History Manga / KoiKaze

* {{Bishounen}}: Somewhat hilariously subverted. It's shown that before meeting her brother for real Nanoka envisioned him idealistically as being kind, helpful, and very much a pretty boy. While the first two eventually are shown to be the case as Koshiro grows closer to her, a pretty boy he is not. Despite Nanoka fostering romantic feelings for him, she even once muses that he doesn't really fit her idea of 'good-looking'.

* FirstEpisodeTwist: Koshiro and Nanoka are only revealed to be siblings at the end of the first episode.

* SexyDiscretionShot: Used a few times, as the series is designed to portray the situation realistically but isn't in it at all for {{fanservice}}. Koshiro is in a few scenes heavily implied to be masturbating (one of which he later confirms in a guilt-ridden internal dialogue), and eventually he and Nanoka give in to having sex with each other, but the audience never gets shown anything graphic.

* ADateWithRosiePalms: Koshiro is jarringly and explicitly shown to engage in this on impulse due to his escalating feelings for Nanoka. It serves as a strong point of guilt for him, and he feels very out of control after the fact.

* ChristmasCake: Koshiro's family and coworkers wonder why a guy his age isn't married yet.

''Koi Kaze'' by Motoi Yoshida started out as a manga series which then got adapted into an anime series in 2004 and immediately received a lot of attention for its harrowing and realistic examination of sibling incest. The painful and guilt-ridden romance between Koshiro and Nanoka is credibly full of angst and BelligerentSexualTension as the two struggle against their desires, refreshingly devoid of the blithe disregard for social mores and {{fanservice}} most {{shonen}} series on similar subjects tend to have.

* BittersweetEnding: At the end of the anime, [[spoiler:Koshiro and Nanoka are together and happy, but there is unmistakable symbolism that, at the very least, they are still facing a very difficult time to come]]. The makers of the anime obviously wanted to make a point here.
** [[spoiler:The manga has some foreboding symbolism in the chapters leading up to it, but ends on a more positive tone, with Koshiro and Nanoka contemplating the inevitable challenges ahead (symbolized by the park where they "met" on the verge of closing) with open eyes and resolving to stick things out anyway]].

* BrotherSisterIncest: Goes without saying. This series also thoroughly [[{{Deconstruction}} deconstructs]] the usual flippant portrayals of this trope found in other series.
** It's also {{justified|Trope}} and something of a {{reconstruction}} too, as it presents a situation where the UsefulNotes/WestermarckEffect doesn't come into play.

* AuthorAppeal: The manga could only have been drawn by someone who knows how to do technical drawings because it looks like it was drawn in the exact same way that Architects and Engineers used to do design drawings--ink on linen--before any shortcuts were available. It really seems like the artist wanted to show off as many extreme high and low perspective angles as she possibly could, given the number that show up in the manga.
** It's not the high and low angles. It's the near complete lack of greyscale and how she did shading that screams of "I'm a professionally trained draftsperson" in ways that ''only'' someone who is professionaly trained and who has looked at ink-on-linen design drawings would even notice.

* DrivenToSuicide: [[spoiler:Nanoka at one point suggests committing lovers' suicide, but Koshiro objects. It seemed intended not to be taken too seriously, but her reason that it would much easier than trying to figure out their relationship implies she was at least half-serious.]]
** [[spoiler:Koshiro not replying to that suggestion immediately implies that he was also seriously considering it.]]

* HugeGuyTinyGirl: Koshiro's a big guy. Tall, heavy set. Nanoka, though almost 18 by the end of the series, is still tiny. He's well over a head taller than her.
** A bit less pronounced in the manga, since Koshiro is slimmer there.

* PeriodPiece: This series was written in 2001, but appears to be set a decade earlier, as seen with the use of sport uniforms and the lack of cellphones or the internet.

** It's not the high and low angles. It's the near complete lack of greyscale and how she did shading that screams of "I'm a professionally trained draftsperson" in ways that ''only'' someone who is professionaly trained and who has looked at ink-on-linen design drawings [[GeniusBonus would even notice]].

* ArtistsAreNotArchitects: Completely subverted by the manga.

