After the crime rate in The Third Toutou Empire spiralled out of control, a law was established to help expedite trials and relieve pressure on the overcrowded prisons, which were filled to the brim with criminals who had been sentenced to life in prison without possibility of parole.

According to this new law, trials could be held and the accused sentenced to death even if they hadn't been captured yet. In order to execute those who had been given this kind of advance sentence, the Special Executions Police Force was created.
