You know, that has always bothered me. Are the Devils who have become members of another's peerage high-class Devils? The main indicator of a high-class Devil is receiving a set of Evil Pieces and forming a peerage of one's own (ignoring the ceremony, etc, that is). Sure they could have them and not use them and all, and there's nothing saying they can't join another peerage, but still...not once has there been anything other than them being descended from one of the 72 pillars that would suggest their class, and if we take the social pyramid with the noble titles as any indicator, not all of the houses of the 72 pillars would traditionally fall under the high-class Devils.
