History Manga / OtakuNoMusumeSan

* TheMessiah: Kanau. Her mere presence seems to have affected nearly everyone's lives for the better.
** Lampshaded in chapter 50, when two of Kanau's friends manage to trace back almost every event they've been through to Kanau herself.

* WhiteHairedPrettyGirl and WhiteHairedPrettyBoy: The true form of the Nagato family.

Otaku no Musume-san(AKA The Otaku's Daughter), is a {{Shounen}}, comedy manga that centers primarily around the life of Kouta and Kanau, father and daughter.

* EverythingIsWorseWithBears: Subverted as Kanau's friend Riko loves bears. Probably played straight [[http://www.mangafox.com/manga/otaku_no_musume_san/v05/c029/10.html here]].
** and don't forget [[http://www.mangafox.com/manga/otaku_no_musume_san/v05/c031/4.html this]]

** Another chapter has Nicchi transform into Kenshiro from ''FistOfTheNorthStar'' when talking to Kouta about letting Kanau stay with him.
** In the penultimate chapter, Kanau remembers watching ''PuellaMagiMadokaMagica'' with Kouta.

** They even manage to have a blatant {{Touhou}} (technically IOSYS) ShoutOut in [[http://www.mangafox.com/manga/otaku_no_musume_san/v04/c025/15.html an otherwise serious scene]]

* {{Pettanko}}: Haruka. Explicitly discussed in the PoolEpisode.

* BigBreastsBigDeal: Taeko is mostly a Type 5 though sometimes she shows signs of Type 3

Kouta was your average otaku, living alone in his apartment, surrounded by his figurines and anime body pillows; until Kanau came long. All of a sudden, Kouta has a daughter he never knew existed. Not only that, she is going to live with him, with no support from the mother who suddenly left her in his care. Now Kouta has to learn to be a father, all the while dealing with the rest of the crazy otaku of the Higansou.

Otaku no Musume-san(AKA The Otaku's Daughter), is a {{Shounen}}, comedy manga that centers primarily around the life of Kouta and Kanau, father and daughter.

