarou-chan...
* TheMourningAfter: Downplayed, as she does become one of Rentaro's girlfriends, but even so she feels guilty about betraying her first boyfriend's memory.
* MumLooksLikeASister: She doesn’t look much different than her daughter, especially during closeups.
* MyGodWhatHaveIDone: Does not take being responsible for covering the entire planet with living hair as a result of her impulsiveness well, to the extent that she locks herself in her room the day after. It takes Rentarou showing her that her hair didn't hurt anyone and that she [[ItMakesSenseInContext averted an early Ice Age by refueling the Sun with her hair, saving the planet]], to bring her out.
* NoHeroToHisValet: Sure, Mei adores her,[[note]]this is not an {{Inversion}} because Administrivia/TropesAreFlexible[[/note]] but her daughter Hakari often finds her behaviors bizarre and disappointing, though she learns to appreciate her more after the girls are accidentally turned into babies.
* NoseBleed: Experiences a pretty severe one while watching the cross-dressing fashion show Rentarou puts on for her. She experiences another while eavesdropping on Hakari and Karane when the latter two are in the bath.
* NotWithThemForTheMoney: On the receiving end of this with Hakari's father and Rentarou.
* OjouRinglets: Sometimes wears the full twin-set at home, though at school she usually opts for [[FashionableAsymmetry only one on the side]], and the rest tied back in a PrimAndProperBun.
* OlderThanTheyLook: At least in a school girl outfit, Hahari can pass off as a third-year student to onlookers. She's basically Hakari but with longer hair.
* ParentalIncest: Hakari is not exempt from Hahari's sexual perversions, and it's not anything new; as revealed in Chapter 44, she would often kiss Hakari when she was small, through her daughter doesn't remember it. Ironically enough, it happens again in the present, and she still isn't aware of it, [[ItMakesJustAsMuchSenseInContext as Hakari was asleep thanks to Kusuri's sleeping drug and Hahari, was blindfolded]]. The narrator has to tell the reader what happened because none of the characters know.
* ThePiratesWhoDontDoAnything: After she assumes the position of chairwoman, she is rarely seen running the school, just hanging out with Rentarou and the girls at recess.
* PsychopathicWomanchild: She is, quite possibly, ''the'' most messed-up character in the whole series, whether as KnightTemplarParent or DepravedBisexual. Nano comments at one point that it's hard to say her development since her intro has been an improvement.
* ShipperOnDeck: While she mostly wants to get intimate with them herself, she also enjoys any of the girls being intimate with either Rentarou or each other. Her biggest ship by far is Hakari and Karane; she nearly died of a nose bleed after spying the two bathing together, though admittedly the two were [[SkinshipGrope borderline having sex at the time.]]
* StepfordSmiler: Never got over the death of her boyfriend from middle school, and absolutely cannot handle romantic love.
* StrongFamilyResemblance: Flashbacks show her to have looked exactly like Hakari when she was that age, except for the long hair.
* StrugglingSingleMother: Hahari loves her daughter deeply, but she made it clear that raising her without Hakari's father was incredibly hard. She never wanted for money, but she describes it as a task that required her complete devotion and strength.
* TeenPregnancy: She gave birth to Hakari when she was 13 years old.
* TrademarkFavoriteFood: Shark fins.
* UnlimitedWardrobe: Hahari loves dress-up and has a gigantic closet filled with everything from costumes to baby clothes. If she doesn't have something specific, she'll pay for them to be tailored overnight.
* UnusuallyUninterestingSight: None of the girls to join the harem after her find it at all strange that she, an adult woman, is one of Rentarou's girlfriends (among whom is her ''daughter.'')
* WhatYouAreInTheDark: Shown in her first meeting with Mei. She didn't ''have'' to run outside and help a bedraggled, half-frozen urchin, but she did anyway. (Admittedly, it was because she thought Mei was too cute more than anything else, but still, she ''did'' help her.)

