The term 'Oriental Assassin' is a reference to the ancient Japanese warriors known as ninjas. Ninjas were highly trained in martial arts and espionage, and were often hired by feudal lords to carry out assassinations and other covert operations. The term 'NINJA' is derived from the Japanese characters for 'ENDURING' and 'STEALTH, ' which accurately describes the NINJA's ability to remain undetected while carrying out their missions.
