It's the 2060's, and Japan has perfected "The MRI System," a piece of neurotechnology that, when given the brain of a person who died within the past 48 hours, can analyse the visual memories contained within; even being able to give scientists a look into what the deceased saw in their final moments. Needless to say, this is a highly regarded - and greatly feared - method that has been placed under stringent restrictions and is only authorised for use by a special police unit, Section Nine, for the investigation of baffling or high-profile crimes.
