it's definitely not a woman bc they would just use demon queen, he totally fucked a dude lol
Hmm I don't know, some mangas like to bait and switch readers though, I've seen it happen in straight romance and GL mangas before where the "Demon King" was actually a woman. Although it would be cool to see it's really a man, especially for a shounen manga.
Is the Demon King actually a woman or did one of them get MPregged?? Honestly I wouldn't mind either way but I do think I'd kinda want to see a gorgeous female Demon "King" though.
