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.

This series has the potential to become something special. Now I agree with the fact that Ch. 6 took a wrong turn but lets see if some of the angst being shown catches up with the author. Maybe he will see his fans don't like the new direction his series is going and maybe he will go back to the (in my opinion) very intriguing and engaging plot the previous chapters had. This author is extremly talented and I believe this will be a great series. Definitely a series worth reading!

Chapter 6 was tough and painful yet I felt excited and envy for Sora. He can screw Runa anytime he wants anyway, there was nothing between them just friendship.

The series got off to a hot start, in all senses of the word. The relationship between Sora and his sister Aki was immediately sexual, highly erotic, and yet very endearing. Their love for each other is very clear. And on top of that, they were caught in a dangerous love rectangle, with their secret in danger of being exposed. Aki seems to take this threat lightly; Sora does not. Nami, their sister (and Sora's almost identical looking twin), undergoes character conflict as she repeatedly finds herself the third wheel (although she doesn't quite know how far apart she is from her siblings) and is also jealous of Sora for the crush that another girl, Kana (this time not a member of the family) has on him.

All in all, this set up holds tremendous potential. Too bad the author seems to be gearing this series more as hentai than a drama/romance with sex.

In chapter 4, another character, Runa, gets thrown into the mix. In her first appearance, she is also pretty endearing. Her endearing qualities seem to vanish in the sixth chapter where she does something that, frankly, is pretty unforgiveable. I won't reveal the details of what, exactly, but she's basically counting on "all men are perverts" with Sora. Not to mention, it felt like a serious betrayal of her character considering that she had been careful in the past and yet lets the cat out of the bag suddenly and dangerously, forcing Sora into a position he'd probably rather not be in along with her.

If you're looking for hentai billed as just another seinen mag, then you might actually like the direction the manga seems to be heading in as of chapter 6, but if the plot is of interest to you, then you will probably feel a little betrayed.

I won't rate it for now; I'll at least wait until I see what direction the author takes it in.

Oh hi. Just here to mention: 1.) wincest, 2.) twincest, 3.) yuri, 4.) gender bender, aaaand 5.) boobies. This has to be setting some kind of record for ecchi theme density. Holy crap wow.

Setting that aside, this sure is an interesting one. It's kinda dark and depressing, and at the same time full of awesome.

I wanted to say that I thought this manga was excellent thus far and that chapter 6, contrary to what many have said, was the best chapter yet, convincing me that this manga is headed in a great direction. People who didn't like chapter 6 obviously were at ends with the very message it conveyed.

Just like the other readers, I thought this manga was good until I hit CH6. The first thing in my mind was WTF?! This manga now reminds me so much of School Days with an even wimpier main char. The author tried to portray the guy as sort of a victim and confused but he's having sex like he's grinding to level up in an RPG. The whole love-triangle/forbidden-love theme was destroyed in a single chapter. The author might as well label this manga as a hentai publication now cause that's all the plot amounts to. *sigh*... What a shame as it is the next chapters will probably be he doing his twin sister and the cosplay girl together while having the oneesan watch them...

Want a story?
Want something with substance?

You're looking in the wrong place. This manga may seem cute, but it's one sex scene after another. No, not sexual tension, but SEX. It's one step shy of actual sex (not showing the genitals).

Although it does begin to develop philosophical undertones at around the dreaded chapter 6 (in regarding to the sacredness of the act of sex).

It is very cute and has a very interesting story. It has its hentai scenes but the story is quite good (though the first chapter is stereotypical). It is one of the few manga that actually touched me...I found chapter 6 VERY strange and kinda painful (to me, it felt like betrayal)
