Demon King makes sense.
All else aside, there are real life situations when a woman takes up a title of a male position because there simply isn't a female equivalent. This reminds me of 12 Kingdoms, where Yoko was crowned King. In that universe there were plenty of female rulers, but none the less King is the title and not changed.
Just think of "Demon-King" as one word. As a nametag. That there isn't such a thing as "Demon Queen" because such a job title does not exist.
