I've gone through every single one on Noire Sensus, even the slightly dodgey ones. The Tekken fic part of that site seldom updates anymore, I'm not sure why, everyone seems to have lost interest after Tekken 4. The period between T3, Tag and T4 generated the most fic, but now it's gone downdowndown.

Pimp away! I'll friend you so I can access them. :)
