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.

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.

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.

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.
