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. All wear an armband with the letters "SB" on it.
