1000年后的世界，日本的孩子们正不断地消失，只存在想象中的恐怖动物与人类展开殊死战斗。反乌托邦式的未来超级社会“新世界”，是口吐真言凭藉“咒力”就能移动物体的人类，与有着等同于普通人智力的生物“化鼠”共存的世界。乍看之下一切和平，但“新世界”的孩子们的行动被彻底地控制和管束着，不合适的记忆被消去，被认为有问题的孩子，如同不良产品般被分开处理。因为一些违反规则的小事而莫名地失去不少朋友的主人公渡边早季，卷进了人类与化鼠之间的战争。

The series takes place in the near future, when it is possible to instantaneously measure and quantify a person's state of mind and personality. This information is recorded and processed, and the term "Psycho-Pass" refers to a standard used to measure an individual's being. The story centers around the "enforcement officer" Shinya Kougami, who is tasked with managing crime in such a world.
