Aki Sora revolves around Aki Aoi and Sora Aoi, a pair of close siblings who have shared an intimate bond since childhood. During their coming of age, they each come to realize the true depth of the love they feel for each other and consummate that love in secret. They keep their younger sister, Nami, Sora’s twin in the dark about their new relationship. Nami, clueless of what is happening in her household aims to set her brother up with her best friend, Kana Sumiya. Despite these relationships Nami seems to have feelings for someone near to her too but keeps them secret.

Note: The first and third volumes will no longer be printed following July 2011 due to the Tokyo Youth Development Ordinance bill due to its depictions of incest.

So, everyone who read this, read it for an obvious reason.
Aside from that reason, this story isn't actually all that bad. Infact, it does get pretty emotionally engaging. The sex-scenes are sometimes in the right place, but many of them simply aren't necessary for the story. That said, I can't remember one that wasn't... hot for all the forbidden reasons.

So the manga was crap of the highest order and an adaptation of the hentai Oneechan no Onegai as well but we ALL read it for some reason. I even rated the hentai 1 point higher because it is at least honest and short.
The quality is bottom of the barrel for obvious reasons but the entertainment level is quite immeasurable so i may be able to recommend it for a good laugh. Just beware of bukkake, incestuous rape and orgys and a plenty.
The manga could have gone on if Akita Shoten (the masters of disasters) reclassified it as "real" porn but hey didn´t. Good i say because i was about to jump off too if it had gone on longer and his was a one time affair for me. Her (?) other near identical claptrap won´t grace my reading list. This comment section though is a must read and Badkarma´s is the best of course. Even the manga genre is locked. Amazing!
If you want to have real fun then read the chapters in reverse order as it made the same amount of sense to me as the "right" way. Finally how crazy is it that this manga is dedicated to a dead friend of the author.
I am truly at a loss of words for once.

First off, SEXY, secondly way in hell any of this is possible but it was still pretty entertaining. The plot is kinda interesting. There are three children in a family. One oldest sister and two twins. The "incest" is focused between Aki (Older Sister) and Sora (The boy of the twins) while Nami is a lesbian (For the most part)

Somehow Sora has the bitches lining up with his nervous/shy attitude, but that just makes it more fun when he is constantly seduced by multiple sexy girls.

This story kept me intrigued because ...
1. I wanted to see when Aki and Sora would be found banging and what they would do afterwards.
2. I wanted to see the next bitch that Sora would be seduced by.
3. I wanted to see seeeeeeex.
4. Boooobies.
5. ( .)(. ) ---lol

This is as close as you can get to being fully hentai. I do prefer this to hentai however But the sex scenes are pretty graphic and i'm not sure how much of a difference it would have been to sketch in some dicks and vagina's, but whatever, it still worked.

The only thing i found odd about this manga was the fact that Sora never got any of his bitches pregnant. (And that never seemed to be a concern)

8/10 ----- Really hot stuff...

Entertaining with some few artistic moments

After seeing some comments here, I wonder why there are so many people able to read manga but not genres and tags / categories on this side - as this manga delivers what the description says. Critics upon this, are just uncalled for. Critics reagrding the execution of the story however are justified by any means, specially with this story.
Nevertheless I can still recommend this manga if one doesn't held the expectation astronomicaly high. This manga is basically a hentai, so its primary focus is (who could have guessed) on the intercourse with random events leading to the obvious act. But if one is able to detach this 'hentai forced events' - let me call them that way - one will find a much greater meaning to the story: Notions of love relationships that aren't ment to be and the sentiment of unreached longig. Yes very overused topic in this genre indeed, but I don't go with the expectation of finding some kind of enlightenment in a mainly ero-oriented story. Still there were some few moments in the story were I paused and gazed upon the panel. This rare moments, which I liked art and story wise (on of them being the ending) is the reason why I can recommend this manga.
If one is interested in an average incest borderline-h story with overused topics but some intense moments, than this may be something for you.

Disappointing. There was some potential in the beginning for a complex story. Sora is pretty much used by everybody as a toy. He has no real will of his own and is pushed around whether its to do the cooking and cleaning or being forced to crossdress or as a sex toy. There was potential for some interesting psychological stuff there. Instead it becomes porn or as close to porn as you can get by omitting some anatomical details. Author could have talked about incest in society or other forbidden taboos in more detail, but instead its lightly touched on in what feels like a rushed ending. The best thing that can be said about this work was that I thought some of the art was very nice, but that's it.

