The series are both written by the same author and share the same animation studio as well. Both anime are romance comedies focusing on the relationship between the main character and his younger sister. In both shows, the brother finds out a secret about his sister which leads to him talking to her for the first time in years. You'll probably like both the anime, if you enjoy watching lighthearted comedies and anime focusing on little sisters.
For starters there done by the same writer, but also they have practically the same vibe to them. Both feature
A tsundere sister who is in love with her brother (Happens later in ore no imouto, sooner in Eromanga)
A surprisingly patient main character who takes alot of crap
Both are also have a harem vibe to them without executing it properly
In a whole i would say Eromanga is better since i dropped ore no imouto because it bored me.
Either way if you came for the incest kinda vibe you will like both
-Both Protagonists have sisters with weird hobbys.
-Both Protagonists, in a way or another, discover this and had to keep it as a secret.
-Both Sagiri and Kirino have the same plushies in her beds. (Not relevant but interesting)
Both series feature a brother-sister relationship.
In both anime the sister has an unusual hobby for girls her age (in OreImo it's playing little sister eroges; in Eromanga-sensei it's drawing erotic LN art)
The source material for both is written by the same author and have the same character designer.
The studio resposible for animating Eromanga is the same that animated the second season of OreImo.
These are pretty much the same thing; characters from OreImo even appear in Eromanga-sensei:
- Written by the same author
- Both feature a little sister love interest
- Self-aware comedies
- Both little sisters are closet otakus and perverts
- Both take a look at otaku culture
Eromanga-sensei is the spiritual successor of OreImo. Seriously, they are frighteningly similar. If you (somehow) liked either show, you will 100% like the other.
Eromanga sensei is the living reincarnation of Oreimo. Both MC's in the show are very caring towards their younger siblings or let's just say they very much love their cute and loving little sisters. Both the shows involve an incest relationship although in Eromanga-sensei, they are step-siblings and they're the only ones in their house because their parents was involved in a tragic incident. Both shows are great but if you want a deeper and a better plot, I'd recommend to watch Eromangaa Sensei.
Not ignoring the fact that both have incestual themes, both focus on the interior relationship, Oreimo and Eromanga-sensei live in the same world, Oreimo made a cameo in Eromanga-senseiand vice versa, it has a good promising ending.
Overall just a (short) copy of Oreimo with a flip and lots of fun twist.
Pretty much the same theme. Brother and Sister relationship. The sister is a complete tsundere to her brother. The MC got a lot of woman around him but chose to stick with his sister. Even the Light Novel writer is the same guy. Watch this if you like Eromanga-sensei but wants it for a bit older character (At least the character here is a high schooler not some middle-schooler).
Two shows from the same author, with somewhat similar casts (I swear, you can almost one-to-one match up the characters between the two). They're a bit absurd, but there's some humor in watching them play out.
The same author wrote both of these, for one. Eromanga-sensei is a lot like Oreimo, but toned down a good bit, for those people who aren't absolute siscon filth like myself (in anime or anime related forms, I'm not gonna take the incest route IRL)
Think of Eromanga-sensei as the softcore version of Oreimo.
These two are so similar that the OreImo cast made a 'from behind' cameo appearance, in episode 11 of Boku.
Kirino and Sena are the same character... breasts aside. Their spoiled princess attitudes, erotic game addiction, prideful arrogance getting in the way of friendship and fangs are NEARLY IDENTICAL. What's more, Kuroneko and Yozora ALSO MIRROR EACH OTHER--sharing 'bickering love' friendships with K&S respectively. They argue CONSTANTLY when together, oblivious to the how similar their personalities are. The only difference of note in the relationships between the shows is that Yozora clearly has the upper hand against Sena--often forcing her to run away, crying. THERE'S EVEN A GUY IN THE LOVE-TRI MIDDLE, IN BOTH SHOWS!
The episodic content is VERY familiar, also: making friends is central to Boku's story but even OreImo had an episode about trying to make friends. And both shows deal heavily with otaku/gaming jokes. read more
The art is similar and both have many things is common.
The constant fighting between Yozora and Sena remind me a lot to Kirino and Kuroneko (and the personalities are also similar, as the fanaticism that Kirino and Sena have for the eroge).
In short, if you like "OreImo" you'll like "Boku wa Tomodachi..." as well.
Similar comedic formats (one male straight man, two females who argue constantly but are united in harassing the guy)
Also, similar themes about being true to yourself and learning to accept your own quirks.
