http://en.wikipedia.org/wiki/Shuffle%21
Wikipedia already has a massive article on SHuffle and individual biographies for each girl, at least for Kaede and Asa at the moment. I haven't had time to load up Nerine, Primula, and SIa's. The pictures are there as well.
He can use that as a reference and I've already loaded up their name meanings (At least what I found but I could be wrong) for each girl. Of course, better for a website since somebody vandalized Kaede's biography but luckily someone fixed that.
