I remembered a neat novel I once read: Blood Warlock a Succubus Partner in tthe Apocalypse. And at the moment I am reading Apocalypse tamer. So I wanted to ask if you know any other novels with similar premise where a male MC has a non-human romantic partner in a system apocalypse setting. It doesn't necessarily needs to be an overt romance, it could be a romantic subplot. Also preferably that MC is a mage class or mage adjacent or maybe a dexterity based one.

Examples of what I meant:
Everyone else is a returnee
Nightmare Realm Summoner
Blood Warlock a Succubus Partner in the Apocalypse
Apocalypse tamer
