Kono Naka ni Hitori, Imouto ga Iru!

First off this show is terrifyingly under-rated. However I understand why, the fanservice is pretty over the top and in the first 3 episodes they have several momentum breaking fanservice scenes for no good reason. These scenes are so bad I might have dropped this anime had I not read a review advising to stick with it and that it got better, I hope that others will do the same as well.

Story: 8.5

First off this story seems a little shallow with the "Don't accidentally date your sister!" plot device seeming like it won't get much done. However the story decides to throw twists in pretty ... constantly, doing a good job to keep you on your toes and doubting what you know. The liberal use of fanservice aside they actually create a desirable main lead and a reason for these girls to be interested in him. For a harem they also take the interesting route of starting him off with 2 romantic interests and then expand the cast, however by the end of the anime there are only 3 real competitors so it hardly feels like a normal harem, and that's a great thing. This anime is a Mystery Harem in the order, never letting go the fact he can't figure out his sister yet keeping it interesting by throwing in new characters and motivations. The MC gets in a load of stereotypical ecchi harem situations but unlike most actually has reasons to be in them. A good example of this is when the female cast believes he is 'gay' and decide to try to straighten him out through seduction. It gives us several scenes that you would typically see in an ecchi anime but actually bothers to make up a logical and fun reason to have it, and for that I thank this anime. Also tangent here, the MC in this can actually dance, I couldn't even of another Harem where the MC could dance well, this sadly is ruined a bit by the fanservice they smash in during this time however.

Art 6.5:

The arts not bad, but the animation is rather weak, the intro is utterly guilty of this feeling like its shot at half frame rate, I checked 3 different sources to see if this was an error but its really is just bad. It feels like they might have done the intro after making the whole rest of the anime. The show itself uses a lot of still shots with pan and zooming. The characters are drawn well enough (though the breast size seems to be whatever is convenient for the scene...) to be quite likable, but when comes to backgrounds and animations they're bellow average.

Sound 8:

The sound design of the anime is quite fitting, its not impressive like some anime (Fate/NGNL) which sweeps you off your feet but I never felt the lack of it or mixed feelings like I've gotten in shows like Mahouka Koukou no Rettousei. The voice actors do solid jobs so I have no complaints, only sad there are no standout tracks that make me have to go look them up (Date-A-Live) on the spot.

Characters 9:

How can I give a 9 to such generic characters? Honestly its because they act like they're supposed to. The cast are pretty stereotypical character models for harem females for the most part but they act like it. They are over the top and do stupid things but doing so in character makes them much more likable, I wouldn't mind if they were more complex characters. However that's what gets you a 10 in my scores, so despite the fact that I really liked them I had to dock them a point for not having too much to them. I will say this is the first time I've been interested in 3 female leads in a harem. Normally only one will stand out, two at best but possibly because they don't dig too deep with them they're all fun and I don't harbor strong feelings towards the one I want to win like normal.

Overall/ Enjoyment 8:

I rate animes off my enjoyment of the world. I'm a bit different from others in that I like the world created to be intriguing enough to want me to learn more about it. This anime made me go check the wiki for info about it after I finished, that automatically gets an 8 from me as I wanted to learn more about. Sadly very little of the manga is translated and none of the light novel, however the twists keep coming from what of the wiki I read. This series really suprised me, while I wouldn't call this a masterpeice it was well worth my time and its a shame so many will give up on it after reading these reviews

Shougo Mikadono The male protagonist who is the heir to the Mikadono Group. For him to take over,needs to graduate from school as well as finding a life partner so moves to a new school to find that girl.

Simple enough premise, But what sets this series apart is there is a reoccurring sub plot, which is that Shougo father had a kid with another women, a story that if got out in the press could ruin the company's reputation, The story is Shougo trying to find who this girl is, This plot is doing REALLY Well, its presented similarly to a "Murder Mystery/Who Done It?" ... Which in enjoyed, they gave you just enough that you WANTED to watch episode after episode to find the next clue.

Up to a point in this Anime i was rather enjoying it, The Characters had a charm to them, and you get attached to the main lead as for once he wasn't as Wimpy as other guys, But nearer the end of the series, it lost it's focus on the "Finding a Life Partner" and pushed the Sister plot a little too much and as a result felt really rushed the last few episodes and left and unsatisfactory after taste, If it didn't end the way it did, Leaving parts of the story not even resolved apart from MAYBE some later OVA (Or 1 Episode OVA Which is an Unaired 13TH Episode) Which could change my ending views, But it comes a little too late for the series as a whole up to this point in time.

