OreImo

Introduction

Kirino Kousaka embodies the ideal student with equally entrancing looks. Her grades are near perfect, and to cover her personal expenses, she works as a professional model alongside her best friend Ayase Aragaki, who abhors liars and all things otaku. But what Ayase doesn't know is that Kirino harbors a deep, entrenched secret that will soon be brought to light. At home one day, Kyousuke, Kirino's perfectly average brother, stumbles upon an erotic game that belongs to none other than his seemingly flawless little sister. With her reputation at stake, Kirino places a gag order on her sibling while simultaneously introducing him to the world of eroge and anime. Through Kirino, Kyousuke encounters the gothic lolita Ruri Gokou and the bespectacled otaku Saori Makishima, thus jump-starting an entirely new lifestyle. But as he becomes more and more involved in his little sister's secret life, it becomes that much harder to keep under wraps. [Written by MAL Rewrite]

A genuine subversion of the trope that maybe views better in 2026 than it did in 2010? I'm not sure what the huge negative push on this was back in the day but it really seems like it boils down to people just not clicking with the humor at the time, I was honestly shocked to know how old this was when I saw it, really holds up well. I think if you enjoy tongue in cheek self-aware anime humor you'll love Oreimo, if this self-aware humor feels like an attack on your "otaku culture" and you were expecting the alternate title to be the main focus of the series you probably won't.

A pleasant surprise. Was expecting more or less the common ecchi anime meant to attract guys with a little sister complex, but this anime is a little more than that, it's a love letter to otaku culture. Though I wish some aspects and points were explored more in depth, the message of the show shines through nonetheless: that this hobby that we all have is not wrong, but simply a part of who we are. The characters are nothing special, same for the plot as we follow Kirino and her misadventures. It might be generic but I still found myself invested enough to have a good experience. All in all I believe everybody should give this anime a shot.

Ive been stewing on what to write for this review for a long time... this show, its community and most of all its fans severely and potently confuse me. I hated this show it was a wreck and most importantly ive been sent down a never ending rabbit hole of ITS FUCKING AUTHOR, he is an anomaly, the world center for incest loving perverts, and i cant see any POSSIBLE REASON anyone would watch this unless to TORTURE AWAY THEIR SENSE OF PRIDE. i was embarrassed to watch this, not because the show was pervy or some sister-fucking train-wreck but simply because it has FANS?!?!?! Quite frankly, this show has nothing going for it, it is a show for fans of eroge, to think about making eroge while self-inserting themself into kyousukes position who IS LIVING OUT THE PLOT OF AN EROGE. it sucks, so ba…

OreImo is an anime where one of the main characters is obsessed with siscon visual novels and tries to share this forbidden love with her older brother. And he helps her do all sorts of things in this hobby space despite their father, who is not supportive of such things. Now the anime takes an implicit stand that such a hobby is not a bad thing for a person to be engrossed in. And my answer is no, being obsessed with anime/manga and siscon visual novels in particular is not a noble or good hobby. It's a hobby waste of time and money that is inferior to a great many productive and/or more intelligent hobbies. So I disagree with that point. Hardcore anime watchers are really just losers who can't find a better hobby. Now please read my 50+ other anime reviews on this website. Thanks. PS…

This is a classic highschool-romcom-harem series (eg: monogatari/oreigaru/bunny-girl-sempai etc.), where our boring MC who always had a boring life in the past, will now meet a bunch of girls and helps them with their problems. Warning: This is one of those "degenerate" series, so, avoid watching this with family. Also, the ending of this season is fake and you are supposed to see the ONA/special (4 episodes) which is the true ending that eventually leads to season 2. Plot MC has a really talented tsundere sister, and their relationship is awkward due to his inferiority complex. One day, he finds that his sister is a secret otaku and he starts helping her with various things like finding/making otaku friends or buy erotic games from adult shops etc. Of course, most people he will meet an…

Against all odds, this show is not about incest, depending on how you look at it... It is about a little sister who likes games and anime about incest. Ridiculous in its premise, Oreimo actively acknowledges the awkwardness of the situation through meta comments from the brother and sister, addressing the thoughts of the possibilities of incest in the viewers’ minds. However, the anime leaves it vague as to whether the connection between the brother and sister is a familial one or a romantic one. I will walk through the first episode to address the duality of the viewing experience and possible ethical dilemmas people may feel towards this anime. Kirino and her brother Kyou are not on good terms despite living together, in a middle-income Japanese suburban house, for a long time and being…