Both animes are made by AIC Build. Also, in both animes, there is moe, a girl who likes ero-games, a girl who dresses in gotchic lolita dress no matter what weather, and a otaku girl who wears glasses.
Both are also seinen series, and have harem in them.
Similar comedy style and both series have a girl obsessed with eroge.
Both animes try to address certain problems in today's society. Oreimo deals with the problem of being an otaku while Haganai focuses on the issue of making friends. While neither are particularly educational, they both offer hilarious moments and sometimes emotional moments.
Both shows have a similar feeling--lightly harem, lots of otaku-oriented references, mostly about character and relationships, not too much high-concept and nothing supernatural. The theme of acceptance is very strongly presented in both shows. Both are primarily comedy with some dramatic moments. Both have sequels that differ in quality from the original (except that Haganai's sequel gets better, and Ore Imo's gets worse).
oreimo and haganai both share characters with similar personalities. in oreimo, the main character is a teen girl who has a obsession over eroge which is similar to sena in haganai. the two stories are also simlar where the 2 main character has a friend they fight alot with, for example , krino and kuroneko , sena and yozora.
Both animes are very similar.
In both animes there is a guy and a girl that are both getting close in relationship.
Both MC has supports of their closest friends.
Both animes have a bit of ecchi.
Both animes were written by the same author.
p.s. You can see in Boku Wa Tomadachi ga Sukunai Oreimo characters.
The anime are both light novel adaptations made by the same studio. In both shows, the protagonist helps a girl make friends which leads to him meeting several other girls. The main heroine also ends up as rivals with another girl in both anime. The shows also hint at possible romance developing between the characters later on. The series are worth watching if you like slice of life comedies or anime that deal with the otaku culture.
A popular school idol hides her otaku hobbies, which a normal boy finds out. They spend most of the show hiding this secret and doing various otaku activities. Haruka has a romance element that OreImo is lacking, but they're pretty similar shows.
Both Oreimo and Nogizaka Haruka no Himitsu have the idol-like female who wields good looks, talent, and many fans. However, they have a dirty little otaku secret that is discovered by the male lead. The male lead promises to not only keep their otaku side a secret, but to support them as well. Oreimo lacks the romance aspect Haruka no Himitsu has, however.
Both series adapts the theme of a young girl who is into anime despite being cute, admirable, and popular at school. She tries to keep it a secret from others besides the main protagonist in the series who knows about her hobby.
Both series' protagonists has a strange relationship but does get along well on occasions.
Both series are lighthearted that has romance, comedy, drama, and similar themes.
They are largely similar in many ways, except Nogizaka Haruka no Himitsu has a romantic theme while Ore no Imouto ga Konna ni Kawaii Wake ga Nai is not (or is it?), not much to say about this one, if you like one you should like the other.
The main girl is a "closet otaku", she need help of a boy for hidden her secret.
in oreimo, the main girl is "tsundere". In Nogizaka the main girl is "princess-dandere", both have a lots of Fan-service, but Nogizaka is more ecchi than fan-service.
Both female leads are trying to hide the fact that they are otaku's from the others and they end up being discovered by the main guy leads that are voiced by the same actor. Both female leads have more than enough money difference is one tsundere and the other one is shy and kind
These two anime's have a similar concept of the main heroine getting her secret revealed by the main character which is a guy. The main character then helps the main heroine to keep that secret so no one else will know. These two are very much alike but can be different in many ways. If you like Oreimo or even disliked it then this should be the anime for you it has less drama and it has a lot more romance in addition it seems that there are less major problems. Overall Nogizaka Haruka ni Himitsu is the anime for you if you enjoyed Oreimo or any other anime. read more
Both anime explore the otaku culture (more specifically the gaming aspect of it). The main characters are often shown to be playing visual novels and seemed to be addicted to them. They are also both knowledgeable when it comes to these kinds of games.
Both feature an MC that's completely engrossed in dating sims and the likes.
Both often prefer the 2D world over the 3D world.
Both have romance in it but The World God Only knows focuses on that more.
If you are looking for a similar show about otaku culture, this is it. Whether it's to laugh at the main character's obsession with the hobby or secretly envy the devotion, just having enough "knowledge" to watch her (Kirino/Konata's) actions and understand them makes it a fun experience. However, their paths along this nerdy road are quite different so it's also nice to look at it from the perspective of someone who has the support of most of his friends and family and one who doesn't really have to courage to come out. Lots of references, tackling of shady subjects of pop culture and great supporting characters. read more
Both series has a Brother and sister setting. Both main heroine are Prodigy of their school (Doma Umaru and Kousaka Kirino) but inside they are actually an Otaku, and the only person who knows is their brother (Doma Taihei and Kousaka Kyousuke).
