[[caption-width-right:200:[[OrdinaryHighSchoolStudent Manabu]] and [[JapaneseDelinquents Reina]]. Actually, you could call them [[FlunkPunkRumble Megane-kun and Yankee-chan]], if not for copyright issues.]]
Tanaka Manabu is a regular honors student. On the way to school, he meets a girl carrying a bloody bat. That girl is Ryuuzaki Reina, leader of the school's female delinquents. It's love at first sight. ''Yandere Kanojo'' is a gag manga (with a combination of {{yonkoma}} and normal page) about having a yankee dere-dere girlfriend.

A drama CD came out in Japan in 2010.

NOTE: In the title of this series, "yandere" refers not to [[{{Yandere}} this term]], but to the "[[JapaneseDelinquents yankee]]"+ "dere-dere" combination. In this sense, 'yankee' means troublemaker, ''not'' an American.

Not to be confused with Manga/{{Onidere}}, which has a strikingly similar concept, but is only similar to this series in that regard.
----
!!Tropes in Yandere Kanojo
----
* ADayInTheLimelight: Reina's parents in their flashback chapters, and Hijiri and Shiratori in chapter 27.
** Sumika and Nanami in ''their'' flashback chapters, and Shiratori solo in chapter 34. A-ko in chapter 37 and Hiromichi (the cafe manager) in chapter 39.
** Even Nanami's minions get one in 40.1.
* AbsurdlyYouthfulMother: There are at least two in this story Ran, Reina's mother, and Azami, [[spoiler: Manabu's mother.]] [[JustifiedTrope Justified]] for [[spoiler:Azami]], she had her child when she was still in highschool.
* TheAce: Shiratori ''would'' be this if anybody treated him with any respect - he ''is'' good at sports and academics, good looking, and popular with the ladies...except the girls like his [[{{Adorkable}} adorkability]] and Manabu and Reina treat him as an UnknownRival and ButtMonkey.
** Azuma is a straighter version of this trope. He's actually so cool, both his grandchildren are acting out of character when he's present.
* AchillesInHisTent: Subverted. [[spoiler: Azuma notes that as the head of the Tanaka family he could ''easily'' solve Manabu's dilemma, but chooses not to because he doesn't want to undermine Aoi's authority. He didn't however, have any objections with letting Reina hold him hostage.]]
* {{Adorkable}}: Shiratori thinks he's popular with girls because he's so cool. In reality, he's popular with the girls because they find how easily-flustered he gets when they flirt with him adorable.
* AllAmazonsWantHercules[=/=]SingleWomanSeeksGoodMan: Played straight ''both at the same time'' with Ran and Kouichiro.
** Well, Ran ''thinks'' she wants Hercules, and [[FaceOfAThug that Kouichiro fits the bill]], but it's [[SubvertedTrope subverted]] when he turns out to be a wimp, and she's head over heels in love with him anyway.
* AllGaysArePromiscuous: Shuuei Mori. In his introductory chapter, the first thing he says to every guy he meets is "Hey, wanna go to a hotel later?".
** [[{{Wimpification}} Then he meets Azuma and, well....]]
* AllMenArePerverts: [[http://www.batoto.net/read/_/7597/yandere-kanojo_ch2_by_c-k/9 HOLY]] [[http://www.batoto.net/read/_/7597/yandere-kanojo_ch2_by_c-k/15 SHIT]] [[http://www.batoto.net/read/_/7598/yandere-kanojo_ch2.5_by_c-k/9 MANABU]]!
** To put it simply, it WOULDN'T be a big problem if the guy saying it was NOT a [[TheStoic Stoic one]].
* AlliterativeFamily: The Shiratori siblings: Tsubame, Tsubasa, and Tsugumi.
* AmazonChaser: Manabu met Reina when she was carrying a bloody bat.
* [[spoiler:AnAstralProjectionNotAGhost: Misaki/Kuroko. In a subversion to the way this normally gets used, however, when she finally gets her memories back, she dies shortly afterwards, her astral projection fading.]]
* AprilFoolsPlot: The subject of chapter 27.1.
* AtArmsLength: Reina does this to Nanami the first time they fight.
* AuthorAppeal: The author likes characters that look tough, but aren't, and who have '[[FaceOfAThug evil eyes]]' - hence Reina's dad. Similarly, because he likes old guys, he included Manabu's grandad.
* BadassGrandpa: Grandpa Tanaka. At least until a decade ago, as of 42.5.
** WarriorTherapist: He can make a DomesticAbuser shed TearsOfRemorse through GoodOldFisticuffs.
* BeCarefulWhatYouWishFor: Reina really should, especially when a certain clown might be listening.
* BeachEpisode: Chapter 17.1.
* BearsAreBadNews: Subverted in one chapter. Manabu is worried about encountering bears when he and Reina are in the mountains looking for a Sakura tree. Reina reassures him and says she'd gladly kill and ''eat'' any bears threatening them. A bear overhears them and is absolutely terrified.
** [[InvertedTrope Bears think]] [[{{Badass}} Reina]] is bad news.
** Except when the bears are Grizzlies (chapter 28.1), then this trope is played straight... until Reina sacks it [[AttackItsWeakPoint in the knee]], then the bear relents and [[DefeatMeansFriendship shows her some respect]].
* BerserkButton: If Reina considers you to be a friend, consider it to be a nice privilege. If she feels that you've betrayed that feeling, however, ''[[http://www.batoto.net/read/_/47511/yandere-kanojo_ch33_by_vexed-scans/7 God]] [[http://www.batoto.net/read/_/47511/yandere-kanojo_ch33_by_vexed-scans/8 help you.]]''
* BetaCouple: Manabu and Reina are essentially this to Hijiri and Shiratori, even though they're the main characters while Hijiri and Shiratori are secondary characters. This can be tricky (in that the Hijiri/Shiratori story has been one story arc in one of the two published titles), and Manabu and Reina may swap back into the alpha couple once the story arc concludes.
* {{Bifauxnen}}: Akira's a variant on this, being a 'sporty' Bifauxnen rather than an 'elegant' one. She's also quite happy to wear female school uniform.
* BigBraToFill: [[http://www.batoto.net/read/_/7619/yandere-kanojo_ch18.5_by_vexed-scans/10 Lampshaded.]]
* BigBrotherInstinct: [[spoiler:Reina's uncle's dog feels this way toward Reina; that's why he dislikes Manabu, because he feels that Manabu isn't strong enough for Reina.]]
* BigDamnHeroes: [[spoiler:Manabu saves Chibita and Reina from attacking cats using dried bonito as a diversion.]]
