This manga is based on one of my favorite light novel series, "My Sister Can't Possibly Be This Cute". I'm so glad Dark Horse picked up the manga as they've done an awesome job with it, and hopefully someone will pick up the original novels for translation too. This series, while a little on the naughty side, also has some great social commentary on the state of how otaku (or fans to the point of mania) are viewed in Japan. It has great one-liners and the characters are crafted with care. So if you're looking for something new to read in the manga department, "OreImo" is a must read.

So, the otaku: a history. Otaku have been given a bad rap in Japan, mostly due to a serial killer in the early nineties who had a huge infatuation with anime (specifically incest-related content and lolicon-related content) as he abducted girls and killed them. It became a huge stigma, and it wasn't a good thing to call oneself an otaku. However, ever since the "moe boom" that started in Akihabara (a city in Tokyo that caters almost exclusively to anime otaku and computer otaku) about a little over ten years ago, and thanks to other groundbreaking novels like "Denshaotoko (Train Man)", it's become a little more acceptable in Japan to be an otaku.

That is, if you're male.

If you're female, it's still not really cool. However, thanks to series like "OreImo" and places like Otome Road in Ikebukuro (another city in Tokyo slowly growing more targeted toward otaku) that are almost exclusively targeting female otaku with its stores and cafes, it's slowly growing more acceptable to be an otaku. Keyword here being "slowly". VERY slowly, for girls. For guys, it's almost completely mainstream now.

So Fushimi took all of this history of controversy, and made a set of novels out of it, and eventually, manga, too, and out of it came the "OreImo" story.

Kirino, while being really popular at school and a hot fashion magazine model, still has to hide her secret of her love for naughty video games, manga, and mahou shoujo (magical girl) anime shows from everyone - even from her own family. That is, until her older brother finds out by mistake. It soon becomes a race of give and take between the siblings, peppered with a lot of tension and hilarity, to keep Kirino's secret. Kirino's choice of obsession (incest or otherwise naughty video games) is an abberation within the female otaku community - most go toward the BL (boys' love) or GL (girls' love) genres instead. What Kirino's into is mostly targeted toward guys 18 and up.

Now, this series isn't all humor. There are a lot of serious issues raised - and no, incest between Kirino and her brother isn't one of them. There's the issue of having kids 18 and under being able to purchase adult material online like Kirino does, skirting the laws about porn and profane materials where you'd otherwise have to show ID. There's also the social factor - what will happen when Kirino's friends and the rest of her family find out what she's into? Will she be disowned, friendless, and alone? What about her otaku friends online, who are also girls, who like the same things? Which road in life will she take - the appropriate one with being a model and studying abroad? Or the one of being an otaku? It almost at times feels like Fushimi is telling her own story, though I can't really confirm or deny that. It feels very autobiographical. But for the most part, it rides on comedy to make the reader more comfortable with the subject matter, which gets surprisingly deep.

I'm glad that Dark Horse has brought this series to the states, and with four volumes out for the manga (not including the spin-offs), it won't break the bank. The novel has ten volumes and is still going. Finally, Western fans will see what the social fallout is when they declare themselves otaku if in Japan, and learn more about the history behind the term itself. It's a pretty important piece of social commentary, and Dark Horse has done a great job with what I've read so far. And while it's not always appropriate for younger readers, I'd definitely recommend this to middle YA and older audiences as it's a really great series.

"OreImo: Volume 1" is out from Dark Horse Comics on September 5, 2012, so be sure to check it out then. It's made my best of 2012 so far list, and is highly recommended.

If you're a manga fan, odds are you've heard of this manga under the fan translation title of My Little Sister Can't Be This Cute. If you haven't (but are still a manga fan) then you really ought to check this out. It's quite possibly one of my personal "most anticipated" manga releases for fall 2012 aside from more Sailor Moon and volume 13 of the Kurosagi Corpse Delivery Service. (Incidentally, KCDS is also available from Dark Horse and is freaking awesome if you like mystery/thriller/horror manga.) It's one of my "must buy" releases for the fall.

This really has to be one of the cuter mangas out there and at only four volumes, it isn't going to break your bank account to collect them. Oreimo's primary charm is that it doesn't try to go too overboard with very much and lets the story unfold as it will. You just can't help but be charmed by the various characters here. I have to say that it's fairly easy for me to get interested with any manga that deals with otaku life, especially when it tries to take a look at the social stigma that being an otaku still has in Japan. (Especially if you're female.) Oreimo's primary goal is to entertain so there's still quite a bit of comedy in what it does, but there's also a good dollop of drama sprinkled within. There is a bit of fanservice here and there that's a little naughty, but overall it's rather innocent.

