浪人 Rōnin

A rōnin (浪人, "drifter" or "wanderer") was a samurai without a lord or master during the feudal period of Japan. This is a version for the future - a mechanical warrior armed with intellect and respect. "Perception is strong and sight weak. In strategy it is important to see distant things as if they were close and to take a distanced view of close things." -Miyamoto Musashi