* BigFriendlyDog: [[IronicName Chibita]], Reina's uncle's dog. [[spoiler:Except around Manabu.]]
* BilingualBonus: There are a lot of puns in this manga that wouldn't translate to English well.
* BirdsOfAFeather: Manabu and Hijiri comment on how similar they are during a talk in chapter 33.
** The manga occasionally points out the similarities between Reina and Shiratori.
** [[spoiler:Not to mention Mayami and Manager.]]
* BishieSparkle: Shiratori, in his initial appearance.
* BittersweetEnding: Nanami and Sumika's flashback. Sweet, in the fact that [[spoiler: Sumika becomes friends for real with Nanami and Nanami's dad returns and reconciles with his family]], bitter in the fact that [[spoiler: his new job means that Nanami has to move far away from Sumika.]]
* BlahBlahBlah: How Reina summarizes the need for Manabu's grandfather to help them teach Akira to feel more girly.
** Becomes an actual form of communication [[http://www.batoto.net/read/_/7635/yandere-kanojo_ch26.5_by_vexed-scans/11 here]].
-->'''Hijiri:''' '''''Please go back to using normal words!'''''
* BlandNameProduct: Reina's dad buys a [[PlaystationPortable "Play Halaytion Portable"]] along with a certain game [[VideoGame/MonsterHunter about partying up with others to hunt monsters]] that's extremely popular in Japan.
* TheBlindLeadingTheBlind: Akira, a crossdressing tomboy, asking Reina to teach her how to be more feminine.
--> '''Reina:''' [[LampshadeHanging You should really find a better person than me for that.]]
* BokeAndTsukkomiRoutine: Reina and Mayami do this so often that Reina eventually has Mayami playing tsukkomi in her head when she's not around.
* BreakingTheFourthWall: All over the place.
** The Valentine's Day special is filled with this.
*** The chapter opens with Hijiri, Mayami and Reina in a {{Fanservice}} shot. The next page shows them "backstage" fixing their hair.
*** Reina asks why they're in these clothes and after being told it's for Valentine's Day, she questions if that's okay because the chapter is being printed in the July issue.
*** Hijiri remembers how Manabu got only one panel in the issue that was in color, and questions if that's really fair to the main character of the manga.
*** Mayami snarks that the mangaka's lack of seasonal awareness is going to get the characters caught up in a situation when they're NotAllowedToGrowUp.
** "What is with that expression that looks like it's saying 'What a pain in the ass' in bold face Ming type font?!"
** Reina casually explaining to the readers about the FamilyFriendlyFirearms, complete with Manabu lampshading it.
--->'''Manabu:''' You look really distant...
** The whole conversation between Reina and Mayami about the Tanakas' family situation. They even say they're BreakingTheFourthWall to avoid MoodWhiplash.
** Reina questions why Sumika gets two panels for her introduction at the beach.
** Reina yells at the school doctor to shut up and act like "a little side character".
** "He'd never draw us in swimming caps anyway."
** "Wait, I've hardly had any screentime thanks to your ass!!!"
** In chapter 35.1:
--->'''Reina:''' Ahh! You're right!! I forgot about that part of the plot!!!\\
'''Manabu:''' [[LampshadeHanging Reina, the fourth wall!!]]
** The omake for 12.1 has Reina and Mayami discussing why Manabu got momentarily bishified.
* ButtMonkey: Shiratori. He has only his own WrongGenreSavvy to blame - he wants people to be impressed with his good looks and talent at academics and sports, and Manabu to treat him as TheRival. There's a time and a place for that...[[GagSeries and this is not it.]]
** [[GoldfishPoopGang The Kuroboshi Girls]]. To be fair, [[BigBadWannabe they bring it upon themselves]].
** Tsukihitsugi. She wants to hunt ghosts, but has no spiritual powers and the only reason why she encounters them is because, as [[StringyHairedGhostGirl Kuroko]] says, her mere ''presence'' is incredibly annoying to spirits.
--->'''Kuroko:''' You can think of her like a huge pile of shit that only spirits can smell.\\
'''Reina:''' That's a pretty harsh way to put it.
* CannotSpitItOut: Shiratori, [[spoiler:to the point that ''[[NiceGirl Hijiri]]'' [[OOCIsSeriousBusiness takes matters into her hands.]]]]
** [[spoiler: [[http://www.batoto.net/read/_/155473/yandere-kanojo_ch48_by_vexed-scans/10 He gets better.]]]]
* CaptainErsatz: [[LightNovel/{{Toradora}} Taiga]], [[http://www.batoto.net/read/_/7605/yandere-kanojo_ch7_by_cccr/9 is that you]]?
** Shiratori was based off of the rival character in TokimekiMemorial 3, because the author hated him and wanted to see him get beaten up. That said, the author does like Shiratori (though he's not feeling the love).
* CatSmile: Reina occasionally pulls this off, and it's adorable.
* CatsAreMean: To be fair, it's Chibita who strikes first...
* [[TheDogBitesBack The Cats Strike Back]]: [[http://www.batoto.net/read/_/89800/yandere-kanojo_ch37.5_by_vexed-scans/10 Chibita tries to scare a cat stealing a fish. The retaliation is swift.]]
* CerebusSyndrome: What started out as a goofy gag yonkoma has been getting steadily more serious since the introduction of Manabu's family situation.
* CharacterDevelopment: Reina gradually becomes more honest about her feelings and less violent towards Manabu as the series goes on.
** Shiratori makes less of an effort to be obnoxious around the gang, though he still wants to be recognized by Manabu as a rival and as a friend. He's unwilling to admit the latter, however [[spoiler:(at least until chapter 35)]].
* CharlesAtlasSuperpower: Hilariously, Manabu himself, postulated to be the effect of Reina's constant abuse prior to her CharacterDevelopment. As Reina found out hard, she ([[FreakyFridayFlip in Manabu's body]]) made her original body [[GlassCannon seemingly fragile]] in comparison.
* TheCharmer: Azuma in spades.
* ChildHater: Sumika. The reason why, however, is different from most examples.
--->''"I hate kids. They're all just so stupid, selfish, never listen to what people say and worst of all, they can't do anything. [[HeroicSelfDeprecation That's exactly why I've also found myself so repulsive.]]"''
* ClassRep: Hijiri.
* ClusterFBomb: Reina's pretty foul mouthed when she's angry, unsurprisingly for a {{delinquent}}.
* [[CombatSadomasochist Combat Masochist]]: Mayami likes to provoke Reina into hitting her so that she can get off on the pain.
