I thought I added this, but I guess not. Anyhow, this is Exodus - otherwise known as Vince(nt) by Ekon. He never did tell the kid his real name, maybe because he never asked.

He's moreso a devil of sorts than a demon, who eats souls. He's cut down to near none ever since meeting the brat, living out as if he were "normal." Otherwise, he's easily tempered while always grinning at the same time, and seems to enjoy other's pain and torture - especially the brat, only when it's caused by his hand.