The pacing of this anime is nothing short of atrocious, rushing through episodes with little regard for coherence or depth. While it manages to evoke a few chuckles, its potential remains largely squandered. The premise had the opportunity to explore the fascinating conflict of an otaku girl struggling with her eccentric tastes, yet the plot conveniently sidesteps this, leaving a hollow narrative. The character dynamics, which should have been the show’s strength, instead feel mismanaged, setting up intriguing interactions only to leave them hanging, like a punch that never lands. Repetition plagues the series, with new plotlines emerging abruptly and vanishing just as quickly, devoid of any meaningful resolution. Growth, which is often the backbone of a short anime, is completely absent.…

OreImo My Little Sister Can't Be This Cute is a terrible anime about terrible unlikeable people. First of all the title "My Little Sister Cant Be This Cute" is a pile of BS. This little sister is the opposite of cute. Kirino Kousaka is the perfect school princess. But secretly she is an otaku. She especially likes eroge games. She keeps this a secret from everyone including her family and friends. But one day her secret is revealed to her brother. So now her brother must help her keep her secret. But also help her with her otaku life. This setup is all fine and dandy except for one problem: Kirino is the worst character ever. Despite her brother going out of his way to help her, she abuses him verbally and physically. And she is meant to be the main character...you are meant to sympat…

This is a review of the entire series Ok, explanation. Some stuff just gets plopped onto the To-Watch list simply because it was very prevalent in pop culture back when I first got into anime (remember when Haruhi was the mascot for every single anime site?) and as a result I have a semi-nostalgic attachment to the characters, despite knowing nothing about the shows they originate from. I knew full well going into this it was going to be a trash heap. But I'm 90+ anime deep for this year alone and part of the experience is finding the treasure amongst the trash. And I'm actually very shocked that it wasn't AS bad as I thought it was gonna be. Still trash, though. But amidst the piles of awful characters, terrible writing and despicable behavior are the remnants of what could've been a leg…

There are many questions in anime that have puzzled even the wisest of scholars. What IS the One Piece? Would Gojo win? Did Hachikuji actually stutter? And among those riddles, one stands tall. One stands above the rest. Is there possibly a way that Kyousuke Kousaka's little sister can be THAT cute? ...I actually thought she was fine? To be honest, if they REALLY wanted spineless wish fulfillment, they could have easily made Kirino some fluffball "do your best, onii-chan!" little sis but giving her some kick at least makes it seem like he's TRYING to fulfill a somewhat realistic big brother x little sister ship (...I assume, I don't have a little sister). Which I guess should bring me to a big warning flag in case you somehow are not aware: This is a story that is a big brother x li…

Oreimo or Ore no Imouto ga Konnani Kawaii Wake ga Nai is one of the more unique experiences in the anime genre. The first season is full of messages about relations, societal norms, family expectations, and etc. While the series can be seen just for its fixation on little sisters and the eroge side of the anime genre, a huge overlooked part of the series’ are its messages. These messages say things about parts of society, hobbies, and relationships/friendships. The convey experiences that are relatable and hard to miss.

 While the season does a great job in its messages, the fan service as a whole is over the top and can be a big deal breaker. This can make the story uncomfortable to watch especially when the subject of the season is the protagonist’s little sister, while this alone wou…

Man, this is the averageist of average shows. I'd set "mixed feelings" on this, but the main characters are so unlikeable I literally winced and took many breaks mid-episodes while watching this. The female lead is so entitled, full of herself and treats everyone like garbage - practically a trash human being. For every 20 minutes of treating everyone like absolute trash, she gets maybe 10 seconds of forced acknowledgement towards people who practically carry her every episode and even that is presented in a pretentious manner. It's not a tsundere, and it's not just tsun - it's simply being an outright b-word. I sure have seen a few of such anime heroines, but this one takes the cake as far as cringe goes. And then the male lead is no better, he practically is more of an indentured serva…