!!This manga provides examples of:
* AbusiveParents: [[spoiler:The reason Taeko's mother didn't want to take care of her; she thought she would abuse Taeko]].
* AlphaBitch: Reika Misono. Her father is a politician and her mother is an actress. However, Reika isn't [[LovableAlphaBitch all that bad]] and her parents are fairly decent people, even if her mother is a bit snooty.
* AnimeHair: Averted, as most of the characters sport normal hairstyles. Played straight with a flashback arc involving Taeko's grandfather, who sports a Heihachi haircut (he says it's James Dean).
* [[spoiler:BabiesEverAfter]]: [[spoiler:In an omake at the end of the last chapter Haruka is seen with her young son just learning to walk. The kid's eyebrows give away who the father is immediately. Taeko also has a set of twin girls of her own with Sensei in the last chapter.]]
* {{Badass}}: [[spoiler: Landlady of all people was this when she turned to delinquency in her early teens. Also her grandfather and at least some of his friends would qualify as this too.]]
* BigBreastsBigDeal: Taeko is mostly a Type 5 though sometimes she shows signs of Type 3
* BigOlEyebrows: Runs in Kouta's family, starting with his mother. Even baby Saori has them.
* BishieSparkle: Nicchi, when given enough sweets
* {{Bishonen}}: Nicchi apparently is one when he has enough sweets. He even sparkles.
* BrokenBird: [[spoiler:Taeko as a child, particularly after the death of her grandfather.]]
* BrutalHonesty: Kouta's parents(especially his mother) are rather frank about what they think of his lifestyle.
** Also done by Nozomi Yukimura, [[spoiler:telling Kouta point blank that she never loved him.]]
* ButNotTooForeign: Niichi has an English mother.
* CanNotSpitItOut: Kouta, in his feelings for Taeko. At least when addressing Taeko directly.
** Also with a male classmate of Kanau, who always comes close but is either too nervous or his friends come in at the wrong time.
* ChekhovsGun: In chapter 13, Kouta gets [[spoiler:Member of Parliament Misono's business card]]. Forty-nine chapters later, he uses it to [[spoiler:help convince Takurou and Nozomi to give Kanau back to him.]]
* ChekhovsGunman: [[spoiler: Nicchi, during Kouta and Nozomi's first time in the art room. He can be spotted in the corner of the panel in [[http://www.mangafox.com/manga/otaku_no_musume_san/v01/c003/2.html Chapter 3]], but his presence is either missable or to be assumed as inconsequential. Chapter 58 changes that when we see Nozomi's recollection of the same event, where Nicchi's presence is much more pronounced.]]
* ChildrenRaiseYou
* CoolBigSis: Inverted. Mami is much cooler than Kouta, and more down-to-earth, but she is his ''younger'' sister (''imouto''), not older.
* DatePeepers: Kanau, Mami, and Kimiko spy on Kouta and Taeko's date.
* [[spoiler: DidYouJustHaveSex: A FreezeFrameBonus with Haruka wearing dark black stockings before she kisses the BrokenBird Kouta and she is showing her bare legs after. This also could explain how she gets his child in the end.]]
* DistantFinale: [[spoiler:The final chapter opens with Kanau's elementary school graduation two years later.]]
* TheDitz: Taeko's mother.
* DysfunctionJunction: While a comedy, a few characters have decidedly dysfunctional pasts.
* EnemyMine: For Kouta and Niichi, as is said [[http://www.mangafox.com/manga/otaku_no_musume_san/v05/c026/10.html here.]]
* EverythingIsWorseWithBears: Subverted as Kanau's friend Riko loves bears. Probably played straight [[http://www.mangafox.com/manga/otaku_no_musume_san/v05/c029/10.html here]].
** and don't forget [[http://www.mangafox.com/manga/otaku_no_musume_san/v05/c031/4.html this]]
* FanDisservice: Sousuke cosplaying [[UruseiYatsura Lum]] at Comiket. CANNOT UNSEE!
* FestivalEpisode: Kanau and Kouta go to a festival together, much ado is made about [[strike:kimonos]] yukatas.
* FishOutOfWater: Kanau being thrust into a group she knows nothing about and Kouta being thrust into a role he knows nothing about.
* FiveManBand:
** Kouta: TheHero, as the main character
** Nicchi: TheLancer, as his best friend, and ready to step up in take Kouta's place as '[[{{Squick}} father]]'
** Sousuke: MentorArchetype or TheChick, depending on how you look at it.
** Taeko: TeamMom, more or less literally, as she seems to do most of the cooking for the Higansou
** Haruka: TheSmartGuy, Smart and snarky, though a bit bullheaded.
* GagNose: Nicchi's nose, although it wasn't so when he was younger. It grows longer when the worst of his lolicon tendencies begin to show. [[spoiler:The second-to-last chapter reveals that the nose is fake.]]
* GenkiGirl: Kanau's best friend in school, on top of being an otaku, is constantly energetic.
* GenreSavvy: Being an {{Otaku}} and all, Kouta (and no doubt the other otakus in the apartment) knows a thing or two about the terminology and such, like how he pointed out Haruka looked like a {{Tsundere}} with her GirlishPigtails after her ImportantHaircut. Unfortunately, he's [[GenreBlindness blind]] to the fact that her Tsundere-ness is aimed towards ''him''.
* TheGloriousWarOfSisterlyRivalry
* HeadphonesEqualIsolation: Along with her MeaningfulName, Haruka often wears headphones, if for no other reason to emphasize her distant nature.
* HeroicBSOD: Kouta falls into one after learning [[spoiler:Taeko is married, and to Sousuke no less]]. Nicchi reveals Kouta fell into one for about six months after Kanau's mother up and disappeared almost ten years ago, and came out of it the otaku he is now. [[CrowningMomentOfHeartwarming Kanau pulls him out after only a few days, this time.]]
** Runs into an ''even worse'' one after the WhamEpisode (you know, the whole deal with [[spoiler:Nozomi never loving him in the first place]]). To the point where he's represented by a skeleton for the better part of an entire chapter. [[spoiler:Then Haruka [[IntimateHealing gets]] [[ForcefulKiss serious]]. It works.]]
* HeterosexualLifePartners: Nicchi and Kouta
