'''Nitroplus Co., Ltd.''' (nitro+/Nitro Plus before the 2008 rebranding) is a Japanese game company specializing in {{Eroge}} and {{Visual Novel}}s. Its works are almost invariably [[DarkerAndEdgier dark in tone]], with an abundance of {{Eldritch Abomination}}s, horror, rape, [[{{Gorn}} gore]] and violence.

Their first release was 2000's ''VisualNovel/PhantomOfInferno'', also was main writer Gen Urobuchi's first work with the company. Subsequent games such as 2003's ''VisualNovel/SayaNoUta'' and 2008's ''VisualNovel/ChaosHead'' garnered enough acclaim for the studio's popularity to reach levels comparable to that of Creator/KeyVisualArts, [[Franchise/{{Nasuverse}} TYPE-MOON]] and [[Franchise/WhenTheyCry 07th Expansion]].

One of Nitro's most prolific creators is Creator/GenUrobuchi, who has gone on to write ''LightNovel/FateZero'', ''Anime/PuellaMagiMadokaMagica'', and ''Anime/PsychoPass'' independent of the company. Vocalist Music/KanakoItou is another frequent collaborator, having performed the musical themes for many of their [=VNs=] and anime adaptations. On a sad (and perhaps ironic) note, their music producer Shingo Minamino was murdered tragically and brutally in the middle of a busy street.

For some bizarre reason, the company responsible for so many dark and disturbing stories has a mascot in the pink-haired, baby-faced, be-headphoned {{Moe}} character [[Anime/SuperSonico Super Sonico]].

!!Tropes pertaining to them, and their works in general:

