Additionally, the main goal of the ninja is not to fight, but to 'gain information (or spread misinformation) and return safely,' corresponding to today's secret agents or covert special mobile units, and such scenes as those where the characters bring around bulky iron pieces of shuriken and throw them one after another are unrealistic.
また、忍者の主目的は戦闘ではなく「情報を得て（もしくは偽情報を流布するなどして）無事に戻る」事で今で言うスパイ工作員や隠密特殊機動部隊に相当し、かさばる鉄の塊である手裏剣を何枚も携帯して、次々何枚も投げるというシーンは現実性に乏しい。