* CoolOldGuy: Manabu's grandfather literally puts him to shame - he has such a complex about his granddad being so much cooler than him that it's far and away the leading cause of any NotSoStoic moments he has.
** [[GrandmaWhatMassiveHotnessYouHave Grandpa What Massive Hotness You Have]]: He also hasn't lost his charm either, just ask Akira.
** [[spoiler:He makes a natural {{seme}} go {{uke}}. {{Yaoi Fangirl}}s can't get anything cooler than that.]]
*** [[spoiler:may also apply to Kuroko, as we can see from her comatose body]]
* CooldownHug: Kouichirou to Ran in [[http://www.batoto.net/read/_/85876/yandere-kanojo_ch37_by_vexed-scans/16 Ch 37]]
* CosmeticCatastrophe: Reina starts out well when learning how to use makeup, getting Mayami to help her, but when she tries to go solo, it descends into this.
* CovertPervert: Reina has a tendency to warn Manabu not to do or think of perverted things that never occurred to him.
** To be fair, Manabu makes some strong hints that [[http://www.batoto.net/read/_/7630/yandere-kanojo_ch24_by_vexed-scans/4 he's a Covert Pervert too]].
*** Chapter 46.1 brings it UpToEleven. [[http://www.batoto.net/read/_/153162/yandere-kanojo_ch46.5_by_vexed-scans/6 Point in case.]]
** Reina has [[http://www.batoto.net/read/_/7614/yandere-kanojo_ch16_by_vexed-scans/12 her moments]] as well.
* CryCute: Can't be more Dere-dere than that.
* CurbStompBattle:
** The Kendo Club shows up to defend the school from a possessed Reina, which ends exactly how you'd expect it to. Then the Judo Club shows up only to suffer the same fate.
** A-ko was trying to fight Ran for Kouichiro's love. She never stood a chance.
* DarkAndTroubledPast: Manager has an... interesting childhood. It's presented as BlackComedy.
** [[spoiler: Manabu, and unlike the example above it's ''not'' played for laughs. His mother was engaged to another man but had an affair with his father. Then his father abandoned her once the Tanaka family found out. Excluding his grandpa, uncle, Misaki and Mayami, he's treated as an eyesore and a nuisance by everyone in his family. His own mother won't even see him. Worst of all, for the first 15 years of his life nobody even bothered to tell him ''why''.]]
* DarkIsNotEvil: While the principal has a way of turning bad kids into good kids that can only be described as brainwashing and he isn't afraid to beat the crap out of his students (including girls) to enforce rules, he doesn't seem to be all that evil and is genuinely nice to those who follow the rules.
* DatePeepers: After telling Mayami she can't come with them when they go to see {{Film/Avatar}}, Reina and Manabu end up spending most of their date following Mayami after they see her seeing the same movie with some guy they don't know, to make sure he's not a creep.
* DemonicPossession: "The Cursed Black Bat". Manabu manages to stop it with ThePowerOfLove.
* DeusExitMachina: In "The Cursed Black Bat" (26.1), Manabu and the Principal are conveniently absent when trouble starts, though Manabu returns to save the day.
-->'''Hijiri:''' '''''Why now of all times!'''''
* DisappearedDad: Nanami's dad left after she beat him up in pre-school. [[spoiler: They reunited some years later.]]
* DissonantSerenity: Reina pulled [[http://www.batoto.net/read/_/122194/yandere-kanojo_ch42_by_vexed-scans/16 this]] prior to delivering [[GoryDiscretionShot a fitting punishment]].
* DoctorJerk: The school doctor. And he ''knows'' it.
* DoubleStandard: Mayami is a masochist who wants to be beaten up by Reina, but thinks that men who beat up women are the lowest form of life.
** Will also turn sadist on Shiratori from time to time and bully him for amusement.
* DreadfulMusician: Kuroko. She can't move on to the next world till someone recognizes the music she's playing, but she plays so badly it's impossible. [[spoiler:She apparently remembers what it was at the end of her introductory story, but sticks around.]]
* DullSurprise: Manabu's 'Hooray' when Reina is dressed up.
* ElephantInTheLivingRoom: The dynamics of the Tanaka family. Manabu doesn't live with his parents, and doesn't seem to go to any trouble to contact them. He's told Reina that Mayami and his grandfather don't get along, but that seems to have been a lie. There's some kind of a secret there, that the author only sees fit to reveal in parts and pieces.
** On a similar note, Misaki/[[spoiler:Kuroko]]. None of the Tanaka family are [[spoiler:able to see her, although everyone else can.]] Azuma asked Mayami about her condition in an earlier chapter, and Mayami's hair is the same screentone as [[spoiler:Misaki's middle-aged husband.]] Throw in Manabu's feelings of guilt about "not being a good son" and it all leads to one big conclusion and/or one big EpilepticTree to be shot down in hilarious fashion.
*** Shot down, but not hilariously: Misaki is Manabu and Mayami's aunt. Their mother is still around, and [[spoiler:she does her best to push Manabu away in order to forget about his father.]]
** Mayami's past is something of an issue as well. She herself ''really'' doesn't like who she used to be, and Manabu seems to find remembering what she was like painful.
* EvenEvilHasLovedOnes: While not exactly evil, there's no doubt that Ugajin is more deliberately malicious in his actions than any other recurring antagonist in the series. However, he does care for his groupies, and his response to Manabu's hypothetical question in Chapter 56 ([[spoiler:which the latter used as a way to get advice on how to handle his family's situation]]) nets him a minor moment of awesome.
* EvenTheGirlsWantHer: Reina.
** Akira is this, albeit in a [[{{Bifauxnen}} different way]] than Reina.
** Nanami got this in elementary school.
* EveryGirlIsCuterWithHairDecs:
** Gender-flipped: Shiratori has a hair clip in the front of his hair for no particular reason.
** Parodied with the character of Tsukihitsugi, introduced in [[http://www.batoto.net/read/_/7633/yandere-kanojo_ch25.5_by_vexed-scans/2 Chapter 25.1]], who looks like she fell into a pile of hair decs.
* FaceOfAThug: Reina's dad utterly terrifies most people around him because he looks like a gangster, acts gruff and makes sudden, very violent-seeming movements most of the time. The gag is that he's only terrifying because he's actually ''absolutely terrified'' of social situations.
** The school principal, however, ''is'' as terrifying as he looks.
* [[spoiler: FalseFriend: Sumika was this to Nanami when they first met in pre-school, but over time, it became the real thing. Nanami never caught on, even when Sumika confessed it - [[SubvertedTrope as far as she was concerned,]] [[CrowningMomentOfHeartwarming they'd been friends all along.]]]]
