I mean Superia (Super + ia) to reflect Selforge City's all-female superhuman population, as well as the all-around greatness of the place. "Superbia" does have a great ring to it, but is meaning ("unreasonable and inordinate self-esteem") doesn't quite fit since Selforge City's culture is focused on empathy rather than ego/pride. Both Luxuria and Superbia have good points to makes, but they lack this overall faithfulness than nicknames are meant to cover.

Citizens are subjective beings, they can shift their nature and features just like Lawrence via their Selforge Citizen Essence, so they don't really belong to any given type. "Artificial" here refers to Seira's origin, since she was created by Lawrence instead of invited or conceived.
