History Manga / NanaToKaoru

* {{Meganekko}}

* RidiculouslyCuteCritter: Hiro the puppy from the "Dog" chapters.

* BatmanGambit: Ryoko knows Nana is both a tsundere and a clingy jealous girl. So to get Nana to join in the breather, she makes a lot of noise like it's already started and he's hurting her. Sure enough...

* OnlySixFaces: Nana shares a lot of features with the other female leads in Amazume's series.

Later entires take place in slight AnachronicOrder. To avoid RememberTheNewGuy, Nana to Kaoru is best enjoyed in the following chronological order:

Now with a shiny [[CharacterSheets Character Page]], please [[Characters/NanaToKaoru contribute]].

* BettyAndVeronica: In the mind of the class president's sister in regards to Kaoru, with Nana as Betty and Ryoko as Veronica.
* {{Bifauxnen}}: Taichi starts out this way. Though later chapters make it more clearly she is in fact, a girl.
* {{Big Damn Hero|es}}: [[spoiler:Kaoru at the start of chapter 38/YA 16 [[JustInTime saves Ryoko]] from a [[CatchAFallingStar nasty fall]]... by using his own body [[ImOkay to cushion the impact]].]]
* BigNo: Nana does this often to Kaouru's BDSM related requests. Just as often, she goes along with them anyway.

* TheBet: Nana and Ryoko are about to race against each other at a major track and field event. Having spoken to Kaoru beforehand and knowing he is preparing a very big breather, Ryoko proposes a wager to Nana: The winner of the race gets to receive the breather from Kaoru. When the two fiercely run shoulder to shoulder to claim the inner lane, Ryoko slips and collides into Nana, causing both of them to fall and leaving the winner of the two indeterminate. [[spoiler: Kaoru ends up giving the breather to both of them together.]]
* TheBigDamnKiss: [[spoiler: Nana and Kaoru share their first kiss near the end of ''Black Label'' while Nana is bound and hanging from the ceiling.]]

* HowWeGotHere: ''Black Label'' opens with Kaoru and Nana watching [[spoiler: a topless and nearly naked Tachibana being suspended by ropes from the ceiling]] - a ''significantly'' more intense and sexual breather than anything Kaoru and Nana have experienced thus far - and Nana clutching Kaoru's hand in a combination of excitement, fascination, and terror. The story immediately rewinds to several days beforehand and the two receiving invitations from their mentors in bondage to a visit in the countryside.

* BigBraToFill: The live-action Nana is smaller in both bust and height.

* HowWeGotHere: ''Black Label'' opens with Kaoru and Nana watching [[spoiler: a topless and nearly naked Tachibana being hung from the ceiling]] - a ''significantly'' more intense and sexual breather than anything Kaoru and Nana have experienced thus far - and Nana clutching Kaoru's hand in a combination of excitement, fascination, and terror. The story immediately rewinds to several days beforehand and the two receiving invitations from their mentors in bondage to a visit in the countryside.

* AccidentalKiss / SacredFirstKiss: ''[[KissingDiscretionShot Probably]]''. Even Nana and Kaoru aren't sure if it happened or not. It's not actually shown whether or not it actually happened, but according to his following actions in the play, Kaoru seems quite sure that it has; Nana is only shown to touch lips afterwards. But as the end of chapter notes pointed out, [[spoiler:the potential kiss]] wasn't the big movement in their relationship, it was [[spoiler:''Nana realizing she wouldn't have minded kissing Kaoru'']].

** FirstKiss
** HeldGaze

This is the beginning of ''Nana to Kaoru'', a 156-issue {{Ecchi}} manga by Ryuta Amazume. It chronicles Nana and Kaoru's adventures in BDSM, from erotic posing and leash-wearing to bondage and blindfold play, and more. It isn't subtitled ''Nana and Kaoru's S&M Diary'' for nothing.

* RealityEnsues: Turns out that being bound hand and foot in a tight leather outfit without a zipper or precautions for communicating, when you're technically not supposed to be talking, will lead to some trouble.

* AllWomenAreDomsAllMenAreSubs: Averted with [[spoiler:Mitsuko]], who is apparently a long-time submissive.