The only thing that might give some pause is the relationship between Kirino and Kyousuke. She has a bit of a fixation on incest manga, anime, and games, which brings up the question as to whether or not there will be anything going on between the two of them. If you're someone who likes to avoid this subject matter, rest easy. To my knowledge there's no incest and the relationship between the two of them is predominantly that of two siblings reconnecting with each other.

Overall I really enjoyed this and I also enjoyed the letters column in the back of the manga run by the fictional Saori. It's a nice touch and one that I'm sure others will enjoy. One change I noted with this volume is that Dark Horse included their translation notes in the actual manga pages (akin to how other companies do it). It threw me a little, as I'm used to them collecting them all in the back of the book, but not something that would disrupt my read. Again, this is something that is on my "to buy" list for my fall and if you're looking for something cute, it should be on your "to buy" and/or "to read" lists as well. I can only hope that if we're lucky, a company will put out the light novels that this series is based on as well.

Five out of five stars

I think there’s the kernel of a good idea in here - somebody who is outwardly cool but struggles with a hidden dorky side. In fact, you’ve seen that in a dozen other series, but done better.

The male lead is boring (not a shock for a book of this ilk) and it betrays its light novel roots by being laboriously written and full of dull narration.

Really not to my taste at all. Throw in the tee-hee quasi-incestuous bits and too much fan service for characters too young for it and it’s just another regrettable sale purchase for me.

Es tan bonitoooooo.
Aunque el anime es mucho mejor, más que nada porque ahí la historia está completa, jeje.
Y aunque aquí ya se ven detallitos interesantes, lo bueno, bueno de ésta historia llega después.
Aunque siento que el final es muy bueno, me habría gustado seguir leyendo...

Ideally I would look at this independently of the anime and judge it as such, especially since the manga came first. Unfortunately, I am not able to do so, and the reason for this is simple, the anime made an impact on me, this did not and could not even if I read it first. I watched the anime after watching Eromanga Sensei and I was expecting it to be more of the same, I was bored and looking for a trashy show that I could make fun of or possibly enjoy as a guilty pleasure. But instead of finding that, I was pleasantly surprised. I won't go into detail of why I liked it because this isn't the review of the anime, but the manga pails in comparison. The character designs are different and I'm not a fan of them. Also, the kawainess of the manga just doesn't work for me, the art just looks weird. But the biggest difference none the less is the one of tone. In the anime, Kirino is supposed to be a tsundere, but ends up being a bitch. I was bothered with this, but now I see that it's actually a good thing. Without Kirino coming off as such, her dynamic with her brother falls apart way too easily, and that's what happened here. Instead of the enjoyable awkward dynamic of siblings becoming closer after years of not speaking with each other, which is the pivotal aspect of the franchise as evident in the title, we have the tone of a cheap will they won't they romance and the awkwardness of the characters being brother and sister is the one which is not cute at all, it is simply wrong. All of this is made worse with the lewdness of the manga, and yes, with the dynamic I just mentioned, with pictures of Kirino in lewd poses, with Kyosuke's inner monologues, this manages to be even pervier than the anime. The tone is the biggest problem with this book, there is the lewdness, but the pacing is also not very good and chapters end and start pretty arbitrarily. And... that's about everything wrong with the book. I don't want to mention anything positive because anything positive is simply better done in the anime, which I would recommend instead of this book. Will I continue reading the series? Probably. I would not advise myself to do so, but I think the series will get better as other characters get their time to shine and as I accept the manga for what it is. I am also just curious as to how it is different from the anime and even if other volumes are bad I could possibly still enjoy them as a guilty pleasure.

I was curious about this manga after watching the anime. I wanted to see how different the two were. On one hand, I am not a fan of the anime. The abuse the protagonist goes through is ridiculous and even though it's to protect his sister, her attitude and behaviour doesn't warrant his actions, family or not. Yes yes, this is a sister/brother love story, but even then, the moments are few and far between where you can see that developing.

And that brings us to the manga. You do get more of a glimpse of the fact that the protagonist's sister actually cares about him and likes him, and the abuse he takes feels less than in the anime. This is partially due to the art style which fits the storyline quite well and though different from most 'average' mangas, just works. Still, I just can't get into this story and behind everything in it. Part of it may be the fact that I watched the anime, but I think it's mostly that I don't feel his sister deserves the royal treatment she gets.

Overall, this is an okay manga. I like the art, the story is interesting and I know it does evolve, as does it's characters, over time. But for the first volume, there isn't a lot here to drag the reader in other than introducing some interesting characters and fan service moments involving panty shots. If you are interested in brother/sister stories with abusive sisters, this is for you. Me, I don't think I will be picking up the rest of this series.