[[folder:Kurumi Haraga]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/kurumi_haraga.png]]
[[caption-width-right:350:The BigEater]]
A middle school student who is hungry all the time, and the 7th girlfriend, who unfortunately lashes out at people due to hunger.
----
* BigEater: Gets hungry very quickly, and her unusually fast metabolism is the only reason why she isn’t obese. (Although, not even Kurumi is immune from feeling sick if she eats ''far'' too much at once.)
* CuteLittleFangs: Possesses a little fang in her mouth.
* DeadpanSnarker: Shares this role with Karane.
* DeconstructedCharacterArchetype: She’s a BigEater because of a medical condition, which makes her obsessed with food to the point that it interferes with her day-to-day life.
* DefrostingIceQueen: To Rentarou at first, though mainly because of her hunger issues. She was also this to the harem, stating upfront that she only intended to be close to Rentarou. Her attitude changed after the eating contest, and she later on admits that she enjoys spending time with them.
* DoesNotLikeSpam: [[{{Irony}} Walnuts]]. She doesn't ''hate'' them, but she's been long sick of eating them every time she heard her own name, which is Japanese for "walnut".
* ExtremeOmnivore: She will even bite into inanimate objects if they remind her of food shaped like the aforementioned objects. She doesn't succeed in swallowing them, though.
* FatalFlaw: Gluttony. She'll even try to eat a baseball because it reminds her of candy.
* {{Foil}}:
** She and Hakari are both slaves to their passions. However, Kurumi doesn't like her food obsession but can do nothing to stop it.
** Like Karane, she's a tsundere. However, whereas Karane is a "traditional" tsundere, Kurumi has no control over when she's nice and when she's mean. She acts like a bitch when she's hungry and is nice otherwise.
* FoodAsBribe: A frequent victim of this trope, befitting her BigEater status.
* HeadphonesEqualIsolation: She wears big headphones and a hood to avoid hearing or seeing anything that would trigger her food obsession.
* HeroicSelfDeprecation: Since she’s not herself when she’s hungry (which is all the time) and pushes people away, as a result, she thinks she has zero redeeming qualities.
* HonorBeforeReason: When she reveals that she developed a craving for a french kiss in Chapter 44, she admits that she'd rather suffer with the craving than ask Rentarou for one because 1) none of his other girlfriends have gotten one and she refuses to get special treatment, and 2) Rentarou giving all of his girlfriends french kisses wouldn't be family-friendly.
* HyperactiveMetabolism: Gets hungry again quickly even after she's finished eating.
* InTheHood: She's only seen without her hood on when she's not wearing her jacket in the first place.
* InstantTasteAddiction: Exaggerated. She will start craving a food whenever she sees or hears anything that bears the slightest resemblance to it or its name.
* IronicName: A rare justified example: Kurumi means "walnut", and walnuts are the one food that she ''doesn't'' like... because her food obsession used to trigger so often from hearing her own name that she's sick of them.
* UsefulNotes/JapaneseHonorifics: Does ''not'' like being addressed as “-chan”, which Rentarou notes is a first for the girls.
* JekyllAndHyde: Usually a sweet girl, but once she becomes hungry, she becomes aggressive until her hunger is satisfied; she's practically a [[VideoGame/PokemonSwordAndShield Morpeko]] in human form.
* JerkassHasAPoint: Though she does yell too much when they first meet, the fact that a high school boy is taking such an interest in her when she’s in middle school would in fact be perceived as stalkerish [[FourthWallMyopia to someone unaware of the soulmates thing]], so it’s understandable that she constantly tells him to scram.
* LittleMissSnarker: Frequently mentions that the group is abnormal, and is one of the younger members of the group.
* MeaningfulName: Her last name is a pun on a phrase meaning "I am hungry", and is considered a somewhat rude one at that.
* NightmareFace: The expressions she makes when she's hungry can be rather [[DeathGlare unnerving.]]
* ObsessedWithFood: Pretty much anything can remind her of food.
* OneTrackMindedHunger: When hungry (which is almost always), she will become aggressive and can't help but think about the food she wants.
