What are Korean ninjas?

Answer 1

Technically, ninjas don't exist in Korea, however like every country there are assassins. Don't know why people think only Japan had assassins, China and Korea had such assassins as well. The problem is that these societies were very secretive and not much is known about them. In Korea, they were called the Sulsa warriors, not ninjas...though they both were elite spies. The Sulsa were mysterious and quite secretive and both wore black clothing, but the Sulsa wore different kinds depending on the environment and the Sulsa don't wear hoods but headpieces that could be used as a bag for many things.