Non so onestamente come sia finito a leggere sta roba qua, stavo cercando tutt'altro e mi è capitato in libreria insieme a un pacco di altra roba. Penso esista anche un anime, ma non è affar mio al momento. Soprattutto perché a un certo punto mi sono sentito in difetto nella lettura di sta cosa. ok lo sappiamo tutti che i Giapponesi sono completamente fottuti nel cervello, ma c'è questo alone non ben chiaro tra fratello/sorella -minorenne- che mi ha messo più di qualche domanda in testa:
- Perché? (eh boh)
- Sto forse leggendo qualcosa che porterà a un scena incentuosa? (spoiler no, grazie a Dio)
- Chiameranno al polizia per arrestarmi? (also, no)
- Perché sto leggendo sta cosa invece che tutta la montagna di altra roba che ho in casa? (sempre boh, scusa parziale era sottile e si legge in poco tempo)

Mi ha fatto abbastanza cagare, comunque.

Rating is more so for the series, being my favorite anime since I watched it. Unfortunately the manga itself would be rated considerably lower, as it ends way too soon. Oreimo manga is max 3.5 stars for this reason alone, although I would even argue for 2 stars.

Needless to say, the ending of the manga has really upset me and I would rather they have not even bothered with making it to begin with.

Unfortunately as well I cannot find a translation of the light novel to which the anime was based on, thus I cannot experience the full series in a book form. That is, until I learn to read Japanese.

Rant over.

Después de varios años de haber visto la adaptación llego a mis manos el poder leer el manga de esta historia... Y no tengo nada que comentar dado a que es justo igual que la adaptación de anime. Si te gusto la adaptación el Magna esta a un nivel muy bueno y el arte en mi parecer va muy bien (Inu Manami y Kuroneko están en mis favoritos).
Muy recomendado

I was very disappointed. Characters are written very shallowly with only a minimum of development. The reason for the brother and sister to interact is nonsensical and there is no reason why the brother needs to help his sister.

There is a genre of manga that deals with teenage boys and their younger sisters. This manga falls within that category. Volume 1 was better than I expected. It is the first of four and I have follow-on series by the same author.

The full name of this series is "Ore no Imouto ga Konna ni Kawaii Wake Ga Nai" or "My Little Sister Can't Be This Cute."

Yeah, I'm really glad Dark Horse went with "Oreimo" instead -- it's shorter and I'm not embarrassed to be seen reading it in public. Not that the actual contents are anywhere near as pervy as the title would suggest. The story concerns Kyousuke, a perfectly ordinary high school student, and his bitchy little sister Kirino. One day Kyousuke discovers that sis has a huge porn collection hidden in her room -- and not ordinary, vanilla porn but sis-con video games -- that is romance games about forbidden love between older brothers and younger sisters. Thankfully for Kyousuke's sanity, Kirino's not into these games because she identifies with the girls but because she fancies the idea of having a cute little sister.

Having discovered that his sister is a perverted freak, Kyousuke agrees to help her keep her fetish a secret from their strict father, but in the process he gets dragged into a subculture of crazy otaku girls, most notably Kirino's frenemy, Kuroneko. Wackiness ensues.

This would be a **** manga but for two issues:

1) The artwork isn't that good compared to the original light novel illustrations. Just compare Kirino as she appears on the manga cover:



to the LN cover:



No contest.

2) The translation contains too many weeaboisms. There are certain Japanese terms that shouldn't be translated -- most food items, for example, mythological beasties, etc. -- but "genkan"? Just say "foyer". Sure, it's not as specific (a genkan is where you take off shoes when you enter a house) but since the difference isn't relevant to the story there's no point in using the Japanese term. Worse still, at one point Kyousuke mentions he's running down to the "conbini" meaning a convenience store. But here's the thing -- "conbini" is just "convenience" rendered with Japanese phonetics. What's the point of not "translating" it back to English?

I've been mulling over in my mind how I was going to review this manga for a little bit now. And usually I'm quick on my feet when it comes to if I like the manga or not, but Oreimo has me in a tight knot.

Kyousuke and his sister, Kirino, have never gotten along. She's pretty, popular, a secret fashion model, and she is into adult video games and fantasy manga, which doesn't fit her character at all. When Kyousuke finds out this secret, he promises to keep it safe, but also tried to help his sister find friends to talk to about it and leave him alone. Aaaaand, scene.

The artwork in Oreimo is cute for the most part, some times the characters look a little too over the top when trying to be cute or making a strange, but usual, facial expression. When the artist puts the girls of Oreimo into chibi modes for some pannels it was a much better improvement over the actual artwork, which is a little saddening.

As for the story, it was an interesting idea, but I found some parts to be really boring to where I'd just be skipping dialogue bubbles until something caught my eye. And there were many dialogue bubbles, a little too much on some pages, but it wasn't really a big deal, just a little note I made to myself while reading and skipping through. The ending was definitely a nice little cliffhanger for the next volume, so it does inquire me to want the next volume.

