SchwarzLust
Probably the most comprehensive fan-site out there, with lots of kinky, romantic, and just plain cool fan-fiction, as well as nifty fan-art and other goodies starring the Schwarz Boys!
TOTM Presents: Weiss Kreuz on Prozac!
Ever wonder what medications our poor boys need? Or want to read Aya's guide to brooding? Search no more!
SCHULD
A very awesome shrine concerning our favorite should-be-stuffed-in-a-straight-jacket, Farfarello!
Kenomi
This site has LOTS of stuff on Ken and Omi, much more than your usual shrine. Don't miss this one, especially if you are a fan of these two!
Weiss Kreuz
A page made by a self-proclaimed Knob. Has loads of crackpot theories, and really well-written profiles for every assassin on the show! I spent two hours at this site...
