Hi ricardo. thanks for the message and sorry if i'm just answering now. haven't got time lately to visit these sites. as for your inquiry, we really have no pep files of Kamen Riders. We normally do our costumes freehand. But I did saw some files here somewhere, I will try to find it if I have the time & send the link to you.
as far as watching kamen rider I know one place where you can watch all of the 2000's or hesei era riders and there movies, and there starting to upload showa riders, starting with Black. Its on facebook.