Oreimo is a piece of otaku media that I simply adore, even 14 years later after the anime release a lot of the weeb culture around it still holds up to this day. Truth be told, I wasn't always an Oreimo fan, this is actually my second rewatch. I first encountered it when I was 13, freshly new to anime. I hated it at first, I thought Kirino was a brat, Kyousuke being a weird obsessive sister freak, and I viewed the otaku culture around it as unpleasant. The only characters I liked were the main MC's friends (Ruri, Kanako, Manami, etc etc) but even that wouldn't convince me to change my mind. It was a weird otaku incest bait for me, and I had that thought for a few years. That was not until I decided to give Oreimo a rewatch this year. I don't know what prompted me, I guess It was just a s…

It's just so peak. A literally classic that explores how two siblings must fight against the taboos of modern society. The author brilliantly twists drama and slice of life into one of the most thought provoking pieces of Kino to ever come out of Japan. The supporting casts is of course diverse and colorful providing interesting tension as they get involved within the main characters' lives and dilemma. It is no surprise why this has become one, if not THE, most influential and recognizable non-shonen series of the early 2010s. If you call yourself an anime fan they you must watch this at least once in your lifetime.

Absolutely disgusting incest "romance" story written by a japanese hick and pervert about porn addicted siblings that end up marrying. The author of it has got to be on some sort of list, as will probably happen to you if you rate this show high. Unfortunately, the first anime I watched a very long time ago and at a young age too. Only "saving grace" is the opening song and good looking characters, which is why anyone could find this show appealing. Even then their personalities are horrid. That is to be expected, as there is no plausible way to make a healthy and adequate story out of degeneracy and incest. Save your sanity, I wish I did when I was a young teen.

Smilomaniac

This show is entirely an author's self indulgence. This is indirectly confirmed in this show and the 'alternative ending' special (which I'm including in this review), where an emphasis is put on creators wanting to put out what they like even if it doesn't please people, even if it messes with editors, directors, producers and anyone else who wants a piece of the pie. I think this mentality is extremely admirable and we need important examples of passionate art and entertainment to contrast to the massive overload of remakes and sequels that saturate theaters, TV and streaming services. Problem is, you need to actually put out a competent product and this is not that. The hook summary is that Kyousuke has a little sister, Kirino. He's your average 2nd grade non-descript high schooler…

This probably doesn't need another review given it's popularity, but just in case... Oreimo isn't nearly as bad as what the haters and negative comments suggest it to be. If you want something cute and funny to watch, this is definitely one of the better romances to get into, and I will always recommend it. People are likely only disappointed because of its ending, which I will say right here is an extremely fair and understandable point. I too absolutely hated the ending. But, if you think about it, there really was no way to give it an objectively ideal ending. And to give a low rating just because of this, is unfair considering all that it delivers. Let me get something out of the way for those who might still be on the fence - the title is extremely misleading. Yes, it's about incest,…

Utter garbage. Abandon all hope that it'll get better or there will be character development. Main character has zero backbone and will get hit and verbally humiliated nonstop even though he constantly goes out of his way to appease the most obnoxious, egocentric, annoying character in all of anime history: Kirino (his sister). Even if this show had a good plot it would still be unwatchable due to how infuriating she is every time she takes up screen time. This show would at least make sense if the main character was a masochist or a GOOD explanation existed for why he keeps eating the shit his sister shoves down his throat (and comes back for seconds). And no she's not a tsundere, shes just a spoiled brat. To conclude: -Boring plot -Annoying characters -Cringe comedy -Cheap animation Don…

actually the story is good but i don't know why i hate kirino and ayase seeing her pisses me off sometimes, they are only selfish and don't know themselves, even though Kyou has helped them many times, but they are still considered trash, but the MCs in the anime look stupid and cowardly and only follow their wishes. it pisses me off a lot and in my opinion the story is a bit boring just watching his older brother follow the wishes of his younger brother who doesn't know himself, the art style is suitable, the storyline is a little unrealistic in the real world only a little in my opinion I think just watch it if you are curious

we're not traumatized by decades of extremely rapid social change what are you talking about. this is a good industry. and on an unrelated note we think cartoons can show you that you have to have to kids (modestly) to restore the platonic ideal of our society. PLEASE PLEASE PLEASE have kids so we can go back to thinking "unskilled labor" "being not from the city" and "part time employment" are socially acceptable things. it can be your sister if you need it to be. please. NOTHING is wrong there was no war there was no bomb its always been like this your memories are lies there is no 30 year long recession slowly corroding everyone and everything under the metal heel of a smiley-faced capitalism death drive nightmare engine (america also has one but it wasn't polite enough). everything is…
