Gremory

One of the odder demons in hell, he is fairly good friends with Lucien. 

He's the demon of corruption, and is often causing havoc on large companies and leaders, giving them bad thoughts and ideas to watch their business slowly crumble to the ground.....

His personality can be described as a bit crazy and a whole lot of childish,  but underneath his mask is a very smart indivudual who knows what he's doing...
