It's not a different universe, The First and Last Demon's main characters appear and Clem and Wist in turn appeared in that book too, you probably didn't read far enough.

Honestly as Hiyodori number one hater I think this is my favorite book from them. Still too little romance though. Next book is going to be another Clem and Wist book which is kinda of a bummer for me.

I created a tierlist thing for unwell people as me. My main complaint is as always, they can write romantic things but can't write romance which is such a wild thing....

Lastly, 'Masks Worn By Magical Wives' might have the worst cover and title of them all.