I don't really like Kirino's personality toward his brother, but its a great series which I can compare to Himouto! Umaru-chan. Recommended for Comedy fans!
Both female protagonists are popular, beautiful, and charming high school girls. But are actually closet otakus, devoting their lifestyle to it. Both have tsundere tendencies towards their older brother, while at the same time bonding over activities such a video games. Both also have diverse groups of friends who have to struggle maintaining their home and school life with.
Basically about a perfect imouto on the outside but is in reality a shut-in. It follows the daily lives of them trying to hide their identity. OreImo however does have a side plot, with a much wider cast. Both of them has a storyline and connection, yes, even Umaru-chan has it. Also the imoutos are annoying in both series. Finally, there's a sub genre of romance although again, in OreImo it completely takes over.
OreImo has better storyline but Umaru-Chan has better comedy and SoL elements.
If you are sister-con, you will enjoy Oreimo and Umaru-chan, as both series have a younger sister and an elder brother as main characters.
Kirino and Umaru, the heroines of two series, are both perfect top students at school but actually otakus at home, while only their brothers, Kyosuke and Taihei, know their true sides. If you are an otaku like Kirino and Umaru, you may have the same feeling as them and enjoy the comedies about their daily life with their friends.
The anime are both slice of life comedies focused around the relationship between the main character and his younger sister. Both of the sisters act like perfect girls at school but are secretly otakus at home. OreImo is more plot heavy and has romance in it while Umaru-chan is mostly slice of life. If you like lighthearted comedies and anime focusing on little sisters you'll probably like both of them.
Both have to do with an older brother taking care of a younger one, just one doesn't have sibling romance.
Umaru is a bit more animated in terms of expressions of the characters. Storylines are not very similar at all, but if you like sibling anime, then you'll probably like this one.
Both animes got a male lead who does everything for the bitchy girl (sister/friend). Ummm, don't really know what more to say. The are very much alike so if you like one of them, check the other out. =)
Both animes star an energetic, near-perfect female lead character who is both lovable and annoyingly confident at the same time with a laid-back male lead character to pick up the destruction in her wake. Though the events in the animes primarily revolve around the female lead, the story is seen from the male lead's point of view.
The protagonists in both series are extremely talents in everything they do - whether it's studies, sports, or learning new things.The personality for both character are also similar - close to the tsundere archetype (though Kirino is not as dere-dere). The male leads are both caring and responsible figures, but they both have to endure the hardships imposed by the female leads.
Watashi is the OreImo only reality can offer. What this means is Watashi's sister heroine isn't beautiful, isn't an athlete, isn't at the top of her class and just generally doesn't have the world at large fawn over her. In OreImo acting bitchy whilst having a sexual fetish typically associated with fat otaku men is rewarded, and the icing on the cake is a doormat brother willing to do anything to appease her--incest not withstanding.
OreImo delivers as far as entertainment goes. This is true. But after following Kirino's tsundere self down the road toward incest for long enough, it makes a nice change of pace to see Watashi's socially awkward sister heroine have to practically blackmail her brother into just talking to her as she deals with being a weird outcast in comical fashion.  read more
In both series, the main female character is considered an otaku of sorts with a habit of playing games alone by herself. (Their popularity with the outside world is vastly different though.)
The main male protagonist is the brother of their sister, and they have opposite personalities. The bothers also share the same VA.
Both series make fun of the otaku culture, have catchy dialogues, as well as have the ideas of growth and relationships with family. Both series also have a school-life setting filled with drama and comedy.
Both series involves a female main character (Kirino/Tomoko), who loves play videogames and other otaku stuff. Both girls wants to make friends, but there's the difference between both girls: Kirino is a pretty popular girl who wants to make otaku friends, while Tomoko is a lonely unpopular girl who just wants to make friends. Under their own situations, both girls has to appeal to their brothers (Kyosuke/Tomoki). Both brothers have an average attitude, but Kyosuke tends to be more careful about Kirino, while Tomoki doesn't seems to care about Tomoko
The main females leads in both animes are otaku and play dating sims.
Both main females want friends ( in Oreimo though she wants Otaku friends).
The brothers of both main protagonist have the same actor and act similarly.
