I'll like Saber to be my bodyguard. Really.
EDIT: Oh, to explain why I don't choose any of the 5 that jparker mentioned, it's because all, except Inuyasha, are cliched. And all aren't my type of bodyguards that I want, anyway.
EDIT, EDIT: Oh, and I wouldn't want a male bodyguard, anyway. Female bodyguards are better because we can protect each other :p