* HorribleJudgeOfCharacter: Riko's older sister Rika believes Nicchi is a cool hunk who's interested in mature looking women.
* HotSpringsEpisode: There isn't a lot of fanservice here.
* IHaveBoobsYouMustObey: Lampshaded at the end of Chapter 49 when Taeko breaks up a fight. Taeko's intentions seem pure enough, but that doesn't stop Kanau from analyzing the situation as such.
* ImportantHaircut: Haruka cuts off her PeekABangs to emphasise to her elder sister how serious she is about following her own path.
* KissingDiscretionShot: [[spoiler: Between Kouta and Haruka, perhaps to represent how her motivations to express her feelings were "tainted," in a sense by Nozomi. The omake in the last chapter and the disappearance of her leggings after the fade to black seem to say a lot more than a kiss occurred in that scene.]]
* LameComeback: When Kouta is yelling at Mami for taking Kanau to spy on his date with Taeko, she responds "[[TemptingFate What would you do if I suddenly had to give birth]]!?", which Kouta immediately lampshades. [[spoiler:At that point, Mami goes into labor.]]
* LeaningOnTheFourthWall:
** When Sousuke begins telling Kouta (both of them are manga artists, mind) about Taeko's history.
-->'''Kouta''': A story about the landlady from 10 years ago...\\
'''Sousuke''': It's a bit long, but I want you to listen.\\
'''Kouta''': Uh, just how long is it?\\
'''Sousuke''': Hmm. If I only had about 32 pages a month... I'd say four to five months' worth.\\
'''Kouta''': I-I see. That ''is'' long...\\
'''Sousuke''': ...yeah. If it was my own work, I'd worry about getting tired of it.
** Also employed when [[spoiler:Serio remarks on the marriage between Sousuke and Taeko]]. [[TakeThat It isn't as subtle since it makes a pot shot at a particular group of his readers.]]
*** It could also be a reference to how certain {{Kannagi}} fans reacted when they learned that one of the characters had an ex-boyfriend, implying she might not be a virgin.
* {{Lolicon}}: Nicchi is an open and unrepentant lolicon. Played for laughs and {{Squick}} value. However,[[spoiler: this turns out to be a huge plot point in chapter 58. It's him being a lolicon that lead to the subsequent events of Kanau being born. Nozomi had feelings for him back in high school (and still does), and only used Kouta and Maesawa as ways just to get Nicchi to look at her.]]
* LockedOutOfTheLoop: Almost everybody at some point, but Kouta all the time. Hilariously though Niichi also seems to be in the know for everything that is going on but just can't be assed to tell anybody.
** [[spoiler: Especially the fact that Nozomi never loved Kohta at all.]]
* {{Landlady}}: Taeko. [[spoiler:In the final chapter, she and Sousuke have moved out, so Kouta is the new landlord.]]
* LoveMakesYouEvil: What Kouta felt, after his first experience. He couldn't forgive himself for taking the purity of Kanau's mother, even though she was the one that jumped him.
** [[spoiler: Turns out that Kanau's mother jumped him just so she could get Nicchi to look at her.]]
* MayDecemberRomance: [[spoiler: Taeko and Sousuke]].
* {{Meganekko}}: A few characters, but Haruka springs to mind.
* TheMessiah: Kanau. Her mere presence seems to have affected nearly everyone's lives for the better.
** Lampshaded in chapter 50, when two of Kanau's friends manage to trace back almost every event they've been through to Kanau herself.
* MissingMom: The launching point for the manga.
** [[spoiler: The mother has returned to take her kids away from their fathers in what could be considered the most Jerkass way possible.]]
* MistakenForServant: Taeko gets mistaken for a waitress in an Akihabara MaidCafe, because on the one hand all waitresses on that day were dressed up in school uniforms (and Taeko was wearing one) and, on the other hand, she [[YoungerThanTheyLook looks older than her actual age]]. A completely reverse case (mistaken for a schoolgirl) happens once to her mother who looks [[OlderThanTheyLook younger than her actual age]], and ''is actually'' a waitress in a CosplayCafe.
* MoodWhiplash: Sometimes the transitions are smooth, other times you're jerked from farce to drama.
** This is especially true during the WhamEpisode. Revealing that [[spoiler:the main character's primary love interest is not only married, but has been for ''three years'', to one of his close friends even]] and then trying to play it off as comedy is a big reason why some fans dislike it.
* {{Nosebleed}}: Haruka gets a small one [[http://www.mangareader.net/839-46726-31/otaku-no-musume-san/chapter-44.html at the end of chapter 44]], when Kouta comes out of his room in the morning in a suit and glasses.
* NotGoodWithPeople: Kimiko is a rather extreme case, [[spoiler:to the point where she abandoned her own daughter, Taeko.]] She '''does''', however, [[FreudianExcuse have an excuse for this.]]
* ObliviousToLove:
** Taeko to Kouta's crush.
** Kouta to ''Haruka's'' crush (and to Nozomi's returned interest in him ten years ago, which led ultimately to the events that kicked off the manga when she finally got sick of his obliviousness).
*** [[spoiler: Subverted: Nozomi never loved Kouta in the first place; she only used him to get her real love interest, Chihiro (Nicchi) to look at her, as she ''still'' hasn't given up on him.]]
* OlderThanTheyLook: Taeko's mother
* OnlySaneMan: Considering the residents of the apartment complex, her friends, her own father, and her mother, Kanau comes across as this, at least to herself.
* OperationJealousy: By Nozomi Yukimura. Gone horribly wrong and [[spoiler: the cause for the majority of the plot so far.]]