* OnlySaneMan: Whenever the subject is not food, she will [[LittleMissSnarker point out how insane the rest of the girls' eccentricities are]].
* OOCIsSeriousBusiness: To sell how she's desperate she is to relieve her french kiss craving, she admits that she would let Hahari be the one to do it if it meant her suffering would be relieved a little.
* OrgasmicallyDelicious: Her reaction when she gets to eat what she's craving.
* OutsideContextProblem: While she was able to control her cravings with food before, Chapter 44 has her deal with a craving for a french kiss after watching a movie one day.
* PickyEater: Downplayed. Once she starts thinking about a particular food, nothing else will satisfy her craving no matter how similar it is.
* SempaiKouhai: The ''kouhai'' to most of the cast. It even annoys her that she has the urge to pat Shizuka on the head.
* StraightMan: She considers herself second to Karane in this department.
* {{Tsundere}}: Though she's less of a parody than Karane. She's grumpy and hostile to everyone when she's hungry, but apologetic and demure when fed. She's also more upfront (albeit reluctant) about her feelings than Karane. According to Kusuri, her disposition is the result of the "hangry factor".
* WhatBeautifulEyes: Kurumi has striking eyes that are shaped differently than everyone else's, and Rentarou finds them beautiful.
* WingdingEyes: Her eyes turn into four-point stars when she's enjoying food.

Hahari's trusty maid, who becomes the 8th girlfriend after Rentarou gets her to open her [[EyesAlwaysShut always-shut eyes]].
----
* AllThereInTheManual: Her first meeting with Hahari, and the outline of her background, are covered in volume 4's bonus story. Her background was cut from the main manga for being so heart-rending it clashed too heavily with the tone.
* AmbiguouslyBi: Is obviously attracted to Rentarou, but is also so devoted to Hahari that it practically crosses the line into HomoeroticSubtext. The clothing she and Rentarou were picking out as a gift for Hahari made them both gasp at the thought of her wearing them. Even her compliance to (attempt to) kiss Hahari is based on her asking.
* AnimalMotifs: Mei is repeatedly compared to a dog, with how eagerly and excitedly she obeys her master's commands. She even gains ears and a wagging tail at times. Rentarou isn't too thrilled to make the comparison when she brings a cherry blossom branch to him at his request.
* BerserkButton: If you intend to cause Hahari harm in any fashion, you'd better hope she doesn't grant Mei permission to retaliate.
* BewareTheNiceOnes: Submissive to her masters she may be, but she doesn't take kindly to underlings who cause trouble for the people she knows.
* BlindDriving: She can drive a car ''while completely blind''. And then she repeats the stunt with ''[[ExaggeratedTrope a helicopter]]''.
* BrokenAce: She's ridiculously good at anything that's feasibly possible and isn't social, by virtue of being practically blind. Driving, water gun fights, trimming Mimimi's hair, etc. Unfortunately she's lacking in common sense and self-worth.
* CatchPhrase:
** "Understood."
** "If I may be so bold."
* ChekhovsGunman: She was a LivingProp for several chapters after Hahari joined the harem, before receiving ADayInTheLimelight culminating in her becoming one of the girlfriends too.
* DeconstructedCharacterArchetype: Mei embodies the fantasy of the servant who is utterly devoted to their master, who will obey their every command, who absolutely lives to serve... and as a result, she has nothing she lives for ''outside'' of her masters, not even herself. It turns out this is because she didn't value her life in the first place, her abusive childhood having effectively obliterated it.
* DeniedFoodAsPunishment: Implied. She mentions in chapter 89 that the food being served as part of the training would've been a veritable feast for her before she met Hahari.
* DisabilityImmunity: Because Mei's eyes are always closed, she's completely unaffected by the "steamy-as-hell challenge ramen", which was designed to hurt a person's eyes.
