Black Crown (黒梢, Kurokozue; Literally "dark treetop") is a global militant terrorist organization motivated by the beliefs of Kurozome. It operates as a network comprising both a multinational, stateless army and a radical Kurozome movement calling for the return of the One and a strict interpretation of Kurozome's missions. In its modern form, it is believed to have been founded some time after the Fourth Shinobi World War, though by who is unknown.
