Hiromichi Kojima, the star batter of the Lycaons, heads to Okinawa to train and bring himself out of a slump. There, he meets Toua Tokuchi, a 134 km/h (83 mph) pitcher and the undisputed king of a gambling form of baseball called “One Out”. At Kojima’s urging, Tokuchi signs up with the Lycaons. His contract differs form the usual, though, in that he gets 5,000,000 yen for every out he pitches, but loses 50,000,000 yen for every point he gives up.
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” in the anime’s title refers to a standard used to measure an individual’s being. The story centers around the “enforcement officer” Shinya Kōgami, who is tasked with managing crime in such a world.
Somewhere in the vast sea of the Internet, there’s a website that can only be accessed at the stroke of midnight. Known as the Jigoku Tsushin, rumor has it that if you post a grudge there, the Jigoku Shoujo will appear and drag whoever torments you into the inferno. Very little is known about the girl—all we know for sure is that she lives with her equally enigmatic grandmother, that three magical straw dolls accompany and serve her, and that whenever a posting on the Jigoku Tsushin moves her, she becomes the Jigoku Shoujo.
Ryūgamine Mikado is a boy who longs for the exciting life of the big city. At the invitation of his childhood friend Masaomi, he transfers to a school in Ikebukuro.

From then on, the existence of supernatural cases and a gang called the Yellow Scarves will rise to the surface, and Ikebukuro will pushed to the breaking point.
