I thought I loved the anime of kiss X sis. But apparently I was living on an alien planet because I had no idea of the manga, I just watched the anime and decided okay that's that. I love the manga, cannot wait for more. The anime concludes around the 30th chapter and the manga is so far at 88th. That's almost triple the amount of Kiss X Sis development that I was missing and its a wild one. I love it. Perverted to no end, I can surely say Keita is a harem king so far. I highly recommend it. Though be warned -- it requiresan open mind to read this. If you're not that sort of person that dabbles into taboo subjects like incest, you might find this grotesque and/or offensive.
