NP.

One last question, is it possible to make a character coming from one of the big 3 families? Tohsaka, Einzbern, and Mato?

Yeah, I don't see why not, although you're going to have to tell me what family your character is coming from beforehand, so we don't have any characters be related without them knowing.
