The baidu people have it and they will start translation once they get sauce. In the meantime, they put up some pictures, which I DLed. I've also TLed the character sheets and blurb for the next volume, but please take them with a pinch of salt.

Thanks to MyNameHere for calling it to my attention and MPT for TLCing it.
