[[caption-width-right:200:Warning: [[CovertPervert Perverted]] SexBot]]

Yuria is a [[RobotGirl Model 100 Dutch Wife]] (hence the title; ''100-shiki'' means "type 100") -- essentially, a SexBot. She escapes her inventor's lab (naked, of course). Shunsuke-san finds her on the street ([[NakedFirstImpression still naked]]) and offers to let her stay with him for a while. She's programmed for sex, while Shunsuke is [[ChasteHero blindly]] [[CelibateHero dedicated]] to his [[IceQueen ice-cold]] [[RichBitch fiance]]. HilarityEnsues.

Yuria, being a Dutch Wife, is programmed to have sex at any opportunity. Once she does have sex (specifically, [[IKEAErotica if Tab A is inserted into Slot B]]), she will be permanently and forever imprinted as a sex slave to the person with whom she has had sex. Problem is, she is a little more self-aware than her creator intended and is able to realize the consequences if she is imprinted, and starts to think maybe she doesn't really want that to happen. She questions her programming and eventually starts wondering if what she feels for Shunsuke is truly love, [[WhatMeasureIsANonHuman or if she is really just a preprogrammed robot]] after all.

Each issue is more or less a {{filler}} episode (a ''sexy'' filler episode) where HilarityEnsues but sometimes [[MoodWhiplash veers back]] towards Yuria's confusion about life and love. Even though she reaches her conclusion that she doesn't want to be a Dutch Wife within the first few pages ("'''Dutch Wife!?''' [[LampshadeHanging You mean I won't be protecting the Earth or anything?]]") her emotional self-awareness as a person continues to grow, even though she [[DeusSexMachina inevitably winds up rationalizing]] trying to have sex with Shunsuke.

Oh yeah, it's very {{ecchi}}, just in case you haven't already figured that out, almost to the point of {{hentai}}. Except that it isn't actually pornographic, what with all the not actually having sex happening on account of nobody wanting to sleep with the people who want to sleep with them.

----
!!This manga provides examples of the following:

* AccidentalMisnaming: Lucy mispronounce Kunihiko's name as ''Cuninhiko'', a play on "cunnilingus."
* BarbieDollAnatomy: Partially averted.
* BeachEpisode: Chapter 13.
* BecomeARealBoy / IJustWantToBeNormal: Yuria spends a lot of time and effort wondering if there is any way she can be like a normal girl.
** As an inversion, Julia spends time trying to talk Yuria around to seeing the advantages of being a robot.
* BlackComedyRape and DoubleStandardRapeFemaleOnMale: It never quite gets to "rape," but what Yuria gets up to is more than just "seduction" - [[DontExplainTheJoke i.e. sexual assault and]] ''[[AvertedTrope attempted]]'' rape.
** Shunsuke is pretty damn lucky he's a skilled wrestler... SUPLEX!!!
* BlandNameProduct: The "Intendo Bee"
* BluffingTheMurderer: Parodied when a bunch of little boys find a photo of a vagina, and manage to bluff Yurin's owner into staring at her crotch and revealing the location of this mysterious hole.
* ButtMonkey: Akiba. His creations keep walking out on him as soon as he can [[IncrediblyLamePun turn them on.]] He consistently fails to ever be able to do anything about it. He repeatedly shows up on TV reports for having been arrested, running around naked, chasing his creations. Because all his later models run away, he's constantly having to resort to carrying around his "Yuria Model 28" -- a blow-up doll. (Which ''still'' frequently manages to reject him via some sort of malfunction or missing feature.)
* CatchPhrase: Lucy says "No Problem!" in English once or twice per chapter.
* CannotSpitItOut: Yuria. Justified, since she's aware that she is a robot, she ''really doesn't'' know if she's in love with Shunsuke or if it's just her programming. For the same reason, she never quite gets around to telling him that she's a sex robot, and when she does manage to blurt it out, he thinks it's some kind of strange joke on her part.