* FamilyFriendlyFirearms / NerfArm: The weapons shops sells weapons that look and feel like real weapons, but do no serious or permanent damage. They are only to be used for comedic effect.
* FictionalCounterpart: Mouseland -> {{Disneyland}}.
* ForHalloweenIAmGoingAsMyself: Kuroko loves Halloween because she can go out and trick-or-treat as a BedsheetGhost.
* [[spoiler: FountainOfYouth: Reina in chapter 28 - albeit with a few modifications, because she doesn't look like her childhood photos.]]
* FracturedFairyTale: The Cinderella chapter, with Reina as Cinderella, Manabu as the wizard who helps her, Shiratori as the prince, and Nanami's gang as the stepsisters.
* FragileFlower: [[spoiler:The Principal's wife.]]
** [[spoiler:[[http://www.batoto.net/read/_/7618/yandere-kanojo_ch18_by_vexed-scans/5 Reina]] also had her moments as well.]]
* FriendToAllChildren: Manabu. [[FreudianExcuse It's because]] [[TheWoobie he was lonely as a child.]]
* FriendlessBackground: Manabu, which ends up getting heartbreakingly PlayedForDrama.
* GRatedDrug: Amazake in chapter 31.1. Normally it's either non-alcoholic or has a low amount of alcohol. Reina, under the impression it's safe regardless, puts in too much sake lees, making it a strong booze, and [[MushroomSamba everyone has a crazy moment as a result]].
* GenerationXerox: Reina is shaping up to be just like her mother. [[spoiler:However, she also [[JerkWithAHeartOfGold got some]] NiceGirl traits from her father.]]
* TheGenericGuy: Everybody else has some sort of quirky personality traits, but Hijiri doesn't have much going on besides ShipTease with Shiratori, as well as playing the role of a "normal girl" to contrast Reina with. Lampshaded in her profile: originally, she was intended to be a background character in her initial chapter, then after they got the go-ahead for serialization, she got upgraded to the main cast. Her being the class rep was a complete accident.
* GenreRefugee: A lot of characters seem to have got lost from [[ShoujoGenre contemporary girly romance manga]]. [[HilarityEnsues Not that it's a bad thing]].
* GhostShipping: Of the unrequited variety, considering that the object of Kuroko's affections can't even ''see'' her.
* GirlishPigtails: Mayami and Hijiri both sport these. Tsukihitsugi does too, in 'civvies'; it looks like she also has them in her exorcist outfit, but the hair decs make it hard to tell.
* GoldenSnitch: Mayami pulls this as hostess of a gameshow. Reina, as one of the contestants, is not happy.
** Leads straight to [[spoiler: A CrackDefeat when two guys in the background who admit they're so unimportant they don't even have names, and have not answered a single question right, win. The question? What is the name of the author of [[BreakingTheFourthWall Yandere Kanojo]]?]]
* GoodAngelBadAngel: Reina met them in the chapter where she tried to find out the reason Manabu wears glasses without need.
* GreenEyedMonster: After Shiratori calls Manabu's sister "[[FirstNameBasis Mayami-kun]]," Hijiri goes into a minor HeroicBSOD that's serious enough for her to request that Reina punch her to snap her out of it. Mayami is sharp enough to notice it and assures her that she has no interest in Shiratori while teasing Hijiri about her jealousy.
* GuileHero: [[spoiler:The Principal in chapter 39.1. [[ItMakesSenseInContext "All female students should wear spats,"]] indeed.]]
* HappilyMarried / SickeninglySweethearts: Reina's parents. [[spoiler:Later, we find out that The Principal and his wife are also like this, though they are more subdued.]]
* HarmlessVillain: Nanami and her gang, without a doubt. You might even start wondering if she's even a villain at all, as one of her gang members outright states that she likes to ''help'' people.
** Later, we learn her favourite doll was [[TheHero Red]] [[SuperSentai Ranger]], and that she was 'strong, but kind' when she was younger. A HeroAntagonist, perhaps...?
*** She's certainly a HeroOfAnotherStory.
* HeIsNotMyBoyfriend: Reina wants to preserve her tough image. Manabu is happy to go with the flow.
* HeroicBastard: [[spoiler: Manabu]]
* HeroicSelfDeprecation: Manabu at times. Mostly PlayedForLaughs. [[spoiler:Except things about his ParentalAbandonment.]]
** [[spoiler:Shiratori doesn't readily accept Hijiri's confession, despite liking her, since he's unsure that he will able to eventually love her back. In this case, PlayedForDrama.]]
* HetIsEw: According to Shuuei Mori.
* HiddenDepths: A lot of seemingly {{Jerkass}} characters are actually decent people when the situation calls for it.
** Beneath all the loud bombast and obnoxiousness Shiratori does when trying to pursue his [[UnknownRival "rivalry"]] with Manabu, he's actually a really nice person. Hijiri develops feelings for him after seeing said hidden depths.
** Mayami has shown that she can be pretty perceptive when she wants to be, occasionally being nicknamed "Professor Mayami" by the other characters. That's why it's such a shame that she uses it to try and find new ways to provoke Reina into beating the stuffing out of her. Also, as much as she insults her brother, there's no real malice in it and she goes into [[TranquilFury a stony rage]] if someone hurts him.
** Even characters like [[UnknownRival Nanami]], Sumika and [[TheHunter Tsukihitsugi]] have these moments.
* HoYay / HomoeroticSubtext: Hijiri, Mayami, and Reina determine that the reason Shiratori doesn't show interest in love and dating girls is because he's preoccupied with something else. That something else being Manabu. Make of that what you will.
** It's shown that he's not interested in love because of his upbringing at home (he has dominating sisters). Analyzed by Mayami, no less.[[invoked]]
** Chapter 32 has the girls try to improve Shiratori and Manabu's friendship using KimoDameshi . . . which is usually an anime plot device used for ShipTease and/or invoked by the ShipperOnDeck.
** It goes right back to Shiratori's first appearance in chapter 3. Shiratori and Reina make a bet; if Manabu wins, Shiratori has to eat spaghetti through his nose, while if Shiratori wins, Reina owes him a date. When Reina starts freaking out afterwards, Manabu says he'll go on the date instead.
** In chapter 35, Reina notes Manabu gets obsessed over whatever he targets (in this case, Shiratori).
** In chapter 39.1 Reina outright [[InvokedTrope invokes]] this when she nonchalantly accuses Shiratori and Manabu of flirting with each other.
