Repure

A guy named Al goes around killing "rebel dolls", which were used as fighting machines in the war before, but their neglect over the years has made them become "rebels". One day while trying to look for some, a boy comes falling out of the sky in hand cuffs, and following him is some rebel dolls. This is a prize catch for a doll hunter, but why are they after the boy? And is that boy even human??
