If you pay attention to what's going on in the import world, you probably already know that rhythm game fans have been losing their minds over Sega's Project Diva, the recent release starring virtual popstar Hatsune Miku. Japan has been obsessed with the character for some time now, and there's even a version of 4chan dedicated solely to her (yep, you guessed it -- Mikuchan).
We spotted a couple of pictures of a Left 4 Dead mod there, starring Miku herself wielding some wicked looking guns. A user on the Mikuchan website made the mod himself, and is still working on it. If you hit the jump, you can see another video he made where Miku is actually The Witch (warning, it gets bloody!). Unfortunately, there's no information about actually downloading this mod, but if you keep an eye on the thread hopefully we'll find a way to do it eventually.
