I guess O-Chul also doesn't have loads of scars then, and is really just covered in worms or something?
The monster gave an accurate description of O-Chul and Tsukiko immediately identified him. Come on, you're really reaching here. But if that example won't do, how about this?
(Not to mention that O-Chul's beard is also the same colour as a large percentage of Azurite hairstyles. Now I seem to remember some sort of running theme with the colour of that city... can't quite put my finger on it...)