Watamote and OreImo have two strong female leads that are almost opposites of each other but share the same interests.
OreImo's Kirino is a cute, popular and smart girl who is secretly an otaku and gets no greater pleasure than playing the eroge and watching the anime she loves. However, she must hide her hobbies for fear that people will shun her if they find out.
Watamote's Tomoko is an unpopular, slightly odd looking girl who is socially awkward but desperately wants to be popular. She, too, loves anime and dating sims, just like Kirino, and is more open with her love of them.
Both series have funny and adorable brother characters, although, in OreImo, it's an older brother and in Watamote, he is younger. In Watamote, Tomoko's younger brother, Tomoki is more popular than her and she has to pretty much blackmail him into doing what she wants. However, Tomoki and Tomoko shared a close relationship when they were younger, as seen in many flashbacks.
Kyosuke is Kirino's older brother and he considers himself to be completely normal, which makes conflict with his much more extraordinary sister. Kirino ends up blackmailing and coercing Kyosuke many times as well, though it is later discovered that Kirino looked up to her older brother immensely when they were young, also seen in flashbacks.
Honestly, I'm shocked these two don't have some studio, directer, author or producer in common, and though I could be wrong, I have yet to find anything that connects them. Though these two anime look different on the outside, at their core they are very much the same.  read more
these shows deal with incest. if you liked one, watch the other, you won't regret it senpai
both have mature older brothers and cute little sisters. these shows will both make you cry. oreimo is more neorealist while koi kaze draws inspiration from mono no aware and modernist artists.
also similar music
watch it senpai
They are both incredible, heart-rending deconstructions of the incest subgenre of anime.
They vary in the degrees of deconstruction, as Koi Kaze goes for a premodernist, straightforward approach, while Oreimo is a subtle, neoclassic take on the romance between siblings.
Prepare to cry when watching both shows.
Ahh, is there anything nicer than true love between true siblings? No, and that's the truth.
Both series feature incest as a major theme. It could be argued that the way they tackle this theme is maybe just a little different, but hey let's not get caught up on semantics. Fans of one will certainly find much to like in the other.
Koi Kaze and OreImo both delve the issue of sibling love. It is one that is a socially rejected concept and at the same time glorified by ethics in anime journalism.
If I were to compare the two, it'd be using my expansive knowledge of porn, particularly between two-dimensional characters. There are many doujins involving tags such as, but not limited to, "lolicon", "incest", "schoolgirl". Although they are projected through the same media, the direction of the works can vary, into even the "netorare" tag. Likewise, Koi Kaze and OreImo are both under the same umbrella, yet mechanically different. Koi Kaze is reminiscent for La Nouvelle Vague, while OreImo is avant-garde in its own way, conforming to the social standards of our time.
However, I digress. Essentially, they're both tales of the life between a brother and sister, with the flames of passion propelling them. read more
these anime both about building romantic relationship between a old brother and his sister ( incest ) however ore immoto kawaii.. is funny and more comedy and koi kaze is more drama oriented. i liked them both recommend ore immoto kawaii more
Do you enjoy stories about romance between siblings? Do you enjoy stories about tragic yet beautiful love blooming between two very different people? If yes, then you will enjoy Koi Kaze. The story is dramatic and focuses primarily on the relationship between estranged siblings. If you enjoyed the romantic and incest aspect of Oreimo, you will enjoy Koi Kaze.
Two anime with prospectively the most epic titles are all about incest.
OreImo is about a younger sister and her friends trying to get into an older brother's pants, or at least that what we wish to see in the show.
Non-OreImo which I don't know the official abbreviation of its title is written by former erotic manga writer. Story isn't its strongest suit, unique art direction in manga is non-existent in anime but you are still suggested to watch this if you loved OreImo. They both linked together by incest.
Well Lets see.. They both have that "incest" Vibe to it. Although, I do think that OreImo Has a more sensible relationship between the siblings and actually has some sort of story. Onii-Chan no Koto goes abit overboard with the whole Incest thing. Also, it's animation is abit... Strange? OreImo Revolves around the relationship of the brother and sister and the whole otaku culture. Where as Onii-Chan no Koto revolves around more sexual jokes, stronger incest content and this strange harem. Personally, I enjoyed OreImo more than Onii-Chan no Koto, But im sure if you liked one, you may enjoy the other.
First of all, both of these series contain the theme of otaku and its life style. It is a hobby in both series and a way of life.
