Demon
The contemporary Roman Catholic Church unequivocally teaches that angels and demons are real beings rather than just symbolic devices. The Catholic Church has a cadre of officially sanctioned exorcists which perform many exorcisms each year. The exorcists of the Catholic Church teach that demons attack humans continually but that afflicted persons can be effectively healed and protected either by the formal rite of exorcism, authorized to be performed only by bishops and those they designate, or by prayers of deliverance, which any Christian can offer for themselves or others.

In addition to those Exorcists chosen by Innocence, there are Exorcists referred to as Second Exorcists and Third Exorcists. The Second Exorcists were created nine years ago as part of the Synthetic Disciple Project, forced upon the Chan and Epstein families by Central; they are created by transplanting the brains of deceased Exorcists into new, artificial bodies, in hopes of re-synchronizing the Innocence. Yu Kanda and Alma Karma are the only successful subjects in this group. Using a piece of the original Akuma Egg, members of the Black Order also created the Third Exorcists. The Third Exorcists are fused with dark matter and Alma's cells to become partially Akuma themselves; they gain mutated arms that can absorb and destroy Akuma.