* EarlyBirdCameo: Her first confirmed appearance at the end of Chapter 20,[[note]]while it isn't confirmed, it's possible that she was the maid who informed Hahari of her daughter attempting to jump out the window[[/note]] where she provides Hahari with a coil of rope as she and Hakari head off to peep on Rentarou. In the next chapter, she escorts the girls up to the attic above the bath, and in the chapter after that, she and Hahari see off Rentarou and the girls as they head home to collect their school uniforms.
* EmotionlessGirl: To the point where even [[HypocriticalHumor Nano]] comments on it. She has no thoughts or desires that don't pertain to serving her master.
* ExtremeDoormat: She never questions a single order (real or perceived) from Hahari or Rentarou, to the point where she won’t hesitate to attempt suicide if she thinks she failed either of them.
* EyesAlwaysShut: Mei has kept her eyes shut for so long she's forgotten how to open them. Not being able to see, she relies on her other senses instead.
* {{Foil}}: To several of the other girlfriends.
** Mei is emotionless due to constantly smiling, while Nano is emotionless due to never smiling.
** Mei is willing to hurt herself if it means obeying what she thinks are orders from her master, while Iku is willing to hurt herself purely for pleasure.
** Mei is completely obedient to Hahari (and later Rentarou) to a fault, while Naddy doesn't hesitate to assert herself against Hahari despite the latter being the former's boss.
** Mei is older, a flawless maid, and devoted to her masters. Mai is younger, a {{cute clumsy|girl}} {{maid}}, and devoted to Mei especially. Mei's devotion compels her to go above and beyond in the name of duty, while Mai's devotion distracts her from her duty. Mei is an ExtremeDoormat, while Mai knows full well what she wants, and takes action to get it.
** Mei and Momoha were kicked out of their family's homes and eventually found by Hahari, and they both do work for her in exchange for living where they work. But while Mei's parents disowned her due to being crippled by loan shark debts, Momoha was disowned because her parents thought she was doing too much for them.
* GratuitousFrench: The song she sings at the karaoke bar has French lyrics.
* GrewASpine: Downplayed. Her second {{Catchphrase}} "If I may be so bold" is first spoken in chapter 54. It's a sign that she's learning to be more assertive.
* HandicappedBadass: Mei might effectively be blind, but her other senses are so sharp that she can do anything a person with sight can do, and she's consistently portrayed as one of the most competent members of the family.
* HappinessInSlavery: [[DownplayedTrope Not quite slavery]], but she turned down an offer to be adopted into the Hanazono family in favor of working as a live-in maid.
* ImprobablePilotingSkills: Can fly a helicopter while blind.
* LoveAtFirstSight: Literally. While all the girls start falling for Rentarou this way, Mei is introduced to him several chapters before she's revealed as one of his soulmates when she makes [[EyesAlwaysShut actual eye contact]] with him.
* {{Maid}}: Of course!
* MajorInjuryUnderreaction: She never reacts to any kind of injuries (real or fake) more strongly than in a calm manner.
* NightmareFace: As her eyes-open portrait demonstrates. While her eyes are ''[[TakeOurWordForIt supposedly]]'' lovely rainbow-like things, that can't really come across in a black-and-white medium. Combine that with the fact that she can only open those bright eyes when she’s [[OhCrap shocked]] or [[GameFace about to wipe the floor with you]]...
* NinjaMaid: She is unexpectedly agile in her maid uniform, to Karane's shock when she effortlessly dodges out of the way of her squirt gun. She's ultimately the last one standing in that game, only to be disqualified on a technicality. (Not that it matters, because Rentarou kisses everyone anyway as a reward.)
* OhCrap: Invoked by Rentarou. Realizing the humiliating story he told her was about Hahari and not Rentarou is what finally causes her to open those bright eyes. Afterward, it's notable that the only time her eyes open is when she's having a moment like this.
* OOCIsSeriousBusiness: She has also been seen with open eyes when she's donning a GameFace.
* ParentalAbandonment: Mei reveals in volume 4's bonus story that her parents, who were deep in debt to loan sharks, [[AbusiveParents abused her]], then eventually abandoned her to make her own way on the streets. By the time Hahari first met her, she already put little to no value on her life.
