The Americans imagine the ninjas flew through the sky and disappeared, like Superman, waving ninja swords around, sneaking into the enemy ranks and assassinating generals…WRONG.

The ninja does the two things that are performing espionage and strategy. The methodology for implementing espionage and strategy is called a Ninjutsu. They were the spies, that are the one carefully gathers intelligence and while in times of war, Ninjutsu was called the art of “entering from “nearby”, wherein ninja would constantly gather intelligence concerning the enemy, thinking of ways to beat the enemy, but not fighting the enemy directly.

A Ninja who rationally thought of war by the intellect as great, and war by military strength (weapons) as foolish. Therefore, a ninja who swings their ninja swords was called the lowest of the ninja.
