Currently, there are three Sesshoumaru/Kikyou websites on the net, or at least three that I know of, and that's quite a lot, considering the lack of popularityof this particular couple among the huge mass of Inuyasha fans. Those places are the Heaven of any true-blue Sessh/Kiky, and they surely are worthy of your time. Visit them all, if you will. ^-^
: Hidden Hearts, the very first Sessh/Kiky website to pop up on the internet. Lots of info, fanfiction, fanart and all other kinds of Sessh/Kiky goodies. ^^
: Kaze no Kaeru, the second Sessh/Kiky that came to be. It has a great layout, some very good fanfics and interesting information. ^-^
: A Midsummer Night's Dream, the third shrine to our favorite couple. It's still pretty much under construction, but it's got some really nice content up, such as reasons why to support Sessh/Kiky and more. ^^