* PerpetualSmiler: Believes a maid should never stop smiling in front of her master. For some reason, this includes having her eyes closed, too.
* PhraseCatcher: "That wasn't an order!"
* RecruitedFromTheGutter: After Hahari learned Mei had been abandoned to wander the streets by her AbusiveParents, she and Hakari offered to adopt her as part of the family. Mei couldn't accept that, so she instead agreed to become a live-in maid.
* SatelliteCharacter: Deconstructed. Mei is so devoted towards Hahari and Rentarou that making her own decisions is alien to her, and sees no value in taking care of her self. Rentarou and Hahari make efforts to break her from this.
* StevenUlyssesPerhero: Her family name is Meido, and she's a maid (though they're not written the same way in Japanese).
* SuicideAsComedy: Has a bad habit of offering to kill herself if she makes a mistake while serving her mistress. Hahari is very fast to talk her out of it.
* SuperSenses: Due to having her EyesAlwaysShut, blindfolds and blinding attacks have no effect on her, and her other senses are heightened to ludicrous levels.
* SurprisinglyRealisticOutcome: Normally a character with EyesAlwaysShut is just a design choice and they can see perfectly fine. Mei is actually blind because her eyes are always closed.
* TechnicolorEyes: Mei has hypnotic, rainbow-colored eyes.
* UndyingLoyalty: Mei takes this to an extreme; she has no interests outside of serving her masters (Hahari and Rentarou), and she will obey any order given to her no matter how dangerous it may be to her health. She sees no value in taking care of herself because all she values are being of use and worth to her masters. Rentarou gets her to realize that her mere existence is valuable to him.
** She has also believed Kurumi to be giving her orders on occasion.
* WhatBeautifulEyes: Her eyes are ''rainbow-colored'', which Hahari comments on. Too bad that she rarely opens them.
* WholeEpisodeFlashback: Her backstory was relegated to a bonus chapter due to [[TearJerker clashing too heavily with the rest of the manga]].

[[folder:Iku Sutou]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/img_20201130_090311.jpg]]
[[caption-width-right:350:The [[PassionateSportsGirl Sporty]] [[TooKinkyToTorture Masochist]]]]
The 9th girlfriend. She is the only available member of the Girls' Baseball Club, and a major masochist.
----
* {{Bokukko}}: Uses the ''[[UsefulNotes/JapanesePronouns boku]]'' pronoun, and Rentarou mentions her "boyish charm".
* BoyishShortHair: Iku has short neck-length hair, befitting her status as a tomboy.
* {{Catchphrase}}: “It hurts…!❤️”
* CharacterTics: She has a habit of scratching her cheek when embarrassed.
* ClarkKentOutfit: She's not overly buff and appears to have the average muscle build of a teenage girl, but she has a toned figure underneath her outfit.
* ADayInTheLimelight: Shares one with Mei in Chapter 89, which sees the two of them embark on intense ascetic training.
* DeconstructedCharacterArchetype: Somehow, "[[PassionateSportsGirl sporty girl enthusiastic about her dying club]]" becomes "masochist obsessed with TrainingFromHell", determination getting exaggerated into masochism, then looping back round into determination again. She's so determined to train she collapses due to spending all night swinging, not even her masochism enough to keep her going.
* {{Determinator}}:
** Trains overnight to the point she collapses, in response to how Rentarou and the others helped her.
** Also parodied: at one point, she declares "If there's something I can't do, then that just means I wasn't trying hard enough!", which is fairly standard determinator-speak... except she's talking about filling in for an entire baseball team by herself.
* DidntThinkThisThrough: The reason why her club is about to be disbanded is that the other members went to America to study, with only her behind. Rentarou even calls this surpassing tunnel vision.
* {{Foil}}: Iku endures pain out of pure enjoyment, while Mei endures pain if she thinks it's her master's request.
