Sora Aoi has always been close with his siblings. But while Nami may be his twin sister, he and his older sister Aki share a different kind of relationship.

What began as an encounter with Aki in the bath led to a startling realization for Sora: he is in love with her. But while Sora is hesitant about his forbidden feelings, Aki confesses that she has always loved him. With their affections out in the open, the two begin a secret relationship.

[Written by MAL Rewrite]


Aki-Sora was bundled with the release of the limited-edition third volume of the manga.

Aki-Sora isn't your run-of-the-mill brother-sister incest story. There have been too many OVAs to count where a boy and his step-sister(s) of no blood relation at all, made quite clear early in the story, have expressed their forbidden love. One of the attractive points of Aki-Sora, though, is that Aki and Sora are, in fact, full siblings.

My personal feel after this anime was: What did I just watch!?

Sure, the art is quite good, same as the story line, which is as good as it can be in just 1 episode, but seriously, if you can't stand brother-sister relationships with no limit at all, you will find this anime shocking...

Also, it comes quite close to hentai, it is extremely "detailed".

Anyway, if you're planning to watch this OVA, prepare!

One of my old banned reviews. The original review was taken down for not going into more intricate plot detail...even though I explain the entire plot.

Aki no Sora is basically the anime version of this cultural trend...only it lasts for 30 fucking minutes!

Aki no Sora is the tale of a young ...