* ParentalAbandonment: [[spoiler:Taeko's mother, explicitly. Her father isn't present either.]]
** Kanau herself counts, since her mother just sent her off to the father she'd never met to concentrate on work. [[spoiler: She's returned, and intend(ed) to take her kids back without being found. She ultimately gets away too.]]
* ParentalFavoritism: [[spoiler:Haruka is the least favored of her siblings, at least according to her.]]
** ''Grandparental'' favoritism also plays a prominent role here, as [[spoiler:Mami doesn't want her (and Kouta's) parents to find out that Kanau (and not her own child) is their actual ''first grandchild'']].
* [[spoiler:PedophilePriest]]: [[spoiler:Nicchi becomes one by the time of the epilogue.]]
* PeekABangs: Haruka's original hairstyle, which imitated her older sister's.
* {{Pettanko}}: Haruka. Explicitly discussed in the PoolEpisode.
* PornStash: To the occasional disgust of Kanau and mortification of Kouta.
* ProudToBeAGeek: As expected of the main otaku cast, but [[spoiler: Taeko's grandfather]] really came as a surprise.
* ReplacementLoveInterest: [[spoiler: Takurou is this, of a sort, for Nozomi. His slight resemblance to Nicchi (primarily their hairstyles and the shape of their jaw) isn't made obvious until the two meet face-to-face during Kanau's birthday party.]]
* RunningGag: Several. Nicchi's loli tendencies, and his pacification when fed sweets. Kouta's total inability to be badass, even when doing something badass. Kimiko always showing up in cosplay outfits. Also, Nozomi's jobs get increasingly ridiculous.
* SceneryPorn: Plenty of detailed backgrounds.
* SecretRelationship: [[spoiler:Sousuke and Taeko. They're married to each other.]]
* SelectiveObliviousness: One of the side characters displays this towards Nicchi.
** Or everybody failing to notice the Nagato family.
* SeriousBusiness: Mami's quest to keep the "first grandchild fever" focused on Saori.
* ShipTease: Haruka and Kouta. In spades.
* ShoutOut: To plenty of anime and manga series, but the ''MaisonIkkoku''-referencing gags are the best.
** The closing statement by Kouta in chapter 58 might be shout-out to Osamu Dazai's No Longer Human.
** They even manage to have a blatant {{Touhou}} (technically IOSYS) ShoutOut in [[http://www.mangafox.com/manga/otaku_no_musume_san/v04/c025/15.html an otherwise serious scene]]
** Haruko's OldShame may be one to YamiToBoushiToHonNoTabibito.
** Chapter 61 has Kouta breaking down Kaiji-style (his nose even turns knife point sharp!)
** Another chapter has Nicchi transform into Kenshiro from ''FistOfTheNorthStar'' when talking to Kouta about letting Kanau stay with him.
** In the penultimate chapter, Kanau remembers watching ''PuellaMagiMadokaMagica'' with Kouta.
* ShowWithinAShow: Given that one of the main characters is an otaku, this does play some role in the story.
* SinkOrSwimFatherhood
* SlasherSmile: [[spoiler:Nozomi]] in the heartrending antepenultimate panel of chapter 61.
* SliceOfLife: One of the genres the manga falls under.
* SlidingScale: Kanau hilariously uses one of these to judge Kouta's actions. The scale ranges from pervert to otaku to father to papa.
* SocialServicesDoesNotExist: Averted and played straight. They exist and are referred to in the manga, but they never take an active role in the story. [[spoiler:Even when they should.]]
* TakeThat: You can't help but think that [[http://www.mangatoshokan.com/read/Otaku-no-Musume-san/Nicchi-Scans/50/3 Serio's dialogue in the second panel]] was a deliberate shot at those who were upset about the WhamEpisode.
* TitleDrop: At the second Comiket of the series, one of Kouta's friends came by with a game of this name. It was translated... somewhat differently.
* TrueCompanions: Arguably, the tenants of the Higansou apartments
* {{Tsundere}}: Haruka towards Kouta.
* TykeBomb: Nicchi's uncle likes to train the children at his orphanage in various forms of combat. Mostly [[ItAmusedMe for his amusement]].
* VillainousBreakdown: [[spoiler:Nozomi in the second-to-last chapter when she and Kouta are arguing over Kanau's custody, to the point where she completely puts down Kouta's (and indirectly her new husband's) otaku habits. Kouta's nonplussed response makes the scene all the more gratifying.]]
* VisibleSigh
* WhamEpisode:
** The [[spoiler: revelation that Sousuke and Taeko are married]] definitely qualifies for one of these. Also has elements of the ShockingSwerve, since it was completely unexpected, though subtle hints were dropped, and [[spoiler:[[ShipSinking completely tosses out the possible Kouta/Taeko relationship.]]]]
** [[spoiler:The reveal that Kanau has a younger brother.]]
** [[spoiler: The chapter that reveals that Nozomi never loved Kouta from the start, and her real love interest is Nicchi. To top it off, she's come to take Kanau and Tsukamu away from their fathers, with Nicchi helping her.]]
* WhiteHairedPrettyGirl and WhiteHairedPrettyBoy: The true form of the Nagato family.
* WifeHusbandry: Used to prevent an attempt to seize property from [[spoiler:Taeko]].
** And to make a landlady like the female lead of ''MaisonIkkoku''.
* WiseBeyondTheirYears: Kanae tries to be, needing her dad to tell her she's 9 and gets to be a little selfish sometimes.
* YaoiFangirl: Haruka and her friend Rika, who {{Squee}} when viewing Kouta and Nicchi as [[http://www.mangareader.net/839-39449-12/otaku-no-musume-san/chapter-29.html something more]].
* YoungerThanTheyLook: Taeko. Taken together with Taeko's mother being [[OlderThanTheyLook older than she looks]], it makes most people think when they're together that they're friends or siblings.
** Or, in one extreme stretch early on, that the roles were reversed and Taeko was the mother of a teenager.
** And if you want to stretch it, Kanae. She was born on Feb 29 so she is technically the age of 2.

