CAREN ⇨ A priest who (highlight for spoilers) and is the daughter of Kirei Kotomine. I've been meaning to ask how death works in this game so I can figure out the resolution to a thread with someone else, but other than that she's pretty flexible and open for plots. She might be a lot of fun for those who are evil in nature, think evil thoughts, or for those who want to use someone to find demons!
