@OiGimmeMoreManga im gonna keep it real with you chief, humans and inbreeding dont mix. Look up Charles II of Spain if you don't believe me.

I know this is from a loooong time, but from what we have seen, this guys aren't normal humans like the one in his world, for start they can do magic, and we haven't seen a single disease in any of the kids or adults from inbreeding... besides their hair and eyes.
