Kinryu Arimoto

The "school sword action" story revolves around Magic Knights, modern magic-users who fight with weapons converted from their souls. Ikki Kurogane goes to a school for these Magic Knights, but he is the "Failed Knight" or "Worst One" who is failing because he has no magical skills. However, one day, he is challenged to a duel by Stella, a foreign princess and the "Number One" student. In this duel, "the loser must be obedient for life."

Kuroba Kaito loves to do magic, and he is a good performer. At high school, his childhood friend/girl friend tries to keep the boy inline. Of course Nakamori Aoko isn't gentle with the boy she'd never admit to loving. One morning, the classroom is filled with the talk about "Kaitou Kid," a jewerly thief who uses magic in his robberies. Kaito isn't impressed with this so called legend that reappeared after eight years, and says he could easily take the thief magic to magic. At home, thinking about his dead father who was also a magician, Kaito stumbles upon a hidden doorway in his room. He discovers his father was the original Kaitou Kid. But since he is dead, he wonders who the supposed Kaitou Kid from recent robberies is. Kaito puts on his father's hat and cape, becomes Kaitou Kid to search out the imposter.

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 Kougami, who is tasked with managing crime in such a world.
