Temple of Ranma's Sailor Senshi Seifuku

Sadly "Project NK Ranma" which you titled by the authors name, Celeste Byrd, is a truely dead fic as she passed away back in November of 2001. The first 6 chapters of the story can still be found on http://www.asynjor.com/fanfic/

Er that "update" to Thrice is from Monday, June 21, 2004...
And Ishtar updates Family Values to chapter 10 http://ishtar.fanficauthors.net/Family_Values/Hogwarts_at_Last.php

I think the story you are looking for is "The Day Sanrio Died" and it was hosted on Bridget and Jamie's Fanfics and Food, http://www.gci-net.com/users/w/wildeman/ however the site seems to now be defunct. I was able to find a copy in the eyrie archives... http://archives.eyrie.org/anime/Mi...
