Ninja

A ninja is a historical Japanese covert agent skilled in espionage, sabotage, guerrilla warfare, and survival techniques. Originating during Japan's feudal era, ninjas used stealth, agility, and specialized tools to gather intelligence or carry out covert missions, often operating discreetly unlike traditional soldiers. Modern portrayals emphasize their agility, disciplined training, and strategic skills, though much of the popular image is stylized or mythologized. Essentially, ninjas were elite operatives trained in espionage and stealthy combat, functioning outside the formal military hierarchy to achieve specific objectives through subtle, covert actions.
