Huh, I just realized that Anna and Ria have been talking about how they haven't legally registered their marriage yet even though they got married by the Pope and already had their honeymoon together, but that implies that gay marriage is already legal in their world since it's never mentioned that that would be an issue legally.
Which means that the Atheist Saintess version of worst korea with nu-Catholicism as the state religion is somehow more liberal about same sex marriage than the Magical Girl Sixth Ranger version where some people have married ayylmaos and yet the MC and heroines had to live in basically a common law marriage with no official certificate.
