Maybe Belphegor is one of the few (in not the only) Extra Demon Clans to be a part of the current Devil Society.

The Extra Demons are clans that served directly under one of the Original Satans. So it would make sense for most of them to keep to themselves when the Original's died, and their decendants lost the civil war.

But that doesn't mean that some of the Extra Demons didn't want to take advantage of the new opportunities that the New Satans created.
