What the hell. That isn't Saber thats for sure, the ahoge on top of her head is missing. So either this are characters for a new game (which would be good) or characters for one of Nasu's side projects (Novels and such) which would actually be good too
Neither. It's from an old novel called Vampire Wars which Takeuchi did the art for (As the tags now indicate). It wasn't a TYPE-MOON project and Nasu had no part in it.
