Ninja's were covert agents from Japan that were hired to do jobs of espionage, sabotage, infiltration, assassination and warefare. Often times ninjas were a part of a family or guild, each of which had their own territory. Ninjas were also ranked within their families: the highest rank being jonin (upper man), then chunin (middle man), and finally, genin (lower man) who were the ones actually taking care of the missions. To be a part of the organization was an honor as the amount of training that went into this job was immense. So to wear Ninja Costumes this Halloween would be a great honor to yourself.
