For those among us who play UT2004, I just thought I'd share with you a wonderful site that has many many character models and skins, but more specifically, a fair number of them are anime and manga derived models and skins:
Best one i've found is an incredibly well done Catgirl model called Marygold. The Femmina skin for her adds more of an anime look. Simply beautiful. Even if you don't plan on playing with her (as in, with her as your character model, not... um you know... yeah =) ), she's well worth a good ogling.
If you play Onslaught online, add Shinobi4 to your UT2004 buddies list, ne?
