That is the thing--you also fight against moogles and everyone in the Scion seems to see them due to the Good King Moogle Mog bit too. I can only assume that moogles can reveal themselves if they want to, sorta like fairies, which is how the mailing system works as well. So if the moogles want to remove the glamour of being invisible they can.
Point is, either the game makers forgot that moogles are supposed to be invisible to every but special folks OR they are able to turn the glamor of invisibility off and on and some mortals can just see through it naturally (like having the Echo).
