Taketo Akutagawa has been admitted to Inspiration Academy, a school where geniuses from all over Japan come to learn. What is Taketo's talent? Writing porn novels. While this earned him scorn back in middle school, here, he can let his talents shine. Everything begins when, working for the school newspaper, he goes out to meet the school's genius clarinet player, Fukune Narukara. A love story is about to begin.

Originally a LightNovel, ''R-15'' was adapted into an anime in the Summer2011Anime season.

----
!!Tropes in ''R-15'' include:

* AlienLunch: Unfortunately for Taketo, Kurabu isn't the genius [[SupremeChef chef]].
* AlliterativeName: Kurumi Kuroki better known as the chief, Beni Botan and, Kurabu Katsuyo
* AllMenArePerverts[=/=]AllWomenAreLustful: And [[GenreSavvy Taketo]] pretty much weaponized it.
* AwesomeByAnalysis: Mei
* AxCrazy: Almost literally. Ran literally conjures an ''axe'' out of nowhere as a result.
* {{Bishonen}}: Close-up, Ritsu has eyelashes too long for a boy.
* BlandNameProduct: Raika's camera is labelled "Likon" (Nikon), and there's a "Zamazon" (Amazon.com) website.
* CameraFiend: Raika, the school's genius camerawoman.
* CatGirl: Misa, complete with CuteLittleFangs and the VerbalTic of "-Nya".
* CensorSteam: Goes overboard to the point where over half the screen can be covered, at least in the broadcast version.
* ClingyJealousGirl:
** Raika invokes this trope subtly from time to time, especially regarding Fukune and Utae.
** Both Fukune and Utae feel this way when they see Taketo hanging out with the other.
* CrouchingMoronHiddenBadAss: Taketo is usually a ButtMonkey, but his words have helped out several of the girls, and in others, distracted them enough that they helped him escape from a potential beatdown, or allowed another girl to beat them up, such as during the Ran vs. Botan wrestling match.
* CurtainsMatchTheWindow: Taketo and Ran.
* CuteClumsyGirl: Kurabu
* CuteSportsClubManager: Kurabu Katsuyo the genius manager.
* DaEditor: Resident school newspaper editorial chief, [[EveryoneCallsHimBarkeep Chief]]. She doesn't resemble your average CigarChomper, but when she wants an article, ''boy'', you had better give it to her.
* DoesThisRemindYouOfAnything:
** Everything that Taketo writes is pretty much DoubleEntendre, since he's a [[{{Hentai}} H]]-novelist. This is unintentional, [[SuspiciouslySpecificDenial from his point of view]], and nobody can take him seriously. However, when some of the characters decide to read what he actually writes, the "suggestions" fly over them.
** Mai's exorcist "dance".
* EveryoneCallsHimBarkeep: The newspaper chief: Kurumi, is known only as Chief.
* FanService: Largely averted in the broadcast version due to the copious amounts of CensorSteam. But you could always do like Taketo and use your imagination. Or get the DVD.
* FestivalEpisode[=/=]HotSpringsEpisode: Episode 10
* FreezeFrameBonus: When Taketo was hit with the rock in his dream, there is an image of a girl with slightly visible [[PantyShot panties]].
* FortuneTeller[=/=]WaifProphet: Misa
* {{Gainaxing}}:
** The Chief and Utae.
** Happens a lot in the Ran vs Botan fight
** And in episode 7
--->'''Taketo''': "Boing, Boing, Boing"
* GenkiGirl: Kurabu
* GirlishPigtails: The Chief, Misa and, Katsuyo.
* GoofyPrintUnderwear: [[spoiler:Raika]] has bear print, Misa has the NumberOfTheBeast on her's and Ran's has the words [[LesYay Only Girls]].
* GunPorn: The Chief's room has many guns on her wall.
* HairDecorations
* {{Hammerspace}}: Just how does Chief keep a long rope in her mouth... [[VictoriasSecretCompartment ...or a brochure in between her melons]]?
** Ran's ''axe''.
* HaremSeeker: Ran of freshmen girls, and Botan of "art" (read: nude girls she's gotten to let her BodyPaint them). Not surprisingly, the two butt heads immediately.
