[Siderealist]

So gonna assume Cain just saved the Maou there...

 

[Vasqueztion]

Sigh...

[Adds another mark to the wife tally]

 

[koga88]

So he just picked up the demon lord like that huh? Or if nothing else she's the demon lord's daughter that somehow got snatched away?

 

[Akira056894]

[Gabriix]

So is she the demon lord's daughter ?
Well it doesn't really matter she is gonna be the demon wife her fate is sealed

The man's catching wives like Pokémon.

I am throwing my guess in the ring, probably not this, but a saintess to the Demon God would be cool. I honestly don't remember the whole story of all the gods anymore, but if I remember correctly, the demons follow the same pantheon as the humans, and the evil god is not the demon's main god.

[Zeroabalonie899]

Very predictable outcome. She's either the demon lord or their daughter and she will end up marrying Cain which with be the first step towards brokering a new age of peace between humans and demons.

Aaaaaand there is Lisabeth. Novel reader here. Spoilers below.

Spoiler

Yes, she’s gonna be one of Cain’s future wives.

Her position at this point in the story is the Imperial Princess of the Demon Empire, she is ranked higher than the Demon Kings/Lords. Her brother is the acting Demon Emperor at the moment. But her getting engaged to Cain doesn’t happen until after Cain helps with stopping a war between demon kind and the various countries cause of the nation that enslaved her and used her as entertainment. In that arc, Cain is proven to be even more powerful than Demon Kings/Lords, since he’s able to pretty much one shot them. Now if the manga doesn’t change what happens, Cain easily kills two of them each with a single sword strike, the third imprisoned for treason after being used by the Evil God. At the end of that arc Seth is the only one Demon King/Lord remaining until they fill in the vacancies. Cain’s engagement to Lisabeth is part of a treaty/alliance agreement and also cause Lizabeth fell in love with Cain, part of it due to how powerful Cain is.

Side note:
Demon Emperor - leads the whole empire
Demon Lord/King (Manga fanTL it is Demon Lord. Novel fanTL it is Demon King) - rules one of four territories/countires inside the empire. There are 4 Demon Lords/Kings. These guys are chosen based on their combat strength, where through physical power or magic power.