** When Julia and Yurin decide to "help" Yuria confess, things don't exactly go as planned.
* CantHaveSexEver: Yuria, if the alternative is to become a completely subservient sex slave (which is her intention). With all the sex play that ends up happening ''anyway'', this is a pretty lax restriction. According to chapter 22, [[spoiler:the exact requirement is three seconds of insertion]].
** Shunsuke, because he's faithfully devoted to his emotionally distant, entirely chaste girlfriend.
** Julia, because her "owner" is underage. [[spoiler:Subverted in that, Julia promises to keep herself chaste for him till he completes 18 years old, going as far as foreplay in between.]]
** Yurin, because the person she picks to be her "owner" is not a {{Lolicon}} and totally {{Squick}}ed out by her advances.
* CaughtWithYourPantsDown: Yuria causes quite a few of these.
* CovertPervert: Just look at her. Doesn't she look so huggable? Yeah, that's not what ''she's'' thinking.
** Although sometimes Shunsuke does allow himself to enjoy Yuria's attentions...
* CuteClumsyGirl: Yuria was programmed to be clumsy so as to be endearing.
* DeusSexMachina: As much as she tries, she inevitably reaches the same conclusion to escape whatever awkward situation she and Shunsuke find themselves in, and it involves having sex.
** Said situations include being ''stranded on a mountain'', or ''stuck on a desert island''.
* DirtyOldMan: Shunsuke's boss. This would've been a very short and repetitive series if he'd gotten his hands on Yuria and her 'sisters.'
* DoAndroidsDream: Surprisingly tragic at times. Yuria [[WhatIsThisThingYouCallLove doesn't even know what love means]], but she desperately wishes she did.
* DoesThisRemindYouOfAnything: see the entry for FootnoteFever.
* DoubleEntendre: also see the entry for FootnoteFever.
* {{Eagleland}}: The Lucy MKII play doll is very much a type 2.
** Though she was programed as an over the top version of this as her selling point.
* {{Ecchi}}: Very, ''very'' much so.
* {{Eroge}}: Volume 5 {{omake}} features the ''Yuria 100 Shiki'' {{eroge}} game as a parody of [[{{eroge}} h-games]].
* {{Expy}}: Shunsuke's boss has almost the exact same character design and personality of Kohta's Boss from MyBalls, the mangaka's next work.
* FanService: Yuria makes any excuse to get naked, wherever. Considering the premise, it's not surprising.
** Shunsuke is in great shape and good looking and gets plenty of {{Shirtless Scene}}s himself, completely outside of Yuria's actions. Not to mention wrestling briefs.
* FestivalEpisode
* FishOutOfWater: Her programming as a [[SexBot 'Dutch Wife']] means she is not exactly prepared for "normal" every day activities; see the FootnoteFever entry again.
* FootnoteFever: Frequent appearances by Little Yellow Boxes that relate one of Yuria's selling features as a [[SexBot Dutch Wife]] to her unusual behaviour whenever she [[DoesThisRemindYouOfAnything misunderstands or misinterprets a situation.]]
** For example, when Yuria becomes fascinated with the shampoo she's squirted out all over her hands, the Little Yellow Box explains that the Model 100 Dutch Wife is programmed to be mesmerized by milky white fluids.
** Since the Little Yellow Boxes address the reader as if they were advertisements for the Model 100, they do a good job of PaintingTheMedium
** In chapter 27, the boxes turn the tables and focus on Maria, explaining things such as that due to her high class upbringing she does not quite comprehend what a love hotel is.
* GirlishPigtails: Yuria.
* GoneHorriblyRight: It seemed like all of Dr. Akiba's problems with the latest Yuria models was that they had personality, enough to reject him even though they are programed to disregard at least their partner's looks and behavior, so his last creation was [[spoiler:Yuria 1000, the most advanced Yuria model, completely devoid of personality and any remarkable trait; in theory it wouldn't reject even him, or so he though... like all Yuria models she still is a Dutch Wife progamed to please men, with her lack of direction Yuria 1000 simply reached the conclusion that she should go randomly around pleasing as many men as she could find, not settling for just one master by giving them quick pleasure and not letting anyone penetrate her. In the end she was just another Yuria that Dr. Akiba couldn't keep in his grasp]].
