I'm afraid not. :| Most of what I've found is drabbles, and there is a comm for them: morethanzero. Everyone is more obsessed with Ritsuka and Soubi (not that it's wrong to be obsessed with them, it just sort of overwhelms everything else) or the Male Zero. My favourite character is Kio, who also gets very little love.

I think we're going to have to write the fic ourselves. :|
