Kazuhiro Karasu

Kazuhiro Karasu (唐巣 和宏 Karasu Kazuhiro) is a Catholic priest exorcist who was repelled from the church because of his methods, he used to be both Mikamis' (mother and daughter) mentor, and is the mentor of Pete. He is said to be one of the best and most powerful exorcists currently active thanks to his training, but with the progressing story, he becomes more like an advisor than a ghost sweeper.