Final Summation:The drama genre definitely does tell the truth for this manga. Oreimo does have an interesting idea going for it, something I haven't seen in a manga yet, and though it has it's dull moments making me skip some long dialogue bubbles and such, I did end up enjoying it and will be reading the second volume when it comes out. I have also heard that the manga was pretty good, so I might have to check it out and see which version, manga or anime, is better.

Nerd culture in Japan is a weird thing... on one hand it seems to be their primary cultural export, with all the anime, manga and gaming-related media pouring into the West; on the other hand, the high priority of efficiency, professionalism and "normality" placed on the people of Japan means that involvement with the "otaku" scene can be seen as roughly analogous to being a Furry in America, somewhere between a bad habit and a social aberration.

The "Oreimo" novels are a sort of "Big Bang Theory" equivalent for the Japanese nerd world: an exceptionally levelheaded teenager helps his freshman little sister secretly live a double life in which she is both poster child for perfection, and closet super-geek. It's a satire on Japanese standards of cultural acceptability which can seem far-fetched or exaggerated to Americans in the current "geek friendly" media environment, but as someone who has thought once or twice before revealing that I casually play Dungeons and Dragons with friends a few times a year, I could relate.

An ARC of this book was provided by the publisher through Netgalley.

I'm not sure how to rate Oreimo, or if to do it at all. Usually I'm a fan of all manga, except I try to keep my ecchi/josei categories to a minimum (nobody wants their mind polluted at an early age, right?). And while Oreimo doesn't necessarily follow into either categories, I found myself not wanting to read it most of the time.

The reason I requested it on Netgalley was because it was manga and volume 1 of it, so me being the stupid nerd otaku I am, jumped at the chance to request a manga.

Dialog seemed all right, except that maybe there were a little too much; but overall, the idea didn't appeal to me. As in, the art was good, the dialog was good, and so was the idea, but I ended up skipping through most of the parts.

I guess this type of genre isn't for me, so no rating from me, seeing how other people enjoyed it.

Kyousuke and his younger sister Kirino don't get along at all. They are not your normal close siblings. In fact they can't even remember the last time they've spoken to each other. So imagine Kyousuke's shock when he finds fantasy anime on the floor where his sister dropped her stuff. Kyousuke finds himself reconnecting with his sister and keeping her secret for her while trying to understand her odd obsession and helping her find friends with the same interest.

I thought this story would be light and fun but I found myself bored at parts and skimming over pages. The concept of the story sounded good but a couple of parts made me a bit uncomfortable. Since Kirino is into "Little Sister" anime, it's no shock when Kyousuke wakes up to his little sister straddling him in the middle of the night. Aside from that thought, I thought the story was good.

This is the first time I've ever read manga. I know, I know that's crazy since it seems to be everywhere and everyone is reading it. I guess I just never felt the need to until now. That's why I picked up Oreimo. It was confusing at first because I didn't realize you had to read from right to left which threw me off a little bit but once I got used to it, it became natural.

I'm not sure how to go about reviewing manga so I'm just going to list the pros and cons.

Pros :

- interesting, amusing story
- characters are drawn well
- it was short but sweet


Cons:

- too many speech bubbles on some of the pages


Overall an enjoyable read, not perfect but certainly worth checking out.

Pretty art, lots of text and an interesting concept combine into a fun and light story that doesn’t take itself seriously. I’m amazed they managed to keep it from falling too far into fan service territory.
My one main problem comes from the fact that Kirino is supposed to be 14 yet she looks 10 and gets overly sexualized often. It plays into the plot and little kid art style, but it really bothered me too much to let it go.
I got the series as a gift so I’m reading all of them, but I’m not sure it’s my type of story.

So this is technically my first approach to... should I say 'Lolicon'? Well, I guess Kodomo No Jikan was actually the first one. Oreimo is based in a series of light novels which is cool, something new for me. The art is fantastic, Kirino is super cute and overall you enjoy when she's into the story, I cannot say the same about her brother. The thing is the story per se is not that good, there's some mistakes in the way Dark Horse edited the book but the writer is not as good as the artist. So it's not the best Manga I've ever read but it's a plain okay book.

Brother and sister don’t really get along. I mean they haven’t even talked in ??? well, a long time. She is a middle school student who looks like a model, a sexy model. One day the brother finds out a secret about his little sister. This secret is scandalous, if her friends find out, she’ll be ruined. He runs interference for her and gets trapped in a whirlwind.
Nice expressive illustrations. A LOL story with great side characters.

This was a lot better than I thought it would be. I'd heard that the show based on it was your bog standard moe-siscon-fanservice crap. This was, thankfully, nothing of the kind. Instead, I had fun reading this volume, and I'll probably pick up volume 2, whenever it comes out.

Anime is much better. Manga adaptation is disappointing especially because the art is very average and simplistic. The story is similar to anime, there are only several added things that will not make me buy another volume.
