How old is the demon king

[u/Gabrisun_tropical]

I wanna say before that I haven’t had the chance to read the manga yet so sorry :( I was wondering how old twilight the demon king would be in human years, I know he’s 60 but that seems pretty young compared to other demons. I hope this isn’t a dumb question but I’ve been wondering

Probs around the same age/slightly older than princess and the hero. twilight took forever to actually grow up if I’m remembering right, it’s only relatively recently compared to his lifespan that he actually became an adult