An Anime that started off strong and had some unique things to show, But tailed off near the end, Hurt the scores a little, still a good series, just not great.

My sister is among them! As undoubtedly noted in synopsis, this follows a young lad slated to helm his father's company. To that end, he's transferred to a prestigious school with the goal of choosing a wife. To add a plot twist, he gets a mysterious caller who names herself his sister--and in that culture, marrying your sister is a terrible scandal!

That's most of the story. Most of bits remaining consists of Shougo's getting along (or not) with the various girls. This is a harem story and ecchi genre, so panty shots and other lewd stuff happens. The aforementioned mystery begins appearing in episode 9, ... but if you've read any detective or mystery stuff, you'll probably be able to guess some of it.

Overall, the story was meh. I don't mind some suspense, but had to force myself to sit through very bland characters and their schoolgirl doings to get to the "what's really going on behind the scenes?" Just me, but the story felt stilted aside from the mystery.

Art's pretty straightforward. Each girl is reasonably pretty, and the expressions look human enough. It's possible to forget you're watching an anime, if try hard enough, but otherwise nothing remarkable.

Nothing about the sound or music impressed me. Maybe my high standards, but it felt like the anime's producers were rushing to get it done rather than get high-quality work.

Characters...eesh, seen better. Shougo is very much not a confident guy, always easily pushed around. It's only when he decides to take on the mystery that he suddenly becomes fascinating. Even after, nope, he doesn't have any confidence with girls; frequently it's the girl who asks him on a date, he just goes along with it.

Now the girls:
1) Konoe is a typical "easy catch for harem guy"
2) Myabi, your really insecure girl
3) Kunitachi, student council member who puts on a fierce air to hide her own bashfulness around Shougo. If this is an tsundere character, that never gets explored nor explained.
4) Tendou, student council president, is just a rambunctious kid with great love of food
5) Sagara was genuinely interesting for a bit, as she is involved deeply in the mystery and doesn't fall for Shougo suddenly, but after the series she's just another has-been

Enjoyment...if you come without standards, maybe you'll enjoy the suspense and fan service. I prefer anime with a good story, believable characters, and solid plot. Definitely not a good choice for serious anime fans.

Overall, it was very bland. I found the answers to the suspense probably the only exciting thing, everything else felt too rushed to be worthwhile. I actually stopped watching midway through once because this was so dull.

All i can say that is the anime should be called "Will I Bang My Sister?" because...

duh its a harem and boy he doesn't know which one is his sister among his group of horny lady that want him

Hey folks this will be my review for Kono Naka ni Hitori, Imouto ga Iru. There are plenty of words to try and accurately describe how terrible this anime is, however you may feel like I'm over exaggerating. Simply put, think of a deep exasperating sigh and the feel of dragging frustration and boredom, and you will have the feeling of watching this anime.

The story starts off poorly but at least alright enough to watch. Our male MC Mikadono, Shougo is attending his fathers funeral when through the wall a female voice comes and tells him that she is his sister. His mother arrives and ... tells him that to inherit the company he also needs to find a woman who he truly loves and marries her. This leads to the troubling mystery premise of our show. Shougo must attempt to find a wife at his school and his sister could turn out to be the one he chooses, which he is fervently against.

As the story progresses we are shown around 6 different girls, two being the most likely to be chosen. While all the girls gather around we have some of these girls pretending to be his sister for various reasons and personal gains. This is where the story becomes tedious and aggravating. We watch as shougo gets bothered and tricked and lied too, then he learns the true identity and all is forgiven, then the cycle repeats. We do eventually get to find out who his sister is however nobody is chosen to be his wife.

The art and sound were not bad. Art was a bit old. the music was pretty good and the voice acting again pretty good.

The characters were stifling. Shougo was too nice and understanding yet sometimes dominant. Most of the girls were clingy and un inspired blank molds. They didn't even bother to give them personality. Two girls out of the bunch stood out, one being a professional assassin who likes to reduce her scent by being naked in shougos room and the other a witch clothed spectacled girl who runs a maid cafe. I'm not even going to bother naming the cast because it just doesn't matter.

I hated this anime. I started watching it and it seemed like it might get a 6, however after the third sister impostor and the terrible writing and scenario scripting I nearly dropped it. I can't believe people can give decent harems low scores then look at this and say, "yeah that wasn't bad, have an 8". I love these themes and tags too, so it isn't like I dislike the anime for what it is at its core. It was just poorly written and planned out. Don't watch this, save yourself the time.

TLDR: This anime is terrible, don't wast your time. Poor writing and scenarios, no personality characters, no conclusion to the romance.