Like BadKarma was saying below I started this manga hoping for a deep complex story of brother and sister love but it turned out to be a joke. Don't take this manga seriously because the main character doesn't give a shit and will stick his shit up anything that moves.

Everything I was gonna say has already been addressed by BADKARMA a few posts prior. It looks like the one good thing that came from Japan's child protection act was that it put this dull, lifeless series out it's misery.

I don't mind incest when it's done right, like Flowers of Evil or Koi Kaze (which imo tried too hard to be taboo), but Aki-Sora is just so lifeless and incoherent that it makes me very angry inside. Aki is the standard yamate nadeshiko nee-chan found throughout the hentai world. You know the one that bows bends to her brothers every beck and call, and is devoid of any personality or existence outside of her master's will. Sora is also the standard effeminate shota who's only purpose is act like a walking hard-on and engage in debaucherous sex w/ a naive youthful glee.

The main problem w/ this series seems to be that instead of focusing on one or two ideas it tries to cram all of the bad tropes, memes, and cliches from hentai into one short story and never properly develops any of it.

Oh well, the author sucks at h-manga as well, so I guess it's my own fault for giving her the benefit of the doubt.

This is a great, mature manga. Each chapter has a deep meaning that makes one contemplate. Read it slowly with an open mind, and you will not regret it. Remember, it is the author that decides what happens, not you, a right she has since she was the one that created the characters and the setting. There are not a lot of stories as well-done as this one.

The main male character is too feminine for my taste, and yes, the way the characters are drawn from a distance does make them look a little fat sometimes, but how almost each chapter leaves one thinking is simply amazing. Although the story may appear stand-alone or thw most part, the plot does progress, without the reader feeling or even needing it to, a sign of an expert mangaka.

Somebody complained that the protagonist, Sora, does not feel guilty after engaging in sexual relations with other girls, that he and his sister, Aki, do not have hesitation towards being intimate with each other, and that Aki does not feel special, however, I strongly disagree.

Every time that Sora was involved with another girl, it was because either he was forced, begged, or cornered. Remember, he was pushed to be with Kana, his shy classmate who likes him, by his tough twin sister, Nami, and he was officially available. It is not like Sora could just say, 'Sorry, guys, you see, my sister and I are "together," so I can't see anyone else.' At first, he thought that being with Aki is wrong, but he just could not answer her question, 'Why?' Their relationship's being taboo and how long it would last is also explored multiple times, such as in the chapter The Red Thread of Fate, where they think about having sex while tying a thread to their fingers at a temple, and the legend says that the couple is doomed if it rips. Sora also has feelings reserved for Aki. She occupies his thinking. Satsuki Runa, the girl who goes to the same school and lives in the same building as Sora, notices a few times as well that there is a girl that he loves. Further, Aki displays signs of jealousy of Nami and Kana sometimes. However, what she does not know can not hurt her.

I was going to say something mildly intelligent, but it appears Badkarma beat me to the punch and in a much bigger way. I don't think a professional could have written it better, and I'm quite critical of others spelling, grammar, etc.
Basically, there are plot holes a character flaws up the wazoo. The plot is that of a porno where the pizza guy delivers food and immediately gets his dick sucked upon opening the door, except the delivery boy and customer are related. I can take random comic boxes--not even the whole strip--from the Sunday newspaper every week and make a better storyline. At first, I was entertained (yea, yea, I like incest, but I'd NEVER do something like that in real life, blech *shivers*) and it seemed like it had promise. Then after seeing the same sex scene over and over, where nothing changed mentally (other than "it's not so bad fucking my sister") and they only explored more generic positions, I grew bored. This happened within the first 10 chapters. Like Badkarma said, he felt no guilt, or any emotion at that, other than the usual affection that comes with fucking your sister (lol, what am I saying... you get the idea, I hope). The only part that was half-way decent was Nami's jealousy towards Sora for fucking the chick she likes. It's a poor read and gets repetitive fast. Maybe too fast of development in every category. This probably would have been better as a oneshot. Sora has child-bearing hips. I can't believe it got serialized, but I supposed most people don't read it for the story bigrazz