** Then in chapter Chapter 117: [[spoiler:Tachi nearly lets one out, and in chapter 118 discovers Kaoru will never be with her because he loves Nana too much]].
* AnimalMotifs: Tachi plays mischievous, disobedient kitty cat to Nana's obedient and loyal puppy dog. This gets rather ''explicit'' in chapters 68-70.

* BatmanGambit: Tachi knows Nana is both a tsundere and a clingy jealous girl. So to get Nana to join in the breather, she makes a lot of noise like it's already started and he's hurting her. Sure enough...

* BettyAndVeronica: In the mind of the class president's sister in regards to Kaoru, with Nana as Betty and Tachi as Veronica.

* {{Big Damn Hero|es}}: [[spoiler:Kaoru at the start of chapter 38/YA 16 [[JustInTime saves Tachi]] from a [[CatchAFallingStar nasty fall]]... by using his own body [[ImOkay to cushion the impact]].]]

* {{Blackmail}}: Tachi gets a second "breather" from Kaoru by threatening to tell Nana how much work he puts into their sessions, which would show Nana how deeply Kaoru really feels for her.

* ChekhovsSkill: Kaoru's running becomes really important later on when he has to take a DivingSave to protect Tachi, long after everyone's forgotten about it. He's not even winded by the run (although [[NotTheFallThatKillsYou his shoulder is pretty banged up]] from the fall) while his unknown rival, the student council president, is openly exhausted and ''couldn't keep up''. Considering the president is an all around perfect bishonen, and Kaoru is, well, [[{{Gonk}} not]]... [[CharacterDevelopment character]] isn't the [[TookALevelInBadass only]] thing that Kaoru is developing.

** One example involved Kaoru acting as if he left Nana and Tachi, bound up alone in his room for hours. But he carefully watched the whole scene from a window ready to jump into action if anything went wrong. It's worth noting that he was waiting outside in winter weather, which was cold enough to make him sick.

* CuffsOffRubWrists: Averted, except for Tachi's initial outburst; she complains about her limbs being numb after Kaoru unties her.

* DivingSave: In Chapter 37, Tachi accidentally falls down a ledge but lucky for her Kaoru was there to break her fall. And we really do mean ''break'' her fall.

* DysfunctionJunction: Between Nana, Tachi and Kaoru; We find a host of personal issues that cause them all to be alone and isolated. With Kaoru, it's a massive inferiority complex and lack of self-esteem. With Nana and Tachi, it comes from their motivation to over-achieve which is, in part, a product of their environment.

* {{Farce}}: "The Crepe Truck On The Hill" arc, where a single misunderstanding leads to Tachi and Kaoru chasing after Nana to protect her modesty.

** Nana and Kaoru actually are FWB with Tachi. Still non-sexual.

** Tachi to the well endowed President's sister.

** Tachi as well, with her sporty attitude.

* GreenEyedMonster: Nana upon seeing Tachi tied up (tighter than she had been).

** Kaoru and Tachi, though Kaoru only becomes distressed about it after finding out that [[ViewerGenderConfusion Tachi's a girl]].

* LoveYouAndEverybody: Tachi says she loves Kaoru to Nana, who, while she wouldn't recognise love if it whacked her upside the head with a rose-covered hammer, still blushes like mad or becomes jealous whenever anyone else trespasses on her feelings towards Kaoru. Tachi backsteps quickly to add "as a friend!"

* MaleGaze: Apart from the specific instances (see Fanservice), Nana almost always takes center stage with a three-quarters or full-body shot during the 'breathers'. Tachi too.

** Meanwhile, both their friends pick up on things fairly quickly. Tachi appears to be wavering between wanting to steal Kaoru for herself and wanting to help get them together; Nana's friend in the student council immediately warns her brother about the [[ObliviousToLove deeper meaning]] of her words.