* AnimalMotifs: Cats and Dogs, in the Chiral titles.
* AllLowercaseLetters : The company name is stylized as 'nitro+'. Averted in their early days, where the logo had uppercase 'N' and is referred as 'Nitro Plus' (two words), instead of 'Nitroplus' (one word).
** ''[[VisualNovel/SweetPool sweet pool]]''
** Averted for ''Nitro+[=CHiRAL=]''
* AprilFoolsDay : They usually celebrate this every year. Highlights includes them quitting the whole industry altogether to become farmers in 2008.
* AwesomeMcCoolName : Some of their staff uses these kind of names as their pseudonym. Highlights includes Digitarou (their CEO), [=NamanikuATK=] ([[Main/NoPronunciationGuide spelled 'At-ta-kai' by the way]], not '[[Main/IThoughtItMeant Attack]]'), and the above-mentioned Gun Snark. One of their staff also has 'UNKNOWN GAMES' written as part of his pseudonym.
* CashCowFranchise : Currently, ''Anime/SuperSonico'', ''VisualNovel/DramaticalMurder'', and ''VideoGame/ToukenRanbu'' is this trope, with loads and loads of [[Main/MerchandiseDriven merchandises]] made for them.
* ConspicuousCG : Most of the Background/Object images in their games are CG, made by CG Studio Polygon Bangcho. The [[AllThereInTheManual artbooks]] usually shows the wireframes/rough models of said backgrounds.
* {{Cyberpunk}} : To date, they have made many works in this genre. Highlights includes "Hello, World", ''VisualNovel/KikokugaiTheCyberSlayer'', ''VisualNovel/ChaosHead'', ''VisualNovel/SteinsGate'', ''Anime/PsychoPass'', and ''VisualNovel/DramaticalMurder''. Their newest title ''Tokyo Necro'' continues this tradition, which is basically ''Film/BladeRunner'' '''[[RecycledInSpace WITH]] [[Main/ZombieApocalypse ZOMBIES]]'''!
* '''{{Deconstruction}}'''
* DevelopmentHell : Most of the official english localizations of their games. Luckily BadExportForYou is averted[[note]] The original Japanese versions of Hanachirasu and [=SoniComi=] has compatibility problems on Windows 8, with no workaround for the latter. The official localization of Hanachirasu fixed it, and hopefully [=SoniComi=] will have it fixed as well. This has been the reason on why the localizations took a long time.[[/note]]
** [[https://vndb.org/v3060 Dogra Q]]. Announced in 2008, but has no updates since 2010.
* GoroawaseNumber: ''2106'', which is spelled 'Nitro', appeared in ''[=SoniAni=]'' and ''VisualNovel/DramaticalMurder'' (as 2106 CR-L, with CR-L as 'Chiral').
* MagicalGirl : ''Sumaga'' and ''Anime/PuellaMagiMadokaMagica'' has main heroines that are these.
* MascotFighter : ''Nitro+Royale'' and ''Nitroplus Blasterz'' are these
** One of their April Fools jokes is a {{Crossover}} fighting game with [[Franchise/{{Nasuverse}} TYPE-MOON]], aptly-named ''[[ExactlyWhatItSaysOnTheTin TYPE-MOON vs. Nitroplus]]''
* MeaningfulName : The current engine used for their games is called [=N2System=]. N2 is the chemical symbol of Nitrogen.
** Super Sonico is written as 'すーぱーそに子', which could meant 'Super Sound Girl' or 'Supersonic' (as in supersonic sound). [[Main/SpearCounterpart Naitou-kun]], on the other hand, is derived from 'Night', although could be a derivation of 'Nitro' ('Nai' is spelled as 'Ni' in english pronunciation).
* NoExportForYou : [[Main/AvertedTrope Averted]], They are really open to the western market (their CEO even visited Anime Conventions in the west for market research), ''Zoku Satsuriku no [[SpaghettiWestern Django]]'' was even developed with the western market in mind, not to mention that their CEO once expressed an intent to adapt ''VisualNovel/SayaNoUta'' into, of all things, a [[TheMovie Hollywood Movie]]. However, most official localizations of their titles are plagued with DevelopmentHell that sometimes are in the same level as ''Creator/{{Valve}}''
** The Chiral titles haven't been considered for official localizations to this day, but they let their fans [[FanTranslation translate them]]. To this day all their main titles (sans ''Slow Damage'') have been translated.
** They also opened an [[http://nitroplus-global.ecq.sc international version]] for their own online store.
* ProductionPosse : Creator/HikaruMidorikawa has lent his voice [[VisualNovel/TogainuNoChi to]] [[VisualNovel/{{Demonbane}} some]] [[VisualNovel/SayaNoUta of]] [[VisualNovel/SweetPool their]] [[VideoGame/ToukenRanbu works]].
* LighterAndSofter : ''Sumaga'', ''VisualNovel/DramaticalMurder'', and ''Totono'' has visual designs and atmosphere that are this trope, but [[CerebusSyndrome still]].....
** ''[[Main/RhythmGame Soni]][[Main/RomanceGame Comi]]'' is a straight example of this trope
* OneOfUs : [[http://www.dannychoo.com/en/post/25769/Nitroplus+Office+Tour.html This blog post]] may give you an idea of this trope in full effect.
** Their official twitter is following a comic book superhero cosplayer. Additionally on the above blog post, you can find a ''Loki'' and ''ComicBook/{{Thanos}}'' figure in one of the images.
** They also collect replicas of guns.
** Some of their Artists sometimes does fanart
** Apparently some of their staff are currently playing ''VideoGame/{{Battlefield4}}''.
* [[Main/SeriesMascot Company Mascot]] : Anime/SuperSonico, for Nitro+ and [[Main/SpearCounterpart Naitou-kun]], for Nitro+[=CHiRAL=], altough they aren't exactly 'company mascots'[[note]] they are actually the official mascots for the live concerts, ''Nitro Super Sonic'' and ''THE CHIRAL NIGHT'', respectively[[/note]]
** Super Pochaco, Super Taruco and Ouka also qualifies as this, altough they are less popular.
* SomethingCompletelyDifferent : ''[=SoniComi=]'' which is 100% LighterAndSofter than their other titles. Its also their first completely-3D title, before ''VisualNovel/RoboticsNotes''
* TrollingCreator: Many of their staff members have a tendency to be really trollish just for laughs, Creator/GenUrobuchi being the poster boy example of this.
* VanityPlate : They used one in ''VisualNovel/SayaNoUta'' (CG Sequence of a weapon-like thing opening to reveal their logo) and ''VisualNovel/LamentoBeyondTheVoid'' (a shot of characters' tail followed by N+C logo)
