Polygamy "state of marriage to many spouses" or "frequen "state of marriage to many spouses" Is menioned several times in the story line.

In  volume 2 New Life Asia states,  “......Auu, looks like there’s only hope for polygamy.

In volume 8 Life 1 Ise states, Shit! I want to have girls in both my arms, and want to talk about polygamy!

And even though Ravel wanted to come and be close to Ise her family is putting her future in marrying Ise.
