Sho doesn't advertize what he is because basically in his world/city, you were either part of the crime syndicates or you were associated with it. He figures that people can figure it out themselves just by looking at him.

They can meet any where and any time. Sho likes to hang out in the markets arguing with the sellers because it's a lot like home that way GACKT admits he was kinda drunk during that program hence his even more derpy moments than normal derpness.
