Counterpoint to the whole skin color thing, the Miroku's are portrayed with pale skin, not medium-toned skin. I think the distinction is similar to the real-world situation: caucasian skin and East Asian skin are both fair, but are technically different-colored.

As for the wall issue, nothing about it really makes sense. We have so little details on it that it's hard to speculate. Like I said before, multiple kingdoms are mentioned in the East, so I'd rather we put the Wall's location as an unknown state somewhere in Bolganio for the time being. Who knows, the Tailor novel or an upcoming databook may give us more information about the issue.
