Exorcists

Exterminators are Angels that are sent from Heaven to kill a portion of Hell's population whenever Hell becomes overpopulated.

Trivia

 * According to Vivziepop on YouTuber Artisim Podcast's Episode 59, only the Exterminators can really kill the citizens of Hell using their special tools.
 * Sometimes when a killing is done and if tools are left behind, other demons will steal them and sell them on a black market so demons can kill others.
