Looking for a Ranma fic

[thiagotm]

I'm looking for fiction where Ranma and Akane are descendents from monsters/youkais hunters clans if I'm not mistaken and are helped by other members from their clans and their friends to kill an ancient evil (and realize a prophecy that if I'm not mistaken was made at the 1st chapter, prologue)? it was at fanfiction.net but maybe it was taken down after they deleted a lot of fictions.

I think I remember that one. It was on of the first Ranma fics I've read, so it must date back to 2005/2006. Can't remember the title, though.
