Kiss x Sis is an Ecchi, Romantic, Comedy that can be both fairly pleasurable and unpleasant to the average manga reader, since we’re dealing with an incestuous set-up. Just as the title implies, Kiss x Sis is about your average teenage boy (Keita) with 2 older twin step-sisters (Ako & Riko) that are infatuated with him and aren’t afraid to show it. This kind of incestuous romance has become very common in today’s manga, especially the H-kind, and sadly this one barely offers anything unique. The beginning of the story is just about Keita studying to pass the high school entrance exams, whilst getting into a lot of perverted situations with his sisters. Apart from that the first volume doesn’t offer much, albeit some romantic developments. The story does pick up at one point but this feeling is short lived and is replaced by their increasingly perverse High School antics, which is always trying to push the boundary between ecchi & hentai. It is at this point that the story degrades into just another generic harem; as the mangaka struggles to extend the life of this manga, with constant fan-pandering, that takes the story nowhere, except from one ecchi moment to the next.
Well for this manga to deal with twincest, obviously there must be twins and they come in the form of Ako and Riko. In the beginning there’s really nothing to differentiate between the two but as you progress you’ll quickly single out their mannerism. As for the male protagonist, Keita is just the type of person he is expected to be, a normal healthy teenage boy. This is good because his actions and reactions to his sister’s sexual advances are quite natural (in a sense), not that I condone of his actions. Well nothing much can be said about the rest of the characters because they are rather unimportant, until things shift to High School. Then they needlessly become important by turning this manga is into something it shouldn't be... a harem.
The artwork can easily be described in one word “plain”. The environments are non-existent and the characters have such a basic design, which makes telling some of them apart a tricky task. The only merit is that it is easy to tell what is happening in the panels and of course the ecchi is great for those who care for it. At least I can see some improvements as the manga goes on, but just not enough in my opnion.
Overall Kiss x Sis is a very enjoyable manga for anyone into perverted romances, mixed in with a lot of humourous sexual innuendos. Just as the title says, this manga involves plenty of kisses with sisters. And to all those who are turned off by the whole incest thing, then do not worry because they are not blood related… as if that excuse hasn’t been done before. Well in between all the perverted antics and the LOL moments, there’s still a mediocre yet nice story to enjoy, however with the mangaka constantly trying to push the boundary between ecchi & hentai… who knows what direction this could take Kiss x Sis in the later chapters.
