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.

Ok, a lot of shit is happening in this manga at the same time... but one thing is SUPER clear

The Plot is super lame and has little appeal, the art is ok, but I dislike the body shapes... in short is only the sex that keeps this manga moving, if this Hentai develops a Seinen/Mature level plot, then I will read it, otherwise, I stop at chapter 7

Stop changing the genre; this is hentai (albeit soft porn)

Spoiler (highlight to view)
I downloaded this manga looking for a regular ecchi, harem manga about forbidden feelings. I wasn't expecting all the sex (especially with people other than his sister). When something is labeled "ecchi", I don't expect to see the actual sex act, censored or otherwise. If there is any sex, it's all implied. For example, the protagonists might kiss passionately on the bed, then you see them in bed looking at each other while doing it or after; or you might see their reactions during or after, but you don't actually see them "connected" or the actual sex act in progress with as much detail as you see in this manga. At least, I haven't in the other ecchi harem manga I've read, whether they were about incest or not.

While I'll admit this isn't the kind of hard-core stuff that most hentai is nowadays, it's still hentai. In the porn industry, this would be called "soft porn". But soft porn is still pornography no matter how you look at it! Aki Sora is designed to arouse its audience the same way as any hentai out there is. So, let's be honest and stop changing the genre back to ecchi. A pervert is still a pervert even if he/she only steals underwear or looks at dirty magazines, just like hentai is still hentai, even if it's just soft hentai like Aki Sora. Even tagging it "borderline H" does not make it okay for the genre to be ecchi instead of hentai. I don't want any more people to experience what I did when all I was looking for was ecchi stuff (since when did ecchi mean "sex as long as censor out the genitalia and nothing else"?).

I have to agree with someoney3000 on the fact that this is SEX. Yeah, they don't show they genitalia but they do show the ACT OF SEX for 90% of the chapters. You don't just see 1-3 panels but you see PAGES of SEX (most of the chapters are sex). This is HENTAI through and through. It's pretty much just like the censors in Japan. You can't see their junk. If someone can prove that this is not porn WITHOUT the fact that you can't see their junk then go ahead and try but this series needs to be labeled Hentai.

Pathetic Attempt w/o Hentai

This is a really sad attempt at keeping the story away from being tagged hentai. One thing for sure, there are much more psychological titles out there that's far out of reach of anyone not of legal age.
Spoiler (highlight to view)
When we think of incest, most already jump at it and scream to the top of their lungs. Being as incest already comes with psychological theme, the author only adds more to it. From that point on, there will be more cruel play on intercourse overstepping its boundary. School Days' ending should not be ruled out.

The potential is there if you like drama, rape, and whatnot that goes beyond the list. The worst and best 'human' drama is when sex (rape, affair) comes into play.

To make it short, this is NTR censored for those whose blood rises at cheap panty flashes. This is not even worth recommending.

I just want to point out that girl who has sex with a stranger. That's bullshit for expressing one's love. I'm sure a lot of people expresses there love through a lot of ways like defecating in a bowl or some weird arse stuff but this is fucked up. to make it even worse, this is her first time too. it's either this girl lives with a broken family. she probably witness some batshit happenings. Maybe she saw her mom or dad with strangers and when she asks the parents why they're hugging (you-know-what) with strangers other than each other, the parents probably told her it's because they're expressing love to the person they love by having hot sweaty perverse u-know-what with strangers. she probably later found out it was all a lie but it was already too late. she was already way traumatized for any right reasoning in life. if the author doesn't even touch on her side of the story, then that would be the lamest turd ever.

i rest my case. there is not a normal young lady who drags a lover to a place and initiate sex with a stranger and while being fuck, moans and groans and tells the lover: "oh-yeahhhh, i am doing this cus i love you. i am having a stranger take my virginity because i love you. i am taking 2 at once... i am now trying to take 5 at once. i am now dripping wet BECAUSE I LOVE YOU! while losing her self in an orgasmic explosion.

i'll add that the story strays from 'aki-sora' like others have stated.

well, there goes my trolling. i registered just to get that off my chest.i'll be back for more.

Below a thin layer, presenting a pure and beautiful coming-of-age story, lies a dense massive core of some of the most exhilaratingly twisted psychological drama, I've ever had the opportunity/dissatisfaction to lay my eyes on! I'm not sure how to feel about this one. It's like watching SS troops in fluffy bunny suits, killing baby seals to The Sound Of Music...

lol i agree with mophin007, is this really about aki anymore? more like sora-sora instead of aki-sora. ugh. i liked this series at first, when sora was still innocent kind of. now it's suddenly turned into School Days maaan. i wouldn't be surprised if aki killed sora in the end cuz of jealousy or something.

Aki-Sora ?
Only Sora is the main character, Aki is like any other girl in this manga...
I not really like Sora, do nothing, say nothing, just follow what happen whitout any emotion. He really love his sister or anyone ? i doubt it. He look like a girl, why not, but why did he act like a frail girl ? Happily, there is Nami and Runa, only those have an interresting plot. Why not listed as an hentai when there is sex each chapter ?

what i meant guys is that when it comes to this forbidden sex and so on / its so odd cuse it cant go on real life for sure unless if it was unreal (hehe) its a good manga but its going on the wrong side with our life i cant blev that this would happen in a normal life (i mean the forbidden sex etc ..) and for sure the manga would be sure more better if they weren't (brother x sister)

I pretty much agree with the fact that it should go back to the philosophical idea of "Why is it wrong?" I'm sure it would've done better. Now that they established a... relationship with Kana, Sora pretty much screwed over the Love Dodecahedron. It makes me wonder where this is heading now. But, yeah. Runa. Hate her guts.

It starts out OK , then it looks like they were just trying to find out how much smut they can cram in to each chapter. The story line disappeared somewhere along the line and I can't even remember what it was supposed to be. If you're looking for something of substance, don't bother with this manga.