At first glance, this anime looked like a harmen anime and I was right from the first look. But surprisingly this anime tries to approach the viewers with a mystery story for the next 12 episodes while the main character looks for his sister so he doesn't accidently marry her. To make it worst, his sister has a brother complex which doesn't help at all.

So in conclusion, bad mystery (easy to guess whats going to happen), obvious harmen, and insest to wrap it up. Skip this anime unless you are here for the mediocre butts and nudes.

Overall Rating
6.2

You ever play where's waldo and get super pissed because you really can't find that sneaky bugger? Well, welcome to Kono Naka and trust me. You really won't know where waldo is until the very end.

Story: So the story is based around our main character who happens to be the lucky recipient of a huge Trust fund but alas he must first get married. That's where the story takes huge turn. You'd think to yourself, "ok, well he's gonna meet a bunch of girls and fall in love." WRONG! That's where the unique part of the story comes in to play. It just so happens ... that one of the girls is his sister.

Characters: You know the characters aren't awful. They might at times seem like they're trying way too hard but that's what makes the show so amazing. It really keeps you on your toes and wondering, "damn, which one is the sister." In fact, my guess to who was his sister was completely wrong.

Overall: So ya, this show has it's little incestuous twist but in all honesty it makes the show very funny and it sort of turns it into a little guessing game. You know after reading other reviews I noticed that most people either hated it or loved it. So if you do plan to watch this. Don't expect some amazing love story because that's not what this is. If you plan to watch this, which I do hope you take the time, understand that this is more comedy then it is romance.

This anime is one of the worse harem anime I've seen in my life. Stuff like Arifureta Shokugyou de Sekai Saikyou is at least funny to laugh at... THIS anime went from "OK this is kinda decent a little cliche but hey odd premise." to- "This anime is straight up homophobic and brain dead." within 3 episodes. Doesn't help the "trap" character (Ikusu) is one of the most useless characters next to Tendou and Mei who I questioned their existence 24/7.
here is an example from episode 3: https://twitter.com/sithgem/status/1259303671331946498?s=20

I watched this with 2 other friends and dear lord- all three of us were begging for it ... to end by episode 7.
The story is convoluted/overstuffed, forced, awful both morally and visually, and terribly paced.
I can't believe voice actors talented like Takahiro Sakurai took part in this filth.

1 out of 10.
This anime is a one time hate watch with peek enjoyment value in episodes 1 and 2.

Don't fuck your sister.

Kono Naka takes a unique approach to the problem of maintaining dramatic tension in a comedy harem anime. Most series write some kind of socially debilitating trait into either the protagonist or the girls to prevent them from resolving situations in a sane way and allowing for the escalation of increasingly improbable hijinks.

In contrast to this, in Kono Naka has comparatively sane and level characters on both sides. Instead, they build the tension through the mechanism hinted at in the story's title: one of the girls in the harem is secretly the protagonist's sister (and he knows it). Since the protagonist has to get married ... before graduation he's under immense pressure to find a girl he likes (and there are plenty interested in him). Over the course of the series, these two forces push him back and forth between playboy and gynophobe.

It's refreshing because the actions of all the characters are (more or less) relatable; there are no insane characters or total idiots -- you can imagine these events actually taking place.


It's not perfect of course. The anime is composed of three arcs. The first arc is by far the best (4 episodes). The second arc is quite weak (it could be cut without losing anything important). The third and final arc is ok; it picks up where the first arc ended but it's pretty predictable (my guess of the outcome made during episode 1 was validated in episode 12).


To summarize: It's a show with a neat premise and OK execution. It could be better in the middle and the ending is predictable, but if you like harem comedies this is one to watch.

If she looks like an imouto, sounds like an imouto and acts like an imouto, then she probably is an imouto.

Kono Naka ni Hitori, Imouto ga Iru! also known as NakaImo or My Sister Is Among Them! So it is supposed to be mystery anime in which main character, Shougo Mikadono, is looking for his future wife, but among those girls there is also his mystery sister. OMG what a twist!

This guy doesn’t think incest is wincest, so he wants to find out who is imouto and avoid choosing her accidentally (imouto for some twisted reasons wants to be chosen though… she is ... one of those incest-imoutos like Kirino Kousaka from Oreimo or Akiko Himenokoji from OniAi, if that's your thing this anime is must-see I guess).

There may be some spoilers ahead. But I think I don’t even need to tell you who is imouto to ruin the mystery, show ruins it without me.

At first this concept sounded pretty stupid to be honest, but also kinda promising comedy-wise so I decided to watch. I like harem, comedy and ecchi combination and mystery sounded refreshing addition, how that would even work?