* {{Nakama}}: Arguably, the tenants of the Higansou apartments

* MistakenForServant: Taeko gets mistaken for a waitress in an Akihabara [[{{Meido}} maid café]], because on the one hand all waitresses on that day were dressed up in school uniforms (and Taeko was wearing one) and, on the other hand, she [[YoungerThanTheyLook looks older than her actual age]]. A completely reverse case (mistaken for a schoolgirl) happens once to her mother who looks [[OlderThanTheyLook younger than her actual age]], and ''is actually'' a waitress in a cosplay café.

* {{Badass}} [[spoiler: Landlady of all people was this when she turned to delinquency in her early teens. Also her grandfather and at least some of his friends would qualify as this too.]]

* LameComeback: * TemptingFate: When Kouta is yelling at Mami for taking Kanau to spy on his date with Taeko, she responds "[[TemptingFate What would you do if I suddenly had to give birth]]!?", which Kouta immediately lampshades.

* TemptingFate: When Kouta is yelling at Mami for taking Kanau to spy on his date with Taeko, she responds "What would you do if I suddenly had to give birth!?" [[spoiler:Naturally, she promptly goes into labor.]]

* AlphaBitch: Reika Misono. Her father is a politician and her mother is an actress. However, Reika isn't [[LovableAlphaBitch all that bad]] and her parents are fairly decent people.

* AbusiveParents: [[spoiler:The reason Taeko's mother didn't want to take care of her; she thought she would abuse Taeko]]

* {{Landlady}}: Taeko.

** and to make a landlady like the female lead of maison ikkoku

* NotGoodWithPeople: Kimiko is a rather extreme case, [[spoiler:to the point where she abandoned her own daughter, Taeko.]] She '''does''', however, [[FreudianExcuse have an excuse for this.]] [[{{YMMV}} Whether or not it's passable is up to the reader.]]
