Ore no Imouto ga Konnani Kawaii Wake ga Nai

Similar art style, jokes, even characters and setting are kinda resembling. If you liked one you will probably like another. 

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 

Both feature girls with outwardly perfect lives who hide their otaku hobby from family and friends. Both of them eventually outwardly embrace their hobby. 

Both are mainly focus on Dating Sim game/Visual Novel Main character in each is deeply interested in adults game and tend to distinguish 2D and 3D world clearly  

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! 

The protagonists intially reject their Otaku nature through fear of ridicule.  

A story about a determined protagonist who has to take care of a rude but at the same time weak girl with a tsundere personality. It also has the potential to turn into a real drama. 

Male protagonist and storyteller, while the story is actually about a tsundere girl who walks over them and terrorises them. Both guys are cynical and comical, without them realising it. 

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 

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 

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. 

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". 

Both are about otaku girls and their friends and family- though there's more drama in OreImo, and Lucky Star is a lot more easy going 

- Both a story about a brother and sister where one wants an incestuous relationship - It's not as blatant, but the art is similar as is the storyline - Incest relationship without harem 

Shows in which the main characters have embarrassing (otaku lifestyle) secrets that they are trying to hide from their friends. And of course, they were not successful in hiding their secrets. 

- Incest. 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 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 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  

Blue haired character helping orange haired character, orange haired character helping blue haired character. Characters share a similar sort of 'love-hate' relationship. 

Similar older brother themes. As an older brother myself, I can relate heavily to both of these. Both of these (and Bakemonogatari) are in my all time favorite shows. 

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. 

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. 

Both involve characters with "frowned upon" hobbies, where these hobbies not only help them make friends, but also helps them become closer with siblings. 

Both are about a relationship between an older brother and a little sister. At first, in both, the sisters hate their brothers but after some (or maybe a lot) situations, they end up loving them. 

Both of these series involve incestual relationships with the MC and their sister who are related by blood. 

Harem shows which delve into otaku culture, particularly visual novels. 

Both themes of having to balance otaku and real life are prevalent in both anime. Also, some lighthearted jabs at otaku culture are present. 

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. 

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 

Both are incest centered comedy anime about a boy and his harem of teenage girls. 

In both series the MC takes an older brother/guardian type role for a cute girl(s). There is a focus on overcoming obstacles as a family and a light sense uncle/bro-con (crush) in both also.  

It gives the same way of feeling and have a similar view on the sex; what's more the main chars both are crazy are a little bit insane and a boy is shy and don't know what he exactly want. 

Both feature main characters who are otaku and deal on some level with the issues surrounding their hobbies. 

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 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.  

the protagonists of their Anime are very similar both as physical appearance, both as a character; Oreimo and Nisekoi are both comic and a little harem but I find it even more comical Oreimo 

Both anime about sister and brother. In both anime main girl protagonist voiced by Ayana Taketatsu. But there is lewd content in Kiss x Sis. 

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. 

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. 

-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 

Not much alike but in both have a girl causing problems to the protagonist and the characters Yamada Aoi and Gokou Ruri are a lot alike. 

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 

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 

If you take a look at the premise and synopsis of both shown, they are nothing alike. However, if you start watching them, you'll find that the protagonists of both shows are, at heart, the same: Kirino and Houtarou are willing to open their true selves up, after getting a little push from someone close to them, or someone being curious. If you liked the steady development in characters, or just seeing two completely different personalities interacting with each other and learning about themselves, you'll probably enjoy Hyouka and OreImo. 

For this recommendation, I simply want to point out that the only reason to watch these two is for their kuudere girls, Kuroneko and Shizuku respectively. It counteracts the annoying insufferable god-awful tsunderes they are partnered with, although I'd argue Haru is way better than Kirino, so you might have a hard time watching Oreimo. 

After i heard the reason behind why Mihari transformed her own brother as a cute little girl, my first thought instantly jumped up onto oreimo, since they both kind of share a similar bonding sister-brother background character history. Little sisters were a prodigy while the brothers were a complete up-to-no-good person that needs to be fixed by their own sisters. Ofc they both, which refer to also both sisters and brothers, had their different approach to comprehend the situation, which also differentiate by how they flow the bigger image of their story toward the whole story. I recommend to watch this two.  

Do you like anime with very controversial endings? Well do I have the pair of the century for you… However that is their only similarity. Oreimo focuses on hiding your true self from the public, afraid that they might judge you (with a little spice in the mix). WEP has depressed and suicidal teen girls and tackles subjects like depression. 

They're both comedy shows that require a good knowledge of Otaku culture to really be appreciated 

Quite possibly some of the most "worst" anime out there. The real similar quality between the two is how they both need to be driven through in one go as any long time may cause demotivation. Then comes some of the most controversial endings anime has to offer. Quite a few dumb characters here that make you want to stop living whenever you encounter them too. They are hard to sit through but they both have this same unique effect given off when all is said and done. 

Hmm, I can't think anime as similar as this other than Oreimo Both anime have a brother-sister relationship story turned into a romantic story. Many people opposed to that idea. But at least Da Capo is better than Oreimo. 

Both series feature incest relationships, although in Domestic na Kanojo the sisters and the MC are not related by blood while the sister in OreImo is. 

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).  

Take Oreimo and make it a hentai, yes, there's doujinshis, but here's an anime pretty similar to that, in the beginning two of the females start acting pretty tsun (like Oreimo) to later have passionate sex, and of course there's a little sister in all of this, who is blonde (see, like in Oreimo), if you have a thing for wincest you definitely will like it and even if you don't there's the other two girls to chose from or just the idol part of it all (which also kinda was in Oreino, I mean she was a model and whatnot). 

both insist otaku culture to other people, same studio, same licensor, same feel, similar art, both sibling theme, et cetera 

Both animes talk about the lives of otakus. 

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.  

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. 

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. 

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 have female characters with interests in Eroge. They also both have girls that wish to create a successful eroge, though it is out of the norm, being they are female. 

They both have some character development and a similar story like the relationship between brother and sister.OreImo is much more fun then the Canvas 2.C2 can be little dramatic some time.  

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. 

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. 

-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 

Both anime deal with problems regarding family relationship. If you enjoyed Usagi Drop, i'm sure you can enjoy Ore no Imouto too. 

Involves a girl hiding her life in a maid cafe. Similar them but Kaichou wa Maid-sama! has a lot more romance! 

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. 

Series that take a semi-serious approach in portraying otaku life. While otaku life style is not the main point of the series, it is a vital plot setup that is required by the story.  

although both anime has similarity as a harem romance comedy involving sister romance, both anime has a different character set for both the male protagonist and the sister. if oreimo has a tsundere princess pride of a sister with a somewhat servant pride of a brother, hensuki provides the viewer with a sister that shows her loves towards his brother in a blunt way. if you are a sister complex or sister romance addict, definitely give it a go. 

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. 

i loved watching high score girl so much. enjoyed all the episodes and made me feel great the entire way thru. very similar experience with ore imo. would definitely recommend. great story telling. another great coming of age story 

Both had original anime endings that weren't a part of the source material and later released OVAs that continued the story from the manga (Tsubasa) and lights novels (Ore no Imouto). 

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 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.  

Similarities: 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. Dissimilarities: 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 anime are pretty laid back, slice of life anime. If you loved Azusa, her voice actress, Taketatsu Ayana is the heroine in the Ore no Imouto series.  

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.  

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 

the main characters are both clueless, about the girls that like them it's also a great laugh with similar problems. 

Both anime are about the love story of a brother and sister relationship.