Well… it didn’t work.
Mystery was just not very good. Honestly I guessed it right before watching any episodes, judging by the character designs alone I had a hunch who is imouto and it turned out to be right very soon with all those little but obvious hints and even more obvious red herrings… That was very disappointing, I was almost expecting to be proved wrong because that would’ve made mystery good, or actually I wanted to be proven wrong. But it was just as predictable as I feared. Predictability is of course a curse in mystery genre and this anime suffers from it a lot.

And yes I also predicted that after the mystery Imouto is revealed (the end of this anime) eventually it turns out they are not siblings after all (in light novels) - that guess was right too it seems. Sighs… Plot twists in light novels are honestly just ridiculous and confusing to be honest, but not surprising in a good way. Good mystery is surprising, but simple. This was anything but…
I only talk about anime from now on, so imouto remains imouto for me, I am not planning to read light novels and honestly seems that anime is at least better than them… It doesn’t mean much though.

Story: 3 Good ideas here and there, but mostly gone totally wrong. Everything goes as you expect or then your expectations were too high. Seeing those hints or identifying red herrings doesn’t make you feel smart but makes you wonder if you are expected to be stupid. Fortunately show seems to realize this at times and don’t dumb down the most obvious. But it still doesn’t save the mystery from being predictable which makes it boring and frustrating to watch.

Art: 6 Mediocre. Nothing special, not ugly, but pretty simple and rather generic character designs. Very light colors, which is a pretty interesting stylistic choice. There is nudity which means some bare oppai here and there. You’ll be warned.

Sound: 6 Nothing especially stands out, for better or for worse. VAs do their job, OP and ED are there but I don’t remember them anymore... that tells something.

Characters 4: There is this usual harem-cast, one guy and his girls. I personally liked Shougo, he is generic and has not much character, but he is not a complete loser. He is actually somewhat capable, not just kind. He can dance, reason and control his sexual impulses pretty well even in those lucky pervert situations he finds himself in all the time. And he is also rich, future president of his father’s company and sort of guy that girls would actually be interested in (for monetary reasons alone). Problem in many harem animes is that the main character is very useless in all ways, yet all the girls fall for him just because he is after all a nice guy. Shougo is a rich guy who is also nice. Yet he is boring as main characters usually are, there is nothing especially personal in him, and he doesn’t develop much. There is also this cliché that he has lost his memory and these ”new girls” are actually his childhood friends who have (of course) always loved him. Yes they have that cliché too. Girls are also pretty unoriginal. Tsundere, airhead, another tsundere who is elitist, cosplaying genius, reverse-trap modern day ninja and girl that is practically just boobs. Honestly that is how I would describe Konoe Tsuruma, she likes cream puffs alright, but other than that her character traits are just... her cream puffs (more ways than one). Okay she is also revealed to be homophobe, not a redeeming quality. Another homophobe is the tsundere Miyabi Kannagi. She actually says that the incest is better option than homosexuality!?.... Like what is wrong with this anime?! I understand that many in Japan are rather conservative, but I haven’t seen such a homophobic anime before that says incest is better option…. It’s just those jealous characters in that one episode but still… very weird and frustrating.
Cosplaying genius Mei Sagara and elitist-tsundere Rinka Kunitachi are a bit more promising characters, but development is minimal and all girls have pretty much same arcs, they are all suspected to be sisters for some reason, they fall in love with MC and join his harem after misunderstandings are cleared up. Airhead class president Mana Tendou joins the harem just because all others do and has no arc of her own.
Mizutani Ikusu or Mister X, and of course she is really a girl that surprises no one after you see and hear the character and Mister X is also the cause of previously mentioned unneeded burst of homophobia. She is some sort of joke character and as spy, or sort of ninja, she tries to uncover the identity of the sister along with main character, she also hangs around naked for ninja-related reasons (just fan-service) and despite her cross-dressing and obvious lack of sexual education she is probably the best option of all those girls.

Enjoyment 5: I’m easy to please, yet this mystery was so lacking. Comedy was at times poor as well and overall predictability made this anime mainly boring. It had some ok jokes though but not much, not enough to make it enjoyable. I was expecting a surprising twist.... it never came.

Overall 4: Predictable attempt of ”mystery”, ecchi was mostly just mediocre at best, characters were cute but rather shallow and had no development. There were boobs though.... so I give decent I guess. I've seen worse :D

Totally underrated.

The cover art, the synopsis as well as the overall ratings it was given on this website (which I personally do not agree with) might give hints that it'll be your standard cliche harem anime. I suspected as such at the beginning.