** [[http://www.batoto.net/read/_/154575/yandere-kanojo_ch47_by_vexed-scans/12 Friend power, indeed.]]
** Chapter 45.5: Shuuei is openly disappointed he couldn't have met Azuma Tanaka when he was younger. Azuma proceeds to put the moves on him.
* HotForTeacher: A-ko falls for Kouichiro after he helps her, and tries to convince him to leave his wife for her. [[ViolentlyProtectiveGirlfriend Three guesses]] [[{{Yandere}} as to how well]] [[CurbStompBattle that works out]].
** Tsukihitsugi develops a crush on the principal in later chapters, and she's [[HeroicBSOD less than happy]] when she finds out about his [[spoiler:(supposed)]] daughter, and [[SerialEscalation much less happy]] when she finds out that said "daughter" [[spoiler:is his ''wife'']].
* HypocriticalHumor: When Reina saw one of her subordinates crying because she saw her boyfriend with another girl, she just told her to go kick their asses. When she sees [[http://www.batoto.net/read/_/7600/yandere-kanojo_ch3.5_by_vexed-scans Manabu with another girl...]]
* IWantMyBelovedToBeHappy: PlayedForLaughs in chapter 29. Ran (Reina's mother) suspects that her husband Kouichirou's odd behavior means he's having an affair (it turns out he's actually hanging out with Manabu's grandfather). The following exchange occurs:
--> '''Reina:''' '''''What was that? Dad is cheating on you!?'''''\\
'''Ran:''' He's not cheating on me!! He fell in love with another woman besides me!!\\
'''Reina:''' Uhh, that's what you would call cheating, isn't it?\\
'''Ran:''' Kouichirou has the right to love whoever he wants, so I'm not going to call it something as bad as cheating!\\
'''Manabu:''' [[LampshadeHanging Whoa, that reasoning of yours is oozing with love...]]
* ImagineSpot: Reina likes to imagine herself being girly or cutesy.
* InWhichATropeIsDescribed: A common format for chapter titles runs "X, that is, something something something."
* IncestSubtext: In an early chapter, Reina mistakes Manabu and Mayami for being NotBloodSiblings, which Mayami lampshades as sounding like something out of an eroge. In later chapters, it's at least strongly implied that this may be the case for Manabu and [[spoiler:Kuroko]], which turns out to sort of be the case: [[spoiler:she's his aunt by marriage]].
** In a WhamLine at the end of chapter 63, Azami, in the middle of a total breakdown, admits to Reina that part of the reason she's so cold towards Manabu is she's afraid of what would happen if she starts seeing his father in him.
* IncrediblyLamePun: The series title.
** Elizadeath.
** Wakako seems to have the name she does just so the author could pun her name into Bakako in the title of the chapter she features in.
* ItAmusedMe: ''Hijiri'', of all people, at one point goes out of her way to antagonize Shiratori for no reason other than it being hilarious.
* ItRunsInTheFamily: Reina gets her {{tsundere}} personality from a fusion of her mom's sweetness/violence and her dad's social awkwardness. Also, her mother's violent side is tempered with her father's kindness.
** Inverted personality-wise with Manabu. His serious personality comes from growing up as his grandfather's straight man. He's been noted to ''look'' quite a bit like him, though.
* JapaneseDelinquents: Reina before falling for Manabu. Her old friends still. Nanami and her gang. Her mom at Reina's age.
* JerkWithAHeartOfGold: Almost everyone who doesn't qualify for NiceGuy.
* KansaiRegionalAccent: Nanami has one so strong that it's practically a character trait.
* KarmaHoudini: This is more or less Sumika's hat. She's too smart to be tricked or made to look bad by the main characters, and since she can't fight, there's no honor in Reina beating her up.
* [[SkirtOverSlacks Kimono Over Boxers]]: [[AllMenArePerverts A crowd of male onlookers]] collectively drops to their knees in grief after Reina denies them a PantyShot, or something even better, this way while celebrating a badminton victory a little too enthusiastically.
* LethalChef: Reina, but Manabu can stomach it with a smile.
** It's not a matter of Reina being a lethal chef, [[OneNoteCook it's more that Reina only knows how to make curry, and applies it to EVERYTHING ELSE.]]
* LockedInARoom: Hijiri and Shiratori get locked in a storage closet. [[GenreSavvy They're quickly rescued, though, since Hijiri told a teacher she'd be working in the closet with the faulty lock.]]
* LoveAtFirstSight: Manabu and Reina mutually fall in love at first sight in the first 4-Koma, allowing a convenient [[AvertedTrope aversion]] of WillTheyOrWontThey.
** Nanami falls for Manabu the first time she manages to get a look at his face.
* LoveEpiphany: [[spoiler:Hijiri in chapter 42.]]
* MayDecemberRomance: Mayami and the Manager have plenty of significant ShipTease moments with each other. Being a first year, she's around fourteen-fifteen; Chapter 25 reveals that he's twenty-six.
* MeaningfulName: The StringyHairedGhostGirl has no actual name, so she gets nicknamed "Kuroko" for her black hair (''kuro'' means black and -''ko'' is a feminine suffix). [[spoiler:[[SubvertedTrope Chapter 41 implies that her real name is Misaki,]] [[OutOfBodyExperience and she's actually still alive, only unconscious.]]]]
* {{Meganekko}}: Tsukihitsugi is this in 'civvies' (she normally wears colored contacts, but the school bans them).
* MenAreStrongWomenArePretty: Reina's a delinquent who gets into fights on a daily basis. Manabu's an honor student with pretty much no athletic tendencies whatsoever. Yet, when they do their FreakyFridayFlip, Reina (in Manabu's body) has to hold back when she hits him to avoid seriously injuring Manabu (in Reina's body). [[JustifiedTrope Possibly justified]] or lampshaded in that getting hit by Reina whenever she gets surprised or flustered has gotten Manabu into much better shape.
* MrExposition: [[LampshadeHanging Lampshaded]] in chapter 5.1. When Shiratori gives a description of the girls and guys having separate swimming times, two background characters [[LeaningOnTheFourthWall comment on his doing so.]]
---> '''Background Character A:''' Oh, what a detailed description
--->'''Background Character B:''' Shiratori is always yelling in a big panel, isn't he?
* MythologyGag: Seen under {{Yandere}} for WhatCouldHaveBeen with Manabu's lil sis? Behold, [[ClingyJealousGirl Tsugumi]] [[BigBrotherAttraction Shiratori]], [[ItMakesSenseInContext Reina's pen pal over a misplaced letter.]]