* GratuitousEnglish: Lucy and her stock porno lines.
* HadakaApron: During Yuria's {{ImagineSpot}}s and dreams.
* [[HaremGenre Harem]]: Yuria gets two "sisters" during the series; a {{Tsundere}} and a Loli. At first they both try to also seduce Shunsuke. After Yuria defends her "ownership" of Shunsuke, they each find their own "owner." Lucy and Louie also encounter Shunsuke right away and both decide to make him their first "conquest.". (Although in Louie's case, it seems more like an actual crush and less based on programming.)
* HealingHands: If Shunsuke isn't feeling well, Yuria seems to ''think'' that her [[DoubleEntendre techniques]] will make Shunsuke [[DoubleEntendre feel better.]] Just [[DoubleEntendre not the way she intended]].
** ([[DepartmentOfRedundancyDepartment also,]] DoubleEntendre)
* {{Hermaphrodite}}: Louie was built from the top half of a female bot and the bottom half of a male one. She identifies as female, but she's frequently undermined by a RagingStiffie (which is [[BiggusDickus as thick as a human's arm]] and capable of punching through steel.)
* ICanExplain: Tried frequently. Fails almost as frequently.
** Letting Yuria try to explain is ''not'' a good idea.
* IceQueen: Shunsuke's girlfriend.
* ImagineSpot: Yuria often dreams and daydreams about her and Shunsuke being a real couple. Usually devolves into {{ecchi}} pretty quickly.
** Shunsuke will frequently hear her mumbling in her sleep and imagine she must be having pleasant dreams when she will suddenly blurt out something extremely {{ecchi}}.
* IncrediblyLamePun: One chapter includes a scene with Shunsuke and Yuria listening to a radio call-in show where the subject is "What is love." One caller seems to be relating a serious metaphor involving the letters of the alphabet. Until he gets to [[{{ecchi}} H]]. It's a more obvious pun in Japanese than it is in English.
* InsaneTrollLogic: How Yuria justifies her DeusSexMachina.
** {{Lampshaded}} by Shunsuke often. "That doesn't even make sense!"
* JailBaitWait: [[InvertedTrope Inverted]] between Julia and her underage owner.
* LampshadeHanging: Between the yellow boxes and the crack plots, this manga is way, way too genre-savvy. It works.
* LethalChef: She can't tell if her cooking tastes bad because The Model 100 Dutch Wife is designed to not mind a wide range of tastes (More FootnoteFever).
* LivingToy: Julia's "owner" is underage, so he is only allowed to "play" with her, and when his mother is around, she pretends to be an inanimate love doll.
** Of course his mother often walks in at just the right (or wrong) moment for "ICanExplain, it's NotWhatItLooksLike!" HilarityEnsues.
* {{Lolicon}}: Averted in that the guy Yurin picks to be her owner is emphatically ''not'' one and is incredibly freaked out by her advances.
* LoserProtagonist: Doctor Akiba has made an entire career out of building a robot that will have sex with him, and so far, none of them will. (Well, except the blowup doll.)
* LoveableSexManiac: ... You can figure it out.
* MarshmallowHell
* ModestyTowel: They usually don't last long.
** Or cover all that much.
* NakedPeopleAreFunny
* NoseBleed: Regularly from Shunsuke and Yuria. ''Especially'' Yuria.
* [[spoiler:NoRomanticResolution: Yuria and Yurin have not penetrated by the end of series. The series ends on a clear note in that the connection to their supposed owners are stronger than making them loyal robots through sex; in other words, love and commitment wins over uncompromised sex]].
* NoSocialSkills:
** Yuria has been programmed for one purpose. Anything outside her area of expertise leaves her pretty lost as to how to proceed, usually winding up in DeusSexMachina territory. The serious part of the plot is her trying to learn how to fit in.
** Julia and Yurin, despite also being {{Sex Bot}}s, somehow seem to have a much more practical grasp of everyday life. The fact that they are later, improved models probably has something to do with it. (Julia even has a tendency to call Yuria "the old model" much to Yuria's annoyance.)
