I have a technical question about the SFCs! It's basically fact that the SFCs have a list of all of Vatheon's current residents. Or, well, every resident who has an SFC, anyway.

Say you're talking to someone through the SFC. Would it show the name of the person you're talking to? If so, what if that person doesn't want their name shown? Is there a way to hide or change the display name? Because when a superhero/magical girl/villain/whatever uses the SFC and doesn't want their cover blown, having the name shown without fail kind of makes it impossible for them to use the SFC as their alter ego.