Don't judge a book by it's cover. I can't say that it's completely original but it's definitely above that your cliche harem anime. Interesting plot development, mystery and plot twist. Introducing new characters into the story is smooth, not just appearing out of nowhere and 'we have a new transfer student today' kind of thing.

It's not repetitive in how the MC ... approaches and deals with each character. AND most importantly, the MC is not a blockhead, he actually can use his brain for something for once.

The only drawback for me was the fact that it has quite a bit of uncensored parts, which might deter those anime fans who don't want to see that kind of stuff. You were warned!

Overall, this anime really deserves more attention.

Nakaimo attempts to deviate from the normal harem trope using the common moe cliches of little sisters and archetypes, changing from an average harem to one that ends up being somewhat opposite of just that. However, because of the more dramatic and serious tone of the show, the impact of the story falls flat in an attempt to maintain its drama with an environment of moe blob archetypes and underdeveloped characters.

There's nothing special to be seen in Nakaimo. The art and animation are sub-par at best, and most if not all of the character designs are nothing special, other than hair color and someone who ... wears a witch costume through a good portion of the series. Music did not stand out, nor make much impact on any dramatic scenes that deserved the attention. At the very least, the story itself is unique and a bit of a departure from the normal harem trope, but for reasons to be further explained in spoilers, it can't achieve its full potential of drama.

The biggest weakness of this anime is its story-telling and pacing, and the characters involved in it. A good harem would present its cast of characters, and put them through some emotional trial, and force them to go through dramatic character dynamics to help them grow and form more intense relationships with each other. Unfortunately, for Nakaimo, rather than having regular character development, it puts the viewer in the same position as the main character; unaware of his surroundings, and confused.

What makes this anime different from other harems is that instead of having to build relationships with multiple girls, our main character has to tread lightly and meticulously pick a suitor to marry, and is also wary of being lured in by his illegitimate little sister. So with this atmosphere, Shougo is constantly suspicious of the girls around him, hindering the relationships between them to grow. This is the exact opposite of what we need in a main character and his relationships with other girls.

-Minor Spoilers, but In-Depth review follows-

As if that itself wasn't enough of a problem, each girl has her own reason to actually go out of her way to fake being Shougo's little sister. This is the show's method of presenting trial for our main character, but in doing so it actually lowers the quality of the show. Being that it is a short series, each girl gets roughly 2-3 episodes to herself with her scheme of trying to pretend to be Shougo's little sister, and considering we don't actually find out who it was or why they did it until the end of their arc, there is little to no actual development of the character herself, nor any growth in the bond with Shougo.

When the final mystery of the anime is revealed to the audience and main character, the unfortunate truth is that the revealed character didn't receive the proper development over the show. Even the last few episodes that should be dedicated to this character were not, and further hindered the climax of the show. but it is fair to say that she receives the most attention and development compared to the other girls (which isn't saying much). Her and the 'side-kick' character that lives with Shougo, Mizutani Ikusu. She is probably the most interesting character as far as personality goes, for her upfront and bold appearance, while being naked for most of the show.

Nakaimo definitely has good grounds to be different, but unfortunately it's too short and too quick for it to get anywhere. It lacks the time and devotion needed to interesting characters, and hurts itself as a harem anime because of its unique plot and attempt to be bigger than it really is.

This anime has probably been one of the strangest shows I have ever watched. I am aware of unpleasant stigma surrounding "imouto shows" and yet I found NAKAIMO to be a genuinely nice show. Regarding all the tags the show is labeled with: Comedy is only from interactions with the harem, Ecchi a very appropriate tag considering the bizarre abundance of nudity and fanservice, Harem is well self-explanatory but there are only really 3 girls so rest assured, Mystery is probably the most relevant tag since there is actually a decent amount of intrigue that is built up, Romance is honestly not really developed like ... in most harem anime, School is self-explanatory around 98% of the story takes place in the same city. NAKAIMO isn't a typical imouto show, it subverts those tropes rather well but falls I admit it does indulge in very common harem tropes.

Story: 7 (Better than I expcted)
It's quite a mild story, but it does not create BS elements that change everything. It is fairly linear, following the protag's analysis of each girl and determining whether or not if they are his sister. However there are patterns you can observe and thus deduce who the culprit is. Major plot events have a decent amount of emotional and subtle foreshadowing behind them. All in all, the story will honestly surprise you as it differs greatly from conventional harem anime.