* NotWhatItLooksLike: Inverted. Most of the time it is, with Shunsuke trying to come up with a plausible excuse why it isn't.
* ObliviousToLove: Shunsuke is [[IdiotBall mind-bogglingly oblivious]] to how hard she tries to take care of him, much less her constant attempts to have sex with him.
** After only about 55 chapters, and countless [[BlackComedyRape "seduction attempts"]], Shunsuke might be finally getting some kind of vague clue, sort of, possibly.
* OnlySixFaces: Maria and Yuria have almost the same design, the biggest differences being their hair styles. Because of this, in chapter 21 Yuria was able to pretend to be Maria in a girlfriend contest. There are also many similarities in the designs for most of the recurring male characters.
* PleasePutSomeClothesOn: Shunsuke to Yuria, very frequently.
* PrettyFreeloaders
* RedStringOfFate: Yuria believes it goes from her finger to Shunsuke's ... not finger.
** [[WhatDoYouMeanItsNotSymbolic Not to mention the type of 'string' that ties them...]]
* RidiculouslyHumanRobots: They look human, they have human-equivalent bodily fluids (which are digestible to humans!), and they can apparently heal from small injuries. On the other hand, their mental capacities are unusually limited for the trope--Yuria can't even count to a hundred.
* TheRival: In chapter 41, a former colleague of Dr. Akiba's activates "Lucy Mk. II". He then sends her to Japan so she can '''"[[EagleLand give them a taste of the superiority of American hardcore porno!]]"'''
* RunningGag: Yoshio getting found in awkward situations by his mom. And sometimes Julia.
* SchoolFestival: [[PleasePutSomeClothesOn Lots]] [[NakedPeopleAreFunny and]] [[DeusSexMachina lots]] [[NotWhatItLooksLike of]] HilarityEnsues.
* SexBot: All of the named female characters so far except Maria and Louie's roommate Kaoru.
* ShapeShifting: In the final volume, [[spoiler:Dr. Akiba brings us Yuria 1000 an emotionless dutch wife built with nanotechnology and coated with silicone, capable of taking the form of any female or any of her "sisters" by touching them, turned out to be a failure as she did not have any personality.]]
* ShoutOut: When Yuria is convinced she must have a "cheat code" to unlock some kind of special abilities, she imagines the [[ClassicCheatCode classic]] KonamiCode and a {{Gradius}} starfighter.
** Yuria Type 28 could be a reference to ''Tetsujin 28 go'' AKA "Super Robot 28" or {{Gigantor}}.
** When Julia uses Yoshio's dick as a joystick, she's performing moves from various beat'em-ups, including ''StreetFighter''.
** "Boss". Yes, the same "Boss" from MyBalls, the writers subsequent work.
** And then there's the title itself, which references the Hyaku (100) Shiki mobile suit from ZetaGundam.
** In Chapter 51, Kaneda's mental picture of a [[IdolSinger "Super Idol"]] is Haruka Amami from VideoGame/TheIdolmaster.
** Late in the series, as Yoshio turns 18, his friends remind him he can rent all the porn he wants. Yoshio's response: "[[Manga/TheWorldGodOnlyKnows I have no interest in 3D girls]]".
* ShowerScene: With excessive shampoo everywhere, of course.
* ShowingOffTheNewBody: in chapter 83, [[spoiler:Yurin eventually learns how to make her body change to that of a grown-up woman, even without her supposed "owner" ever making advances on her and modelling the body after his preferences, with the new form she adopted the alias of Lorin trying to fool Ippei into having sex with her, still she failed as the form can't last long enough]].
* SlidingScaleOfRobotIntelligence: Yuria is convinced that her robot brain must be more than capable of helping a high school student with his tutoring. Turns out, not so much; Akiba must have put "advanced math skills" low on the list of requirements for a SexBot.
* SuperPoweredRobotMeterMaids: Both the Yuria and Lucy series could potentially cause serious damage if they used their full strength. Lucy 3.5 sports a foot long penis that can break through a ''door''.