These two series also contain drama, comedy, and presented in a way that is influenced by the culture of otaku. Both series also has a strange cast of characters of stark personalities that makes the story fluid and enjoyable.
Genshiken is another anime to talk a lot about otaku culture. It's less focused on romance, and there isn't any sibling drama, though. There is, however, still SOME romance. In Oreimo, you have Kirino and her otaku friends, but in Genshiken, you have an entire club of otaku who do similar things to Kirino like playing games, going to Akihabara, and going to Comiket.
Both shows deal with otakus and otaku culture around them. While Genshiken delivers a much more realistic approach, OreImo shows a more idealistic approach
Both shows also have traces of romance in them, where Genshiken is once again a more mature approach while OreImo is a more incestual approach
Two shows that own the distinction of doing the tsundere character correctly, which is less common than most people think.
Orange-haired Tsundere female protagonist who drags the blue-haired levelheaded male protagonist into her hijinks. Very similar tone and surprisingly good pacing, with a small but strong supporting cast.
Both have unique styles, both have intriguing Main and Supporting characters, both have brilliant female tsundere leads as well as very original male leads, both are very funny and yet very emotionally touching.
I seriously sometimes think that they are in the same universe. And like to believe it.
Embracing the otaku culture, having life counseling, and other crazy stuff. OreImo just faces more on the girly romance side while NHK ni Youkoso tackles things that a hikkikomori does and what they think are true "conspiracies".
Ore no Imouto => Welcome to the NHK
Both have Otaku issues integrated and dealt in the story. While OreImo is more light and focus more in the setting, NHK has a more psychological, personal and dark takes.
Both reference otaku culture a lot and involve the character getting help and counseling. OreImo is definitely more light and NHK is more psychological. They both are pretty funny though, if you like otaku humor.
Both of them deal with hiding a secret passion of "special" Likes from the rest of Society
Also both have a "Dark Power" Character, if i shall call it like this
Also both are Comedy and Slice of Life Animes
Both main characters have a hobby that they try to hide from other people. Both series are comedy, although Chuunibyou is much better and smarter in humor, and also in the development of characters. The theme and atmosphere are similar in both series is school and otaku style.
Brother-sister incest is the topic of both titles, although OreImo takes a more calm and quasi-serious approach while OniAi is almost exclusively comedy and fanservice. Both involve the pressing question of whether fiction is indeed separate from reality (Kirino's eroge and Akito's novels). Both also feature other girls who, together with the younger sister, form some degree of a harem. Kirino and Akiko are also similar in their iconic perverted-ness.
Both animes follow the concept of little sisters. Though the little sister's personality is flipped in Onii.
Many people may find Onii to be less enjoying compared to the mass favourited Oreimo. You can sense some kind of weird incest sh*t goin on in the title already.
BUT some others can find incest enjoying in anime, therefore you may find the romance you want between the sibling leads that you did not find in Oreimo.
Instead of a conflict and tension between siblings , Oniai is the opposite, the little sister is in love with her brother. while in Ore no Imouto ; the little sister pretty much hates her brother I think. Anyways I think if you like Ore no Imouto you're gunna like this anime.
The story follows two of the main characters (a brother and a sister) who usually have a brother/sister complex throughout the series. It can be either love, hate, or usually annoying when it comes to these complexes. However, deep down, they still care for each other, no matter what they do or wherever they go. Situation arises, when another person (Mostly a girl) got his attention instead of his sister.
Oniai is basically a fan service show where the sister has a brother complex, while Ore no Imouto, the sister is usually a tsundere towards her brother and mostly an otaku girl.
Both are comedy, harem, slice of life anime that present the events from the perspective of regular otaku doing otaku things.
In each of them there is that one character that after being compelled by the other otaku characters they become fans. There is also the blonde tsundere that writes novels/doujinshi and tries to hide the fact that she is an otaku, the rival writer, the idol and the blogger.
In both the characters try their hardest to enter the industry. In Saekano the story is based about them creating a VN. In OreImo this is not a main theme but they also face challenges in this domain. read more
Both are harem anime about otaku culture. If you like Oreimo, you would probably like Saekano.
- Oreimo focuses more on comedy, Saekano focuses more on romance
- Oreimo views the Otaku culture more from a consumer standpoint. Saekano more from a creator standpoint.
In Oreimo, we follow our mc Kyouske and his three different girls(I think), with one in each arc. On the other hand, Yosuga no Sora also has different arcs but with more... ecchi *cough* *cough*
Both titles are about typical high school boy and his harem, including little sister. Every female heroine has its own arc, but the main is incest one. As for Oreimo, it's more a romantic comedy, and Yosuga no Sora is a drama about forbidden love.
