Kiss x Sis is the TV series to the OVA and manga adaptation. It is about a boy, Suminoe Keita, and his everyday encounters (often perverted) with his older twin sisters, Ako and Riko.
The plot of the series is light, you can almost think of it as slice of life if you take out all the erotic antics from the equation. But then it wouldn't be AS good as it is now would it?
Many of the scenes aren't much better or much worse than what you would see in a regular show this season. Although the details of "certain" scenes clearly had much more dedication for you know.....Obvious reasons.
The soundtrack also seems to be similar to the art as it won't stray too away from the industry standard. You have your mix of erotic music, cliched moment insert songs, and the OP and ED (which were decent).
As for the charactere s of the show, I think they were nicely done. I think its safe to say that Keita seems like a reasonable representation of most average guys. Now on to the bread and butter of the show, Ako and Riko. While the twins aren't the most stellar or beautiful characters out there, their love and borderline actions to get to Keita that draws you in, thinking "Oh god go for it" or "DO IT, DO IT". I do think the twins' were a bit over the top, trying to get off and get into Keita's pants all the time. But its definitely their appeal that has you coming back for more.
It would be a giant lie if I said that I don't enjoy the show. Each episode has a different means of seduction or...enjoyment. And I truthfully admit smiling like a complete idiot at the end of each. Bluntly speaking, it is borderline hentai/porn. The show knows how to take foreplay (for you kiddies reading this wait a few years before find out :P) and make it so much more appealing. So far each episode is a c**ktease and you know kinda left me "unsatisfied."
I originally read and watched the manga and OVA, so the TV animation certainly met my expectations. Although I am a little disappointed that more couldn't be done to improve the quality of the show in terms of animation and music. I think for many of the viewers, its a hit or miss show. If you don't like perverted stuff, it really may not be for you. But if you don't mind feeling a little horny after watching an episode, I definitely recommend this.
