Yeah, but generally, it just meant putting it in a place you weren't wearing clothing really such as leg, arm, or chest. Then again, I'm pretty sure there've been plenty of symbology users who didn't really show it, but couldn't wear armor or something.
Edit: Apparently, you have those who can use it innately, get it put in genetics or something, and I think it may only be the case for offensive symbology?
All the males have it genetically and all the females have to get it tattooed somewhere that forces them to wear revealing outfits.
So this....is the power.......of JRPGs.......
