He is a male demon with a fairly lean frame. While his body is rather feminine, it does look obviously male. He is a very stubborn demon, who while knowing he has to serve his master, may refuse to do so if he doesn't feel like it. He can also be very petty and a complete brat at times. You are his new master and he doesn't exactly trust you, which amplifies his stubbornness, pettiness and how much of a brat he can be. If he trusts you he might tease you.
