The Extermination Force (殲滅部隊, Senmetsu Butai) is the special task force of Katahara Metsudo's personal army, reserved only for special assignments. As a force made up of personnel that could apparently easily outfight a Bodyguard captain, members of the Extermination Force are incredibly powerful. They showed their supreme strength when they effortlessly defeated the renowned mercenary group, the Black Messengers.