Art: 6 (A bizarre amount of nudity?)
It greatly baffled me when I saw the first slice of nudity from this show. Most of the nudity isn't even used for ecchi moments, just when the girls are in a bath/shower. The weird thing is that sometimes you would see nudity in these scenes whereas others featuring the exact same character wouldn't. They probably should've tried to stick hard to one demographic, either adult or adolescent but the story would probably be more enjoyable for an adolescent. The fan service is usually pretty short and obviously embarrasses the girls in various "cute" ways. Regarding character or background design, nothing really stands out too much. I will probably forget the names of most of the characters in a few days.

Sound: 6 (Falls into harem tropes)
The music played at any given point will usually indicated to me what was going to happen next. For instance, it was really obvious when a girl was going to walk in on the protag's accidental molestation of a different girl. The OP is pleasant and probably the best musical part of the show. Didn't really watch much of the ED.

Character: 5 (Sometimes? more depth than you think)
Of all the main characters, only protag and one of the girls (not listing cause spoiler) gets thorough development. Both individuals learn about each other and form many friendships with other students. The other students however, are typical school council or harem tropes unfortunately. Protag's mom is barely in the show and all the businessmen he talked to are pretty much one-note. You would think that harem shows are usually character driven, but this show doesn't follow that trend.

Enjoyment: 7 (Overall enjoyable)
Although stale at many points in the last few episodes, this show was able to keep me entertained through revelations in the story. Some loose ends are probably intentional left unfinished but the ending was passable. If you're watching this for the ecchi, this show probably won't do you much good. If you want to watch a harem, this show is unique enough to provide you with a different experience (I've watched quite a few harem anime up to this point). Comedic parts of the show are pretty lacking, often relying on tried and tested rom-com scenarios (shopping for clothes, falling on each other, etc.).

Overall: 6 (Good if your standards are low)
NAKAIMO is my no means a must-watch anime and I honestly wouldn't recommend watching this show if you are trying to enjoy some anime or are getting into it. If you've watched a lot of anime and know what to expect from the "harem", then this show will be a good time waster. If you want some soft-hentai material, this will probably suit your tastes (it has nipple shots but nothing else). This really feels like a show that is made for horny teenagers given the premise of the show and how horny every female character is towards the protag. The protag's scenario can't really be related too and you'll probably forget bascially everything about this show a few weeks after you watch it.

It's bad. I don't normally just say that first but this one warrants it.

Bad being subjective, let me follow up with the objective good. It has a proper ending. If you were into the show, and cared, it resolves the main plot issue of the anime. The others that it hasn't really touched upon yest are left open for further development. Unfortunately I seriously didn't care so YMMV.

The series big problems ?

It's a comedy that didn't make me laugh, NOT ONCE!!!!! . It did manage to put me to sleep so it may have some value there. There were opportunities but they weren't well ... used. I did watch it dubbed so maybe the humor was thee in the original Japanese and didn't make it over.

It's a romance ? Nah not really. I certainly didn't feel it. Maybe it was the whole setup of having the main character forced into the situation, maybe it was the fact the attempt of a mystery element overshadowed any possibility romance. Or maybe, it was just the fact that what passes for romance is, really weak.

Mystery ? I went with my first instinct and was right. Kind of killed it, but even if that wasn't the case it still wouldn't of been a good mystery. To make a mystery work, you need the riddle, you need clues, and you need motivations for the actions that make sense, and you need tension. There was no tension here. Can't say more without giving away too much of the structure. There was no real motivation for most of the key actions that were meant to contribute to the mystery. If the killer isn't a psychopath they need a reason to kill. Here you just kind of scratch your head. The clues are just annoying. You get clues, that are important, accurate and then invalidated for silly reasons.

The story fails on multiple levels. The hook is novel and interesting. It has an incredible amount of potential but there's just too much you have to overlook. No spoiler here, but at the beginning you are told, the father had been dying for 6 months and it's clear he wasn't comatose, yet the takes no time to convey information needed to his children, or provide for them, undercuts the premise. After that it goes down hill on trying to draw you in. As mentioned up top, the arc resolves, so there's at least that.

Characters. Shougo is interesting. He has his motivations, mostly acts believably in dealing with the insanity. Some of his reactions are off even taking into account the restrictions of the genre but that's hardly unreasonable. The other characters take 2D women to a new level.

The art is OK. Faces are distinct and expressive, emotions well conveyed. Backgrounds could be better. The artwork was meant to be a supporting feature not the star and it does its job.

The sound, oh the sound. The music was nothing special, but the voice acting was annoying. Most of the female characters sounded either weird, flat, or annoying, occasionally all three at the same time.

