Roz is a half demon and has no feelings. He used to be almost a god.
He is a psychopath, lacking emotions, the only thing you could say he "feels" would be "happiness" or "pleasure" when it comes to killing. He was banished for committing too many murders. Roz is not 100% demon, you could say it's only 50%, he has some humanity somewhere. He is constantly watched by his cousin, who took his heart and with it most of his powers, which caused a great drop in his level. He uses a trident as weapon.