* HeadbuttThermometer: Utae gives the blushing Taketo one.
* HollywoodHacking: Averted. Even though Ran can hack way faster than what it's possible in real life, she actually uses the command line to hack[=/=]crack like real hackers[=/=]crackers do
* HotScoop: [[DaEditor The Chief]] and [[CameraFiend Raika]] have the looks and the article-hungry attitude to qualify.
* HotSpringsEpisode: Episode 10.
* HowWeGotHere: Episode 3.
* HumanAliens: The chief is thought to be one.
* HypocriticalHumor:
** Ran Musen sighed at Taketo's unhealthy daydreaming in class while loading unhealthy photos on her notebook.
** And again in episode 5 she wonders "Why Fukune attracts weirdoes?"
** Whenever Ran critisizes Taketo for perverted behaviour can be considered this. A lesbian who insists that her harem call her Onee-sama simply cannot take the moral highground against a porn writer. At one point she gets in-directly called on it too, when Misa comments that she can sense a far darker aura around Ran (and Botan) when she was seducing a girl then she could from the perveted spirt, a disguised Taketo.
* IdiotHair: Tsukuru and Kurabu
* IdolSinger: Utae Sonokoe
* ImagineSpot:
** Taketo goes through one of these out of the [[LesYay implication]] that Ran Musen and Aki Yosano might be SchoolgirlLesbians, judging by their intimacy.
** Hell, his fantasies are frequent and rabid.
** And he with his words he send Utae, Raika, Botan, Mai and Santa Maria.
* IndirectKiss:
** Taketo notices that Utae is feeding him with her chopsticks.
** Taketo licking Fukune's ''damp'' clarinet reed.
* KissOfDeath: How Ran finished of Botan.
* LensFlareCensor: Taken to absurd levels. The lens flares are beyond mere flares, and involve large swaths of white covering up most of the screen. For large parts of the episode.
* LockedInARoom:
** Invoked. Taketo gets locked in the room with Katsuyo so she manage him out of his [[WritersBlock slump]].
** Played straight when he gets locked in the freezer building with Utae. They were in serious trouble if not for the Chief rescuing them.
* LoveableSexManiac: Taketo of course.
* LoveTriangle: Fukune->Taketo<-Utae
* LyricalDissonance: The song Class 1-3 uses in the choral competition is a song with a dignified melody and very dirty lyrics.
* MadArtist: Botan, with BodyPaint being her favorite form of art; she's rather infamous for it. In episode 5 we hear about the "Painted On Uniform Incident" (which involved some poor girl going to school in, well, guess), and she makes herself first known (to cast and viewer alike) by painting one of Ran's harem... leaving her ... [[CharmPerson dazed.]] Much to Ran's ire.
* MadScientist: Tsukuru Kagaku, introduced by firing a heat-seeking missile that chases Taketo across the school grounds.
* MagicalGirl: Fukune inspires Taketo to write her as one with a magical clarinet. This quickly turns into porn.
* MeaningfulName: Sonokoe Utae; it's written as 園声 謡江, but sounds the same as 其の声 歌え; when written this way, the surname and given name (respectively) mean "that voice" and "sing".
* MillsAndBoonProse: Just about everything Taketo writes.
* MsFanservice: Utae.
* MostWritersAreWriters: Taketo is a writer of erotic novels, in a light novel that isn't exactly light on fanservice itself.
* {{Narrator}}: Kiya Star, introduced as the school's genius narrator. Yes, she's diegetically narrating.
* MundaneMadeAwesome:
** The principal and his giant paintbrush.
** Ritsu's SurvivalMantra of [[MouthfulOfPi Pi]].
** Ran vs Botan.
** How Taketo uses his abilities to defeat Botan, Mai, and Maria.
** The Girls dorm transforming into a fortress.
* NiceGirl: Utae. She's the only girl who ever tries to defend Taketo from the ire brought about by his reputation. [[DoggedNiceGirl Poor Utae.]]
* {{Nosebleed}}:
** Taketo every now and then.
** And it manages to short circuit Tsukuru's crazy magnet.
* NumberOfTheBeast: Misa has them on her [[GoofyPrintUnderwear panties.]]
