Haze is a mercenary monster hunter. People who can afford him get him to either capture or kill and sort of creature or being they so wish, and he'll get it for them, no questions asked. Due to this job of his he tends to keeps to himself and puts on a completely different cover personality for when he goes out and interacts with 'normal' people. His reputation and credibility is very important to him, mainly due to the possible consequences there might be from failing a hunt. His failure rate is very, VERY low. He has a large, kinda pudgy, pet rottweiler named TK, and that dog is his best friend in the whole world. When he's out hunting that is generally his outfit, along with the gas-mask to both hide his identity and to protect him from some of his more preferred weapons.
He is in fact human, but some people question it because of his oddly green eyes and his canine teeth are pretty pointy, but he's honest to goodness human.
