Ninjas were not always dressed in their iconic suit (which was actually a dark blue because it would not contrast on white like black would). Some times a ninja would blend in with society for espionage or sabotage mission. Often the clan would send in a women ninja which would catch people off guard. A ninja might dress up as a monk, priest and anything that would help them in their mission. Ninjas are best know for assassinations but, they only did this on special occasion. In the event of an assassination mission the ninja would use poison and not a sword because they messy. If a ninjas was catch and stayed to fight they would usally be burned in public. So, ninjas devoluped special ways to escape capture. By using water, smoke, fire, shurkins and stealth. Ninjas also were the target of assassination so a ninja was trained to their side to protect their heart. They would also hide weapons in places around their house like under a floor board.
