 Just a quick question about Harems in the underworld.

 We know that it is social acceptable for higher class devils to have harems. But can they marry more than one person? I always assumed that they could marry one person and the rest were mistresses because of various reasons. Rias mother was born from a mistress and Akeno “only” wants an “affair” and not a marriage. However since Koneko proposed doubts have arisen.

 So is there somewhere in the LN mentioned how that works or is someone mentioned to have more than one wife somewhere in the LN to clarify my doubts.
