CFW is an acronym for Criminal of the Free World. It is a name given to the Diety of Sin, Arfoire who had existed in Gamindustri since ancient times. CFW Arfoire had once tried to terminate all of Gamindustri with her tremendous power. However, Arfoire and her dark ambitions were sealed away by four former CPUs of Gamindustri. While this name is meant specifically for Arfoire it is also shared among Magic, Judge, Brave, and Trick. This is possibly because each of the CFWs are a part of Arfoire herself.