* GoneHorriblyRight: When she was much younger, Iku was a crybaby who would give up on something once it got too tough. Her older brother tried to correct this once she started getting into baseball by telling her that she had to keep at something to improve at it, [[{{Determinator}} even if it hurt.]] Unfortunately, Iku came to the conclusion that "if powering through pain = getting better, [[ComicallyMissingThePoint then pain = a good thing]]", which awakened her masochism.
* HeroicRROD:
** Spends all night practicing her swing, then immediately passes out once she meets Rentarou and the girls the next day.
** [[PlayedForLaughs More comedically]], it's later revealed that she does this to herself on purpose so that her muscles are in a constant state of pain. When Momiji forces her into a massage to alleviate it, Iku starts ''crying in remorse.'' The effect is compared to a case of ReviveKillsZombie.
* IAmNotPretty: Downplayed; she thinks she looks plain compared to the rest of the harem, consisting of beautiful women and cute girls.
* IronicName: "Sutou Iku" is a pun on "[[GratuitousEnglish stoic]]". She is anything but.
* LoudGulp: A frequent reaction to seeing something that could be painful.
* MadnessMantra: Tries to sneak out of the infirmary after passing out from exhaustion, still saying, "Practice... gotta train..."
* ReviveKillsZombie: One of the few things that can upset her is when Momiji massages away her carefully cultivated muscle pain.
* TomboyWithAGirlyStreak: She's as tomboyish as they come, but is perfectly happy to wear a skirt for her movie date with Rentarou.
* TooKinkyToTorture: She's a masochist that gets off to pain, physical or emotional. Even getting her ''heart broken.''
** According to Momiji, Iku's always in extreme pain due to her workouts causing muscle damage, to the point that Momiji wonders how Iku is able to even walk let alone act normal.
** She also deliberately messes up her concentration in chapter 89 so that the machine monitoring her keeps smacking her. The ReadingsAreOffTheScale when the monk overseeing the training returns.
* TraumaButton: She once hit a homerun that injured a girl in the audience, and since then standing in the batter's box causes the memory to resurface, and she freezes.
* {{Understatement}}: Says she is going to get in a little more practice after everyone leaves... and when they all return to school the next morning, she's done ''more than 100,000 practice swings'', having been there all night without a break. To her, this is perfectly normal.[[note]]And since there are only 86,400 seconds in a day, and she was only there for about eight hours, she must have managed to do about four or five swings per second! Of course, that's assuming her counting wasn't thrown out of whack during that time.[[/note]]
* VerbalTic: Parodied. Her dialogue balloons have heart symbols when she's experiencing pain.
* WhenSheSmiles: Chapter 36 ends with her giving a huge smile after hitting a walk-off grand slam and kissing Rentarou after he caught it, telling him she loves him.
* WholeEpisodeFlashback: Volume 5's bonus chapter is Iku's older brother Ikuya explaining how she became a masochist.

[[folder:Mimimi Utsukushisugi]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/screenshot_2020_11_30_08_57_47_92.jpg]]
[[caption-width-right:350:The {{Narcissist}}]]
The 10th girlfriend. She is Rentarou's upperclassman by one grade and is obsessed with looking beautiful.
----
* AttentionWhore: She absolutely adores being the center of attention, even using this desire to distract a CameraFiend trying to snap photos of Meme.
* {{Catchphrase}}: "Naturally." In Japanese, it's "Ustukushi", which is part of her surname.
* ComicallyMissingThePoint: When Meme mentions wishing she could be more like Mimimi, the latter thinks Meme wants to look as beautiful as her, even though Meme was actually talking about having confidence in herself.
* DeconstructedCharacterArchetype: Of the {{narcissist}} obsessed with their own beauty. As far as she's concerned, beauty can't simply be bought, it has to be worked for as well, and she puts a lot of work into making herself beautiful, earning her own money, cutting costs wherever she can, doing facial regimens, and teaching herself elocution.
* EndearinglyDorky: Mimimi puts on an air of sophistication as another layer of beauty. While she ''can'' be genuinely dignified at times, her blatant attempts to stay that way and inability to act modest towards compliments (imagined or not) make her appear more "cute" than just beautiful. Rentarou lampshades as much about the latter on their first date.
