no rule say really that monstergirls must return to pandemonium or other place when they get a man normally they do what they want and if some one like to stay in human world or village/town they can life there too.
Kenkou was asked on Twitter what corrupted Valkyries do if they have a female charge.
"I have a question about Valkyrie. 'They escort humans who should become heroes' is what it says, but does that mean that women can be taken along by them, too?"
KC said:
"It does, yes. They can become evil spirits or spirit-users, that kind of thing. Female heroes wouldn't become Dark Priestesses, more like Dark Paladins, maybe."
He went on to say he may or may not give these Dark Paladins a profile.
