Fanfiction.net - This website has a large variety of different fanfictions, not only to InuYasha, but to many other great anime series' as well! I took a look at a few of these fanfictions, and they are all great! Each fanfiction lets you know what it is rated, what language it is in, what type of fanfiction it is (ex: romantic, horror, comedy), and how many words there are in each writing piece. This website is very reliable and will give you a good taste. Just click the link to the left and you will be directed to the fanfiction for Kagura. Enjoy your reading!