Same type of love story, which is incestual relationship between brother and sister. While in Yosuga no Sora it is described in a serious way, in Oreimo, it's more focused on the comedy side.
The unfolding of the two anime is similar: the protagonist is surrounded by several female characters who all serve as love interests. But the main girl remains his sister, who is jealous of her brother's suitors.
Also, each girl has her own arc. However, the final arc is in both shows focused on the little sister.
One of the main characters is a blond-haired, blue-eyed middle school girl who really likes a particular magical girl show whose main character has pink twin-tails to the point of vaguely implied shoujo-ai on the part of the fangirl. The plots of each series are completely different, but it's an odd enough similarity that I think it's worth mentioning.
Anime that focus on the interactions between older brothers and younger sisters. These would be enjoyable especially to those of us who are in fact (responsible) older brothers in real life.
*Watch Bakemonogatari first before starting Nisemonogatari.
haah these 2 shows just look exreamly similar their characters loko almost exactly alike the 2 girls also look alike with the same hair color. in my point of veiw the main guy is similar in ways in both they both have sercreats that they try to hide from each other and cant expose it to the world easily
both about an orange haired girl and a blue haired boy.. the girl is super populer.. one of them have a problem and the other character is trying to solve this problem.. both are comedy.. and there are few scenes with the exact same point.. and the guy desovers the girls secret in the first few episode and always tryes to hide it from others..
This doesn't have that step sister and brother relationship plot but in return a full-blood sibling incest love between brother and sister, which of course the sister is a complete tsundere.
Note: I'm talking about Ore no Imouto here where it's the incest.
Both series are comedic and of the slice of life genre.
Both series' main male protagonist are good at giving advice, with the drawback of either being hated or losing their dignity.
Both series somehow or somewhat reflect certain real life situations.
Both are very similar in many ways, although completely different plots. First, both are ecchi, harem, comedy, and school. Both main characters are put into situations to be surrounded by girls. Both have to do with having an otaku life vs real life. Both have tsundere female with light hair. The main difference is that Netoge is more gaming orientated and Oreimo is more anime orientated. But in they are very similar even when it comes down to the OP, which sounds remotely the same.
Anyone who enjoyed watching Oreimo will definitely enjoy watching Citrus, since Citrus is basically Kirino's dream of having a little sister come true. Kirino and Yuzu, the protagonist of Citrus, have almost the same exact voice as well as similar styles, so it's rather easy to imagine Yuzu being Kirino.
Oreimo's main characters are two blood-related siblings who had a falling out that come to love and trust each other again, eventually leading to romantic feelings between them.
Citrus's main characters are two girls who become step-siblings that learn to love and trust each other, leading to romantic feelings between them.
Citrus leans more on the drama side while Oreimo is more of a comedy with drama sprinkled in. Both are heavy on relationship development between the two characters. Citrus is more romance heavy. Both don't shy away from their 'sibling love' content. Kirino (little sister) from Oreimo and Yuzu (big sister) from Citrus are voiced by the same actress. If you are a fan of these types of relationships in anime, you should like both.  read more
In both series main characters are girls who have some kind of specific problems.
I can even say that they both are of tsundere type.
In fact, they're alike in physical appearance.
And those girls have complicated relationships with male main characters who are ordinary guys in general.
Both stories are harem romantic comedies with harems with a brother x sister relationship at the center.
In Oreimo, the sister is an otaku.
In NAKAIMO, the brother doesn’t know who his sister is.
NAKAIMO is much more ecchi.
NAKAIMO is one season and one OVA, whereas Oreimo is two seasons and six OVAs
Oreimo and Shoujo-tachi both focus on game/anime culture.
In Oreimo, Goku Ruri (Kuroneko) together with her friend also made a game, also she is a writer, whilst in Shoujo-tachi, Sayuki asked Buntarou to create one themselves.
Both have a very similar humor style, though both shows actually have more serious elements to them despite being comedies. Both seem to be a bit more suited to more adult audiences though, if you dont mind a little fanservice and cheeky humor then you cant go wrong with either of these.
Both of these shows have a similar style in humor revolving around a romance based plot. They contain many of the same themes while each remaining unique. In both shows, manga, anime, and games are a major point. If you enjoyed either one of these then give the other a shot.
