Oh it's a little running joke from the last two Demon King's we've had. (though the second one never actually posted ic =_=)
He befriended the one in the old roleplay (who we couldn't get back across), and he was meant to be an overprotective best friend of the next one. Now I am deciding who amongst my characters are the demon king now XD (though I haven't done CS's for any but Cody >.>)
The main thing behind the joke is that he goes on about how he will defeat the demon king, but since he doesn't know his friend is the demon king he protects him from people who call him the demon king and go after him XD