* SweatDrop
* ThereAreNoTherapists: Any sane person would assume that Yuria suffers from some severe form of sexual disorder. Needless to say, this never comes up.
* ThisIsWrongOnSoManyLevels
* ThoseTwoGuys: Shunsuke's friends who frequently come upon Shunsuke and Yuria [[CaughtWithYourPantsDown during awkward moments.]]
* {{Tsundere}}: Julia.
** Maria. She was most likely raised purely and just has a misunderstanding and worry for Shunsuke. She just stabs people with a inch and a half long point extending from her parasol. Otherwise she's so calm it's heartwarming and obvious to see why Shunsuke loves her.
* UnusualEuphemism: At one point Yuria says that semen in her mouth are "Tragic Summer Memories". Although no one was supposed to know what it meant.
* WhatMeasureIsANonhuman: Among other things, whenever someone casually refers to one of the sexbots with a word like "person", the first line of her manual (e.g. "Yuria Type 100 is a dutch wife") appears in an inset panel. Especially common with Julia, whose owner, the doll collector Yoshio, thinks she's his first real human girlfriend.
* WhenAllYouHaveIsAHammer: Yuria's programming leads her to think everything can be solved by sex. Bleeding wound? Stimulate the penis to draw blood down to it. Lost in the woods? See if you can get Shunsuke's erection to point north.
** Even in situations where it seems like she would be useful. For example, rubbing two sticks together to start a fire would be greatly helped with her impressive rate of 16 strokes-per-second (normally meant for... getting other things hot...). No, she just plows on as normal, completely unaware that success would mean ''setting Shunsuke's genitals on fire''.
* WifeHusbandry: Model 108's (Yurin) primary selling point is that the owner can mold her body and personality to whatever he wants.
** Since this is her program, ''she'' is actively trying to get her "owner" to implement the plan ''on her'' against his strong protests, so it's actually inverted.
** It also seems that, since Ippei wants to be a schoolteacher, what he "wants" Yurin to be is a typical young schoolgirl. And lately Yurin seems to be acting more girlish and less utterly perverted. (Still perverted, but not as much. Mostly.) So now it may be headed to subversion territory.
* WouldHitAGirl: Shunsuke quite regularly has to wrestle Yuria into submission, and his skills are the only reason she hasn't (successfully) raped him yet. Moreover, her inability to appreciate the finer points of social situations or basic safety has put them in ''a lot'' of awkward and/or dangerous situations [[ViolenceIsTheOnlyOption that he has literally no other way of resolving]] ([[FailureIsTheOnlyOption though he invariably tries to talk her out of it first]]).
** [[IncrediblyLamePun In Shunsuke's defense]], Yuria [[MadeOfIron has never shown any ill effects from this treatment]].
---> ''The Model 100 is built extra tough to handle many kinds of "rough" play!''
** Eventually, Yuria ends up taking a liking for that kind of rough play. (Cue the footnote detailing her masochistic programming.)
** AND eventually, Shunsuke ends up taking a liking for smashing Yuria around. He really wants to try new wrestling techniques and since Yuria is a tough girl...
* WrestlerInAllOfUs: Hilariously, Shunsuke is not only a ''puroresu'' fan, he's actually an extremely competent wrestler himself. Which is quite often all that stands between him and a sex-crazed Yuria.
** His Luchador name is "El Limpio" (The Clean) which probably must refer to his "by the book" wrestling style and to his (somewhat) clean thoughts.
*** These tropers always thought it was also a convenient DoubleEntendre IncrediblyLamePun: El ''Limp''-io. It could be coincidence, but [[ThereAreNoCoincidences given the context...]]
* {{Xenofiction}}: Yuria does not think like a human, no matter how much she wants to (which is pretty unusual for a series that asks DoAndroidsDream)
* YaoiFanGirl: Louie's roommate Kaoru misunderstands the situation, and promises to help Louie make Shunsuke "his" first [[{{Uke}} receiver]]. (For that matter, Louie herself refers to Kaoru's collection of BL as "a mountain of treasure").