They both have the happy-go-lucky, cheerful air about them. Cute characters with sweet storylines make for enjoyable shows, and both Papa no Iukoto and Ore no Imouto have that! Lots of laughs and touching moments.
Someone will probably give me hell for making this comparison, but they both have a relate-able main character who goes out of his way to help a (few) girl(s) with their problems, a tsundere female lead who undergoes a surprising amount of character development, and it would also seem both main characters share an... interesting relationship with their little sister(s, in Araragi's case), although I haven't seen Nisemonogatari yet. Both shows also seem to occupy that odd space between a harem and non-harem series, with Oreimo standing extremely close to the harem side and Bake taking a similar spot across from it.
Oreimo's strength lies in the development of it's characters, while Bakemonogatari has a generally more likeable (but less developed) cast and a decent story (although Oreimo really didn't need one). Bakemonogatari is definitely the better of the two, but if you enjoyed one of them, you will probably enjoy them both.
Also of note: Bake has one absolutely godly ending theme and several great openings while Oreimo has one nearly-as-godly opening and several endings (which I didn't really find special). read more
Maria Holic has Mariya using Kanako to keep his secret of being a boy from being found out while Kirino from Oreimo uses her brother Kyousuke to keep her secret of being an otaku. Both are also comedies.
Naturally, Index and Oreimo are both different kind of anime (Oreimo has a realistic comedy plot, Index has a futuristic fantasy plot). But in both series we have a normal young main character (Touma / Kyosuke), a guy who uses to be very quiet and tries to help his friends to any coast, specially women. However, this guy often has to deal with a tsundere girl (Misaka / Kirino), who usually annoys him and doesn't accept his "womanizer" lifestyle. Oh, and both girls tries to hide her childish likes
What does it mean to have a sibling you can count on? Someone you can share your darkest secrets with? Someone who accepts everything about you, no matter how taboo? Well both Pupa and OreImo answer these questions in their own ways. Despite the stories being different, the theme of sibling bonding, the importance of family, and accepting those you love for who they are are the driving forces behind both.
-both anime took place in their respective schools.
-The story line is almost similar, the choices of the main male character and the ending is also similar
-Endings are almost the same but photokano's ending is different from Oreimo
-Both Romance, School, and Comedy genre'd animes
Both have incest (if you're into that?), adorable characters, comedy, and they are just great all around. Note: Kirino from Oreimo is the worst piece of trash to be placed on this earth as a character and needs to die. Kuroneko from Oriemo is absolutely great though.
Both shows have the theme of the average brother with the overachieving little sister and revolve a lot around the brother providing help and support to his sister
Both of the sisters are similar as well in that they both show ample tsundere personalities, although where OreImo it took a while before the sister realized her true feelings (or at least it took a while before it became present to viewers) I Love My Sister it's revealed from the beginning that the sister has feelings
I don't know how no one noticed the similarities between the two series. Both focus around a love triangle between main character, sister figure and third wheel girl. And in addition there is an additional girl who the protagonist won't even acknowledge. Well, the only difference here is that, in True Tears, the siblings are not actually related by blood (despite certain implications that it might be the case).
Kuroneko fans, rejoice: your waifu may be no match for incest but in Gate her more sadistic, raunchy clone returns to anime and is seemingly determined to kill men with a huge axe. Hell hath no fury like a woman scorned?...
In all seriousness: I refuse to believe Rory Mercury from Gate is not based on Kuroneko from OreImo. THEY EVEN HAVE THE SAME NAME: Rory / Ruri! To be more precise, Kuroneko from OreImo looks and acts like Rory whenever she is cosplaying as a 'GothLoli'; complete with a haughty / condescending-but-playful persona. All Ruri would have to do is cosplay as her namesake from Gate and, BOOM: samesame.  read more
Both anime have a lot of fun characters, including older brothers who look after their little sisters! OreImo references a lot of otaku culture whilst Sasami-san (while doing that as well) mainly references Japanese mythology, but I think Sasami-san is thematically close enough to OreImo that every OreImo fan should give it a shot.
A non-assertive male lead finds himself getting pushed around by a tsundere female lead.
Also, both male leads have a sister who is a bit of a brocon. However in Oreimo, said sister is also the female lead, while in GJ-bu the sister is a supporting character.