* NeighborhoodFriendlyGangsters
* NiceCharacterMeanActor / MoodSwinger: [[spoiler:Reina's uncle, Souijiro/Soji.]]
* NiceGuy: Manabu, contrasting him comically with Reina's brash and violent personality.
** Reina's dad is also one, but his ShrinkingViolet status, combined with FaceOfAThug, means he gets mistaken as a mean guy.
** Not to mention Hijiri.
** Actually, every recurring character has shades of this, even guys like [[TheRival Shiratori,]] [[HeroicWannabe Tsukihitsugi]] and [[SternTeacher The Principal.]]
** Sosuke. When he discovers his fiancee is pregnant with another man's child, he opts to continue their engagement. Azuma points out he might be a little ''too'' nice.
* NotSoStoic: Manabu only ever loses his cool when his grandpa is involved, even noting that's probably the only time that happens.
** There's also the time Reina went overboard with dieting and nearly passed out.
* OddFriendship: Manabu's grandfather and Reina's dad have become friends and keep in touch regularly, despite being total opposites in terms of outgoingness.
** Most of the friendships are of this trope (Reina/Hijiri, Reina/Mayami, Manabu/Shiratori, Sumika/Nanami).
* OfficialCouple: Manabu and Reina's relationship is pretty much the entire point of the manga.
* {{Ojou}}: Sumika's the daughter of a CEO.
** [[spoiler: Mayami]], of all people, turns out to live in a BigFancyHouse with numerous servants.
* OlderThanSheLooks: [[spoiler: The Principal's ''wife''. She was so [[{{Moe}} young looking]] and {{adorkable}} that most male students fell for her. Of course, it helps that they ''didn't'' realize she was the Principal's wife.]]
** Nanami. [[spoiler:Deconstructed in chapter 46.1.]]
---> [[spoiler:[[HeroicBSOD Does that means you won't treat me nice anymore now that you know I'm not a little kid? ... Was the only reason you were so nice to me when we first met at the school festival, 'cause you thought I was a little kid?]] [[ShootTheShaggyDog That time at the beach, too.... Everything was all 'cause you thought I was a kid?]] [[HopelessSuitor After you said that stuff at the beach... I told myself I'd try to grow up, get prettier, grow taller than 160 cm... and turn into the most beautiful girl you'd ever seen... but...]] ''[[TearJerker are you saying that even if I do all that, you won't love me?]]'']]
* OneNoteCook: Reina and curry. With a lot of help she made cookies one time.
* OOCIsSeriousBusiness: "JUST SHUT UP AND WATCH IT!!!!" [[spoiler:Done by [[NiceGirl Hijiri]] to [[CannotSpitItOut Shiratori]]. Later it's revealed that she was planning to confess to him ''on national television''.]]
** In chapter 26, Mayami goes on hitting Shiratori for bothering Manabu. [[spoiler:She did it since, apparently, [[IHatePastMe Shiratori reminds her of her past self.]] [[WildMassGuessing She also mentioned that she's unlucky]] [[DysfunctionJunction "to be born in that kind of family".]]]]
** Manabu is usually calm, collected and answers questions without a second thought. [[spoiler: So when he starts dodging Reina's questions about his family[[note]]Going so far as to ''jump out of the boat that they were in''[[/note]] in Chapter 57, you know that the Tanaka family must be seriously screwed up.]]
* OpenSecret: By about four chapters in most students realize they're a couple; they're just smart enough not to say anything.
* {{Otaku}}: The Manager. He does know when to turn his enthusiasm off, if necessary.
* PaintingTheMedium: Mayami uses square speech bubbles to imitate narration bubbles and the others acknowledge that because of this they have to follow what she said.
* PaperFanOfDoom: Manabu buys one of these when Reina takes him to a weapons shop.
* ParentalAbandonment: [[spoiler: Manabu.]]
** Reina's grandparents disowned Ran.
* ThePiratesWhoDontDoAnything: Reina's delinquent gang. They're in school every day, don't drink, smoke, or do drugs, and the only gang fight seen in the comics takes place with a felt-tip pen. Naturally enough, this gets lampshaded.
** RuleAbidingRebel: In chapter 42, Reina reveals that she didn't complain much when asked to clean graffiti that she drew herself (which was a lot in middle school).
** Then Reina goes and lays a full-on smackdown in 27.1.
* PitbullDatesPuppy: Our OfficialCouple, [[GenerationXerox as well as Reina's parents]]. Later, it's revealed that this is the case with the principal and his wife as well, albeit gender-flipped.
* PokeThePoodle: Subverted with Daikichi Ugajin. While his abuse of his Student Council power is just so he can do things, such as flipping up girls' skirts without the fear of retribution and taking all the male students' porn to make a porn room for public access, they're treated as very serious threats by Reina and her friends.
* {{Polyamory}}: Ugajin's groupies seem to have no problem with sharing him, or the fact that he's pursuing Reina.
* PostKissCatatonia: As mentioned under ShipTease below, a kiss on the ''cheek'' from [=Drunk!Hijiri=] was enough to cause this in Shiratori.
* ThePromise: [[spoiler: Nanami and Sumika promised to go to high school together back when the two were in grade school.]] It's a minor heartwarming moment that they made good on the promise, even though some aspects of it ([[spoiler:such as the fact that Nanami was exactly the same height as she was in grade school when they reunited]]) were played for laughs.
* PurelyAestheticGlasses: Manabu's glasses are just for show.
** A whole chapter is actually devoted to exploring the mystery of Manabu's glasses. Long story short, [[spoiler:they're basically a MementoMacGuffin from his grandfather.]]
* RecursiveCanon: The manga and author exist in the manga's universe. None of the main characters know them.
* RefugeInAudacity: What does Reina do, when after she demands to talk with Manabu's mom while brandishing a baseball bat, his uncle threatens to [[MundaneSolution call the cops on her]]? Why, kidnap their father, Azuma, and threaten to bash his head in with [[WhenAllYouHaveIsAHammer a baseball bat]] if they refuse! [[spoiler: The kidnapping itself is most likely staged, considering [[NiceGuy Azusa]] and [[JerkWithAHeartOfGold Reina]]'s characters. That doesn't stop her from hitting Grandpa with a bat when Manabu's uncle tries to call her bluff.]]
* RelationshipUpgrade: In a roundabout way, chapter 27 has Hijiri and Shiratori acknowledging each other's mutual attraction and going out on a date. Due to their inexperience with such things, though, they don't actually think it was a date or that it makes them a couple.
