This is very2 late, yes i know that. I've just realized it a couple days ago that i havent visited FF XIII NA official site. Well, i have already ripped the characters and eidolons render in here. So, i only ripped the screenshots only.

I put the characters screenshot both from the JPN and US official site. The eidolons screenshot are only from the US one. Screenshots from the US site has larger resolution and its in PNG format
