I'm almost certain I saw this as a character select fake in some danbooru type site recently (like a couple months back?). It'd be cool if it was real I guess, but don't count on it. Also, it's odd that it can't be that old (cuz it has the whole FateZero cast and brown hair Aoko) yet it is missing any KnK characters (which is pretty unusual considering the recent popularity explosion due to the movies).