* PoorCommunicationKills: Nana mistakes Tachi as being her Rival in a love triangle when in reality she's Kaoru's SecretKeeper. What secret? [[spoiler:He's in love with Nana.]] Understandably, it's a bit hard to explain this to Nana... But Tachi also is a bit sweet on Kaoru, too, and is starting to hesitate when doing things that might bring them closer together.
** Specifically, the entire track day is one long string of misunderstandings on the three's parts. Nana keeps seeing Tachi with Kaoru, not realizing Tachi is basically dragging him along to cheer Nana (and herself) on, sees the lunchbox he brought, not realizing it was for Tachi and Nana (mostly Nana), not just Tachi, Kaoru mistakenly thinks that Tachi is the one at his door harassing him for a lunchbox when it was really Nana (and he's too embarrassed to apologize), etc etc.

* PottyEmergency: Tachi during her first "breather," leading to...
* PottyFailure: ...Tachi at the end of her first "breather."

* TheRival: Tachi to Nana. Not that Nana cares.
* RunningGag: [[{{Slapstick}} Nana hitting or throwing something at Kaoru]], and Tachi grappling Kaoru against his will.

** Both Nana and Kaoru keep their "breathers" secret from others (indeed, it's part of the thrill). Tachi has also gotten in on it now, and agreed to keep it a secret.

* SwappedRoles: When Tachi stops a younger student from finding out about the "breathers", she forces Kaoru to teach her about administering breathers (or rather, carrot and stick method). She settles on trying to give ''him'' a breather, along with Mitsuko as a guide. [[spoiler:It doesn't work. Kaoru does submit a bit, but refuses to become complacent, and insists he's Nana's Dom, and no one's sub.]]

** Tachi has this habit of always play around with Kaoru in an teasing and[=/=]or [[TheGadfly gadfly]] manner when ever they meet.

* {{Tomboy}}: The very athletic and boyish looking Tachi.
* TomboyAndGirlyGirl: Tachi and Nana respectively, although Tachi is more obviously feminine during the breathers.

** Tachi, Kaoru and Nana are in a romantic Type 5 - Kaoru's infatuated with Nana while Tachi's developed a crush on Kaoru. What's preventing a traditional type 4 in Black Label is whether Nana can work out [[WhatIsThisFeeling what her growing affections for Kaoru mean]].

* NotSoDifferent: On close examination, Nana is almost as isolated as Kaoru.

** [[spoiler:Then Kaoru comes home that very same day to find Nana in his room, [[NotSoDifferent excitedly looking at her picture which she pasted onto the head of a model in his S&M magazine]].]]

* MasculineGirlFeminineBoy: Played with but ultimately strongly averted. Kaoru is short, uninterested in sports and academics, has no real professional aspirations, prefers to blend into the crowd in public, but is an excellent cook and very skilled at sewing and other craftwork. Nana is tall, athletic, an outstanding student with very high career prospects and plenty of public leadership positions, yet is a hopeless cook and despite (or perhaps because of) her incredible beauty, knows almost nothing about cosmetics and make-up. But beneath these traits, Kaoru and Nana share an intense longing to respectively fulfill the masculine and feminine roles, and to be loved by a partner who recognizes and values them respectively as a man and a woman. The most prominent conflict of the story is Kaoru's struggle to overcome his self-doubt and self-hatred and accept his worthiness to stand by Nana's side as a man and a dom.

* [[ChekhovsGun Chekhov's Boobs]]: In Volume 9 Chapter 64 [[spoiler:before the 3000m race we see Nana's main opponent staring and thinking to herself "damn her and her huge breasts", at the end of the race it would have been a dead heat except for Nana's larger bust getting to the tape first]]

* {{Adorkable}}: Kaoru.

* JerkassFacade: Kaoru really plays up his sleazy domination role with Nana, although she knows he isn't really like that.

* HelloNurse: Subverted with Nana. Yes, she's gorgeous (in line with the trope), but her imperious manner scares people off.
* HiddenEyes

Interestingly, a sequel of sorts called ''Black Label'' chronicles Nana and Kaoru's experience during their summer vacation after graduating. Though it's set 8 months from the comic proper, was published side by side with the original manga. An {{interquel}} subtitled ''An oath written between S and M'' was released on November 11, 2018 for the same magazine.

* {{Kuudere}}: Kaoru in his "Master" persona.