** It's also {{justified}} and something of a {{reconstruction}} too, as it presents a situation where the [[UsefulNotes/WestermarckEffect Westermarck Effect]] doesn't come into play.

* AgeGapRomance: There is an age difference of ''twelve years'' between Koshiro and Nanoka.

** The anime is, with a few exceptions, comprised entirely of events from the manga, but it compresses the two-year period encompassed in the manga (three springs) to one year (two springs). Several of the largely standalone storylines were also cut out to account for the much shorter time frame. Also, oddly, the events of the manga's second chapter were made into an unaired episode 8 of the anime, later restored to the DVD release.

* FirstEpisodeSpoiler: Koshiro and Nanoka are only revealed to be siblings at the end of the first episode.

* SchoolSportUniform: Nanoka and her classmates wear these during gym class. Notably, it's not played for fanservice, but as one of the details that date this series to the nineties (this gym attire was just falling out of use around the time the series takes place), along with the level of technology (for instance, cell phones and the internet are not around).

** There's also [[http://en.wikipedia.org/wiki/Genetic_sexual_attraction Genetic Sexual Attraction]] to explain why they have such strong feelings towards each other.

After his girlfriend dumps him for someone else, 27 year old Koshiro has a chance encounter in the subway with Nanoka, a 15-year-old high school girl. He later meets her again at the entrance to an amusement park and since he has just been given two free tickets to it, he invites her to go with him. Each being rather depressed over the end of a relationship, they immediately feel some emotional connection across their age difference as the afternoon progresses.

On leaving the park, they suddenly discover that they are brother and sister when they both recognize and greet their father as he's arriving. This comes as quite a shock, since they haven't seen each other since their parents got a divorce with split custody some 10 years ago. Moreover, Nanoka is now moving in with her father and brother since their house is much closer to the high school she's attending. Against their better judgment, the first spark of mutual attraction slowly ignites into something deeper and more powerful as time progresses, especially since Nanoka develops a huge big brother complex and she is not deterred in the least by Koshiro's boorish and unsociable nature.

* ArrangedMarriage: Koshiro works in an ''omiai'' (dating arrangement) office. He even faces the possibility of having one of these dates at some point. [[spoiler: He refuses]].

* EarnYourHappyEnding: [[spoiler: What Koshiro and Nanoka are still striving to do by the end.]]

* HiddenHeartOfGold: What Nanoka thinks Koshiro has. [[spoiler: She's not wrong, at least where she's concerned.]]

* IntertwinedFingers: Koshiro and Nanoka hold hands like this on the train [[spoiler: after finally becoming a couple.]]
* InvulnerableKnuckles: Averted - In the manga [[spoiler: after Koshiro asks Chidori to start dating, she punches him in the face. Two pages later, it is shown that her knuckles are hurt as much as Koshiro's face.]]
* JerkAss: Koshiro for the most part, until [[spoiler: he and Nanoka decide to hell with everyone else, they will be together]].
* LetsWaitAWhile: In the manga (but not the anime) [[spoiler: Koshiro and Nanoka make a point of not immediately having sex after finally entering a relationship, and several months pass before they get intimate that way.]]

* LoveLetter: Nanoka receives one from a boy at her school. [[spoiler: She turns him down.]]
* LuminescentBlush: This is more evident in the manga which gives this to almost everyone, but damn you really don't expect to see a bulky guy like Koshiro blush as hard or as often as he does.
* ModestyBedsheet: The penultimate episode of the anime has a completely naked Nanoka covering herself with a bedsheet [[spoiler: after her first time having sex with Koshiro.]]

* AdaptationDistillation: The anime is, with a few exceptions, comprised entirely of events from the manga, but it compresses the two-year period encompassed in the manga (three springs) to one year (two springs). Several of the largely standalone storylines were also cut out to account for the much shorter time frame. Also, oddly, the events of the manga's second chapter were made into an unaired episode 8 of the anime, later restored to the DVD release.
** PragmaticAdaptation: While the anime took almost all of its major plot points from the source material, they were shuffled around to better fit the anime format - some events from early in the manga happened quite late in the anime, and certain scenes were transposed into happening during different storylines or settings, which leads to those changed events having a different context because of how different the relationship between Koshiro and Nanoka is when they happen.