I'm writing this as someone who watches anime pretty exclusively to find brother/sister incest stories. I hadn't heard much about this one so I put it off for a long time, but I'm glad I finally got around to it. Although there are some stupid moments I could've done without (people pretending to be the main character's sister for no apparent reason), overall I enjoyed the show. I spoiled myself to figure out who the real sister was from the beginning so I could have more enjoyment from the start of the show (since I'm 100% not interested in the non-incest pairings), but your mileage ... may vary. For me though I was satisfied with the level of interactions the real sister has with her brother, and although the ending isn't totally satisfying, it's not as annoying as some.

The show suffers in the same way that many "harem" anime shows suffer in that women endless love the main guy, sometimes for really illogical reasons, and nothing is ever decided as to who he actually picks. I much prefer shows where a winner is chosen, but this one was fun enough, and at only 13 episodes you can get through it quite quickly. It's not a hentai so there are no nice sex scenes, but there are quite a few nude shots and lots of ecchi boob grabbing moments and similar.

Art and animation were pretty nice, though fairly standard. I really enjoyed some of the voice acting for some of the characters, Miyabi, Shougou and Kunitachi especially. The story line with Sagara seems unexplained/weird, but other than that I enjoyed it. I'd really like to see a season two, though from my understanding the continued story in the light novels gets very convoluted and I'd prefer the anime to maintain the relationships as they are at the end of the series.

Anyway, if you're looking for a somewhat light-hearted incest-positive anime, give it a go. You may not love the end results (incest is still frowned upon in this world), but the journey there is somewhat fun.

WELL this is one of those typical harem, shounen genre anime where the girls just fall straight into the protagonist's lap and love him for who knows what reason. (usually just because they do) Though this is one of the more poorly done ones. compared to say HS DXD or something similar that has more production value and time put into it.

Story: As described, the MC has to find a girl to marry so he can head his family by joining a school and searching for one, however rumor has it, his sister is in it and wants to marry him.. It seemed alright at ... FIRST, but then of course for the stupid reasons of course these girls fall for him, whether it be because of childhood, or just a random single date.. They also included "plot twists" which are so freaking retarded, I face palmed every time. It's a real pain to watch half the time. The only twist or mystery for the viewer, "can you guess who the sister is?"

Art: The only thing I did stay for is the fan service. I mean that's what these genres are generally about. (That and my friend begged me too.) The art is decent, the curves and whatnot I mean. I watched the uncensored version say YAY, there was one thing they could do decently.

Sound: I admit, I'm a massive 2D sis-con who loses it when they hear "onii-chan" in the cutest voice possible, this anime is just filled with it. It was good for a first few episodes but gets really annoying. (If you watch you'll see what I mean) The OP and ED are mediocre, what you would usually expect from these series. Nothing amazing.

Characters: Despite what I did say, they don't all for for him. More like half of them do, that being said.. Again they're al nothing special, typical characters, personalities, and you just pick your favorite. The back story's for these girls are't really worth mentioning either (I know this getting boring but bare with me!) HOWEVER the MC is a tad retarded at one point, turns in Ichika from IS at one point I SWEAR.

Overall: This is just fan-service, obviously not for a serious story, otherwise prepare to face-palm a lot in the process of watching this.

4/10 CREAMPUFFS.

I dropped this anime after the first episode. I mean seriously, he's getting girls by the minute, and these romantic situations are getting just plain old.

But alas, my love for harems continued to spring and I decided to give this anime another shot and I'm pretty glad I did. The latest episode explains everything to why the characters act a certain way and the plot is actually pretty good once you finish the latest episode. Trust me, nothing is that great about the anime until episode 4.

But, the anime still has its cons that make it not that enjoyable, but it still shouldn't ... get overally bad ratings by people who just watch the first ep (like I did before) since the plot and the story clear up later on in the story.

