Kazuhiro Karasu

Age: 45 A male Catholic priest exorcist who was expelled from the church because of his methods, he used to be both Mikamis' (mother and daughter) mentor. He is said to be one of the best and most powerful exorcists currently active thanks to his training on Myoushinzan, but with the progressing story, he becomes more like an advisor than a ghost sweeper. In one point of the manga, it is suggested that he will become the chairman of the GS community one day. (Source: Wikipedia)
