I meant to say Roygun could be married. Sorry for wording it that way. But really she could have a husband and child. She was the head of the House of Belphegor. Harems are perfectly fine in the Underworld so if Roygun decided to chase after guys like Issei, I'm sure her husband would have no problem with it.

But that's just speculation.

But really she could just want to suck him dry and not have any romantic feelings towards him. She might even take Issei's virginity. XD