** Chapter 46 sees [[spoiler:Hijiri]] finally confessing her love. On national television, no less. [[spoiler: In chapter 48, they finally become an OfficialCouple.]]
* TheResenter: This was a large part of the motivation for Shiratori's rivalry with Manabu; he resented Manabu for not being the least bit curious about him or the things that concerned him (i.e. test score rank).
* RetiredBadass: Reina's mom. "Don't worry, if anyone were to badmouth you, I'd show them what it was like when your mom was feared as a human weapon!"
** The flashback chapters to how she and Reina's dad fell in love somehow make her out to be even more violent, feared, and hot-tempered than Reina. There's implications she may have even ''killed'' people.
* SavvyGuyEnergeticGirl: Our OfficialCouple, of course. Exaggerated or deconstructed for parody in the case of Reina's parents, with each one being on the other end of the spectrum.
** Interesting case with [[spoiler:Shiratori and Hijiri.]] The problem is that [[spoiler: Shiratori is [[SeriousBusiness too]] [[WrongGenreSavvy savvy]] [[CannotSpitItOut for his]] [[HeroicSelfDeprecation own good,]] to the point that Hijiri had to take a more active role in the relationship, despite her NiceGirl status.]]
* SecretRelationship: At least initially (see {{Tsundere}} further down), but as the series goes on it becomes more of an OpenSecret, if even that, especially with Manabu and Reina not bothering to hide it in front of any named characters, who all know about it.
* SeriousBusiness: [[http://www.batoto.net/read/_/7597/yandere-kanojo_ch2_by_c-k/7 Bloomers.]]
** Shiratori always takes ''everything'' with such high fervor. Sometimes it's [[{{Adorkable}} endearing,]] sometimes it's [[TheComicallySerious funny,]] sometimes [[TheResenter it's]] [[HeroicSelfDeprecation sad.]]
* SexySantaDress: Reina's employer outfits his female employees with this at Christmas.
* SheCleansUpNicely: Reina and Manabu have a mutual moment of this when they meet up wearing yukata at the festival. Downplayed as they thought the other was attractive before hand and furthermore, it has been established through the comments of Manabu's grandfather that Reina does not need to "clean up" for the people around her to notice that she is attractive.
** [[spoiler:Hijiri was shoved into a makeover show in Chapters 45-46.]]
* ShipTease: Hijiri and Shiratori, [[HeartwarmingMoment sometimes Awwsome]], [[PlayedForLaughs sometimes humorous]]. [[http://www.batoto.net/read/_/7631/yandere-kanojo_ch24.5_by_vexed-scans/8 This example manages to be both]].
** Chapter 18 has Hijiri refuse confession from another guy after Shiratori says "Don't do it." [[ItMakesSenseInContext He's talking about a reference book Hijiri used.]]
** Chapter 27 is focused entirely on their RelationshipUpgrade. Not into a full couple, but pretty damn close.
** Taken even further in Chapter 31, an entire chapter that kicks off with Hijiri admitting that she likes Shiratori. We'll see if this leads anywhere.
** Topped by 4Koma chapter 31.1, where [[http://www.batoto.net/read/_/26268/yandere-kanojo_ch31.5_by_vexed-scans/12 Drunk!Hijiri made dirty jokes and kissed him on the cheek]], [[LaserGuidedAmnesia but doesn't remember anything when she's sober]].
** This culminates in Chapter 46, when she [[spoiler:confesses her love on national television]], flooring everyone.
** Mayami and the Manager; their exact relationship is ambiguous, but it does have romantic overtones sometimes, such as the fact that they establish the cafe together. The most significant ShipTease of them so far is Chapter 39, a Manager-centric chapter. The title page has the statement "give flowers to your loved one" and features a smiling Mayami getting a bouquet.
** In Chapter 45, Mayami kept her hair long for the sake of the Manager. Then in 45.1 she's very much conflicted between keeping her GenkiGirl (for the Manager) or YamatoNadeshiko (for her Grandpa) persona, and the Manager decides to go along with the latter. When the Manager asks if he's the grandad [[FatherIWantToMarryMyBrother Mayami had a crush on when she was little]], Mayami looks away while blushing and says there's someone else she likes.
* ShooOutTheClowns: [[spoiler: Kuroko's/Misaki's passing in Chapter 54 serves as the beginning to finding out why the Tanaka family is so screwed up.]]
* ShootTheHostage: A ShowWithinAShow has the magical girl heroine [[http://www.batoto.net/read/_/7619/yandere-kanojo_ch18.5_by_vexed-scans/12 kill hostages just to get to the villain]]. She even has a specific hostage-killer attack.
* ShoutOut: See [[ShoutOut/YandereKanojo here]]
* ShowWithinAShow: "Princess Mamii", a MagicalGirlWarrior anime.
* ShrinkingViolet: Rare male example, Reina's dad. He got it worse than ''[[KatawaShoujo Hanako]]''!
** Also deconstructed, since his withdrawnness makes him unapproachable by his students, so he's mistaken for a [[PsychologistTeacher Psychologist]] SadistTeacher. [[NiceGuy (He's anything but that.)]]
* SitcomArchNemesis: Kuroko is one to Tsukihitsugi, much to the latter's annoyance.
* SlaveToPR: Reina really wants to keep her image as a delinquent.
* SmarterThanYouLook: Mayami and Manager. [[PairTheSmartOnes No wonder]] [[BirdsOfAFeather they got some]] ShipTease.
* SmokingIsCool: Manabu's grandfather smokes, and is as cool as they come.
* SpoofAesop: Beaten into the ground.
* SternTeacher: The Principal. Borderline SadistTeacher if not for the fact that he treats students who follow rules, including "redeemed" delinquents, with utmost respect.
** In chapter 36.1, it is shown that he's quite a ReasonableAuthorityFigure, forgiving Tsukihitsugi for breaking his vase (which is a present from his students) since she apologizes and the vase is fixed (though he still hits Reina for taking supplies from his desk without permission). And from his story, it seems that he also likes to help students who have constructive hobbies.
** He also averts the expected AdultsAreUseless trope in chapter 39.1, where [[spoiler: he sees through Daikichi Ugajin's plan to see the panties of the female students, and [[CrowningMomentOfAwesome neutralizes it by exploiting a loophole, outwitting the normally cool and calculating Ugajin.]]]]
