*Little TW, mention of demons and demonology. If that's not your thing, click off now.

Wow, I've been active in this forum, huh? Anyhow, I have a character who's demon-based and I'm having trouble figuring out which class he should be placed in. I'm thinking of placing him in the Ars Goetia class, but I'm not entirely sure because I'm not well versed in demonology. If anyone could help, that'd be great! Here's a picture and a general description of his powers and temperament (Credit to picture belongs to me, TheFlyingKitten, aka Pack #163706):

Powers: Joba has the ability to shift into any animal he pleases. He has attempted to shift into a human before, but the closest he's come is an uncanny Bonobo. He has the ability to invert his chest, meaning that he can stretch his body in just the right way that his ribs are forced out and seem to become sentient jaws. He has no specific job, like most demons (Stolas, Paimon, Vapula), but he likes to use his powers to act as a malevolent jokester.

Temperament: Mild temper, anger that can easily be controlled unless someone gets on his nerves. He enjoys being summoned and pretending he can offer humans gifts, eventually stealing their souls so he can cheer at their misery.

Once again, any help with his class placement is greatly appreciated! ^^
