Psycho-pass: Inspector Shinya Kogami Volume 2

More about the book

The Psycho-Pass made a better future society possible: a universal fitness app that tracks people's emotional health. But when crime becomes rare, it also becomes stranger and more dangerous than ever...and in the 22nd century the only "safe" job for a person on the borderline is as a cop--kept on a virtual leash as they hunt down the criminals they may soon become themselves!
