I've left the best for last today: Kiss x Sis, a new anime announced over the weekend, based on a manga about sisterly love. And not just any kind of sisterly love, but a double step-sisterly love! That might sound a bit like Onegai Twins, but judging by the manga alone, the Kiss x Sis anime should be a lot more ecchi. Hopefully, anyway.

The original "romantic incest comedy" manga series, authored by Bow Ditama (Mahoromatic), is still ongoing, and so far it's been compiled into 2 volumes. As Zepy puts it, Kiss x Sis is "one of those manga that lies in the border between eromanga and normal manga". And you can certainly see why, if you take a look over the first chapter, available for online viewing. In short, the story (via ANN) goes like this.

"The story centers on Keita, a third-year middle school boy studying for his high school entrance exams. His two twin stepsisters Ako and Riko Suminoe - with no blood relation to him - help him prepare for the exams, but life gets too cozy between Keita and the girls."

We're still waiting for any kind of details about the Kiss x Sis anime. But I can say straight away that our incest seal of approval is as good as won.
