Though he gets consumed and controled によって evil madness によって a demon god, without it, he's still pretty insane! But he can also be charming and funny all at the same time XD He's insanely and adorably mad :3
Tamama! His hobbies include: -Doing anything and I mean ANYTHING to get his beloved Sarge's attention -Making That Woman suffer -Killing flies with his crazy rage breath Oh yes, and he loves pocky. All flavors, he says.
Amaimon. He's cute as fuck. I wouldn't exactly say he's INSANE, buuut...he is very sadistic and gets bored extremely easily, and the only way he can cure his boredom is によって fighting someone strong enough that he won't kill almost instantly. (or not so strong that they'd kill him) Which is why he's so obsessed with Rin and wanting to make him suffer. He's the only working toy he has and he barely gets to play with it. (probably in Amaimon's eyes. XD)