* TheStoic: Manabu's defining trait is his ability to take Reina's {{Megaton Punch}}es, amazingly spicy cooking, Shiratori's persistent attempts to conduct some sort of rivalry, and pretty much everything else that happens to him in stride. Reina inwardly complains it makes him hard to read, but then again a less patient guy probably wouldn't put up [[{{Tsundere}} with the abuse she dished out earlier in the series]].
* TheStoolPigeon: Kuroko's "job" at the school, as revealed in chapter 41.
---> '''Kuroko:''' He [the principal] gives me 10-100 yen each time I tell him about a student who was late, skipped class, cheated on a test, ate lunch in class, or broke any of the other school rules.
* StringyHairedGhostGirl: Kuroko's a comical version.
* SugarAndIcePersonality: Sumika's other hat: she's mostly cool, snarky and insulting, but can have reasonable conversations with her opponents, and absolutely gushes over Nanami.
* SuperDrowningSkills: Reina swims like a rock. [[spoiler:Turns out Hijiri does too.]]
* SupportingHarem: Kuroko and Nanami are both attracted to Manabu. Of course, one of them's [[spoiler:supposedly]] ''dead'', and he sees the other one as a child despite them being the same age...
** Daikichi Ugajin's groupies are this in a literal sense.
* ThatCameOutWrong: Reina and Hijiri, while discussing Hijiri's crush (or, rather, lack thereof) in home ec:
-->'''Hijiri:''' "I must say, you look really cute when you're working hard...in fact, I'd say I'd rather love Reina than some guy. *beat* O-OF COURSE I DIDN'T MEAN IT IN A WEIRD WAY! I MEANT AS FRIENDS!"
* ThemeNaming: Reina's flunkies are named Eiko & Biko ("Girl A" and "Girl B"), fitting their largely unimportant to the plot status.
* TokenMiniMoe: Nanami, though she's also a case of OlderThanTheyLook (her age is given as 16). It works against her anyway since Manabu treats her crush on him as a PrecociousCrush, not to be taken seriously.
* TomboyAndGirlyGirl: Reina and Hijiri.
** Nanami and Sumika.
* TooKinkyToTorture: Physical retaliation by Reina to any of Mayami's antics doesn't work because it's ''exactly what she wants''.
** She even calls Reina "Mistress".
* ToughLove: The Principal is a firm believer of this, especially toward delinquents. Not that he's totally unreasonable, mind you.
* TranquilFury: There's no better way to describe Manabu's reaction to Wakako badmouthing Reina behind her back.
* {{Transsexual}}: When several of the students find an old yearbook photo of Sally, the school's janitor, they see her as a male-bodied student in a boy's uniform. Sally laughs it off and says that back then she "hadn't blossomed as a woman yet".
* {{Tsundere}}: Oddly enough, this applies to Reina. She quickly gets shy and tsuntsun with her boyfriend, but wants to hide the whole relationship to preserve her reputation.
** Reina's mother as well; that's where she gets it from.
** Shiratori seems to be platonically tsundere for Manabu, wanting to be his friend instead of significant other.
** Nanami gets a platonically tsundere moment over Reina in 27.1.
** After Manabu saves Reina and Chibita from cats, Reina worries about his injuries. Manabu says [[OldSchoolChivalry it's better than getting a lady's face injured.]] Reina's response to that is... interesting.
---> '''Reina''': Geeeez, you idiot! Moron!!! You're so smug! Trying to act like some cool knight! [[KnightInShiningArmor You prince on a white horse!!]] [[FreudianSlip You glasses-wearing stud!!!]]
* TwoLinesNoWaiting: Is actually two different titles; a web published one (the 4-koma) and a print one (the conventional one). Since most scanlation sites just put the story up in order, it leads to the two-part stories being cut off in between.
* TyrantTakesTheHelm: Daikichi Ugajin and his groupies in Chapter 38.1.
* UglyGuyHotWife: Reina's parents. Justified; having the FaceOfAThug is what attracted her to him in the first place.
* UnknownRival: Shiratori - no matter how much better his grades are than Manabu's, no matter how obnoxious and insulting he is, Manabu and eventually Reina barely pay him any mind.
** Nanami and her gang definitely count, as Reina just sees her as a pest rather than an actual threat.
* TheUnsmile: In chapter 22 Hijiri's face freezes into a smile when she becomes jealous about Shiratori calling Mayami by her [[FirstNameBasis first name]].
* VillainWithGoodPublicity: Daikichi Ugajin, much to the dismay of Reina and [[TranquilFury Manabu]].
* ViolentlyProtectiveGirlfriend: Reina. She's pretty protective of her friends generally, but god help you if you mess with Manabu. [[TheStoic Even if Manabu himself doesn't care.]]
** Like many of Reina's traits, it comes from her mother. In one story, Ran ''crucifies'' a solicitor for wasting Kouichirou's time while they're on a date, while in another, she threatens his entire class if they cause him trouble.
* WeWantOurJerkBack: Chapter 47.1 in a nutshell.
* WhatDoesSheSeeInHim: Manabu's a relatively ordinary-looking guy. Reina seems to think he's on the male supermodel/"legendary man-whore" end of the spectrum.
** [[LampshadeHanging Lampshaded]], [[http://www.batoto.net/read/_/7618/yandere-kanojo_ch18_by_vexed-scans/7 of course.]]
* [[WhenSheSmiles When He Smiles]]: Reina's dad smiled once, and everyone was [[http://www.batoto.net/read/_/7616/yandere-kanojo_ch17_by_vexed-scans/11 surprised.]]
** During the high school days of Reina's parents, Ran (Reina's mom) fainted after Kouichirou (Reina's dad) smiled at her. The effect of the smile was so profound it made her deredere side the dominant one. Note that Ran was one of the most feared delinquents in her neighborhood during her time. [[LampshadeHanging "That line short-circuited her"]] indeed.
** Even Reina herself qualifies, demonstrated [[http://www.mangahere.com/manga/yandere_kanojo/v01/c003/14.html here.]]
* WholeEpisodeFlashback: Reina's parents' first meeting, and Sumika and Nanami's first meeting, both get two chapters.
** Hiromichi's origin in chapter 39.
* {{Yandere}}: [[SubvertedTrope Subverted]], when you consider the title and Reina's personality. An omake reveals that [[WhatCouldHaveBeen Mayami was originally supposed to be a murderously jealous yandere little sister]] before the author decided otherwise.
** Ran, on the other hand, plays this trope straight in chapter 37.
* {{Yonkoma}}
* YouGottaHaveBlueHair: Hijiri (dark green) and Nanami (light blue).
* ZettaiRyouiki: Reina on one of her dates.