Both start off as fairly lighthearted and innocent anime but quickly delve into more serious themes such as incest and pedophilia. Even though they are dealing with these mature topics, they never take things seriously and instead entertain with their quirky characters and comedic situations. In addition, both plots feature an unsuspecting male lead who suddenly has to take care of a girl desperately in need of his help. Overall, both have very similar vibes to them and I think that if you enjoyed one you will likely enjoy the other. Hell, I think Sankaera could easily be called "there's no way my little zombie could be this cute". read more
While the setting is completely different the dynamic between the two main characters is quite the same (girl hostile, treating the boy as a slave, boy acting kind, caring and protective for the people around them, even though being annoyed by getting treated like that).
Also the development of their relationship and the relationships around them shows a lot of similarities (recognizing the true feelings towards each other, making friends together, watching out for each other and so on). The people they make friends with are different and not comparable, though.
It feels quite the same when watching these two animes.
-Both female leads are tsunderes.
-In Oreimo, the male lead is hardly involved in the life of his sister until he discovers her secret, and then he ends up supporting her and saving her on multiple occasions even though in the beginning she would have never imagined that he would do that.
Similarly, in Ookamisan, the female lead had the male lead pegged as a coward and never once considered that he might be the one supporting her and saving her, but he surprises her by proving her wrong.
-Both are comedies about high schoolers.
When I saw the episode 0 of "Boku wa Tomodachi ..." reminded me a lot to "OreImo".
Perhaps because there are "girls gamers", and art is a bit like, not counting the confrontation between the two heroines: Sena / Yozora (Boku wa Tomodachi) and Kirino / Kuroneko (OreImo)
So, if you liked "OreImo" you'll probably like "Boku wa Tomodachi ...".
Both satisfy your incest needs, which in turn decrease crime and possibly make world a better place.
Ore-Imo is possibly one of the highest-profile suggestive sister incest anime ever produced.
Candy Boy positioning is a girl romance, but it's happen to be highly incestuous since both heroine are blood-related. Shortest description for prospective audience is lesbian with incest fantasies. But yes men watch this, lots of them.
Both lead male characters were unlucky enough to partner up their lead female characters who were a pain in their ass.
Both lead male character are compelled to do the lead female characters bid or at least get them out of a bad situation.
Both lead male characters were once caught by mistake of being on top of their lead female characters.
One is the sister of the lead male character while the other just pop out of no where (I just like saying that) and just appeared in front of the lead male character .
One is a comedy/ harem while the other is a comedy/harem/supernatural/ with a bit of drama.
The lead female character in "Oreimo" is a otaku and a b**** while the other lead female character in "Kannagi" is a Prima donna and a fumbling deity.
Finally, If I can have it my way,I would really like whoop Kirino's ass for being a bitchy brat against his brother and I would love to hit Nagi's head with a rolled up newspaper.  read more
Both deal with the problems of otaku (in the true sense of the word). I think both of them are terrible, terrible anime, but If you enjoyed one you'll probably like the other, so don't mine my opinion, and give it a try.
-Both siblings don't get along and hate each other
-Both main girl sibling character ends up in a complected situation, and that situation helped bring them closer together
-Both characters begin to slowly understand each other
-Both siblings character in both animes are very similar personality traits
-Both animes are romantic and cute
-Ore no Imouto doesn't really have much incest, but the other one is pure cute incest
If you're looking for deep and believeable characters, go for those two. Ef is pretty serious and OreImo's a comedy, but both are good-looking, involve some great voice acting and are surprisingly enjoyable.
Both shows illustrate how a guy whose life is going nowhere get exciting due to a girl (or girls). Both shows show said guy doing some pretty ridiculous things for said girl(s).
But be aware of (long title)'s strange brother-sister complex. It's not incest, but it gets uncomfortably close a couple of times.
Imagine it like this.Kuroneko(the character from oreimo) got her own anime or lives her own anime and it is called Tsukuyomi moon phase.If you liked Kuroneko this is for you.The main character looks like Kuroneko,talks like her,acts like her etc...You can expect a lot of gothic vampire lolitas in that anime.The biggest difference is perhaps that Tsukuyomi is a more action/romance/comedy oriented anime.
The main girl character and main boy character are a lot like Kirino and Kyousuke.
The main girl character even has the same voice actress as Kirino.
The main character girl tries to help the boy character.
There personalities are so similar it's creepy.
There's a certain uncomfortable frankness in both of these series. It's not necessarily unpleasant - the series are so candid that awkwardness naturally follows, and that can be charming in its own way. The awkwardness is often played for humour, and the candidness creates some touching moments.
Oreimo focuses more on humour while Kokoro Connect focuses more on drama, but comedy and drama are important aspects of both series.