* TheFashionista: Takes pride in dressing well and dresses up Rentarou in her style.
* {{Foil}}: To Meme. Mimimi constantly works towards being beautiful, while Meme tries to make herself stand out less. Mimimi loves being noticed and admired, while even ''slight'' attention being thrown her way causes Meme to make herself disappear.
* ForeheadOfDoom: Mimimi's hairstyle shows off her prominent forehead, which has at least once been used to pull off the classic BlindedByTheLight gag
* GoshDangItToHeck: She never uses any profanity, no matter how mild.
* HairOfGoldHeartOfGold: Mimimi's official hair color is blonde, and in a departure to the usual {{Narcissist}} she values ''inner beauty'' the most and is supportive towards others. At worst she's just condescending without actually being malicious.
* HiddenDepths:
** She believes that beauty isn't simply bestowed and it has to be created through continuous effort and earns her own money in order to do so. When a guy jeers at her, she ignores it, telling Rentarou that being envied is a consequence beautiful people must accept. She also views beauty as involving more than just external appearances, seeing Rentarou as having a beautiful heart.
** Besides her beauty, her part-time job as a newspaper courier makes her a VERY fast runner.
* HoistByHerOwnPetard: Her skin is so smooth that Rentarou is unable to maintain a firm grip on her during the sumo tournament. But it also makes it harder for her to stand barefoot, causing her to lose.
* LargeHam: She's nothing if not flowery in her mannerisms.
* MeaningfulName: Mimimi is "beautiful" repeated three times, and Utsukushisugi means "extremely beautiful".
* {{Narcissist}}: Lampshaded by Rentarou. To the point where she expresses envy towards him for dating ''her'' when they just met. Although she does love Rentarou for his inner beauty.
* NonUniformUniform: She pretty much doesn't wear the uniform at all, instead wearing a bodice over her top and fancy stockings and boots below her skirt. Yet she still designs something completely different when Naddy has the girls dress the way they always wanted to instead of what the school demands of them.[[note]]Given that her "freedom outfit" was three times as tall as herself, it's understandable that her normal outfit is what it is.[[/note]]
* NotGoodWithRejection: Downplayed. Nano coldly rejecting her hand at friendship made her sensitive to it, which she admits is what made her act oblivious to Rentarou questioning her upfront proposal to be his girlfriend.
* ThePratfall: Her skin is so smooth that if she takes her shoes off and the ground under her is smooth, she risks slipping and falling.
* ProudBeauty: ''Very'' much so, though it's made clear in her introduction chapter that she's proud because she puts so much work into being beautiful.
* PunnyName: To English speakers, Mimimi [[LuckyTranslation happens to sound like]] "Me, me, me!" which plays into how she comes across as a vain narcissist.
* TheRival: To Nano. In the past Nano had bested Mimimi in a beauty pageant (Which Mimimi orchestrated for Nano to sign up for in the first place) and [[GracefulLoser when Mimimi offered a hand in friendship]] Nano, already deep into being an emotionless logic-driven being, snubbed her. This caused resentment in Mimimi in the present and she challenges Nano to a beauty contest for Rentarou's affections.
* StatuesqueStunner: She has a few inches over Rentarou and the rest of the girls (Aside from [[BigBeautifulWoman Yamame]]).
* StepfordSmiler: Parodied. When put in less-than-comfortable situations, like getting cramped in a photo booth with several people or in the middle of a storm, she just smiles to endure.
* StraightMan: Zig-Zagged. On occasion she snarks at the series’ weirdness, though her own narcissism tends to mess it up half the time.
* VerbalTic: Tends to say "naturally" and "of course" a lot, especially when explaining something or receiving (what she thinks is) a compliment.
* WorkplaceAcquiredAbilities: Uses her beautician skills ([[ImprobableWeaponUser and a hair brush]]) to parry Hahari's attacking hair.