I can say without a doubt that this is the worst anime I've ever seen. I have to wonder, why did I decide to watch Nakaimo in the first place? I guess because the premise seemed interesting. Sadly, it turned out to be a total waste of time.
Story:
The premise of Nakaimo is pretty simple: a standard harem with one twist. Unlike something like Oreimo (where the protagonist knows who his sister is and is fine with dating her), the protagonist of this show didn't even know he had a sister (because of some poorly explained head trauma), and is doing everything he can to ... not end up with her, even though the sister makes it clear that she plans on marrying him. I guess the appeal of this premise is the mystery behind who the sister is, but with one look at the poster, I guessed who it was perfectly. Once that aspect is gone, you get a completely bland, forgettable mess. The pacing was horrible too. The harem has a whopping six girls (one who is added later), and within 12 episodes, they try to give each of them at least 2-3 episodes of focus and "character development". These episodes only exist to make you frustrated about who the real sister is. It's not spoilers to say that each girl is framed as the real sister at least once, and it's just annoying to see that be thrown around so much. I'll get into how that went later, but the pacing ended up a mess because of it, and any attempt at a story is buried behind a ton of worthless fluff. In the first episode, one girl is hit by a truck. There are no consequences or impacts on the story. It's just something that happens.
Art:
The actual animation wasn't that bad, but the art was a pain to look at. The character designs were bad and the quality was the definition of low budget, and that's not even mentioning the ridiculous amount of fanservice found in the worst places. Also, I don't think the animators knew anything about how things look. There was a scene where a girl's dress strap goes untied, which actually can happen, but the animation makes it look like some sort of invisible pervert was untying it behind her back.
Sound:
This is harder to talk about because I don't actually remember any of the OST (that's how boring it was). But, the opening was catchy, and that's probably the only good thing about the show.
Characters:
Take your standard harem cast, boil down any potential interesting character development, and you're left with the starch-bland cast of Nakaimo. The protagonist is so generic that I can't even remember his name, and he's the kind of character who acts however the episode wants him to act with no continuity to his "established" personality, which is the worst type of character. The girls are all standard tropes, but instead of being entertaining or having some sort of twist like characters in other harems, they get no development whatsoever. I mentioned that the show tries to give each of them a few episodes of their own, but those attempts always fell flat on their faces. The characters are boring and generic with no depth at all, and to top it off, they're not even designed well.
Enjoyment:
This anime was a chore to watch. After starting it and then neglecting it for weeks, I had to sit myself down and watch the remaining episodes in one go. Even if I liked harems, I wouldn't like this show. I mean, right before this, I watched Nisekoi (which I actually really enjoyed), so I guess I just got my hopes up.
Bottom line: this anime is a boring, generic, ugly waste of time. There's no reason you should watch it. Even if you're into fanservice harems, you're not going to find any enjoyment here.

Kono Naka ni Hitori, Imouto ga Iru!, is a Harem anime about Shougo Mikadono. After his father's death, he is left as the sole heir to the Mikadono Group. A large corporation which Shougo's father ran. In order to take head of the Mikadono Group, Shougo must find a woman he likes, and marry her. That's all the plot info you really need to know, so let's get onto the review...

-Story: The story of the anime is pretty original, the biggest twist, is the little sister. At the very beginning of the series, Shougo learns he has a step-sister on his father's side. He then ... learns that his sister not only wants to marry him, but goes to the same school as him. So, while trying to find a suitable bride, Shougo must uncover the mystery behind his little sister. The story in the anime is slightly better than mediocre for me. Of course, everybody has opinions.

Moving onto the Art; The show is not a masterpiece, but it's not terrible. The animation is fluid, and the style of art is nice. To make this paragraph longer, I'm also going to throw in this sentence, as well as the sound review. The sound is not too bad. Nothing really stands out to me. So I give it a decent rating.

Characters... Oh, the characters in this anime. We'll start off with the main character: Shougo Mikadono. As I explained above, he is the heir to a wealthy corporation and must find a bride by the time he graduates. I honestly can't think of words to describe him...
There are 5 candidates able to be Shougo's sister. Konoe, the cute girl, whom Shougo meets first. Miyabi, the Tsundere who loses her Tsun-. Mei (Sagara), the owner of little sister cafe, and tends to like cosplaying (Or just dressing up). Rinka (Kunitachi) the vice-president of the student council, and a true tsundere. Finally, we have Mana (Tendou) the president of the student council, and a happy-go-lucky, ditsy character.
Our final main character is X, or Ikusu. Is a girl, the same age as Shougo. At his school, she pretends to be a boy and passes off quite well. She is actually part of the Mikadono Group sent to help Shougo. She pretty much does whatever she likes, whether it be pretending to be with Shougo (Making people think he is gay) or parade around Shougo's apartment naked.
There are a lot of characters and some are pretty interesting.

My enjoyment I'd say is not too high. I prefer to watch it when I'm done watching all my other animes. This anime is filled to the brim with fanservice. From large breasts, of which the nipples are being covered by hair, towel or a shirt, to at one point, an incredibly short skirt. But, I expected as much from it. I'd say as far as enjoyment goes, 7/10.

Overall, the anime is a light hearted anime and should be treated as such. The amount of awkward social situations Shougo finds himself in astounds me, and amuses me at the same time. Still, I've seen better anime. Overall; 6/10

So this another harem ecchi show, so you already know that to expect from it. However, this show has following unique features
1. Kinda strong plot, because search for his Imouto will be one of the reason you'll look forward into next episode.
2. Nice humor, situation and character traits occasionally will take place during the show. If only there were more numerous.
