haha! I've got proof [and entirely too much time on my hands]
1.
Note the golden pimp chain and the open shirt so typical to pimps. Also note the fact that he's glaring; another look typical of gangsters.
2.
Here's a pic of him in a pimp suit. There's NO WAY a demon could've gotten their hands on such nice looking human clothing like that; he must have gotten them illegally through the syndicate he works with
3.
The way he's holding Hagiri's chin is very similar to the way a pimp appraises a specimen before deciding they're worthy enough to be one of his whores.
4.
He has his own mansion where he and his main bitch go to chill on weekends
5.
see the incense and candles in his boat? he deals with the distribution of illegal substances! he must work with the mafia!
6.
See? He's the leader! His most trusted bitch instructs their lackeys, but before they go out and do anything, they go to him to confirm their plans.
this is supposed to be a joke