* ObliviousToLove: Taketo
* {{Odango}}: Utae
* OneeSama: Ran has her freshmen girls harem addresses her as this.
* PantyShot: By no means an uncommon occurrence, but episode four is focused around almost nothing but. [[spoiler:It's all a setup by Raika and Tsukuru.]]
* PetTheDog: Raika helps Taketo escape from the Girls Dorm.
* PhraseCatcher: After [[HoYay Ritsu]] [[TwistingTheWords twist Taketo words]].
-->'''Taketo''': "Ritsu the formula."
* PlayfulHacker[=/=]TheCracker[=/=]: Ran Musen would be, considering her avant-garde programming knowledge. For measure, she can hack her way into getting free exclusive concert tickets and tap into military-grade SpySatellites.
* PunnyName: ''Tons''. In addition to Sonokoe Utae (see MeaningfulName above) and Enshuu Ritsu (see SignificantAnagram below), there's Kagaku Tsukuru (which sounds like the Japanese words for "makes science"), Kurabu Katsuyo (sounds like "the club will win" in Japanese), Fukune's first name ("fuku"= to blow, "ne"= sound, an appropriate name for a genius clarinetist), and [[http://www.leica-camera.com/ Raika]].
* RapidFireTyping: To accompany Ran's crazy HollywoodHacking skills.
* RedEyesTakeWarning: Misa, the FortuneTeller.
* RomanticRunnerUp: [[spoiler: Female example, Utae feels this way in episode 10 once she hears how excited Taketo talks about Fukune. Made more painful for her since he then also mentions that he feels comfortable around her, and can tell her anything, meaning that she fell into his "friend" zone.]]
* {{Sexophone}}: The moment Chief walks in.
* SignificantAnagram There's also Enshuu Ritsu. Which, with a few kanji changed, is Japanese for "pi".
* ShoutOut:
** Taketo's introductory ImagineSpot for the second episode stars a stage performer who is a blatant [[{{Expy}} lookalike]] to [[Characters/MacrossFrontier Sheryl Nome]].
** In episode 7 Taketo [[MariaHolic Nosebleeds creates the new The seven mysteries]] of the girls dorm.
** In episode 9 Taketo and Utao sneaks in a [[Franchise/MetalGear cardboard box and wear Snake's suit, and Taketo's codename is Snake.]]
* ShrinkingViolet: Aki Yasano and Fukune.
* [[RapidFireFisticuffs Speedy Rain of Gentle Caresses]]: Ran
* StealthHiBye: The Chief
* StuffBlowingUp: Whenever Tsukuru is involved with something, it [[MadeOfExplodium tends to explode]].
* SuperDeformed: Particularly in the ending.
* SurvivalMantra: Whenever Ritsu is going head over heels for Taketo, ''π'' = [[MouthfulOfPi 3.1415926535897932(...)]] is the only thing that can straighten Ritsu's thoughts.
* TeenGenius: Everyone and they're labeled as such.
* TooHotForTV: Just before broadcast two networks pulled it from their schedule.
* {{Tsundere}}: Raika and Ran mostly, but most of the other girls fall into this trope if they're subjected to Taketo's naughty thoughts.
* UnluckyEverydude: Taketo.
* WhamEpisode: Episode 11, or as wham as [[SlidingScaleofSillinessVersusSeriousness this series]] gets.
* WondrousLadiesRoom:
** Raika ''invites'' Taketo in, but he brings up the point that if there are no girls in there, what's the point of it?
** And in episode 7 he infiltrates the girls' dorm/fortress.
* WorldOfBuxom:
** Chief is... well, her school uniform isn't completely closed.
** Also Utae, Ran and a few others.
* WordsCanBreakMyBones: Or Rather Taketo's words will send you to a "special place".
* WritersBlock: Taketo in episode 6.
* YouGottaHaveBlueHair: The Chief, Utae and a few others.
* YuriFan: Ran Musen. She seems to be a full on {{Schoolgirl Lesbian|s}}, given what she uses her programming skills to do. She even has the word "only girls" on her panties.
